CNS volume 13 supplement 6 Cover and Front matter

Substance abuse and mental disorders commonly occur together and place an incalculable burden on individuals, families, and society at large. Left untreated, co-occurring psychiatric and substance use disorders may result in troubled and unproductive lives, as this comorbidity is associated with underachievement or failure at work and school, poor health, problems fulfilling family responsibilities, abuse, violence, and legal difficulties. Co-occurring disorders frequently have a complex and bidirectional relationship and may require longitudinal, repeated assessments to establish correct diagnosis. A number of reliable instruments have been developed to improve screening and assessment in both primary care and mental health settings, but controversy persists regarding the best approach to treatment. A fundamental issue, for example, is whether to treat a mood or an anxiety disorder in the presence of ongoing alcohol or drug abuse. Although recent recommendations suggest that concurrent substance abuse should not impede treatment of psychiatric symptoms, more evidence is required to facilitate decision making during acute treatment. Further, relapse and recurrence are common among individuals with co-occurring disorders, and the issue of long-term treatment typically needs to be addressed. Optimal patient management requires a collaborative effort by mental health care professionals, addiction specialists, and primary care physicians. Therefore, it is important that physicians who care for this patient population weigh the most recent evidence on effective and integrated treatment of individuals with co-occurring mood, anxiety, and alcohol use disorders.
