Comorbidity

In medicine, comorbidity refers to the simultaneous presence of two or more medical conditions in a person; often co-occurring with a primary condition. It originates from the Latin term morbus prefixed with co- ("together") and suffixed with -ity. Comorbidity includes all additional ailments a person may experience alongside a primary diagnosis, which can be either physiological or psychological in nature. In the context of mental health, comorbidity may refer to the concurrent existence of mental disorders, for example, the co-occurrence of depressive and anxiety disorders. The concept of multimorbidity is related to comorbidity but is different in its definition and approach, focusing on the presence of multiple diseases or conditions in a person without the need to specify one as primary.
