Light and Sound Therapy devices

Does anyone have any opinions or experiences using the light/sound therapy devices below in terms of improving Alzheimer's symptoms?

Is there one that stands out as something to try?


MindAlive has a couple of devices like the Delight Plus that uses Audi-Visual Entrainment (AVE) stimulation, which sends 40 Hertz gamma light and sound to the brain. The Delight Pro device has both AVE and Cranio-Electro Stimulation (CES), which sends an electric current to the brain in addition to light/sound.

Is there any extra benefit with the electric current (CES) model?

I've read that the CES can be used to send an electrical signal through the default network.

The CES add-on is like a whole separate treatment, the theory of how it works is different.  

I like that it seems to be easier to use than a contact system that requires barely damp sponges or conductive gel.


Nope, I was wrong, you do still need water, conductive (or hair) gel, or saliva to make a good connection. I felt a mild tingling, but haven't tried it on its own, or for long enough to assess how well it works.

A bit about the default network from Wikipedia



The default mode network has been hypothesized to be relevant to disorders including Alzheimer's disease, autism, schizophrenia, depression, chronic pain, posttraumatic stress disorder and others.[4][34] In particular, the DMN has also been reported to show overlapping yet distinct neural activity patterns across different mental health conditions, such as when directly comparing attention deficit hyperactivity disorder and autism.[35]

People with Alzheimer's disease show a reduction in glucose (energy use) within the areas of the default mode network.[4] These reductions start off as slight decreases in mild patients and continue to large reductions in severe patients. Surprisingly, disruptions in the DMN begin even before individuals show signs of Alzheimer's disease.[4] Plots of the peptide amyloid-beta, which is thought to cause Alzheimer's disease, show the buildup of the peptide is within the DMN.[4] This prompted Randy Buckner and colleagues to propose the high metabolic rate from continuous activation of DMN causes more amyloid-beta peptide to accumulate in these DMN areas.[4] These amyloid-beta peptides disrupt the DMN and because the DMN is heavily involved in memory formation and retrieval, this disruption leads to the symptoms of Alzheimer's disease.
