Perturbed behavior

Perturbed behavior in Trementia and primarly Catathymia is primarly characterized by a form of formal thought disorder, which affects behavior instead of speech.
In the middle of a multistage activity, the person may inappropriately switch to another activity and may or may not return to what they were doing, derailments in such behavior includes dancing, jumping, wandering and impulsive reactions, inability to inhibit emotions, self-speaking, impulsive joking and lying, impulsive silliness, pseudophilosophical brooding and obnoxiousness. 
Symptoms can degenerate into a form of "possession by another spirit" and self-control being entirely lost to an "alien mind", the person may behave as if they were possessed by a demonic spirit, complications include indiscriminate mass murder, thief, burning things or suicide or symptoms similar to disorganized behavior in schizophrenia.
The disorganization syndrome in Schizophrenia is thought to be related to perturbed behavior in Catathymia, both exhibit purposeless and bizarre behavior.
