Lovejoy staging

Lovejoy staging

Neurology A system for staging severity of neurologic impairment in Reye syndrome

Lovejoy's classification–coma stages in Reye syndrome

I  Vomiting, lethargy, sleepiness

II Disorientation, delirium, combativeness, ↑ ventilation, ↑ reflexes, normal response to noxious stimuli

III  Obtunded, comatose, decorticate positioning; intact cranial nerves and oculomotor reflexes, inappropriate response to noxious stimuli

IV  Deepening coma, decerebrate rigidity, fixed dilated pupils, caloric stimulation causes dysconjugate eye movement, oculovestibular reflexes lost

V  Flaccid paralysis, deep tendon and respiratory reflexes absent, seizures
