Atonic (also called drop attack)
Atonic seizures produce an abrupt loss of muscle tone. Other names for this type of seizure include drop attacks, astatic or akinetic seizures. They produce head drops, loss of posture, or sudden collapse. In some children, only their head suddenly drops. After a few seconds to a minute the child recovers, regains consciousness. Because atonic seizures are so abrupt, without any warning, and because the people who experience them fall with force, atonic seizures can result in injuries to the head and face.
Protective headgear is sometimes used by children and adults; the seizures tend to be resistant to drug therapy.
What to Do:
No first aid is needed (unless there is injury from the fall), but if this is a first atonic seizure, the child should be given a thorough medical evaluation.
