Atonic seizure
Encyclopedia : A : AT : ATO : Atonic seizure
Atonic seizures (also called drop seizures, drop attacks, or akinetic seizures), are a minor type of seizure. They consist of a brief lapse in muscle tone that are caused by temporary alterations in brain function. The seizures are brief - usually less than fifteen seconds. They begin in childhood and may persist into adulthood. The seizure itself causes no damage, but the loss of muscle control can result in falling and injuring oneself in that way. Electroencephalography can be used to confirm diagnosis. It is minor and relatively common, and can be indicative of Lennox-Gastaut syndrome (see Henri Gastaut).
