Substance use disorder (SUD) often co-occurs with post-traumatic stress disorder (PTSD), complicating treatment. Trauma-focused cognitive-behavioral therapy (CBT) has been identified as an effective intervention for reducing PTSD severity when delivered alongside SUD treatment. This approach is more effective than treatment as usual (TAU) or minimal intervention, particularly in reducing PTSD symptoms post-treatment and at follow-up . However, there is limited evidence supporting the use of non-trauma-focused interventions for this comorbidity.
Integrated psychosocial treatments that address both SUD and PTSD simultaneously have shown promising outcomes. These treatments often combine elements of trauma-focused therapy with strategies to manage substance use, providing a comprehensive approach to these co-occurring disorders.
For individuals with severe mental health disorders such as schizophrenia, certain antipsychotic medications have shown efficacy in treating SUD. Clozapine, in particular, has been found to be more effective than other antipsychotics for individuals with schizophrenia and SUD. Additionally, depot atypical antipsychotic paliperidone palmitate shows promise in this population .
Naltrexone is the most effective anti-craving agent for individuals with severe mental illness and comorbid alcohol use disorders. Opioid substitution therapy also yields favorable outcomes for those with comorbid opioid use disorders.
Non-invasive brain stimulation techniques such as rTMS and tDCS have demonstrated potential in reducing drug cravings and consumption. These methods are particularly effective when targeted at the Dorsolateral Prefrontal Cortex (DLPFC) . Short-term treatments with these techniques have shown beneficial effects, although further research is needed to extend these benefits over longer periods.
Deep Brain Stimulation (DBS) has shown moderate effectiveness in treating SUD, with significant improvements in clinical SUD scales and a low relapse rate. DBS appears to be more effective for patients over 45 years of age and for those with alcohol and opioid addictions compared to nicotine addiction.
Hospitalization presents a critical opportunity to initiate evidence-based treatment for opioid use disorder. Studies have shown that patients hospitalized with severe infections from injecting drugs are often willing to enter residential SUD treatment. This period can be leveraged to reduce in-hospital illicit drug use and improve long-term outcomes.
Effective treatment of substance use disorders requires a multifaceted approach that includes psychological, pharmacological, and neuromodulation interventions. Trauma-focused CBT and integrated psychosocial treatments are particularly effective for individuals with co-occurring PTSD and SUD. Pharmacological treatments such as naltrexone and clozapine show promise for those with severe mental health disorders. Neuromodulation techniques like rTMS, tDCS, and DBS offer additional avenues for reducing cravings and consumption. Hospitalization can serve as a pivotal moment for initiating treatment, highlighting the importance of timely and comprehensive care.
