Long-Term Outcomes of Epilepsy After Aneurysmal Subarachnoid Hemorrhage

Epilepsy was diagnosed in 16% of 12-month survivors of aneurysmal subarachnoid hemorrhage, was the immediate cause of death in 21%, and was an independent risk factor for mortality in SAH survivors.

Aneurysmal subarachnoid hemorrhage (SAH) causes substantial long-term morbidity and higher mortality rates compared with the general population. Survivors are at increased risk for epilepsy, but the degree to which epilepsy contributes to excess mortality is unknown. To determine the prevalence of epilepsy and associated mortality in SAH survivors, researchers linked a long-standing, population-based registry of aneurysmal SAH patients in Eastern Finland with national medical and vital statistics. Epilepsy diagnosis was identified by national health insurance reimbursement for an antiepileptic drug (AED), which requires a neurologist to confirm the diagnosis.

Of 1059 patients enrolled in the registry from 1995 to 2007, 788 survived to 12 mon…
