Use of Virtual Reality as a Tool for Cognitive Remediation in Elderly Depressed Patients

Depression, the most common mental disorder affecting the elderly, represents a major public health issue. This pathology leads to a loss of activity and autonomy in the elderly. It impairs executive skills, enabling a person to take initiatives, perform goal-oriented actions and adapt to new situations. Impaired executive functions greatly increase the risk of loss of autonomy and institutionalization, as well as the burden on caregivers. Antidepressant treatments have little or no effect on cognitive disorders. It therefore appears necessary to offer these patients specific treatment of these cognitive symptoms. The investigators are interested in cognitive remediation based on virtual reality (VR) for its ecological and modular characteristics, the innovative aspect of this technique, the appeal of virtual experiences, and their easy access to the general public. The main objective of this study is to demonstrate the acceptability of the VR technique in a population of subjects aged 70 and over, suffering from cognitive disorders and associated depression.

In this study the investigators support the use of VR as a tool for cognitive remediation and ecological staging of their interactions with caregivers in the face of executive disorders found in patients suffering from depression. By improving their cognitive skills, VR brings greater autonomy and improved quality of life for patients and their caregivers. The investigators therefore plan to use a virtual environment to create scenarios that reproduce real-life situations, which appear to be more relevant than conventional cognitive remediation exercises.

The investigators chose acceptability as the main criterion for this technique, as the elderly population is identified as a sensitive population in the opinion issued by ANSES in June 2021. What's more, this population is often excluded from the new digital technologies; it therefore seems interesting to look at the acceptability of virtual reality by this elderly population.
