About this study

Official title: The Study of Appetite-Related Brain Activity With Functional Magnetic Resonance Imaging in Women With Anorexia Nervosa

This study will use functional magnetic resonance imaging to compare appetite-related brain activity in women with anorexia nervosa before and after receiving treatment for the disorder.

Read the detailed description

Anorexia nervosa (AN) is a serious eating disorder that is characterized by an extreme loss of appetite. People with AN view themselves as overweight and cannot bring themselves to eat, even though most are dangerously thin. Functional magnetic resonance imaging (fMRI) is a technique that can be used to determine which parts of the brain are activated by physical stimuli. When a certain stimulus is introduced, blood flow to the corresponding area of the brain increases. This increase in blood flow is depicted on the fMRI scan. A person with AN may have different responses to food when evaluated prior to treatment versus after treatment. This study will use fMRI to compare appetite-related brain activity in women with AN before and after receiving treatment for the disorder.

Participants in this study will undergo two fMRI scans. Participants with AN will have one scan before entering the "weight gain phase" of treatment for AN and another scan upon completion of treatment. Healthy volunteers will undergo scans during a similar time frame. Participants will not be allowed to eat from midnight on the night before the scan until after the fMRI procedure, but they may drink water. During the scan, participants will be shown various objects and real foods; they will also be asked to touch the objects and food with their eyes closed. Each visit will last approximately 45 minutes. Ear protectors will be provided to reduce scanner noise.

Questions about this trial

What is this clinical trial studying?

An observational study of Eating Disorders and Anorexia Nervosa, run by New York State Psychiatric Institute 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 7 inclusion and 12 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 19 Apr 2012. 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.

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 19 Apr 2012.
