ABSTRACT

Introducción: Entre las enfermedades neurodegenerativas se encuentra un grupo de patologías que se caracterizan por un compromiso prominente del lenguaje, denominadas usualmente afasias primarias progresivas, las cuales se subdividen en 3 tipos: variante logopénica, variante semántica y variante no fluente o agramática. Presentación del caso: Paciente con cuadro clínico que inicia a los 65 años, con disminución en la interacción social. Un par de meses después, la esposa nota que el lenguaje del paciente se torna poco fluido, habla con palabras o frases cortas, no logra decir oraciones completas, además de presentar cambios en la entonación de las palabras y alteraciones del lenguaje escrito. El paciente manifiesta que su principal limitación en el momento es el no poder expresar lo que quiere decir, y por este motivo consulta. Discusión: En el caso de este paciente, se describe inicialmente un cambio en su personalidad que no compromete su funcionalidad, sin embargo, al poco tiempo se presenta compromiso del lenguaje como síntoma prominente y que genera mayor compromiso en su calidad de vida, con pruebas neuropsicológicas y hallazgos de neuroimagen que apoyan el diagnóstico de afasia primaria progresiva (APP) variante no fluente o agramatical, con síntomas comportamentales y motores asociados. Conclusión: Las APP son un grupo de trastornos neurocognitivos cuya característica primordial es el compromiso en el lenguaje, cada variante de APP tiene unas características clínicas y criterios diagnósticos específicos que se deben conocer para lograr sospechar el diagnóstico y hacer un abordaje apropiado en el paciente.


Introduction: In the group of neurodegenerative diseases, there is a group of pathologies that are characterized by a prominent compromise of language, normally called primary progressive aphasias, these are subdivided into 3 types: logopenic variant, semantic variant and non-fluent or agrammatic variant. Case presentation: Patient with a clinical picture that begins at age 65, with decreased social interaction, a couple of months later his wife notices that his language becomes not fluent, speaks in short words or phrases, cannot say complete sentences, in addition to changes in the intonation of words and alterations in written language, the patient states that his main limitation at the moment is not being able to express what he wants to say and for this reason they consult. Discussion: In the case of this patient, a change in his personality is initially described that does not compromise his functionality, however soon after a language involvement is presented as the main symptom and the one that generates a compromise in his quality of life, with neuropsychological tests and findings on neuroimaging that supports the diagnosis of primary progressive aphasia (PPA) non-fluent or agrammatical variant, with associated behavioral and motor symptoms. Conclusion: APPs are a group of neurocognitive disorders whose primary characteristic is language impairment. Each APP variant has specific clinical characteristics and diagnostic criteria that must be known in order to suspect the diagnosis and make an appropriate approach to the patient.

ABSTRACT

BACKGROUND AND PURPOSE: To analyze 18F-THK5351 positron emission tomography (PET) scans of patients with clinically diagnosed nonfluent/agrammatic variant primary progressive aphasia (navPPA). METHODS: Thirty-one participants, including those with Alzheimer's disease (AD, n=13), navPPA (n=3), and those with normal control (NC, n=15) who completed 3 Tesla magnetic resonance imaging, 18F-THK5351 PET scans, and detailed neuropsychological tests, were included. Voxel-based and region of interest (ROI)-based analyses were performed to evaluate retention of 18F-THK5351 in navPPA patients. RESULTS: In ROI-based analysis, patients with navPPA had higher levels of THK retention in the Broca's area, bilateral inferior frontal lobes, bilateral precentral gyri, and bilateral basal ganglia. Patients with navPPA showed higher levels of THK retention in bilateral frontal lobes (mainly left side) compared than NC in voxel-wise analysis. CONCLUSIONS: In our study, THK retention in navPPA patients was mainly distributed at the frontal region which was well correlated with functional-radiological distribution of navPPA. Our results suggest that tau PET imaging could be a supportive tool for diagnosis of navPPA in combination with a clinical history.

ABSTRACT

Frontotemporal dementia (FTD) is a degenerative disease characterized by the selective frontal and temporal lobe atrophy, and progressive deficits in behavior, executive function, or language. The prevalence and incidence of FTD are 15-22/100000 and 2.7-4.1/100000, respectively, in midlife. Hereditary is an important risk factor for FTD. Although there is some controversy regarding the further syndromatic subdivision of the different types of FTD, FTD is clinically classified into behavioral variant of frontotemporal dementia, semantic dementia and progressive nonfluent aphasia. FTD can be misdiagnosed as many psychiatric disorders because of similarity of the prominent behavioral features. Advances in clinical, imaging, and molecular characterization have increased the accuracy of FTD diagnosis, thus developing for the accurate differentiation of these syndromes from psychiatric disorders. We also discuss about therapeutic strategies for symptom management of FTD. Medications such as serotonin reuptake inhibitors, antipsychotics, and other novel treatments have been used in FTD with various rates of success. Further advanced research should be directed at understanding and developing new diagnostic and therapeutic modalities to improve the FTD patients' prognosis and quality of life.

ABSTRACT

The aim of this paper is to analyze the effects of intensive speech therapy intervention in a case of progressive non-fluent aphasia (PNFA). This is a dementia syndrome characterized by a progressive deficit in expressive language fluency and syntactic analysis, and by agrammatism and phonemic paraphasias. Although in the early stages there are no alterations in memory, comprehension, or visual processing, personality changes can slightly occur. To analyze the effects of speech therapy in this syndrome, a single case design with pre- and post-test was used. The participant was a male patient of 84 years with PNFA, who for twelve months received weekly speech therapy to stimulate the phonological, lexical and syntactic processing. He underwent neuropsychological assessment in three stages: six months before the onset of therapy, six months after therapy started and after completing 12 months of intervention. Assessment involved linguistic processing, general cognition, neuropsychiatric symptoms, quality of life (QOL) and activities of daily living (ADL). As a result of therapy, the patient showed a slight improvement in language prosody, fluency, and content of spontaneous speech, and a significant improvement in repetition, reading aloud, and oral-phonatory praxis. Other aspects of cognitive functioning (orientation, verbal naming, praxis, and memory) remained stable; ADLs and QOL improved. It is concluded that prolonged speech therapy can improve language processing and have a positive impact on other cognitive and socio-emotional processes in PNFA. This 12-month therapeutic stimulation not only slowed cognitive decline, but allowed to see maintenance of achievements and improvement of symptoms, which can be regarded as a success in PNFA treatment, considering the rapid progression of the disease.


El objetivo de este artículo es analizar los efectos de una intervención intensiva de terapia del lenguaje en un caso de afasia progresiva no fluente (APNF). Este es un síndrome demencial caracterizado por un déficit progresivo en la fluidez del lenguaje expresivo y el análisis sintáctico, y por agramatismo y parafasias fonémicas. Aunque en las primeras etapas no presenta alteraciones en la memoria, la comprensión o el procesamiento visual, sí pueden presentarse ligeros cambios en la personalidad. Para analizar los efectos de la terapia del lenguaje en este síndrome, se utilizó un diseño de caso único con pre y post prueba. El participante fue un paciente masculino de 84 años con APNF, quien durante doce meses recibió una terapia de lenguaje semanal para estimular el procesamiento fonológico, léxico y sintáctico. Se le realizó una evaluación neuropsicológica en tres etapas: seis meses antes del inicio de la terapia, después de seis meses de intervención, y al completar 12 meses de esta. Específicamente se evaluó el procesamiento lingüístico, la cognición general, los síntomas neuropsiquiátricos, la calidad de vida (CdV) y las actividades de la vida diaria (AVD). Como resultado de la terapia, el paciente mostró ligeras mejorías en la prosodia, la fluidez y el contenido del lenguaje espontáneo, y una mejoría significativa en la repetición, la lectura en voz alta y las praxias orofonatorias. Otros aspectos cognitivos (orientación, denominación verbal, praxias y memoria) se mantuvieron estables; las AVD y la CDV mejoraron. Se concluye que la terapia del lenguaje prolongada puede mejorar el procesamiento lingüístico y también tener un impacto positivo en otros procesos cognitivos y socio-emocionales en la APNF. La intervención no solo disminuyó la velocidad del deterioro cognitivo, sino que permitió ver el mantenimiento de los logros y la mejoría de los síntomas, lo cual es un éxito en el tratamiento de la APNF, debido a su rápida progresión.


O objetivo deste artigo é analisar os efeitos de uma intervenção intensiva de terapia da linguagem em um caso de afasia progressiva não fluente (APNF). Esta é uma síndrome demencial caracterizada por um déficit progressivo na fluência da linguagem expressiva e da análise sintática, e por agramatismo e parafasias fonêmicas. Ainda que nas primeiras etapas não presenta alterações na memória, na compreensão ou no processamento visual, podem aparecer pequenas mudanças na personalidade. Para analisar os efeitos da terapia da linguagem nesta síndrome, utilizou-se um desenho de caso único com testes antes e depois. O participante foi um paciente masculino de 84 anos com APNF, que durante doze meses recebeu uma terapia de linguagem semanal para estimular o processamento fonológico, léxico e sintático. Realizou-se uma avaliação neuropsicológica em três etapas: seis meses antes do início da terapia, depois de seis meses de intervenção, e ao completar 12 meses desta. Avaliou-se especificamente o processamento linguístico, a cognição geral, os sintomas neuropsiquiátricos, a qualidade de vida (QdV) e as atividades da vida diária (AVD). Como resultado da terapia, o paciente mostrou pequenas melhorias na prosódia, na fluência e no conteúdo da linguagem espontânea, e uma melhoria significativa na repetição, na leitura em voz alta e nas praxias orofonatórias. Outros aspectos cognitivos (orientação, denominação verbal, praxias e memória) mantiveram-se estáveis; as AVD e a QdV melhoraram. Conclui-se que a terapia da linguagem prolongada pode melhorar o processamento linguístico e também ter um impacto positivo em outros processos cognitivos e sócio emocionais na APNF. A intervenção diminuiu não somente a velocidade da deterioração cognitiva, senão que permitiu ver a manutenção dos êxitos e a melhoria dos sintomas, o que representa um sucesso no tratamento da APNF, devido a sua rápida progressão.

ABSTRACT

Introdução: A demência frontotemporal (DFT) inclui a variante comportamental da demência frontotemporal (vcDFT), a variante semântica da afasia progressiva primária (vsAPP), e a variante não fluente da APP (vnfAPP). Os genes em que são encontradas mutações causadoras de DFT mais frequentemente são: GRN (que codifica a progranulina), MAPT (que codifica a proteína tau) e C9orf72. Métodos: Foram incluídos probandos diagnosticados com vcDFT, vsAPP ou vnfAPP, com base com os critérios diagnósticos mais recentes, e um grupo de indivíduos cognitivamente normais. Os éxons 2-12 de GRN e os éxons 1, 9-13 de MAPT foram sequenciados pelo método de Sanger, e foi realizada dosagem de progranulina no plasma. Resultados: foram incluídos 62 probandos, sendo 44 com vcDFT, 9 com vsAPP, e 9 com vnfAPP. Antecedente familiar de demência foi positivo em 45,1% dos probandos, e de DFT, em 24,1%. Os 60 indivíduos do grupo controle tinham idade média de 60,8±8,5 anos. Foram identificadas seis mutações nulas em GRN (p.Q130X, p.V200Gfs*18, p.Q257Pfs*26, p.Q300X, p.S301Cfs*60 e p.D317Afs*11) e uma mutação patogênica em MAPT (p.N279K). A dosagem média de progranulina plasmática nos pacientes com mutações de GRN foi de 29,8±11,9ng/ml Conclusões: A frequência de mutações patogênicas em GRN nesta casuística foi de 9,6%, e a de mutações em MAPT foi de 1,6%. Entre casos familiais de DFT, a frequência de mutações em GRN foi de 33,3%, e em MAPT foi de 6,7%. Duas das mutações encontradas em GRN (p.Q130X e p.D317Afs*11) ainda não foram descritas em casos de DFT. O valor de corte de 70ng/ml identificou as mutações nulas de GRN com sensibilidade e especificidade de 100%.


Introduction: Frontotemporal dementia (FTD) encompasses behavioral variant of frontotemporal dementia (bvFTD), semantic variant of primary progressive aphasia (svPPA), and nonfluent variant PPA (nfvPPA). The genes in which FTD-causing mutations are most frequently found are: GRN (which encodes progranulin), MAPT (which encodes tau protein) and C9orf72. Methods: We included probands diagnosed with bvFTD, svPPA or nfvPPA, based on the most recent diagnostic criteria, and a group of cognitively normal individuals. GRN exons 2-12 and MAPT exons 1, 9-13 were sequenced by the Sanger method, and plasma progranulin levels were measured. Results: we included 62 probands (44 with bvFTD, 9 with svPPA, and 9 with nfvPPA). Family history of dementia was positive in 45.1% of probands, and of DFT, in 24.1%. The control group of 60 individuals had a mean age of 60.8±8.5 years. Six null GRN mutations were identified in (p.Q130X, p.V200Gfs*18, p.Q257Pfs*26, p.Q300X, p.S301Cfs*60 e p.D317Afs*11) and one MAPT pathogenic mutation (p.N279K). The mean plasma progranulin level in patients with GRN mutations was 29.8±11,9ng/ml. Conclusions: The frequency of pathogenic mutations in GRN was 9.6%, and of MAPT mutations was 1.6%. Among cases of familial FTD, the frequency of GRN mutations was 33.3%, and of MAPT mutations was 6.7%. Two of the mutations found in GRN (p.Q130X and p.D317Afs*11) are novel. The cutoff value of 70ng/ml identified null GRN mutations with sensitivity and specificity of 100%.

ABSTRACT

Purpose To investigate and to compare quality of life (QOL) in fluent and non-fluent aphasics. Methods This is a prospective, quantitative, and transversal study. We included 11 stroke patients with aphasia (five non-fluent aphasics augmentative and alternative communication users and six fluent aphasics). Data was gathered from the Stroke Specific Quality of Life Scale (SS-QOL), a structure interview, and The Modified Rankin Scale. Results The non-fluent aphasics presented poorer Rankin and quality of life than the fluent aphasics. The major difference occurred in the fields of language and upper extremity function. The three most affected domains in non-fluent aphasics were language, social roles, and thinking, whereas in the fluent aphasics were personality, social roles, and thinking. All the subjects referred a worse quality of life after stroke. The domains of language and self-care were identified as the most affected after stroke. Conclusion This study demonstrated that, in general, non-fluent aphasics have lower quality of life than fluent aphasics. However, this difference is not homogeneous among the several quality of life domains. Additionally, this research evidences a relationship between aphasia severity and individual functionality, implying impairment in quality of life, especially for non-fluent aphasics. .


Objetivo Investigar e comparar a qualidade de vida de afásicos fluentes e não fluentes. Métodos Trata-se de pesquisa prospectiva, quantitativa, transversal, cuja amostra se constituiu de 11 sujeitos afásicos (5 não fluentes, usuários de comunicação suplementar e/ou alternativa e 6 fluentes, não usuários de comunicação suplementar e/ou alternativa. A coleta de dados foi realizada por meio da aplicação de um questionário específico de qualidade de vida, entrevista estruturada e aplicação da escala de Rankin modificada. Resultados Na comparação dos grupos estudados, os afásicos não fluentes apresentaram escores de Rankin e de qualidade de vida menores do que os fluentes e as maiores diferenças referiram-se aos domínios de linguagem e função do membro superior. Os domínios mais prejudicados pelo acidente vascular cerebral foram linguagem, relações sociais e modo de pensar, para os afásicos não fluentes, e comportamento, relações sociais e modo de pensar, para os fluentes. Todos os sujeitos relataram que sua qualidade de vida piorou após o acidente vascular cerebral, sendo que linguagem e cuidados pessoais foram apontados como os aspectos que mais mudaram, após o episódio lesional. Conclusão Os achados mostram relação entre gravidade da afasia e funcionalidade do indivíduo, indicando que, no geral, os afásicos não fluentes apresentam qualidade de vida pior do que os fluentes. As diferenças não são homogêneas nos diversos domínios de qualidade de vida. .

ABSTRACT

OBJETIVO: Caracterizar os fatores gênero, idade, tempo de duração e tipologia das disfluências, fatores estressantes físicos e emocionais em crianças com alto risco para a gagueira e com recorrência familial do distúrbio. MÉTODOS: Participaram 65 crianças com alto risco para a gagueira desenvolvimental familial, de ambos os gêneros, na faixa etária de três a 11anos. A coleta de dados foi realizada por meio do Protocolo de Risco para a Gagueira do Desenvolvimento (PRGD). RESULTADOS: A razão masculino/feminino de crianças disfluentes encontrada foi de 2,8:1, com predominância do grupo na faixa etária de três anos. Os resultados revelaram diferença significativa quanto ao tempo de duração: mais crianças apresentaram um período maior de 12 meses de duração das disfluências em relação às crianças que apresentaram de seis a 12 meses de duração. A maioria apresentou algum fator estressante emocional e não apresentou fator estressante físico. CONCLUSÃO: Os resultados sugerem que crianças com recorrência familial da gagueira no gênero masculino, na faixa etária de três anos, com presença de disfluências gagas por mais de 12 meses e com ocorrência de fatores estressantes emocionais são as que apresentam maior risco para o desenvolvimento da gagueira persistente.


PURPOSE: To characterize the factors gender, age, duration and typology of the disfluencies; physical and emotional stresses in children with high risk for stuttering and with familial recurrence of the disorder. METHODS: Sixty-five children with high risk for developmental familial stuttering of both genders, with ages between 3 and 11 years and 11 months. The data were gathered through the Protocol of Risk for the Developmental Stuttering. RESULTS: In our findings the ratio male:female was 2.8:1, and the majority of the children were aged 3 years old. Significantly more children presented more than 12 months' duration of the disfluencies when compared to children that presented 6 to 12 months' duration. The majority showed some emotional stress and didn't show any physical stress. CONCLUSION: The results of this study suggest that children with familial recurrence of stuttering, male, with 3 years old, with stuttering-like disfluencies (SLD) lasting for more than 12 months and with the occurrence of emotional stresses are the children that present the higher risk for the development of the persistent stuttering.

ABSTRACT

Frontotemporal dementia (FTD), formerly called Pick's disease, is a progressive dementia that is associated with focal atrophy of the frontal and/or temporal lobes. FTD has three major clinical subtypes ; 1) a frontal variant of frontotemporal dementia (fvFTD), 2) semantic dementia (SD), and 3) progressive nonfluent aphasia (PNFA). These different variants differ in their clinical symptoms, cognitive deficits, and affected brain regions. The insidious onset of personality changes and behavioral abnormalities is the most prominent feature of fvFTD. Poor insight, loss of personal and social awareness, and blunting of affect are common behavioral changes in fvFTD. The most common presenting complaint in SD involves language, and is often described as a loss of memory for words or a loss of word meaning. Patients with PNFA present with changes in fluency, pronunciation, or word finding difficulty. An accumulating body of evidence suggests that FTD overlaps with three other neurodegenerative diseases: motor neuron disease (MND), corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP). Treatment for FTD consists of behavioral and pharmacological approaches. Medications such as selective serotonin reuptake inhibitors, antipsychotics have used in FTD. Cholinesterase inhibitors do not consistently improve cognitive and behavioral symptoms of FTD. Further research should be directed at developing new therapeutic methods to improve the patients' symptoms.

ABSTRACT

A woman developed a slowly progressive speech disturbance at age 51. Three years latter she showed difficulty in calculation, reading and writing. At age 57, she complained of right shoulder pain. At age 58, neurological examination revealed rigidity, bradykinesia and ideomotor apraxia in the right upper extremity. This case demonstrats a clinical overlap between progressive nonfluent aphasia and corticobasal degeneration.

ABSTRACT

Frontotemporal lobar degeneration (FTLD) is a progressive dementia with prominent neuropsychiatric features, aphasia or both. FTLD predominantly affects the frontal and anterior part of temporal cortex. FTLD is classified into frontotemporal dementia (FTD), progressive nonfluent aphasia (PA), and semantic dementia (SD). FTLD is estimated to account for 20% of cases of degenerative dementia with presenile onset. This disease typically has onset in the mid- or early fifties. FTD is characterized by behavioral change and executive dysfunction, PA features a progressive nonfluent aphasia. SD is characterized by a progressive semantic aphasia and associative agnosia. Structural imaging shows atrophy of the frontal lobe and the anterior portion of the temporal lobe, bilaterally symmetric or asymmetric. Pathologically, FTLD can be classified into tau-positive pathology, tau-negative, ubiquitin positive pathology, dementia lacking distinctive histology. At present, there are no specific pharmacological therapies approved for use in any of the FTLD syndrome.

ABSTRACT

It is not uncommon for idiopathic parkinson's disease (IPD) to occur concurrently with other degenerative dementing disorders such as Alzheimer's disease. However, there has been no report about the comorbidity of IPD and frontotemporal lobar degeneration. We report a 70-year-old man diagnosed with IPD accompanied by progressive non-fluent aphasia (PA). Brain MRI showed left frontal opercular atrophy, and an 18F-FDG PET scan revealed predominant left frontotemporal hypometabolism. It remains unknown whether or not the co-occurrence of IPD and PA was coincidental.
