Caused by abnormalities in the brain both structural and biochemical. Mental disorders include deficient or inappropriate social behaviours, illogical/incoherent/obsessional thoughts, inappropriate emotional responses (incl. depression, mania, or anxiety), delusions, and hallucinations. Literally means split mind but does not imply a split or multiple personality. Schizophrenia: a serious mental disorder characterized by disordered thoughts, delusions, hallucinations, and often bizarre behaviours; has three categories of symptoms: (1) positive, (2) negative, and (3) cognitive. Neologism: delusion: a belief that is clearly in contradiction to reality. Persecution: false beliefs that others are plotting and conspiring against oneself. Grandeur: false belief"s in one"s power and importance, like they think they have godlike powers or special knowledge no one else possesses. Control: the person believes that he or she is being controlled by others through such means as radar or a tiny radio receiver implanted in his or her brain: hallucination: perception of a nonexistent object or event.
