Dx, tx?
Status (medical emergency!)
Tx:

- Midazolam + Propofol
- Phenobarbital
Patient wihout Hx of epilepsy who comes to the ER with Lost of consciousness, Limb jerking, Bowel/bladder incontinence, tongue biting. He is not currently in seizure. The seizure lasted less than 5 minutes.
Next step?
CT EEG Look for cause (VITAMINS) - Vascular - Infxn - Trauma - Autoimmune - Metabolic - Idiopathic/withdrawal - Neoplasm - Sychiatric
Secondary causes of seizure
VITAMINS
- Vascular: stroke
- Infxn: encephalitis, meningitis
- Trauma: brain bleeds
- Autoimmune: cerebritis (lupus), vasculitis
- Metabolic: glucose, perfusion, oxygenation, Na, Ca
- Idiopathic/withdrawal: BDZ, alcohol
- Neoplasm
- Sychiatric
Definition of seizure status
seizure > 5 min; > 20 mins of post-ictal
First-line tx to prevent seizures
valproate, lamotrigine, levetiracetam
Child with recurrent episodes of loss of tone without LOC. Dx and tx?
Atonic epilepsy
Tx: Valproate
Boy with LOC without loss of tone. Dx and tx?
Absence
Tx: Ethosuximide
Tx of Myoclonic epilepsy?

Tx:
- Levodopa + carbidopa
- Dopamine agonists: ropinirole, pramipexole
Patient > 70 y-o non-functional patient with Bradykinesia, mask-like facies, trouble gatting started, Cogwheel rigidity, Resting pill-rolling tremor, Gait/postral instability (no postural correction–> falls).
