Scientists at mit have managed, with the help of light and sound to clear the brain of mice from the harmful proteins that trigger the human development of Alzheimer’s disease — an incurable form of dementia, ending in death. This publication reports Science Alert.

Researchers have shown that strobe lights and the faint hum can be used to generate brain waves in the gamma — rhythm, which deteriorates in a neurodegenerative disease. In the experiment, the new method allowed to reduce the number of pathogenic protein accumulations and improve cognitive function in mice suffering from a condition similar to Alzheimer’s in humans.

Visual stimulation was manifested in the flashing of light 40 times per second, and hearing — the impact of the sound with the same frequency, i.e. 40 Hz. There have been changes in the hippocampus and prefrontal cortex of rodents and the reduction of plaques formed by Tau proteins, and amyloid. It is believed that these compounds play a key role in the neurodegenerative process.

At the moment, from Alzheimer’s are suffering of 26 million people, and it is expected that by 2050 that number will become four times more. Gradually patients is a loss of long term memory, disturbances of speech and cognitive functions, in the end, patients lose the ability to care for themselves.
