Study Notes
Basic Information
- Epilepsy affects approximately 1% of the population, primarily without a known cause.
- Factors leading to epilepsy can include brain injury, stroke, brain tumors, and drug toxicity; a small portion is linked to genetic mutations.
- Epileptic seizures stem from excessive and abnormal activity of cortical nerve cells in the brain.
- Diagnosis often involves excluding other neurological conditions through brain imaging and EEG, though normal results do not rule out epilepsy.
- Antiepileptic drugs (AEDs) are effective for about 80% of patients, and lifelong treatment may be necessary.
- Establishing therapeutic drug plasma levels can take weeks, and poor compliance is a common reason for treatment failure.
- AEDs work best as monotherapy, offering higher effectiveness and fewer adverse effects.
- The introduction or removal of any drug should be gradual to prevent seizures during withdrawal.
- Some AEDs are teratogenic, necessitating adjustments or cessation of therapy during pregnancy.
Classification of Epilepsies
- Epilepsies are categorized by focal or generalized abnormal neuronal discharges.
- AED selection is based on seizure classification:
Simple Partial Seizures
- Localized discharge; consciousness remains intact.
- First-line therapies include Carbamazepine, Lamotrigine, and Valproic acid.
Complex Partial Seizures
- Localized discharge that spreads; consciousness is impaired.
- Same as above therapies apply here as well.
Tonic–Clonic Seizures (Grand Mal)
- Characterized by dramatic convulsions and loss of consciousness.
- First-line therapies include Valproic acid, Lamotrigine, and Carbamazepine.
Absence Seizures (Petit Mal)
- Sudden onset of altered consciousness lasting 10–45 seconds; may have hundreds of episodes daily.
- First-line therapies include Ethosuximide, Valproic acid, and Clonazepam.
Myoclonic Syndromes
- Present as lightning-like jerks of one or more extremities; can occur singly or in bursts.
- First-line therapies include Valproic acid and Lamotrigine.
Status Epilepticus
- Prolonged seizure (>20 minutes) of any type, commonly life-threatening generalized tonic–clonic.
- Treatment includes Phenytoin (administered intravenously in fosphenytoin form).
Mechanism of Action
- AEDs block Na+, K+, and Ca2+ channels in the brain and heart, reducing the spread of abnormal impulses and causing some degree of drowsiness.
- Therapeutic uses include management of partial and generalized seizures and treating status epilepticus.
- Phenytoin is also indicated for ventricular arrhythmia.
Basic Information
- Epilepsy affects approximately 1% of the population and generally has an unknown cause.
- Potential causes include brain injury, stroke, brain tumors, drug toxicity, and genetic mutations.
- Excessive and abnormal cortical nerve cell activity results in epileptic seizures.

- Establishing effective drug plasma levels can take weeks, and compliance is crucial for treatment success.
- AEDs are most effective and have fewer side effects when used as monotherapy.
- Gradual addition or withdrawal of any drug is recommended to avoid seizure occurrence.
- Some AEDs are teratogenic, potentially requiring therapy adjustments during pregnancy.
