Chronic exposure to 2.45 GHz microwave radiation improves cognition and synaptic plasticity impairment in vascular dementia model

Abstract

Overview

In this study, the team investigated the impact of 2.45 GHz microwave radiation on cognitive impairments caused by vascular dementia in rats. Vascular dementia was induced using a method known as bilateral-common carotid occlusion.

Methodology

Rats were divided into four groups: control, sham, vascular occlusion, and vascular occlusion with Wi-Fi exposure, with different numbers in each group. The Wi-Fi exposure involved a modem placed 25 cm away, exposing the animals for two hours daily over a span of forty-five days.

Findings

• Memory Assessments: Tests such as radial arm maze and passive avoidance highlighted that vascular dementia impaired learning and memory, which correlated with synaptic impairments.
• Synaptic Observations: The study noted decreases in long-term potentiation, basal-synaptic transmission, and other neurotransmission changes.
• Wi-Fi Exposure Results: Chronic Wi-Fi exposure facilitated recovery in learning and memory, enhanced synaptic plasticity, and increased neuronal density without altering basal synaptic transmission.

Conclusion

The study concluded that chronic exposure to Wi-Fi might mitigate cognitive degradation and synaptic loss in rats with vascular dementia, underscoring potential therapeutic effects of 2.45 GHz microwave radiation in this model.
