The World's Attention! Gamma Waves Improve Dementia


The increase in the number of dementia patients is linked to the aging of the population, which has become a social problem not only in Japan but also in other developed countries around the wold. In recent years, however, a new therapy has been discovered for the treatment of dementia, for which only coping therapies had been available, and the discovery has been published in an international academic journal.


<The World's Attention! Gamma Waves Improve Dementia>

In an experiment conducted by a research team from the Massachusetts Institute of Technology in the U.S., it was found that listening to 40Hz periodic modulated sound (40 tones per second) generates gamma waves in the brain (auditory cortex and hippocampus, which is said to be the control tower of memory), and that accumulated amyloid beta protein, which causes Alzheimer's disease, is reduced. The results showed that the accumulated amyloid-β protein, which causes Alzheimer's disease, was reduced and cognitive impairment was improved. In addition, the number of glial cells that remove debris in the brain increased, and vascular changes (neogenesis) improved. Memory impairment of objects and places was also improved.


It is widely known that certain frequencies affect the human brain, and characteristic frequencies of brain waves and mental functions include alpha waves (8-13Hz) relaxation, beta waves (14-30Hz) mild excitement, theta waves (4-7Hz) deep meditation, delta waves (1-3Hz) deep sleep, and gamma waves ( The effects and benefits of sound on the brain, such as the processing of sensory information (cognition), are being elucidated day by day through the efforts of researchers.


LEQEMBI (lecanemab), which has received full approval from the U.S. FDA as a treatment for Alzheimer's disease, is an epoch-making new drug that eliminates the disease-causing substance (amyloid beta protein) rather than providing symptomatic treatment. It has been approved in Japan and is expected to bring epoch-making results to the Japanese medical community in the near future!


Incidentally, the effects of these gamma waves are more effective for people in the early stages of dementia and have preventive effects for those who have not yet developed dementia, so it is recommended that they be actively incorporated into daily life.


The year 2023 brought a series of exciting news for people suffering from dementia, such as the national government's promotion of dementia measures. Let's practice & utilize such useful information so that it will not be in vain!
