Scientists in China have discovered that sound stimulation at 40 Hertz (Hz) can help clear amyloid levels in aged monkeys. This finding shows promise for developing a new, non-invasivetherapy for Alzheimer’s disease. Researchers from the Kunming Institute of Zoology tested this method on nine elderly rhesus macaques that naturally develop brain changes similar to those seen in humans with Alzheimer’s.
During the study, the monkeys received daily one-hour sessions of 40-Hz sound stimulation for seven days. After this treatment, levels of specific proteins related to amyloid, named A?42 and A?40, increased significantly in their cerebrospinal fluid (CSF). The effects lasted for over five weeks, which is longer than in previous studies with mice.
This research supports using 40-Hz sound therapy as a possible alternative to existing Alzheimer’s treatments, which can have serious side effects like swelling in the brain. The results suggest that this sound stimulation could be a safer and less costly option for managing Alzheimer’s disease.
The study highlights the importance of using aged monkeys in research to test new therapies before they are considered for human use.
