Olfactory dysfunction in cerebellar ataxia and multiple system atrophy.
Olfactory dysfunction has been reported in Parkinson's (PD) and Alzheimer's disease (AD). ⋯ The present data suggest that olfactory dysfunction is common to various neurodegenerative disorders and not specifically restricted to PD or AD. Cerebellar dysfunction affected suprathreshold olfactory function more severely than odor thresholds. Thus cerebellar lesions may affect the processing of odor-related information to a higher degree than the transport of odorants to the receptor through sniffing.
