Summary

This study tests whether D-serine, a dietary supplement, can slow the progression of Parkinson's disease. One hundred people with early-stage Parkinson's will receive either D-serine or a placebo for 58 weeks. Researchers will measure changes in symptoms and brain scans to see if D-serine protects nerve cells and improves quality of life.

D-serine (a dietary supplement)

What this could lead to

If it works, this could point toward a treatment that slows Parkinson's progression and reduces symptoms, helping people live better longer.
