Background:

Aging is associated with molecular damage from free radicals, leading to neural dysfunction and memory impairment.
D-galactose is commonly used to induce aging models in rats for research purposes.

Purpose of the Study:

To investigate the potential of bioceramic material and colored light to mitigate neurodegenerative symptoms and memory deficits in aging rats.
To assess the effects of different color light spectrums on cognitive functions in D-galactose-induced aging rats.

Main Methods:

D-galactose-induced aging rat model.
Assessment of cognitive functions using the Morris water maze, novel object recognition test, and open field test.
Application of bioceramic material combined with various colored light spectrums.

Main Results:

Bioceramic material with different light wavelengths significantly improved activity, recognition, and memory in aging rats.
Notable enhancements were observed in the open field and novel object recognition tests.
A trend toward improvement was noted in the Morris water maze, suggesting positive effects on spatial memory.

Conclusions:

Bioceramic materials, potentially through antioxidant properties and microcirculation enhancement, positively influence cognitive function in aging rats.
Colored light stimulation may impact physiological and psychological pathways, contributing to cognitive benefits.
This study underscores the therapeutic potential of combining bioceramic materials and color light therapy for age-related cognitive decline.
