Understanding Epilepsy Seizures: Generalized Tonic-Clonic and Absence Types

Two major seizure types in epilepsy:

1. Generalized tonic-clonic seizures (GTCS): Sudden loss of consciousness, body stiffening (tonic phase), then rhythmic jerking (clonic phase). Most recognized seizure type.
2. Absence seizures: Brief (seconds) lapses in awareness, staring, subtle automatisms. No post-ictal confusion. Can occur many times daily. Common in childhood absence epilepsy.

Accurate classification guides medication selection (e.g., ethosuximide for absence; valproate, levetiracetam for GTCS).
