We used two simple tasks to test the capacities of patients with Parkinson's disease to discriminate and identify olfactory stimuli. The patients presented defective odor identification abilities whereas their capacity to discriminate between odors was apparently unaffected. This raises a question about the nature of olfactory dysfunction in Parkinson's disease. Further clinical data is required for analysis of this dysfunction. We therefore propose simple and rapid tests appropriate for clinical use with Parkinson's disease patients.
