Concurrent disorders is a term used to refer to co-occurring addiction and mental health problems. It covers a wide array of combinations of problems, such as: anxiety disorder and an alcohol problem, schizophrenia and cannabis dependence, borderline personality disorder and heroin dependence, and bipolar disorder and problem gambling.
Concurrent disorders are also sometimes called:
These problems can co-occur in a variety of ways. They may be active at the same time or at different times, in the present or in the past, and their symptoms may vary in intensity and form over time. People often ask, “Which came first: the mental health problem or the substance use problem?” This is a hard question to answer. It's more useful to think of them as independent problems that interact with each other.
There is no one symptom or group of symptoms common to all combinations. The combinations of concurrent disorders can be divided into five main groups:
Mental health problems and substance use problems can affect each other in several ways:
A person with concurrent disorders will often have more serious medical, social and emotional problems than if they had only one condition. Treatment may take longer and be more challenging.
Clients have the best success when both problems are addressed at the same time, in a coordinated way. The treatment approach usually depends on the type and severity of the person’s problems.

Integrated treatment is a way of making sure that treatment is smooth, coordinated and comprehensive for the client. It ensures that the client receives help not only with the concurrent disorders, but also in other life areas, such as housing and employment.
Ongoing support in these life areas helps clients to:
Integrated treatment works best if the client has a stable, trusting, long-term relationship with one case facilitator. This person is a health care professional, such as a case manager or therapist. Even though one person is responsible for overseeing the client’s treatment, the client may work with a team of professionals, such as psychiatrists, social workers and addiction therapists.
If all the treatment services aren't in one location, two or more therapists may work together to co-ordinate treatment, keeping in touch about the client’s progress. For example, a therapist in an addiction program might ask new clients questions to see if they also have mental health problems. If the clients do, the addiction program could either:
