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

  • Subjects will be recruited through advertisements within Bethesda and surrounding communities.
  • All subjects must be right-handed.
  • For experiments #1 and 2, subjects will be 20-40 years old.
  • For study #3, subjects will be 45-75 years old.
  • For experiment #2, all subjects will be mothers with a non-adopted child aged 6-12 years old.
  • For experiment #3, subjects in the bereaved group will have become spousally bereaved within the past 6 months.

Who cannot join

  • Subjects will be excluded if they have a history of significant medical disorders (including learning disabilities, seizures, history of head trauma, hypertension, or cerebrovascular disease) or psychiatric disorders, including substance abuse. (An exception to this is that bereaved subjects in experiment #3 will not be excluded if they meet DSM-IV criteria for major depressive disorder (non-psychotic), adjustment disorder with depressed mood, or bereavement, as long as their current Hamilton-D score is less than 13).
  • Subjects will also be excluded if they take any prescribed medications (including birth control pills), if they are pregnant, or if their vision is inadequate to see the visual stimulus.
  • In addition, subjects in experiment #2 will receive a DICA-P (Diagnostic Interview for Children and Adolescents, Parent Version), and will be excluded if their child meets diagnostic criteria for a psychiatric illness.

About this study

This study uses functional magnetic resonance imaging (fMRI) to look at brain activity while patients view pictures of people's faces that they are familiar with or have emotional attachment to.

The functional MRI (fMRI) procedure allows researchers to "see the brain at work." It uses the same powerful magnetic fields and weak electromagnetic radiation (radiowaves) as standard structural MRI. However, functional MRI can also show areas of increased blood flow, which relates to increased activity by brain cells.

This research study builds on previous studies that identified specific areas of the brain that are activated by visual stimuli showing faces. However, previous research used anonymous faces as stimuli. This study will use faces of individuals known to the patient.

There are three experiments that will be conducted in the study;

  1. Experiment 1 will attempt to determine the effects of familiarity of the photographed face on brain activity patterns. Patients will view familiar faces, the faces of close friends and relatives, and the faces of famous people.
  2. Experiment 2 will look at how maternal attachment affects the response to visual stimuli. Mothers will view pictures of their first born child, as well as those of familiar children to whom they are not related, unfamiliar children, and unfamiliar adults.
  3. Experiment 3 will explore the effects of interpersonal attachment and loss on response to visual stimuli. In this experiment, bereaved spouses will view pictures of their deceased spouse, those of living family members, and those of unfamiliar people.
Read the detailed description

This functional magnetic resonance imaging protocol uses a face recognition activation task to ascertain how brain activation patterns differ depending on the subject's familiarity with, and emotional attachment to, the person depicted in the visual stimulus. In a series of studies, subjects will view unfamiliar and familiar (including personally familiar and famous) faces; mothers will view pictures of their own child and those of familiar and unfamiliar children; and bereaved and non-bereaved spouses will view pictures of their spouse, other family members, and unfamiliar people. The use of emotionally significant faces as activation stimuli may help to elucidate the neural circuitry underlying interpersonal attachment and psychological responses to loss.

Questions about this trial

What is this clinical trial studying?

An observational study of Bereavement and Healthy, run by National Institute of Mental Health (NIMH) 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 6 inclusion and 3 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.

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 NCT00001913, 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.
