The results of previous studies in small groups of Parkinson's disease (PD) patients are inconclusive with regard to the presence of an odor recognition memory impairment in PD. The aim of the present study was to investigate odor recognition memory in PD in a larger group of patients. Odor recognition memory and detection thresholds were assessed using components of the "Sniffin' Sticks" test battery in 55 non-demented PD patients (Hoehn and Yahr stages I-III) and 50 control subjects of comparable age and sex. PD patients performed slightly but significantly worse than control subjects on the odor recognition memory task. After correction for odor detection scores, however, the difference in odor recognition memory performance between PD patients and controls was no longer statistically significant. These data indicate that odor recognition memory is not independently impaired in PD patients
