What is NOT a symptom of drug-induced Parkinson's disease?

In the context of drug-induced Parkinson's disease, visual hallucinations are not a typical symptom associated with this condition. Drug-induced Parkinsonism primarily manifests through motor symptoms that resemble those of idiopathic Parkinson's disease, such as bradykinesia, tremors, and stiffness.

Bradykinesia refers to the slowness of movement and is a hallmark symptom of both Parkinson's disease and its drug-induced counterparts. Tremors, particularly resting tremors, are also commonly seen and are characteristic movements associated with Parkinsonian syndromes. Stiffness, or rigidity, is another key feature that reflects muscle stiffness and decreased mobility found in these conditions.

Visual hallucinations are more commonly associated with the progression of Parkinson's disease itself or as side effects from certain medications used to treat the condition, rather than being a direct symptom of drug-induced Parkinsonism. These hallucinations typically arise later in the disease process or as a complication of treatment, distinguishing them from the primary motor symptoms.
