Answer

Answer

Absence should be differentiated from atypical absence seizures, which usually are seen in patients with Lennox-Gastaut syndrome. The EEG in atypical absence seizures shows a less abrupt onset and offset than in typical absence seizures. Furthermore, the EEG background is slow, and the duration of discharges is shorter.
