What's your diagnosis? It has something to do with intoxication. I'll post the correct answer in a couple of days!
Correct answer: Marchiafava-Bignami syndrome. This is alcohol-induced corpus callosum necrosis, which can cause deficit of constructional ability, agraphia, mutism, ataxia, poor bimanual coordination, gaze apraxia/psuedohallucinated look, dysarthria, epilepsy, paucity of vocal and facial expression modulation, loss of consciousness and eventually coma.
