Implication

Systematic review evaluates early deep brain stimulation's impact on motor outcomes in Parkinson's disease, indicating potential benefits over medical therapy alone.

Key Points

  • This research aims to assess whether early deep brain stimulation provides additional benefits when combined with best medical therapy in patients with early Parkinson's disease.
  • Conducted a systematic review and meta-analysis as per PRISMA guidelines.
  • Reviewed studies from MEDLINE, Embase, and the Cochrane Library (2002-2025) comparing early DBS with best medical therapy.
  • Focused on data from randomized controlled trials (RCTs) while including other study designs for context.
  • Pooled RCT data indicated a significant improvement in quality of life for patients receiving early DBS plus best medical therapy.
  • Motor function outcomes showed a trend favoring early STN-DBS, but results varied across studies and were not definitive.
  • Safety outcomes were comparable to standard DBS practices, suggesting early intervention may be safe.
