Published by Elsevier Ltd. All rights reserved.Several neurological manifestations may be associated with hyperosmotic hyperglycemic nonketotic state (HHNK). Forty percent of HHNK patients have acute symptomatic seizures, mostly focal. Motor seizures, such as epilepsia partialis continua, are the most common, while non motor ones are less recognized.
