@ayra Previous studies have shown a strong relationship between reduced odor detection and symptoms of depression, with less clear evidence of a link between olfactory perception and symptoms of anxiety, Cecchetto said. However, few studies have investigated to what extent individuals with symptoms of anxiety or depression are aware of, or pay attention to, odors in their environment, she added. The study included 429 healthy participants (76.9% women, aged 18 to 45 years) recruited through social media. The age cut-off was 45 because evidence shows that olfactory perceptions start to decline at that time of life, Cecchetto noted. Participants completed psychological questionnaires, including the Beck Depression Inventory-II, the Beck Anxiety Inventory, and the Liebowitz Social Anxiety Scale.
