Clinical challenges in the treatment of patients with posttraumatic stress disorder and substance abuse.

PURPOSE OF REVIEW: The aim of this article is to review the current literature on co-occuring posttraumatic stress disorder and substance-use disorder, with an emphasis on clinical aspects and emerging treatments. RECENT
FINDINGS: In clinical populations (focusing on either disorder), about 25-50% have a lifetime dual diagnosis of posttraumatic stress disorder and substance-use disorder. Patients with both disorders have a more severe clinical profile than those with either disorder alone, lower functioning, poorer well being, and worse outcomes across a variety of measures. In recent years, several promising treatment programs have been developed specifically for co-occuring posttraumatic stress disorder and substance-use disorder, with one model having been established as effective thus far.
SUMMARY: Comorbid posttraumatic stress disorder/substance-use disorder is a frequent diagnosis in clinical populations that severely affects course and outcome. Treatment approaches appropriate for this vulnerable population need to be evaluated further and implemented in routine practice.
