Listening to This Sound Could Help Treat Alzheimer’s Disease
Summary
A new study suggests that listening to sounds at a specific frequency might help treat Alzheimer's disease. Researchers discovered that 40 Hz sound waves helped remove harmful proteins from the brains of aged monkeys, which could open new ways to manage Alzheimer's in humans.Key Facts
- Researchers from the Kunming Institute of Zoology studied the effects of 40 Hz sound waves on elderly rhesus monkeys.
- The sound exposure helped clear β-amyloid proteins from the brain, linked to Alzheimer's.
- After one week of sound treatment, levels of key proteins increased significantly in the monkeys' cerebrospinal fluid.
- The increased protein levels lasted for up to five weeks after the sound treatment stopped.
- Approximately 139 million people worldwide may have dementia by 2050.
- Gamma waves, like the 40 Hz frequency used, have been associated with brain health in previous studies.
- A 2016 MIT study showed similar positive results using 40 Hz light and sound on mice with Alzheimer's symptoms.
