ABSTRACT=A case of a 12-year-old boy who developed catatonia is presented. He had no previous
	psychiatric history but has a family history of affective disorder. An extensive medical
	work-up was negative. Despite a negative lorazepam challenge test, lorazepam was
	titrated up to 24 mg per day with resolution of most catatonic symptoms. The case
	highlights an important point in the management of catatonia that may be a source of
	confusion, i.e., a positive lorazepam challenge test corroborates the diagnosis of catatonia,
	however, a negative lorazepam challenge test does not negate the diagnosis of catatonia
	and subsequent focused benzodiazepine treatment may still be effective.
