Study Notes
Seizures in Children
- Seizures are uncontrolled nerve firings in the brain
- Generalized seizures involve both cerebral hemispheres
- Focal seizures involve one hemisphere
- Young infants' seizures can be subtle and look different from other seizures
Learning Objectives
- Identify different types of seizures in children
- Differentiate the causes of seizures
- Recognize components of a seizure workup
- Discuss treatment for seizures in children
Seizure Prevalence
- Seizures affect 1% of the population
- Febrile seizures occur in 4-10% of the population
- 15% of children with an initial seizure will have another within a year.
During a Seizure
- Alteration of vital signs and respiratory suppression are possible
- A period of sleepiness (post-ictal period) follows a seizure
- Transient paralysis (Todd's paralysis) can develop after a seizure
- Seizures vary depending on where they start in the brain
Types of Seizures
- Tonic-clonic (generalized): May be tonic or clonic
- Focal (one side of the body)
- Myoclonic: Few to many short jerks in the body
- Atonic/Akinetic: "Drop spells"
- Absence: No jerking; "staring spells"
Status Epilepticus
- A seizure lasting more than 30 minutes
- Can result in death
Differential Diagnosis of Seizures
- Infections (e.g., brain abscess, encephalitis, meningitis, tuberculosis, viral illnesses, HIV, toxoplasmosis)
- Toxins (e.g., cocaine, methamphetamine, lead poisoning, organophosphates, salicylates, sympathomimetics, tricyclic antidepressants, alcohol withdrawal)
- Traumatic/Vascular (e.g., cerebral contusion, stroke, child abuse)
- Idiopathic (Epilepsy)
- Congenital Anomalies
- Genetic causes
- Metabolic causes (e.g., hypercarbia, hypocalcemia, hypoglycemia, hyponatremia, hypomagnesemia, inborn errors of metabolism, pyridoxine deficiency)
- Neoplastic (e.g., brain tumors, metastatic cancers)
Infantile Spasms
- General myoclonic jerking of neck, trunks, and limbs
- Typically begins between 3-7 months old
- Associated with some genetic syndromes
- Atypical EEG finding: "hypsarrhythmia"
- Poor prognosis: Death within 3 years in 1/3 of children
- Often has profound cognitive effects
- Difficult to control seizures
- Survivors may develop other seizure types
Benign Rolandic Epilepsy
- Simple partial seizures often involving face and hands
- EEG shows centrotemporal spikes
- Seizures occur or are aggravated during or around sleep
- Almost always outgrown by adolescence
Conditions That Mimic Seizures
- Breath holding spells
- Syncope
- Panic attacks
- Tic disorders
- Benign myoclonus (infants)
- Dystonic reaction
- Pseudoseizures
- Night terrors
Seizure Workup - Basic
- EEG
- Electrolytes (to rule out metabolic anomaly)
- CBC (to rule out infection)
Additional Workup
- Depends on assessment and physical exam findings
- Sometimes requires head CT or MRI
Treatment: Febrile Seizures
- Loosen tight clothing to prevent injury
- Protect the person from injury
- Place something soft under their head if they fell
- Stay with them until fully recovered
- Call for medical help if seizure lasts over 5 minutes
- Do not try to restrain the person
- Do not put anything between their teeth
- Do not move them unless they are in danger
- Do not give them food
Acute Seizure Control
- Treatment varies depending on the duration and type of seizure, presence of complications and the underlying cause. Multiple medications are used in the acute setting.
Anticonvulsants (Medication)
- Many different drugs with varying mechanisms of action.
- Side effects are listed in the accompanying table.
Medication Side Effects
- Valproic Acid/Phenytoin: May cause fetal anomalies, gum hyperplasia. Blood levels need monitoring.
- Phenobarbital: Long-term cognitive effects
- Lamotrigine: Can lead to Stevens-Johnson syndrome
Non-Pharmacological Seizure Treatment
- Vagal Nerve Stimulator
- Surgery
- Ketogenic Diet
Febrile Seizures
- Occurs in approximately 4% of children (6-60 months) associated with a febrile illness
- Most common form of seizures and neurological disorders in children
- 30-40% of children with febrile seizures will have a recurrence.
- General risk of epilepsy 0.5 - 1%. Risk in febrile seizure patients is 1-2%.
Simple Febrile Seizures
- Symmetrical
- Lasts less than 15 minutes (Most <5 minutes)
- Only one seizure associated with a febrile illness/24 hour timeframe.
Complex Febrile Seizures
- Focal features during or after event
- Lasts more than 15 minutes.
- More than one seizure in a 24-hour period.
Febrile Seizures & Epilepsy
- Dravet Syndrome: Severe myoclonic epilepsy of infancy (prolonged, asymmetric, progressive, starts without fevers)
- Generalized Epilepsy with Febrile Seizures Plus (GEFS+): Autosomal dominant, febrile seizures can disappear by age 6, or evolve.
