The Effectiveness of VR-Based Cognitive Training Program for Mild Cognitive Impairment: A Pilot Study.

Area of Science:

• Neuroscience
• Gerontology
• Rehabilitation Medicine

Background:

• Mild cognitive impairment (MCI) affects memory and cognitive functions.
• Emerging interventions for MCI include virtual reality (VR)-based cognitive training.
• Feasibility of VR for MCI requires evaluation.

Purpose of the Study:

• To assess the feasibility of a VR-based cognitive training program for patients with mild cognitive impairment (MCI).

Main Methods:

• Thirty-two patients with MCI underwent a 12-week VR training program (twice weekly, 50-minute sessions).
• Assessments included neuropsychological tests, mood/quality of life questionnaires, and functional neuroimaging.
• Caregivers reported on daily living activities and neurobehavioral symptoms.

Main Results:

• Twenty-eight patients completed the study; significant improvements were noted in total composite and memory scores.
• Functional neuroimaging revealed increased connectivity in the hippocampus, parahippocampal gyrus, and amygdala.
• No significant changes were observed in depression, anxiety, dizziness, or daily living activities.

Conclusions:

• VR-based cognitive training appears feasible for MCI patients.
• Improvements in cognitive scores and brain connectivity suggest potential therapeutic benefits.
• Further research with larger samples and control groups is recommended.
