Smokers’ brains and strokesFrom the U.S. Department of Health and Human Services, I’m Ira Dreyfuss with HHS HealthBeat. Smoking raises your risk of a stroke. So does a family history of brain aneurysm – a weak spot in a blood vessel in the brain. But researchers say that, when a smoker has a family history, the stroke risk shoots higher. Daniel Woo of the University of Cincinnati saw that in data on people who had a stroke from a brain aneurysm and those who had not. The risk for smokers with a family history was six times that of the study’s baseline – nonsmokers without a family history of stroke or brain aneurysm. But Woo also says: [Daniel Woo speaks] ``If you were a former smoker – if you had smoked but you quit smoking – (you) cut your risk in half of having an aneurysm.’’ The study in the journal Neurology was supported by the National Institutes of Health.
