Seizure and Parkinsons d r u g s Flashcards
Seizure involve both brain hemispheres
from the onset (1 Point) *
Focal onset seizure
Generalised onset seizure
Tonic clonic c o n v u l s i o n s
Generalized a b s e n c e seizure
Myoclonic seizure
Generalised onset seizure
brief episodes of unconsciousness (4-20
seconds, usually <10 seconds) with no
warning and immediate resumption of
consciousness (no postictal abnormality).

The specific actions of antiseizure drugs
on their targets are broadly described as:
(1 Point) *
modulation of voltage-gated sodium, calcium,
or potassium channels
enhancement of fast GABA-mediated synaptic
inhibition
modification of synaptic release processes
diminution of fast glutamate-mediated excita-

Inhibits COMT in CNS and peripheral
tissues that converts levodopa to 3-0-
