Russian doctors will treat dementia with light

Scientists at Saratov National Research State University named after N.G. Chernyshevsky (SSU) are developing a new direction in biophotonics — lymphatonics. They found that the meningeal lymphatic vessels (MLS) located in the meninges of the brain can be effectively stimulated with light, improving the elimination of toxins and slowing the development of diseases.

"For the first time in the world, we have shown that meningeal lymph vessels are ideal targets for therapeutic exposure to light. They are located in the membranes of the brain directly on its surface, and therefore light, even with loss of energy when passing through the skull and scalp, has a stimulating effect on the functions of the MLS," said Oksana Semyachkina-Glushkovskaya, head of the Department of Human and Animal Physiology and deputy head of the SSU Scientific Medical Center.

According to her, the first medical device for light brain stimulation, AS—SGMO, will appear in Russia in 2026, and it is currently undergoing clinical trials. It is a non-invasive device that acts on the lymphatic vessels through the scalp, improving drainage function. In the coming years, similar technologies are planned to be implemented in foreign partner scientific centers of SSU in China, India and Iran.
