Febrile Seizures in Adults: Causes, Risks & What to Do
Febrile seizures are convulsions triggered by fever, typically in children 6 months–5 years. In adults, they are rare and usually indicate an underlying neurological or systemic condition.
Potential Causes in Adults
- Central nervous system infection (meningitis, encephalitis)
- Traumatic brain injury
- Stroke or intracranial hemorrhage
- Metabolic derangements (hyponatremia, hypoglycemia)
- Drug withdrawal (alcohol, benzodiazepines)
- Autoimmune encephalitis
- Brain tumor
Action
Any adult with a first-time seizure (febrile or not) requires urgent medical evaluation – neuroimaging, lumbar puncture, labs, EEG. Do not assume it is a benign febrile seizure.
