ABSTRACT
Objective To evaluate the olfactory functions in patients with Parkinson's disease (PD) with a smell identification test developed for the Chinese population and to examine possible factors contributing to PD patients' olfactory performance.Methods Fifty-five patients with idiopathic and nondementia PD and 55 demographically matched healthy controls (HC) were recruited and their olfactory identification tested using the Chinese Smell Identification Test developed by the Institute of Psychology at Chinese Academy of Sciences.Results Olfactory identification score was significantly lower (t =-6.827,P<0.01) in the PD group (19.3 ±5.4) as compared with the HC group (26.5 ±5.7).Of all PD patients,63.6% scored over 1 SD below the age norm.In particular,of those with Hoehn-Yahr ratings between 2 to 3,77.8% scored over 1 SD below the age norm.Receiver operating characteristic (ROC) curve analysis indicated that a cut-off score of 22.5 on the Chinese Smell Identification Test distinguished between PD patients and HC with a sensitivity of 74.6% and specificity of 70.9%.Within the PD group,age,education,Hoehn-Yahr rating and Mini-Mental State Examination score were not found to correlate with olfactory performance (all P > 0.05).Conclusion PD patients in China show significant impairment of olfactory identification,which is effectively captured by the Chinese Smell Identification Test.
