Alleviation of myoclonus after bilateral pallidal deep brain stimulation for Lance-Adams syndrome.
Lance–Adams syndrome (LAS), which can occur after cardiorespiratory arrest (CPA), is characterized by rest-, action-, and stimulus-sensitive myoclonus with or without other neurological signs such as ataxia, cognitive impair- ment, epilepsy, and pyramidal signs. In 1963, Lance and Adams first described four patients with post- hypoxic generalized myoclonic jerks [6]. Although case reports have been described sporadically, effective thera- pies have not been established. Deep brain stimulation (DBS) is widely used to treat movement disorders such as Parkinson’s disease, dystonia, and myoclonic diseases. Although functional neurosurgery, including intrathecal baclofen therapy (ITB) and DBS, has been performed to treat LAS, evidence for the success of these treatments is scarce. Here, we report a case of LAS treated successfully with bilateral globus pallidus interna (GPi) DBS.
