Análisis del estado cognitivo y su relación con la dependencia en las actividades de la vida diaria: un estudio transversal en pacientes con accidente cerebrovascular

Abstract

Objective

To analyse cognitive status in relation to activities of daily living (ADL) dependency in stroke patients.

Methods

A cross-sectional study was carried out. The Mini Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA) and the Barthel index were used to assess cognitive status and ADL, respectively. A Pearson and Spearman correlation was used considering the normality of the data in cognitive status.

Results

62 patients were evaluated. The most impaired domains were associated with writing and drawing in the MMSE (mean = 24.9 ± 4.1) and language, visuospatial/executive function, and memory in the MoCA (mean = 18.3 ± 5.6). The ADLs with most dependency on the Barthel index (mean = 78.1 ± 14.0) were eating, dressing/undressing, bathing, and going up and down stairs. On the other hand, the ADL dependency showed a correlation with the MMSE (Rho = .3) and the MoCA (r = .2). In addition, MMSE was correlated with activities including dressing/undressing (Rho = .3) and bathing (Rho = .3) and MoCA with transfer from chair to bed (r = .2).

Conclusions

The domains with the highest cognitive impairment were related to memory and visuospatial/executive function. The correlations reflect that stroke survivors with greater cognitive impairment show greater ADL dependency.
