Use of Noninvasive Brain Stimulation in Parkinson's Disease
Parkinson's Disease
About this trial
This is an interventional basic science trial for Parkinson's Disease focused on measuring Parkinson, Transcranial direct current stimulation, Motor function, Cognitive function, Affective function
Eligibility Criteria
Inclusion Criteria:
- Diagnosis of "probable" PD, defined by the presence of at least 2 out of 3 cardinal motor features of PD (resting tremor, rigidity, and bradykinesia, plus a sustained and significant response to dopaminergic treatment);
- Age 40 or over;
- Taking stable medications for at least 30 days
Exclusion Criteria:
- Features suggestive of other causes of parkinsonism/ parkinson-plus syndromes;
- History of deep brain stimulation or ablation surgery, mass brain lesions;
- History of schizophrenia, schizoaffective disorder, other psychosis, bipolar illness, alcohol/drug abuse within the past year;
- Need for rapid clinical response due to conditions such as initiation, psychosis, or suicidality;
Contraindications to tDCS*
- metal in the head
- implanted brain medical devices
- Unstable medical conditions (eg. uncontrolled diabetes, uncompensated cardiac issues heart failure, pulmonary issues, or chronic obstructive pulmonary disease)
- Pregnancy
Sites / Locations
- Spaulding Rehabilitation Hospital

Left active anodal DLPFC
Right active anodal DLPFC
Sham tDCS
Open-Label Arm
We will place the anodal electrode on the left dorsolateral prefrontal cortex. Stimulation will be given at 2 mA for a total of 20 mins for 10 consecutive sessions (Monday through Friday).
We will place the anodal electrode on the right dorsolateral prefrontal cortex. Stimulation will be given at 2 mA for a total of 20 mins for 10 consecutive sessions (Monday through Friday).
Sham tDCS: For sham-controlled tDCS subjects, the same montage will be used; however current will be applied for only 30 seconds.
In addition to this study we will have an open label arm in which subjects who received sham stimulation through the course of the study will have the opportunity to receive active stimulation free of charge. The same parameters and identical procedures as is done in the original study will be used. Data will be collected as an open label, which will therefore provide additional information. Data obtained from this open label portion of the study will be kept separate.
