(noun)
 The presence of one or more disorders (or diseases) in addition to a primary disorder or disease.
Examples of comorbidity in the following topics:
- 
Tenosynovitis- This condition often presents with comorbid tendinitis, which is the inflammation of the actual tendon itself.
 
- 
Fibromyalgia- It is frequently comorbid with psychiatric conditions such as depression and anxiety, and stress-related disorders such as post-traumatic stress disorder.
 
- 
Neurodevelopmental Disorders: Autism and ADHD- Many people with ADHD also show comorbidity: they develop secondary disorders in addition to ADHD .
 
- 
Introduction to Biomedical Therapies- For example, studies comparing an antidepressant to a placebo may use an eight-week double-blind parallel design and include subjects with major depression, but without any other medical or psychiatric comorbidities.
- Effectiveness studies, on the other hand, are often larger, naturalistic studies that attempt to approximate "real-world" conditions by studying patients who may have psychiatric and medical comorbidities and by relying on broader outcome measures for assessing response.
 
- 
Cluster C: Avoidant, Dependent, and Obsessive-Compulsive Personality Disorders- Various medications may also be used to treat comorbid (co-occurring) disorders, such as depression or anxiety.
- Some, but not all, studies have found high comorbidity rates between the two disorders, and both may share outside similarities (for example, rigid and ritual-like behaviors).
 
- 
Abnormal Psychology- The diagnostic manual includes a total of 237 specific diagnosable disorders, each described in detail, including its symptoms, prevalence, risk factors, and comorbidity.
 
- 
Feeding Disorders- However, many have proposed other mental disorders that are comorbid with ARFID—indeed, symptoms of ARFID are usually found with symptoms of other disorders.
 
- 
Generalized Anxiety Disorder- A particular challenge in treating GAD is its high comorbidity with other disorders, such as depression and substance abuse; it can be difficult in therapy to make progress with multiple issues simultaneously.
 
- 
Cluster A: Paranoid, Schizoid, and Schizotypal Personality Disorders- STPD is rarely seen as a primary reason for treatment in a clinical setting, but it has high rates of comorbidity with other mental disorders (i.e., it is often part of a dual diagnosis of STPD and a second disorder).
 
- 
Classifying Abnormal Behavior: The DSM- Many diagnoses are so similar that there is a high rate of comorbidity between disorders.
