Seizures
• Transient occurrence of signs and/or symptoms resulting from abnormal excessive or synchronous neuronal activity in the brain
Seizures
• Either:
1.Focal (partial) initial activation of a system of neurons limited to part of one cerebral hemisphere
• Generalized synchronous involvement of all of both hemispheres
Febrile Seizures
• Occur between the age of 6 and 60 months
• Temperature of 38°C or higher
• Not the result of central nervous system infection or any metabolic imbalance
• Occur in the absence of a history of prior afebrile seizures
Simple or Complex?
Simple •Primary generalized•Usually tonic-clonic, attack associated with fever•Lasts for a maximum of 15 min•No recurrence within 24 hours
Complex •More prolonged (>15 min)•Focal •Recurs within 24 hours
Febrile status epilepticus febrile seizure lasting >30 min.
Febrile Seizures
• Between 2% and 5% of neurologically healthy infants and children experience at least 1
• Do not have an increased risk of mortality• No long-term adverse effects of having ≥1
simple febrile seizures (No brain damage)• Only 2-7% of children who experience febrile
seizures proceed to develop epilepsy later in life
All in the family
• In many families, the disorder is inherited as an autosomal dominant trait
• Multiple single genes causing the disorder have been identified
• In most cases the disorder appears polygenic, and the genes predisposing to it remain to be identified
Genes, genes, genes
• Identified single genes include FEB 1, 2, 3, 4, 5, 6, and 7 genes on chromosomes 8q13-q21, 19p13.3, 2q24, 5q14-q15, 6q22-24, 18p11.2, and 21q22
• Only the function of FEB 2 is known: it is a sodium channel gene, SCN1A
Some syndromes
• Almost any type of epilepsy can be preceded by febrile seizures
• A few epilepsy syndromes typically start with such
• Generalized epilepsy with febrile seizures plus (GEFS+)
• Severe myoclonic epilepsy of infancy (SMEI, also called Dravet syndrome)
• And, in many patients, temporal lobe epilepsy secondary to mesial temporal sclerosis
Work Up
Lumbar Puncture
• Recommended in children <12 mo of age after their first febrile seizure to rule out meningitis
• Especially important if the child has received prior antibiotics mask clinical symptoms of the meningitis
• The presence of an identified source of fever, such as otitis media, does not eliminate the possibility of meningitis
Lumbar Puncture
• Seizures are the major sign of meningitis in 13-15% and 30-35% of such children have no other meningeal signs
• American Academy of Pediatrics (AAP) strongly recommends LP in infants <1 yr of age because other signs of the infection might not be present
Lumbar Puncture
• A child between 12 and 18 mo of age should also be considered Clinical symptoms of meningitis may be subtle in this age group
• For children >18 mo of age indicated in the presence of clinical signs and symptoms of meningitis (e.g., neck stiffness, Kernig sign, Brudzinski sign) or if the history and/or physical examination otherwise suggest intracranial infection
Electroencephalogram
• Not needed if the child is presenting with his or her first simple febrile seizure and is otherwise neurologically healthy
• Would not predict the future recurrence of febrile seizures or epilepsy even if the result is abnormal
• Spikes during drowsiness are often seen in children with febrile seizures, particularly those >4 year old, and these do not predict later epilepsy
EEG
• Often have nonspecific slowing, if performed within 2 weeks usually posteriorly. Thus, in many cases, if an EEG is indicated, it is delayed until or repeated after >2 weeks have passed
• Generally restricted to special cases in which epilepsy is highly suspected
• Should be used to delineate the type of epilepsy rather than to predict its occurrence
EEG
• Should be performed for at least 30 min in wakefulness and in sleep avoid misinterpretation and drawing of erroneous conclusions
• At times, if the patient does not recover immediately from a seizure, it can help distinguish between ongoing seizure activity and a prolonged postictal period -- nonepileptic twilight state (NETS).
Neuroimaging
• According to the AAP a CT or MRI is not recommended after a first simple febrile seizure
• Patients with febrile status epilepticus have been reported to have swelling of their hippocampus acutely and subsequent long-term hippocampal atrophy. These patients may be candidates for neuroimaging, because they may be at risk for later temporal lobe epilepsy
Remember…
• The work-up of children with complex febrile seizures needs to be individualized
• This can include EEG and neuroimaging, particularly if the child is neurologically abnormal
• Patients with febrile status epilepticus swelling of their hippocampus acutely and subsequent long-term hippocampal atrophy which puts them at risk for later temporal lobe epilepsy
Treatment
• In general, antiepileptic therapy, continuous or intermittent, is not recommended for children with one or more simple febrile seizures
• Counseling on the relative risks of recurrence of febrile seizures and recurrence of epilepsy, how to handle a seizure acutely plus emotional support
Treatment
• If the seizure lasts for >5 min acute treatment with diazepam, lorazepam, or midazolam – Rectal diazepam is often prescribed – Buccal or intranasal midazolam may be used
and is often preferred by parents– IV benzodiazepines, phenobarbital,
phenytoin, or valproate may be needed in the case of febrile status epilepticus
Treatment
In the vast majority of cases it is not justified to use these medications for intermittent therapy Risk of side effects and lack of demonstrated long-term benefits, even if the recurrence rate of febrile seizures is expected to be decreased
Treatment
Antipyretics
•Can decrease the discomfort of the child but do not reduce the risk of having a recurrent febrile seizure (seizure often occurs as the temperature is rising or falling)
Treatment
• Chronic antiepileptic therapy may be considered for children with a high risk for later epilepsy
• Currently available data indicate that the possibility of future epilepsy does not change with or without antiepileptic therapy
• Screen for iron deficiency, as it has been shown to be associated with an increased risk of febrile seizures
Prognosis
• Benign events with excellent prognosis
