Memory decline is a prevalent aspect of aging but may also be the
first sign of cognitive pathology. Virtual reality (VR) using immersion and
interaction may provide new approaches to the treatment of memory deficits in
elderly individuals. OBJECTIVE: The authors implemented a VR training
intervention to try to lessen cognitive decline and improve memory functions.
METHODS: The authors randomly assigned 36 elderly residents of a rest care
facility (median age 80 years) who were impaired on the Verbal Story Recall Test
either to the experimental group (EG) or the control group (CG). The EG underwent
6 months of VR memory training (VRMT) that involved auditory stimulation and VR
experiences in path finding. The initial training phase lasted 3 months (3
auditory and 3 VR sessions every 2 weeks), and there was a booster training phase
during the following 3 months (1 auditory and 1 VR session per week). The CG
underwent equivalent face-to-face training sessions using music therapy. Both
groups participated in social and creative and assisted-mobility activities.
Neuropsychological and functional evaluations were performed at baseline, after
the initial training phase, and after the booster training phase. RESULTS: The EG
showed significant improvements in memory tests, especially in long-term recall
with an effect size of 0.7 and in several other aspects of cognition. In
contrast, the CG showed progressive decline. CONCLUSIONS: The authors suggest
that VRMT may improve memory function in elderly adults by enhancing focused
attention.
