Hippocampal volume in childhood seizures

Many children with hippocampal sclerosis underwent surgery for treatment. Early childhood convulsion occurs in 2 to 4% of population and its prognosis is good in majority of cases. It seems that hippocampal anomalies are common in patients with neocortical epilepsies. The theory of hippocampal sclerosis association with temporal lobe epilepsy has been proposed 100 years ago. Recent studies demonstrated that there was a correlation between memory impairments and prolonged febrile convulsion (PFC), which might be a result of hippocampal injury. Transient hippocampus swelling might happen in complicated early childhood epilepsy or status epilepticus and result in hippocampal sclerosis.
