Functional brain MRI in patients complaining of EHS after long term exposure to EMF

Abstract

Overview

The study addresses the diagnostic use of functional magnetic resonance imaging (fMRI) in patients with reported electromagnetic hypersensitivity (EHS) after extended exposure to electromagnetic fields (EMF). Regular diagnostic tests often return normal results for these patients.

Findings

• Patient Background: Ten adult patients, all showing similar abnormalities on fMRI scans indicative of hyperconnectivity in specific brain regions.
• Materials and Methods: Initial testing with a standard MRI showed unremarkable results, pushing the use of fMRI that enabled the documentation of brain abnormalities.
• Results: Abnormalities were frequently noted in the anterior component of the default mode network located in the medial orbitofrontal area.

Conclusion

The fMRI scans revealed specific patterns indicating possible susceptibility to electrohypersensitivity. Additionally, patients often had prior head injuries and exposure to neurotoxic chemicals which may contribute to the onset of EHS.
