Introdução
O Défice Cognitivo Ligeiro (DCL) refere-se a um declínio cognitivo pouco proeminente, mas anormal para a idade, e pertence ao continuum entre o envelhecimento normal e a demência em estado inicial. A depressão é considerada um fator de risco para o desenvolvimento de demência. Torna-se por isso importante avaliar qual a evolução de doentes identificados com DCL e se o estado depressivo destes pode influenciar a possível evolução para um quadro demencial.
Materiais e Métodos
A amostra foi constituída por 16 idosos diagnosticados com DCL, há dois anos, no Rastreio à memória feito à população geriátrica da Covilhã e concelhos limítrofes. Foi usada a escala de Montreal Cognitive Assessment (MoCA) (versão 7.1) para a deteção e avaliação de alterações cognitivas e a Escala de Depressão Geriátrica de Yesavage versão curta (GDS) como ferramenta validada para o rastreio de depressão nos idosos.
Resultados
A pontuação do MoCA entre 2016 e 2018 diminuiu significativamente nesta população, em média, cerca de 2,69 ± 4,18 pontos (p=0,026), evidenciando um agravamento do défice cognitivo num período de dois anos. Cerca de 37,5 % dos voluntários evoluíram de pontuações compatíveis com Défices Cognitivos Ligeiros (DCL) para pontuações compatíveis com Demência. Os valores da GDS entre 2016 e 2018 aumentaram, em média, cerca de 0,19 ± 2,26 pontos, que corresponde a um ligeiro agravamento, não significativo, do estado depressivo (p=0,752). Encontrou-se uma correlação negativa fraca (r=-0,325), não significativa (p=0,219), entre a diferença das pontuações do MoCA de 2018 e 2016 e a diferença das pontuações da GDS de 2018 e 2016.
Conclusão
Os resultados refletem um agravamento significativo da função cognitiva num período de dois anos. Sabemos que os indivíduos com DCL estão em maior risco de evoluir para Demência a curto prazo comparativamente com a população geral. A correlação entre a evolução dos valores do MoCA e da GDS entre 2016 e 2018 mostrou-se negativa nesta população, mas sem significado estatístico. Assim, nesta população os sintomas depressivos poderão não ter influenciado significativamente a evolução do estado cognitivo.
Introduction Mild Cognitive Disorder (MCD) refers to a less prominent cognitive decline but abnormal for the subject´s age, and it belongs to the continuum between normal aging and early-onset dementia. Depression is considered a risk factor for developing dementia. It becomes important to evaluate if there is a relation between the progression of MCD into dementia and the progression of the depressive state. Materials and Methods Our sample consisted of 16 elderly individuals diagnosed with MCD, two years ago, in a memory screening done to the geriatric population that lived in Covilhã and nearby towns. The Montreal Cognitive Assessment Scale (MoCA) (version 7.1) was the method used for detection and evaluation of cognitive alterations and the Geriatric Depression Scale of Yesavage short version (GDS) was used as an authenticated tool for the depression screening in the elderly. Results MoCA results between 2016 and 2018 decreased significantly in this population, on average about 2,69 ± 4,18 points (p=0,026), showing aggravation of cognitive function in a two-year period. About 37.5 % of volunteers evolved from scores compatible with MCD to scores compatible with dementia. GDS values increased between 2016 and 2018 on average about 0,19 ± 2,26 points, which corresponds to a small aggravation, not significant, of a depressive state (p= 0,752). It was found a weak, not significant (p=0,219), negative correlation (r=-0,325) between the difference of MoCA’s scores within 2018 and 2016 and the difference of GDS scores of 2018 and 2016. Conclusion The results reflect a significant aggravation of the cognitive function in a two-year period. It is known that individuals with MCD have an increased risk of evolving into dementia in the short-term when compared with the general population. Correlation between the evolution of MoCA and GDS scores between 2016 and 2018 proved negative, but it was not significant. Thus, in our population depressive symptoms when evaluated with GDS may not be significantly influent in the evolution of the cognitive function.
