Are fever-induced seizures common in adults?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Fever-induced seizures, also known as febrile seizures, are rare in adults and occur most commonly in young children between 6 months and 5 years of age. When seizures do occur alongside a fever in adults, they typically signal an underlying condition—such as an infection, neurological disorder, or metabolic imbalance—rather than a simple febrile response.

Because a seizure with fever in adulthood is unusual, identifying the root cause quickly is important for proper treatment. Taking a free, instant, online symptom check can help you clarify possible causes, understand urgency, and guide your next steps before speaking with a healthcare provider.

Explanation

Fever-induced seizures, also known as febrile seizures, are not common in adults. They are typically seen in children. There are rare cases where adults may experience seizures related to fever, but these instances are unusual.

Reference 1 discusses a case where an adult had febrile convulsions, but this is not common and was a unique presentation.
Reference 2 focuses on the natural history of fever following a seizure. It implies that while fever can occur after a seizure, it does not necessarily mean the fever caused the seizure.
Reference 3 talks about the evaluation of adults with fever in emergency settings, suggesting that other causes should be considered when adults present with seizures and fever.

In summary, adults experiencing seizures with fever should be evaluated for other potential causes, as febrile seizures are not typical in this age group.
