-A subset of AHIs cannot be easily explained by known environmental or medical conditionsand could be due to external stimuli.
-Pulsed electromagnetic energy, particularly in the radiofrequency range, plausibly explains the core characteristics, although information gaps exist.
-Ultrasound also plausibly explains the core characteristics, but only in close-access scenariosand with information gaps
-Psychosocial factors alone cannot account for the core characteristics, although they maycause some other incidents or contribute to long-term symptoms.
