Self-perceived cognitive function and neuropsychological performance in women with fibromyalgia

BACKGROUND: Cognitive dysfunction is a common complain in patients with fibromyalgia (FM). Aim: To assess the perceived cognitive function and cognitive performance in women with FM. MATERIAL AND METHODS: Cross-sectional study including 100 women with FM (FMG) and 100 healthy controls (CG). Self-perceived cognitive functioning was evaluated using the Functional Assessment of Cancer Therapy Cognition scale (FACT-Cogv3). The neuropsychological performance was assessed with the Trail Making Test (TMT-A, TMT-B), Digit Span test (DS), Barcelona test (DS-F/B) and the Frontal Assessment Battery (FAB-E), Spanish version test. Results: The mean scores of all cognitive self-perception factors and all neuropsychological tests were lower in the FMG (p < 0.001). Over 90% of the FMG took longer than the population mean (P50) to complete the TMT-A and TMT-B tests, while in the CG, 1/3 took longer than the P50 in both tests. The minimum expected scores for the DS-F and DS-B tests were not achieved by 40 and 9% of FMG participants, respectively. According to FAB-E, 54% and 24% of FMG were categorized as fronto-subcortical deficit and fronto-subcortical dementia, respectively. CONCLUSIONS: Women with FM have a higher perception of cognitive dysfunction and lower cognitive performance in objective tests than healthy women. More research is needed to explore the clinical, psychosocial, and sociodemographic characteristics that predispose to cognitive deficits in this group of patients.

ANTECEDENTESA: La disfunción cognitiva es una queja común en pacientes con fibromialgia (FM). Objetivo: Investigar la función cognitiva percibida y el desempeño cognitivo en mujeres chilenas con FM. MATERIAL Y MÉTODOS: Estudio transversal incluyendo a 100 mujeres con FM (GFM) y 100 mujeres como controles sanos (GC). El funcionamiento cognitivo autopercibido se evaluó mediante la prueba Functional Assessment of Cancer Therapy Cognition scale (FACT-Cogv3). El rendimiento neuropsicológico se evaluó mediante las pruebas Trail Making Test (TMT-A, TMT-B) y Digit Span test (DS), Barcelona test (DS-F/B) y la prueba Frontal Assessment Battery, versión española (FAB-E). RESULTADOS: Las puntuaciones medias de todos los factores de autopercepción cognitiva y todas las pruebas neuropsicológicas fueron significativamente menores en el GFM. Para TMT-A y TMT-B, más del 90% del GFM tardó más que la media poblacional (P50) para completar las pruebas, mientras que en el GC aproximadamente 1/3 requirió más tiempo que el P50 en ambas pruebas. Un 40 y 9% del GFM no obtuvo la puntuación mínima esperada para las pruebas DS-F y DS-B, respectivamente. Según FAB-E, el 54% y 24% del GFM se clasificó como déficit fronto-subcortical y demencia fronto-subcortical, respectivamente. Conclusiones: Las mujeres con FM tienen una mayor percepción de disfunción cognitiva y menor rendimiento cognitivo en pruebas objetivas que mujeres sanas. Se necesita más investigación para explorar las características clínicas, psicosociales y sociodemográficas que predisponen a los déficits cognitivos en este grupo de pacientes.

Estudio exploratorio para la validación de la Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) en la población con esclerosis múltiple remitente recurrente del Hospital San Juan de Dios en Santiago de Chile / Exploratory study for the validation of the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) in the population with recurrent remitting multiple sclerosis of the San Juan de Dios Hospital in Santiago, Chile

La evaluación cognitiva en personas adultas con esclerosis múltiple (EM) es un área fundamental a tener en cuenta en el proceso de intervención, debido a la alta prevalencia de deterioro cognitivo. En la actualidad, se ha recomendado la evaluación cognitiva por medio de la BICAMS (del inglés Brief International Cognitive Assessment for MS), que es una batería específica para evaluar a personas con EM, pero que no cuenta con validación en nuestro país. El presente estudio tiene como objetivo identificar el impacto de algunos factores clínicos (meses de evolución de la enfermedad y nivel de discapacidad) y personales (sexo, años de escolaridad y edad) que influyen en las medidas cognitivas de la BICAMS, a fin de contar con información relevante y precisa en un futuro proceso de validación. La muestra estuvo constituida por 38 personas con Esclerosis Múltiple Remitente Recurrente (EMRR). Los resultados mostraron que de los cinco factores clínicos observados, solo edad y sexo influyeron de manera significativa sobre los puntajes de las tres pruebas de la BICAMS. Por lo tanto, la validación de esta batería para la población chilena debiera incluir y/o controlar ambas variables de edad y sexo.

The evaluation of cognitive aspects among individuals with multiple sclerosis (MS) is key when considering intervention, because of high prevalence of cognitive impairments. At present, cognitive evaluation has been recommended by means of BICAMS (Brief International Cognitive Assessment for MS), which is a battery specifically constructed to assess individuals with MS. However, the battery has not been validated in Chile.The present study aims atdetermining the impact of clinical factors (months since condition's diagnosis and severeness level) and individual factors (sex, age, and years of schooling), which is expected to be accurate and valuable input for future validation processes. Sample consisted of 38 people with remittent-recurrent multiple sclerosis (RRMS). Results showed that only age and gender do significantly impact cognitive performance on all of three BICAMs subtests. Therefore, when validating this battery for Chilean individuals, both age and gender should be included and or controlled.

Cerebellar cognitive affective syndrome due to cerebellar atrophy: case report / Síndrome cerebelar cognitivo-afetiva secundária à atrofia cerebelar: relato de caso

Cerebellar atrophy is a rare and challenging disease with few descriptions in the medical literature. Motor impairment is mild, but behavioral and linguistic alterations stand out, in what is known as the cerebellar cognitive affective syndrome secondary to cerebellar atrophy. We report the case of an older woman with early-onset (age 45) signs and symptoms of this syndrome, including impairment of executive functions and visuospatial cognition, personality changes, and language deficits, who was followed at a geriatric medical center for 14 years. Neuropsychological, imaging, and behavioral aspects during this period are discussed in light of scientific evidence. This case report contributes to the scientific literature by describing the progression of the signs and symptoms of cerebellar atrophy over the years, which can help guide medical management and support advice for patients and their families.

A atrofia cerebelar é uma doença rara, desafiadora e com poucas descrições na literatura médica. O prejuízo motor é discreto, mas as alterações comportamentais e de linguagem se destacam, caracterizando a síndrome cognitivo-afetiva cerebelar secundária à atrofia cerebelar. Apresentamos o relato de caso de uma paciente idosa, que apresentou sinais e sintomas dessa síndrome precocemente (aos 45 anos de idade) ­ tais como déficits na função executiva, prejuízo visuoespacial, alterações de personalidade e déficits de linguagem ­ e foi acompanhada em um centro médico geriátrico por um período de 14 anos. Aspectos neuropsicológicos, de imagem e comportamentais durante esse período são comentados à luz das evidências científicas. O caso relatado contribui com a literatura científica ao descrever a evolução dos sinais e sintomas da atrofia cerebelar ao longo dos anos, balizando as condutas médicas e amparando as orientações ao paciente e seus familiares.

Long-Term Neurophysiological Outcomes in Patients Undergoing Coronary Artery Bypass Grafting

Abstract Introduction: This study aims to evaluate late postoperative neurophysiological outcomes in patients after coronary artery bypass grafting (CABG). Methods: Forty-five male patients with stable coronary artery disease aged 45-69 years underwent extended neuropsychological assessment using the software Status PF and electroencephalographical examination 3-5 days before CABG and 5-7 years after CABG. Postoperative decline in cognitive functions was determined by a 20% decrease in the cognitive indicator compared to that at baseline on 20% of the tests included in the Status PF battery. Statistical analysis was performed using the software STATISTICA 10.0. Multiple regression was used to identify demographic, clinical, and electroencephalographical variables associated with adverse cognitive outcomes. Results: Cognitive decline was observed in 54% of the patients in the long-term postoperative period. Five to seven years after CABG, all patients have shown an increase in the theta rhythm power compared to the preoperative values, which is most pronounced in the frontal and temporal areas of the right hemisphere (P=0.04), along with a decrease in the alpha rhythm in the posterior areas of the cortex (P=0.005). Multiple regression has reported that the main predictors of cognitive impairment are slower mean alpha frequency, decreased theta-2 rhythm with eyes closed in the right temporal area, and increased theta-2 rhythm with eyes open in the left temporal area (F(5.39)=8.81; P<0.00007; adjusted R-squared=0.57). Conclusion: Our findings indicate that 54% of the patients suffer from postoperative cognitive decline associated with increased theta and decreased alpha rhythms 5-7 years after CABG.

Cognitive Assessment in Patients with Traumatic Brain Injury

Traumatic brain injury (TBI) is a major public health problem inWestern countries. ATBI brings many negative consequences, including behavioral and cognitive changes, which affect social adjustment and the performance of functional activities. Cognitive evaluation after TBI is a complex issue in what pertains to definition of the most appropriate questionnaires for clinical use in a comprehensive analysis of the condition of the patient. In this paper, we described a critical review of the main cognitive assessment tests currently used in clinical and research settings in patients with TBI.

Severe Dizziness Related to Postural Instability, Changes in Gait and Cognitive Skills in Patients with Chronic Peripheral Vestibulopathy

Abstract Introduction Peripheral vestibular disorders can lead to cognitive deficits and are more common in elderly patients. Objective To evaluate and correlate cognitive, balance and gait aspects in elderly women with chronic peripheral vestibular dizziness, and to compare them with elderly women without vestibular disorders. Methods Twenty-two women presenting peripheral vestibular dizziness episodes for at least six months participated in the study. The individuals were categorized by dizziness severity level: moderate (n = 11) or severe (n = 11). The control group (n = 11) included women showing no vestibulopathy, light-headedness or dizziness. Cognitive assessments and semi-static and dynamic balance assessments were performed with the Balance Master (Neurocom International, Inc., Clackamas, OR), while the Dizziness Handicap Inventory provided a score for the severity of the symptoms. The groups were submitted to statistics of inference and correlation between cognitive, balance and stability variables. Results The group with severe dizziness showed higher sway speed of the center of pressure in the anteroposterior direction, smaller step length, and slower gait than the control group. Regarding the cognitive variables, the group with severe dizziness symptoms presented significant correlations with stability and gait variables. Conclusion The relationship between cognitive aspects, balance and gait was stronger in women with severe dizziness than in those with no vestibulopathy.

RESUMO As cardiopatias congênitas (CC) estão entre as principais causas de morbimortalidade na primeira infância e os lactentes com essa condição podem apresentar atrasos no desenvolvimento neuropsicomotor (DNPM). O objetivo deste estudo foi avaliar a influência da CC no DNPM de lactentes. Trata-se de um estudo observacional com avaliação do desenvolvimento neuropsicomotor realizada pela Bayley Scales of Infant and Toddler Development (BSID-III). As condições maternas e clínicas dos lactentes foram verificadas no relatório de alta médica e na caderneta de saúde da criança, e a condição socioeconômica das famílias pelo Critério da Classificação Econômica Brasil. Para associar as variáveis clínicas e o DNPM foram utilizados o coeficiente de correlação de Spearman e o teste de razão de verossimilhança. Foram avaliados 18 lactentes, com predomínio do sexo feminino (72,2%). A maioria das mães (47,1%) possuía ensino médio completo ou superior incompleto, com média da idade de 27,2±5,5 anos. Houve correlação das escalas do BSID-III com as variáveis quantitativas analisadas: escala motora com o peso (p=0,02 e r=0,54) e com uso de oxigenoterapia (p=0,009 e r=−0,591); já para as variáveis qualitativas as associações foram entre: escala motora e condição socioeconômica (p=0,015), escala motora e comunicação interatrial - (CIA) (p=0,023) e escala da linguagem e CIA (p=0,038). A CC influenciou o DNPM, principalmente no aspecto motor. Além disso peso, diagnóstico de CIA, uso de oxigenoterapia e condição socioeconômica foram considerados como principais fatores de risco para o atraso no DNPM.

ABSTRACT Congenital heart defects (CHD) are among the main causes of morbidity and mortality in infants who has this impairment may present delays in neuropsychomotor development (NPMD). This study assesses the influence of CHD on NPMD of infants. This is an observational study assessing neuropsychomotor development performed by Bayley Scales of Infant and Toddler Development - BSID-III. The Brazilian Economic Classification Criteria was used to verify the socioeconomic status of the families and also the maternal and infants' clinical conditions were verified in the medical discharge report and in the child's health handbook. For the association between the quantitative and qualitative variables with the NPMD, the Spearman's correlation coefficient and the likelihood ratio test were used. A total of 18 infants were assessed, with a predominance of females (72.2%). Most mothers (47.1%) had complete high school or incomplete higher education, with a mean age of 27.2±5.5 years. There was a correlation between the BSID-III scales and the quantitative variables analyzed: motor scale with weight (p=0.02 and r=0.54) and oxygen therapy (p=0.009 and r=−0.591); besides that, the qualitative variables correlation were: motor scale and socioeconomic condition (p=0.015), motor scale and Interatrial Communication - IAC (p=0.023) and language with IAC scales (p=0.038). CHD influences the delay of NPMD, mainly for motor aspect. Furthermore, weight, diagnosis of IAC, use of oxygen therapy and socioeconomic status were considered the main risk factors for the delay in NPMD.

Neuroprotective effect of low mean arterial pressure on postoperative cognitive deficit attenuated by prolonged coronary artery bypass time: a meta-analysis

Abstract Introduction: The true influence of the low mean arterial pressure (low MAP) during coronary artery bypass grafting (CABG) on the development of postoperative cognitive deficit (POCD) remains controversial. We aimed to perform a meta-analysis and meta-regression to determine the effect of low MAP on POCD, as well as moderator variables between low MAP and POCD. Methods: The Web of Science, PubMed database, Scopus and the Cochrane Library database (up to June 2018) were searched and retrieved articles systematically reviewed. Only randomized controlled trials (RCTs) comparing maintenance of low MAP (<80 mmHg) and high MAP (>80 mmHg) during cardiopulmonary bypass (CPB) were included in our final review. Statistical analysis of the risk ratio (RR) and corresponding 95% confidence interval (CI) was used to report the overall effect. The overall effect and meta-regression analysis were done using Mantel-Haenszel risk ratio (MHRR) and the corresponding 95% confidence interval (CI). Results: A total of 731 patients in three RCTs were included in this study. POCD occurred in 6.4% of all cases. Maintenance of low MAP did not reduce the occurrence of POCD (MHRR 1.012 [95% CI 0.277-3.688]; Z=0.018; P=0.986; I2=66%). Shorter CPB time reduced the occurrence of POCD regardless of group assignment (MH log risk ratio -0.519 [95% CI -0.949 - -0.089]; Z= -2.367; P=0.017). Conclusion: POCD is a common event among CABG patients. The neuroprotective effect of low MAP on POCD was attenuated by the prolonged CPB time.

Sensitivity and specificity of the Brazilian version of the Montreal Cognitive Assessment - Basic (MoCA-B) in chronic kidney disease / Sensibilidade e especificidade da versão brasileira do Montreal Cognitive Assessment - Basic (MoCA-B) na doença renal crônica

Abstract Introduction Cognitive impairment in chronic kidney disease (CKD) is commonly associated with neuropsychiatric disorders. As a complex pathology, at all stages of CKD patients need to have a good understanding of the need for drug and nutritional adherence. Cognitive screening is the starting point for detection of cognitive impairments. Objective To determine the specificity and sensitivity of the Brazilian Portuguese version of the Montreal Cognitive Assessment - Basic (MoCA-B) for identification of cognitive impairment in the CKD population. Methods This was a cross-sectional study with 163 CKD patients undergoing hemodialysis treatment. The Mini-Mental State Examination (MMSE) and MoCA-B were administered. Results The MoCA-B has reliable internal consistency (Cronbach's alpha = 0.74). A cutoff point of ≤ 21 points provides the best sensitivity and specificity for detection of cognitive impairment. The education variable had less impact on the total MoCA-B score than on the total MMSE score. Conclusions The MoCA-B is a suitable screening instrument for evaluating the global cognition of hemodialysis patients. The results can help health professionals to conduct evaluations and plan clinical management.

Resumo Introdução O comprometimento cognitivo na doença renal crônica (DRC) é comumente associado a distúrbios neuropsiquiátricos. Sendo uma patologia complexa, a DRC, em qualquer estágio, requer que o paciente tenha uma boa compreensão da necessidade de adesão ao medicamento e à nutrição. A triagem cognitiva é o ponto de partida para a detecção de deficiências cognitivas. Objetivo Determinar a especificidade e a sensibilidade da versão em português do Brasil do Montreal Cognitive Assessment - Basic (MoCA-B) para identificação de comprometimento cognitivo na população com DRC. Métodos Este foi um estudo transversal com 163 pacientes com DRC em tratamento hemodialítico. Foram aplicados o Mini Exame do Estado Mental (MEEM) e o MoCA-B. Resultados O MoCA-B obteve consistência interna confiável (alfa de Cronbach = 0,74). Um ponto de corte de ≤ 21 pontos fornece a melhor sensibilidade e especificidade para a detecção de comprometimento cognitivo. A variável educação teve menos impacto no escore total do MoCA-B do que no escore total do MEEM. Conclusões O MoCA-B é um instrumento de triagem adequado para avaliar a cognição global de pacientes em hemodiálise. Os resultados podem ajudar os profissionais de saúde a realizar avaliações e planejar o manejo clínico.

Cognitive profile of children with sickle cell anemia compared to healthy controls / Perfil cognitivo de crianças com anemia falciforme, comparado com o de controles sadios

Abstract Objective: To evaluate the cognitive abilities of children and adolescents with sickle cell anemia diagnosed through neonatal screening and to compare them with healthy controls, adjusting the results to their socioeconomic status. Methods: Cognitive assessment was performed with the Wechsler WISC-III scale in 64 children and adolescents with sickle cell anemia and in 64 controls matched by gender and age, without the disease and without neurological impairment; socioeconomic status was measured by the Criterion Brasil. Results: All cognitive scores were lower in the group of patients. The mean overall IQ, Verbal IQ, and Performance IQ were, respectively, 90.95 for the group of patients and 113.97 for the controls (p < 0.001); 91.41 for the group of patients and 112.31 for the controls (p < 0.001); 92.34 for the group of patients and 113.38 for the controls (p < 0.001). Scores for processing speed, distraction resistance, and perceptual organization were also significantly lower in patients. A direct and significant correlation was detected between socioeconomic status and cognitive scores. In the multivariate analysis, for the same socioeconomic status, a child with sickle cell anemia had an average IQ of 21.2 points lower than the mean IQ observed for the controls (p < 0.001), indicating that the disease, adjusted for the socioeconomic effect, is a strong predictor of the overall IQ. Conclusion: The cognitive impairment of children with sickle cell anemia is severe and manifests even when the disease effect is adjusted to the socioeconomic status. In the authors' view, such impairment requires an early preventive approach in order to avoid this cognitive damage.

Resumo Objetivo: Avaliar os sistemas cognitivos de crianças e adolescentes com anemia falciforme provenientes de triagem neonatal e compará-las com controles sadios, ajustando-se os resultados para o nível socioeconômico. Método: A avaliação cognitiva foi feita com a escala de Wechsler WISC-III em 64 crianças e adolescentes com anemia falciforme e em 64 controles pareados por sexo e idade, sem a doença e sem comprometimento neurológico; o nível socioeconômico foi aferido pelo Critério Brasil. Resultados: Todos os escores cognitivos foram inferiores no grupo de pacientes. As médias de QI Total, QI Verbal e QI de Execução foram respectivamente 90,95 para o grupo de pacientes e 113,97 para os controles (p < 0,001); 91,41 para o grupo de pacientes e 112,31 para os controles (p < 0,001); 92,34 para o grupo de pacientes e 113,38 para os controles (p < 0,001). Os escores de velocidade de processamento, de resistência à distração e de organização perceptual foram, também, significativamente mais baixos nos pacientes. Detectou-se correlação direta e significativa entre o nível socioeconômico e os escores cognitivos. Em análise multivariada, para um mesmo nível socioeconômico, uma criança com anemia falciforme teve QI total, em média, 21,2 pontos mais baixo do que a média dos controles (p < 0,001), indicou que a doença, ajustada para o efeito socioeconômico, é forte fator preditivo do QI total. Conclusão: Os prejuízos cognitivos das crianças com anemia falciforme são intensos e se manifestam mesmo quando o efeito da doença é ajustado para o nível socioeconômico, o que, a nosso ver, requer abordagem preventiva precoce para tentar evitar tais prejuízos.

Un caso de síndrome de embolia grasa: tratamiento y rehabilitación neurológica y cognitiva / A case report off at embolism syndrome: Treatment and neurological and cognitive rehabilitation

Resumen Se reporta el proceso de recuperación y rehabilitación neurológica y cognitiva de una mujer joven que desarrolló un síndrome de embolia grasa con repercusiones neurológicas, después de sufrir un politraumatismo. La paciente era una mujer de 21 años de edad con fractura cerrada de húmero y fémur izquierdos, que presentó un síndrome de embolia grasa, neumotórax izquierdo e hipertensión pulmonar, en las primeras 24 horas después de un accidente. Estuvo hospitalizada un mes y quedó con varios déficits neurológicos centrales, como infartos 'lacunares' y necrosis cortical laminar occipital, así como limitaciones en la bipedestación, la marcha, la visión y las funciones cognitivas. A partir del primer mes después del alta hospitalaria, se comenzó un proceso integral de rehabilitación neurológica y cognitiva en casa, y posteriormente, en una unidad médica de rehabilitación. Durante los primeros dos años después del accidente, la paciente recibió estimulación sensorial, sensoperceptiva y motora, así como rehabilitación motora y visual intensiva. Una vez se recuperó físicamente, se inició un proceso de rehabilitación neuropsicológica. Seis años después del accidente, la paciente terminó sus estudios universitarios y hoy está laboralmente activa. El proceso de rehabilitación neurológica es complejo, individual y difícil, aunque no imposible, y no se puede estandarizar un patrón de recuperación para todos los pacientes. Si bien existe la recuperación espontánea, la cual se da en los primeros seis meses, el caso aquí reportado demuestra que, en la fase crónica, la recuperación se puede lograr, pero requiere de evaluaciones y técnicas coordinadas de rehabilitación neurológica.

Abstract We report the neurological and cognitive recovery and rehabilitation process in a young woman who developed a fat embolism syndrome with neurological repercussions secondary to multiple trauma. The patient was a 21-year-old woman with a closed fracture of the left humerus and femur. She developed fat embolism syndrome, left pneumothorax and pulmonary hypertension in the first 24 hours after the accident. After one month of hospitalization, the patient had several central neurological deficits such as lacunar infarcts and occipital laminar cortical necrosis, as well as limitations in standing, walking, vision, and cognitive functions. An integral process of neurological and cognitive rehabilitation--first at home and later in a medical rehabilitation unit-- was carried out from the first month after being released from the hospital. During the first two years after the accident, the patient received sensory and motor stimulation, motor rehabilitation, and intensive visual rehabilitation. Once recovered physically, a process of neuropsychological rehabilitation began. Six years after the accident, the patient finished her university studies and she is working actively. The neurological rehabilitation process is complex, individual and difficult, but not impossible, and a recovery pattern cannot be standardized for all patients. Although there is spontaneous recovery, which occurs in the first six months, the case here reported shows that in the chronic phase recovery can be achieved but requires evaluations and coordinated techniques of neurological rehabilitation.

Perfil neuropsicológico y efectos de la rehabilitación cognitiva en la leucemia linfoblástica aguda: a propósito de un caso / Neuropsychological profile and cognitive rehabilitation training effects on acute lymphoblastic leukaemia: a case study

La Leucemia Linfoblástica Aguda (LLA) infantil es el cáncer pediátrico más frecuente. Actualmente cuenta con un alto porcentaje de supervivencia, pero dichos pacientes presentan secuelas cognitivas secundarias a la enfermedad debidas, principalmente, al tratamiento médico recibido para evitar la recidiva del cáncer. Por lo tanto, resulta necesaria la implementación de programas de rehabilitación cognitiva específicos para este tipo de población. Es por ello que el objetivo del presente estudio fue describir los déficits cognitivos en un varón de 17 años que fue diagnosticado con LLA a los 9 años. Tras la valoración neuropsicológica inicial se desarrolló un programa de rehabilitación cognitiva intensivo durante dos años consecutivos. Realizamos un estudio pre-post en el que administramos el Conners Continuous Performance Test (CPT-II) y la Escala de Inteligencia de Wechsler para niños (WISC-IV). Los resultados, antes de la intervención, mostraron que el paciente manifestaba una menor velocidad de procesamiento y dificultades de atención sostenida y alternante, comprensión verbal y razonamiento perceptivo. Además, también presentó un número considerable de errores perseverativos, signo de dificultades de flexibilidad cognitiva y control inhibitorio. Dichos déficits mejoraron notablemente tras el programa de rehabilitación cognitiva. En conclusión, nuestro estudio pone de manifiesto la necesidad de aplicar programas de rehabilitación cognitiva tempranos para paliar las secuelas cognitivas derivadas de la LLA y de su tratamiento médico, así como mejorar la calidad de vida del paciente, ya que las mejoras cognitivas redundarán en su rendimiento académico y en su funcionamiento cotidiano.

Childhood Acute Lymphoblastic Leukemia (ALL) is the most common pediatric cancer. It currently has a high survival rate, but these patients have cognitive sequelae secondary to the disease, mainly due to the medical treatment received to prevent cancer recurrence. Therefore, it is necessary to implement specific cognitive rehabilitation programs for this type of population. Hence, the main objective of this study was to describe cognitive deficits in a 17-year-old male who was diagnosed with ALL when he was 9 years old. After the initial neuropsychological evaluation, an intensive cognitive rehabilitation program was developed during two consecutive years. We conducted a pre-post study in which we administered the Conners Continuous Performance Test (CPT-II) and the Wechsler Intelligence Scale for Children (WISC-IV). Results, before the intervention, showed that the patient presented a lower processing speed and difficulties of sustained and alternating attention, verbal comprehension and perceptive reasoning; in addition to a large number of perseverative errors, sign of self-monitoring difficulties and inhibitory control. These deficits improved markedly after a program of cognitive rehabilitation. In conclusion, our study highlights the need to apply early cognitive rehabilitation programs to alleviate the cognitive sequelae derived from ALL and its medical treatment. In addition, any improvement in their cognitive capabilities will have a positive impact in their academic performance and quality of life.

Determinantes del estado de salud de la población y su influencia en el desarrollo de los trastornos cognitivos / Determinants of the health status of the population and its influence on the development of cognitive disorders

Introducción: Ante el envejecimiento acelerado de la población cubana los trastornos cognitivos se han convertido en creciente problema y un reto para nuestro sistema de salud. Objetivo: Describir la influencia de las determinantes del estado de salud de la población en el desarrollo de los trastornos cognitivos. Fuente de datos: Se consultaron 113 artículos en la Biblioteca Virtual Scielo y en las bases de datos Medline, Google Scholar, Cochrane y PubMed, en idioma Inglés y Español. Se seleccionaron 40, publicados en revistas nacionales e internacionales de gran impacto, por autores considerados expertos en esta temática. Síntesis de los datos: Además de factores biológicos y genéticos, existen determinantes psicosociales como el nivel educacional y los estilos de vida que pudieran incidir en la aparición y desarrollo de las demencias. Entre estos últimos, aparecen los hábitos tóxicos, las relaciones sociales, antecedentes de depresión, nivel socioeconómico y otros. Conclusiones: La influencia de los determinantes del estado de salud de la población en el desarrollo de los trastornos cognitivos, es notable. Es necesario el estudio de estos determinantes y su contribución a la puesta en marcha de estrategias de intervención comunitaria que ayuden, sobre todo, a la población más vulnerable a tener una mejor calidad de vida(AU).

Introduction: The accelerated aging of the Cuban population is an alert to the high prevalence of dementias and other chronic diseases. Objective: To describe the influence of health status determinants of the population in the development of cognitive disorders. Data source: 113 articles in the Scielo Virtual Library and in Medline, Google Scholar, Cochrane and PubMed databases were consulted, both in English and Spanish. 38 of the selected were published in national and international magazines of great impact, by authors considered experts in this subject. Synthesis of data: In addition to biological and genetic factors, there are other psychosocial determinants such as education and lifestyles that may have an impact on the onset and development of dementia. Among the latter are toxic habits, social interactions, sleep, and depressive states. These states may be considered as a psychological reaction to incipient cognitive worsening or as an early manifestation of dementia. Conclusions: The influence of population´s health status determinants in the development of cognitive disorders is remarkable. Given the accelerated aging of the Cuban population, cognitive disorders become a growing health problem. More research is needed and the results of this may contribute to a better understanding of the epidemiological behavior of these disorders. It is necessary, through intersectoral work, the implementation of community intervention strategies that help above all most vulnerable population to have a better life quality(AU)

Caracterização das afasias na hemorragia subaracnóidea aneurismática / Characterization of aphasia in aneurysmal subarachnoid hemorrhage

RESUMO Objetivo Caracterizar o perfil dos quadros afásicos determinados pela hemorragia subaracnóidea aneurismática (HSA) da artéria cerebral média esquerda. Método Estudo analítico, retrospectivo, transversal, tendo como banco de dados as avaliações cognitivas de 193 pacientes do Hospital da Restauração com HSA aneurismática no período de março de 2007 a novembro de 2009. Destes, foram selecionados 26 pacientes com HSA em território da ACM-E, confirmada por angiografia digital. Os quadros afásicos foram classificados através do desempenho da linguagem dos pacientes através do Protocolo Montreal Toulose - Versão Alpha e a tarefa de fluência verbal da bateria CERAD. A pesquisa foi realizada no período de junho a agosto de 2015. Resultados Foi identificado comprometimento da linguagem e fluência verbal nos pacientes com HSA em território de ACM-E quando comparados com a população controle (50 indivíduos). Dos 26 pacientes com HSA, 11 apresentaram quadros afásicos ainda no período pré-operatório. Conclusão Os resultados da pesquisa corroboram com a literatura, mostrando que o quadro da HSA promove comprometimentos cognitivos ainda na fase pré-operatória para oclusão de aneurisma. Tendo em vista os aspectos observados, os quadros afásicos predominantes caracterizam afasia de compreensão por sequelas nas áreas cerebrais posteriores.

ABSTRACT Purpose Characterize the profile of aphasic syndromes determined by aneurysmal subarachnoid hemorrhage (aSAH) of the left middle cerebral artery (LMCA). Methods An analytical, retrospective, cross-sectional study was conducted using a database of cognitive assessments of 193 patients with aSAH admitted to Hospital da Restauração between March 2007 and November 2009. Of these, a total of 26 patients with aSAH in the LMCA territory confirmed by digital angiography were selected. Aphasia was assessed through the Montreal-Toulouse Language Assessment Alpha Version Protocol (Alpha Version) and the CERAD Neuropsychological Test Battery (Verbal fluency). Results Language and verbal fluency impairments were identified in patients with aSAH in the LMCA territory when compared with the control population (50 individuals). Of the 26 patients with aSAH, 11 presented aphasic characteristics preoperatively. Conclusion The results of this research corroborate the literature, showing that the aSAH frame causes cognitive impairments even in the preoperative phase for aneurysm occlusion. Considering the observed aspects, the predominant aphasic syndromes characterize comprehension aphasia due to sequels in the posterior cerebral artery territory.

Potential role of a cognitive rehabilitation program following left temporal lobe epilepsy surgery / Reabilitação neuropsicológica em pacientes com epilepsia submetidos à lobectomia temporal dominante

ABSTRACT Research into memory and epilepsy has focused on measuring problems and exploring causes with limited attention directed at the role of neuropsychological rehabilitation in alleviating post-operative memory difficulties. Objectives To assess the effects of a memory rehabilitation program in patients with left temporal lobe epilepsy following surgery. Methods Twenty-four patients agreed to participate and 18 completed the study; nine received memory rehabilitation while nine had no input and were designated as controls. Verbal learning efficiency, naming abilities, memory subjective ratings, ecological activity measures and a language fMRI paradigm were used as outcome measures. Results Improved verbal learning and naming test performance, increase in memory strategy use and improved self-perception were observed following the rehabilitation. Changes in fMRI activation patterns were seen in the rehabilitation group over the long term. Conclusion The findings support the potential role of a cognitive rehabilitation program following left temporal lobe surgery.

RESUMO As publicações na área de epilepsia e memória se focam em mensurar prejuízos e investigar causas, com poucos dados sobre reabilitação neuropsicológica em pacientes pós-cirúrgicos. Objetivos Avaliar os efeitos da reabilitação neuropsicológica em pacientes submetidos a lobectomia temporal dominante. Métodos Vinte e quatro pacientes iniciaram o estudo, apenas dezoito o concluíram, dos quais 9 foram participantes de sessões de reabilitação com enfoque em memória. Todos os participantes foram avaliados quanto a autopercepção de dificuldades de memória; ao uso de estratégias para minimizar tais dificuldades; a habilidade de nomeação e a aprendizagem verbal e foram submetidos à ressonância magnética funcional. Resultados Foi encontrado efeito significativo da reabilitação neuropsicológica na autopercepção de dificuldades de memória; no uso de estratégias compensatórias; na aprendizagem verbal e na nomeação. Alterações no padrão de ativação na RMf foram observadas no grupo submetido a reabilitação. Conclusão A reabilitação neuropsicológica pode beneficiar pacientes submetidos a lobectomia temporal antero-mesial dominante com prejuízos de memória.

Benign multiple sclerosis: aspects of cognition and neuroimaging / A esclerose múltipla benigna: aspectos cognitivos e de neuroimagem

ABSTRACT The existence of a benign multiple sclerosis (BMS) form is a controversial subject. Recent studies of these patients reveal different levels of cognitive impairment, despite the apparent preservation of motor function. The objective of this study was to review and analyze a number of publications that discuss the general aspects of this disease form, such as the definition criteria, prevalence, and clinical and neuroimaging markers. A systematic review of published data on BMS up to October 2015 was performed. Thirty-one published articles were analyzed. The estimated frequency of BMS varied between 6% and 73%. Cognitive impairment was recognized as affecting 17% to 47% of the subjects and presented significant correlation with neuroimaging, such as brain atrophy, increased lesion volume in T2 magnetic resonance assay, and regional grey matter atrophy. The current criteria overestimated the frequency of BMS and, for that reason, this highlights the importance of validating the diagnostic methods practiced.

RESUMO A existência real de uma forma benigna da esclerose múltipla (EMB) é um tema controverso. Ampliar o número de publicações que abordam os aspectos gerais do subtipo da doença, tais como os critérios de definição utilizados, análise de prevalência e da presença de marcadores clínicos e de neuroimagem. Foi realizada uma revisão sistemática dos dados publicados até outubro de 2015, relativa à EMB. Os dados encontrados foram dicotomizados em gráficos e, posteriormente, analisados. Foram analisados 31 artigos publicados. A frequência estimada EMB oscila entre 6% a 73%. O comprometimento cognitivo foi reconhecido em 17–47% dos sujeitos, apresentando correlação significativa com os aspectos de neuroimagem, como a atrofia cerebral global, aumento do volume lesional em T2 e atrofia regional da substância cinzenta. Os critérios atualmente utilizados superestimam a freqüência de EMB, e, por essa razão, destaca-se a importância da validação dos métodos de diagnóstico praticados.

Una revisión de la literatura acerca de las características neuropsicológicas de niños con craneosinostosis simple en diferentes edades / A review of the literature on the neuropsychological characteristics of children with single suture craniosynostosis at different ages

Introduction: Single suture craniosynostosis is the premature closure of one or more cranial sutures. It leads to abnormal skull growth and in some cases to structural and/or functional brain abnormalities. If these anomalies cause a psychomotor development lag and/or cognitive impairment is a controversial topic. This study aims to review the main findings related to psychomotor development and cognitive functioning in children with craniosynostosis, from birth to school age, dividing them into three stages: birth to 3 years, preschool and school. Method: An electronic search was made in PubMed from 2000 to 2015, using the following keywords: "craniosynostosis and neurodevelopment", "craniosynostosis and neuropsychological", "craniosynostosis and cognition". Results: In the early stage of life some children with craniosynostosis can have motor, language and cognition deficits; these impairments are also present in a variable percentage of preschool children, in some cases accompanied with behavior disorders; deficits in attention, executive functions and learning disorders, are reported in school years. Conclusion: Some neuropsychological alterations are found in a variable proportion of patients with craniosynostosis in all stages of development whichare revealed depending on the demands of each age. It is difficult to draw a cognitive profile for this population because of the heterogeneity related to characteristics of the sample, time of assessment, functions assessed and instrument used. It is important to make longitudinal neuropsychological assessments to know how children with craniosynostosis are developing in late stages and to develop consensus about cognitive functions and assessment instruments appropriate for each age.

Introducción: La craneosinostosis simple es el cierre prematuro de una o más suturas craneales que provoca crecimiento anormal del cráneo y en algunos casos anormalidades cerebrales estructurales y/o funcionales. Es un tema controversial si estas anormalidades causan el retraso psicomotor y/o cognitivo reportado en estos pacientes. Esta revisión tiene como objetivo abordar los hallazgos encontrados en el desarrollo psicomotor y cognitivo en niños con craneosinostosis, desde el nacimiento hasta la edad escolar, dividiéndolos en tres etapas: nacimiento a 3 años, etapa preescolar y escolar. Método: Se realizó una búsqueda en PubMed del 2000 al 2015, utilizando estas palabras claves: "craniosynostosis and neurodevelopment", "craniosynostosis and neuropsychological", "Craniosynostosis and cognition". Resultados: En las etapas tempranas de la infancia, los niños con craneosinostosis pueden tener deficiencias motoras, de lenguaje y cognitivas; estos déficits están presentes en un porcentaje variable en la etapa preescolar y pueden acompañarse de alteraciones conductuales; deficiencias atencionales, ejecutivas y de aprendizaje, se reportan en la edad escolar. Conclusión: Se reportan alteraciones neuropsicológicas en un porcentaje variable en estos pacientes en todas las etapas del desarrollo, que se van manifestando conforme las demandas del ambiente. Es difícil establecer un perfil neuropsicológico debido a la heterogeneidad de las características de las muestras en los estudios, el tiempo de la evaluación, las funciones estudiadas y los instrumentos utilizados. Es importante realizar un seguimiento longitudinal para conocer el desarrollo de estos niños, así como el hacer un consenso sobre las funciones cognitivas a evaluar e instrumentos a utilizar para cada edad.

Rendimiento neuropsicológico en pacientes con miastenia gravis / Rendimiento neuropsicológico en pacientes con miastenia gravis

La miastenia gravis es una enfermedad crónica, autoinmune que afecta la transmisión neuromuscular. Se han comunicado hallazgos contradictorios acerca del deterioro cognitivo en dicha enfermedad. El objetivo del presente estudio fue investigar el patrón cognitivo de pacientes con miastenia gravis. Participaron 24 pacientes con miastenia gravis, anticuerpos anti-receptor de acetilcolina (ACRA) positivos, y 24 controles. Pacientes: edad 43.9 ± 14.8, años de escolaridad 10.9 ± 3.3. Controles: edad 44.5 ± 15.4, años de escolaridad 11.5 ± 3.3. Se evaluaron las siguientes áreas: memoria verbal: (largo plazo almacenamiento, recuperación y recuerdo diferido) del test selectivo de memoria; atención: Paced Auditory Serial Addition Task (PASAT, 2 y 3 segundos); funciones ejecutivas (FE): analogías y secuencia números-letras. Se administró además el Inventario de Depresión de Beck II (IDB II). El 33.3% de los pacientes obtuvo un desempeño anómalo en dos o más test cognitivos. El 37.5% mostró deterioro en atención; 33.3% en memoria verbal; 29.2% en FE. Se encontraron diferencias significativas entre pacientes y controles en almacenamiento (p = 0.001); recuperación (p = 0.007); recuerdo diferido (p = 0.000); PASAT 3 (p = 0.009); PASAT 2 (p = 0.009); analogías (p = 0.003). Se encontró evidencia de depresión: leve en el 4.2 %; moderada en el 25% y grave en el 29.2%. El rendimiento neuropsicológico declina en los pacientes con miastenia gravis, encontrándose mayor alteración en la atención que en el resto de las áreas cognitivas.

Myasthenia gravis is a chronic autoimmune disease that affects the neuromuscular transmission. Controversial findings had been reported about cognitive impairment in this disease. The aim of this study was to investigate the cognitive pattern of patients with myasthenia gravis. There were enrolled 24 patients with myasthenia gravis, anti-acetylcholine receptor antibodies (ACRA) positive, and 24 healthy controls. Patients: age 43.9 ± 14.8, years of education 10.9 ± 3.3. Controls: age 44.5 ± 15.4, years of education 11.5 ± 3.3. The following areas were evaluated: verbal memory: (long-term storage, retrieval, delayed recall) of the Selective Remained Test; attention: Paced Auditory Serial Addition Task (PASAT 2 and 3 seconds); executive functions: analogies and numbers-letters sequence. Also, it was administered the Beck Depression Inventory II (BDI II). About 33.3% of patients obtained abnormal performance in two or more cognitive tests. 37.5% showed deterioration in attention; 33.3% in verbal memory; 29.2% in executive functions. Significant differences between patients and healthy controls were found in long-term storage (p = 0.001); retrieval (p = 0.007); delayed recall (p = 0.000); PASAT 3 (p = 0.009); PASAT 2 (p = 0.009) and analogies (p = 0.003). Evidence of depression was found: mild in 4.2% of patients; moderate in 25% and severe in 29.2%. Neuropsychological performance declines in patients with myasthenia gravis: attention was more affected than other cognitive areas.
