Early Substance Abuse Increases Likelihood of Developing Psychiatric Disorders in Late Twenties
Mental disorders are characterized by a variety of symptoms, such as abnormal moods or behaviour, excessive anxiety, and hallucinations. These symptoms often upset the person who experiences them and may interfere with the person’s ability to lead a normal life. The causes of most mental disorders are unknown. Some may arise from emotional conflicts or psychological stress. Others may result from learned behaviour patterns or are caused by biological defects in the brain. Many mental disorders are believed to result from a combination of emotional, social and biological factors.
Ways of defining and classifying mental disorders have changed over time. Older classification systems made a distinction between psychoses and neuroses. Psychoses are severe mental disorders in which a person loses touch with reality and experiences such symptoms as delusions and hallucinations. Neuroses are milder disorders marked by excessive anxiety. Other kinds of mental disorders include dementias and personality disorders. Dementias are abnormalities in thinking or behaviour caused by brain injury or brain deterioration. Personality disorders involve a tendency to act in socially unacceptable or self-defeating ways.
