OBJETIVO: analisar as características clínicas e as condições mórbidas (CM) associados em uma amostra de pacientes com demência vascular (DV). MÉTODOS: foram estudados retrospectivamente 25 pacientes com diagnóstico de DV, estabelecidos com base critérios do grupo State of California Alzheimer´s Disease Diagnostic and Treatment Centers (ADDTC). Os dados clínicos e de neuroimagem e os exames laboratoriais foram computados para caracterização da amostra. RESULTADOS: a média da faixa etária foi de 68,7 ± 14,6 anos (64,0% homens), com escolaridade média de 5,2 ± 4,4 anos. A instalação súbita do quadro foi observada em 48,0% dos pacientes e a evolução em degraus e o curso flutuante, em 4,0% e 16,0% dos casos, respectivamente. Apresentavam déficit neurológico focal como sintoma inicial 48,0%, sendo constatado déficit ao exame em 80,0%. As principais CM foram: hipertensão arterial sistêmica (92,0%); hipercolesterolemia (64,0%); insuficiência coronariana (40,0%); tabagismo (40,0%); hipertrigliceridemia (36,0%); diabete melito (32,0%); doença de Chagas (8,0%). CONCLUSÕES: observou-se forte correlação entre DV e hipertensão e hipercolesterolemia. A presença de dois pacientes com doença de Chagas sugere que esta doença possa constituir possível fator de risco regional. OBJECTIVE: to analyze the clinical features and associated morbidity in a group of patients with vascular dementia (VD). METHODS: we retrospectively evaluated 25 patients with diagnosis of VD, based on the State of California Alzheimer´s Disease Diagnostic and Treatment Centers (ADDTC) criteria. Clinical and neuroimaging data and laboratory test results were obtained for the characterization of the sample. RESULTS: the mean age was 68.7 ± 14.6 years (64.0% men), with mean educational level of 5.2 ± 4.4 years. Sudden onset of symptoms was observed in 48.0% of patients and stepwise deteriorating and fluctuating courses being observed in 4.0% and 16% respectively. Focal neurologic deficits were the first symptom in 48.0%, with focal deficits being observed in 80% on examination. The main morbidity were: hypertension (92.0%); hypercholesterolemia (64.0%); coronary heart disease (40.0%); smoking (40.0%); hypertriglyceridemia (36.0%); diabetis mellitus (32.0%); Chagas' disease (8.0%). CONCLUSIONS: we observed strong association between VD and hypertension and hypercholesterolemia. The observation of two patients presenting Chagas' disease suggests that this endemic condition may be considered a possible regional risk factor
