Definitions

A medical condition that disrupts a person's thinking, feeling, mood, and ability to relate to others and daily functioning is called a mental illness.

Mental illnesses are medical conditions that often result in a diminished capacity for coping with the ordinary demands of life. Serious mental illnesses include major depression, schizophrenia, bipolar disorder, obsessive compulsive disorder (OCD), panic disorder, post-traumatic stress disorder (PTSD), and borderline personality disorder. The good news about mental illness is that recovery is possible.

Mental illnesses can affect persons of any age, race, religion or income. Mental illnesses are not the result of personal weakness, lack of character or poor upbringing. Mental illnesses are treatable. Most people diagnosed with a serious mental illness can experience relief from their symptoms by actively participating in an individual treatment plan.
