MedicalResearch.com: What are the main findings of the study?
Answer: We examined 75 healthy older people and 134 patients with mild cognitive impairment. Our aim was to collect neuropsychological, neurophysiological, neuroimaging and behavioural data by means of a virtual reality serious game, in order to model the profile of the patients who will progress to dementia within the next 2-4 years. We found that the prediction based on the performance at the virtual reality based computerized assessment instrument is comparable to that of more established and widely accepted biomarkers, such as ERP and MRI. This can be explained by the cognitive fidelity and richness of behavioural data collected with virtual reality based measures, which directly reflect neurocognitive processes affected at a very early stage.
