Transcranial Direct Current Stimulation for Motor Function and Fatigue in PD

2 mA will be administered for 5 consecutive days for a duration of 20 minutes with electrode placement at the left dorsolateral prefrontal cortex.

For 30 seconds, the patient will experience a ramp up of the stimulation, after which point no stimulation will be transmitted for the remainder of the session. This will be administered for 5 consecutive days for a duration of 20 minutes with electrode placement at the left dorsolateral prefrontal cortex
