Mental Health

Mental disorders affect thinking, emotions, and behaviors. They are often associated with distress and trouble functioning in social, work, or other daily activities. 

They are common. It was estimated that one in five American adults experienced mental illness in 2019 and one in 20 had a serious mental disorder.

There are many different types of mental disorders, including anxiety disorders, mood disorders, personality disorders, eating disorders, post-traumatic stress disorder, and psychotic disorders. 

Many factors can contribute to the risk of mental disorders. Genetics, life experiences, and biological factors can all play a role. There is no single cause.

Effective treatment for mental disorders generally involve a combination of medications, psychotherapy, and social support and education. These treatment options can help you live well and manage your symptoms.
