Summary

This study tests whether a mild electrical brain stimulation technique called tDCS can improve swallowing difficulties in people with Parkinson's disease. 58 participants will receive either real or sham tDCS alongside standard swallowing therapy. Researchers will measure changes in swallowing function and brain activity using video X-rays and brain scans.
