Co-occurring Disorders

Overview

Co-occurring disorders are defined as a person having one or more disorders relating to the use of alcohol and or other drugs as well as one or more mental disorder. Both drug use disorders and other mental illnesses are caused by over-lapping factors such as underlying brain deficits, genetic vulnerabilities, and/or early exposure to stress or trauma. Certain mental disorders are established risk factors for subsequent drug abuse and vice versa. Co-occurring disorders also implies interactions between the illnesses that affect the course and prognosis of both.

Population surveys show a high rate of co-occurrence between drug addiction and other mental illnesses. Adults with both substance use and severe mental health disorders is approximately 23% of the population or 69,000 people adjusted for Oregon population. The lifetime prevalence of substance use problems in people with severe mental illness is between 40 and 60%. They are more likely to be hospitalized and use emergency services, are highly vulnerable to housing instability, have high rates for homelessness, and in Oregon, people with COD die at an average age of 45.1 compared to 76.6. for the general population. In Oregon, 10,760 people received services in 2005 for both substance use and mental health.

AMH along with partners is improving services to Oregonians with co-occurring substance use and mental health disorders by:

  • Developing funding strategies
  • Developing competencies
  • Providing training and technical assistance to staff on program integration and evidence based practices
  • Conducting fidelity reviews of evidence based practices for the COD population
  • Revising the Integrated Services and Supports Oregon Administrative Rule

The high rate of co-occurrence between drug abuse and addiction and other mental disorders argues for a comprehensive approach to intervention that identifies, evaluates, and treats each disorder concurrently. Co-occurring substance use and mental health disorders is considered the expectation for both the addictions and mental health service providers.
