RT Journal Article SR Electronic T1 Coital cerebral hemorrhage JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 2683 OP 2683 DO 10.1212/WNL.43.12.2683 VO 43 IS 12 A1 Finelli, Pasquale F. YR 1993 UL http://n.neurology.org/content/43/12/2683.abstract AB Sudden headache, confusion, and hemiparesis followed within minutes of late-morning sexual intercourse in a 39-year-old man. Imaging studies revealed hemorrhage into a vascular malformation. Sexual intercourse and circadian rhythm independently elevate blood pressure, and their concurrence may predispose to cerebral hemorrhage in the presence of a vascular malformation.
