Treating and overcoming co-occurring disorders can be complex and challenging for clinicians and clients. In the past, the field has attempted to treat co-occurring disorders separately, but evidence in recent years suggests that treating both disorders at the same time yields the best results. This presentation will offer an overview of the challenges and clinical issues that are present in helping people with dual diagnoses. Recommendations for assessment and treatment of co-occurring disorders will be provided, and a case example will be presented to assist with application of information.
