Performance in microlinguistics at the lexical and syntactic levels was lower than expected in participants with AD.

Alzheimer's disease (AD) is characterized by impairments in memory and other cognitive functions such as language, which can be affected in all aspects including discourse. A picture description task is considered an effective way of obtaining a discourse sample whose key feature is the ability to retrieve appropriate lexical items. There is no consensus on findings showing that performance in content processing of spoken discourse deteriorates from the mildest phase of AD.ObjectiveTo compare the quantity and quality of discourse among patients with mild to moderate AD and controls.MethodsA cross-sectional study was designed. Subjects aged 50 years and older of both sexes, with one year or more of education, were divided into three groups: control (CG), mild AD (ADG1) and moderate AD (ADG2). Participants were asked to describe the "cookie theft" picture. The total number of complete words spoken and information units (IU) were included in the analysis.ResultsThere was no significant difference among groups in terms of age, schooling and sex. For number of words spoken, the CG performed significantly better than both the ADG 1 and ADG2, but no difference between the two latter groups was found. CG produced almost twice as many information units as the ADG1 and more than double that of the ADG2. Moreover, ADG2 patients had worse performance on IUs compared to the ADG1.ConclusionDecreased performance in quantity and content of discourse was evident in patients with AD from the mildest phase, but only content (IU) continued to worsen with disease progression.

ObjectivePurpose of this study is to evaluate the effects of training with six commercial Xbox KinectTM games on cognitive and motor aspects in Parkinson's disease (PD) patients and to compare the effects with a group of paired healthy subjects.MethodsThis study was a quasi‐experimental, controlled trial. Eight individuals with PD (mean age 68.9 ± 7.9) and eight older adults without PD, matched by age (mean age 67.6 ± 7.3) were enrolled in the study. Ten sessions of six Xbox 360 KinectTM commercial games were performed for 5 weeks. Subjects were evaluated before and 7 and 30 days after intervention. They were assessed using Montreal Cognitive Assessment, Frontal Assessment Battery (FAB), Timed Up and Go test, Ten Meters Walking test, and Balance Berg Scale. The Freezing of Gait Questionnaire, the Movement Disorder Society Unified Parkinson Disease Rating Scale, and the Parkinson's disease Questionnaire were also applied to PD group.ResultsSignificant improvement was found for cognitive aspects measured by Montreal Cognitive Assessment and FAB in both groups but without retention on FAB in PD group. No significant improvements were found for motor aspects in none group.ConclusionMotor–cognitive training using Xbox KinectTM games is a feasible resource to improve executive functions in PD patients and in older healthy people.

Introduction:Alzheimer’s disease (AD) is a degenerative syndrome that impairs cognitive functioning, including speech and language. Discourse can be used to analyze language processing, which is organized into microlinguistic and macrolinguistic dimensions.Objectives:To identify the occurrence of changes in the macrolinguistic dimension of oral discourse in AD patients. Design: This was developed as a cross-sectional study. Setting: Outpatient clinic of the Behavioural Neurology Division of São Paulo Federal University.Participants:121 elderly patients, with ≥ 4 years of education, divided into AD and comparison groups.Measurements:The subjects were asked to create a narrative based on seven figures that made up a story. The macrolinguistic aspects of the narratives were analyzed.Results:The performance of the AD group was inferior to that of the comparison group on content-related, no-content-related complete and incomplete propositions as well as macropropositions, main information units, appropriated local and global coherence, cohesive devices and all subtypes, cohesive errors and some of their subtypes. Global coherence, macropropositions and ellipsis subtype of cohesive devices were the variables that best differentiated the groups.Conclusions:Changes were observed in most aspects of the macrolinguistic dimension of oral discourse in patients with AD.

INTRODUÇÃO: Com o envelhecimento, pode ocorrer um declínio cognitivo. Sabe-se que melhorar o desempenho das funções cognitivas em idosos tem consequências importantes em sua qualidade de vida. A literatura sugere que o treinamento pode aprimorar as funções cognitivas em idosos saudáveis. OBJETIVO: Verificar o efeito de grupo de estimulação cognitiva em idosos saudáveis. MÉTODOS: Estudo longitudinal no qual foram avaliados 32 participantes escolarizados, com idade acima de 60 anos, divididos em dois grupos. O grupo-caso participou de 10 sessões de estimulação cognitiva em grupo. O grupo-controle foi formado por 15 indivíduos, com idade e escolaridade similares. A amostra foi avaliada antes e após a intervenção, através de uma versão adaptada da bateria CERAD, teste do relógio e check-list de queixas cognitivas. Foi usada uma análise descritiva, bem como o teste t-pareado, com o intuito de observar as diferenças entre os grupos após a estimulação. RESULTADOS: Não houve diferenças entre os grupos quanto à idade, gênero e escolaridade. Na avaliação inicial, os grupos não apresentaram diferenças no desempenho dos testes aplicados. Na testagem após a intervenção, foi observada melhora apenas no grupo-caso nas tarefas de nomeação, fluência semântica, fluência total (bateria CERAD) e desenho do relógio, assim como na check-list de queixas cognitivas. CONCLUSÃO: A estimulação cognitiva realizada diminuiu as queixas cognitivas dos idosos participantes e melhorou seu desempenho em testes cognitivos.
