There is an increasing number of patients who have survived after suffering cardiac arrest. Some surviving patients experience prolonged neurological complications due to hypoxic brain injury, of which can result in acute post-hypoxic myoclonus and very rarely, Lance Adams Syndrome (LAS)5. LAS is clinically distinct from acute post-hypoxic myoclonus, which is much more common post-cardiac arrest. Patients who exhibit LAS typically have good outcomes. We present a patient post-cardiac who developed a rare case LAS who initially improved with treatment of levetracitram.
