Incidence and Effects of Sleep Apnea on Intracerebral Aneurysms

Incidence and Effects of Sleep Apnea on Intracerebral Aneurysms - IESA-Study

Patients with intracerebral aneurysm will be screened for sleep apnea using out of center polysomnography/polygraphy. Baseline blood pressure and medication will be assessed. Patients will be followed for up to 5 years to examine the increase in aneurysm size, rupture rate and changes in medication.
