2001 MAR 22 - (NewsRx.com & NewsRx.net) -- Cigarette smoking increases the risk of brain hemorrhage, and the risk persists even after an individual quits smoking, evidence from a new study by University at Buffalo (UB) stroke researchers shows.
They also found that incidence is much higher in women who smoke or have quit smoking.
In their case-control study, they found that both current smoking and previous smoking were associated with a significantly increased risk of subarachnoid hemorrhage - bleeding into the space between the middle and inner linings of the brain.
The study results were presented recently at the American Heart Association International Joint Conference on Stroke and Cerebral Circulation.
"People need to be aware that once they take up smoking, they are facing a potentially irreversible risk for subarachnoid hemorrhage," said Adnan I. Qureshi, UB assistant professor of neurosurgery and lead author. "The study points out the important role of a potentially modifiable risk factor for brain hemorrhage. Unfortunately, the risk does not appear to change after quitting cigarette smoking. Therefore the only effective way to reduce the risk is to avoid smoking all together."
Less common than stroke caused by blocked arteries, subarachnoid hemorrhage accounts for 5% to 10% of strokes. It may occur without warning and often is fatal.
