ETIOPATHOGENESIS OF FEBRILE SEIZURES

Febrile seizures (FS) are the most common seizure disorder in young children. They typically happen between 6 months and 5 years of age when a child has a fever — but no brain infection, metabolic problem, or history of seizures without fever. The causes are complex and involve several things working together: a child’s genes, how their brain is still developing, and the body’s natural inflammatory response to infection. Recent research has spotlighted one key player — a chemical called interleukin-1β (IL-1β) — that ramps up brain cell activity and makes seizures more likely. This article explains the main triggers and mechanisms in plain language.
