The peculiar feeling which persons who are subject to epileptic seizures (see EPILEPSY) experience just before the onset of an attack. It may be a sensation of a cold breeze, a peculiar smell, a vision of some animal or person, or an undeﬁnable sense of disgust. An aura gives warning that a ﬁt is coming and may enable a place of safety or seclusion to be reached. It may also occur as a precursor to a MIGRAINE headache.
