Virtual reality-based prospective memory training program for people with acquired brain injury.

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Cognitive Psychology

Background:

• Acquired brain injuries (ABI) frequently cause cognitive impairments, notably prospective memory (PM) deficits.
• PM failure significantly hinders community reintegration for individuals with ABI.
• Existing treatment programs for PM are scarce, despite its importance.

Purpose of the Study:

• To develop and evaluate a novel 12-session virtual reality (VR)-based cognitive rehabilitation program for prospective memory (PM) deficits in ABI patients.
• To assess the effectiveness of VR-based PM training on cognitive functions and real-world outcomes.

Main Methods:

• A pretest-posttest control experimental study involving 37 ABI subjects.
• Participants underwent a 12-session VR-based cognitive rehabilitation program utilizing everyday PM activities.
• Outcomes measured included VR-based and real-life PM performance, frontal lobe functions, and semantic fluency.

Main Results:

• Significant improvements were observed in both VR-based and real-life PM measures post-intervention.
• Cognitive attributes, including frontal lobe functions and semantic fluency, also showed significant positive changes.
• The VR-based training program was well-accepted by ABI patients, indicating potential for engagement.

Conclusions:

• VR-based cognitive rehabilitation is a promising and potentially cost-effective approach for addressing PM deficits in ABI.
• This novel VRPM training demonstrates effectiveness in improving prospective memory and related cognitive functions.
• Further large-scale studies are warranted to confirm the efficacy and generalizability of VR-based prospective memory training.
