Cognitive and Functional Outcome After Aneurysmal Subarachnoid Hemorrhage

We reviewed all studies in the past 10 years that have focused on the effects of aSAH on cognition and day-to-day functioning.

Sixty-one empirical studies examining cognitive and functional outcome in patients with aSAH met inclusion criteria. Survivors of aSAH commonly experience deficits in memory, executive function, and language. These cognitive impairments interact to affect patients' day-to-day functioning, including activities of daily living, instrumental activities of daily living, return to work, and quality of life. Deficits in cognition and day-to-day functioning are further compounded by depression, anxiety, fatigue, and sleep disturbances.
