Long-term outcomes after childhood convulsive status epilepticus.

PURPOSE OF REVIEW
It is widely accepted that childhood convulsive status epilepticus (CSE) has associated short-term and long-term mortality and morbidity. However, the role of CSE itself on subsequent adverse outcomes is still debated. In addition, whether prolonged seizures cause any long-term hippocampal injury and developmental or memory impairment is uncertain. In this review, we aim to provide an overview of long-term outcomes after childhood CSE, highlighting data from recent literature on this subject.


RECENT FINDINGS
Long-term outcome after childhood CSE is favorable in previously normal children, with low incidence of epilepsy, motor and intellectual disability, behavioral impairment and need for special educational provision. Mesial temporal sclerosis is uncommon in children after prolonged febrile seizures. There is substantial morbidity after childhood CSE, but this is seen primarily in children with symptomatic causes and preexisting neurological abnormalities. Cause is the primary determinant of outcomes after childhood CSE and the additional effect of CSE characteristics such as seizure duration seems to be less than previously believed.


SUMMARY
Childhood CSE is associated with substantial neurological, cognitive and behavioral morbidity. Early identification of these difficulties and appropriate intervention are likely to have a major positive impact on their quality of life.
