West syndrome in children with tuberous sclerosis complex can improve, contrary to previous reports. EEG sleep patterns showed promise in predicting seizure control, while steroid therapy duration did not impact outcomes.

Area of Science:

  • Pediatric Neurology
  • Epileptology
  • Genetics

Background:

  • West syndrome is common in tuberous sclerosis complex (TSC), often linked to poor cognitive and seizure prognosis.
  • Previous studies suggest high mortality and intractable epilepsy in these children.

Purpose of the Study:

  • To investigate epilepsy outcomes in children with TSC and West syndrome.
  • To identify factors (EEG, MRI, steroid therapy) differentiating seizure improvement from intractable epilepsy.

Main Methods:

  • Retrospective analysis of 17 patients with TSC and West syndrome.
  • Collected serial EEG, MRI, and treatment data over at least 12 months.
  • Compared data between groups with improved versus intractable seizures.

Main Results:

  • Seizure control improved in 10 patients and worsened in seven; no mortality observed.
  • No significant differences found in EEG background, MRI findings, or steroid treatment duration.
  • EEG sleep patterns approached statistical significance as an indicator of seizure control (P = 0.06).

Conclusions:

  • Findings challenge reports of uniformly poor epilepsy outcomes and high mortality in this population.
  • EEG sleep patterns may be a valuable indicator for seizure control in West syndrome with TSC.
  • Steroid therapy duration did not influence long-term seizure control.
