Benign occipital epilepsy is a rare, genetic neurological disorder characterized by visual seizures and occipital epileptiform paroxysms reactive to ocular opening which present in infancy to mid-adolescence. Vomiting, tonic eye deviation and impairment of consciousness are typically associated with the Panayiotopoulos type, while visual hallucinations, ictal blindness and post-ictal headache are commonly observed in the Gastaut type. Electroencephalographic findings in both types are similar and include bilateral, synchronous, high voltage spike-wave complexes in a normal background activity located predominantly in the occipital lobes. Is a True Occipital lobe epilepsy Inferred relationship Some
A rare occipital epilepsy syndrome with onset most commonly between four and seventeen years (mean eleven years; range one to fifty years). Seizures are triggered by photic stimuli such as flickering sunlight. Focal sensory visual seizures which may evolve to bilateral tonic-clonic seizures are mandatory for the diagnosis. Focal sensory visual semiology includes colored spots, formed visual hallucinations, or visual blurring/loss that moves across the visual field. There is associated head and eye version. Seizures may progress to a cephalic sensation (including headache), autonomic epigastric sensation or vomiting, and impaired awareness or to a focal to bilateral tonic-clonic seizure. Seizures are typically brief (less than three minutes), although prolonged seizures may occur. Development and cognition are typically normal. Neurological examination is normal. The background electroencephalogram (EEG) activity is normal. Occipital epileptiform abnormalities facilitated by eye closure and intermittent photic stimulation are seen. Epileptiform activity is elicited by sleep deprivation and by sleep. MRI is normal or has nonspecific findings. Is a True Occipital lobe epilepsy Inferred relationship Some
