In the elderly, we can see a post-traumatic syndrome associated with an event that occurred before old age that had not previously manifested or not fully manifested.

This little-known pathology and notable psychiatric co-morbidities (depression, anxiety) can take in elderly subjects different masks that interfere with diagnosis and treatment.

The data in the literature suggest that this Post-Traumatic Stress Disorder with Delayed Expression (TSPT-R) may be related to a deficiency of the executive functions of inhibition, and more particularly a deficit of mental memory inhibition and therefore the removal of unwanted memories.
