Episode description (with key takeaways)This episode explores antiseizure pharmacology as the art of stabilising excitable networks. Seizures arise when synchronous firing overwhelms inhibitory control; treatment therefore focuses on shifting thresholds, damping propagation, and restoring balance between excitation and inhibition. We move beyond drug lists to a small set of governing principles that explain why agents differ in seizure specificity, side-effect profiles, and suitability across the lifespan.

Key takeaways you’ll build and reuse throughout the series:

* Network instability, not single lesions: why seizures reflect circuit dynamics and spread.

* Core mechanisms, few in number: sodium channel modulation, calcium channel effects, GABA enhancement, and glutamate restraint.

* Thresholds and propagation: how drugs prevent initiation versus limit spread—and why this distinction matters clinically.

* Syndrome-guided choice: matching mechanism to seizure type rather than “broad coverage” reflexes.

* Trade-offs and vigilance: sedation, cognitive slowing, teratogenic risk, and interactions as predictable extensions of mechanism.
