often unknown in younger people; in adults it’s often secondary to a specific even (CVA, tumor, trauma, etc)

subdivisions of seizures

2) generalized seizures

simple, complex
generalized seizures
absence; tonic-clonic; others
can focal become generalized?
yes
which primary subdivision affects both cerebral hemispheres?
generalized
most common seiures
1) complex partial
2) generalized tonic clonic
goal of antiseizure medications
SELECTIVE effect on hyperexcitable neurons
primary antiseizure agents- “front line”
1) phynytoin (Dilantin)
2) Carbamazepine (Tegretol)
3) Ethosuximide (Zarontin)
4) Valproates (Depakene, Divalproex, others)
other primary antisizure agents
benzos, barbiturates
most common antizeizure agent worldwide
