Clinical features associated with epilepsy occurrence, resolution, and drug resistance in children with cerebral palsy: A population-based study. Dev Med Child Neurol 2024; 66:793-803. [PMID: 38059324 DOI: 10.1111/dmcn.15807] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 10/08/2023] [Accepted: 10/17/2023] [Indexed: 12/08/2023]
Abstract
AIM To investigate clinicoradiological features associated with epilepsy, its resolution, and drug resistance in children with cerebral palsy (CP). METHOD Data were gathered from the New South Wales/Australian Capital Territory CP Register, encompassing children with CP born between 2003 and 2015 (n = 1916). Clinical features and the severity of impairments were compared among three groups: children with current epilepsy (n = 604), those with resolved epilepsy by age 5 years (n = 109), and those without epilepsy (n = 1203). Additionally, a subset of the registry cohort attending Children's Hospital Westmead (n = 256) was analysed to compare epilepsy and treatment characteristics between drug-responsive (n = 83) and drug-resistant groups (n = 147) using logistic regression and hierarchical cluster analysis. RESULTS Manual Ability Classification System levels IV and V, intellectual impairment, and vision impairment were found to be associated with epilepsy in children with CP on multivariable analysis (p < 0.01). Moderate to severe intellectual impairment and bilateral spastic CP were independent positive and negative predictors of epilepsy persistence at the age of 5 years respectively (p < 0.05). Microcephaly and multiple seizure types were predictors of drug-resistant epilepsy (area under the receiver operating characteristic curve of 0.83; 95% confidence interval 0.77-0.9). Children with a known genetic cause (14%) and CP epilepsy surgery group (4.3%) formed specific clinical subgroups in CP epilepsy. INTERPRETATION Our study highlights important clinical associations of epilepsy, its resolution, and treatment response in children with CP, providing valuable knowledge to aid in counselling families and identifying distinct prognostic groups for effective medical surveillance and optimal treatment. WHAT THIS PAPER ADDS Severe motor and non-motor impairments in cerebral palsy (CP) increase epilepsy risk. Epilepsy more likely resolves in bilateral spastic and milder CP impairments. Epilepsy in CP often manifests at an early age with multiple seizure types and high drug resistance. Children with a known genetic cause and CP epilepsy surgery group represent distinct clinical subgroups.

Abstract
OBJECTIVES In this study, we examined whether epilepsy and drug-resistant epilepsy are associated with neuroimaging findings in children with cerebral palsy (CP). METHODS Magnetic resonance imaging classification system (MRICS) proposed by Surveillance of Cerebral Palsy in Europe (SCPE) was used for classification of different MRI patterns in patients with cerebral palsy. We reviewed the brain MRI scans and medical records of children with CP who were followed-up in our clinic between 2019 and 2023. Patients were divided into three categories: CP without epilepsy, CP with controlled epilepsy and CP with DRE. MRI patterns were grouped as maldevelopments, predominant white matter injury, predominant gray matter injury, miscellaneous (delayed myelination, cerebral atrophy, cerebellar atrophy, brainstem lesions and calcifications, lesions that were not classified under any other group) and normal according to MRICS of the SCPE. RESULTS There were 325 CP patients. The most common MRI patterns were predominant white matter injury (47.6%) and gray matter injury (23.8%). There was a 1.5-fold reduction in the risk of epilepsy in patients with predominant white matter injury (OR = 1.54, 95% CI 1.23-1.94). In contrast, children in the miscellaneous group had significantly higher risks of epilepsy (p < 0.001), and we were able to determine that miscellaneous findings increased the risk by 1.8 times (OR = 1.77, 95% CI 1.47-2.12). CONCLUSION In conclusion, more than half of the children with CP had epilepsy, 40.7% of whom had DRE. On MRI, miscellaneous findings may indicate a poor prognosis for epilepsy, while predominant white matter injury may indicate a good outcome. Children with CP, especially those with miscellaneous findings on MRI, should be closely monitored for epilepsy development.

Abstract
INTRODUCTION Epilepsy is found in 10-60% of individuals with cerebral palsy (CP) and 5.5-35% with intellectual disability (ID). However, little is known about the long-term evolution of epilepsy among adults. The aim of the study is to describe the factors associated with epilepsy and its outcome in a population of adults with CP or ID. METHODS This retrospective study reviewed the medical records of 306 individuals with CP/ID. All individuals underwent neurological, psychiatric, and neuropsychological follow-ups. RESULTS In the cohort, 72.5% of the individuals had a CP diagnosis, with a mean age of 36.4 years (IQR 24.0-46.0). Epilepsy was present in 55.6% of the individuals and was associated with CP (p < 0.01), spastic subtype (p < 0.01), a higher degree of ID (p < 0.01), hemorrhagic and congenital malformation etiologies (p 0.011), abnormal neuroimaging (p < 0.01), and worse scores on motor and communication scales (p < 0.01). Drug-resistant epilepsy (DRE) (22.4%) was associated with higher scores on motor scales (p < 0.01). Additionally, 42.3% of the individuals who attempted antiseizure medication (ASM) withdrawal experienced recurrence, which was associated with epileptic activity on the electroencephalogram (EEG) (p 0.004). CONCLUSIONS Epilepsy is a common comorbidity in adults with CP or ID and is associated with greater brain damage and a more severe phenotype. Seizure recurrence after ASM withdrawal occurred in half of the individuals and was associated with epileptic activity on the EEG.

Abstract
Objective To study the worldwide prevalence and associated factors of epilepsy in children and adolescents with Cerebral Palsy (CP) and to analyze the differences between various subgroups. Method We identified all potential studies on the prevalence of epilepsy in children and adolescents with CP from PubMed, Web of Science, and Embase. The search time was from the establishment of the database to November 2022. Randomized effects meta-analysis models were used to calculate the prevalence of epilepsy in CP. Subgroup analysis and meta-regression were utilized to further explore heterogeneity between articles and prevalence disparities between subgroups. The funnel plot and Egger's test were used to investigate potential publication bias. Results Seventy-two articles, comprising 53,969 children and adolescents with CP, were included in this study. The results indicated a total epilepsy prevalence of 38.0% (95% CI: 34.8%-41.2%) in CP. The prevalence of epilepsy was 46.4% (95% CI: 41.4%-51.5%) in clinical sample-based studies and 31.6% (95% CI: 28.7%-34.5%) in population-based studies. Meta-regression demonstrated that the sample source, neonatal seizure, family history of epilepsy, EEG or cranial imaging abnormalities, intellectual/cognitive impairment, and topographical types of CP were heterogeneous contributors to the epilepsy prevalence in CP. Conclusion Approximately one-third of children and adolescents with CP have epilepsy, and the sample source can significantly impact the total prevalence of epilepsy. Neonatal seizures, family history of epilepsy, EEG abnormalities, cranial imaging abnormalities, severe intellectual disability, and quadriplegia may be contributing factors to epilepsy comorbid in CP. Further study is required to verify the strength of these associations with epilepsy. This study aids in identifying the clinical characteristics of young people with CP at risk of developing epilepsy, which may assist clinicians in the early prevention and diagnosis of epilepsy within this population.Systematic Review Registration: https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=367766, identifier CRD42022367766.

Characteristics and Challenges of Epilepsy in Children with Cerebral Palsy-A Population-Based Study. J Clin Med 2023; 12:jcm12010346. [PMID: 36615146 PMCID: PMC9821172 DOI: 10.3390/jcm12010346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 12/21/2022] [Accepted: 12/29/2022] [Indexed: 01/03/2023] Open
Abstract
The aim of this population-based study was to describe the prevalence and characteristics of epilepsy in children with cerebral palsy (CP), focusing on antiseizure medication (ASM) and seizure outcome. Findings were related to CP type, gross motor function and associated impairments. Data on all 140 children with CP born in 2003-2006 were taken from the CP register of Western Sweden. Medical records were reviewed at ages 9-12 and 13-16 years. In total 43% had a diagnosis of epilepsy. Epilepsy was more common in children with dyskinetic CP, who more often had a history of infantile spasms, continuous spike-and-wave during sleep and status epilepticus. Neonatal seizures, severe intellectual disability, severe motor disability and autism were associated with a higher risk of epilepsy. Many children were on polytherapy, and valproate was frequently used, even in girls. At age 13-16 years, 45% of the children with epilepsy were seizure free for at least one year. Onset after 2 years of age, female sex and white matter injury were associated with good seizure outcome. Despite the risk of relapse, reduction or discontinuation of ASM could be an option in selected cases. It is important to optimize ASM and to consider the possibility of epilepsy surgery.

Abstract
OBJECTIVE We aimed to evaluate early-life epilepsy incidence, seizure types, severity, risk factors, and treatments among survivors of acute neonatal seizures. METHODS Neonates with acute symptomatic seizures born 7/2015-3/2018 were prospectively enrolled at nine Neonatal Seizure Registry sites. One-hour EEG was recorded at age three months. Post-neonatal epilepsy and functional development (Warner Initial Developmental Evaluation of Adaptive and Functional Skills - WIDEA-FS) were assessed. Cox regression was used to assess epilepsy-free survival. RESULTS Among 282 infants, 37 (13%) had post-neonatal epilepsy by 24-months [median age of onset 7-months (IQR 3-14)]. Among those with post-neonatal epilepsy, 13/37 (35%) had infantile spasms and 12/37 (32%) had drug-resistant epilepsy. Most children with post-neonatal epilepsy had abnormal neurodevelopment at 24-months (WIDEA-FS >2SD below normal population mean for 81% of children with epilepsy vs 27% without epilepsy, RR 7.9, 95% CI 3.6-17.3). Infants with severely abnormal neonatal EEG background patterns were more likely to develop epilepsy than those with mild/moderate abnormalities (HR 3.7, 95% CI 1.9-5.9). Neonatal EEG with ≥3 days of seizures also predicted hazard of epilepsy (HR 2.9, 95% CI 1.4-5.9). In an adjusted model, days of neonatal EEG-confirmed seizures (HR 1.4 per day, 95% CI 1.2-1.6) and abnormal discharge examination (HR 3.9, 95% CI 1.9-7.8) were independently associated with time to epilepsy onset. Abnormal (vs. normal) three-month EEG was not associated with epilepsy. SIGNIFICANCE In this multicenter study, only 13% of infants with acute symptomatic neonatal seizures developed post-neonatal epilepsy by age 24-months. However, there was a high risk of severe neurodevelopmental impairment and drug-resistant seizures among children with post-neonatal epilepsy. Days of EEG-confirmed neonatal seizures was a potentially modifiable epilepsy risk factor. An EEG at three months was not clinically useful for predicting epilepsy. These practice changing findings have implications for family counseling, clinical follow-up planning, and future research to prevent post-neonatal epilepsy.

Epilepsy and drug-resistant epilepsy in children with cerebral palsy: A retrospective observational study. Epilepsy Behav 2020; 112:107357. [PMID: 32858364 DOI: 10.1016/j.yebeh.2020.107357] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 07/14/2020] [Accepted: 07/15/2020] [Indexed: 11/22/2022]
Abstract
PURPOSE The objective of this study was to determine risk factors for epilepsy and drug-resistant epilepsy (DRE) development in children with cerebral palsy. METHOD Two hundred twenty-nine patients presenting to the pediatric neurology clinic and diagnosed as having cerebral palsy between November 2016 and November 2019 were included in the study. Medical histories and clinical, laboratory, and radiological findings were examined retrospectively from patient records in the hospital data system. RESULTS Girls represented 103 patients (45%) and boys 126 (55%). The patients' mean age was 8.39 ± 4.54 years. Epileptic seizures were present in 120 (52.4%) patients and drug-resistant seizures in 64 (27.9%). The risk of epilepsy was significantly higher in patients with motor or speech impairment, with hearing impairment, or undergoing first seizure in the neonatal period. We also observed a higher risk of epilepsy in patients with psychiatric comorbidity, particularly autism spectrum disorder. The risk of epilepsy was also higher in patients with microcephaly or quadriplegic cerebral palsy and in patients with focal and generalized epileptiform abnormality on electroencephalograms (EEGs). However, no significant difference was identified when all these factors were evaluated in terms of the risk of developing DRE. CONCLUSION Patients with cerebral palsy have high comorbid epilepsy rates. We think that the risk of epilepsy may be higher in patients undergoing first seizure in the neonatal period, with microcephaly, with quadriplegic type cerebral palsy, and with additional psychiatric comorbidity. The rate of DRE development was very low in patients with normal EEG findings or with only background rhythm abnormalities on first EEGs during neonatal seizures. This may be regarded as a good prognostic factor for nondevelopment of DRE.

Abstract
Cerebral palsy (CP) is a set of etiologically diverse symptoms that change with the child's age. It is one of the most frequent causes of motor disability in children. CP occurs at a frequency of 1.5 to 3.0 per 1000 live-born children. CP often coexists with epilepsy, which is drug-resistant in a high number of cases. The aim of the present study was to analyze the associations between preconception, prenatal, perinatal, neonatal, and infancy risk factors for epilepsy in a group of pediatric patients with CP. We retrospectively analyzed 181 children with CP (aged 4-17 years at diagnosis), hospitalized at the Department of Pediatrics and Developmental Age Neurology in Katowice in the years 2008-2016. Division into particular types of CP was based on Ingram's classification. Data were analyzed using STATISTICA 13.0 (STATSOFT; Statistica, Tulsa, OK, USA). Epilepsy was diagnosed in 102 children (56.35%), of whom 44 (43%) had drug-resistant epilepsy; only in 15 cases (14.71%) was epilepsy susceptible to treatment. The incidence of epilepsy varied between the types of CP. It occurred significantly more often in children with tetraplegia (75%), ataxic form (83%), and mixed form (80%) in comparison to diplegia (32%) and hemiplegia (38%). Maternal hypertension was found to be a risk factor for epilepsy in CP patients (OR = 12.46, p < 0.001) as well as for drug-resistant epilepsy (the odds ratio (OR) = 9.86, p = 0.040). Delivery by cesarean section increased the risk of epilepsy in the CP patients over two-fold (OR = 2.17, p = 0.012). We observed also that neonatal convulsions significantly increased the risk for epilepsy (OR = 3.04, p = 0.011) as well as drug-resistant epilepsy (OR = 4.02, p = 0.002). In conclusion, maternal hypertension, neonatal convulsions, and delivery by cesarean section were the most important factors increasing the risk of epilepsy as well as drug-resistant epilepsy in the analyzed group of patients with CP.

Abstract
Epilepsy is estimated to exist in approximately 40% of individuals with cerebral palsy; however, the specific features that make it drug resistant are not well defined. The main aim of this study was to determine the clinical risk factors that could predict drug-resistant epilepsy, in children with cerebral palsy. The study was performed via a retrospective chart review, analyzing clinical parameters of 118 children with cerebral palsy with either drug-resistant epilepsy or controlled epilepsy, between the years 2013 and 2018. We established a predictive model for drug-resistant epilepsy in children with cerebral palsy that is simple to apply in clinical settings and composed of the additive effect of a low Apgar score at 5 minutes, neonatal seizures, focal-onset epilepsy, and focal slowing on electroencephalogram (EEG; area under the receiver operating characteristic of 0.840). Early prediction of drug-resistant epilepsy may benefit to achieve better seizure control in children with cerebral palsy.

Abstract
Cerebral palsy (CP) is one of the most frequent causes of motor disability in children. According to the up-to-date definition, CP is a group of permanent disorders of the development of movement and posture, causing activity limitations that are attributed to non-progressive disturbances that occurred in the developing foetal or infant brain. The CP definition has evolved over time; the problem is aetiologically and clinically very heterogeneous. According to European data, the average frequency of CP is 2.08 per 1000 live births, but in the group of children born with a body weight below 1500 g, the frequency is 70 times higher when compared with the group of children with a body weight over 2500 g at birth. The risk factors for CP can be divided into pre-conception, prenatal, perinatal and postnatal ones. CP commonly co-exists with epilepsy, in particular drug-resistant epilepsy, but also with mental retardation, visual and hearing impairment, as well as feeding and behavioral disorders. The degree of motor problem varies from mild to very severe making the child totally dependent on caregivers. Cerebral palsy is divided into forms depending on the type of motor disorders which dominate the clinical presentation; the traditional classifications by Ingram and Hagberg have now been replaced by the Surveillance of Cerebral Palsy in Europe classification which divides CP into spastic, dyskinetic and ataxic forms. Although cerebral palsy is a clinical diagnosis, modern diagnostic imaging provides information that allows the division of the results of magnetic resonance imaging in children with cerebral palsy into five groups according to the magnetic resonance imaging classification system. Just as the clinical presentation and the factors predisposing for CP are very diverse, treatment is also a very complex problem. Modern treatment of spasticity includes both botulinum toxin therapies and surgical techniques, eg, rhizotomy. The authors present current views on definitions, risk factors, diagnostics and treatment of CP as well as comorbid problems, eg, drug-resistant epilepsy.

Abstract
Seizures are an important sign of neurologic dysfunction in neonates, and they most often represent acute brain injury such as hypoxic-ischemic encephalopathy, stroke, or intracranial hemorrhage (acute symptomatic seizures). Clinical identification of seizures is not reliable since seizures in neonates often do not have an apparent clinical correlate; therefore, electroencephalography should be used to accurately diagnose and manage neonatal seizures. Seizures are refractory to initial loading doses of standard medications in >50% of cases. Since seizures are commonly associated with adverse acute and long-term outcomes, and the seizures themselves may result in additional brain injury, it is important to quickly recognize, diagnose, and treat seizures in neonates. Local practice pathways may optimize efficiency in assessment and treatment for affected newborns. Herein, we review the etiology, methods of diagnosis, treatment, and current knowledge gaps for neonatal seizures.

Abstract
AIM To assess the long-term natural course and prognosis of epilepsy in patients with cerebral palsy (CP). METHOD We retrospectively collected data for 72 patients (36 males, 36 females) with CP who had epilepsy who visited our institutions between 1980 and 2015. The data from medical records, electroencephalography (EEG), and neuroimaging findings were reviewed. Time-to-event statistical analyses were performed to analyse the remission outcome and the Cox regression model was used for multivariate analyses. RESULTS Median age at onset of epilepsy was 2 years 0 months, and 17 years 0 months at the latest follow-up. In total, 34 patients (47%, 0.043 per person-year) achieved seizure remission at a median age of 11 years 0 months. Favourable factors for seizure remission included older age, motor disability being able to roll over/crawl but not able to sit, intellectual disability with an IQ between 36 and 70, normal findings on neuroimaging, and CP type other than spastic quadriplegia. In multivariate analysis, spastic quadriplegia was found to be associated with continued seizure activity. Antiepileptic drugs could be discontinued without relapse in 10 patients at a median age of 16 years 6 months, occurring 11 years 6 months after the onset of epilepsy. The drugs were terminated if the patient was aged at least 10 years and had perinatal causative aetiology and normalization or amelioration of epileptiform discharges on EEG. INTERPRETATION The remission rate of epilepsy in CP increases up to young adulthood, and termination of antiepileptic drugs can be considered in selected cases at older ages. WHAT THIS PAPER ADDS The remission rate of epilepsy in cerebral palsy increases up to 20 years after onset. In some cases, antiepileptic drugs (AEDs) can be terminated without relapse. Older age, perinatal aetiology, and improvement on electroencephalography are favourable factors for terminating AEDs.

Abstract
OBJECTIVES Epilepsy is one of the most common and important comorbidity among patients with cerebral palsy (CP). The purpose of this study was to determine the risk factors predicting the development of epilepsy considering prenatal, perinatal, and natal characteristics; associated impairments; and cranial imaging findings in our patient population with cerebral palsy at a tertiary center in Istanbul, Turkey. METHODS This retrospective study consisted of 234 children aged between 3 and 18 years of age. Children were divided into two groups as CP patients with epilepsy (126 patients) and CP patients without epilepsy (108 patients). Demographic features and clinical and cranial magnetic resonance imaging (cMRI) findings were compared between the two groups. RESULTS Presence of family history of epilepsy, history of neonatal seizure especially in the first 72 h of life, quadriplegic type of CP, severe degree of gross motor function and fine motor disorders, and moderate to severe mental retardation or psycho-social developmental delay were determined as risk factors for the development of epilepsy in CP patients. Also, an increased risk of epilepsy was detected in term infants and appropriate for gestational age (2500-4000 g) infants. On the other hand, presence of parental consanguinity, being born from a primiparous mother, age of mother at birth, mode of delivery, presence of multiple gestation and labor problems, history of follow-up in neonatal intensive care unit and intubation, and cMRI findings were not significant risk factors for the development of epilepsy in CP. CONCLUSION Predicting epilepsy development by determining the risk factors in patients with CP might be useful because knowing the risk factors could provide close follow-up of these patients for epilepsy.

Abstract
PURPOSE The aim of the present study was to investigate epilepsy patterns and outcomes in patients with cerebral palsy (CP) and identify the variables that determine remission. METHODS This was a retrospective cohort study. We followed 107 CP patients aged 1-16 years with newly diagnosed epilepsy. The patients were categorized according to their remission outcome, uninterrupted freedom of seizure for 2 years or longer, and 4 epilepsy patterns: A) sustained freedom from seizures before 6 months of treatment; B) delayed but sustained seizure freedom; C) relapsing-remitting course; and D) seizure freedom never attained. The variables were analysed for their prognostic relevance to the outcomes RESULTS: A total of 107 patients were included; their mean age at epilepsy diagnosis was 4.2 years (SD 2.5). By the end of the 8-year follow up, 19.6% 26.1%, 31.7%, and 22.4% were in sustained remission, terminal remission, relapse, and no remission respectively. Pattern A was identified in 6.5% of the patients, pattern B in 27.1%, pattern C in 43.9%, and pattern Din 22.4%. Univariate analysis revealed that the type of CP, mobility, and number of seizure types, are among the other factors that significantly affected remission. CONCLUSION A total of 45% of patients with CP and epilepsy achieved remission (with and without antiepileptics) but after a relatively long treatment duration. Remission was affected by patient- and epilepsy-related factors. More studies are required to further evaluate these factors.

Abstract
The first weeks of life are a time of heightened risk for seizures due to age-dependent physiologic features of the developing brain that lead to increased neuronal excitation and decreased inhibition. Usually, seizures in neonates are a symptom of an acute brain injury; seizures are only rarely due to neonatal-onset epilepsy syndromes. Neonatal seizures are harmful to the developing brain; early and accurate diagnosis is critical. For suspected seizures, EEG monitoring should be initiated as soon as is feasible, in order to evaluate for events of concern, screen for subclinical seizures, and assess the EEG background. Amplitude-integrated EEG can provide excellent complementary data, particularly with regard to evolution of background patterns, but has limited sensitivity to detect individual neonatal seizures. An urgent and systematic approach to precise etiologic diagnosis is key for optimal management and estimates of prognosis. Evaluation of the seizure etiology must occur in parallel with initiation of appropriate treatment. It is critical that neonatologists and neurologists develop hospital-specific, consensus-based practice pathways for neonatal seizure evaluation and treatment. Such practice pathways can streamline medical decision making, facilitate rapid medication administration, and potentially decrease seizure burden and optimize outcomes. Herein, the pathophysiology, epidemiology, treatment, and long-term management considerations for neonatal seizures are presented.

Abstract
Acute symptomatic seizures are a common sign of neurological dysfunction and brain injury in neonates and occur in approximately one to three per 1000 live births. Seizures in neonates are usually a sign of underlying brain injury and, as such, are commonly associated with adverse outcomes. Neurological morbidities in survivors often co-occur; epilepsy, cerebral palsy, and intellectual disability often occur together in the most severely affected children. Risk factors for adverse outcome include prematurity, low Apgar scores, low pH on the first day of life, seizure onset <24 or >72 h after birth, abnormal neonatal neurological examination, abnormal neonatal electroencephalographic background, status epilepticus, and presence and pattern of brain injury (particularly deep gray or brainstem injury). Despite this list of potential indicators, accurate prediction of outcome in a given child remains challenging. There is great need for long-term, multicenter studies to examine risk factors for, and pathogenesis of, adverse outcomes following acute symptomatic seizures in neonates.

Abstract
AIM To assess the efficacy and safety of сortexin in the treatment of children with cerebral palsy (CP) combined with epilepsy. MATERIAL AND METHODS Eighty-four patients (55 boys and 29 girls), aged from 1 to 11 years, with CP combined with epilepsy received cortexin together with antiepileptic drugs (AEDs). Cortexin was administered in doses of 5-10 mg depending on the patient's age and body weight intramuscularly during hospitalization. RESULTS AND CONCLUSION Cortexin as add-on to AEDs reduced for more than two times the number of seizures, along with improvement of motor function, in 31 (36.9%) patients. The improvement of motor function, but without a significant decrease in epileptic seizures, was achieved in 15 (17.8%) of the patients. Reduction of epileptic seizures frequency (>2 times), but without a significant effect on motor function, was observed in 14 cases (16.7%). Twenty-three patients (27.4%) did not respond the therapy. The aggravation of epileptic seizures during cortexin therapy was observed in only 1 girl with West syndrome (1.2%), and this was significantly lower than the probability of seizures aggravation on AED. Polypeptide nootropic medication cortexin demonstrated efficacy and safety as adjunctive therapy in children with CP combined with epilepsy.

Abstract
OBJECTIVE The goal of this study was to describe the prevalence, syndromes, and evolution of seizure disorders in children with cerebral palsy (CP) due to white matter injury (WMI). METHODS For this population-based cohort study, brain MRI scans and medical records were reviewed in children in the Victorian Cerebral Palsy Register born between 1999 and 2006 recorded as having WMI. Children were excluded if they had features of an undiagnosed syndrome, associated cortical malformation or injury, or no medical contact in the preceding year. Included were 166 children with CP and isolated WMI due to presumed vascular insufficiency or hemorrhage; 87 were born preterm. Seizure and CP details were obtained from medical records and interviews, and EEG recordings were reviewed. RESULTS Forty-one children (25%) had seizures beyond the neonatal period. Four children had West syndrome, which resolved with treatment. Thirteen children had febrile seizures that they outgrew. Thirty children had focal epilepsy with seizure manifestations and EEG discharges typical of early-onset childhood occipital epilepsy or childhood epilepsy with centrotemporal spikes; 23 have outgrown these seizures. Two children had idiopathic generalized epilepsy; it was ongoing in 1 child. Fourteen children had evolution from 1 epileptic syndrome to another. At last follow-up (median age, 12.7 years; minimum age, 9.7 years), 80% had not had a seizure for >2 years. CONCLUSIONS The electroclinical features of seizure disorders associated with CP and WMI are those of the age-limited, epileptic syndromes of childhood, with favorable outcome in the majority. The findings have important implications for counseling and drug treatment.
