ABSTRACT

OBJECTIVE:

To evaluate the prevalence of leukoaraiosis (LA) and its correlation with vascular risk factors and the cognitive performance of elderly patients.

METHOD:

78 patients were randomly selected and submitted to clinic-laboratorial evaluation for vascular risk factors. Two cognitive tests were performed. All patients were submitted to cranial computerized tomography (CT), which was analyzed in two situations the spontaneous and the directed way.

RESULTS:

There was no statistically significant difference between the prevalence of spontaneous and the directed diagnoses of LA (20.5 and 18 percent, respectively). The presence of LA was not significantly correlated with cognitive impairment. Only age was positively associated with LA.

CONCLUSION:

Cranial CT is a trustworthy method for the diagnosis of LA. Only age showed a positive association. No clinical implications were found, concerning the cognitive performance of the patients.
RESUMO

OBJETIVO:

Avaliar a prevalência da leucoaraiose (LA) em idosos e correlacioná-los com fatores de risco vasculares e seu desempenho cognitivo.

MÉTODO:

78 pacientes foram selecionados aleatoriamente e submetidos a avaliação clinico-laboratorial para fatores de risco vascular. Dois testes cognitivos foram realizados. Todos os pacientes foram submetidos a tomografia computadorizada (TC) de crânio, que foi analisada em duas situações de forma espontânea e dirigida.

RESULTADOS:

Não houve diferença estatisticamente significativa entre as formas de diagnóstico espontâneo e dirigido da LA (20,5 and 18 por cento, respectivamente). Com relação ao desempenho cognitivo, a presença da LA não determinou prejuízo significativo. Somente a idade mostrou associação positiva com a LA.

CONCLUSÃO:

A TC de crânio é um método confiável para o diagnóstico de LA. A idade foi o único fator de risco que mostrou associação positiva. Não houve prejuízo quanto ao desempenho cognitivo.
