Seizures in infants and children are most commonly caused by what condition?

Seizures in infants and children are most commonly precipitated by fever, a condition known as febrile seizures. This type of seizure typically occurs in young children, usually between the ages of 6 months and 5 years, and is often associated with a rapid increase in body temperature due to infections, such as viral illnesses. The body's response to fever can lead to electrical activity in the brain that manifests as a seizure.

Febrile seizures are generally benign, meaning they are not usually associated with any underlying serious neurological conditions, whereas seizures due to primary seizure disorders, head injuries, or sleep apnea can indicate more complex issues requiring different management strategies. Understanding the common causes of seizures in this age group is crucial for prompt and appropriate care, making the association with fever particularly significant in pediatric emergency medicine.
