Occipital epilepsy is a neurological disorder that arises from excessive neural activity in the occipital lobe of the brain that may or may not be symptomatic. Occipital lobe epilepsy is fairly rare, and may sometimes be misdiagnosed as migraine when symptomatic. Epileptic seizures are the result of synchronized neural activity that is excessive, and may stem from a failure of inhibitory neurons to regulate properly.[1]
It is a disorder with focal seizures in the occipital lobe of the brain. There are two main types of this epilepsy, each consisting of focal seizures- Gastaut and Panayiotopoulos (Pan.).[2] Other names for the Gastaut type include benign epilepsy of childhood with occipital paroxysms (BECOP) and late-onset occipital epilepsy. Pan. is also known as self-limiting focal epilepsy of childhood with occipital paroxysms and early-onset benign partial epilepsy with occipital paroxysms. There may be no known cause of this type of seizure, but these epilepsies may occur for a variety of reasons, such as brain tumors, infection, trauma and lesions, and idiopathic onset.[3] Seizures originate in the occipital lobe and account for 5 to 10 percent of all epileptic seizure types. Generally, this type of epilepsy can have an onset anywhere from 1–17 years old in children, but the patient prognosis is good. Since the event is located in the occipital lobe, symptoms may occur spontaneously and include visual stimuli.
