Alcohol's effect on tremors put to the test
NCT ID NCT06403280
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how alcohol affects tremors in people with essential tremor, dystonia, and Parkinson's disease. 45 participants received either an alcoholic drink or a non-alcoholic placebo on separate days. Researchers measured tremor changes using a motion sensor and clinical exams. The goal was to see if alcohol's effect is real or just a placebo.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- alcohol (vodka)
- What this could lead to
- If it works, this could help doctors understand which tremor types respond to alcohol, potentially guiding future treatments.
- What could go wrong
- This is a small, completed study with only 45 participants. Results may not apply to everyone, and alcohol has known risks like intoxication and abuse potential.
