what are absence seizures

Absence seizures, also known as petit mal seizures, are a type of generalized seizure that cause a brief lapse in consciousness. They are more common in children than adults and usually last for a few seconds, although they can last up to 20 seconds. During an absence seizure, a person may stare blankly into space, make subtle movements such as lip smacking or finger rubbing, or experience eyelid flutters or chewing motions. Afterward, there is usually no confusion, headache, or drowsiness. Absence seizures can interfere with school or daily activities and may be mistaken for lack of attention or daydreaming. Most children outgrow absence seizures during their teen years, but some may require anti-seizure medication throughout life.
