Dementia risk screening system and device based on VR eye movement tracking and medium

Abstract

The invention provides a dementia risk screening system based on VR eye movement tracking, and the system comprises a display module which is used for displaying different types of test tasks through VR equipment; the tracking module is used for tracking an eye movement track within a preset time; the first determination module is used for determining a concern of the corresponding test task; the first extraction module is used for extracting a first eye movement feature corresponding to the test task; the screening module is used for acquiring a prediction category output by the dementia screening model; the second determination module is used for determining a target test task corresponding to the prediction category and determining a corresponding target eye movement track when the prediction category is normal or mild; the second extraction module is used for extracting a second eye movement feature of the target eye movement track; and the risk assessment module is used for determining the transformation risk probability according to the risk transformation assessment model, and the system not only can perform dementia screening, but also can predict the probability of future risk transformation.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a dementia risk screening system, device and medium based on VR eye tracking. Background technique [0002] Mild cognitive impairment (MCI), refers to memory and cognitive impairment that is more severe than normal aging, but does not significantly impair daily functioning. A large number of studies have shown that not all MCI patients will develop Alzheimer's disease (AD) in the future, and about 50% of MCI will develop dementia within 3 years. There is an urgent need for reliable systems to predict future clinical trends in MCI patients, and translate to AD risk. Existing strategies to accurately diagnose early dementia are limited by the high cost and invasiveness of surgery. [0003] Dementia is often diagnosed using neuropsychological tests such as the Mini Mental Status Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). Although these tradi...

Problems solved by technology

[0005] Based on this, in view of the above-mentioned problems that the current dementia prediction results are not accurate enough and cannot predict future transformation risks, this application proposes a dementia risk screening system, computer equipment and storage media based on VR eye movement tracking. Efficiently and accurately predict dementia and enable risk prediction for people who have not yet developed dementia
