Links between loss of smell, anhedonia and reduced quality of life have been recently described, 42,43 as has an asso ciation between anhedonia and decreased performance on smell identification. 21 Increased ability to identify the origins of odours may heighten vigilance and produce fear in individuals unable to use higherlevel processes to evaluate the context of the sen sory experience.…”

The risk of olfactory dysfunction increases with age related to disruption anywhere along the sensory process (Rawson 2006).…”
