What Causes Febrile Seizures in Children?

Febrile convulsions in children are medically termed “febrile seizures,” primarily resulting from the immature development of the infant’s nervous system—for instance, underdeveloped inhibitory function of the cerebral cortex and incomplete myelination of nerve fibers. Consequently, external stimuli may easily trigger excessive neuronal excitation that spreads rapidly, leading to seizures. Febrile seizures generally fall into two categories:

1. Febrile Seizures: These predominantly occur in children aged 6 months to 5 years. Typically, seizures happen at the onset of fever—or occasionally, fever appears shortly after a seizure. Most episodes are isolated, lasting from several seconds to a few minutes, rarely exceeding 5–10 minutes. Even with occasional recurrence, such seizures usually have minimal impact on cognitive development.

2. Encephalitis: This is comparatively more severe but clinically rare. Children with encephalitis may experience seizures during fever—often severe and difficult to control—and frequently exhibit lethargy or altered mental status. Clinical examination by a physician typically reveals abnormal neurological findings.

If a febrile seizure occurs at home, immediate first-aid measures include applying firm pressure to the *Renzhong* (GV26) acupoint and the *Hegu* (LI4) acupoint, turning the child’s head to one side to prevent aspiration, and initiating physical cooling methods—such as using an ice cap, ice pack, or ice cubes applied to the head to lower brain temperature and protect neurons. Additionally, tepid sponging of the axillae and groin areas can aid in reducing body temperature. If rectal antipyretic medication is available at home, it may be administered rectally. After implementing these initial interventions, promptly transport the child to a clinic or hospital for further evaluation and treatment.
