lip-smacking, chewing, hand wringing, picking, and swallowing.
seizure lasts 30 seconds to 2 minutes.
Most people who have complex partial seizures do not remember having
them. After a seizure, the person will be confused or disoriented and may have
a hard time speaking and swallowing for several minutes.
People with photosensitive epilepsy have seizures that are triggered by:
bold, contrasting visual patterns (such as stripes or checks)
Anti-epileptic medicines are available to reduce the risk of seizure. But people with photosensitive epilepsy should take steps to minimize their exposure to seizure triggers.
Complex partial seizures are often confused with absence seizures, a
type of generalized seizure. Absence seizures, though, never begin with an
aura and last only 5 to 15 seconds. Also, a person is fully alert after an
absence seizure and may continue with whatever he or she was doing before the
seizure as though nothing has happened.
