Sponsor: Medical University of Graz
Conditions: Essential Tremor, Dystonia, Parkinson Disease
Interventions: Alcoholic drink, Placebo drink
Countries: Austria
The aim of this interventional study is to compare the response to alcohol in patients with essential tremor (ET), essential tremor plus (ETplus), dystonic tremor (DT), tremor associated with dystonia (TaD) and tremor in Parkinson´s disease (PD). The main question to be answered is: • Is there a difference in the objective alcohol responsiveness of patients with ET, DT, TaD and PD? Participants will receive either vodka with rum-flavoured orange juice with a target blood alcohol of 0.4 ‰ or a non-alcoholic rum-flavoured orange juice (vice versa on the second study day). Before and 30, 60 an 120 minutes after the study drink the participants will undergo a clinical examination of the tremor and accelerometry will be performed. Researchers will compare alcohol and placebo in a randomized cross over way to see if the effect of alcohol on tremor exceeds the placebo effect.
