Red and near infrared lights – can they help degenerative neurological diseases?
Alzheimer’s Disease is one of the significant causes of people developing dementia. Mostly occuring in older people, it can appear in those of younger ages. The research has been focused on drugs to disrupt the amyloid proteins found in the brain of people with Alzheimer’s, but despite billions of dollars spent on this research, it has proved a costly failure. Red and near infrared lights have much to offer.
I’ve been reading articles suggesting that Alzheimer’s disease is linked with a disruption of brain wave patterns, especially the gamma waves which are predominant in the brain when we are concentrating and focussed.
One group increased gamma wave activity in Alzheimer’s mice by pulsing light. In this research, it wasn’t the light that was of interest to the researchers, it was the pulse rate. They used 40Hz, in the gamma brainwave frequency range.
Here is a great report about that experiment and it’s implications.
…stimulating neurons to produce gamma waves at a frequency of 40 Hz reduces the occurrence and severity of several Alzheimer’s-associated symptoms in a mouse model of the disease.
It seems that pulsing the light does more than enable red light to penetrate more deeply into the brain. Pulsing at 40Hz seems to stimulate the brain’s immune and clean-up cells, the microglia to get cracking with brush and pan.
I have visions of microglial cells dancing to the 40 Hz rhythm as they clear up brain rubbish, including the proteins that accumulate in Alzheimer’s – amyloid and tau.
In 40Hz pulsed red light, the brain gets the benefits of the red light action inside the cells, and the benefits of brain-protection activities stimulated by brainwaves responding at 40Hz.
Fascinating stuff, isn’t it.
Meanwhile, if you are feeling worried that your Eliza or Cossack doesn’t pulse, don’t fret. The daily light dose is doing its work. More.
