Immersive Technologies for Cognitive Rehabilitation in Dementia and Mild Cognitive Impairment: A Systematic Review
ABSTRACT
Background:
Cognitive rehabilitation is essential in the management of mild cognitive impairment (MCI) and dementia. Immersive technologies such as virtual reality (VR), augmented reality (AR), and Cave Automatic Virtual Environment (CAVE) systems have gained attention as novel tools to enhance rehabilitation
Objective:
This systematic review synthesizes current evidence on the usability, cognitive benefits, and implementation challenges of immersive technologies for cognitive rehabilitation in MCI and dementia.
Methods:
A systematic search of Scopus and Web of Science was conducted (January 2020 – May 2025). Eligible studies included VR, AR, or CAVE interventions for individuals with MCI, dementia, stroke, or traumatic brain injury. Outcomes assessed included usability, acceptability, cognitive performance, and rehabilitative effectiveness.
Results:
Thirty-one studies met the inclusion criteria. Immersive VR interventions improved memory, attention, and executive function in MCI and dementia patients, while AR tools enhanced daily living support. CAVE systems provided spatial navigation and full-body engagement. Barriers included cybersickness, device limitations, high costs, and caregiver burden.
Conclusions:
Immersive technologies offer promising, engaging tools for cognitive rehabilitation. Standardization of protocols and outcome measures is required to strengthen evidence and facilitate clinical translation. Clinical Trial: Not applicable (systematic review).
