Lance-Adams Syndrome: A Rare Complication Following Cardiac Arrest

Abstract

Lance-Adams syndrome (LAS) is a rare complication occurring days or weeks following a successful cardiopulmonary resuscitation in which patients develop myoclonus, typically triggered by intentional actions or external stimuli. It can be challenging and confusing to distinguish LAS from acute post-hypoxic status epilepticus, in which patients remain in vegetative or comatose state. Here we report a case of a 71 years old survivor of cardiorespiratory arrest due to cardiogenic shock with typical features of LAS. Although the pathophysiology of LAS is poorly understood, antiepileptic medications are effective in controlling the myoclonus. Early identification of LAS and distinguishing it from myoclonic status is necessary to start appropriate treatment and provide prognosis.
