Adult psychiatry is a specific sub-specialty relating to the evaluation, diagnosis and treatment of adults with psychiatric disorders.

Behavioral health disorders affect about one in five American adults, according to the Substance Abuse and Mental Health Services Administration (SAMHSA). Although many of these disorders are common and can be serious, they are treatable – and recovery is possible. 

Behavioral health disorders include mental health and substance use disorders:

  • Mental health disorders cause changes in a person’s mood, thinking, or behavior. They affect how well people function in relating to others and making decisions in work, school, or home life. Mental health disorders can occur once, return intermittently, or continue over time.
  • Substance use disorders develop when continued alcohol or drug use significantly impairs a person’s ability to function well at work, school, or home. These disorders can be mild, moderate, or severe and can cause health problems or disability.
