This is referred to as a dual-diagnosis, or sometimes a co-occurring disorder. Dual diagnosis/co-occurring disorders mean that you may have a psychiatric disorder and a substance abuse disorder. Dual diagnosis treatment units, like the Alcohol and Drug Inpatient Treatment Unit at Butler, are specifically designed to meet the needs of patients who may have significant active substance dependency, significant active psychiatric illnesses or both. ***Disclaimer: ****The content in this blog is for informational and educational purposes only and should not serve as medical advice, consultation, or diagnosis.
