Insanity is a mental condition in which a person's thoughts and behaviors are so impaired they cannot distinguish reality from delusion. It is most commonly associated with schizophrenia, but there are several other forms of insanity including bipolar disorder, borderline personality disorder, and schizoaffective disorder. Symptoms may include disorganized speech, delusions, hallucinations, erratic behavior, and lack of motivation. Treatment typically involves a combination of medication, psychotherapy, lifestyle changes, and social support.
