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.
(1) Onset of seizures is mainly with autonomic symptoms, which are not occipital lobe manifestations. (2) Of occipital symptoms, only deviation of the eyes may originate from the occipital regions, but this rarely occurs at onset. Visual symptoms are exceptional and not consistent in recurrent seizures. (3) Interictal occipital spikes may never ...
Focal seizures (also called partial seizures[1] and localized seizures) are seizures that affect initially only one hemisphere of the brain. [2][3] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes. A focal seizure is generated in and affects just one part of the ...
Temporal lobe resection acts as a treatment option for patients with temporal lobe epilepsy, or those whose seizure focus is in the temporal lobe.

Syndromes are characterized into 4 groups based on epilepsy type: [1] a. Generalized onset epilepsy syndromes. These epilepsy syndromes have only generalized-onset seizures and include both the idiopathic generalized epilepsies (specifically childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy and epilepsy with generalized tonic- clonic seizures alone), as well as ...
Reflex seizure. Reflex seizures are epileptic seizures that are consistently induced by a specific stimulus or trigger, making them distinct from other epileptic seizures, which are usually unprovoked. [4][3] Reflex seizures are otherwise similar to unprovoked seizures and may be focal (simple or complex), generalized, myoclonic, or absence ...
Photopsia is the presence of perceived flashes of light in the field of vision. It is most commonly associated with: [4] Vitreous shrinkage or liquefaction, which is the most common cause of photopsia, causes a pull in vitreoretinal attachments, irritating the retina and causing it to discharge electrical impulses.
