NCT03971994

Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • Classic recognition score

    Facial expression recognition score (%)

    1 hour

    Fixation time on emotional scenes outside of MRI

    30 mn

  • Classic fMRI activity

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

Study Arms (3)

Young adults

ACTIVE COMPARATOR

Participants aged between 18 and 40 years old.

Behavioral: Facial expression recognition task

Healthy old adults

ACTIVE COMPARATOR

Participants aged between 65 and 95 years old.

Behavioral: Facial expression recognition task

Patients with Alzheimer's Disease

EXPERIMENTAL

Participants aged between 65 and 95 years old with a diagnosis of Alzheimer's Disease.

Behavioral: Facial expression recognition task

Interventions

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.
