comorbidity
The simultaneous presence of two or more psychiatric or medical conditions in the same patient.
Full Definition
The co-occurrence of multiple disorders or conditions in a single patient, which is particularly common in psychiatric practice. Comorbidity can refer to psychiatric conditions occurring together (such as depression and anxiety) or psychiatric conditions alongside medical conditions. This term is essential in psychiatric documentation as it affects treatment planning and prognosis. Editors must distinguish this from 'co-occurring disorders' when referring specifically to substance use disorders alongside mental health conditions.
Usage
Usage note: Use 'co-occurring disorders' specifically when referring to substance use disorders with mental health conditions.
