Scott examines the bidirectional relationship between depression and sense of smell, exploring potential mechanisms and treatment implications. Longer summary

This post discusses the relationship between depression and olfactory function.

The post explores potential reasons for this connection, including depression's general effect on sensory acuity and the unique emotional salience of smell. It also discusses implications for depression treatment, including the effects of antidepressants on smell and potential olfactory-based therapies. The tone is analytical and somewhat humorous, with Scott critically examining various studies and hypotheses. Shorter summary
