Hemiconvulsion-hemiplegia-epilepsy Syndrome: A Case Series.

Hemiconvulsion-hemiplegia-epilepsy (HHE) syndrome is an uncommon outcome of prolonged focal status epilepticus in childhood. We present four cases with age between 6 months and 3 years diagnosed with HHE syndrome. Two patients were lost to follow-up; other two cases had severe developmental delay and refractory epilepsy. An early diagnosis, a good seizure control, and a better understanding of the underlying mechanisms of HHE are needed to improve the outcome of this condition.
