Focal seizures

Focal seizures (also called partial seizures) are seizures which affect only a small part of the brain, and are split into two main categories; simple partial seizures and complex partial seizures

A simple partial seizure will often be a precursor to a larger seizure such as a complex partial seizure, or a tonic-clonic seizure. When this is the case, the simple partial seizure is usually called an aura.

Focal seizures are common in temporal lobe epilepsy.
