Illumination formula forming and optimizing method for detecting and preventing cognitive impairment and implementation device

Abstract

The invention provides an illumination formula forming and optimizing method for detecting and preventing cognitive impairment and an implementation device. The method comprises the following steps of performing a first fMRI experiment on all tested objects to obtain first functional magnetic resonance imaging data; randomly dividing the tested objects into a test group and a contrast group, and respectively carrying out illumination stimulation by using a to-be-optimized illumination formula and a reference illumination formula; performing a second fMRI experiment on all the tested objects to obtain second functional magnetic resonance imaging data; obtaining stimulation results of the whole brains of the two groups of tested objects and influence results on brain interval function connectivity; mining a brain network activity specificity index related to the to-be-optimized illumination formula, and establishing the incidence relation between the specificity index and a clinical diagnosis index; and determining an improvement direction of the illumination formula and presetting an improvement numerical value of the illumination parameter, and finally determining an illumination strategy for preventing cognitive impairment and improving cognitive recognition memory ability and an optimized illumination formula.

Description

technical field [0001] The invention proposes an illumination formula formation and optimization method and a realization device for detection and prevention of cognitive impairment, belonging to the technical field of medical detection. Background technique [0002] Light is necessary for vision, is the main sensory channel for human beings to perceive external information, and has a crucial impact on human physiological functions. In general, abnormal light conditions can lead to problems in areas such as circadian rhythm, sleep, mood and cognitive function. Given the sensitivity of the human brain to light, more and more research attempts to use light fields as a tool to regulate the brain in an attempt to improve mental illness and cognitive abilities. Differences in the visual and nonvisual effects of light in the brain are well known. Specifically, light affects non-visual systems through intrinsically photosensitive retinal ganglion cells (IPRGCs) projecting to the ...
