Dual diagnosis (also referred to as co-occurring disorders) is a term for when someone experiences a mental illness and a substance use disorder simultaneously. Either disorder—substance use or mental illness—can develop first. People experiencing a mental health condition may turn to alcohol or other drugs as a form of self-medication to improve the mental health symptoms they experience. However, research shows that alcohol and other drugs worsen the symptoms of mental illnesses.
The professional fields of mental health and substance use recovery have different cultures, so finding integrated care can challenging. A national effort led by psychiatrist Ken Minkoff helps systems integrate these cultures and services on every level of care.
How Common is Dual Diagnosis?
According to the National Survey on Drug Use and Health, 9.2 million U.S. adults experienced both mental illness and a substance use disorder in 2018.
Because many combinations of dual diagnosis can occur, the symptoms vary widely. Mental health clinics are starting to use alcohol and drug screening tools to help identify people at risk for drug and alcohol abuse. Symptoms of substance use disorder may include:
- Withdrawal from friends and family
- Sudden changes in behavior
- Using substances under dangerous conditions
- Engaging in risky behaviors
- Loss of control over use of substances
- Developing a high tolerance and withdrawal symptoms
- Feeling like you need a drug to be able to function
Symptoms of a mental health condition can also vary greatly. Warnings signs, such as extreme mood changes, confused thinking or problems concentrating, avoiding friends and social activities and thoughts of suicide, may be reason to seek help.
How is Dual Diagnosis Treated?
The best treatment for dual diagnosis is integrated intervention, when a person receives care for both their diagnosed mental illness and substance abuse. The idea that “I cannot treat your depression because you are also drinking” is outdated—current thinking requires both issues be addressed.
You and your treatment provider should understand the ways each condition affects the other and how your treatment can be most effective. Treatment planning will not be the same for everyone, but here are the common methods used as part of the treatment plan:
Detoxification. The first major hurdle that people with dual diagnosis will have to pass is detoxification. Inpatient detoxification is generally more effective than outpatient for initial sobriety and safety. During inpatient detoxification, trained medical staff monitor a person 24/7 for up to seven days. The staff may administer tapering amounts of the substance or its medical alternative to wean a person off and lessen the effects of withdrawal.
Inpatient Rehabilitation. A person experiencing a mental illness and dangerous/dependent patterns of substance use may benefit from an inpatient rehabilitation center where they can receive medical and mental health care 24/7. These treatment centers provide therapy, support, medication and health services to treat the substance use disorder and its underlying causes.
Supportive Housing, like group homes or sober houses, are residential treatment centers that may help people who are newly sober or trying to avoid relapse. These centers provide some support and independence. Sober homes have been criticized for offering varying levels of quality care because licensed professionals do not typically run them. Do your research when selecting a treatment setting.
Psychotherapy is usually a large part of an effective dual diagnosis treatment plan. In particular, cognitive behavioral therapy (CBT) helps people with dual diagnosis learn how to cope and change ineffective patterns of thinking, which may increase the risk of substance use.
Medications are useful for treating mental illnesses. Certain medications can also help people experiencing substance use disorders ease withdrawal symptoms during the detoxification process and promote recovery.
Self-Help and Support Groups. Dealing with a dual diagnosis can feel challenging and isolating. Support groups allow members to share frustrations, celebrate successes, find referrals for specialists, find the best community resources and swap recovery tips. They also provide a space for forming healthy friendships filled with encouragement to stay clean. Here are some groups NAMI likes:
- Double Trouble in Recovery is a 12-step fellowship for people managing both a mental illness and substance abuse.
- Alcoholics Anonymous and Narcotics Anonymous are 12-step groups for people recovering from alcohol or drug addiction. Be sure to find a group that understands the role of mental health treatment in recovery.
- Smart Recovery is a sobriety support group for people with a variety of addictions that is not based in faith.
