Comorbid Neurocognitive Impairment in Patients with Epilepsy

Background: Epilepsy is a common chronic non-communicable neurological disorder in which the brain function is impaired. Cognitive function is more frequently impaired in people with epilepsy than in the general population. The neurocognitive outcome of epilepsy in children and adults is vital for social prognosis and quality of life assessment. Cognitive changes in epilepsy have multifactorial etiology, including the epilepsy itself, age at onset, duration of epilepsy, treatment of epilepsy, reaction to epilepsy and any associated brain dysfunction and /or damage. This study was conducted to check association of neurocognitive impairment with the socio-demographic factors and disease associated factors in patients with epilepsy. Methodology: This study was a single centre cross-sectional study in which 96 patients were included. Severity of neurocognitive impairment was measured by Addenbrookes’ Cognitive Examination- R (ACE- R) score. Results: Out of 96 patients, neurocognitive impairment was seen in 23 (23.95%) patients. Conclusions: This study shows that neurocognitive impairment was found to be more when the age at onset of epilepsy was less, when the duration of the illness was more and when frequency of seizure was higher. Conclusion: Neurocognitive impairment is noted in patients with epilepsy and must be treated in the long- term management of epilepsy

Research progress on multicomponent physical exercise for patients with neurocognitive impairment / 浙江大学学报·医学版

Neurocognitive impairment is a group of clinical syndromes characterized by impaired cognitive function and decreased motor ability. Non-pharmacological interventions such as physical exercise have advantages in the treatment of patients with neurocognitive impairment. Multicomponent exercise is a combination of various physical exercises, including strength training, endurance training, balance training and flexibility training, that can improve gait, balance and cardiopulmonary function by increasing muscle mass, strength and endurance in people with neurocognitive impairment, while also reducing the risk of falls in elders. This article reviews the benefits of multicomponent exercise for patients with neurocognitive impairment and its evaluation methods; also describes 4 intervention programs and their clinical application, to provide evidence for clinical practice and promote the application of multicomponent exercise in patients with neurocognitive impairment.

Sintomatología depresiva y trastornos neurocognitivos en pacientes con VIH adherentes y no adherentes a TARAA: estudio transversal analítico / Depressive symptomatology and neurocognitive disorders in haart-adherent and non-adherent hiv patients: a cross-sectional analytical study

Introducción: Las personas portadoras del virus de inmunodeficiencia humana (VIH) presentan mayor comorbilidad de trastornos neurocognitivos y del ánimo que la población general. La introducción de los antirretrovirales ha disminuido significativamente la demencia asociada a VIH, relacionado a la adherencia a la terapia antirretroviral altamente activa (TARAA). Diversos estudios han demostrado la coexistencia de otros factores para explicar dicho trastorno cognitivo, tales como enfermedad neurológica previa, enfermedad psiquiátrica, consumo de drogas, nivel educativo, reserva cognitiva, entre otras. Objetivo: Determinar el grado de sintomatología depresiva, deterioro cognitivo y su relación con la adherencia a TARAA y otros factores de curso clínico en pacientes portadores de VIH en control ambulatorio. Métodos: Estudio transversal. Se incluyeron pacientes que viven con VIH adscritos al programa de infectología del Hospital Dr. Gustavo Fricke, Viña del mar, Chile. Se utilizaron datos sociodemográficos, clínicos y se aplicaron las escalas Depression in the Medicaly III Questionary, Montreal Cognitive Assesment y Morysky Green Levin Test. Resultados: Se incluyeron 29 participantes, en su mayoría hombres (86,2%) y con escolaridad técnica o profesional (86.2%). No hubo diferencias entre variables biodemográficas, depresivas ni subdimensiones cognitivos. Entre pacientes adherentes y no adherentes se encontró diferencias significativas respecto a la presencia de algún deterioro cognitivo. Conclusiones: Los resultados deben ser interpretados con cautela, dado su alcance limitado. Futuros estudios traslacionales debieran incorporar mediciones más certeras del nivel de adherencia al TARAA.

Introduction: Human immunodeficiency virus (HIV) carriers present more neurocognitive and mood disorders than the general population. The introduction of antiretrovirals has significantly lowered the incidence of HIV associated dementia, and this is related to adherence to highly active antiretroviral therapy (HAART). Several studies have shown the coexistence of other factors that could explain the cognitive disorder, such as a pre-existing neurological disease, psychiatric disease, drug consumption, level of education, cognitive reserve, and others. Objective: To determine the degree of depressive symptomatology and cognitive impairment and their relation to adherence to HAART and other factors of the clinical course of HIV carriers in outpatient supervision. Methods: Cross-sectional study. We included HIV patients in the infectious diseases program, Dr Gustavo Fricke Hospital, Viña del Mar, Chile. We used sociodemographic and clinical data and we applied the Depression in the Medically Ill questionnaire, Montreal Cognitive Assessment, and the Morysky Green Levin Test. Results: 29 patients participated, mainly men (86.2%) with technical or professional education (86.2%). There were no significant differences in sociodemographic, depressive, or cognitive subdomain variables. There were significant differences in cognitive impairment between adherents and non-adherents. Conclusions: Care should be taken with interpreting the results, given their limited scope. Future cross-sectional studies should incorporate more accurate measurements of HAART adherence.

The Relationship between Cognition and Asymmetric Dimethyl Arginine, Symmetric Dimethyl Arginine, Nitric Oxide Levels and Total Antioxidant Capacity in Euthymic Bipolar Disorder Patients

ABSTRACT Objective: This study investigates the relationship between serum nitric oxide, asymmetrical dimethylarginine and symmetrical dimethylarginine levels and Total Antioxidant Capacity, and cognitive function in patients with bipolar disorder. Method: The study included 42 bipolar patients, diagnosed and assessed according to the DSM-V criteria, and 30 healthy controls. The Sociodemographic Questionnaire was used for the collection of data, and a bivariate Pearson correlation analysis was carried out. Results: The patient scores from a Rey Auditory Verbal Learning Test (RAVLT), Auditory Consonant Trigram (ACT), Digit Span Test (DST), Wisconsin Card Sorting Test (WCST), Trail Making-B (TMT-B) and Stroop Tests (ST) were found to be impaired in patients with BD when compared to the healthy controls. The SDMA level of the patient group was significantly higher in the control group, while the ADMA level was lower. The SDMA value was found to be positively correlated with ST-1,2,5 duration; and the NO value was positively correlated with ST-3 duration. Conclusions: The presence of neurobiological markers may serve to predict the severity of neurocognitive deficits, and can provide information about the progress of the disease.

Memory impairment: an intermediate clinical syndrome symptom in HTLV-1-infected patients? / Comprometimento da memória: um sintoma de síndrome clínica intermediária em pacientes infectados pelo HTLV-1?

Background Although classical human T-cell lymphocyte virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis syndrome is the most frequent HTLV-1-associated neurological disorder, some "minor" neurological disorders can be seen in "asymptomatic" carriers. These disorders, including cognitive alterations already described in clinical cases and studies, may constitute an intermediate syndrome (IMS) between the asymptomatic state and myelopathy. The aim of this study was to investigate the presence of cognitive deficits in patients with HTLV-1 virus, who usually are diagnosed as asymptomatic. Methods A total of 54 HTLV-1-infected patients were evaluated, 35 asymptomatic and 19 with minor neurological alterations (evaluated by a neurologist); 25 HTLV-1-seronegative individuals served as controls. The instruments used were: Beck's Depression Inventory, Lawton's Daily Life Activity Scale, and a complete neuropsychological battery. The application of these evaluation instruments was performed blindly, with the evaluator neuropsychologist not knowing the clinical condition of the patient. Results Most of the participants in this cohort, including seronegative controls, were female (n = 57, 72.21%), their mean age was 52.34 years (SD = 14.29) and their average schooling was 9.70 years (SD = 4.11). Discussion Participants classified with IMS had lower gross scores when compared with both the patients classified as asymptomatic and with the control group, and when tested for auditory episodic memory of immediate (p < 0.01), and late (p = 0.01), recall. Conclusion Patients with IMS presented with memory impairment when compared with asymptomatic patients and seronegative individuals; this is one of the symptoms that aids in the classification of the syndrome.

RESUMO Apesar da síndrome de HAM / TSP clássica ser a perturbação neurológica mais atribuída, alguns distúrbios neurológicos denominados "menores" são vistos em portadores "assintomáticos" de HTLV-1. Esses distúrbios, incluindo alterações cognitivas já observadas em descrições de casos clínicos e estudos, podendo constituir uma verdadeira síndrome clínica intermediária (SI) entre o estado assintomático e mielopatia. O objetivo deste estudo foi investigar a presença de déficits cognitivos em pacientes portadores do vírus HTLV-1 diagnosticados classicamente como assintomáticos. Métodos Foram avaliadas 54 pessoas, sendo 35 assintomáticos, 19 com alterações neurológicas menores (avaliados por um neurologista) e 25 HTLV-1 negativo. Os instrumentos utilizados foram: Inventário Beck de Depressão, Escala de Atividades de Vida Diária de Lawton e uma completa bateria neuropsicológica. A aplicação destes instrumentos de avaliação foi realizada de forma cega, ou seja, a avaliadora não sabia a condição clinica do paciente. Resultados A maioria dos participantes era do sexo feminino (n = 57, 72,21%), com idade média de 52.34 anos (DP = 14,29) e escolaridade média de 9.70 anos (DP = 4,11). Discussão Avaliando o desempenho cognitivo nos três grupos, foi possível observar que os participantes classificados com SI, apresentaram menores escores brutos, quando comparados, com os pacientes com classificação assintomática e grupo controle e, em relação à memória episódica auditiva de evocação imediata (p < 0,01) (p = 0,01) e tardia. Conclusão Diante dos resultados foi possível concluir que os pacientes com SI apresentam comprometimento de memória quando comparado com os outros grupos, sendo possível, ser este um dos sintomas para auxiliar na classificação da síndrome.

Caregiver induced Alcohol Dependence in a young child with ADHD – a case report.

A four and a half year old young boy with ADHD (attention-deficit hyperactivity disorder) was brought bysocial worker as a case of child abuse, as he was being sedated by his infirm grandfather, using alcohol, tocontrol hyperactivity. The child underwent deaddiction, treated for hyperactivity and enrolled into variousactivities. Grandfather was also extended therapeutic services. Caregiver was changed and case wasmonitored by social worker. Family was extensively given psycho education, especially regarding childabuse. Discussion of this unusual case is chiefly on ADHD, caregiver burnout, substance abuse and of coursechild abuse – its current state of under-recognition in India, detection and management.

Aging, neurocognitive impairment and adherence to antiretroviral therapy in human immunodeficiency virus-infected individuals

ABSTRACT Background/objective: There is an increasing number of older patients with human immunodeficiency virus infection due to the success of antiretroviral therapy, the improved prognosis and life expectancy of patients, and the higher number of new infections among older individuals. The main objective of the present study was to compare the characteristics of older human immunodeficiency virus patients with those of younger patients. Materials and methods: We conducted a cross-sectional study with human immunodeficiency virus-infected patients who were treated at the Specialized Care Service (Serviço de Assistência Especializada) for human immunodeficiency virus/AIDS in the city of Pelotas, South Brazil. Sociodemographic information as well as data on human immunodeficiency virus infection and treatment were collected. All participants underwent psychiatric and neurocognitive assessments, and their adherence to antiretroviral therapy was evaluated. Results: A total of 392 patients participated in the study, with 114 patients aged 50 years and older. The characteristics showing significant differences between older and younger human immunodeficiency virus-infected patients included race/ethnicity, comorbidities, duration and adherence to antiretroviral therapy, currently undetectable viral load, and cognitive impairment. Compared to younger patients, older patients were at higher risk of exhibiting cognitive impairment [OR 2.28 (95% CI: 1.35-3.82, p = 0.002)] and of having increased adherence to antiretroviral therapy [OR 3.11 (95% CI: 1.67-5.79, p < 0.001)]. Conclusions: The prevalence of neurocognitive impairment remained high in human immunodeficiency virus-infected patients despite antiretroviral therapy. In the present study, the prevalence of this type of impairment was significantly higher in patients aged ≥50 years, most likely due to aging, human immunodeficiency virus infection, and a possible synergistic effect between these factors. Despite this higher prevalence, older patients exhibited higher rates of adherence to antiretroviral therapy and of undetectable human immunodeficiency virus viral load.

Preliminary Study of Neurocognitive Dysfunction in Adult Moyamoya Disease and Improvement after Superficial Temporal Artery-Middle Cerebral Artery Bypass

OBJECTIVE: Moyamoya disease (MMD) is a chronic cerebrovascular occlusive disease of unknown etiology. In addition, the neurocognitive impairment of adults with MMD is infrequently reported and, to date, has not been well described. We attempted to determine both the neurocognitive profile of adult moyamoya disease and whether a superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis can improve the neurocognitive impairment in exhibiting hemodynamic disturbance without stroke. METHODS: From September 2010 through November 2012, 12 patients with angiographically diagnosed MMD underwent STA-MCA anastomosis for hemodynamic impairment. Patients with hypoperfusion and impaired cerebrovascular reserve (CVR) capacity but without evidence of ischemic stroke underwent a cognitive function test, the Seoul Neuropsychological Screening Battery (SNSB). Five patients agreed to undergo a follow-up SNSB test. Data from preoperative and postoperative neurocognitive function tests were compared and analyzed. RESULTS: Five of 12 patients were enrolled. The median age was 45 years (range, 24-55 years). A comparison of preoperative to postoperative status of SNSB, memory domain, especially delayed recall showed significant improvement. Although most of the domains showed improvement after surgery, the results were not statistically significant. CONCLUSION: In our preliminary study, large proportions of adult patients with MMD demonstrate disruption of cognitive function. This suggests the possibility of chronic hypoperfusion as a primary cause of the neurocognitive impairment. When preoperative and postoperative status of cognitive function was compared, memory domain showed remarkable improvement. Although further study is needed, neurocognitive impairment may be an indication for earlier intervention with reperfusion procedures that can improve cognitive function.

Study of Neurocognitive Impairment in Psychotic and Nonpsychotic Depression.

Objective: The theory that psychotic depression is a distinct syndrome is supported by reports of statistically significant differences between psychotic and nonpsychotic depression in presenting features, course and outcome, response to treatment and neurocognitive changes. This study examined differences in performance on different neurocognitive measures between patients with psychotic and nonpsychotic depression and healthy controls. Method: 50 patients with psychotic depression, 50 patients with nonpsychotic depression and 30 healthy controls were administered neuropsychological function test battery. Results: Patient with psychotic depression performed poorly on neurocognitive test than patients with nonpsychotic depression who performed poorly than healthy controls and neurocognitive impairment was present globally in both groups of patients. Conclusion: Psychotic depression is different from nonpsychotic depression and produces more cognitive impairment than nonpsychotic depression.
