A new study finds that 40Hz light and sound therapy helps maintain myelin, a crucial brain structure, in Alzheimer's patients. This therapy, which protects neurons and supports brain function, could offer new treatment avenues for neurodegenerative diseases. Researchers discovered that this stimulation enhances neural connections and reduces harmful inflammation. The therapy also shows potential for treating other conditions involving myelin loss, such as multiple sclerosis.

Researchers uncover how specific brain cells and circuits become vulnerable in Alzheimer's disease and identify factors that may promote resilience to cognitive decline. Analyzing gene expression in over 1.3 million cells across multiple brain regions, the study highlights the role of Reelin in neuron protection and choline metabolism in astrocytes for cognitive resilience. These findings pave the way for potential therapeutic targets to sustain cognition and memory amid Alzheimer’s pathology.
