Which Brain Area Is Affected During an Atonic Seizure?
An atonic seizure may affect one or more areas in the brain. When it starts in a single region, it is known as a focal motor atonic seizure. This type typically involves a loss of tone in an area of the body. However, an atonic seizure usually affects both sides of the brain, which is also known as a generalized onset atonic seizure. When this happens, you may experience a sudden loss or drop of tone that affect the trunk, head, or the entire body. It is common to lose awareness during this period as well. A flare-up typically lasts no more than 15 seconds, but it would sometime persist up to a couple of minutes. After this period, you may quickly conscious and alert again. [3]
