Co-Occurring DisordersIntegrated Dual Diagnosis Care
When trauma coexists with substance use, eating disorders, or other mental health conditions, treating one without the other leads to incomplete recovery. At Reconnect, we address the whole picture.
Understanding Co-Occurring Disorders
Co-occurring disorders, also known as dual diagnosis, refers to the presence of two or more mental health or behavioral health conditions occurring simultaneously. In the context of trauma treatment, this most often means that trauma or PTSD coexists alongside substance use disorders, eating disorders, or other psychiatric conditions, including dissociative presentations where signs of dissociative identity disorder need careful assessment, and how did is diagnosed follows a structured, longitudinal process rather than a single visit.
These conditions are not separate problems that happen to overlap. They are deeply interconnected. Substance use, disordered eating, and other compulsive behaviors frequently develop as attempts to manage the overwhelming emotions, intrusive memories, and nervous system dysregulation caused by unresolved trauma. When treatment only addresses the surface behavior without resolving the underlying trauma, relapse is common.
At Reconnect, our integrated approach treats the root cause and the co-occurring symptoms simultaneously, giving you the best chance at lasting recovery.
Co-Occurring Conditions We Treat
We specialize in treating trauma alongside these commonly co-occurring conditions, including dissociative identity disorder treatment, addressing how each condition influences and reinforces the other.
Trauma & Substance Use
Up to 75% of people who survive traumatic experiences report problematic alcohol or drug use. Substances become a way to numb flashbacks, quiet hypervigilance, manage insomnia, or simply feel normal. We address the trauma driving the substance use rather than treating addiction in isolation.
Trauma & Eating Disorders
Eating disorders and trauma are closely linked, with disordered eating often serving as an attempt to control overwhelming emotions or regain a sense of agency over one's body. Restriction, bingeing, and purging can be understood as survival strategies rooted in traumatic experience.
Trauma & Process Addictions
Compulsive behaviors around gambling, spending, internet use, or other activities can function similarly to substance use, providing temporary escape from emotional pain and nervous system dysregulation caused by trauma.
Trauma & Depression
Depression frequently co-occurs with PTSD and complex trauma. The emotional shutdown, hopelessness, and withdrawal of depression are often direct consequences of living in a state of chronic traumatic stress.
Learn MoreTrauma & Anxiety Disorders
Anxiety disorders and trauma share overlapping neurobiological pathways. A trauma-sensitized nervous system is primed for anxiety, and anxiety symptoms can trigger trauma responses, creating a cycle that requires integrated treatment.
Learn MoreTrauma & Dissociative Disorders
Dissociation is a hallmark of severe trauma responses. When combined with other conditions, it can complicate treatment and make stabilization more challenging, requiring the careful, phased approach our clinicians specialize in.
Learn MoreOur Integrated Approach
The key word in our treatment of co-occurring disorders is integration. Rather than treating trauma in one track and the co-occurring condition in another, our clinicians address both simultaneously within every session and every modality.
This means your EMDR sessions can process the traumatic memories that drive substance cravings. Your DBT skills training can address both emotional dysregulation from trauma and the urges associated with disordered eating. Your somatic therapy work can release the physical tension that fuels both anxiety and compulsive behaviors.
- Address Root Trauma — we identify and process the traumatic experiences that created the need for the co-occurring behavior, removing the fuel that keeps the cycle running.
- Build Regulation Skills — through DBT, mindfulness, and somatic practices, we help you develop healthier ways to manage the intense emotions and physical sensations that previously drove problematic behaviors.
- Heal the Whole Person — our treatment considers your relationships, self-concept, physical health, and life circumstances, not just the diagnostic labels.
Why Integrated Treatment Matters
Traditional treatment models often separate trauma therapy from addiction treatment or eating disorder treatment. This approach has significant limitations:
- Treating addiction without trauma leaves the root cause intact
- Processing trauma without addressing substance use can trigger relapse
- Separate providers may offer conflicting recommendations
- Integrated treatment shows significantly better outcomes
Recommended Programs
Co-occurring disorders typically require a higher level of care, especially in the early stages of treatment. We recommend our more intensive programs for the structure and support needed.
Partial Hospitalization Program (PHP)
Our most recommended level of care for co-occurring disorders. PHP provides the daily structure, clinical intensity, and comprehensive support needed when managing multiple conditions simultaneously. Includes individual therapy, group process, skills training, and coordination with outside providers.
Intensive Outpatient Program (IOP)
An excellent option for those who have achieved initial stabilization or whose co-occurring symptoms are moderate. IOP provides robust treatment multiple times per week while allowing greater independence. Ideal as a step-down from PHP or for clients with strong external support systems.
