Absence seizures : Symptoms

image

An indication of simple absence seizure is a vacant stare, which may be mistaken for a lapse in attention that lasts about 10 seconds, though it may last as long as 20 seconds, without any confusion, headache or drowsiness afterward. Signs and symptoms of absence seizures include:

  • Sudden stop in motion without falling
  • Lip smacking
  • Eyelid flutters
  • Chewing motions
  • Finger rubbing
  • Small movements of both hands

Afterward, there’s no memory of the incident. Some people have many episodes daily, which interfere with school or daily activities.

A child may have absence seizures for some time before an adult notices the seizures, because they’re so brief. A decline in a child’s learning ability may be the first sign of this disorder. Teachers may comment about a child’s inability to pay attention or that a child is often daydreaming.
