This long-term follow-up recruited participants from an earlier IEI-EMF provocation trial and re-administered the same questionnaire by telephone. Of 70 completers (35 IEI-EMF patients and 35 referents), 62.9% of patients reported recovery after an average of 1.8 years, with most recoveries described as spontaneous. Symptoms and EMF-related concerns generally decreased over time, and the authors suggest IEI-EMF may often be self-limited and consistent with nocebo mechanisms rather than direct EMF effects.
Looking for Biomarkers Which May Explain Idiopathic Environmental Intolerance Attributed to EMF (IEI-EMF): Does RF-EMF Exposure Influence Salivary Cortisol Response?
This randomized, double-blind, counterbalanced provocation study tested whether short-term RF-EMF exposure alters salivary cortisol in 72 predominantly young, healthy adults. Active exposure (2 W/kg peak SAR10g in head) showed no significant effect on cortisol compared with sham, and no sex differences were observed. The authors note that results may not rule out effects in populations not studied and encourage further research into plausible biological interactions.
Pilot questionnaire survey shows the lack of diagnostic criteria for electromagnetic hypersensitivity: a viewpoint
This viewpoint reports results from a pilot questionnaire survey of 142 self-declared EHS/IEI-EMF individuals and argues that current evidence and tools do not allow a definitive medical diagnosis of sensitivity to low-level wireless radiation. It notes that many reported diagnoses appear anecdotal and that tests used lack scientific proof for detecting such sensitivity. The article also considers individual sensitivity plausible and calls for controlled provocation and biochemical studies to develop diagnostic biomarkers.
Exposure Perception and Symptom Reporting in Idiopathic Environmental Intolerance Attributed to Electromagnetic Fields Using a Co-Designed Provocation Test
This co-designed provocation study in IEI-EMF volunteers evaluated whether perceived exposure and symptom reporting tracked actual EMF exposure under double-blind conditions. The abstract reports no consistent alignment between perceived exposure certainty or symptoms and true exposure status at the group level, with limited individual exceptions. Symptom reporting was related to certainty of being exposed for about half of participants, which the authors interpret as supporting a nocebo-type mechanism and motivating refinement of provocation protocols.
