Co-occurring disorders, also known as dual diagnosis, happen when someone has both a mental health condition and a substance use disorder at the same time. At Homewood Health Centre, we treat these complex cases using methods based on scientific evidence. Our expertise in co-occurring mental health and addiction helps us provide complete care that fits each indivdual’s unique needs.
Key Takeaways: Co-occurring Disorders
- Co-occurring disorders affect about 50% of people with mental illness in Canada
- Mental health and substance use disorders are closely connected
- Common co-occurring disorders include depression, anxiety, PTSD, bipolar disorder, and ADHD
- Treatment that addresses both conditions at once often offers higher success rates
- Family support is crucial for recovery
In Canada, about half of the people with a mental illness also have problems with drugs or alcohol at some point. This shows how important it is to understand and treat both conditions together.
How Mental Health and Substance Use Are Connected
Mental health issues and substance use often go hand in hand. Sometimes, people use drugs or alcohol to feel better when they’re anxious or depressed. Other times, using substances can make mental health problems worse or even cause them. This is why at Homewood Health Centre, we focus on treating both issues together.

Our Integrated Mood, Anxiety and Addictions Concurrent Program is designed to help with these connected issues. We use an approach that looks at biological, psychological, social, and spiritual aspects of health. This means we treat the whole person, not just the symptoms.
Common Mental Health Disorders That Occur with Substance Use
Several mental health conditions often happen together with substance use disorders. Understanding these common combinations helps us diagnose and treat them better. Here are some of the most common:
Co-occurring Mental Health Disorders
- Depression and Substance Use: Half of people with depression also have substance use disorders.
- Anxiety Disorders and Addiction: 28% of people with drug problems and 16% with alcohol problems have anxiety disorders.
- PTSD and Substance Abuse: 46% of people with both drug and alcohol problems have PTSD.
- Bipolar Disorder and Substance Use: 35% of people with bipolar disorder also have substance use issues.
- ADHD and Substance Abuse: 24% of people with drug problems have ADHD.
Each of these combinations needs a special treatment approach. For example, a person with PTSD might drink alcohol to feel less emotional pain, while a person with ADHD might misuse stimulants to try to focus better. Understanding these patterns helps us create treatments that address both the mental health condition and the substance use problem at the same time.

Substance Use Disorders in Dual Diagnosis
While any substance can be part of a co-occurring disorder, some are more common than others. Alcohol use disorder is very common, often happening with depression or anxiety. Alcohol is easy to get and socially accepted, which can make it a common choice for people trying to feel better. Opioid addiction is another big concern, especially with the current opioid crisis in Canada. Opioids can be very appealing to people with mental health issues because they relieve pain and can make people feel good quickly.
Other substances often used in dual diagnosis cases include:
- Cocaine: Often used by people with mood disorders and ADHD
- Marijuana: Frequently used by people with anxiety or PTSD
- Benzodiazepines: Common for people with anxiety disorders and trouble sleeping
- Methamphetamine: Often used by people with depression and psychotic disorders
Understanding which substances are being used helps us create better treatment plans and address why people are using them.
Challenges in Diagnosing Co-occurring Disorders
Figuring out if an individual has co-occurring disorders can be tricky because the symptoms often look similar. For example, feeling tired from depression might look like being tired after using drugs, or feeling anxious from quitting a substance might look like an anxiety disorder. This is why we need experts to do a thorough check.

At Homewood Health Centre, we do complete assessments using proven tools and guidelines. Our team of experts takes time to understand each person’s situation to make sure we diagnose correctly and plan the right treatment. This thorough approach includes:
- Detailed medical and mental health history
- Complete physical examination
- Psychological testing
- Checking substance use
- Looking at social and environmental factors
By gathering all this information, we can get a clear picture of what’s going on and create a treatment plan that addresses all aspects of the dual diagnosis.
Integrated Treatment Approaches
We believe in treating co-occurring disorders at the same time for the best results. Our IMAAC program offers a range of therapies that have been proven to work, including:

Our approach also includes programs for overall wellness that address physical health, nutrition, and stress management. We know that recovery involves healing the whole person, not just treating specific symptoms.
