Benign Epilepsy of Childhood With Rolandic Spikes: Typical and Atypical Variants
Pediatric Neurology, 2007
Clinical course and outcome were compared for 126 children with typical and atypical features of benign epilepsy of childhood with rolandic spikes (BECRS). A retrospective case series design was used, in the setting of a tertiary-care pediatric hospital. The subjects were subdivided into two groups, based on clinical presentation. Group A comprised children with typical features of BECRS (n ؍ 66; 52%) and Group B, those with atypical features (n ؍ 60; 48%). Patients' charts were reviewed for demographic data, family history, comorbid conditions, atypical clinical features, antiepileptic drugs, and outcome data. Comorbid disorders (e.g., attention deficit hyperactivity disorder, behavioral problems) were slightly more frequent in the atypical group. Overall, there was no difference between the time to become seizure free between the groups: by two years, 41 of 66 in Group A (62%) and 44 of 60 in Group B (71%) were controlled on medication and seizure free. Twenty of the 126 children (16%) required trial of a second anti-epileptic drug: 7 in Group A and 13 in Group B. Resolution of the epilepsy occurred in about the same length of time in both groups (but at different ages, consistent with different age of onset). Both groups had similar longterm outcome.
Rolandic Epilepsy: Self-Limited Epilepsy with Centrotemporal Spikes
Epilepsy - Update on Classification, Etiologies, Instrumental Diagnosis and Treatment, 2021
Childhood epilepsy with centrotemporal spikes, had been previously considered as benign childhood epilepsy. According to the new classification proposed by Sheffer I. and colleagues the term “benign” has been changed to “self-limited”. Many studies reported that BECTS may cause transient or long lasting cognitive and behavioral disturbances. Rolandic epilepsy is the most frequent among the childhood focal epilepsy and may account for about 15–25% of all epileptic syndromes diagnosed between the ages of 5 to 15 years. The incidence range changes between 7.1–21 per 100000 in population younger than 15 years with male predominance. The age of onset in 90% of cases between 1 and 10 years with peak around 6–7 years. Seizures mainly occur during a night sleep, whereas the probability of awake seizures are less than 10%. The characteristic clinical features are: (1) focal motor seizure with unilateral orofacial tonic or clonic contractions; (2) speech arrest; (3) hypersalivation; (4) senso...

Benign childhood epilepsy with centrotemporal spikes (BCECTS) is an idiopathic focal epilepsy syndrome, the benign characteristics of which are debated; in fact, stable or intermittent specific neuropsychological deficits are frequent and may affect scholastic or adaptive abilities. Cognitive dysfunction may be related to a marked increment of the interictal epileptic discharges in NREM sleep: different degrees of neuropsychological deficits depend on the extent of awake and sleep activity and the predominant discharge localization. The age of onset and duration of atypical sleep EEG patterns may correlate with permanent cognitive impairments. These atypical clinical and EEG evolutions have been reported in the literature as different syndromes that constitute the spectrum of idiopathic rolandic epilepsy. Moreover, a clinical link between BCECTS and early-onset benign childhood occipital epilepsy has been demonstrated. According to the neurobiological approach, the spectrum of Idiopathic Rolandic Epilepsy is based on an age-dependent, idiopathic predisposition to focal seizures and sharp-wave discharges, as an expression of nonlesional cortical excitability. The involvement of a given area of the cerebral cortex may depend on the brain maturational stage.
A Case Report on Rolandic Epilepsy
Pondicherry Journal of Nursing, 2021
Benign focal epilepsy of childhood is an entity that includes characteristic clinical and electroencephalographic manifestations. An epileptic seizure is a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain. Epilepsy is a disorder of the brain characterized by an enduring predisposition to generate epileptic seizures and by the neurobiological, cognitive, psychological, and social consequences of this condition. Here we report a case of Rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes (BCECTS), which is the most typical epilepsy, and the child presented with typical symptoms of active seizures in the form of uprolling of the eyes and jerky movements of the upper limbs.
Are there generalised spike waves and typical absences in benign rolandic epilepsy?
Brain and Development, 1999
Generalised 3 Hz spike wave (SW) discharges with or without absences have been described in children with benign epilepsy with centrotemporal spikes (BECTS), leading to speculations about a continuum between childhood absence epilepsy (CAE) and BECTS. We thus decided to evaluate the prevalence of absence seizures (AS) and generalised 3 Hz SW in patients with BECTS. All patients with BECTS ®rst referred since 1986 have been identi®ed prospectively. Their medical and electroencephalograph (EEG) records were analysed retrospectively, in the search for AS and generalised SW discharges. Over a period of 11 years, we found typical rolandic spikes in 66 newly referred patients; 64 had seizures typical for the condition (18 female, 46 male), two were asymptomatic and were not further analysed. All had routine waking EEG recordings, and 49 children (76%) had at least one sleep EEG. AS or classical generalised 3 Hz SW were never recorded from history or EEG data, respectively. However, 17 patients had some diffuse SW discharges, lasting 1±5 s, which appeared as grossly symmetrical in only seven children, with a clearly asymmetrical aspect in the others. Among these seven patients, the discharges were only seen on awakening in one, both during waking and nREM sleep stage I or II in one and only during nREM sleep stage I or II in ®ve. They were apparently subclinical in all. We thus found neither AS nor classical 3 Hz SW discharges among 64 consecutive patients with BECTS. Brief bursts of bilateral abnormalities occur in about 25% of the cases, mostly with sleepiness. Such ®ndings do not substantiate the existence of a continuum between CAE and BECTS. q
Benign rolandic epilepsy and generalized paroxysms: A study of 13 patients
Seizure, 2018
To present a retrospective study of 13 children with benign epilepsy with centrotemporal spikes (BECTS), also known as benign rolandic epilepsy (BRE), associated with generalized spikes and waves as the only EEG manifestation at onset. Charts of children with typical clinical criteria of BRE electroclinically followed-up between February 2000 and February 2015 were reviewed. Among 309 patients who met the electroclinical criteria of BRE, we identified 13 children who presented with the typical clinical manifestations but who, on the EEG, only had generalized paroxysms at onset that continued along the course of the syndrome. Generalized spike-and-wave discharges were observed in all patients when awake and during sleep (100%). During the evolution no particular electroclinical pattern was observed. The patients responded well to antiepileptic drugs, such as valproic acid and levetiracetam. Outcome was good in all patients. We found evidence that patients with BRE may have generalize...
Electroclinical significance of rolandic spikes and dipoles in neurodevelopmentally normal children
Electroencephalography and Clinical Neurophysiology, 1995
"Centrotemporal" (rolandic) spikes are elemental to the diagnosis of benign rolandic epilepsy (BRE) and may reveal a characteristic dipole distribution. Yet, not all children with rolandic spikes present with clinical seizures. Using additional scalp coverage according to the 10-10 electrode system, we attempted to correlate 2 specific spike features: (a) dipole fields, and (b) exact location of maximum negativity, with the presence or absence of clinical seizures in 42 neurodeveiopmentally normal children with rolandic (central) spikes. Thirty-three (79%) presented with seizures. Seventeen of 21 children revealing dipoles (81%) and 16 of 21 patients without dipoles (74%) had seizures. Children with high central (C3/C4) foci were just as likely to present with seizures (10 of 15, 67%) as were those with low central (C5/C6) foci (23 of 27, 85%) (P > 0.10). The majority of our study subjects (27 of 42, 64%) revealed maximum negativity in the low central region (C5/C6), and the dipole feature was as likely to be associated with high central foci (7 of 15, 47%) as with low central loci (14 of 27, 52%). Although rolandic spikes are a reliable indicator of potential epileptogenicity, neither their exact location nor dipolar distribution help to further define the population with clinical seizures.
