What characterizes Medication-induced Parkinsonism?

Medication-induced Parkinsonism is characterized by symptoms that resemble those of Parkinson's disease. This condition arises as a side effect of certain medications, particularly antipsychotics and other drugs that affect dopamine pathways in the brain. The key symptoms usually include tremors, rigidity, bradykinesia (slowness of movement), and postural instability, all of which are hallmark features of Parkinson's disease.

The reason this choice is correct lies in its clear connection to the physiological effects of the medications involved. These medications can lead to a decrease in dopamine activity, which is crucial for coordinating smooth and controlled movements. Hence, the symptoms that emerge mimic those of Parkinson's disease itself due to the disruption of dopamine transmission.

Other options do not align with the characteristics of medication-induced Parkinsonism. Highly elevated mood and energy are indicative of mood disorders or stimulant effects, while episodes of severe anxiety and panic are associated with anxiety disorders rather than movement disorders. Fluid retention and swelling pertain more to cardiovascular or kidney issues and are not typical symptoms associated with Parkinsonism.
