Febrile seizures: a population-based study

Area of Science:

• Pediatric Neurology
• Epidemiology

Background:

• Febrile seizures are common in childhood.
• Understanding their prevalence and characteristics is crucial for public health.

Purpose of the Study:

• To determine the prevalence of benign febrile seizures in childhood.
• To describe the clinical and epidemiological profile of affected children.

Main Methods:

• Population-based, cross-sectional study conducted in Barra do Bugres, MT, Brazil.
• Two-phase data collection: validated questionnaire followed by neurological evaluation.
• Study period: August 2012 to August 2013.

Main Results:

• Prevalence of 6.4/1000 inhabitants (95% CI: 3.8-10.1).
• No significant gender difference observed.
• Simple febrile seizures accounted for 88.8% of cases.
• Family history of febrile seizures (33.3%) and epilepsy (11.1%) were noted.

Conclusions:

• Lower prevalence of febrile seizures in Midwestern Brazil compared to other regions.
