Olfactory dysfunction in neurodegenerative disorders Emerging evidence indicates that olfactory deficits—such as impaired odor detection and discrimination—manifest early in these diseases, preceding cognitive and motor symptoms by several years (Ross et al., 2008; Doty, 2017).
A smell disorder can be an early sign of Parkinson's disease, Alzheimer's disease, or multiple sclerosis. It can also be related to other medical conditions, such as obesity, diabetes, hypertension, and malnutrition. If you are experiencing a smell disorder, talk with your doctor.
Sensorineural defects involve the more central neural structures. Overall, the most common causes of primary olfactory deficits are aging, nasal and/or sinus disease, prior viral upper respiratory tract infections (URTIs), and head trauma.
