The Smell Experience Project, a project of New York University’s Institute for Social and Psychiatric Initiatives—Education, Research and Services (InSPIRES) is collecting stories from people who have experienced a significant change in their sense of smell.

Changes in odor perception can be a symptom of a condition, such as depression, head injury, dementia, or allergies, or a side effect of medication. Because the changes are subjective and difficult to measure, medical professionals often do not ask patients about changes in their sense of smell. As a result, there is little documented information about these changes. Smell Experience Researchers need your help to better understand changes in our sense of smell.
