Focal impaired-awareness seizures are often longer and may have postictal confusion.
B. Syncope
Syncope is usually associated with postural trigger and loss of tone.
C. Complex migraine
Migraine episodes last far longer and have different symptoms.
D. Childhood absence epilepsy (correct)
Correct. Brief frequent spells with immediate recovery and 3-Hz pattern are typical.
