Focal epilepsy

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.

Causes
The cause of the isolated disturbances results from the electrical signals
