Focal epilepsy, also called partial epilepsy, is a seizure disorder in which seizures are preceded by an isolated disturbance of a cerebral function. Such disturbances may include a twitching of a part of the body, such as a limb; a deceptive or illusory sensation or feeling, or some other mental disturbance. It is a subtype of epilepsy.

The cause of the isolated disturbances results from the electrical signals that cause the seizure emanating from a specific part of the brain.

International Classification of Partial Seizures

2. Complex (interrupts consciousness)

3. Partial seizures evolving to a secondary generalized seizures
