Trial summary

Background: The way alcohol affects brain structure has been widely studied. But the way it affects all parts of the brain is still unknown. Researchers want to use magnetic resonance imaging (MRI) scans to study brain structure and function. Read more about this study

About this study

Official title: Cross-Sectional and Longitudinal Study of Structural Imaging

Background:

The way alcohol affects brain structure has been widely studied. But the way it affects all parts of the brain is still unknown. Researchers want to use magnetic resonance imaging (MRI) scans to study brain structure and function. They hope this will help them better understand changes that happen in brain regions during treatment of alcohol use disorders.

Objectives:

To study changes in the brain by using MRI in people with and without alcohol use disorders. To study how brain changes affect gait, balance, cognitive ability, and behavior. To see how the brain recovers when alcohol use stops.

Eligibility:

People with alcohol dependence who are currently hospitalized in a particular unit at NIH.

Healthy volunteers 30 60 years old without an alcohol use disorder.

Design:

Participants will be screened under a separate protocol.

Participants will give a urine sample for a drug test and pregnancy test at each study visit. They will also have to pass a breath alcohol test.

At the first visit, participants will have an MRI. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder.

They will do behavior and memory tasks outside the scanner.

They will have gait and balance tested. They will have to stand on both legs, stand on just one leg, and walk in a straight line. They will perform each task with eyes open, then with eyes closed.

They will have tests of memory, thinking, and problem solving.

Some participants will have a second visit. They will have another MRI and repeat some of the behavior and memory tasks.

Objective

The purpose of this protocol is to characterize cerebellar volumes and function in alcoholics and recovery of cerebellar volume and function during early abstinence. This study also investigates how cerebrocerebellar circuits contribute to cognitive and motor impairment in alcoholism.

Study Population

Healthy volunteers and Inpatient participants with alcohol use disorders.

Design

Participants will receive whole-brain structural imaging and assessment of cerebellar function at the time of admission and again at the time of discharge.

Outcome

The Primary outcome of this study is to assess recovery of cerebellar structure and function at the end of treatment compared to treatment entry measures.

Questions about this trial

What is this clinical trial studying?

An observational study of Chemically-Induced Disorders and Substance-Related Disorders, run by National Institute on Alcohol Abuse and Alcoholism (NIAAA) 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 11 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 6 May 2024. 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.

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.

What does the primary outcome measure?

The Primary outcome of this study is to assess recovery of cerebellar structure and function at the end of treatment compared to treatment entry measures. (time frame: Entry and End of Treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 May 2024.
