Introduction
Inability to smell. May be partial, general or specific.
Etiology
- finding common in alpha-synucleinopathy
- Alzheimer's disease
Complications
- nearly double the rate of some types of accidents
- anosmia increases 5-year risk of mortality in the elderly 5-fold[2][4]
- may be risk factor for Parkinson's disease (mostly in older white men)[3]
* Gas is odorless, but the gas company adds a warning 'rotten-egg' smell (mercaptan or a similar sulfur-based compound) that can be easily detected by most people.
