A study of 307 patients who had suffered an intracranial hemorrhage found 20% of the adults in that group, who were 49 or younger, had drugs in their system. The finding was presented at the American Stroke AssociationÃ¢â‚¬â„¢s annual stroke conference on February 17, in Kissimmee, Florida.
In a prepared statement, study author Dr. Michael Hoffman, director of the stroke program at Tampa General Hospital-University of South Florida, said:Ã‚Â “The dominant drug of abuse was cocaine, long recognized as a risk factor for intracerebral hemorrhage. Marijuana was another frequently abused drug, and is beginning to emerge as a risk factor for stroke. Amphetamines also were commonly abused.”
According to HealthDay News (2/17/06), intracerebral hemorrhage Ã¢â‚¬Å“is often linked with high blood pressure in people over age 50.Ã¢â‚¬Â
In this particular study, 57% of the patients studied, who were 50 and older, had high blood pressure, compared with 33% of those aged 18 to 49. Of the younger group of patients, 41% had malformed blood vessels in the brain, which increases the risk of an intracranial bleed.
The 30-day death rate for the 18-49 year-olds was 14.6%, compared with 21% for the 50-plus Ã‚Â age group.
