Atonic Seizures

Atonic Seizures

Atonic seizures (also called drop seizures, akinetic seizures or drop attacks), are a type of seizure that 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 indirect damage from falling. Electroencephalography can be used to confirm diagnosis. It is minor and relatively common, and can be indicative of Lennox-Gastaut syndrome (see Henri Gastaut). Atonic seizures can occur while standing, walking or sitting, and are often noticeable by a head drop (the neck muscles releasing) and damage sometimes results from hitting the face or head. As with common epileptic occurrences, no first aid is needed post-seizure, except in the instances where falling injuries have occurred. In some cases, a person may become temporarily paralyzed in part of his or her body. This usually does not last longer than 3 minutes.
