Dementia Caused by Dural Arteriovenous Fistulas Reversed Following Endovascular Therapy

Abstract

We describe two patients who presented with dementia as the primary neurological manifestation of their dural arteriovenous fistula (dAVF). Although dementia is not the most common presentation for a dAVF, these cases show that obliterating the fistula can eliminate this dreadful manifestation. This awareness may facilitate the diagnosis of dementia in cases caused by dAVF and allow for a minimally invasive treatment that restores cognitive function back to baseline.
