co-occurring disorders
The simultaneous presence of both a mental health disorder and a substance use disorder in the same individual.
Full Definition
Co-occurring disorders, also known as dual diagnosis, describes individuals who experience both mental health and substance use disorders concurrently. This term has largely replaced older terminology like 'dual diagnosis' or 'comorbid disorders' in contemporary behavioral health documentation. Co-occurring disorders require integrated treatment approaches that address both conditions simultaneously rather than treating them separately. The term appears frequently in treatment plans, diagnostic assessments, and program descriptions, and requires careful documentation of how each disorder influences the other and how treatment addresses their interaction.
Usage
Usage note: Hyphenated form preferred over 'dual diagnosis' in current practice; requires integrated treatment documentation.
