- Familial febrile seizures are a category of disorders in which convulsive seizures occur along with fever within a family.
- Genetic susceptibility to fever and family history can influence the likelihood and patterns of febrile seizures.
- Fever can lower the seizure threshold in children, and with a genetic predisposition, abnormal electrical activity in the brain can manifest as seizures.
- Typically, when a fever occurs, there is a temporary loss of consciousness and convulsions such as body stiffness or shaking, with generalized patterns being common.
- The form of seizures and the possibility of recurrence may vary depending on family history, the cause and degree of fever, developmental status, and an individual's genetic background.
- Febrile seizures mainly appear in childhood and often improve with growth, but they can recur; if there are afebrile seizures or developmental abnormalities, other seizure disorders must be evaluated.
- Diagnosis is centered on clinical evaluation, integrating the presence or absence of fever during the seizure, duration and pattern, recovery process, medical history, and family history.
- Even if it appears to be a febrile seizure, central nervous system infections, metabolic abnormalities, or afebrile epileptic seizures must be differentiated, and EEG and brain imaging tests are selected according to the clinical situation.
- The key to management is ensuring safety to prevent injury during seizures, responding appropriately to prolonged or recurrent seizures, and evaluating the cause of fever and the possibility of recurrence.
- For short and typical febrile seizures, long-term preventive treatment is not always necessary, and the decision regarding treatment is made considering the seizure pattern and underlying disease.
