Answer

See the list below:

  • The EEG often exhibits a disturbance of normal sleep rhythms and focal or generalized slowing. Epileptiform discharges are rarely seen in ADEM. [47] The absence of such abnormalities during the first bout of acute disseminated demyelinating illness in a child may increase the suspicion for ultimate MS diagnosis. Similar EEG abnormalities are found in adult ADEM. [84]

  • Visual evoked potentials (VEP) may prove helpful when optic neuritis is suspected but not apparent on clinical examination.
