Summary

This study tests whether a non-invasive brain stimulation technique called MRI-guided transcranial direct current stimulation (tDCS) can reduce depression and apathy in people with Parkinson's disease. Forty participants will receive either real or sham stimulation, and researchers will measure changes in mood, brain activity, and memory. It is an early-stage trial focused on symptom relief, not a cure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
transcranial direct current stimulation (tDCS) using a BIOPAC Stimsola device
What this could lead to
If it works, this could point toward a non-drug way to improve mood and thinking in people with Parkinson's disease.
What could go wrong
This is a small, early-stage study with only 40 people. The effects may be small or not last, and the sham group helps check if results are real.
