Punding sévère au cours d'une maladie de Parkinson

Punding has only recently come to the attention of physicians through the first report in a parkinsonian patient, triggered by dopaminergic replacement therapy. The phenomenon was thought to be related to excessive dopaminergic stimulation of the limbic and associative pathways. The current mainstay of treatment is the reduction in the dose of dopaminergic medication or changing the presumed responsible drug, often a dopaminergic agonist. In this article, the authors review the epidemiology, pathophysiology and management of this curious phenomenon.
