Delivering more oxygen into brain
Needs verification of clinical effectiveness

A healthy brain has an internal rhythm of 40-Hertz. But Alzheimer’s brains have lower frequency pattern compared to healthy brains of the same age. If so, can brain stimulation with 40-Hz external sound vibration restore cognitive function in Alzheimer’s patients?

In a pilot study in 2016, researchers from the University of Toronto and the Baycrest Health Sciences in Toronto found that Alzheimer’s patients showed temporary improvement in cognition including memory and alertness after sitting for 30-minute sessions in a vibro-acoustic chair which uses rumbling sounds at 40-Hz.

Researchers in South Korea are attempting sound-stimulation study, similar to that in Canada. Recently, AriBio, an integrated biotech company in the clinical stage aimed at developing treatments for intractable diseases including Alzheimer’s dementia, announced that the acoustic vibration device called ‘Vibroacoustics Device’ was designated as the ‘Approval Helper for New Medical Devices" by the Ministry of Food and Drug Safety.

The ‘Approval Helper for New Medical Devices’ is a system that was institutionalized by the government in order to support rapid commercialization of new and rare medical devices by shortening the licensing period and reducing costs through multi-department cooperation.

AriBio is developing this device in conjunction with Evosonics, a healthcare company that researches into acoustic vibration technology.

The device is thought to improve cognitive function and alleviate other symptoms of dementia by increasing the oxygen concentration of hemoglobin in the brain through acoustic vibration at 40~100-Hz.

Since treatment options for dementia are very limited so far, this device can be another option for non-pharmacological treatment of dementia. But the process of verifying the clinical effect seems to be essential before applying it to clinical practice.
