The Facts on Mental Illness
Mental Illness is Real, Common, and Treatable Many mental illnesses are caused by biochemical disturbances in the brain and others are triggered by exposure to an extremely stressful event. Mental illness is very common in the United States and internationally. An estimated 22.1 % of Americans ages 18 and older—about 1 in 5 adults—suffer from a diagnosable mental disorder in a given year. 4 of the 10 leading causes of disability in the U.S. are mental disorders: major depression, bipolar disorder, schizophrenia, and obsessive-compulsive disorder. Many people suffer from more than one mental disorder at a given time. Research by the World Health Organization has found that in the United States, mental disorders and suicide account for 15 % of the burden of disease--more than all cancers combined. Nationally, mental illness affects an estimated 40 million adults and up to 9 million children and adolescents. Suicide is the nation's eighth leading cause of death. There are also differences in the way mental illness occurs in men and women. All mental disorders, including those such as schizophrenia and bipolar disorder that affect males and females equally, occur at different ages for women and men, exhibit different types and patterns of symptoms, and require different treatment responses.
