Co-Occurring Disorders: Information and Treatment Guide
What Are Mental Health Disorders?
Mental health disorders are conditions that can profoundly affect thought, mood, and behavior.1,2 People with these disorders may experience severe distress and problems in their relationships, jobs, or other important areas of their lives.2
Mental health issues can range in severity.1 For example, the category of serious mental illness (SMI) includes conditions that are likely to result in significantly impaired functioning in most areas of a person’s life, while the category of any mental illness (AMI) may also include relatively more mild conditions.1,2
It’s common for people to experience an episode of mental illness at some point in their lifetimes. In fact, it is estimated that as many as 1 in 5 adults in the United States has struggled in the past year with some form of mental illness.1
What Is a Dual Diagnosis?
A dual diagnosis refers to the clinical situation in which a person has both an addiction and a mental illness at the same time.3 The term ‘dual diagnosis’ is not as widely used as it once was, with the phrase ‘co-occurring disorders’ becoming increasingly common.
Comorbidity is another term used to talk about addiction and mental health disorders. Like co-occurring disorders, it means two conditions present at the same time in the same person.3 However, the concept of comorbidity emphasizes the potentially adverse interaction of the two conditions.3 For example, addiction to certain drugs can cause or worsen existing mental health issues and, conversely, a mental illness may worsen the course of an addiction.
Mental Disorders That Co-Occur With Substance Abuse
Any mental illness can co-occur with drug or alcohol abuse, but certain mental health disorders co-occur at higher rates.
Mood and anxiety disorders are especially common among people with addictions.4,5 People with mood and anxiety disorders are 2x as likely to have a substance use disorder compared to people without these disorders.5
Are Developmental Disorders Considered Mental Disorders?
Developmental disorders begin in early childhood.2 They can affect a child’s emotional state, physical growth, and intellectual abilities.2 Some developmental disorders, like autism spectrum disorder, are also diagnosed as a mental disorder.2 When we talk about co-occurring disorders, however, we are not generally talking about developmental disorders.
Why Substance Use and Other Mental Disorders Co-Occur
Substance use and mental health disorders may co-occur for several reasons. First, many of the same risk factors contribute to both conditions.3 People with these specific risk factors have higher chances of developing co-occurring disorders. For example, trauma is one experience that significantly increases the risk of developing mental health issues, such as post-traumatic stress disorder (PTSD) and addiction.3
Second, having a mental health disorder can lead people to self-medicate, which involves using drugs or alcohol to cope with their symptoms.3,4 Some people may also turn to substances to ease the side effects of their psychiatric medications.3
People with mental health disorders may also experience changes in brain activity that can enhance the rewarding effects of drugs and reduce the awareness of negative consequences, making eventual addiction development more likely.3
Lastly, in some cases, addiction can lead to the development of mental health issues. Substance use can bring on changes to brain structure and function that may be similarly involved in the development of certain mental health disorders, like anxiety, depression, bipolar disorder, and schizophrenia.3 When these changes arise, a person may be more at risk of developing a mental health disorder.
Common Co-Occurring Disorders
The clinical presentation of different co-occurring disorders will vary. The following is a short list of some of common mental illnesses (and their main symptoms) that may occur alongside addiction.
Depression involves experiencing either depressed mood or loss of interest or pleasure, as well as some or all of the following symptoms at least over the course of a 2-week timeframe:2
- Depressed mood most of the day, nearly every day
- Significant weight loss/gain that is not attributed to changes in diet
- Fatigue nearly every day

- Muscle tension
- Being easily fatigued
- Difficulty falling or staying asleep
- Problems concentrating
Attention-Deficit/Hyperactivity Disorder (ADHD)
ADHD is defined as a persistent pattern of hyperactivity, impulsivity, and difficulty holding attention.2 People with this condition may find that their symptoms interfere with their functioning and developments and can include the following:2

Borderline Personality Disorder (BPD)
Personality disorders are long-standing patterns of thinking, feeling, and behaving that affect a person’s life and relationships.2 People with BPD may experience symptoms that include the following:
- Frantic efforts to avoid abandonment
- Feelings of emptiness
- Impulsivity regarding potentially self-damaging situations
- Mood reactivity
- Having unstable interpersonal relationships
- Unstable sense of self-image
Obsessive-Compulsive Disorder (OCD)
OCD is a type of anxiety disorder that involves obsessions and compulsions.2 Symptoms of this mental health condition can include the following:2
- Recurrent thoughts, urges, or images that are intrusive or unwanted
- Repetitive behaviors that an individual feels driven to perform and all rules surrounding the behaviors must be done perfectly
- Obsessions and compulsions consume a great deal of time or cause significant distress or impairment
Post-traumatic Stress Disorder (PTSD)
PTSD can develop after a person goes through a traumatic event or sees another person experience a traumatic event.2 Symptoms of PTSD often include the following:2
- Avoidance tactics in an effort to avoid upsetting memories about the event
- Intrusive memories of traumatic events
- Feelings of detachment from others
- Persistent inability to experience positive emotions
Schizophrenia is a serious mental illness that negatively affects people’s ability to care for themselves, keep up with their responsibilities, and have stable relationships.2 People with schizophrenia may experience symptoms that include the following:2
- Disorganized speech
- Disorganized behavior
- Difficulty showing emotional expression
Risks Factors for Addiction and Co-Occurring Disorders
Certain factors or experiences can increase the risk of developing a substance use disorder and/or another mental health disorder:3
- Genetics. Research suggests that somewhere around 40–60% percent of a person’s risk of developing addictions is attributable to genetic factors. Genetics can differentially affect how a person reacts to substances, how the body metabolizes certain drugs, and how an individual copes with stress.
- Trauma. People who have had traumatic experiences may develop post-traumatic stress disorder and turn to drugs and alcohol to self-medicate certain symptoms such as anxiety.
- Chronic stress. High levels of stress can affect activity in areas of the brain that are involved in controlling impulses and behavior. Stress may also disrupt normal dopamine signaling in the brain in a way that makes drugs feel more rewarding or pleasurable.
- Certain drugs of abuse. People using or withdrawing from certain drugs, such as cocaine, methamphetamine, and marijuana, may experience side effects, like depression, anxiety, or psychosis.5 Using these drugs can also worsen an existing mental health condition.
- Early drug use. Beginning to use drugs or alcohol as an adolescent increases the risk of developing both substance use disorders as well as mental illness.
Why Co-Occurring Disorders Require Specialized Treatment
People with co-occurring disorders can benefit from specialized treatment that addresses both issues at the same time. Integrative treatment is more effective than treating each condition alone.3 Studies have shown that treating only one condition can increase the risk of future relapses.4 Getting specialized treatment can ensure that you are getting the comprehensive help that you need to fully recover.
To find out whether a facility treats both conditions, ask their admissions team whether they provide treatment for co-occurring disorders. You can explain that you suffer from a mental illness and want to be sure that you receive treatment for both conditions.
The Dangers of Self-Medication
Self-medication is the act of using drugs or alcohol to cope with negative emotions or troubling symptoms.3,4 Drugs and alcohol can cause feelings of euphoria and relaxation, which people may seek out in an attempt to temporarily “numb” their emotions.
Even though self-medication can make a person feel better temporarily, it can cause more problems in the long run.4 People who self-medicate are more likely to develop a substance use disorder.3,4
Get Help for Mental Health and Drug Abuse Issues
Getting help for mental health and drug abuse issues at the same time can result in better treatment outcomes than treatment for only one condition.3 Laguna Treatment Hospital is one facility that provides comprehensive treatment for co-occurring disorders. They offer several different options to meet your needs:

Finding the Right Treatment Center for Addiction and Mental Health
It is important to find the right treatment center if you or a loved one is experiencing a co-occurring disorder. One of the most imperative factors to consider when making this decision is whether or not the treatment center offers dual diagnosis treatment. Additionally, you may want to consider factors such as levels of rehab care offered (e.g., inpatient addiction treatment, outpatient treatment) location, cost, and additional treatment options should you require continued care.
Dual Diagnosis Therapy
You will work closely with a team of professionals who will help create a treatment plan that meets your needs. This treatment plan can include a number of different evidence-based addiction therapies, including:
- Cognitive behavioral therapy (CBT)
- Motivational interviewing
- Contingency management
- Dialectical behavioral therapy (DBT)
Addiction Treatment Medications
While therapy is extremely beneficial and has proven to help treat the root causes of mental illnesses and substance use disorders, sometimes medication is also needed to help provide the most comprehensive care. Common medications in addiction treatment range from over-the-counter medications like Pepto Bismal, melatonin, and acetaminophen to prescription medications like disulfiram, methadone, naltrexone, and gabapentin.
