Comorbidity

 

What is a comorbidity?

A comorbidity is a primary disease or condition that co-occurs with but is often independent of, another disease or disorder. There are some conditions that are more likely than others to be comorbid with one another. As well as being a term that is used broadly in medicine, comorbidity is frequently referred to in psychology. In the context of psychology, comorbidity refers to more than one mental disorder that exists alongside a primary diagnosis, or the reason that a patient is referred to in the first place. An example of this in psychology would be a patient who may have schizophrenia combined with a personality disorder. This may be because the doctor is not able to tell much of a difference between the two conditions.

Multiple comorbidities, or multimorbidity, means having more than two illnesses or diseases at the same time. It's common and increases the complexity of disease management in patients.

When comorbidities are related to mental health, it's when there are mental and physical disorders within the same person. This is despite the chronological order in which they have occurred or the causes.
