Epilepsy Flashcards
What is epilepsy?
Epilepsy is a neurological disorder characterized by recurrent and unprovoked seizures.
What is the prevalence and incidence of epilepsy?
Epilepsy affects approximately 1% of the population worldwide.
The incidence rate ranges from 20 to 70 per 100,000 people per year.
What are some common types of epilepsy?
Temporal lobe epilepsy
Absence epilepsy
Generalized tonic-clonic seizures
Focal seizures
What are some current ideas concerning the cellular basis for epilepsy?
Imbalance between excitatory and inhibitory neurotransmission
Abnormal ion channel function
Abnormal synaptic plasticity
Genetic mutations
What is the mechanism of action of anticonvulsant drugs?
Enhancing inhibitory neurotransmission (e.g., benzodiazepines, barbiturates)
Reducing excitatory neurotransmission (e.g., glutamate receptor antagonists)
Modulating ion channel function (e.g., voltage-gated sodium channel blockers, calcium channel blockers)
Potentiating GABA receptor activity (e.g., valproic acid)
