Although Klüver-Bucy syndrome in adults is commonly associated with neurodegenerative conditions, Klüver-Bucy syndrome in children has been recognized almost exclusively in association with acute bitemporal injury or dysfunction. We report a child with juvenile neuronal ceroid lipofuscinosis, who developed dementia, childhood-onset autistic disorder, and Klüver-Bucy syndrome. The behavioral features of this case are compared with those of previously reported cases of juvenile neuronal ceroid lipofuscinosis and with previous reports of Klüver-Bucy syndrome in children and adults.
