What are generalized tonic seizures?

ANSWER

During tonic seizures, the muscles in your arms, legs, or trunk tense up. These usually last less than 20 seconds and often happen when you’re asleep -- but if you’re standing up at the time, you can lose your balance and fall. These are more common in people who have a type of epilepsy known as Lennox-Gastaut syndrome, though people with other types can have them as well.
