A disorder characterized by one or more of the following abnormal behaviors: delusions, hallucinations, disorganized thinking, disorganized or abnormal motor functioning, and negative symptoms. The individual often lacks insight into their condition. Psychotic disorders have diverse causes. Etiologies may include disease states such as schizophrenia, delirium, metabolic disorders, genetic disorders, medical disorders (e.g., tumors, epilepsy), and drug/medication reactions. The neurobiology and neuropsychology of more common psychotic conditions such as schizophrenia are well documented. Structural lesions have also been associated with rare psychotic conditions such as reduplicative paramnesia.
