Abstract
We examined the prevalence of high ethanol intake, hypertension, and other risk factors for intracerebral hemorrhage in a case-control study of 24 young and middle-aged patients with intracerebral hemorrhage. We recorded ethanol consumption, history of hypertension, liver disease, cigarette smoking, and mild or severe coagulation disorder in each case of intracerebral hemorrhage and in 48 control patients matched by sex and age. In univariate matched analyses, the frequencies of high ethanol intake (p = 0.009), hypertension (p = 0.05), and coagulation disorder (p = 0.05) were higher in the cases than in the controls. After controlling for possible confounding factors, we found that high ethanol intake and hypertension were the only independent risk factors for intracerebral hemorrhage (p = 0.02 and p = 0.05, respectively). The hemorrhagic lesion found in cases with a high ethanol intake tended to be located in the cerebral lobes (p = 0.01), contrasting with the typical basal ganglia location of hypertensive hematomas (p = 0.009). We conclude that chronic, high ethanol intake should be considered as an important risk factor for lobar hematomas in young and middle-aged people.
