[Pseudoperiodic EEG heralding a cefepime-induced encephalopathy]. / Electroencéphalogramme pseudopériodique dans l'encéphalopathie due au céfépime.

Electroencephalography is a useful tool for the diagnosis and follow-up of toxic and metabolic encephalopathies. A pseudo-periodic pattern can indicate various brain pathologies and causes of mental confusion. Among these, cefepime encephalopathy should always be considered, particularly in cases of renal failure, because of the reversibility of the symptoms at drug withdrawal.
