Prolonged recovery of consciousness in children following symptomatic epileptic seizures
نویسندگان
چکیده
INTRODUCTION There is little published data on the duration of depressed consciousness following epileptic seizures. A prolonged recovery time may be a symptom of underlying brain pathology. This prospective paediatric cohort study investigates whether recovery is prolonged following symptomatic seizures. METHODS Children aged 1-16 years, who had a witnessed seizure in which consciousness was impaired, were recruited. One hundred and twenty eight children (158 seizures) were studied. Seizure aetiology was classified as febrile, idiopathic, remote symptomatic, acute symptomatic and acute on remote symptomatic. At least hourly Paediatric Coma Scale recordings were used to assess recovery time. RESULTS Recovery time was longest for children with acute on remote symptomatic seizures (4.0 h, range 0.89-10.5), followed by those with acute symptomatic seizures (1.94 h, range 0-35.27), remote symptomatic seizures (1.5h, range 0.07-85.5) and idiopathic seizures (0.83 h, range 0.07-13.13). Children with febrile seizures recovered the quickest (0.3h, range 0.05-9). Recovery time was significantly longer (p<0.001, CI 1.96-5.38) following seizures for which rescue antiepileptic drugs were administered compared to those for which it was not. Age, sex, type and duration of seizure did not independently affect recovery time. DISCUSSION Symptomatic seizures take longer to recover than seizures of other aetiologies. It is recommended that a febrile child who presents with a seizure, who has not fully recovered within 30 min, should be investigated for an acute symptomatic aetiology. A high index of suspicion is also needed if children with apparent idiopathic seizures have not fully recovered within 1.5h.

Although treated properly for epilepsy, a number of epileptic children have intractable seizures and about 5-10 per cent of them do not respond to anti -epileptic drugs. In the years 1986-1996 about 10,000 epileptic patients were treated in the Children's Medical Center in Tehran. A retrospective study of their medical records revealed that 41 of them had intractable seizures. I Of these 4...
متن کاملUsefulness of Serum NT-proBNP in Diagnosis of Generalized Seizures in Egyptian Children
Background Seizures may occur in as many as 1% of children. The most urgent type of seizures is generalized tonic-clonic seizures (GTCS). N-terminal prohormone of brain natriuretic peptide (NT‐proBNP) has been considered as a promising biomarker in numerous acute illnesses. We aimed to evaluate usefulness of NT‐proBNP for diagnosis of g...
متن کاملSerum Prolactin Level after Febrile Seizure versus Epileptic Seizure in 6-Month-Old to 5-Year-Old Children
Background: Serum prolactin level has been used as an alternative determinant to help differentiate epileptic from non-epileptic seizures. We aimed to analyze the association between serum prolactin concentration and epileptic seizure versus febrile seizure as well as seizure duration, single versus multiple seizure attacks and time lapse between seizure onset and blood sampling. Methods: Seven...
متن کاملThe Effect of Melatonin on Pediatric Drug-Resistant Epilepsy; a Randomized Double Blind Clinical Trial
BackgroundAbout 15 to 40% of children with seizures are refractory to standard anti-epileptic drugs and for such patients, other treatments such as surgery and the ketogenic diet can reduce seizure frequency. Melatonin is a natural pineal gland hormone. The use of melatonin for controlling pediatric seizures is still controversial. This study aimed to evaluate the effect of melatonin on seizure...

Background & Aim : Sudden Unexpected Death after Epilepsy (SUDEP) is one of potentially lethal side effects of the seizures. Cardiac arrhythmia and myocardial damage have been postulated as underlying causes. On the other hand, serum cardiac troponin I (cTnI) level is one of the most specific cardiac markers for myocardial damage. Therefore, the aim of the present study was to evaluate the l...
