Split-brain phenomena in anterior communicating artery aneurysm rupture: A case report

Psych J. 2017 Jun;6(2):120-136. doi: 10.1002/pchj.145.

Abstract

In 1976, a patient with an anterior communicating artery aneurysm (ACoAA) rupture (diagnosed on angiography) and sub-arachnoid hemorrhage (SAH) underwent serial neuropsychological testing revealing a classical anterior cerebral artery (ACA) spasm picture with severe anterograde amnesia of Korsakoff's type and dysexecutive syndrome. In addition, the patient demonstrated impaired hemispheric interaction with alien hand syndrome, dyscopia-dysgraphia, complete left ear neglect, and other, more complex, split-brain phenomena. He was evaluated by A. R. Luria in 1976. Following surgery the patient demonstrated gradual improvement.

Keywords: amnesia of Korsakoff's type; anterior communicating artery aneurysm (ACoAA) rupture; bisected brain syndromes; self-awareness.
