Use of Noninvasive Brain Stimulation in Parkinson's Disease

Not Applicable

Completed

• Conditions: Parkinson's Disease

• Registration Number: NCT01113086
• Lead Sponsor: Spaulding Rehabilitation Hospital

Brief Summary

The purpose of this research is to determine whether repetitive sessions of transcranial direct current stimulation (tDCS) to the prefrontal cortex can enhance the cognitive, affective and motor functioning of those with Parkinson's Disease.

In this study we will compare active tDCS with sham tDCS. Each subject will receive two consecutive weeks of stimulation (Monday through Friday). A battery of neuropsychological and affective tests will be administered throughout the duration of the study.

Detailed Description

Note that this study is a two-center study (the other center is Beth Israel Deaconess Medical Center - PI - Alvaro Pascual-Leone)

Primary Outcome Measures

Name	Time	Method
Evidence of improvement in general motor functioning in patients with Parkinson's.	after treatment (10 days) and at follow up (1 and 2 months after final stimulation)	Measured by various indexes, including Unified Parkinson's Disease Rating Scale (UPDRS), Simple Reaction Time, 4-Choice Reaction Time, Purdue Pegboard Test, Finger tapping, walking time, buttoning up and supination-pronation.

Secondary Outcome Measures

Name	Time	Method
Evidence of improvement in cognitive functioning in the areas of: executive function, reasoning, visuospatial ability, and working memory for patients with Parkinson's.	after treatment (10 days) and at follow up (1 and 2 months after final stimulation)	Will be measured by The Stroop Test, Hooper Visual Organization Test, Digit Span Test, Trail Making Test B.
