Trial summary

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. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Who may be able to join

  • 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.

Who cannot join

  • 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.

About this study

Official title: Effect of Alcohol on Physiologic and Pathologic Tremors

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).

Read the detailed description

The pathophysiology and anatomical basis of most tremors remains poorly understood. One particular theory of essential tremor, the olivary hypothesis, has gained support from various studies. These studies point to the olivary nucleus as possible central rhythm generator. Cells in the olivary nucleus show spontaneous rhythmic discharges that can be suppressed by alcohol. Since alcohol is known to suppress tremor in some patients with essential tremor, one can theorize that it is through its effect on the olivary nucleus; that is, the inferior olive is the generator of the tremor. Given this assumption, we intend to study the effect of alcohol on three different kinds of tremor: the 8-12 Hz component of physiological tremor, symptomatic palatal tremor and essential palatal tremor. Our hypothesis is that the central generator of each of these types of tremor lies in the inferior olive and that the ingestion of alcohol should reduce the amplitude of the tremor, similar to the effect of alcohol seen in essential tremor.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Alcohol in people with Tremor, run by National Institute of Neurological Disorders and Stroke (NINDS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00001925, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
