comorbidity

Pronunciation: koh-mor-BID-i-tee

The simultaneous presence of two or more medical or psychiatric conditions in a patient.

Full Definition

Comorbidity refers to the co-occurrence of multiple disorders or diseases in the same individual, either simultaneously or sequentially. In neuropsychiatry, comorbidity is extremely common, with many patients presenting with multiple psychiatric conditions or combinations of psychiatric and medical disorders. Understanding comorbidity patterns is essential for accurate diagnosis, treatment planning, and prognosis. Common examples include depression with anxiety disorders, substance use disorders with mental illness, and psychiatric conditions with neurological disorders.

Usage note: Distinguish from 'multimorbidity,' which refers to multiple conditions without specifying their relationship.
