Descriptive study of symptomatic epilepsy by age of onset in patients with a 3-year follow-up at the Neuropaediatric Department of a reference centre. / Estudio descriptivo de las epilepsias sintomáticas según edad de inicio controladas durante 3 años en una Unidad de Neuropediatría de referencia regional.

OBJECTIVE: We conducted a descriptive study of symptomatic epilepsy by age at onset in a cohort of patients who were followed up at a neuropaediatric department of a reference hospital over a 3-year period PATIENTS AND METHODS: We included all children with epilepsy who were followed up from January 1, 2008 to December 31, 2010 RESULTS: Of the 4595 children seen during the study period, 605 (13.17%) were diagnosed with epilepsy; 277 (45.79%) of these had symptomatic epilepsy. Symptomatic epilepsy accounted for 67.72% and 61.39% of all epilepsies starting before one year of age, or between the ages of one and 3, respectively. The aetiologies of symptomatic epilepsy in our sample were: prenatal encephalopathies (24.46% of all epileptic patients), perinatal encephalopathies (9.26%), post-natal encephalopathies (3.14%), metabolic and degenerative encephalopathies (1.98%), mesial temporal sclerosis (1.32%), neurocutaneous syndromes (2.64%), vascular malformations (0.17%), cavernomas (0.17%), and intracranial tumours (2.48%). In some aetiologies, seizures begin before the age of one; these include Down syndrome, genetic lissencephaly, congenital cytomegalovirus infection, hypoxic-ischaemic encephalopathy, metabolic encephalopathies, and tuberous sclerosis. CONCLUSIONS: The lack of a universally accepted classification of epileptic syndromes makes it difficult to compare series from different studies. We suggest that all epilepsies are symptomatic because they have a cause, whether genetic or acquired. The age of onset may point to specific aetiologies. Classifying epilepsy by aetiology might be a useful approach. We could establish 2 groups: a large group including epileptic syndromes with known aetiologies or associated with genetic syndromes which are very likely to cause epilepsy, and another group including epileptic syndromes with no known cause. Thanks to the advances in neuroimaging and genetics, the latter group is expected to become increasingly smaller.

Phenotype in patients with intellectual disability and pathological results in array CGH. / Fenotipo en pacientes con discapacidad intelectual y array-CGH patológico.

INTRODUCTION: Global developmental delay (GDD) and intellectual disability (ID) are frequent reasons for consultation in paediatric neurology departments. Nowadays, array comparative genomic hybridisation (array-CGH) is one of the most widely used techniques for diagnosing these disorders. Our purpose was to determine the phenotypic features associated with pathological results in this genetic test. METHODS: We conducted a blind study of the epidemiological, clinical, anthropometric, and morphological features of 80 patients with unexplained ID to determine which features were associated with pathological results in array-CGH. RESULTS: Pathological results were found in 27.5% of the patients. Factors associated with pathological results in array-CGH were a family history of GDD/ID (OR = 12.1), congenital malformations (OR = 5.33), having more than 3 facial dysmorphic features (OR = 20.9), and hypotonia (OR = 3.25). CONCLUSIONS: Our findings are consistent with those reported by other published series. We therefore conclude that the probability of having pathological results in array-CGH increases with the presence of any of the features mentioned above in patients with ID/GDD.

Our experience with the aetiological diagnosis of global developmental delay and intellectual disability: 2006-2010.

INTRODUCTION: Global developmental delay (GDD) and intellectual disability (ID) are common reasons for consultation in paediatric neurology. Results from aetiological evaluations of children with GDD/ID vary greatly, and consequently, there is no universal consensus regarding which studies should be performed. MATERIAL AND METHOD: We review our experience with determining aetiological diagnoses for children with GDD/ID who were monitored by the paediatric neurology unit over the 5-year period between 2006 and 2010. RESULTS: During the study period, 995 children with GDD/ID were monitored. An aetiological diagnosis was established for 309 patients (31%), but not in 686 (69%), despite completing numerous tests. A genetic cause was identified in 142 cases (46% of the total aetiologies established), broken down as 118 cases of genetic encephalopathy and 24 of metabolic hereditary diseases. Our data seem to indicate that diagnosis is easier when GDD/ID is associated with cerebral palsy, epilepsy, infantile spasms/West syndrome, or visual deficit, but more difficult in cases of autism spectrum disorders. Genetic studies provide an increasing number of aetiological diagnoses, and they are also becoming the first step in diagnostic studies. Array CGH (microarray-based comparative genomic hybridisation) is the genetic test with the highest diagnostic yield in children with unexplained GDD/ID. DISCUSSION: The cost-effectiveness of complementary studies seems to be low if there are no clinically suspected entities. However, even in the absence of treatment, aetiological diagnosis is always important in order to provide genetic counselling and possible prenatal diagnosis, resolve family (and doctors') queries, and halt further diagnostic studies.

[Epilepsy and inborn errors of metabolism]. / Epilepsia y errores congénitos del metabolismo.

INTRODUCTION: Epilepsy is a common manifestation in inborn errors of metabolism, with varying degrees of severity and response to treatment. OBJECTIVE: To determine its incidence and characteristics in metabolic diseases. MATERIAL AND METHODS: A retrospective review of neuropaediatric and metabolic databases was performed. Data on the type of epilepsy, age of onset and refractoriness were collected. RESULTS: Two cases out of three (66%) with molybdenum cofactor deficiency and neonatal epileptic encephalopathy; three with vitamin-sensitive epilepsies: pyridoxamine sulphate oxidase deficiency, antichitin and biotinidase deficiency, early onset and good seizure control with biotin; one with homocystinuria, with late onset and polytherapy; one with Menkes disease difficult to control; two with GLUT-1 deficiencies with absent and generalized discharges in the electroencephalogram; five (33%) peroxisomes in monotherapy, except for a suspected peroxisome biogenesis deficiency; 13 (34%) lysosomal deficiencies; a glycosylation disorder, with infantile and refractory spasms; seven (8.5%) organic aminoacidopathies and acidurias, one with infantile spasms (propionic acidemia), three with nonketotic hyperglycinemia with neonatal epileptic encephalopathy, one with monotherapy (leukinosis) and two (3.3%) with unscreened hyperphenylalaninemia; and five (20%) mitochondrial, most of which had oxidative phosphorylation deficiencies. CONCLUSIONS: The diagnosis of metabolic epilepsy requires a high level of suspicion in unscreened diseases. The semiology of the seizures and the electrocardiogram data are not characteristic, but some clinical data may provide guidance, such as early onset and refractoriness, neuroimaging and some biochemical markers. Although genetic studies are increasingly cost-effective in epilepsy, we must continue to search for earlier biomarkers and test targeted therapeutic trials.

TITLE: Epilepsia y errores congénitos del metabolismo.Introducción. La epilepsia es una manifestación común en los errores congénitos del metabolismo, con gravedad y respuesta al tratamiento variables. Objetivo. Determinar su incidencia y características en enfermedades metabólicas. Material y métodos. Se trata de una revisión retrospectiva de bases de datos de neuropediatría y metabolismo. Los datos recogidos son tipo de crisis, edad de inicio y refractariedad. Resultados. Dos casos de tres (66%) con defecto del cofactor del molibdeno y encefalopatía epiléptica neonatal; tres epilepsias sensibles a las vitaminas: déficit de piridoxamina sulfato oxidasa, déficit de antiquitina y de biotinidasa, de comienzo precoz y buen control de crisis con biotina; una homocistinuria, con inicio tardío y politerapia; una enfermedad de Menkes de difícil control; dos déficits de GLUT-1 con ausencias y descargas generalizadas en el electroencefalograma; cinco (33%) peroxisomales en monoterapia, salvo una sospecha de déficit de biogenia de peroxisomas; 13 (34%) lisosomales; un trastorno de la glucosilación, con espasmos infantiles y refractario; siete (8,5%) aminoacidopatías/acidurias orgánicas, uno con espasmos infantiles (acidemia propiónica), tres con hiperglicinemias no cetósicas con encefalopatía epiléptica neonatal, uno con monoterapia (leucinosis) y dos (3,3%) con hiperfenilalaninemias no cribadas; y cinco (20%) mitocondriales, la mayoría con déficit de la fosforilación oxidativa. Conclusiones. El diagnóstico de epilepsia metabólica precisa un alto índice de sospecha en enfermedades no cribadas. La semiología de las crisis y los datos en el electroencefalograma no son característicos, pero algunos datos clínicos, como el inicio precoz y la refractariedad, de neuroimagen y ciertos marcadores bioquímicos pueden orientar. Aunque los estudios genéticos son cada vez más rentables en la epilepsia, debemos seguir buscando biomarcadores más precoces y probar ensayos terapéuticos dirigidos.

A novel mutation in the ZNF462 gene c.3306dup; p.(Gln1103Thrfs*10) is associated to Weiss-Kruszka syndrome. A case report.

BACKGROUND: Weiss-Kruszka syndrome (WSKA) is a rare disorder caused by mutations in the ZNF462 gene or deletion of 9p31.2 chromosome region, involving ZNF462. The prevalence of WSKA is unknown as only 24 affected individuals have been described. This syndrome should be suspected in individuals presenting mild global developmental delay and common craniofacial abnormalities. CASE PRESENTATION: We presented a case of an infant, 3 years and 4-month life who presented pondostatural and psychomotor retardation, generalized hypotonia with hypermobility, bilateral palpebral ptosis, epicanthal folds, and poorly expressive facies as the main clinical features. These characteristics lead to the realization of genetics studies that resulted in the identification of a novel mutation c.3306dup; p.(Gln1103Thrfs*10) in ZNF462. CONCLUSIONS: WSKA should be suspected in individuals presenting mild global developmental delay, ptosis, downslanting palpebral fissures, exaggerated Cupid's Bow, arched eyebrows, epicanthal folds and short upturned nose with a bulbous tip. Hypertrophy of the ventricular septum and severe OSA were described in our patient and should be considered in future reviews of the disease. This case is added to the reduced number of publications previously reported regarding WSKA and contributes to understanding the genetic characteristics, clinical features, and diagnosis of this syndrome.Abbreviations: WSKA: Weiss-Kruszka syndrome; CP: craniofacial perimeter; WES: whole-exome sequencing; RSV: respiratory syncytial virus; OSA: obstructive sleep apnoea; ACMG: American College of Medical Genetics and Genomics.

Prenatal encephalopathies of unknown origin. Our 19-years experience. To what extent must genetic and biochemical studies be carried out?

INTRODUCTION: We examine those prenatal encephalopathies with clinical or neuroimaging data of encephalopathy before the birth. They affect a significant number of children seen by paediatric neurologists. They can be of disruptive origin (due to vascular problems, drugs, toxins or congenital infections), and genetically determined. We include cases of autism spectrum disorder and mental retardation with no history of perinatal of postnatal damages. MATERIAL AND METHODS: We analysed our 19 year neuro-paediatric data base in search of prenatal encephalopathies and their diagnostic origin. We also analyse the studies made in the cases with a diagnosis of unknown origin. RESULTS: The 19 year period of study in the data base included 11,910 children, and 1596 (13.5%) were considered as prenatal encephalopathies; 1307 children (81.4%) had a diagnosis of unknown origin, despite many investigations being done in a large number of them. DISCUSSION: Most of the children included in this study suffer a rare disease, and whether they are identified or not, they increasingly require an early diagnosis. Peroxisomal, mitochondrial, lysosomal diseases, carbohydrate glycosylation deficiency syndrome and other inborn error of metabolism, congenital infections and genetic encephalopathies, can be clinically indistinguishable in early life and require specific studies to identify them. Early diagnosis requires strategies using step-wise systematic studies, giving priority to those diseases that could be treated, and in many cases using an individualised approach. We believe that the potential benefits of early diagnosis, including savings on further studies, genetic counselling and prenatal diagnosis, overcome the financial costs.

Acute cerebellitis in paediatric patients: Our experience. / Cerebelitis aguda en Pediatría: nuestra experiencia.

INTRODUCTION: Acute cerebellitis is a rare inflammatory disease with a highly variable clinical course that ranges from benign self-limiting symptoms to a fulminant presentation associated with a high risk of death due to compression of the posterior fossa, acute hydrocephalus, and intracranial hypertension. METHODS: We reviewed clinical, laboratory, and radiological findings from children diagnosed with acute cerebellitis between May 2007 and November 2016. We analysed treatments and clinical and radiological progression. RESULTS: Nine children met the diagnostic criteria for cerebellitis. Headache, vomiting, and drowsiness were the most frequent initial symptoms; ataxia, dysarthria, and dysmetria were the most common cerebellar signs. Cerebellitis was diagnosed with magnetic resonance imaging, which revealed cerebellar involvement (unilateral or bilateral); computerised tomography images either were normal or showed indirect signs such as triventricular hydrocephalus due to extrinsic compression of the aqueduct of Sylvius. Corticosteroids were the most commonly used treatment (6 patients). One patient required surgery due to triventricular hydrocephalus. Eight patients recovered completely, whereas the ninth displayed neurological sequelae. CONCLUSIONS: Cerebellitis is a medical and surgical emergency; diagnosis requires a high level of suspicion and an emergency brain magnetic resonance imaging study. It is a clinical-radiological syndrome characterised by acute or subacute encephalopathy with intracranial hypertension and cerebellar syndrome associated with T2-weighted and FLAIR hyperintensities in the cerebellar cortex (unilaterally or bilaterally) and possible triventricular dilatation. Treatment is based on high-dose corticosteroids and may require external ventricular drain placement and decompressive surgery.

[Hereditary juvenile cobalamin deficiency due to mutations in GIF gene]. / Déficit de cobalamina hereditario juvenil causado por mutaciones en el gen GIF.

Inborn errors of cobalamin (Cbl) metabolism affect its absorption, transport, as well as its intracellular metabolism. Hereditary juvenile megaloblastic anaemia due to cobalamin deficiency, results from defects in Cbl absorption. There is a lack of vitamin B12 in congenital pernicious anaemia due to intrinsic factor deficiency and megaloblastic anaemia 1 due to selective intestinal malabsorption of vitamin B12 or Imerslund-Gräsbeck syndrome. Differential diagnosis can't be accomplished only by clinical and biochemical findings. We present a patient from Spain with a megaloblastic anaemia due to intrinsic factor deficiency (IFD). The patient is a compound heterozygous in GIF gene for a splice site mutation inherited from his mother and a missense change inherited from his father. The identification of disease-causing mutations in specific genes has improved our ability to diagnose many of these conditions.

Transition from paediatric care to adult care for patients with mucopolysaccharidosis. / Transición desde la asistencia pediátrica a la adulta en pacientes con mucopolisacaridosis.

Mucopolysaccharidosis are multisystem diseases that require large multidisciplinary teams for their care. Specific recommendations are therefore needed for the transition from childhood to adulthood in this patient group. To overcome the barriers that might arise during the transition, the authors consider it essential to implement a flexible plan with a coordinator for the entire process, systematising the information through a standardised paediatric discharge report and educating the patient and their family about the disease, showing the characteristics of the healthcare system in this new stage. The final objective is that, once the transition to adulthood has been completed, the patient's autonomy and potential development are maximised and that the patient receives appropriate healthcare during this transition.

[Facial paralysis reported in a paediatric emergency department: actuation protocol reviewed and verified]. / Parálisis facial en urgencias de pediatría: actualización de nuestro protocolo y autoevaluación.

INTRODUCTION: As result of our aim to improve the quality standard of our emergency system, work has been carried out in relation to the development and monitorization of effective clinical protocols in the department of paediatric practice. PATIENTS AND METHODS: An evidence based review approach was taken to design a clinical protocol about Bell's palsy condition for the paediatric emergency department. Previous protocol approved in March 2003 was reviewed accordingly with the new designed protocol's quality standards. The Bell's palsy cases reported since March 2003 until June 2006 to paediatric emergency department were analyzed. RESULTS: A total of 27 patients affected by Bell's palsy were reported to the hospital's emergency department. Facial expression was described in 85.19% of the cases. Cranial nerves normal function was reported in 77.78%. Fundoscopic examination was described in 77.78% and otoscopic findings in 44.44%; the absence of herpes vesicles was analyzed only in 11.11%. All patients received steroid therapy (prednisone) and the treatment resulted in the complete recovery. The mean time to resolution was 58.6 days. CONCLUSIONS: In order to improve hospital's quality standards, clinical protocols should be designed and verified regularly to ensure the proper performance. Medical auditing also contributes to improve effectiveness in health attendance.

[A study of the demand for health care in hereditary-metabolic diseases in a Spanish tertiary care hospital]. / Estudio de la demanda asistencial de las enfermedades metabolico-hereditarias en un hospital español de tercer nivel.

AIM: To determine the characteristics of the demand for health care in hereditary-metabolic diseases in a Spanish tertiary care hospital. PATIENTS AND METHODS: We conducted a retrospective descriptive study involving a review of the epidemiological data, reasons for visiting, diagnoses and complementary studies of the patients treated by a metabolic disease unit over a period of 6 years and 11 months. RESULTS: Altogether 1012 patients were evaluated. There was a predominance of males (52%) and of patients under the age of 1 year (42.09%). 71.44% of them were under 6 years old. Approximately half of the patients (50.3%) came from hospitals (wards, outpatients, neonatology, emergency department, neuropaediatrics and intensive care), followed by the neonatal screening programme (20.36%) and primary care (14.82%). The most frequent reasons for visiting and diagnoses can be seen in their respective tables. CONCLUSIONS: The study of the demand for health care in hereditary-metabolic diseases is useful as a means to detect needs in their field and to try to adapt care to meet them. Medical, scientific and social progress makes it necessary to have an expert in metabolism present in reference clinical units. As members of multidisciplinary teams alongside other specialists, they will contribute towards accomplishing a suitable presumptive diagnosis, diagnosis, management and follow-up. It is necessary to keep them constantly up-to-date and ensure adequate training of new experts in metabolism, since this is the best way to deliver optimal care for those with metabolic illnesses, which are usually rare diseases.

Debe estar en continua actualizacion y garantizar la adecuada formacion de nuevos expertos en metabolismo, la mejor via para una optima atencion de los pacientes afectados de enfermedades metabolicas, habitualmente enfermedades raras.

[The primary care paediatrician in attention deficit hyperactivity disorder. An approach involving a population study]. / El pediatra de atención primaria en el trastorno por déficit de atención con hiperactividad. Planteamiento tras un estudio de población.

INTRODUCTION: There is a growing demand for diagnoses of children with learning problems and/or behavioural disorders in visits to paediatric and neuropaediatric units. One of the most frequent causes of this situation is attention deficit hyperactivity disorder (ADHD), which has a high rate of incidence and is difficult to diagnose. The role of the Primary Care paediatrician in its screening and intervention is considered. SUBJECTS AND METHODS: A population study was conducted in children between 6 and 12 years of age who attend schools in the Navarrese towns of Buñuel and Cortes. Conners test--modified and adapted by Farre and Narbona--(ADHS) and DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th edition) diagnostic criteria were used in their evaluation and diagnosis. School grades were also taken into account. In the group of ADHD children, a psychopedagogic and Mental Health evaluation were carried out if there were associated behavioural problems. RESULTS: Findings as regards prevalence, sex and types of ADHD were in line with those in the literature. A statistically significant drop in academic achievement was noted both in children who satisfied ADHD criteria and in those who only met ADHS criteria. 55% of ADHD children who were changing from one academic cycle to another had to repeat their year at school and showed statistically significant differences as compared to the other groups. CONCLUSIONS: The primary care paediatrician must be committed to the diagnosis and treatment of these children without neglecting their evaluation by the different services involved in the diagnostic and therapeutic processes.

[Demand for neuropediatric services in a general referral hospital. III. Diagnosis]. / Estudio de la demanda asistencial de Neuropediatría en un hospital de referencia regional. III. Diagnósticos.

INTRODUCTION AND OBJECTIVES: In order to determine the requirements for neuropaediatric attention in the Hospital Miguel Servet of Zaragoza, we studied the diagnoses of the 2,046 children evaluated during the 5 year period-May 1990 to May 1995-, when a neuropediatrician was appointed to the hospital (which previously did not have such a specialist). RESULTS: The most frequent problems were non-epileptic paroxystic disorders, epilepsies and febrile crises. The following is a list in descending order, of diseases affecting these children: Prenatal encephalopathies, disorders of development and behaviour, head injury (TCE), peripheral nervous system and cranial nerve disorders (which were neither traumatic nor secondary to space-occupying lesions), headaches, perinatal encephalopathies, infections and para-infectious diseases of the nervous system, cardiovascular problems, hydrocephalus, metabolic disorders, hypovision and eye disorders, neuromuscular disorders, tumours, dyskinesias, medulla problems and neurocutaneous syndromes. CONCLUSIONS: The frequency and diversity of the neurological pathology seen in childhood and the continual advances in knowledge and the related sciences are more than a single professional person can be expected to cope with. Experts are required in areas such as electroencephalography and epilepsy, neonatal neurology, the neurological aspects of intensive care, neuropsychology, neuro-oncology, neurometabolic disorders, neurogenetics and neuromuscular disorders. Neuropediatricians are required to control illnesses with great personal, family and social impact, such as the neurocutaneous syndromes and myelomeningocoele. Neuropaediatric services working in close inter-disciplinary collaboration with other specialists are necessary.

[Epidemiological study of the metabolic diseases with homocystinuria in Spain]. / Estudio epidemiológico de las enfermedades metabólicas con homocistinuria en España.

OBJECTIVES: To determine the prevalence of homocystinuria in Spain and to establish the measures and mechanisms to ensure its prevention, diagnosis and treatment. MATERIAL AND METHODS: A national cross-sectional survey was conducted by means of a questionnaire sent to 35 hospitals in which children and adult patients are treated. RESULTS: Using the questionnaires submitted by 25 physicians from 16 centres, 75 patients were identified: 41 transsulphuration defects (one deceased), 27 remethylation (six deaths) and 7 without a syndromic diagnosis. The age at diagnosis varied widely, and 18 cases had more than one sibling affected. The more severe clinical manifestations involved the patients with remethylation defects. There was a high percentage of cognitive impairment, followed by lens diseases. Almost half of the patients had neurological disorders. There was increased vascular involvement in CBS-deficient adults. The therapeutic options most used were, folic acid, hydroxycobalamin and betaine. CONCLUSIONS: In view of these results and especially the small number of CBS deficiencies detected, we conclude that there is a need to introduce newborn screening for classical homocystinuria and ensure implementation of an appropriate diagnostic workup in all patients at risk.

[Continuous monitoring of a guideline: Bell's palsy]. / Monitorización continua de un protocolo: parálisis facial a frigore.

INTRODUCTION: The preparation and review of child neurology guidelines can reduce the variability of our medical practice, thus improving health care. We present the continuous monitoring of our Bell's palsy guideline. MATERIAL AND METHODS: Emergency and medical reports of the children seen in Child Neurology surgery from July 2006 to August 2009 (group 2) are reviewed for the purpose of finding out the present level of compliance with guideline quality criteria and compare it with the previously reviewed period (group 1, from March 2003 to June 2006). Scientific evidence on this topic is also updated. RESULTS: Comparing the compliance rate in group 1 with group 2 shows a rise in group 2 from 85.1% to 100% in facial expression description, from 11.1% to 31.6% on whether or not there is evidence of Herpes Zoster vesicles, from 77.7% to 84.2% whether or not there is evidence fundoscopic examination, and from 77.7% to 86.8% as regards cranial nerve function remaining normal. The rate of fact sheet issue, recorded for the first time in group 2, is 21.1%. DISCUSSION: Medical auditing allows us to evaluate our medical practice and set up ways for improvement according to the deficiencies found. We insist on striving to improve the written record of the most relevant data and never overlook the importance of issuing the fact sheets to parents and paediatricians, to ensure continuity of medical care.

[Epilepsy onset between one month and three months of life: our 11 years experience]. / Epilepsia de inicio entre el mes y los tres meses de vida: nuestra experiencia de 11 años.

INTRODUCTION: The prognosis of epilepsy is basically determined by its aetiology. Early onset of seizures is generally associated with poor progress. MATERIAL AND METHODS: We review our experience in epilepsy with children born after 1 January 1997 and who had their first seizure between 1 and 3 months of age before January 2008. RESULTS: Eighteen cases diagnosed with epilepsy and a first seizure between 1 and 3 months of age were included. One case was within the Dravet syndrome spectrum with the c829 T>G c277G heterozygous mutation of the SCN1A gene. Four were cryptogenic epilepsies and thirteen were asymptomatic: 2 were inborn errors of metabolism (biotinidase deficiency with a response to biotin and Leigh's syndrome); 2 were of infectious origin and the remaining nine prenatal encephalopathy. Nine (50%) currently have a severe psychomotor delay and 2 died. The cryptogenic cases had a relatively poor progress. CONCLUSIONS: Our experience corroborates the poor prognosis associated with early onset, between 1 and 3 months, of epileptic seizures. Given the wide aetiological range and the poor prognosis in the absence of specific treatment, an appropriate diagnostic-therapeutic strategy is required to avoid diagnostic uncertainties and can identify potentially treatable cases, such as some inborn errors of metabolism. In this age group, the protocol for convulsions of unknown cause must be the same as that for neonatal convulsions, including treatment with a vitamin cocktail, after collecting biological samples.
