Trial summary

The purpose of this study is to investigate thought processes and neural mechanisms that may contribute to the development of habitual behaviors.

About this study

The purpose of this study is to investigate thought processes and neural mechanisms that may contribute to the development of habitual behaviors. The investigators hypothesize that patients with AN will perform differently than people without eating disorders on a series of neuropsychological tasks and will show different neural activation patterns in functional neuroimaging scans.

Read the detailed description

Patients with Anorexia Nervosa (AN) have extreme difficulty changing their eating behavior, even when they express desire for change. These behaviors seem to override all other potential responses, and can appear perseverative, or habitual. The purpose of this study is to investigate thought processes and neural mechanisms that may contribute to the development of habitual behaviors. The investigators hypothesize that patients with AN will perform differently than people without eating disorders on a series of neuropsychological tasks and will show different neural activation patterns in functional neuroimaging scans.

Questions about this trial

What is this clinical trial studying?

An observational study of Anorexia Nervosa, run by New York State Psychiatric Institute.

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 8 inclusion and 13 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 15 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.

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?

Neuropsychological functioning (time frame: pre- and post-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 15 Aug 2014.
