Prevalence and risk factors in spontaneous intracerebral
hemorrhage and aneurysmal subarachnoid hemorrhage
Arch Neurol
(Aug) 53:734-730 1996

Risk factors for stroke include hypertension, anticoagulant therapy, and
alcohol ingestion. Juvela
et al, in a small study of patients admitted to a university hospital ER
analyzed risk factors
associated with patients hospitalized for hemorrhagic stroke. The twist of
this study was, that
intracerebral and subarachnoid bleeding were analyzed separately and found to
have different risk
factors. Briefly, cigarette smoking was associated with subarachnoid
hemorrhage, whereas hypertension, diabetes, anticoagulant treatment and
alcohol intake were associated with IC hemorrhage.
Comment: It seems that the sample size is really too small in this
study to study and compare risk factors meaningfully among these two types of
hemorrhagic "stroke"; however, the data are interesting.
