title: Levetiracetam monotherapy in newly diagnosed cryptogenic West syndrome.
abstract: The combination of axial spasms in clusters, hypsarrhythmia, and psychomotor delay beginning in the first year of life defines West syndrome. Adrenocorticotrophic hormone remains the choice of treatment for many neurologists. Recent controlled studies support vigabatrin as first-line therapy, and open-label studies suggest that topiramate, lamotrigine, and zonisamide may be useful in treating spasms. Studies regarding the efficacy and safety of such treatments often come from small, uncontrolled trials and are often inconclusive. Levetiracetam is effective for treating localization-related epilepsy, but it is uncertain whether it is effective for treating West syndrome. To evaluate the efficacy of levetiracetam monotherapy in newly diagnosed cryptogenic West syndrome, levetiracetam was used initially in the treatment of five patients with cryptogenic West syndrome. On admission, levetiracetam (30 mg/kg) tablets were crushed and administered via nasogastric tube. Two patients were seizure free, two patients experienced a 50% reduction in seizure frequency, and one patient had no improvement in seizure frequency. There were no relapses in the two patients at 6 months after the cessation of seizures. It appears that levetiracetam may be effective in the initial treatment of selected patients with cryptogenic West syndrome.
