Daily life a risk for brain aneurysm rupture

DRINKING coffee is riskier than nose blowing or having sex when it comes to triggering the rupture of an intracranial aneurysm (IA).

Research suggests about 2% of the population has an IA, although they rarely rupture, say Dutch researchers who have provided the first attempt to quantify the population attributable risk of daily living activities linked to IA rupture.

Drinking coffee topped the list, implicated in 10.6% of IA ruptures, followed by vigorous exercise (7.9%), nose blowing (5.4%), sex (4.3%), straining to defecate (3.6%) and drinking cola (3.5%).

Being startled (2.7%) or angry (1.3%) were also significant, the researchers said.

“Our data support the view that a sudden and short-lasting increase in blood pressure caused by daily activities is a relevant pathophysiological pathway for aneurismal rupture,” they wrote.

“Some triggers are modifiable… reducing caffeine consumption or treating
