Can Flashing Lights Stall Alzheimer's?

Researchers are exploring whether flashing lights and sounds, pulsing at 40 hertz, can help combat Alzheimer’s disease by boosting brain activity. Early studies, like those led by Coulter BME's Annabelle Singer, show promising results in both mice and human trials, suggesting that this stimulation can reduce cognitive decline without the serious side effects associated with current Alzheimer’s drugs. But many researchers urge caution, arguing that it’s too early to market these experimental devices, as more evidence is needed to confirm their long-term effectiveness and safety.
