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

Официальное название

Use of Virtual Reality as a Cognitive Remediation Tool in the Depressed Elderly Subject

Обзор

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.

Подробное описание

Every patient diagnosed with depression receives psychotropic treatment comprising one or more antidepressants, possibly combined with one or more thymoregulators (e.g. bipolar patients), one or more anxiolytics and/or a hypnotic. The elderly depressive patient is also treated with supportive psychotherapy and/or group therapy at the day hospital. The trial proposes an additional tool, virtual reality, aimed at improving the cognitive abilities, particularly executive abilities, of the elderly depressive subject, thereby helping to maintain his or her functional abilities, i.e. his or her ability to stay as autonomous as possible at home and maintain a good quality of life. In fact, cognitive disorders associated with depression do not respond to antidepressant medication, if at all. It therefore seems important to optimize the treatment of depression in the elderly subject by adding a cognitive target. The investigators's project is to offer patients the opportunity to live in a virtual kitchen, where they can carry out everyday tasks. The scenario for the VR sessions has been designed in collaboration with, the principal investigator at CHU and his team, and the members of B COM and HDG involved in the study. Particular attention is paid to the fact that this scenario is intended for an elderly patient population, so as to prevent as far as possible the occurrence of cybermalaise The patient will be asked to arrange food shopping appropriately, differentiating between perishable and non-perishable foodstuffs and non-food items, or to prepare cooking recipes. Virtual reality has the advantage of being able to offer ecological, configurable activities, targeting precise tasks that call on executive functions such as initiative, anticipation and planning, mental flexibility and inhibition. Patients will undergo 12 VR sessions at a rate of 2 sessions per week for 6 weeks.
