Two main types of epilepsy

Focal and generalized

4

Focal epilepsy

-only one part of the brain
-may have aura
-with or without LOC

5

3 types of focal epilepsy

-simple: no LOC
-complex: LOC
-secondary generalized

6

Generalized epilepsy

-entire hemisphere of the brain affected
-no warning/aura
-always LOC

7

Parietal seizure s/s

Tingling in the arms, face, legs
-inexplainable sensation

17

Status epilepticus

Continuous seizures with impaired consciousness in inter ictal period. Can last 15-30 minutes

18
