Comorbidity
In medicine, comorbidity refers to the simultaneous presence of two or more medical conditions in a person; often co-occurring (that is, concomitant or concurrent) with a primary condition. It originates from the Latin term morbus (meaning "sickness") prefixed with co- ("together") and suffixed with -ity (to indicate a state or condition). 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.
The term "comorbid" has three definitions:
Comorbidity can indicate either a condition existing simultaneously, but independently with another condition or a related derivative medical condition. The latter sense of the term causes some overlap with the concept of complications. For example, in longstanding diabetes mellitus, the extent to which coronary artery disease is an independent comorbidity versus a diabetic complication is not easy to measure, because both diseases are quite multivariate and there are likely aspects of both simultaneity and consequence. The same is true of intercurrent diseases in pregnancy. In other examples, the true independence or relation is not ascertainable because syndromes and associations are often identified long before pathogenetic commonalities are confirmed (and, in some examples, before they are even hypothesized). In psychiatric diagnoses it has been argued in part that this "'use of imprecise language may lead to correspondingly imprecise thinking', [and] this usage of the term 'comorbidity' should probably be avoided." However, in many medical examples, such as comorbid diabetes mellitus and coronary artery disease, it makes little difference which word is used, as long as the medical complexity is duly recognized and addressed.
Comorbidity is often referred to as multimorbidity even though the two are considered distinct clinical scenarios.
Comorbidity means that one 'index' condition is the focus of attention, and others are viewed in relation to this. In contrast, multimorbidity describes someone having two or more long-term (chronic) conditions without any of them holding priority over the others. This distinction is important in how the healthcare system treats people and helps making clear the specific settings in which the use of one or the other term can be preferred. Multimorbidity offers a more general and person-centered concept that allows focusing on all of the patient's symptoms and providing a more holistic care. In other settings, for example in pharmaceutical research, comorbidity might often be the more useful term to use.
In psychiatry, psychology, and mental health counseling, comorbidity refers to the presence of more than one diagnosis occurring in an individual at the same time. However, in psychiatric classification, comorbidity does not necessarily imply the presence of multiple diseases, but instead can reflect current inability to supply a single diagnosis accounting for all symptoms. On the DSM Axis I, major depressive disorder is a very common comorbid disorder. The Axis II personality disorders are often criticized because their comorbidity rates are excessively high, approaching 60% in some cases. Critics[who?] assert this indicates these categories of mental illness are too imprecisely distinguished to be usefully valid for diagnostic purposes, impacting treatment and resource allocation.[citation needed] Symptom overlap is a key component against DSM classification and serves as a note towards redefining criteria in disorders that the root cause may not be understood thoroughly. Regardless of criticisms, it stands that, annually[where?], up to 45% of mental health patients fit the criteria for a comorbid diagnosis. A comorbid diagnosis is associated with more severe symptomatic expression and greater chance of dismal prognosis. Certain diagnoses such as ADHD, autism, OCD, and mood disorders have higher rates of co-occurring or being prevalent in separate diagnoses. "Comorbidity in OCD is the rule rather than the exception" with OCD diagnoses facing a lifetime rate of 90%. With overlapping symptoms comes overlap in treatment as well, CBT for example is common for both ADHD and OCD with pediatric onset and can be effective for both in a comorbid diagnosis. OCD and eating disorders have a high rate of occurrence, it is estimated that 20-60% of patients with an eating disorder have OCD. More often, comorbidity complicates and can prevent treatment efficacy on a varying scale depending on the circumstances.
The term 'comorbidity' was introduced in medicine by Feinstein (1970) to describe cases in which a 'distinct additional clinical entity' occurred before or during treatment for the 'index disease', the original or primary diagnosis. Since the terms were coined, meta studies have shown that criteria used to determine the index disease were flawed and subjective, and moreover, trying to identify an index disease as the cause of the others can be counterproductive to understanding and treating interdependent conditions. In response, 'multimorbidity' was introduced to describe concurrent conditions without relativity to or implied dependency on another disease, so that the complex interactions to emerge naturally under analysis of the system as a whole.
Although the term 'comorbidity' has recently become very fashionable in psychiatry, its use to indicate the concomitance of two or more psychiatric diagnoses is said to be incorrect because in most cases it is unclear whether the concomitant diagnoses actually reflect the presence of distinct clinical entities or refer to multiple manifestations of a single clinical entity. It has been argued that because "'the use of imprecise language may lead to correspondingly imprecise thinking', this usage of the term 'comorbidity' should probably be avoided".
