Because they happen so quickly, it’s very easy not to notice simple absence seizures — or to confuse them with daydreaming or not paying attention.
Atypical absence seizures: During an atypical absence seizure, a person will experience a change in muscle tone which or make some kind of movement in addition to staring into space. Movements may include blinking, chewing, or hand gestures. An atypical absence seizure may last up to 20 seconds.
