Has anyone had experience using ICES for gamma wave entrainment, specifically to effect alz/dementia or parkinsons. From studies I have read using light and sound sensory stimulation this type entrainment may be very helpful. https://picower.mit.edu/innovations-inventions/genus. Also to my understanding NIR stimulation of the brain and default mode network via devices like vielight can also induce entrainment with positive effect. I was thinking about using a device such as M1 to reach areas of the brain to cause a similar effect of entrainment leading to reducing alz/dementia symptoms. My parent has dementia symptoms and I currently use photobiomodulaton (https://www.wellred.com.au/) devices to help, am experimenting with DIY sensory stimulation with light and sound but this mode is not very tolerable to them so had the thought of using ices. Any thoughts comments or experiences appreciated, thanks.
