Pattern of comorbidity with anxiety disorders?

• A. Schizophrenia.
• B. Major depressive disorder, other anxiety disorders, substance use disorders, and ADHD or OCD features.
• C. Dementia.
• D. Parkinson's disease.

Answer: (B)

The pattern most commonly seen with anxiety disorders involves a wide range of other mental health conditions, especially mood disorders, other anxiety disorders, substance use disorders, and attention-related or obsessive-compulsive features. This reflects how anxiety often coexists with depressive symptoms, how overlapping symptoms and shared risk factors link different anxiety disorders to one another, and how anxiety can contribute to self-medication with substances or interact with attention and compulsive symptoms in youth and adults. Because of these repeated coexistences, listing major depressive disorder, other anxiety disorders, substance use disorders, and ADHD or OCD features best captures the typical comorbidity profile described in clinical observations and research.

Schizophrenia, dementia, and Parkinson's disease can occur alongside anxiety, but they do not form the characteristic pattern of comorbidity that anxiety disorders most consistently exhibit across populations.
