Effect of Alcohol on Tremors

Completed · Phase 2

Conditions studied: Tremor

In brief

Tremors are involuntary movements of a part or parts of the body that occur because of alternating contraction and relaxation of muscles. The causes behind most tremors are poorly understood. Some studies suggest tremors could be caused by abnormalities in a particular area of the brain called the olivary nucleus. Researchers believe that the cells making up the olivary nucleus may be responsible for generating a central rhythm of the body and may therefore also be responsible for the generation of tremors. Consumption of alcohol has been known to reduce tremors in some patients. Researchers believe that the alcohol may work directly on the cells of the olivary nucleus. As a result, researchers would like to determine the effects of alcohol on three different kinds of tremors (physiological, symptomatic palatal, and essential palatal).

Who can join

Age: any. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• A total of 20 subjects will be enrolled in the study. 10 normal subjects will be enrolled in the study. All will have an 8-12 Hz component of physiologic tremor as determined by neurophysiologic studies. Patients will have a prominent 8-12 Hz spike on accelerometry recordings that is associated with an EMG spike at the same frequency.
• 5 patients with essential palatal tremor and 5 patients with symptomatic palatal tremor will be included.
• All participants must be a minimum of 21 years of age.

You may not qualify if…

• The presence of any medical condition, such as liver disease, history or family history of alcoholism, that can reasonably be expected to subject the patient to unwarranted risk or compromise the value of the data.
• Any patient with pathologic tremor, such as parkinsonian rest tremor, essential tremor, or tremor secondary to medications or structural brain lesions.
• Any clinically significant laboratory abnormalities.
• Lack of effective contraception.
• Patients who are pregnant.
• Inability to understand the nature of the study or its procedures.
• Persons under the age of 21, who are not of legal age to consume alcohol in Maryland.
• Patients taking any psychoactive medications including certain cough or cold medicine preparations.
• No one will be excluded or discriminated against based on the grounds of race, creed, gender, color, or national origin. Every attempt will be made to include women and minorities in the study population.
