Can epilepsy that causes the patient to faint but not seize?

Yes, there is a type of epilepsy called "absence seizures" or "petit mal seizures" that can cause a person to lose consciousness for a brief moment, but the body does not exhibit the typical convulsive movements associated with traditional seizures. During an absence seizure, a person may appear to be staring into space or have a blank expression for a few seconds before resuming normal activity. These seizures often occur in clusters, with multiple episodes happening in a short period of time.

Absence seizures are relatively common, especially in children and adolescents. They are usually controlled well with medication and may go away completely over time.
