Throat clicking as the initial symptom of Parkinson's disease.

The presenting manifestations of Parkinson's disease (PD) are variable, but a majority of patients note tremor as the initial symptom. Others complain of slowing of movements, loss of dexterity, fatigue, or changes in handwriting as initial symptoms. We describe a patient who developed an unusual clicking sound emanating from his throat as the initial manifestation of PD.
