Alzheimer’s Disease & WiFi

November 6, 2025

Could your WiFi increase your risk of developing Alzheimer’s Disease?

New research investigates this possibility.

In their study, Victor Cruz and team reviewed 49 studies to determine whether WiFi could affect genes that are involved in the development of Alzheimer’s Disease (AD).

They found two particular genes of interest.

  • The first is the APOE gene which the authors describe as ‘the most well-known genetic risk factor for late-onset AD.’
  • The second is the GSK3B (glycogen synthase kinase 3 beta) gene. ‘Dysfunctional GSK3B activity is linked to accelerated neurodegeneration in AD’, they wrote.

Cruz and team say that ‘… exposure to 2.4 GHz electromagnetic fields emitted by Wi-Fi devices could have an indirect impact on the regulation of genes involved in Alzheimer’s disease, particularly those related to oxidative stress and cellular homeostasis. Although a direct relationship has not been demonstrated, current findings suggest that the alteration of genes such as GSK3B and APOE, which are fundamental in neurodegeneration, could be exacerbated by chronic exposure to this radiation.’

How could this happen?

The authors explain, ‘One of the main concerns is that chronic exposure to 2.4 GHz EMF could induce cumulative damage to the expression of key genes involved in DNA repair and cellular metabolism regulation. This damage could create an environment conducive to synaptic dysfunction and the accumulation of misfolded proteins, characteristic processes of AD (52). Although conclusive evidence of a direct relationship between 2.4 GHz radiation and Alzheimer’s disease is still lacking, the alteration of cellular processes related to oxidative stress and cellular homeostasis presents a plausible avenue for future research. It is important to note that although some of the genes involved in AD, such as APOE and GSK3B, are linked to cellular functions that could be altered by EMF exposure…’

Radiation-free internet for homes and workplaces

Don’t expose your family and workers to WiFi radiation unnecessarily; use radiation-free modems and routers for internet instead.
