Abstract
- PURPOSE
The aim of this study is to investigate the incidence, clinical features and outcome in pediatric tuberous sclerosis complex(TSC) patients with epilepsy.
METHODS
Fifty seven of 74 patients (77.0%) were included in the study, who were diagnosed with epilepsy associated with TSC from 1991 to 2008. Clinical data were obtained from medical records retrospectively.
RESULTS
Of the 57 patients, initial seizure types were infantile spasms (n=25, 43.8%), complex partial seizure (n=24, 42.1%), generalized tonic seizure (n=5, 8.7%), simple partial seizure (n=2, 3.4%), and atonic seizure (n=1, 1.7%), respectively. Seventeen patients (29.8%) had changes of their seizure types during the clinical course. Excluding the five patients with insufficient data, 52 patients were treated with antiepileptic drugs and four of them underwent epilepsy surgery. Twenty-six of 52 patients (50.0%) with medical treatment and two patients (50.0%) with epilepsy surgery became seizure free. Among the patients with infantile spasms, vigabatrin induced seizure freedom in 13 of 14 patients (92.8%) within four weeks, and five of them maintained seizure remission with vigabatrin monotherapy.
CONCLUSIONS
Half of epileptic patients showed good responses to medical treatment, especially vigabatrin for infantile spasms. Epilepsy surgery can be treatment option for selected patients.
