Abstract

Non-thermal microwave/lower frequency electromagnetic fields (EMFs) act via voltage-gated calcium channel
(VGCC) activation. Calcium channel blockers block EMF effects and several types of additional evidence
confirm this mechanism. Low intensity microwave EMFs have been proposed to produce neuropsychiatric
effects, sometimes called microwave syndrome, and the focus of this review is whether these are indeed well
documented and consistent with the known mechanism(s) of action of such EMFs. VGCCs occur in very high
densities throughout the nervous system and have near universal roles in release of neurotransmitters and
neuroendocrine hormones. Soviet and Western literature shows that much of the impact of non-thermal
microwave exposures in experimental animals occurs in the brain and peripheral nervous system, such that
nervous system histology and function show diverse and substantial changes. These may be generated through
roles of VGCC activation, producing excessive neurotransmitter/neuroendocrine release as well as
oxidative/nitrosative stress and other responses. Excessive VGCC activity has been shown from genetic
polymorphism studies to have roles in producing neuropsychiatric changes in humans. Two U.S. government
reports from the 1970's-80's provide evidence for many neuropsychiatric effects of non-thermal microwave
EMFs, based on occupational exposure studies. 18 more recent epidemiological studies, provide substantial
evidence that microwave EMFs from cell/mobile phone base stations, excessive cell/mobile phone usage and
from wireless smart meters can each produce similar patterns of neuropsychiatric effects, with several of these
studies showing clear dose-response relationships. Lesser evidence from 6 additional studies suggests that
short wave, radio station, occupational and digital TV antenna exposures may produce similar neuropsychiatric
effects. Among the more commonly reported changes are sleep disturbance/insomnia, headache,
depression/depressive symptoms, fatigue/tiredness,dysesthesia, concentration/attention dysfunction, memory
changes, dizziness, irritability, loss of appetite/body weight, restlessness/anxiety, nausea, skin
burning/tingling/dermographism and EEG changes. In summary, then, the mechanism of action of microwave
EMFs, the role of the VGCCs in the brain, the impact of non-thermal EMFs on the brain, extensive
epidemiological studies performed over the past 50 years, and five criteria testing for causality, all collectively
show that various non-thermal microwave EMF exposures produce diverse neuropsychiatric effects.
