You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Disease", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Naloxone", ...], "Disease" : ["Hypotensive", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Myoclonic, atonic, and absence seizures following institution of carbamazepine therapy in children. Five children, aged 3 to 11 years, treated with carbamazepine for epilepsy, had an acute aberrant reaction characterized by the onset of myoclonic, atypical absence and/or atonic (minor motor) seizures within a few days. When the carbamazepine was discontinued, two of the children returned to their former state very quickly, two had the minor motor seizures resolve in 3 and 6 months, and one had the seizures persist. The child in whom the seizures persisted was later found to have ceroid lipofuscinosis. The other children are doing well on other anticonvulsants.
