Which cause of seizures is more prevalent in the pediatric population compared to the geriatric population?

High fever, or fever-associated seizures, is a common cause of seizures in children, particularly in those between the ages of 6 months and 5 years. These seizures can occur when a child's body temperature rises rapidly, often due to infections such as viral illnesses. This phenomenon is known as a "febrile seizure."

In the pediatric population, high fever is a relatively frequent occurrence, and the immature nervous system in young children can be especially sensitive to changes in temperature. This is in contrast to the geriatric population, where high fevers due to infection are less common, and when they do occur, they may not trigger seizures as frequently as they do in children due to differences in physiological responses and underlying health conditions.

Thus, the prevalence of high fever as a cause of seizures is significantly higher in children compared to older adults, making it the correct answer to the question about the differing causes of seizures across age groups.
