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

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.
