Co-Occurring Disorders: Understanding the Connection Between Mental Health and Addiction
Learn what co-occurring disorders are, common types like mental health conditions and how BHG's treatment approach supports lasting recovery.
Co-occurring disorders affect millions of people, yet many don’t realize how closely mental health and substance use can be connected. For many people, recovery is not only about addressing substance use – it is also about understanding anxiety, depression, trauma or other mental health concerns that may be affecting daily life. When both conditions occur together, treating only one may leave important needs unmet and make recovery more challenging.
Understanding this connection between mental health and addiction is an important step toward finding effective, whole-person care that supports lasting recovery.
What Are Co-Occurring Disorders?
A co-occurring disorder is when a person has both a mental health condition and a substance use disorder at the same time. Also known as a dual diagnosis, these conditions can influence each other in different ways. Mental health symptoms can increase the risk of substance use, while substance use can worsen symptoms of anxiety, depression, PTSD or other mental health conditions.
Because these conditions are so closely connected, treating only one may leave the other unaddressed, making recovery more difficult. That’s why integrated treatment focuses on both substance use and mental health together, helping people build healthier coping skills and supporting long-term recovery.
Co-occurring disorders are common, treatable and not a personal failure. According to SAMHSA’s 2024 National Survey on Drug Use and Health (NSDUH), approximately 21.2 million adults had a co-occurring mental illness and substance use disorder.
That number matters because it reminds people they are not alone. With the right support, people can successfully manage both substance use and mental health in a way that feels more balanced and sustainable.

Common Types of Co-Occurring Disorders
Many mental health conditions can occur alongside substance use disorder. The experience is different for each person, but these are some of the most common examples.
Depression
Depression can include ongoing sadness, low energy, hopelessness or loss of interest in things that once mattered. When depression and substance use happen together, they can feed into each other. A person may use substances to numb emotional pain, while substance use may deepen feelings of isolation or sadness over time.
Substance use disorder and depression often require support that addresses both mood symptoms and recovery needs. Treating both together can help people feel more emotionally stable and better supported.
Anxiety Disorders
Anxiety disorders can involve intense worry, fear, panic or physical symptoms that make daily life harder. Some people use substances to calm anxiety or feel more in control, but that relief is usually temporary. Over time, substance use can make anxiety symptoms more difficult to manage.
Anxiety and substance use treatment works best when people learn practical coping skills while also receiving support for recovery. This may include counseling, medication support when appropriate and routines that reduce stress.
Post-Traumatic Stress Disorder (PTSD)
PTSD can develop after a traumatic experience and may involve flashbacks, nightmares, avoidance or feeling constantly on alert. PTSD and addiction recovery are often connected because substances may be used to manage distressing memories or emotional pain.
For people with opioid use disorder and mental health concerns like PTSD, care should feel safe, steady and supportive. Trauma-informed treatment helps people build coping strategies without judgment.
Bipolar Disorder
Bipolar disorder can involve shifts in mood, energy and activity levels. During certain mood episodes, a person may be more likely to take risks, use substances or struggle with sleep and routine.
When bipolar disorder and substance use happen together, support from a knowledgeable care team is especially important. Treatment may include therapy, medication management and structured recovery planning.
Personality Disorders
Personality disorders involve patterns in thoughts, emotions and behaviors that can make relationships, coping and daily stability more challenging. When substance use is also present, recovery may feel more complicated without consistent support.
With the right treatment, people can build healthier coping skills, strengthen relationships and feel more equipped to manage emotions.
How Co-Occurring Disorder Treatment Improves Recovery
Integrated care means treating substance use and mental health together instead of separating them into disconnected parts. This approach can lead to better outcomes because it recognizes that recovery is emotional, physical and practical.
Improves Mental and Emotional Health
When mental health symptoms go untreated, recovery can feel much harder. Depression, anxiety, trauma and mood changes can affect motivation, relationships and daily routines. Addressing these symptoms as part of care can help people feel more balanced and supported.
Reduces the Risk of Relapse
Mental health struggles can be strong relapse triggers. Stress, panic, grief, trauma symptoms or untreated depression can make substance use feel tempting as a way to cope. Co-occurring disorder treatment helps people build tools to manage emotions, reduce stress and recognize warning signs earlier.
Supports Long-Term Recovery
People are more likely to stay engaged in recovery when treatment fits their real needs. If someone receives support for both substance use and mental health, they may feel more understood by their care team. That connection can make it easier to keep appointments, follow treatment plans and ask for help when life feels difficult.
Encourages Whole-Person Healing
Recovery is not just about stopping substance use. It is about building a healthier and more stable life. Whole-person care looks at mental health, physical health, relationships, routines, housing, transportation and other factors that can affect recovery.
Tips for Managing Co-Occurring Disorders in Recovery
Managing co-occurring disorders takes support, consistency and patience. These steps can help make recovery feel more manageable.
Seek Integrated Care
Look for providers who understand both substance use and mental health. Integrated care means these needs are treated together, not as separate problems. BHG provides outpatient treatment for substance use disorder that can connect people with services designed around their recovery goals.
Stay Consistent with Treatment
Consistency matters. Attending therapy, keeping follow-up appointments and taking medications as prescribed can help create stability over time. If something feels hard to manage, talk with your care team before making changes on your own.
BHG’s counseling services can help people process emotions, build coping skills and stay connected to support.
Build a Support Network
Recovery can feel isolating, especially when mental health symptoms are part of the picture. Sharing your journey with trusted friends, family members or recovery groups can reduce that isolation. Support does not have to be perfect to be meaningful.
Reading patient recovery stories can also remind people that healing is possible and that recovery can look different for everyone.
Practice Self-Care
Self-care is not a reward you have to earn. It is part of maintaining stability. Sleep, nutrition, movement, quiet time and activities that reduce stress can all support mental health and recovery.
Small habits matter. Even a short walk, a regular bedtime or a few minutes of breathing can help create structure during stressful moments.
Maintain Your Recovery Routine
When life starts to feel more stable, it can be tempting to step away from routines that helped you get there. Staying connected to treatment, support and healthy habits can protect progress over time.
For people who need more structure, BHG’s intensive outpatient program may offer additional support while still allowing people to live at home and manage daily responsibilities.
What is Integrated Treatment for Dual Diagnosis?
Integrated treatment for dual diagnosis means a care team addresses substance use and mental health together in one coordinated plan. Instead of treating addiction first and mental health later, integrated care recognizes that both can affect recovery at the same time.
This type of care may include counseling, medication support, health screenings, recovery planning and practical resources. It can also include support for transportation, family responsibilities or other barriers that make treatment harder to maintain.
NIDA’s research on comorbidities explains that substance use disorders commonly occur alongside conditions such as anxiety disorders, depression, bipolar disorder and PTSD.
