Understanding Bipolar Disorders & Co-Occurring Substance Abuse

Bipolar disorder is a serious, chronic illness that can significantly impair your ability to function normally in everyday life. Many people with bipolar disorder also have concurrent substance abuse issues which, in some cases, develop as a result of self-medicating mental health symptoms. When you have both a mental illness and a substance abuse problem, it is known as a co-occurring disorder (also called a dual diagnosis or comorbidity). Though both can be challenging to live with, there are integrated treatment options available for people with these disorders.

What Is Bipolar Disorder?Unhappy isolated woman at home

A serious mental illness characterized by unusual or severe changes in mood, energy level, and behavior, bipolar disorder has also been known as manic-depressive illness. People with bipolar disorder often experience distinct mood episodes during which they may display behavior that is markedly different from their normal personality; these episodes may last for 1 to 2 weeks or longer, in some cases.1

When bipolar disorder is severe, it can significantly interfere with your ability to maintain relationships, hold a job, or go to school, and you may need to be treated for it throughout your life to manage the symptoms. A 2011 analysis estimated that the projected lifetime risk of developing bipolar disorder is 2.4% in the world population.2

There are 4 basic types of bipolar disorder:1

Some say they feel extreme and unusual happiness, while others say they feel highly irritable. During a depressive episode, by contrast, people report feeling extremely fatigued, hopeless, or even suicidal.1

The American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) describes in more detail some of the signs, symptoms, and behaviors associated with the manic and depressive episodes seen with certain types of bipolar disorders:3

  • Manic episode characteristics:
    • Major depressive episode characteristics:

      There are several factors that may increase your risk of developing this disorder. Research suggests a strong genetic component for developing bipolar disorder, but the specific genes involved have not been conclusively identified. Genetics are, however, only one of several risk factors involved. Scientists know this because studies of identical twins have shown that when one twin is diagnosed with bipolar disorder, the second twin is sometimes spared.1

      The DSM-5 uses the term substance use disorder to talk about the diagnosis of drug and alcohol dependence and addiction. Depending on how many of the diagnostic criteria you meet in a 12-month period, your substance use disorder is categorized as mild, moderate, or severe. One of these criteria is that your drug or alcohol use causes significant problems in your life, such as mental or emotional distress or difficulty meeting your responsibilities at work, home, or school.3

      Other diagnostic criteria for substance use disorders include:3

      Addiction is relatively common in the United States. In 2015, approximately 20.8 million people, aged 12 or older, had a substance use disorder: 15.7 million people had an alcohol addiction and 7.7 million people had a drug abuse disorder.4

      Why Do They Occur Together?

      Mixing drugs and alcoholFor decades, national surveys have shown that substance abuse is more common among people with mental illnesses than among the general population. Likewise, the reverse is also true: people with substance abuse problems are more likely than other people to have a mental illness.5 In 2015, an estimated 8.1 million adults had both a mental illness and a substance use disorder, while 2.3 million adults had a severe mental illness coupled with a substance use disorder.4 These disorders may coexist for different reasons; for example, compulsive substance use behavior may arise as a result of repeated attempts to self-medicate distressing mental health symptoms with alcohol and drugs. However, these substances often end up exacerbating the mental illness rather than helping it.

      Those with bipolar disorder may be even more likely to develop a co-occurring substance abuse problem than people with other types of mental illnesses, according to the National Epidemiologic Survey on Alcohol and Related Conditions. Research indicates that 22–59% of people with bipolar disorder develop a drug or alcohol problem during their lifetime.6

      There are several theories as to why people with bipolar disorder are more prone to develop substance abuse problems. Some researchers have suggested it has to do with the overwhelming desire to self-medicate the symptoms of manic and depressive episodes. Others argue that bipolar disorder and addiction involve the same systems in the brain that regulate impulsivity, motivation, and the feeling of reward. Some researchers believe that bipolar disorder and addiction share the same environmental and genetic risk factors, which would place a person at a higher risk for developing both problems. It is also possible for a substance abuse problem to precede or lead to bipolar disorder.6

      Regardless of the cause, it is evident that co-occurring bipolar disorder and substance abuse can complicate diagnosis and treatment. Overlapping features, such as putting yourself in hazardous situations (substance abuse) and acting impulsively (bipolar), can lead to dangerous consequences and can make relapse more likely.

      Ways to Treat Both Disorders

      Supportive peers in a circleResearch evidence suggests that the best way to treat co-occurring disorders is to address them simultaneously. The previous protocol was to treat one at a time, which may have involved separate counselors or even separate facilities. Today, many addiction treatment centers are beginning to specialize in integrated treatment for dual diagnoses.6 Though it can be complex, treatment works best when it is tailored to meet your individual needs, symptoms, preferences, and responses to treatment—most approaches involve a combination of medicine and behavioral therapy.

      Examples of medications used to treat bipolar and substance abuse disorders include:6

      A few forms of behavioral therapy that have proven effective in dual diagnosis treatment include:6
