Test for clinical reasoning evaluation in Speech-Language Pathology: content validity. / Teste para avaliação do raciocínio clínico em Fonoaudiologia: validade de conteúdo.

PURPOSE: To validate the content of the Speech-Language Pathology Concordance Test called FonoTCS. METHODS: This is a content validation study of the instrument. Five speech-language pathologists, all with doctoral degrees and teaching experience, averaging 24.8 years of professional practice, participated in the development of FonoTCS and reached a consensus during the process. Thirty questions and 120 items were created, covering seven areas of speech-language pathology expertise across three domains. For content validation, FonoTCS was electronically sent to 15 evaluators to respond to a questionnaire with five questions, rated on a five-point scale, regarding the criteria of clarity, ethics, and relevance of the questions. The Corrected Content Validity Coefficient was calculated for all statements to analyze the responses. Questions with agreement percentages equal to or less than 80% were revised. RESULTS: Thirteen evaluators, all female, with an average age of 39.07 years, including eight with master's degrees and five with doctoral degrees, and an average clinical practice experience of 15.38 years, participated in the analysis. The average Corrected Content Validity Coefficient values for the clarity criterion were 0.93 and 0.95, for the relevance criterion 0.98 and 0.92, and for the ethics criterion 0.99. Two questions received scores of 0.78 and 0.80, both related to the audiology area in the assessment/diagnosis domain, specifically question 2 regarding the relevance criterion. These questions were reviewed and restructured by the judges. CONCLUSION: FonoTCS is a valid instrument from a content perspective.

Effects of Hearing Aid Use on Individuals Diagnosed with Hearing Loss and Dementia: A Systematic Review.

Background: The assumption that hearing rehabilitation could improve quality of life and reduce dementia risk in people with hearing loss is a subject that needs further studies, especially clinical trials. It is necessary to determine the effects of hearing aid use, as part of hearing rehabilitation, among people diagnosed with dementia. Objective: To systematically review the literature to evaluate the effects of hearing aid use on cognition and quality of life of people with dementia. Methods: Protocol for this systematic review was registered (CRD42023387187). The Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Scopus, CINAHL, and Web of Science databases, as well as grey literature, including Google Scholar and ResearchGate, were systematically searched for clinical trials using MeSH terms. The PICOS principle was used to develop the inclusion criteria: population (P): adults and older adults, individuals diagnosed with dementia and hearing loss; intervention (I): rehabilitation with hearing aids; control (C): not using a hearing aid; outcome (O): cognitive and/or quality of life assessment using validated tests; study design (S): clinical trial. Results: The initial search yielded 576 studies, five of which met the inclusion criteria for qualitative analyses. Two of the included studies were randomized clinical trials, and three were crossover clinical trials, demonstrating the lack of studies on the subject. Four studies included participants with Alzheimer's disease. Quality of life was found to improve with the use of hearing aids, and hearing rehabilitation was not shown to affect cognitive outcomes. Conclusions: Hearing aid use appears to have a positive impact on quality of life.

Association of Alcohol Consumption with Cognition and Functionality in Older Adults Aged 75+ Years: The Pietà Study.

The relationship between alcohol consumption and cognition is still controversial. This is a cross-sectional population-based study conducted in Caeté (MG), Brazil, where 602 individuals aged 75+ years, 63.6% female, and with a mean education of 2.68 years, were submitted to thorough clinical assessments and categorized according to the number of alcoholic beverages consumed weekly. The prevalence rates of previous and current alcohol consumption were 34.6% and 12.3%, respectively. No association emerged between cognitive diagnoses and current/previous alcohol consumption categories. Considering current alcohol intake as a dichotomous variable, the absence of alcohol consumption was associated with dementia (OR = 2.34; 95%CI: 1.39-3.90) and worse functionality (p = 0.001). Previous consumption of cachaça (sugar cane liquor) increased the risk of dementia by 2.52 (95%CI: 1.25-5.04). The association between the consumption of cachaça and dementia diagnosis has not been described before.

High performance older adults in a population-based sample with low education: Pietà study.

BACKGROUND: Healthy brain aging can be defined as aging without neurological or psychiatric disorders, sustaining functional independence. In addition to the absence of disease and preserved functionality, there are individuals who stand out for their superior performance to that considered normal for their age in cognitive tests. These individuals are called "high-performance older adults" (HPOA). OBJECTIVES: To investigate the presence of HPOA in an oldest-old population with low education, and if present, to investigate associations with sociodemographic, clinical, and lifestyle variables. METHODS: We evaluated 132 cognitively healthy individuals from the Pietà Study, a population-based investigation with 639 participants. We used the delayed recall from the Rey Auditory-Verbal Learning Test to verify the existence of HPOA and to classify participants based on their performance. Sociodemographic, clinical, and lifestyle variables associated with HPOA were investigated. RESULTS: We identified 18 individuals fulfilling HPOA criteria (age: 77.4 ± 2.6 years old; 14 women; education: 4.6 ± 3.4 years). The other participants, 114 total (age: 79.8 ± 4.5 years old; 69 women; education: 3.0 ± 2.7 years) were classified as "standard performance older adults" (SPOA). In multivariate analysis, younger age (odds ratio [OR] = 0.672; 95% confidence interval [CI]: 0.462-0.979; p = 0.037) and lower scores on the Geriatric Depression Scale (OR = 0.831; 95%CI: 0.688-0.989; p = 0.038) were associated with HPOA. CONCLUSIONS: The present study identifies for the first time HPOA with low educational level, thereby reinforcing the existence of biological substrates related to this condition. Furthermore, the data suggest an association between younger age and less depressive symptoms with HPOA.

ANTECEDENTES: Envelhecimento cerebral saudável pode ser definido como envelhecimento sem transtornos neurológicos ou psiquiátricos e com independência funcional. Além da ausência de doença e funcionalidade preservada, existem indivíduos que se destacam pelo desempenho superior ao normal em testes cognitivos. Estes indivíduos são chamados de "high performance older adults" (HPOA, na sigla em inglês). OBJETIVOS: Investigar a presença de HPOA em uma população de idosos com baixa escolaridade e, se presente, investigar associações com variáveis sociodemográficas, clínicas e de estilo de vida. MéTODOS: Avaliamos 132 indivíduos cognitivamente saudáveis do Estudo Pietà (n = 639). Foi utilizado o Teste de Aprendizagem Auditivo-Verbal de Rey para verificar a existência de HPOA e classificar os participantes em dois grupos com base em seu desempenho. Variáveis sociodemográficas, clínicas e de estilo de vida associadas a HPOA foram investigadas. RESULTADOS: Identificamos 18 indivíduos que preencheram critérios para HPOA (idade: 77,4 ± 2,6 anos; 14 mulheres; escolaridade: 4,6 ± 3,4 anos). Os demais, 114 no total (idade: 79,8 ± 4,5 anos; 69 mulheres; escolaridade: 3,0 ± 2,7 anos), foram classificados como "standard performance older adults" (SPOA, na sigla em inglês). Na análise multivariada, menor idade (odds ratio [OR] = 0,672; intervalo de confiança [IC] 95%: 0,462­0,979; p = 0,037) e menor pontuação na Escala de Depressão Geriátrica (OR = 0,831; IC95%: 0,688­0,989; p = 0,038) foram associados ao grupo HPOA. CONCLUSõES: O presente estudo identifica pela primeira vez HPOA entre indivíduos de baixa escolaridade, reforçando a existência de substratos biológicos relacionados a esta condição. Além disso, os dados sugerem uma associação entre idade mais jovem e menos sintomas depressivos com HPOA.

Investigation of the Association Between History of Learning Disabilities and Primary Progressive Aphasia in Brazilian Portuguese Speakers.

Primary Progressive Aphasia (PPA) is a neurological syndrome characterized by impaired language due to neurodegeneration. It is subdivided into three variants: semantic, agrammatic or nonfluent, and logopenic. Pieces of evidence have suggested that learning disabilities in childhood, such as dyslexia, might be susceptibility factors in the occurrence of PPA in adulthood. The objective of this study was to verify the existence of the relationship between PPA and the history of learning disabilities of patients and their children, compared to a control group of individuals with Alzheimer's disease (AD). A questionnaire was applied to investigate the presence of indicators of learning disabilities and difficulties in individuals with PPA and AD and their children. Twenty subjects with PPA and 16 with AD participated in the study. Our findings are presented and discussed in light of the current scientific evidence and the social, educational, and economic Brazilian scenario. Despite the challenges of doing research with individuals with PPA in Brazil, we present the first evidence about the investigation of association between the history of learning disabilities and difficulties and PPA in native Brazilian Portuguese speakers.

Sentence Comprehension in Primary Progressive Aphasia: A Study of the Application of the Brazilian Version of the Test for the Reception of Grammar (TROG2-Br).

Sentence-comprehension deficits have been described in patients with primary progressive aphasia (PPA). However, most instruments to address this domain in more detail and in a clinical context have not been adapted and translated into several languages, posing limitations to clinical practice and cross-language research. Objectives: The study aimed to (1) test the applicability of the Brazilian version of the Test for Reception of Grammar (TROG2-Br) to detect morphosyntactic deficits in patients with PPA; (2) investigate the association between performance in the test and sociodemographic and clinical variables (age, years of formal education, and disease duration); (3) characterize the performance of individuals presenting with the three more common variants of PPA (non-fluent, semantic, and logopenic) and mixed PPA (PPA-Mx) and analyze whether TROG-2 may assist in the distinction of these clinical profiles. Methods: A total of 74 cognitively healthy participants and 34 individuals diagnosed with PPA were assessed with TROG2-Br. Overall scores (correct items, passed blocks), types, and categories of errors were analyzed. Results: In controls, block scores were significantly correlated with years of formal education (Spearman's r = 0.33, p = 004) but not with age. In PPA, age, education, and disease duration were not significantly associated with performance in the test. Controls presented a significantly higher performance on TROG2-Br compared to PPA individuals and their errors pattern pointed to mild general cognitive processing difficulties (attention, working memory). PPA error types pointed to processing and morphosyntactic deficits in nonfluent or agrammatic PPA, (PPA-NF/A), logopenic PPA (PPA-L), and PPA-Mx. The semantic PPA (PPA-S) subgroup was qualitatively more similar to controls (processing difficulties and lower percentage of morphosyntactic errors). TROG2-Br presented good internal consistency and concurrent validity. Discussion: Our results corroborate findings with TROG-2 in other populations. The performance of typical older adults with heterogeneous levels of education is discussed along with recommendations for clinical use of the test and future directions of research.

Diagnosis of frontotemporal dementia: recommendations of the Scientific Department of Cognitive Neurology and Aging of the Brazilian Academy of Neurology.

"Frontotemporal dementia" (FTD) is a clinical syndrome characterized by the focal involvement of the frontal and/or temporal lobes. FTD has three clinical phenotypes: the behavioral variant and two linguistic subtypes, namely, non-fluent/agrammatic primary progressive aphasia (PPA-NF/A) and semantic PPA (PPA-S). FTD is the second most common cause of dementia in individuals under the age of 65 years. This article presents recommendations for the diagnosis of FTD in the Brazilian scenario, considering the three levels of complexity of the health system: primary health care, secondary and tertiary levels. Diagnostic guidelines are proposed, including cognitive testing, behavioral and language assessments, laboratory tests, and neuroimaging.

A "demência frontotemporal" (DFT) é uma síndrome clínica, cujo denominador comum é o acometimento focal dos lobos frontais e/ou temporais. A DFT tem três fenótipos clínicos distintos: a variante comportamental e dois subtipos linguísticos, a saber, a afasia progressiva primária não-fluente/agramática (APP-NF/A) e a afasia progressiva primária semântica (APP-S). A DFT é a segunda causa mais comum de demência em indivíduos com idade inferior a 65 anos, após a doença de Alzheimer. O presente artigo apresenta recomendações para diagnóstico da DFT no cenário brasileiro, considerando os três níveis de complexidade do sistema de saúde: atenção primária à saúde e níveis secundários. São propostos protocolos de investigação diagnóstica abrangendo testagem cognitiva, avaliação comportamental, avaliação fonoaudiológica, exames laboratoriais e de neuroimagem.

Cognitive Intervention Strategies Directed to Speech and Language Deficits in Primary Progressive Aphasia: Practice-Based Evidence from 18 Cases.

BACKGROUND: Practice-based evidence can inform and support clinical decision making. Case-report series about the implementation of programs in real-world clinical settings may contribute to verifying the effectiveness of interventions for treating PPA in specific contexts, as well as illustrating challenges that need to be overcome. OBJECTIVE: To describe and provide practice-based evidence on the effectiveness of four cognitive rehabilitation programs designed for individuals with PPA and directed to speech and language impairments, which were implemented in a specialized outpatient clinic. METHODS: Multiple single-case study. Eighteen individuals with different subtypes of PPA were each assigned to one out of four training programs based on comprehensive speech and language assessments. The treatments targeted naming deficits, sentence production, speech apraxia, and phonological deficits. Pre- and post-treatment assessments were undertaken to compare trained and untrained items. Gains were generalized to a different task in the first two types of intervention (naming and sentence production). A follow-up assessment was conducted 1-8 months after treatment among 7 participants. RESULTS: All individuals presented better performance in the trained items at the post-test for each rehabilitation program accomplished, demonstrating that learning of the trained strategies was achieved during the active phase of treatment. For 13 individuals, statistical significance was reached; while for five, the results were maintained. Results about untrained items, generalization to other tasks, and follow-up assessments are presented. CONCLUSIONS: The positive results found in our sample bring some practice-based evidence for the benefits of speech and language treatment strategies for clinical management of individuals with PPA.

First Symptoms of Primary Progressive Aphasia and Alzheimer's Disease in Brazilian Individuals.

Background: Primary Progressive Aphasia (PPA) is characterized by progressive language impairment due to focal degeneration of brain areas related to linguistic processing. The detection and differential diagnosis of PPA can be difficult with clinical features that may overlap with features of other neurological conditions, such as Alzheimer's disease (AD). The scientific production on PPA in Latin American patients is still scarce. This study investigated the first symptoms in a Brazilian sample of patients with PPA in comparison with AD patients. Method: We compared the first symptoms reported by caregivers of people with PPA (n = 20; semantic variant n = 8, non-fluent variant n = 7, logopenic variant n = 3, and unclassified cases n = 2) and AD (n = 16). Data were collected through the application of a structured questionnaire that was presented in an interview format to the caregiver who knew the patient best. Results: Anomia, paraphasias and motor speech difficulties were the first symptoms capable of differentiating patients with PPA from those with AD, while memory was exclusive of AD. Among the PPA variants, anomia was the initial symptom associated with the semantic variant, while motor speech difficulties were associated with the non-fluent variant. The results are discussed considering the unique cultural and sociodemographic characteristics of this studied population. Conclusion: This study demonstrated that some of the initial symptoms of PPA patients may be unique to clinical variants of PPA and of AD, and their investigation may be useful for the early and differential diagnosis of this population.

Ischemic cerebrovascular burden evaluated by magnetic resonance imaging in an elderly Brazilian community: The Pietà study.

In developing countries, cardiovascular risk factors are poorly controlled, leading to high prevalence of cerebrovascular diseases. The aim of the study was to evaluate the burden of white matter lesions in magnetic resonance through the Fazekas scale in a population aged 75 + years living in the community, and to investigate possible associations between vascular lesions, cardiovascular risk factors and cognitive status. Subjects were selected from a community-based study on brain aging conducted in Caeté (Minas Gerais state), Brazil. Overall, 177 participants (112 cognitively healthy, 36 with cognitive impairment-no dementia and 29 with dementia), being 108 women, aged 79.3 ± 3.8 years, with 3.1 ± 2.9 years of educational level, underwent a 3 Tesla magnetic resonance scanner with fluid attenuated image recovery acquisition. Severity of white matter lesions was assessed through the Fazekas scale. Severe white matter lesions were present in 31.1% of the whole sample and in 25.0% of the cognitively healthy individuals. A significant association was found between severe white matter lesions and cognitive impairment (OR = 2.20, 95% CI 1.17-6.53; p = 0.021), as well as with hypertension (OR = 1.92, 95% CI 1.03-7.39; p = 0.043). In conclusion, a high prevalence of severe white matter lesions was observed in this elderly Brazilian population sample, and white matter lesions were associated with hypertension and cognitive status. Importantly, the prevalence of white matter lesions was also high in cognitively healthy subjects.

Brief intervention for agrammatism in Primary Progressive Nonfluent Aphasia: A case report.

The non-fluent and agrammatic variant of Primary Progressive Aphasia (NFPPA) is characterized by reduced verbal production with deficits in building grammatically correct sentences, involving dysfunctions in syntactic and morphological levels of language. There are a growing number of studies about non-pharmacological alternatives focusing on the rehabilitation of functional aspects or specific cognitive impairments of each variant of PPA. This study reports a short-term treatment administered to a patient with NFPPA focusing on the production of sentences. The patient had significant reduction in verbal fluency, use of keywords, phrasal and grammatical simplifying as well as anomia. Using the method of errorless learning, six sessions were structured to stimulate the formation of sentences in the present and past with the cloze technique. The patient had improvement restricted to the strategy, with 100% accuracy on the trained phrases and generalization to untrained similar syntactic structure after training. These results persisted one month after the treatment.

A variante não fluente e agramática da Afasia Progressiva Primária (APPNF) caracteriza-se por redução da produção verbal com falhas para construir sentenças gramaticalmente corretas, envolvendo disfunções nos níveis sintático e morfológico da linguagem. É crescente o número de pesquisas sobre alternativas não farmacológicas enfocando a reabilitação de aspectos funcionais ou comprometimentos cognitivos específicos de cada variante das APP. Relatar um tratamento de curta-duração administrado a um paciente com APPNF enfocando a produção de sentenças. O paciente apresentava redução importante da fluência verbal, uso de palavras-chave, simplificação frasal e gramatical, além de anomia. Utilizando o método de aprendizado sem erros, foram estruturadas seis sessões para estimular a formação de frases no presente e no passado com a técnica de cloze. O paciente apresentou melhora restrita à estratégia, com 100% de acerto nas frases treinadas e generalização para as não-treinadas de estrutura sintática semelhante após o treinamento. Os resultados foram mantidos um mês após o tratamento.

Apathy is not associated with performance in brief executive tests in patients with mild cognitive impairment and mild Alzheimer's disease.

Neuropsychological correlates of apathy in Alzheimer's disease (AD) may shed some light on the neurobiology of this behavioral disorder. Whereas previous research has suggested an association between apathy and executive functions in AD, amnestic mild cognitive impairment (aMCI) cohorts point to an association with memory tests. We aimed to further investigate this issue in a sample of low educated, hitherto unexposed to cholinesterase inhibitors, aMCI (n=26) and mild AD (n=28) patients using brief executive tests, namely the Executive Interview (EXIT-25) and the Frontal Assessment Battery (FAB). Patients and controls (n=33) were included from a community-based survey of successful brain aging in Brazilian elderly (75+ years), The Pietà Study. The participants were submitted to a comprehensively neuropsychological assessment and apathy evaluation through the Apathy Scale (AS).We found a strong correlation in AD group between AS scores and functional performance measured by the Disability Assessment in Dementia (rho =-0.7 ; p<0,001). No association was found between any executive test performance and apathy symptoms. Apathy symptoms were also associated with the performance in memory tests and in the attention subscale of the Mattis Dementia Rating Scale. These findings reinforce the functional effect of apathy even in the mildest stages along the AD cognitive impairment spectrum, and challenges previous assumptions regarding the association between apathy and classical executive functions.

Features associated with cognitive impairment and dementia in a community-based sample of illiterate elderly aged 75+ years: the Pietà study.

A higher level of educational attainment constitutes a protective factor against cognitive decline in the elderly. Nevertheless, the elements underpinning this association are yet not fully understood. OBJECTIVE: The primary aim of this study was to compare cognitively impaired illiterate elderly subjects with cognitively preserved counterparts, according to demographics, comorbidities, lifetime habits and APOE genotype. METHODS: This is a cross-sectional analysis of the illiterate subset of participants (n=174) from the Pietà study, a community-based survey of successful brain aging conducted in Caeté (MG), Brazil. Subjects were categorized into three diagnostic groups: cognitively normal (CN), cognitive impairment no-dementia (CIND) and dementia. The groups were then compared according to selected variables. RESULTS: Subjects with dementia were older and had an increased prevalence of reported stroke or transient ischemic attack. The three groups did not differ in relation to demographics, prevalence of comorbidities, socioeconomic level, previous occupation profile and APOE-ε4 allele frequency. Qualitatively evaluated lifetime habits, such as alcohol consumption, smoking and physical activity engagement were also similar across groups. CONCLUSION: No associations were found between cognitive impairment/dementia and the variables evaluated in this community-based sample of illiterate elderly.

Um alcance educacional mais elevado constitui um fator protetivo contra o declínio cognitivo em idosos. Todavia, os elementos subjacentes a esta associação ainda são pouco compreendidos. OBJETIVO: O principal objetivo deste estudo foi comparar indivíduos analfabetos com comprometimento cognitivo com analfabetos cognitivamente normais, de acordo com aspectos demográficos, morbidades, hábitos de vida e genótipo APOE. MÉTODOS: Este é um estudo transversal da amostra de participantes analfabetos (n=174) do Estudo Pietà, um levantamento de base comunitária sobre envelhecimento cerebral bem sucedido, conduzido em Caeté (MG), Brasil. Os sujeitos foram categorizados em três grupos diagnósticos: cognitivamente normais, comprometimento cognitivo não demência e demência. Os grupos foram então comparados conforme variáveis selecionadas. RESULTADOS: Indivíduos com demência eram mais idosos e apresentaram uma maior prevalência de relato de acidente vascular encefálico ou ataque isquêmico transitório. Os três grupos não se mostraram diferentes em relação à demografia, prevalência de comorbidades, nível socioeconômico, perfil ocupacional prévio e frequência do alelo APOE-ε4. A avaliação qualitativa de hábitos de vida, como o consumo de bebida alcoólica, fumo e engajamento em atividade física também foi semelhante entre os grupos. CONCLUSÃO: Não encontramos associações entre comprometimento cognitivo/demência e as variáveis investigadas nesta amostra comunitária de idosos analfabetos.

Mattis dementia rating scale (DRS) normative data for the brazilian middle-age and elderly populations.

OBJECTIVE: To expand norms for the Mattis Dementia Rating Scale (DRS) for the Brazilian middle-age and elderly populations. METHODS: The DRS was administered to 502 individuals without cognitive deficits, 312 women and 190 men, aged 50 years or over and with educational level ranging from 0 to 13 years or more. The sample was composed of subjects who participated in other studies, from Caeté (Minas Gerais state), Ribeirão Preto (São Paulo state) and São Paulo (São Paulo state). Participants were divided into four schooling groups (illiterate, 1 to 4 years, 5 to 12 years and 13 years or more). The subjects were divided into four groups according to age (50 to 60, 61 to 70, 71 to 80, and 80 years or over). RESULTS: Normative data for DRS scores are expressed as percentile values. The group with lowest schooling and subjects older than 80 years had the worst scores. CONCLUSION: As expected, age and education were strongly correlated with DRS scores. Illiterates and older old individuals performed worse than the other groups. These data might help to improve the accuracy of the diagnosis of cognitive impairment and dementia in Brazilian middle-age and elderly populations.

OBJETIVO: Expandir normas para o Mattis Dementia Rating Scale (MDRS) na população brasileira de meia idade e idosa. MÉTODOS: A MDRS foi aplicada em 502 indivíduos, 312 mulheres e 190 homens, com idade de 50 anos ou mais e escolaridade de 0 a 13 anos ou mais anos. A amostra foi composta de sujeitos que participaram de outros estudos: Caeté (Minas Gerais), Ribeirão Preto (São Paulo) e São Paulo (São Paulo). Participantes foram divididos em quatro grupos de escolaridade (analfabetos, 1 a 4 anos, 5 a 12 anos e 13 anos ou mais). Os sujeitos foram divididos em quatro grupos de idade (50 a 60, 61 a 70, 71 a 80 e acima de 80 anos). RESULTADOS: Dados normativos dos escores da MDRS são apresentados em percentis. O grupo com menos escolaridade e sujeitos acima de 80 anos apresentaram escores mais baixos. CONCLUSÃO: Como esperado, idade e escolaridade foram fortemente correlacionados aos escores da MDRS. Analfabetos e indivíduos muito idosos apresentaram pior desempenho que os outros grupos. Os dados podem ajudar a melhorar a acurácia para o diagnóstico de prejuízo cognitivo e demência na população brasileira de meia-idade e idosos.

Nonpharmacological interventions for cognitive impairments following primary progressive aphasia: a systematic review of the literature.

This study provided a systematic review on nonpharmacological interventions applied to patients diagnosed with Primary Progressive Aphasia (PPA) and its variants: Semantic (SPPA), Nonfluent (NFPPA) and Logopenic (LPPA) to establish evidence-based recommendations for the clinical practice of cognitive rehabilitation for these patients. METHODS: A PubMed and LILACS literature search with no time restriction was conducted with the keywords PPA (and its variants) AND rehabilitation OR training OR intervention OR therapy OR treatment OR effectiveness. To develop its evidence-based recommendations, a research committee identified questions to be addressed and determined the level of evidence for each study according to published criteria (Cicerone et al., 2000). Overall evidence for treatments was summarized and recommendations were derived. RESULTS: Our search retrieved articles published from 1995 to 2013: 21 for SPPA, 8 for NFPPA, 3 for LPPA and 8 for PPA with no specification. Thirty-five studies were rated as Class III, consisting of studies with results obtained from one or more single-cases and that used appropriate single-subject methods with adequate quantification and analysis of results. The level of evidence of three functional interventions could not be established. One study was rated as Class II and consisted of a nonrandomized case-control investigation. CONCLUSION: Positive results were reported in all reviewed studies. However, in order to be recommended, some investigation regarding the intervention efficacy was required. Results of the present review allows for recommendation of some nonpharmacological interventions for cognitive deficits following PPA as Practice Options. Suggestions for further studies on PPA interventions and future research are discussed.

Este estudo ofereceu uma revisão sistemática de intervenções não-farmacológicas aplicadas a pacientes com Afasia Progressiva Primária (APP) e suas variantes: Semântica (APPS), Não-fluente (APPNF) e Logopênica (APPL) com o objetivo de estabelecer recomendações baseadas em evidências para a prática clínica de reabilitação cognitiva para estes pacientes. MÉTODOS: Conduziu-se busca por literatura, sem restrição de período, no PubMed e LILACS com as palavras-chave PPA (e variantes) AND rehabilitation OR training OR intervention OR therapy OR treatment OR effectiveness. Para desenvolver recomendações baseadas em evidências um comitê de pesquisadores identificou as questões relevantes para investigação e determinou o nível de evidência para cada estudo de acordo com critérios publicados (Cicerone et al., 2000). A evidência total para os tratamentos foi sumarizada e recomendações redigidas. RESULTADOS: Foram encontrados artigos publicados de 1995 a 2013: 21 para APPS, 8 para APPNF, 3 para APPL e 8 para APP sem especificações. Trinta e cinco estudos foram classificados como Classe III, consistindo de resultados obtidos com um ou mais indivíduos e utilizando metodologia apropriada para estudo de casos. O nível de evidência de três intervenções funcionais não pôde ser estabelecido. Um estudo foi classificado como Classe II e consistiu de pesquisa caso-controle não-randomizada. CONCLUSÃO: Resultados positivos foram reportados em todos os trabalhos analisados mas, para serem recomendados, os tratamentos requerem investigação em relação a sua eficácia. Resultados da presente revisão permitiram recomendação de algumas intervenções como Opções Práticas. Ademais, apresentamos sugestões para futuros estudos de intervenção em APP.

Brief intervention for agrammatism in Primary Progressive Nonfluent Aphasia: a case report / Intervenção breve para agramatismo em Afasia Progressiva Primária Não Fluente: relato de caso

The non-fluent and agrammatic variant of Primary Progressive Aphasia (NFPPA) is characterized by reduced verbal production with deficits in building grammatically correct sentences, involving dysfunctions in syntactic and morphological levels of language. There are a growing number of studies about non-pharmacological alternatives focusingon the rehabilitation of functional aspects or specific cognitive impairments of each variant of PPA. This study reports a shortterm treatment administered to a patient with NFPPA focusing on the production of sentences. The patient had significant reduction in verbal fluency, use of keywords, phrasal and grammatical simplifying as well as anomia. Using the method of errorless learning, six sessions were structured to stimulate the formation of sentences in the present and past with the cloze technique. The patient had improvement restricted to the strategy, with 100% accuracy on the trained phrases and generalization to untrained similar syntactic structure after training. These results persisted one month after the treatment.

A variante não fluente e agramática da Afasia Progressiva Primária (APPNF) caracteriza-se por redução da produção verbal com falhas para construir sentenças gramaticalmente corretas, envolvendo disfunções nos níveis sintático e morfológico da linguagem. É crescente o número de pesquisas sobre alternativas não farmacológicas enfocando areabilitação de aspectos funcionais ou comprometimentos cognitivos específicos de cada variante das APP. Relatar um tratamento de curta-duração administrado a um paciente com APPNF enfocando a produção de sentenças. O paciente apresentava redução importante da fluência verbal, uso de palavras-chave, simplificação frasal e gramatical, além deanomia. Utilizando o método de aprendizado sem erros, foram estruturadas seis sessões para estimular a formação de frases no presente e no passado com a técnica de cloze. O paciente apresentou melhora restrita à estratégia, com 100% de acerto nas frases treinadas e generalização para as não-treinadas de estrutura sintática semelhante após o treinamento.Os resultados foram mantidos um mês após o tratamento.
