Two hundred and twenty-one Saudi patients admitted for stroke in King
Khalid University Hospital between 1982 and 1987 were evaluated clinic
ally and by laboratory and radiological investigations. Twelve patient
s were found to have leukoaraiosis on brain CT and a clinical picture
compatible with Binswanger disease (subcortical arteriosclerotic encep
halopathy). Arterial hypertension was present in all cases, seizure di
sorders in 25%, and dementia in 83%. The features of these cases are c
ompared with similar cases reported from other places. The importance
of control of hypertension in prevention of Binswanger disease is emph
asized.
