Brain & Nervous SystemNo Effects Found

Effects of early-onset radiofrequency electromagnetic field exposure (GSM 900 MHz) on behavior and memory in rats.

Klose M et al. · 2014

German researchers exposed young rats to cell phone radiation (900 MHz) for nearly their entire lives, testing their learning and memory abilities at different ages. Despite using radiation levels up to 10 W/kg (much higher than typical phone exposure), they found no significant effects on behavior, memory, or brain development. This long-term study suggests that chronic cell phone radiation exposure starting in early development may not impair cognitive function.

Diverse Radiofrequency Sensitivity and Radiofrequency Effects of Mobile or Cordless Phone near Fields Exposure in Drosophila melanogaster.

Geronikolou S et al. · 2014

Researchers exposed fruit flies (Drosophila) to radiation from both mobile phones (900 MHz) and cordless phones (1880 MHz) to study reproductive effects. They found that mobile phone radiation significantly reduced egg laying in the second generation of flies, while cordless phone radiation showed only limited effects. The study suggests that lower frequency radiation may cause stronger biological impacts.

Mobile phone use and health symptoms in children.

Chiu CT, Chang YH, Chen CC, Ko MC, Li CY. · 2014

Researchers surveyed over 2,000 Taiwanese children aged 11-15 to examine whether mobile phone use was linked to health symptoms. They found that children who used mobile phones had 42% higher odds of experiencing headaches and migraines, and 84% higher odds of skin itching compared to non-users. Parents also reported that regular phone users had worse overall health compared to the previous year.

Decreased Survival of Glioma Patients with Astrocytoma Grade IV (Glioblastoma Multiforme) Associated with Long-Term Use of Mobile and Cordless Phones.

Carlberg M, Hardell L. · 2014

Swedish researchers analyzed survival data from 1,678 brain cancer patients and found that those who used mobile or cordless phones for more than 20 years had significantly worse survival rates. Patients with glioblastoma (the most aggressive brain cancer) who were long-term phone users were 2-3 times more likely to die sooner than non-users. This suggests that radiofrequency radiation from wireless phones may not only increase brain cancer risk but also make existing tumors more deadly.

Mobile telephone use effects on perception of verticality.

Bamiou DE et al. · 2014

Researchers tested whether mobile phone use affects people's sense of balance and spatial orientation by having participants wear phones against their ears for 30 minutes, then testing their ability to judge vertical and horizontal lines. They found that phones shifted people's perception of vertical away from the ear where the phone was placed, but this effect was due to the weight of the phone tilting the head rather than electromagnetic radiation.

Extremely low-frequency magnetic field exposure, electrical shocks and risk of Parkinson's disease.

van der Mark M et al. · 2014

Researchers studied whether exposure to extremely low-frequency magnetic fields (the type from power lines and electrical equipment) increases the risk of Parkinson's disease. They compared 444 Parkinson's patients with 876 healthy controls, examining both workplace and household electrical exposures. The study found no increased risk of Parkinson's disease from ELF magnetic field exposure or electrical shocks.

Neuronal Cellular Responses to Extremely Low Frequency Electromagnetic Field Exposure: Implications Regarding Oxidative Stress and Neurodegeneration.

Reale M et al. · 2014

Researchers exposed human brain cells to 50 Hz magnetic fields from household electricity and found they triggered harmful oxidative stress. The cells' natural defenses initially compensated, but failed when combined with other stressors, suggesting everyday EMF exposure may increase brain vulnerability to damage.

Effects of extremely low-frequency electric fields at different intensities and exposure durations on mismatch negativity.

Kantar Gok D et al. · 2014

Researchers exposed rats to 50 Hz electric fields (like those from power lines) for up to four weeks. High-intensity exposure significantly reduced brain responses that help detect sound changes, while increasing brain damage markers. This suggests electric field exposure may impair auditory processing abilities.

Investigation of EEG changes during exposure to extremely low-frequency magnetic field to conduct brain signals.

Shafiei SA, Firoozabadi SM, Tabatabaie KR, Ghabaee M. · 2014

Researchers exposed different areas of the brain to extremely low-frequency magnetic fields (3-45 Hz) at various intensities and measured changes in brain wave patterns using EEG. They found significant alterations in brain electrical activity, particularly reductions in alpha waves in frontal and central brain regions. The findings suggest these magnetic fields can measurably alter brain function, which the researchers propose could be developed into therapeutic protocols.

Neuronal Cellular Responses to Extremely Low Frequency Electromagnetic Field Exposure: Implications Regarding Oxidative Stress and Neurodegeneration.

Reale M et al. · 2014

Researchers exposed human brain cells to 50 Hz electromagnetic fields (the type from power lines) for up to 24 hours and found the cells produced more harmful molecules called free radicals and nitric oxide. While the cells initially tried to defend themselves by boosting antioxidant activity, this protection failed when the cells faced additional stress, leading to cellular damage that could contribute to brain diseases like Alzheimer's.

An evaluation of genotoxicity in human neuronal-type cells subjected to oxidative stress under an extremely low frequency pulsed magnetic field.

Giorgi G et al. · 2014

Italian researchers exposed human brain cells to power line frequency magnetic fields (50 Hz) while simultaneously stressing them with hydrogen peroxide. Over 72 hours, the magnetic field exposure did not increase DNA damage beyond what the chemical stress alone caused, suggesting power-frequency fields may not worsen cellular damage.

Long-term (up to 20years) effects of 50-Hz magnetic field exposure on blood chemistry parameters in healthy men

Unknown authors · 2012

French researchers tracked 15 healthy men exposed to 50 Hz magnetic fields (power line frequency) for up to 20 years, comparing their blood chemistry to unexposed controls. Men with exposures above 0.3 microtesla showed significant changes in sodium, chloride, phosphorus, and glucose levels during nighttime blood sampling. The study suggests long-term power frequency exposure may alter basic blood chemistry, though the health significance remains unclear.

Evaluation of Chromosomal Alteration in Electrical Workers Occupationally Exposed to Low Frequency of Electro Magnetic Field (EMFs) in Coimbatore Population, India

Unknown authors · 2012

Indian researchers studied 50 electrical workers exposed to low-frequency electromagnetic fields from transformers and distribution stations, comparing them to 20 unexposed controls. They found significantly more chromosomal damage and genetic abnormalities in the electrical workers' blood cells, with damage increasing based on years of exposure. This suggests chronic occupational EMF exposure may increase genetic damage and cancer risk.

DNA & Genetic DamageNo Effects Found

Gene expression profiles in white blood cells of volunteers exposed to a 50 Hz electromagnetic field

Unknown authors · 2012

Researchers exposed 17 young men to 50 Hz magnetic fields (the type from power lines) at 62 microT for 2 hours and analyzed their white blood cells for changes in gene expression. They found no consistent genetic changes from the EMF exposure, even when looking at 16 genes previously reported to respond to electromagnetic fields. The only stress response detected was from the experimental procedure itself, not the EMF exposure.

Treating cancer with amplitude-modulated electromagnetic fields: a potential paradigm shift, again?

Blackman C · 2012

Scientists tested whether amplitude-modulated electromagnetic fields (AM-EMF) could slow cancer cell growth in laboratory studies. They found that specific AM-EMF frequencies reduced growth rates in liver and breast cancer cells while leaving healthy cells unaffected. This builds on earlier clinical trials showing the same approach helped stabilize advanced cancers in patients.

Is human saliva an indicator of the adverse health effects of using mobile phones?

Unknown authors · 2012

Researchers compared saliva samples from 20 long-term mobile phone users (averaging 12.5 years of use) with deaf individuals who don't use phones. Mobile phone users showed significantly higher oxidative stress markers in their saliva, plus reduced saliva flow and protective proteins. This suggests phone radiation may damage cells near the ear through oxidative stress.

Long-term (up to 20years) effects of 50-Hz magnetic field exposure on blood chemistry parameters in healthy men

Unknown authors · 2012

French researchers tracked blood chemistry in 15 healthy men exposed to 50 Hz magnetic fields for up to 20 years, comparing them to unexposed controls. Men with exposures above 0.3 microTesla showed significant changes in sodium, chloride, phosphorus and glucose levels during nighttime blood sampling. The study suggests long-term power line frequency exposure may alter basic blood chemistry, though the health significance remains unclear.

Effects of extremely low frequency electromagnetic radiation on cardiovascular system of workers

Unknown authors · 2012

Chinese researchers studied 642 workers exposed to extremely low frequency electromagnetic fields and compared them to 188 unexposed controls. Workers in high-EMF environments showed significantly higher rates of cardiovascular abnormalities, including irregular heart rhythms and elevated liver enzymes that can indicate heart stress. The study suggests workplace EMF exposure may harm workers' cardiovascular health.

Impact of high electromagnetic field levels on childhood leukaemia incidence

Teepen JC, van Dijck JA · 2012

This comprehensive 2012 review analyzed multiple studies linking electromagnetic fields to childhood leukemia, finding a 40-70% increased risk when children are exposed to power line frequencies above 0.3 microTesla. The researchers estimated that EMF exposure may contribute to nearly 2% of all childhood leukemia cases globally, with higher rates in North America and Brazil.

Gene expression profiles in white blood cells of volunteers exposed to a 50 Hz electromagnetic field

Unknown authors · 2012

Researchers exposed 17 male volunteers to 50 Hz electromagnetic fields (62 μT) for 2 hours and analyzed gene expression changes in their white blood cells using microarray technology. The study found no consistent gene expression changes from EMF exposure, including no responses in 16 genes previously reported as EMF-sensitive. The only stress response detected was temporary cortisol elevation that occurred equally during both real and sham exposures.

Incidence trends in the anatomic location of primary malignant brain tumors in the United States: 1992-2006

Unknown authors · 2012

Researchers analyzed brain cancer patterns from three major U.S. cancer registries between 1992-2006, tracking where tumors developed in the brain. They found significant increases in deadly glioblastoma tumors specifically in the frontal and temporal lobes (areas closest to where phones are held), while tumors in other brain regions decreased. The cause of these location-specific trends remains unknown.
