Introdução: O Défice Cognitivo Ligeiro (DCL) é um processo patológico definido como um ponto intermédio entre o envelhecimento fisiológico e um estado de demência muito precoce. Entender a evolução natural deste estado, avaliando a deterioração cognitiva observada em pacientes com esta condição ao longo de um intervalo de dois anos pode ajudar a confirmar uma necessidade de intervenção terapêutica para evitar a sua progressão. Por outro lado, torna-se importante estudar a possibilidade de deteção rápida e mais precoce deste processo, através do eventual uso de outros testes como o Teste de Fluência Verbal e a Escala de queixas de memória subjetivas, mais práticos e simples que o MoCA, tradicionalmente usado para a sua deteção.
Materiais e Métodos: A amostra final foi composta por 16 indivíduos que participaram no Rastreio Geriátrico à Covilhã de 2016 e cujo resultado na escala MoCA permitia identificar casos de possível DCL. Foram reavaliados os valores de MoCA, bem como do Teste de Fluência Verbal para avaliar a evolução ao longo dos dois anos. Foi também aplicada a Escala de Queixas de Memória Subjetivas a estes indivíduos. A análise estatística dos dados foi feita com recurso a técnicas de análise estatística descritiva e inferencial.
Resultados: Observou-se entre as médias resultados do MoCA de 2016 e 2018 uma diminuição significativa de 2,688 ± 1,044 pontos (valor p=0,021). Em relação à fluência verbal, entre 2016 e 2018 verificou-se um aumento não significativo na média da pontuação no Teste de Fluência Verbal de 0,625 ± 0,779. A correlação entre os resultados do Teste de Fluência Verbal e do MoCA revelou-se positiva e fraca (Rs=0,451), sendo marginalmente significativa (valor-p=0,079). Não se encontrou qualquer correlação entre a Escala de Queixas Subjetivas de Memória e a pontuação do MoCA (Rs=0,095; valor-p=0,783).
Conclusão: Parece haver uma tendência, concordante com outros estudos, de um declínio cognitivo por parte das pessoas com Défice Cognitivo Ligeiro. Na população estudada, a fluência verbal e as queixas subjetivas de memória não se apresentaram significativamente correlacionadas com os resultados no MoCA. A realização de novos estudos com amostras de maiores dimensões parece interessante para melhor comprovar estes resultados.
Introduction: Mild Cognitive Impairment (MCI) is a pathologic process defined as an intermediate point between physiological aging and a very early state of dementia. Understanding this state’s natural evolution, by measuring cognitive decline observed in patients with this condition, in a two year interval, may help to confirm the necessity of therapeutic intervention, in order to avoid its progression. On the other hand, it becomes more important to study the possibility of earlier detection of this process, through the use of other tests, such as the Verbal Fluency Test and the Subjective Memory Complaints Scale, simpler and more practical, than the Montreal Cognitive Assessment Scale, traditionally used for its detection. Materials and Methods: The final sample was composed by 16 individuals that took part in the Geriatric Survey to Covilhã in 2016 and which results in the MoCA scale allowed for the establishment of a diagnosis of MCI. The values of MoCA, as well as those of the Verbal Fluency tests were reassessed, in order to evaluate the evolution in the course of the two years. The Subjective Memory Complaints Scale was also applied to these individuals. Statistical analysis was made with the program IBM SPSS Statistics version 25, with descriptive and inferential statistical analysis techniques. Results: Between the average results of the MoCA Scale of 2016 and 2018 it was observed a significant drop of 2,688 ± 1,044 points (p value=0,021). Regarding verbal fluency, between 2016 and 2018, a rise in the average result of 0,625 ± 0,779 was observed in the score of the Verbal Fluency Test, however it was not statistically significant. Correlation between the results of the Verbal Fluency Test and the MoCA Scale turned out weak (RS=0,451), this result being marginally significant (p value=0,079). No correlation was found between the Subjective Memory Complaints Scale and the MoCA scores (RS=0,095; p value=0,783). Conclusion: There seems to be a tendency, concordant with other studies, of a cognitive decline by the patients diagnosed with Mild Cognitive Impairment. In the present study, verbal fluency and subjective memory complaints did not show any significant correlation with the results in the MoCA scale. The realization of new studies with larger samples seems interesting to better prove these results.
