undercooked meat, myoclonus, dementia in young person
CJD
wet, wobbly, weird
normal pressure hydrocephalus - increased ICP, sx relieved with LP
how to differentiate labrynthitis from vestibular neuritis
labrynthitis = hearing loss
hearing loss, tinnitus, vertigo
meniere’s disease
meniere’s tx

cerebellar dysfunction
encephalopathy, ocular dysfunction, gait ataxia
wernicke encephalopathy due to THIAMINE deficiency
what are TWO important things to rule out in FIRST time seizure
metabolic causes (electrolytes, blood glucose) and toxic causes (urine drug screen)
if urine tox screen and metabolic labs are BOTH NORMAL, what next in first seizure workup?
