FOCAL SEIZURES.

An encyclopedia entry for "Focal Seizures" is presented. It refers to partial seizures in patients with localization-related epilepsy (LRE). Factors to consider in distinguishing between various kinds of focal seizures include structural lesions, maturational factors, modes of precipitation, and underlying pathophysiologic mechanisms. Trauma and vascular malformations in younger age groups are some of the frequent symptomatic causes of focal seizure.
