Overview
The goal of this interventional study is to understand how the rhythmic abilities of individuals in the early stages of Parkinson's Disease (PD) are impacted by their levels of dopamine. The main questions it aims to answer are: * Does dopamine shelter the ability to generate and maintain a regular tapping rhythm in the presence of disrupting sensory information? * Does dopamine allow the adaptation of tapping speed in the presence of changing sensory information? * Is the engagement of the motor system useful to improve the detection of changes in the tempo of sensory information? Participants will be asked to perform a battery of simple rhythmic tasks On and Off medication to evaluate the effect of dopamine on their rhythmic skills.
Interventions
- Drug Withholding Levodopa
Participants will have to withhold Levodopa medication 12 h before one of two experimental sessions.
Primary outcome measures
- Changes in mean inter-tap intervals following Levodopa withdrawal during rhythmic tapping tasks. [Time frame: Between experimental sessions one and two, which will take place approximately one week apart.]
- Changes in constant error following Levodopa withdrawal during rhythmic tapping tasks. [Time frame: Between experimental sessions one and two, which will take place approximately one week apart.]
- Changes in asynchronies following Levodopa withdrawal during rhythmic tapping tasks. [Time frame: Between experimental sessions one and two, which will take place approximately one week apart.]
Secondary outcome measures (2)
- Impact of Levodopa withdrawal on motor symptoms severity scales. [Time frame: Between experimental Sessions one and two, which will take place approximately one week apart.]
- Impact of Levodopa withdrawal on motor symptoms severity scales. [Time frame: Between experimental sessions one and two, which will take place approximately one week apart.]
