Idiopathic localization-related epilepsies are summarized according to the current classification of the International League Against Epilepsy. The recognition of a distinctive idiopathic epileptic syndrome occurring in children and featuring ictal vomiting, partial motor seizures, and occipital spikes is emphasized. Atypical evolutions of benign partial epilepsy of childhood and status of BPECS. Acquired epileptic aphasia has also been correlated to BPECS, and all these syndrome (CSWS). Childhood epilepsy with occipital paroxysms may also evolve into CSWS and into clinical and EEG status. Differential diagnosis of BPECS includes children with fortuitous associations of BPECS with cerebral palsy and the occurrence of a clinicoelectroencephalographic phenotype of BPECS in children with progressive and nonprogressive structural brain pathologies. Childhood epilepsy with occipital paroxysms should be differentiated from cerebrovascular abnormalities mitochondrial myophathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS), and the syndrome of posterior cerebral calcifications, epilepsy, and celiac disease.

Childhood epilepsy with occipital paroxysms is an age-related idiopathic focal epilepsy. Occipital EEG paroxysms are considered necessary for diagnosis. We carried out a close clinical and EEG follow-up (range, 2-12 years; mean, 6 years 7 months; median, 7 years) in 24 patients (age range, 4-19 years; mean, 11 years 8 months; median, 11 years). In five children with early seizure onset and particularly benign prognosis without any treatment, EEG abnormalities appeared 3-10 months after the first seizure. Four of them exhibited the ictal pattern of versive seizures with vomiting. Our findings confirm that in the early idiopathic focal seizure disorders, interictal EEG abnormalities may be lacking at the beginning of the disorder.

Childhood epilepsy with occipital paroxysms (CEOP) is an idiopathic localization-related epilepsy. A typical seizure in CEOP begins with visual symptoms, followed by hemiclonic seizures, complex partial seizures or generalized tonic-clonic seizures. Benign nocturnal childhood occipital epilepsy (BNCOE), characterized by nocturnal seizures with tonic deviation of the eyes followed by vomiting, has the same electroencephalographic features as CEOP. In this study, we report the seizure symptoms and electroencephalographic features of 21 cases with CEOP or BNCOE. Out of these patients, nine had BNCOE, six had CEOP, four had CEOP and BNCOE and the remaining two belonged to the incomplete syndrome because of no paroxysmal discharges in EEG. When the patients with BNCOE awoke from sleep, they had tonic deviation of the eyes and could describe visual symptoms. Patients with CEOP had seizures beginning with visual symptoms followed by loss of consciousness but no generalized convulsions. In three cases, in addition to the occipital spikes, independent centro-temporal spikes were recorded and in another three cases generalized spike-wave discharges were recorded. Such a combination suggests the idiopathic nature of these epilepsies. We concluded that in the diagnosis of CEOP and BNCOE, the seizure symptomatology is important even if the EEG can be considered normal.

Benign occipital epilepsy of childhood is an idiopathic partial epilepsy syndrome with elementary visual symptomatology, frequently associated with other ictal phenomena. Seizures are usually followed by postictal headache and are often associated with interictal occipital rhythmic paroxysmal EEG activity that appears only after eye closure. In some children the ictal visual symptoms or the interictal EEG abnormalities may not be demonstrated. The clinical and/or EEG manifestations of other forms of idiopathic partial or generalized epilepsy may be found in association. Occipital spikes in non-epileptic children with defective vision, occipital slow spike-and-wave found in some patients with the Lennox-Gastaut syndrome, focal epilepsy due to occipital lesions, seizures originating in the temporal lobe secondary to an occipital abnormality, and complicated or basilar migraine must be considered in the differential diagnosis. Early-onset benign occipital epilepsy or seizure susceptibility syndrome deserves to be considered separately. It has been defined by Panayiotopoulos as consisting of brief, infrequent attacks or prolonged status epilepticus and characterized by ictal deviation of the eyes and/or head and vomiting, occurring in children usually between the ages of 3 and 7 years. Advances in molecular genetics will help decide whether these two disorders are indeed distinct. Benign occipital and benign rolandic epilepsy are commonly associated with migraine. The selective involvement of the occipital lobe in migraine has not been fully explained. The association between benign occipital epilepsy and migraine is likely related to this underlying mechanism as well. The "fixation off" phenomenon or blocking of occipital epileptic discharges by eye opening is not specific to benign occipital epilepsy of childhood and may be found in symptomatic epilepsies as well. Migraine and epilepsy are distinct disorders, both as far as their pathophysiologic mechanisms and clinical symptomatology are concerned. There is however an overlap in some patients and a causal relationship may exist in some, leading to clinically distinct migraine epilepsy syndromes. Here too, clarification of the molecular basis of migraine and of epilepsy will throw light on the nature of the relationship between the two conditions.
