ResumoObjetivo: É evidente o envelhecimento da população e a prevalência elevada da depressão nos idosos. Propõe-se, nesta investigação, compreender a relação entre a sintomatologia depressiva e a evocação de memórias autobiográficas nos idosos, pois estudos nesta área têm mostrado que a sobregeneralização das memórias autobiográficas apresenta-se como uma característica estável que funciona como marcador e preditor da depressão. Método: A amostra é constituída por 50 idosos, com idades entre os 65 e os 92 anos. Foram divididos por dois grupos: Sem Sintomatologia Depressiva (n = 32) e Com Sintomatologia Depressiva (n = 18). Aplicou-se um questionário sociodemográfico, o Montreal Cognitive Assessment (MoCA), o Inventário da Depressão de Beck (BDI), o Inventário de Ansiedade Estado e Traço (STAI) e a Tarefa de Memória Autobiográfica. Resultados: Constata-se a inexistência de uma sobregeneralização das memórias autobiográficas nas pessoas com sintomatologia depressiva. Os idosos sem sintomatologia depressiva não diferem significativamente dos idosos com sintomatologia depressiva na evocação de memórias autobiográficas específicas, categóricas e alargadas, de valência emocional positiva e negativa e nos tempos de latência. Conclusão: Levanta-se a hipótese da inexistência de diferenças significativas poderem ser explicadas pela severidade ligeira dos sintomas depressivos apresentados pela maioria dos idosos com sintomatologia depressiva. Sugere-se a expansão do conhecimento nesta área que permita a prevenção e o desenvolvimento de intervenções mais adequadas aos idosos. Palavras-Chave: idosos, sintomatologia depressiva, memórias autobiográficas AbstractAim: The continuous progression of population aging and the high prevalence of depression in the elderly are evident. This investigation aimed to study the relationship between depressive symptomatology and the recall of autobiographical memories in the elderly, because studies in this field have shown that overgeneralization of autobiographical memories was presented as a stable feature that works both as a marker and predictor of depression. Method: The sample is composed of 50 elderly, aged between 65 and 92 years. They were divided into two groups: Without Depressive Symptomatology (n = 32) and With Depressive Symptomatology (n = 18). A sociodemographic questionnaire, Montreal Cognitive Assessment (MoCA), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI) and the Autobiographical Memory Test were applied. Results: The absence of an overgeneralization of autobiographical memories in people with depressive symptomatology was observed. Older people without depressive symptomatology did not differ significantly from the elderly with depressive symptomatology in the evocation of specific, categorical and extended autobiographical memories, positive and negative emotional valence and latency times. Conclusion:The hypothesis that the inexistence of differences can be explained by the slight severity of depressive symptoms for most seniors with depressiv...

Flexibility decline contributes to similarity of past and future thinking in Alzheimer's disease

2015

View full text Add to dashboard Cite

A striking similarity has been suggested between past and future thinking in Alzheimer’s Disease (AD), a similarity attributable to abnormalities in common modular cognitive functions and neuroanatomical substrates. This study extends this literature by identifying specific executive function deficits underlying past and future thinking in AD. Twenty-four participants with a clinical diagnosis of probable (mild) AD and 26 older controls generated past and future events and underwent tests of binding and the executive functions of flexibility, inhibition, and updating. AD patients showed similar autobiographical performances in past and future event generation, and so did control participants. In each group, the similarity of past and future thinking was predicted by flexibility. Furthermore, AD patients with low flexibility showed higher similarity of past and future thinking than those with high flexibility. These findings are interpreted in terms of involvement of the hippocampus and frontal lobes in future thinking. Deficits in these brain regions in AD are likely to compromise the ability to recombine episodic information into novel and flexible configurations as scenarios for the future.
