Study design

This pilot randomized 48 people with Parkinson’s disease to a remote Breath, Sound, and Meditation program or a wait-list group. The intervention included six weeks of guided practices. The Parkinson Anxiety Scale was assessed at baseline and at weeks 6, 12, and 18. The week-6 comparison was against the wait-list group before it crossed over.

What it found

After six weeks, anxiety scores fell more in the intervention group; the reported between-group difference was about five points. Only 31% met the authors’ practice-compliance definition. This is an anxiety result, not evidence of better memory or cognition.

Limits and interpretation

The pilot was small and used a wait list rather than an active attention control. Dropout and adherence limit certainty about effect size and durability. It supports further testing for anxiety symptoms, but does not show disease modification or effects on cognitive decline.
