Abstract

Overview

In this study, we evaluated the effects of 2.45 GHz microwave radiation on cognitive dysfunction induced by vascular dementia (VaD). The experiment involves different rat groups including control, sham, and those exposed to Wi-Fi radiation.

Methodology

  • Rats were divided into four groups accordingly: control, sham, 2-VO, and 2-VO + Wi-Fi.
  • These groups were exposed to Wi-Fi signal at varying power densities and specific absorption rates, with the Wi-Fi modem positioned centrally 25 cm away from the cages, for 2 hours a day over 45 days.

Findings

The research found that the vascular dementia model led to impairments in spatial learning and memory as tested through radial arm maze and passive avoidance tasks. This was accompanied by a decrease in long-term potentiation and synaptic functions.

Remarkably, chronic exposure to Wi-Fi radiation not only enhanced cognitive performance but also recovered synaptic plasticity and hippocampal cell count in the 2-VO rats. This suggests a probable mitigatory effect of Wi-Fi radiation against VaD-induced cognitive degradation.

Conclusion

Despite the general perception of EMF radiation being hazardous, this study presents evidence of potential cognitive benefits in conditions of vascular dementia when exposed to controlled levels of 2.45 GHz microwave radiation. Further investigation into the optimum conditions and mechanisms would be beneficial.
