The aim of the study is to constitute a proof of concept study for a larger study investigating the effect of mindfulness on anxiety and agitation in Parkinson's disease (PD) based on the results of a preliminary feasibility.

Neuropsychiatric and behavioral non motor symptoms are common in PD often requiring hospitalization and/or specific drug management. Mindfulness-based stress reduction (MBSR) programs have proved to be efficacious in PD both for the management of motor and non-motor symptoms. This is however the case only in out-patients and by using standardized 8 weeks programs. The team has experienced in the hospitalization unit that methods derived from the MBSR program such as the "body scan", administered by the paramedical personnel, is of great help for the non-pharmacological management of anxiety and agitation in PD, avoiding physical contention in many cases. Based on this experience the study aims at evaluating the feasibility and preliminary efficacy of a simple and standardized administration of the "body scan" meditation in the management of anxiety and agitation in PD admitted in the unit since less than 48h.
