Abstract
Parkinson's disease is characterized by a variety of motor and non-motor symptoms. More than two hundred years have passed since its description, but we still discover its new manifestations. Abnormal behaviors include impulse control disorders, dopamine dysregulation syndrome, psychotic disorders and others. However, two new phenomena have been recently described in patients with PD. It can manifest in the form of doing inappropriate actions which patient doesn't recognize, or pronouncing/writing unsuitable words and phrases. Patients can't remember such episodes, but find «signs» of their unconscious activity or hear about it from attestors. This article represents a review of literature on unrelated communication interlude and automatic behavior in Parkinson's disease and discusses its possible reasons.
