Benign febrile myoclonus in childhood.

BACKGROUND

Myoclonus is often associated with progressive myoclonic epilepsy or neurodegenerative conditions. Febrile myoclonus is a benign phenomenon, which has only been reported previously in one child.

METHODS

The clinical features of three children with fever-induced myoclonus are described.

RESULTS

Fever-induced myoclonus is characterized by frequent myoclonus, which resolves with resolution of the fever in otherwise healthy children.

CONCLUSIONS

Recognition of fever-induced myoclonus as a benign phenomenon may prevent unnecessary investigations and interventions.
