Scientists from mit have been able to remove from the mice brain of harmful proteins associated with Alzheimer’s disease using only light and sound, reports Science Alert.
The researchers found that the strobe lights and the faint hum can be used to generate brain waves that can remove harmful proteins and to improve cognitive ability in mice that suffer from a condition similar to Alzheimer’s disease.
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.
It is noted that the technique was not tested in humans, brain waves in rodents behave differently, so the researchers are not speaking about a definite breakthrough. But in the case of continued success, scientists will be able to offer a non-pharmacological method of treating a common form of dementia.
