Definition of mental illness plus the five major categories of mental illness and misconceptions about mental illness.
A mental illness is a disease that causes mild to severe disturbances in thinking, perception and behavior. If these disturbances significantly impair a person's ability to cope with life's ordinary demands and routines, then he or she should immediately seek proper treatment with a mental health professional. With the proper care and treatment, a person can recover and resume normal activities.
Many mental illnesses are believed to have biological causes, just like cancer, diabetes and heart disease, but some mental disorders are caused by a person's environment and experiences.
The five major categories of mental illness:
Anxiety disorders are the most common mental illnesses. The three main types are: phobias, panic disorders, and obsessive-compulsive disorder. People who suffer from phobias experience extreme fear or dread from a particular object or situation. Panic disorders involve sudden, intense feelings of terror for no apparent reason and symptoms similar to a heart attack. People with obsessive-compulsive disorder try to cope with anxiety by repeating words or phrases or engaging in repetitive, ritualistic behavior such as constant hand washing.
Mood disorders include depression and bipolar disorder (or manic depression) symptoms may include mood swings such as extreme sadness or elation, sleep and eating disturbances, and changes in activity and energy levels. Suicide may be a risk with these disorders.
Schizophrenia is a serious disorder that affects how a person thinks, feels, and acts. Schizophrenia is believed to be caused by chemical imbalances in the brain that produce a variety of symptoms including hallucinations, delusions, withdrawal, incoherent speech and impaired reasoning.
This group of disorders includes diseases like Alzheimer's which leads to loss of mental functions, including memory loss and a decline in intellectual and physical skills.
Anorexia nervosa and bulimia involves serious, potentially life-threatening illnesses. People with these disorders have a preoccupation with food and an irrational fear of being fat. Anorexia is self-starvation while bulimia involves cycles of bingeing (consuming large quantities of food) and purging (self-inducing vomiting or abusing laxatives). Behavior may also include excessive exercise.
