Can light be used to slow the progression of neurodegenerative diseases (Parkinson’s, Alzheimer’s, etc.)? This is an avenue currently being explored by REGEnLIFE, among others, and one that is already showing encouraging results.
A technique known as photobiomodulation is currently being trialled for the treatment of Parkinson’s and Alzheimer’s diseases. Initial results are encouraging and suggest that this approach uses near-infrared light to stimulate neurons in order to protect them.

Whilst research into Parkinson’s disease is advancing rapidly, thanks to new treatments that improve patients’ quality of life, these treatments merely address the symptoms without actually slowing down the neurodegeneration that causes the disease. “Finding a treatment that truly protects neurons is the holy grail of neuroscience,” says Professor John Mitrofanis, a specialist in neurodegenerative diseases. .
