RT Journal Article SR Electronic T1 Odour identification test and its relation to cardiac 123I-metaiodobenzylguanidine in patients with drug induced parkinsonism JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 1250 OP 1252 DO 10.1136/jnnp.2007.121285 VO 78 IS 11 A1 Lee, Phil Hyu A1 Yeo, Seung Hyeon A1 Yong, Seok Woo A1 Kim, Yun Joong YR 2007 UL http://jnnp.bmj.com/content/78/11/1250.abstract AB We investigated olfactory function and its relation to cardiac 123I-metaiodobenzylguanidine (MIBG) uptake in 15 patients with drug induced parkinsonism (DIP). The mean Cross Cultural Smell Identification (CCSI) score was significantly greater in patients with DIP than in those with Parkinson’s disease (PD: 6.9 (1.6) vs 4.4 (2.2); p<0.001); however, the mean CCSI score in patients with DIP was not significantly different from controls. One patient with DIP, whose CCSI score was significantly reduced, also exhibited decreased cardiac MIBG uptake. DIP patients with CCSI scores within the normal range had normal cardiac MIBG uptake. Our study suggests that an olfactory function test may be a useful tool for detecting DIP unrelated to PD and for identifying patients with DIP who have subclinical PD.
