CLINICAL-ASSESSMENT OF OLFACTORY DYSFUNCTION IN PARKINSONS-DISEASE

We used two simple tasks to lest the capacities of patients with Parki nson's disease to discriminate and identify olfactory stimuli. The pat ients 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 Parkin son's disease. Further clinical data is required for analysis of this dysfunction. We therefore propose simple and rapid tests appropriate f or clinical use with Parkinson's disease patients.
