Abstract
|
|
|
|
Levodopa treatment in Parkinson’s disease (PD) can cause a wide range of non-motor manifestations including poor impulse control and stereotyped behaviors. Punding is a term used to describe complex prolonged, purposeless and repetitive behavior in patients under dopamine replacement therapy. We report a 64-year-old PD patient who, concomitantly with self-increment of levodopa, developed punding behaviors in association with dopamine dysregulation syndrome. Gradual reduction of dopaminergic medication partially alleviated repetitive behavior over time.
