Anti-Epileptic Drugs - Glutamate Flashcards

(34 cards)

1
Q

With Epilepsy, there is a neuronal imbalance that causes increased CNS excitation. What are the molecules and their changes in levels that are associated with that?

A
Glutamate/Aspartate = increased = more excitation
GABA = decreased = less inhibition
