Subject: Studies: Myelin Damage from Radiofrequency Radiation 

glioma is a type of malignant tumor that starts in the brain or spine. It is called a glioma because it arises from glial cells.

Myelin is the protective layer around nerve cells, analogous to the plastic coating insulating electrical wires.
Myelin is an outgrowth of a type of glial cell
Damage to myelin causes neurological problems, such as numbness, paraethesia (prickling and burning sensations), headaches, memory and concentration impairment, irritability, anxiety, and confusion (in children) These are also symptoms in electrohypersensitivity, or EHS.
Demyelination also occurs in diseases like multiple sclerosis.
In May 2016, the US government’s National Toxicology Program’s 2-year study showed that 3% of rats that were exposed to cell phone radiation developed gliomas, whereas rats that were not exposed did NOT develop gliomas. Results were statistically significant
The full study results were just released earlier in February 2018.  There are 2 draft technical reports (1 for rats, 1 for mice), which can be found here
Here’s a related post by Dr. Joel Moskowitz, UC Berkeley, Effects of Exposure to Electromagnetic Fields: 833 studies
Below are 3 papers regarding myelin damage and wireless radiation:
found that RF-EMF exposure led to myelin sheath damage and hyperactivity-like behaviour in mice exposed to 835 MHz RF-EMF at a specific absorption rate (SAR) of 4.0 W/kg for 5 hours/day during 12 weeks.  Demyelination was induced in cortical neurons following prolonged RF-EMF exposure and suggests a potential cause of neurological or neurobehavioural disorders.

considers the evidence for an association between myelin integrity and exposure to low-intensity radiofrequency electromagnetic fields (RF-EMFs)
Overall, evidence from in vivo and in vitro and epidemiological studies suggests an association between RF-EMF exposure and either myelin deterioration or a direct impact on neuronal conduction, which may account for many electrohypersensitivity symptoms. The most vulnerable are likely to be those in utero through to at least mid-teen years, as well as ill and elderly individuals.

This is a case study of a Colorado woman who experienced a return of her demyelination symptoms (seizures, vertigo, headaches, sleeping problems) following exposure to her neighbor’s (Xfinity) Home Wi-Fi Modem with Public Hotspot in August 2014.  

After her neighbor replaced the modem with one without the hotspot feature, the  seizures stopped immediately, and the other symptoms faded gradually, after which she was fine and  
again could sleep well. Later, when another neighbor obtained the same modem with activated hotspot, her s ymptoms returned.


A possible association between electrohypersensitivity, myelin integrity and exposure to low-intensity radiofrequency electromagnetic fields (RF-EMF) has recently been proposed. Since the West Nile virus attacks both the nerve cells and the glial ones, one explanation to the above observed case effects is that the initial virus attack and the wireless modem’s RF-EMF affect the nervous system through the very same, or similar, avenues, and maybe both via the oligodendrocytes

NY Times Best Selling Author Elana Amsterdam from Colorado shares a similar story – how high levels of wireless EMF in her “smart” home triggered a recurrence of her Multiple Sclerosis symptoms in 2014  She was diagnosed with MS in 2006 and was able to keep it under control with a healthy Paleo diet.  After moving into a her new “smart” home in 2014, her MS returned, and she ended up in the hospital, numb from the neck down .  She wasn’t recovering despite her best efforts.  In 2016, after doing research on the health effects of wireless radiation and making the connection that wireless radiation was causing her symptoms, she removed all wireless technology from her home and is now on the road to recovery.
(if you are a Comcast/Xfinity customer, you probably have a modem with a public hotspot feature since this equipment became their standard issue in 2014.  Xfinity’s home wireless gateway modems have 2 lines of Wi-Fi – one for your household use, and another for public hotspot use – use of one does not affect speeds/capacity of the other, and there are no security issues since they are separate lines.  However, you are paying for the power to supply wi-fi to the public hotspot range of 100m around your modem and you are exposing yourself to much higher wireless radiation levels with a public hotspot on your router,   Here’s more info. about the home hotspot feature and a video that explains it, and a link to disable the public hotspot feature on your Xfinity modem.  In April 2017, xfinity launched its nationwide mobile service which depends on the public wi-fi hot spots in these modems.  You will know if you are within range of an Xfinity hot spot if your smartphone/ipad/laptop shows that there is “xfinitywifi” available in the list of wireless networks. Disabling the Wi-Fi hot spot requires a separate procedure from disabling the Wi-Fi for your household use on the modem.  To turn off the Wi-Fi for your household use, such as when you go to sleep at night, type in in your browser window.  login (user: admin), select connection, select wi-fi, select edit, select disable (to turn back on, do the same thing, but in the last step, select enable) )
