Benign rolandic epilepsy: clinical and electroencephalographic correlates
RIESGO, RUDIMAR DOS SANTOS;JAYAKAR, PRASANNA;ROTTA, NEWRA TELLECHEA;
Arquivos de Neuro-Psiquiatria , 2000, DOI: 10.1590/S0004-282X2000000500010
Abstract: benign rolandic epilepsy (bre) is known for its dissociation from structural alterations. nevertheless, the number of cases with reported organic lesions has been increasing. this led to the creation of two subgroups, "benign" and "non benign" bre, and resulted in the need for additional parameters to define electrographic benignity. we assessed the possible associations between interictal electroencephalographic findings and clinical behavior in 60 bre cases, testing four parameters of electrographic benignity (paroxysm morphology, horizontal dipole, base rhythms, laterality of rolandic spikes). we also assessed the relationship between neuroimaging findings and electrographic and clinical classifications, and found a statistically significant association (sensitivity=73.5%; specificity=81.8%; positive predictive value=94.8%; negative predictive value=40.9%). three of the electrographic parameters proposed were associated with clinical classification: paroxysm morphology, horizontal dipole, and base rhythms. cases electrographically classified as benign have 21 times more chances to be equally classified as clinically benign according with the tested criteria.

Abstract: Benign rolandic epilepsy (BRE) is known for its dissociation from structural alterations. Nevertheless, the number of cases with reported organic lesions has been increasing. This led to the creation of two subgroups, "benign" and "non benign" BRE, and resulted in the need for additional parameters to define electrographic benignity. We assessed the possible associations between interictal electroencephalographic findings and clinical behavior in 60 BRE cases, testing four parameters of electrographic benignity (paroxysm morphology, horizontal dipole, base rhythms, laterality of rolandic spikes). We also assessed the relationship between neuroimaging findings and electrographic and clinical classifications, and found a statistically significant association (sensitivity=73.5%; specificity=81.8%; positive predictive value=94.8%; negative predictive value=40.9%). Three of the electrographic parameters proposed were associated with clinical classification: paroxysm morphology, horizontal dipole, and base rhythms. Cases electrographically classified as benign have 21 times more chances to be equally classified as clinically benign according with the tested criteria.

Abstract: to study clinical and eeg features of children with ictal vomiting and no underlying brain lesions (panayiotopoulos syndrome). the subjects were 36 children aged 2-13 years. the onset of seizures occurred between 1 and 5 years of age. fourteen children (38.8%) had a single seizure. fourteen children (38.8%) had autonomic status epilepticus. impairment of consciousness was reported in 30 (83.3%) children, eye deviation in 10 (27.7%) other autonomic symptoms and head deviation in 9, generalization in 8, visual symptoms in one child, and, speech arrest or hemifacial motor symptoms in 8 cases. the eeg showed occipital spikes or spike-wave complexes in 27 (75.0%) children, blocked by opening of the eyes in 8 (22.2%) cases. nine patients (25%) also had rolandic spikes and 3 had extraoccipital spikes. six (16.6%) patients had normal eeg. no clinical differences were observed between patients having occipital or extraoccipital spikes. in children only with autonomic seizures, the spikes are predominantly occipital but blockage by opening of the eyes is a less frequent feature. in some children there is an overlapping of different focal childhood idiopathic syndromes.

Abstract: occipital epileptiform activity blocked by eyes opening (oeab) is primarily observed in childhood epilepsy with occipital paroxysms but may be also found in cases of benign childhood epilepsy with centrotemporal spikes, cryptogenic/symptomatic partial epilepsies, idiopathic generalized epilepsies and in patients with no seizures. we studied comparatively eeg and clinical features of 20 patients with oeab and 120 patients with occipital epileptiform activity not suppressed by eyes opening (oea). epileptiform activity (oea or oeab) was registered until the 7 years of age in 67.5% of the patients with oea and in 45% of the patients with oeab. epileptic seizures began before 4 years of age in 44.4% of the cases with oea and in 14.2% in the group oeab. febrile convulsions alone occurred only in the oea group (12.5%). developmental retardation was referred in 27 patients with oep. the occurrence of spike and wave complexes was statistically more frequent among patients with oeab (80.0%) as opposed to patients with oea (17.5%), our findings suggest clinical and electroencephalographic differences between children with oea and oeab.

Journal of Epilepsy and Clinical Neurophysiology , 2009, DOI: 10.1590/S1676-26492009000100008
Abstract: introduction: the new proposed classification of ilae task force (2001) proposes that the occipital epilepsies should be split into two subtypes: an early-onset benign childhood occipital epilepsy (or panayiotopoulos type) and late-onset childhood occipital epilepsy (or gastaut type). migraine with visual aura must be considered as a differential diagnosis in childhood and adolescents with occipital epilepsy without motor phenomena. objective: the goal of our paper is to report the case a 16-year-old female, with normal psychomotor development, that during the lunch time presented an event characterized by the vision of multiple colored spots which were moving horizontally and vertically and also in circles through the visual field. minutes after the visual event, the patient referred to a severe diffuse throbbing headache with frontal predominance. during the clinical investigation was submitted to a video-electroencephalogram exam for 12 hours with, reveling occipital sharp-waves discharges in occipital right region as well as in occipital left region. conclusion: we reported of such classic type of epileptic syndrome in a patient in the unusual age of onset, the end of adolescence, considering the differential diagnosis with migraine with visual aura.
Metabolic Changes in Occipital Lobe Epilepsy with Automatisms  [PDF]
Chong H. Wong,Andrew F. Bleasel
Frontiers in Neurology , 2014, DOI: 10.3389/fneur.2014.00135
Abstract: Purpose: Some studies suggest that the pattern of glucose hypometabolism relates not only to the ictal-onset zone but also reflects seizure propagation. We investigated metabolic changes in patients with occipital lobe epilepsy (OLE) that may reflect propagation of ictal discharge during seizures with automatisms.

Abstract: is is reported that epilepsy of childhood with occipital paroxysms is an epileptic syndrome that is well defined. it is included in the group of related idiopathic epilepsies with localization. seizures habitually begin with visual symptoms, which are ocassionally followed by hemiclonic, complex partial, and generalized tonicclonic seizures. the interictal eeg shows spike-wave complexes of occipital and temporal posterior localization that are suppressed by eye opening. a patient aged 8 in whom the clinical and electroencephalographic criteria of epilepsy of childhood with occipital paroxysms are present is studied in this paper. emphasis is made on the apparently benign evolution of this syndrome.

Abstract: background: epileptic syndromes with absence seizures (as) possess unique clinical and electroencephalographic (eeg) characteristics. in typical or atypical as, ictal phenomenology may include various characteristics. vídeo-eeg monitoring enables findings to be correlated with ictal phenomenology. objective: to evaluate the different as in a cohort of patients with drug-resistant epilepsy (dre) based on the international league against epilepsy (ilae)'s 2006 classification, to correlate with ictal phenomenology recorded and to apply the panayiotopoulos criteria. method: this study included patients with criteria of as followed up at the epilepsy clinic. a dual, cross-sectional cohort study was carried out between 2005 and 2008. patients receiving care in the epilepsy program of the hucff-ufrj, who had been investigated by video-eeg and who presented clinical and eeg criteria for absence seizures, typical or atypical, according to the criteria defined by the ilae, were included in the study, independent of age onset, the review of clinical history, age onset, family history, epilepsy onset and evolution, seizures phenomenology, antiepileptic drugs response and neuroimaging studies were used to classify the patients among the different epileptic syndrome associated to absence seizures. results: typical absences were more frequent (71.4%) than atypical absences. cases of juvenile absence epilepsy were the most frequent (19%) in this series, followed by childhood absence epilepsy (14.4%) and juvenile myoclonic epilepsy (4.8%). in 14 patients (66.67%), diagnosis was modified from focal epilepsy to primary generalized epilepsy. clinical and eeg diagnosis of absence epilepsy resulted in a dramatic improvement in the control of seizures following modification of diagnosis and indication of an appropriate antiepileptic drug. conclusion: our results show that typical as are more frequent than atypical. as was successfully defined in 10 patients following application of panayi

Abstract: occipital intermittent rhythmic delta activity (oirda) is considered good prognostic factor in typical absences (ta). we report electroclinical evolution in 14 patients with ta and oirda, which performed video-eeg. seven patients were female; 9 had childhood absence epilepsy and the others did not present electroclinical characteristics for syndromic classification according to ilae's classification (1989). pyknolepsy was referred to in 13; ta was the only seizure type in 13; one had generalized tonic-clonic seizures (gtcs) and three had myoclonic jerks during ta. vpa monotherapy controlled seizures in 11, divpa and esm, in one each. after seizure control eeg normalized in 10 while in three, spike-wave complexes (swc) persisted, accompanied by oirda in one. finally in another, seizures were not controlled and swc and oirda persisted. in conclusion, we observed in this series of ta and oirda with onset before 10 years, pyknolepsy as common finding and few gtcs. vpa controlled seizures in most cases and eeg normalized in 76.92%. we suggest that oirda could be considered good prognostic factor in ta associated with swc and of epileptiform nature leading to appropriate investigation.
