Cognitive Inhibition, Psychosocial Interactions and Suicide Attempt in Elderly

Not Applicable

• Conditions: Suicide
• Interventions: Behavioral: eye tracking; Behavioral: neuropsychological assessement; Behavioral: psychiatric assessment; Behavioral: sociological interview

• Registration Number: NCT02858427
• Lead Sponsor: Centre Hospitalier Universitaire de Besancon

Brief Summary

The study aims to determine the correlation between the cognitive inhibition impairment and the history of suicide attempt in elderly depressed patients.

Detailed Description

2 groups of patients will be studied: in the first group, depressed patients with a history of suicide attempt will be included whereas in the second group, depressed patients without a history of suicide attempt will be included.

For each group, the cognitive inhibition will be assessed trough an eye tracker task (antisaccade).

Both groups will also be compared on their neuropsychological characteristics and the quality of social interactions of participants.
