Which clinical sign is NOT associated with Parkinson's disease?

Parkinson's disease is characterized by a specific set of motor symptoms, often referred to as the cardinal signs of the disorder. Among these signs, the pill-rolling tremor, difficulty in initiating movements (also known as bradykinesia), and the shuffling gait combined with cogwheel rigidity are all well-documented and frequently observed in patients with Parkinson's.

The phenomenon of increased facial movements due to tics is not associated with Parkinson's disease. In fact, this condition typically results in a reduced range of facial expressiveness, known as "masked facies," due to the rigidity and bradykinesia that affect the muscles involved in facial expressions. The tics and increased facial movements are more commonly linked to other neurologic conditions, such as Tourette syndrome, rather than Parkinson's disease. Thus, the presence of tics or increased facial movements does not align with the expected clinical presentation of Parkinson's, making this the correct identification of a sign that is not associated with the disease.
