Mental disorder

Mental disorder is the psychological inability to cope effectively with the demands of day-to-day life. Psychiatrists recognize two general types of mental disorder: neurosis (milder forms of illness, such as anxiety states) and psychosis (more serious forms of disturbance, in which individuals lose touch with reality). The organic and sociocultural bases of various mental disorders are disputed matters.


Mental Disorder is a health condition characterized by alterations in thinking, mood or behavior (or a combination of the three). Mental disorders are mediated by the brain and associated with distress and/or impaired functioning. They can be the result of family history, genetics or other biological, environmental, social or behavioral factors that occur alone or in combination.
