EMF and the brain

Microwave Sickness

and other symptoms from the brain

How does wireless effect the brain?

Wireless technologies can effect the brain by giving it stress and by oxidative stress mechanisms.

It can damage the brain and this can give various symptoms.

  • Stress. Stress symptoms are common symptoms.

  • Sleeping problems.

  • The blood-brain barrier can be damaged.

  • Cells can die.

  • Cancer cells like glioma can develop. 

  • Behaviour and function can be effected like ADHD, autism ao.

  • Problems with concentrating

  • Speaking can be effected and language development can be slowed.

  • Mathematical thinking can be affected.

  • Nerves and myelin around the nerves can be damaged.

  • Inflammation in the brain.

  • Stress, irritability, and even aggression can be seen.

  • Microwave sickness is often shown by nerve pain in the brain.

  • Some get dizzy. 

Often just some or a few of these symptoms are present.


Functional brain MRI in patients complaining of electrohypersensitivity after long term exposure to electromagnetic fields

PubMed 2017

Gunnar Heuser Sylvia A Heuser

The study made fMRI scans on 10 people suffering from EHS (microwave sickness).

“All ten patients had abnormal functional MRI brain scans. The abnormality was often described as hyper connectivity of the anterior component of the default mode in the medial orbitofrontal area. Other abnormalities were usually found. Regular MRI studies of the brain were mostly unremarkable in these patients.”

The study highlights hyperconnectivity in the anterior component (of the default mode network) in the area medial Orbitofrontal Cortex.

The medial orbitofrontal cortex is associated with decision-making, emotional regulation, and reward processing.

Microwave Sickness

How does wireless radiation stress the brain?

You can measure on an EEG how wireless devices stress the brain.

Wi-fi stresses the brain

Brain waves

Here you can see how wi-fi stresses the brain.


Picture 1:

The first picture shows an EEG where the brain waves have been measured. The measurements are normal.

There’s no wi-fi. The wi-fi is turned off.


Picture 2:

Here you can see the brain waves measured with wi-fi (WLAN) turned on. The EEG measurement shows an abnormal level af stress on the brain.

fMRI brain scans

The brain scans show abnormality.

10 patiens with EHS symptoms were scanned and all brain scans showed abnormal results.

Scan showed connectivity and the brains were hyperconnected (can be seen on the images).

SPECT brain scans

6 firefighters working under mobile phone mast at the fire station.

The firefighters were healthy before the mobile phone cell towers were put up.

The firefighters had problems with cognition, problems finding the way when driving, headaches, disorientation, and neurological problems.

He explains how increased activity and increase in brain if it continuous can lead to a decrease of the brain (in the areas).

These data is from an MEI scan of an electrical lineman. He suffered from seizures.

Small amounts of repetitive stimulation can give seizures.

His right occipital lope is much larger and his left lope is much smaller.


Brain cancer after radiation exposure from CT examinations of children and young adults: results from the EPI-CT cohort study

6 Dec 2022

“BackgroundThe European EPI-CT study aims to quantify cancer risks from CT examinations of children and young adults. Here, we assess the risk of brain cancer.”


The observed significant dose-response relationship between CT-related radiation exposure and brain cancer in this large, multicentre study with individual dose evaluation emphasises careful justification of paediatric CTs and use of doses as low as reasonably possible.”

Associations Between Infant Screen Use, Electroencephalography Markers, and Cognitive Outcomes

JAMA Pediatr. Published online January 30, 2023

Conclusions and Relevance  

In this study, infant screen use was associated with altered cortical EEG activity before age 2 years; the identified EEG markers mediated the association between infant screen time and executive functions. Further efforts are urgently needed to distinguish the direct association of infant screen use compared with family factors that predispose early screen use on executive function impairments.

Study: Infants exposed to excessive screen time show differences in brain function beyond eight years of age

NUS Yong Loo Lin School of Medicine

Published: 31 Jan 2023

The brain of a child grows rapidly from the time of birth until early childhood. However, the part of the brain that controls executive functioning, or the prefrontal cortex, has a more protracted development. Executive functions include the ability to sustain attention, process information and regulate emotional states, all of which are essential for learning and school performance. The advantage of this slower growth in the prefrontal cortex is that the imbuing and shaping of executive function skills can happen across the school years until higher education. However, this same area of the brain responsible for executive functioning skills is also highly vulnerable to environmental influences over an extended period of time.

This study points to excessive screen time as one of the environmental influences that may interfere with executive function development. Prior research suggests that infants have trouble processing information on a two-dimensional screen.”



Study Probes Connection Between Excessive Screen Media Activity and Mental Health Problems in Youth

21 Martz 2023


“Smartphones, tablets, gaming systems, and other screen devices have become a major temptation for people of all ages, but a new study is focusing on the possible connection between excessive screen media activity and mental health problems in youth.”




Longitudinal Associations Between Use of Mobile Devices for Calming and Emotional Reactivity and Executive Functioning in Children Aged 3 to 5 Years

December 12, 2022

Conclusions and Relevance  

The findings of this study suggest that the frequent use of mobile devices for calming young children may displace their opportunities for learning emotion-regulation strategies over time; therefore, pediatric health care professionals may wish to encourage alternate calming approaches.




Giving your child a screen may hinder emotional regulation, study says. Here’s what to do instead

December 12, 2022

CNN writes:

“When you see your 3- to 5-year-old having a tough emotional moment, meaning they are screaming and crying about something, they’re getting frustrated, they might be hitting or kicking or lying on the floor. … If your go-to strategy is to distract them or get them to be quiet by using media, then this study suggests that is not helping them in the long term,” said Radesky, associate professor of behavioral sciences at the University of Michigan Medical School.

There are two problems with distracting with media: It takes away an opportunity to teach the child about how to respond to difficult emotions, and it can reinforce that big displays of their difficult emotions are effective ways to get what they want, Radesky said.

“I’m just going to show big emotions so we can stop what we’re doing, and I can escape this demand,” she said.

The study lines up with the current recommendations from the American Academy of Pediatrics, the American Academy of Child and Adolescent Psychiatry and the World Health Organization that children ages 2 to 5 should have very limited screen time, said Dr. Joyce Harrison, associate professor of psychiatry and behavioral sciences at Johns Hopkins School of Medicine in Baltimore.”
