About this study

Official title: Attentional Capture by Emotional Information in Alzheimer's Disease : an fMRI Study

The main purpose of this study is to investigate the existence of emotional attention impairments in Alzheimer's Disease, in correlation with amygdala and attention networks alterations. To this end, functional and structural neuroimaging will be used. A face expression recognition task, along with eyetracking, will be used to assess emotional attention impairments.

Being tested
Facial expression recognition task
Keywords
attention, emotion, eye movements, amygdala
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Facial expression recognition taskBehavioural

    We will present emotional expressions to participants. Their task will be to determine which emotion is expressed by each face. Participants' eye movements and brain activity will be recorded while they explore the face.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Classic recognition score

    Facial expression recognition score (%)

    Measured: 1 hour

  2. Classic fixation time faces

    Fixation time on eyes as measured with eyetracking (ms)

    Measured: 1 hour

  3. Fixation time scenes

    Fixation time on emotional scenes outside of MRI

    Measured: 30 mn

  4. Classic fMRI activity

    fMRI activity in amygdala and emotional attention networks during face exploration and resting-state

    Measured: 2 hours

Secondary outcomes (3)
  1. Alternative recognition score

    Facial expression recognition score (%) during an alternative task designed to encourage focus on the eyes

    Measured: 1 hour

  2. Alternative fixation time faces

    Fixation time on eyes as measured with eyetracking (ms) during this alternative task.

    Measured: 1 hour

  3. Alternative fMRI activity

    fMRI activity in amygdala and emotional attention networks during this alternative task

    Measured: 2 hours

Questions about this trial

What is this clinical trial studying?

A study testing Facial expression recognition task in people with Alzheimer Disease, run by University Hospital, Grenoble at 1 site in France.

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 18 inclusion and 16 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 18 Jan 2022. 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 France. 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?

Classic recognition score (time frame: 1 hour). The study lists 4 primary outcomes in all. 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 18 Jan 2022.
