Diagnoses associated with dystonia include which of the following?

• A. Alzheimer's disease and Parkinson's disease
• B. Anxiety and depression
• C. PD, HD, MS, TBI, Birth injury/hypoxia, stroke
• D. Asthma and COPD

Answer: (C)

Dystonia arises when motor circuits, especially those involving the basal ganglia, are disrupted, leading to sustained or intermittent muscle contractions and unusual postures. It often appears as a feature or consequence of other neurological conditions, not just as an isolated disorder. The diagnoses that commonly show dystonia include Parkinson's disease, Huntington's disease, multiple sclerosis, traumatic brain injury, birth injury or hypoxic injury (cerebral palsy with dystonia), and stroke, all of which can damage motor networks and produce dystonic movements. In contrast, asthma and COPD are respiratory conditions with no direct link to dystonia, and while mood disorders like anxiety and depression can accompany movement disorders, they are not typical diagnoses associated with dystonia. Alzheimer's disease is primarily a cognitive disorder and does not typically present with dystonia as a defining feature.
