In schizophrenia, the DSM-V divides catatonia into 3 kinds: malignant, akinetic, and hyperkinetic catatonia. The following are some of the symptoms of each form of catatonic schizophrenia: Akinetic: Also called stuporous catatonia, this disorder produces immobility, difficulty following directions, and echolalia (repeating someone else's words over and over). Hyperkinetic: Also described as enthusiastic catatonia, this condition causes bizarre, pacing and hyperactive behavior. This is a rarer variety than akinetic. Malignant: Also referred to as Stauder's lethal catatonia, this form causes high excitability that can be fatal.
