Complex Partial Seizures
Complex partial seizures begin in one area, or focus, of the brain, and then progress, or spread, to other areas of the brain, where they affect consciousness or cause staring, confusion, or loss of alertness. In some cases, they also cause aimless movements called automatisms, such as lip smacking or picking at clothes, the repetition of words or phrases, or inappropriate laughter.
