What is the management approach for new onset seizures in a child?

From the Guidelines

The management of new onset seizures in a child begins with a comprehensive evaluation, and for a first unprovoked seizure, observation without antiepileptic medication is often recommended, as the risk of recurrence is relatively low, and the potential side effects of medication may outweigh the benefits, as noted in studies such as 1 and 1. The evaluation should include a detailed history, physical examination, and appropriate diagnostic testing such as an electroencephalogram (EEG) and neuroimaging.

• The history should focus on the seizure characteristics, including duration, frequency, and any potential triggers.
• The physical examination should assess for any focal neurological deficits or signs of underlying neurological conditions.
• Diagnostic testing, such as EEG and neuroimaging, can help identify any underlying structural or functional abnormalities that may be contributing to the seizures. For a first unprovoked seizure, the risk of recurrence is 30-50%, and the decision to start antiepileptic medication should be based on individual risk factors, such as an abnormal EEG or structural brain abnormality, as discussed in 1 and 1.
• First-line medications for focal seizures include levetiracetam (20-60 mg/kg/day divided twice daily) or oxcarbazepine (8-40 mg/kg/day divided twice daily), while for generalized seizures, valproic acid (15-60 mg/kg/day divided twice daily) or levetiracetam are commonly used, as noted in various studies, but the most recent and highest quality study 1 provides the most relevant guidance.
• Medication should start at a low dose and gradually increase to minimize side effects.
• Regular follow-up is essential to monitor seizure control, medication side effects, and developmental progress.
• Parents should be educated about seizure first aid, including placing the child on their side, not restraining movements, and not putting anything in the mouth, as recommended in 1 and 1.
• Emergency medical attention is warranted for seizures lasting more than 5 minutes or if the child doesn't regain consciousness, as emphasized in 1 and 1. The goal of treatment is to control seizures while minimizing medication side effects and supporting normal development and quality of life, as highlighted in 1, 1, and 1.
• This approach prioritizes the child's morbidity, mortality, and quality of life, and is supported by the most recent and highest quality evidence, including 1 and 1.

Management Approach for New Onset Seizures in a Child

The management of new onset seizures in a child involves a comprehensive approach that includes diagnosis, treatment, and follow-up care.

• Diagnosis: The first step in managing new onset seizures is to diagnose the underlying cause of the seizures. This can be done through a combination of physical examination, medical history, and diagnostic tests such as electroencephalogram (EEG) and imaging studies 2.
• Treatment: The treatment of new onset seizures typically involves the use of antiepileptic drugs (AEDs). The choice of AED depends on the type of seizure, the age and weight of the child, and the presence of any underlying medical conditions. According to a study published in The Cochrane database of systematic reviews, levetiracetam, lamotrigine, and sodium valproate are effective AEDs for the treatment of partial onset seizures and generalized tonic-clonic seizures 3.
• Follow-up care: Regular follow-up care is essential to monitor the child's response to treatment, adjust the dosage of AEDs as needed, and prevent potential side effects. A study published in Continuum (Minneapolis, Minn.) highlights the importance of follow-up care in managing seizures and preventing complications 4.

Antiepileptic Drugs for New Onset Seizures

Several AEDs are available for the treatment of new onset seizures in children. These include:

• Levetiracetam: A study published in Caspian journal of internal medicine found that levetiracetam is effective in controlling seizures in patients with juvenile myoclonic epilepsy 5.
• Lamotrigine: Lamotrigine is another AED that is commonly used to treat new onset seizures. However, a study published in International journal of clinical pharmacy found that lamotrigine may not be as effective as other AEDs, such as levetiracetam and sodium valproate, in controlling seizures 6.
• Sodium valproate: Sodium valproate is a widely used AED for the treatment of generalized epileptic seizures. However, it may have adverse effects, particularly in women of childbearing age 3, 5.

Considerations for Treatment

When selecting an AED for a child with new onset seizures, several factors should be considered, including:

• Efficacy: The AED should be effective in controlling seizures and preventing complications.
• Safety: The AED should have a favorable safety profile, with minimal side effects.
• Age and weight: The AED should be suitable for the child's age and weight.
• Underlying medical conditions: The AED should be chosen based on the presence of any underlying medical conditions, such as liver or kidney disease.
• Potential interactions: The AED should not interact with other medications the child is taking 3, 4, 5, 6.
