During these, people aren't aware of their actions. They might wander around seeming dazed, carrying out repetitive behaviors such as pulling at clothing, mumbling, running frantically or laughing uncontrollably. During a simple partial seizure, which can last from several seconds to several minutes, people remain conscious but might experience strange sensory distortions. For example, they might feel a breeze blowing through a room, even though the windows and doors are shut. Or they might hallucinate, or hear buzzing or feel a sense of unfounded anxiety or joy.
Stomach discomfort is another symptom.
About 3 percent of people with epilepsy experience simple partial seizures. Roughly 20 percent of convulsive seizures begin as partial seizures. Unlike partial seizures, generalized seizures encompass the entire brain from the start. In the first phase, people lose consciousness and their muscles become rigid. If standing, they may fall.
