distinguish epileptic seizures from other types of spells, such as psychogenic non-epileptic seizures, syncope (fainting), sub-cortical movement disorders and migraine variants; differentiate "organic" encephalopathy or delirium from primary psychiatric syndromes such as catatonia; serve as an adjunct test of brain death in comatose patients
