Mental disorders are classified as a psychological condition marked primarily by sufficient disorganization of personality, mind, and emotions to seriously impair the normal psychological and often social functioning of the individual. Individuals diagnosed with certain mental disorders can be unable to function normally in society. Mental disorders may consist of several affective, behavioral, cognitive and perceptual components. The acknowledgement and understanding of mental health conditions has changed over time and across cultures. There are still variations in the definition, classification, and treatment of mental disorders.
Treatments, as well as societies attitudes towards mental illnesses have substantially changed throughout the years. Many earlier treatments for mental illness were later deemed as ineffective as well dangerous. Some of these earlier treatments included trephination and bloodletting. Trephination was when a small hole was drilled into a person's skull to let out demons, as that was an earlier belief for mental disorders. Bloodletting is when a certain amount of blood was drained out of a person, due to the belief that chemical imbalances resulted in mental disorders. A more scientific reason behind mental disorders but both treatments were dangerous and ineffective nevertheless. During the 17th century however, many people with mental disorders were just locked away in institutions due to lack of knowledgeable treatment. Mental institutions became the main treatment for a long period of time. But though years of research, studies, and medical developments, many current treatments are now effective and safe for patients. Early glimpses of treatment of mental illness included dunking in cold water by Samuel Willard (physician), who reportedly established the first American hospital for mental illness. The history of treatment of mental disorders consists in a development through years mainly in both psychotherapy (Cognitive therapy, Behavior therapy, Group Therapy, and ECT) and psychopharmacology (drugs used in mental disorders).
