Sporadic adult‐onset brainstem hyperkalemic periodic paralysis masquerading as recurrent transient ischemic attacks

Abstract

Abstract We report a case of adult‐onset, sporadic, hyperkalemic periodic paralysis with primary brainstem musculature symptoms masquerading as recurrent transient ischemic attacks. Unilateral brainstem weakness could be induced with rapid eye blinking, which was followed by lower extremity weakness and cramping. Treatment with acetazolamide and albuterol ameliorated the patient's attacks.
