About this study

In plain language

This study tests whether repeated sessions of anodal transcranial direct current stimulation (tDCS) can help people with Parkinson’s disease (PD). This uses a weak electrical current on the left side of the brain that controls movement. Researchers want to see if it leads to lasting improvements in movement and less muscle tiredness.

The investigators hypothesize that multi-session anodal tDCS (atDCS) of the left primary motor cortex (M1) will induce long-lasting effects in improving motor function and reducing motor fatigue and fatigability in PD patients.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Have a doctor’s diagnosis of Parkinson’s disease and at least two signs: shaking, stiff muscles, slow movement, or trouble with balance.
  • Be able to understand the study and agree to take part.

Who can't join

  • Have dementia, with a score below 21 on the MoCA test of memory and thinking.
  • Use deep brain stimulation (DBS), an implanted device that sends electrical signals to the brain, to treat Parkinson’s disease.
  • Have psychosis, a condition that affects what you believe or sense is real.
  • Have multiple sclerosis, a disease that damages nerves.
  • Have had a stroke.
  • Have chronic obstructive pulmonary disease (COPD), a lung disease that makes breathing hard.
  • Have congestive heart failure (CHF), a condition in which the heart does not pump blood well.

Simplified for readability. The official criteria below are what the study team uses.
