pe·tit mal sei·zure

obsolescent term for a cerebral seizure not manifested by tonic-clonic movements (that is, grand mal); formerly thought to be the clinical manifestation solely of a 3-second spike in wave pattern, as seen on electroencephalography, but now known to be associated with several different EEG patterns.
