KAIST researchers developed OLED-based Alzheimer's treatment

Researchers from Korea's KAIST institute, in collaboration with colleagues from the have developed OLED-based photo-stimulation treatment for Alzheimer's disease, showing that red OLED light could improve the brain's memory function.

The researchers say that using OLEDs rather than LED, has several benefits - better brightness balance, less heat generation risk, and less stimulation variation due to animal movement (they tested this on mice).

The study compares white, red, green, and blue OLED light under identical conditions (40Hz frequency, brightness, exposure time) and it was found that red light produced the most significant improvement in memory function. The say that in early-stage Alzheimer's even just two days of stimulation led to improvements in both pathology and memory.

This study is significant in that it is the first to demonstrate that cognitive function can be improved using only light, without medication, and that Alzheimer's pathological indicators can be modulated by combining color, frequency, and duration.
