EEG changes during fever produced by inductothermy (fever cabinet) in patients with neurosyphilis

Hyperthermia-Induced Changes in EEG of Anesthetized Mice Subjected to Passive Heat Exposure

“…The present study demonstrates a gradual reduction in signal intensity as the temperature increases, but in no case was there a suppression (Cabral et al, 1977) or an increase (Lin et al, 1953) of EEG signal as previously reported, indicating that those extreme results could be the consequence of the specific pathology. On the other hand, a gradual increase from 39 to 41 • C followed by an abrupt decrease in EEG amplitude has also been reported in curarized rats (Ten Cate et al, 1949).…”

“…Regarding physiology, it is known that body temperature is an important factor driving neuronal activity, as the metabolism and integrity of brain cells depend on it (Mrozek et al, 2012). EEG during febrile status has been intensively studied and analyzed and is usually related to other pathological processes, such as seizures, infections, cancer treatment (Barlogie et al, 1979;Reilly et al, 1980), or syphilis (Lin et al, 1953). However, the effect of hyperthermia on EEG in healthy subjects has not been deeply studied, even when fever is a common process that all of us suffer from at some point in life.…”
