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:

Phenobarbital-induced dyskinesia in a neurologically-impaired child. A 2-year-old child with known neurologic impairment developed a dyskinesia soon after starting phenobarbital therapy for seizures. Known causes of movement disorders were eliminated after evaluation. On repeat challenge with phenobarbital, the dyskinesia recurred. Phenobarbital should be added to the list of anticonvulsant drugs that can cause movement disorders.
