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.

Study Arms (3)
Young adults
ACTIVE COMPARATORParticipants aged between 18 and 40 years old.
Healthy old adults
ACTIVE COMPARATORParticipants aged between 65 and 95 years old.
Patients with Alzheimer's Disease
EXPERIMENTALParticipants aged between 65 and 95 years old with a diagnosis of Alzheimer's Disease.
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.
