Wireless communication devices are ubiquitous in today’s world, and exposure to radiofrequency electromagnetic fields (RF-EMF) has increased as a result. However, the potential health effects of this exposure, particularly on neurological functions, remain a subject of ongoing debate. This study aimed to investigate the relationship between adolescents’ memory performance and their individual brain dose of microwave radiation from wireless communication.
Methodology
A cohort of Swiss adolescents participated in this prospective study, which estimated their RF-EMF brain dose using advanced modeling techniques. Researchers assessed changes in verbal and figural memory scores over a one-year period and analyzed the relationship with RF-EMF exposure and media usage. Additional analyses were conducted to account for phone call ear preference and different media usage groups.
Results
The study found that increased estimated cumulative RF-EMF brain dose scores were associated with decreased figural memory scores, particularly among right-side phone users. No consistent patterns or significant associations were observed between media usage unrelated to RF-EMF and memory scores. However, a positive association (albeit nonsignificant) was noted between data traffic duration and verbal memory.
Conclusions
The study’s results suggest a potential adverse effect of RF-EMF brain dose on cognitive functions, particularly in brain regions most exposed during mobile phone use. However, these findings require confirmation in other populations. To minimize potential long-term risks, users are advised to avoid high brain-exposure situations, such as using a mobile phone with maximum power close to the ear.

Increased Vulnerability of Children and Teens to RF-EMF Exposure
Children and teenagers may be at a greater risk of experiencing adverse effects from RF-EMF exposure due to several factors:
Developing Brains: The brains of children and adolescents are still in the process of maturation, undergoing rapid growth and development. This makes their brains potentially more susceptible to external influences, such as RF-EMF, which could disrupt the delicate balance of biological processes.
Higher Absorption Rates: Research has shown that children and teenagers tend to have higher rates of RF-EMF absorption in their brains compared to adults. This is due to their thinner skull bones, smaller head size, and higher tissue conductivity, which allows for deeper penetration of electromagnetic fields.
Longer Lifetime Exposure: The younger generation is exposed to wireless communication devices from an early age, leading to a longer lifetime exposure to RF-EMF. The long-term consequences of this exposure remain largely unknown, but the potential for cumulative effects on cognitive functions and overall health cannot be ruled out.
Prolonged and Frequent Use: Children and teenagers are known for their extensive use of mobile phones and other wireless devices, often for long durations and at close proximity to their heads. This prolonged and frequent usage increases their overall RF-EMF exposure, potentially elevating the risk of adverse effects on cognitive functions.
Crucial Period for Cognitive Development: Adolescence is a critical period for cognitive development, with memory functions playing a vital role in learning and academic success. Any disruption to this process, such as that potentially caused by RF-EMF exposure, could have significant long-term consequences on cognitive abilities and academic performance.
ADHD Findings and Neuronal Changes: Exploring the Link with RF-EMF Exposure
Several studies have investigated the potential relationship between ADHD symptoms and RF-EMF exposure, while others have focused on the possible changes in neuronal structures and functions. Here, we highlight key findings from these studies:
- ADHD and RF-EMF Exposure: Some studies have reported an association between ADHD symptoms and increased exposure to RF-EMF from wireless devices. However, the findings are not consistent across all studies, and it remains unclear whether RF-EMF exposure directly contributes to the development or exacerbation of ADHD symptoms, or if other factors, such as increased screen time and reduced physical activity, play a more significant role.
- Changes in Neuronal Structure and Function: Research has demonstrated that RF-EMF exposure can affect neuronal structures and functions in animal studies. These studies have shown that RF-EMF can cause alterations in neurotransmitter levels, neural activity, and even structural changes in the brain. However, the relevance of these findings to human exposure and the potential impact on cognitive functions, such as attention and memory, remain uncertain.
- Oxidative Stress and Neuroinflammation: Some studies suggest that RF-EMF exposure may lead to oxidative stress and neuroinflammation, which can contribute to neuronal dysfunction and the development of ADHD symptoms. However, further research is needed to confirm these findings and to determine the biological mechanisms underlying these potential effects.
- The Need for Longitudinal Studies: Longitudinal studies are necessary to establish a clearer understanding of the potential relationship between RF-EMF exposure and ADHD symptoms, as well as possible changes in neuronal structures and functions. These studies should take into account confounding factors, such as genetic predisposition, lifestyle factors, and other environmental exposures, to better understand the potential impact of RF-EMF on cognitive and behavioral outcomes.
In conclusion, while some studies suggest a possible link between RF-EMF exposure and memory loss, ADHD symptoms, and changes in neuronal structures and functions, the evidence is still inconclusive. Further research is required to determine the true extent of these associations and the potential risks associated with long-term exposure to RF-EMF from wireless communication devices.
