*Tx: [[AEDs]] (no first line agent, decide on a case-by-case basis). For [[status epilepticus]], ABCs, give IV lorazepam, fosphenytoin if seizure persists, consider induced coma if all else fails.

*Must have SBP > 100, temp > 36°C, PaCO2 35-45, euvolemia, off all sedatives
*If above conditions are met, test for brainstem reflexes: pupillary reflex (II, III), corneal reflex (V, VII), doll's eye reflex (III, IV, VI, VIII), and gag reflex (IX, X)
*If no brainstem reflexes, do apnea test: positive if no breathing when PaCO2 is 60 mmHg or 20 mmHg higher than patient's baseline
*If apnea test is equivocal, can do four vessel angiography, EEG, or duplex US
*Rule out secondary causes of coma (e.g. test for severe hypoglycemia)

*H&P: Differentiate between dizziness and lightheadedness. Peripheral and central vertigo present differently. Peripheral is positional, improves with eye fixation, and
