We report two patients with avoidance of swallowing saliva despite intact swallowing functions. One, with mild, de novo Parkinson's disease, had a fear that his saliva was contaminated and would harm him.

He had a lesion involving the left pallidum. Both appeared obsessed with the idea of saliva contamination and both expectorated compulsively, presenting obsessive-compulsive disorder (OCD) symptoms. OCD-like behavior may be induced in association with pathological conditions in which aberrant basal ganglia functions are present.
