Learn About Co-Occurring Disorders

Learn About Co-Occurring Disorders 

Co-occurring disorders refers to the presence of two or more conditions that interact with and often intensify one another. Rather than existing in isolation, these conditions become interconnected, influencing the onset, severity and course of each other, making it essential to receive integrated treatment to find lasting healing. 

Co-occurring disorders can take various forms. Some individuals may suffer from symptoms of a mental health disorder and a substance use disorder, which is also referred to clinically as dual diagnosis. Others may struggle with multiple substance use disorders or with multiple mental health disorders.  

Research consistently shows that treating only one condition at a time while overlooking the symptoms of other concerns leads to poorer treatment outcomes and higher rates of relapse. At our treatment center in Tucson, Arizona, our interdisciplinary team is equipped to address the full complexity of co-occurring disorders within a single, cohesive course of care. We are dually licensed to treat individuals who are suffering from mental health concerns, addictions or both, which allows us to shape treatment based on a whole-person approach. 

Signs & Symptoms of Co-Occurring Disorders

Signs & Symptoms of Co-Occurring Disorders 

Because co-occurring disorders involve more than one condition, the signs and symptoms a person displays can vary widely depending on the specific combination of diagnoses. Symptoms may overlap, mask one another or appear to shift over time, which is one reason why receiving a thorough clinical assessment and comprehensive treatment is so important. 

Common signs that a person may be suffering from co-occurring disorders include: 

Behavioral symptoms 

  • Using substances to cope with emotional distress or other symptoms of mental health disorders 
  • Impulsive or risky behaviors 
  • Withdrawal from social activities or relationships 
  • Difficulty taking care of daily responsibilities or sudden, unexpected changes in daily routines 
  • Struggling to perform at work or succeed professionally 
  • Repeated attempts to stop using substances without success 

Emotional symptoms 

  • Persistent sadness, hopelessness or feelings of emotional numbness 
  • Intense or difficult-to-control fear, worry or anxiety 
  • Rapid or unpredictable mood shifts 
  • Irritability, anger or heightened emotional reactivity 
  • Feelings of guilt, shame or worthlessness 

Cognitive symptoms 

  • Difficulty concentrating or making decisions 
  • Racing thoughts or mental fog 
  • Impaired judgment 
  • Intrusive or distressing thoughts 
  • Overwhelming cravings for drugs or alcohol 

Physical symptoms 

  • Changes in sleep, appetite or weight 
  • Fatigue, low energy or chronic physical exhaustion 
  • Ongoing or unexplained physical pain 
  • Physical tension, restlessness or psychomotor changes 
  • Headaches, sweating or nausea 
  • Drug or alcohol withdrawal 

If you recognize these symptoms in yourself or someone you care about, reaching out for a professional evaluation is an important step to take.  

Effects of Co-Occurring Disorders

Effects of Co-Occurring Disorders 

When someone is suffering from co-occurring disorders and does not receive treatment, the effects can extend into nearly every area of their life. Mental health disorder symptoms may become more severe, substance use may escalate and the interactions between the two can make daily functioning increasingly difficult. 

Common effects of untreated co-occurring disorders include: 

  • Worsening depression, anxiety, trauma-related distress or mood instability 
  • Greater risk for medical complications and the need for detox or acute stabilization services 
  • Strained relationships and loss of trust  
  • Disruption at work, job loss and chronic unemployment 
  • Ongoing cycles of relapse and emotional pain 
  • Overall reduced quality of life 

The good news is that co-occurring disorders are treatable. With the right level of care — one that addresses all conditions simultaneously through a coordinated, individualized approach — healing is possible.
