ABSTRACT
OBJECTIVE:
Cerebrovascular disease (CVD) is associated with cognitive deficits. This cross-sectional study examines differences among healthy elderly controls and patients with vascular mild cognitive impairment (VaMCI) and vascular dementia (VaD) in performances on CAMCOG subscales.METHOD:
Elderly individuals (n=61) were divided into 3 groups, according to cognitive and neuroimaging status 16 controls, 20 VaMCI and 25 VaD. VaMCI and VaD individuals scored over 4 points on the Hachinski Ischemic Scale.RESULTS:
Significant differences in total CAMCOG scores were observed across the three groups (p<0.001). VaD subjects performed worse than those with VaMCI in most CAMCOG subscales (p<0.001). All subscales showed differences between controls and VaD (p<0.001). Performance on abstract thinking showed difference between VaMCI and controls (p<0.001).CONCLUSION:
CAMCOG discriminated controls from VaMCI and VaD. Assessment of abstract thinking may be useful as a screening item for diagnosis of VaMCI.RESUMO
OBJETIVO:
A doença cerebrovascular (DCV) associa-se a déficits cognitivos. Este estudo transversal objetiva examinar diferenças entre controles saudáveis idosos e pacientes com comprometimento cognitivo leve vascular (CCLV) e demência vascular (DV) nas subescalas do CAMCOG.MÉTODO:
Indivíduos idosos (n=61) foram divididos em 3 grupos, de acordo com o perfil cognitivo e com a neuroimagem 16 controles, 20 CCLV e 25 DV. Pacientes com CCLV e DV pontuaram acima de 4 pontos no Escore Isquêmico de Hachinski.RESULTADOS:
Diferenças significativas foram observadas entre os três grupos no resultado final do CAMCOG. Pacientes com DV obtiveram escores inferiores àqueles dos indivíduos com CCLV em quase todas as subescalas. Todas as subescalas mostraram diferenças entre DV e controles. O desempenho no item pensamento abstrato mostrou diferenças entre CCLV e controles.CONCLUSÃO:
O CAMCOG diferenciou controles de pacientes com CCLV e DV. A avaliação do pensamento abstrato pode ser útil para discriminar CCLV de controles.
