    ABSTRACT: To evaluate epileptic children with occipital lobe epilepsy (OLE) in the light of the characteristics of Panayiotopoulos syndrome and late-onset occipital lobe epilepsy of Gastaut (OLE-G). Patients were categorized into six groups: primary OLE with autonomic symptoms (Panayiotopoulos syndrome), primary OLE with visual symptoms (OLE-G), secondary OLE with autonomic symptoms (P-type sOLE), secondary OLE with visual symptoms (G-type sOLE), and non-categorized primary OLE and non-categorized secondary OLE according to characteristic ictal symptoms of both Panayiotopoulos syndrome and OLE-G, as well as aetiology (primary or secondary). Patients were compared with regards to seizure symptoms, aetiology, cranial imaging, EEG, treatment and outcome. Of 108 patients with OLE (6.4±3.9 years of age), 60 patients constituted primary groups (32 with Panayiotopoulos syndrome, 11 with OLE-G, and 17 with non-categorized primary OLE); the other 48 patients constituted secondary groups (eight with P-type sOLE, three with G-type sOLE, and 37 with non-categorized sOLE). Epileptiform activity was restricted to the occipital area in half of the patients. Generalized epileptiform activity was observed in three patients, including a patient with Panayiotopoulos syndrome (PS). Only one patient had refractory epilepsy in the primary groups while such patients made up 29% in the secondary groups. In OLE, typical autonomic or visual ictal symptoms of Panayiotopoulos syndrome and OLE-G do not necessarily indicate primary (i.e. genetic or idiopathic) aetiology. Moreover, primary OLE may not present with these symptoms. Since there are many patients with OLE who do not exhibit the characteristics of Panayiotopoulos syndrome or OLE-G, additional definitions and terminology appear to be necessary to differentiate between such patients in both clinical practice and studies.

    ABSTRACT: Performing epilepsy surgery on children with non-lesional brain MRI often results in large lobar or multilobar resections. The aim of this study was to determine if smaller resections result in a comparable rate of seizure freedom. We reviewed 25 children who had undergone focal corticectomies restricted to one aspect of a single lobe or the insula at our institution within a 5.5-year period. Data collected in the comprehensive non-invasive pre-surgical evaluation (including scalp video-EEG, volumetric MRI, functional MRI, EEG source localization, and SPECT and PET), as well as from invasive recordings performed in each patient, was reviewed. Data from each functional modality was identified as convergent or divergent with the epileptogenic zone using image coregistration. Specific biomarkers (from extra-operative and invasive testing) previously indicated to be indicative of focal epileptogenicity were used to further tailor each resection to an epileptogenic epicentre. Tissue pathology and postoperative outcomes were obtained from all 25 patients. Two years postoperatively, 15/25 (60%) children were seizure-free, three (12%) experienced >90% reduction in seizure frequency, two (8%) had a 50-90% reduction in seizure frequency, and the remaining five (20%) had no change in seizure burden. There was no significant difference in outcome based on numerous pre- and postoperative factors including location of resection, the number of preoperative functional tests providing convergent data, and tissue pathology. In MRI-negative children with focal epilepsy, an epileptogenic epicentre within a larger epileptogenic zone can be identified when specific biomarkers are recognized on non-invasive and invasive testing. When such children undergo resection of a small, well-defined epileptogenic epicentre, favourable outcomes can be achieved.

    ABSTRACT: Signs indicating the end of a focal seizure with loss of awareness and/or responsiveness but without progression to focal or generalized motor symptoms are poorly defined and can be difficult to determine. Not recognizing the transition from ictal to postictal behaviour can affect seizure reporting accuracy by family members and may lead to delayed or a lack of examination during EEG monitoring, erroneous seizure localization and inadequate medical intervention for prolonged seizure duration. Our epilepsy monitoring unit database was searched for focal seizures without secondary generalization for the period from 2007 to 2011. The first focal seizure in a patient with loss of awareness and/or responsiveness and/or behavioural arrest, with or without automatisms, was included. Seizures without objective symptoms or inadequate video-EEG quality were excluded. A total of 67 patients were included, with an average age of 41.7 years. Thirty-six of the patients had seizures from the left hemisphere and 29 from the right. All patients showed an abrupt change in motor activity and resumed contact with the environment as a sign of clinical seizure ending. Specific ending signs (nose wiping, coughing, sighing, throat clearing, or laughter) were seen in 23 of 47 of temporal lobe seizures and 7 of 20 extra-temporal seizures. Seizure ending signs are often subtle and the most common finding is a sudden change in motor activity and resumption of contact with the environment. More distinct signs, such as nose wiping, coughing or throat clearing, are not specific to temporal lobe onset. A higher proportion of seizures during sleep went unexamined, compared to those during wakefulness. This demonstrates that seizure semiology can be very subtle and arousals from sleep during monitoring should alert staff. Patient accounts of seizure frequency appear to be unreliable and witness reports need to be taken into account. [Published with video sequences].

    ABSTRACT: Brief rhythmic discharges (BRDs) are paroxysms of rhythmic electrographic activity with an amplitude of >2 μV and a duration of <10 seconds. Although BRDs are reported in neonates, this electrographic activity contrasts the accepted definition of neonatal seizures (duration of >10 seconds). BRDs are associated with background EEG abnormalities as well as increased morbidity and mortality (Oliveira et al., 2000, Nagarajan et al., 2011), and appear to be more closely related to formal neonatal seizures than post-neonatal epilepsy (Nagarajan et al., 2011). Most neonatal units are restricted to one-hour recordings, and if BRDs are observed without any accompanying electrographic seizures, then the neonate should be regarded as being at high risk of seizures and repeat recordings should be considered.

    ABSTRACT: About 25% of seizures in the neonatal period have causes other than asphyxia, ischaemia or intracranial bleeding. Among these are primary genetic epileptic encephalopathies with sometimes poor prognosis and high mortality. In addition, some forms of neonatal infant seizures are due to inborn errors of metabolism that do not respond to common AEDs, but are amenable to specific treatment. In this situation, early recognition can allow seizure control and will prevent neurological deterioration and long-term sequelae. We review the group of inborn errors of metabolism that lead to newborn/infant seizures and epilepsy, of which the treatment with cofactors is very different to that used in typical epilepsy management.

    ABSTRACT: To date, there is limited understanding of the role of the precuneus. fMRI studies have suggested its involvement in a wide spectrum of highly integrated tasks, including spatially-guided behaviour, visuo-spatial imagery, and consciousness. We present a patient with intractable parietal lobe epilepsy arising from a lesion localized to the right precuneus. Two seizure types with distinct semiologies were captured on video-EEG monitoring. The first type consisted of an urge described as a "feeling of wanting to move". On video analysis, the patient is seen to turn his head and body to his left. He remains conscious, he is able to answer questions and when asked, he can look to his right. This seizure was associated with an ictal pattern localized to the right parieto-occipital region. The second seizure type consisted of reading-induced visual distortion with macropsia and micropsia. Interictally, intermittent rhythmic slowing and spikes were seen and localized to the parietal midline and the right parieto-occipital regions. Our patient's seizures are positive phenomena of the right precuneus and its related processing network. They represent unique seizure semiologies that offer further insight into the role of the precuneus in spatial awareness, visuo-spatial processing and consciousness.

    ABSTRACT: We report a 4-year-old boy with generalized seizures with abrupt falling and unresponsive staring provoked by somatosensory stimuli of the face. Ictal manifestation comprised a sudden fall immediately after wiping the face, followed by unresponsive staring for around 10 seconds, during which time the video-EEG recorded paroxysmal 3-Hz diffuse spike-wave complexes, which were followed by high-voltage 3.5 to 4-Hz delta wave discharges, predominantly appearing in the bilateral frontal areas. Seizures were not controlled by clonazepam, valproate or levetiracetam, but were successfully treated with lamotrigine added to valproate. This type of generalized reflex seizure has so far not been reported in the literature. [Published with video sequence].

    ABSTRACT: Rasmussen's encephalitis is a rare, chronic inflammatory disorder of unknown cause, characterised by drug-resistant focal epilepsy that may rarely present in adolescence or adulthood. We present a case of Rasmussen's encephalitis with prominent recurrent fluctuation in symptoms and well-documented fluctuating changes on MRI, adding to the spectrum of diversity of Rasmussen's encephalitis.

    ABSTRACT: It is well known that both falls and epileptic seizures are very frequent and harmful in the elderly. Moreover, although seizures may cause falls, their relationship is poorly documented in this population. We report four women (mean age: 84.5 years) who presented falls with: late-onset focal seizures of possible parietal (Case 1) or frontal localisation (Case 2), early onset with late aggravation of juvenile myoclonic epilepsy (Case 3), and generalised situation-related myoclonic seizures (Case 4). Falls were presumably associated with tonic posturing of left (Case 1) or right (Case 2) hemibody, to bilateral and massive myoclonic jerks (Cases 3 and 4) with a loss of consciousness (Case 3). The diagnosis of seizures was difficult and routine EEG was unremarkable in Cases 1 and 2, requiring video-EEG monitoring to capture the clinical events. Adequate treatment offered recovery from seizures and falls in all patients. Other mechanisms of seizure-induced falls in older patients and their management are discussed. In conclusion, falls may be caused by different seizure types and appear to be underestimated due to difficulties in seizure diagnosis in the elderly. Recognizing falls related to seizures is important in geriatric practice, as it facilitates adequate management.
