Conversion hysteria can occur traumatically during combat or post-traumatically, years later. Conversion hysteria can manifest itself as an inability to know where one is or to function at all, often accompanied by aimless wandering around the battlefield with complete disregard for evident dangers. Upon occasion the soldier becomes amnesiatic, blocking out large parts of his memory. Often, hysteria degenerates into convulsive attacks in which the soldier rolls into the fetal position and begins to shake violently.
