Abstract

Objective: Patients diagnosed with amnestic syndrome are limited in their daily living activities and a full recovery is rare. Neurofeedback as well as interventions in a virtual reality are applied in this case study and the recovery of memory deficits is analyzed.

Design: 15 days of intervention were carried out applying Neurofeedback followed by a 20 minutes virtual reality intervention using the software beat saber to gain insight into the applicability of Neurofeedback and virtual reality in increasing memory functions and overall attention.

Methods: A 36-years-old female subject, Patient S.S., was treated with EEG-biofeedback using a 19-Channel z-score protocol for a period of 15 sessions. Furthermore, a 20 minutes task was given to patient S.S. in virtual reality. A visual field attention test, an app-based digit span test and the Romberg stance test were carried out and recorded prior and after the interventions.

Results: The visual field attention test after the intervention indicate significant changes in the reaction time in the central and peripheral visual fields compared to the testing prior to the intervention. Improvements are also recorded in the app-based TapBrain Test. No decisive changes are detected in the Romberg stance test.

Improvements in the z-scores in the occipital lobe are found based on the Neurofeedback intervention. Moreover, Beat Saber tasks in virtual reality improved throughout the intervention.

Conclusion: A multimodal approach in applying Neurofeedback and using cognitive perceptual tasks in virtual reality have a positive impact on patient S.S. visual field attention, procedural memory as well as her working memory.
