Afterward, the person may be tired or confused for about 15 minutes and may not be return to normal function for hours.They usually last between 30 seconds and 3 minutes.Previously called secondarily generalized seizures, the new name for this is focal to bilateral tonic-clonic seizures. Some focal impaired awareness (complex partial) seizures can spread to both sides of the brain.Impairment of awareness is similar to the concept of impairment of consciousness.Some seizures make the person unable to move yet still aware of what is happening around them. A person's ability to respond may be impaired. Any decrease in awareness of the self or environment at any time during a seizure makes it a focal impaired awareness seizure. Awareness may be only partially impaired, rather than absent.If the symptoms are subtle, other people may think the person is just daydreaming.So even though their eyes are open and they may make movements that seem to have a purpose, they are not aware of them. The person loses awareness and stares blankly.In this case, the focal aware seizure quickly involves other areas of the brain that affect alertness and awareness.Some focal onset impaired awareness seizures (usually ones beginning in the temporal lobe) start with a focal aware seizure (previously call simple partial seizure), which is commonly called an aura.When they involve the frontal lobes, you may see bicycling movements of the legs or pelvic thrusting or other complex movements. Focal seizures can include involuntary movements called automatisms (aw-TOM-ah-TIZ-ums) like rubbing of the hands, lip-smacking, chewing movements.The seizures starting in the frontal lobe tend to be shorter than the ones from the temporal lobe.These seizures usually start in one area or group of brain cells, most often in the temporal lobe or frontal lobe of the brain.
