Loss of Smell

Not all people with reduced sense of smell will go on to develop Parkinson’s, but most people with PD have some loss of their sense of smell.

In fact, reduced sense of smell, called hyposmia, is often an early sign of Parkinson’s. Looking back, you may realize you were losing your sense of smell several years before you received a Parkinson’s diagnosis.

Hyposmia is an under-recognized symptom, as it is not a common concern for doctors to ask about or for patients to report. If you or someone you know has trouble smelling foods like bananas, dill pickles or licorice, ask your doctor about Parkinson’s.

Managing Loss of Smell

There are not any treatments for lost sense of smell. However, reduced ability to smell might affect your appetite, since taste is linked to smell. If you find yourself gaining or losing weight, learn more about diet and nutrition and call our Helpline for tips: 1-800-4PD-INFO (473-4636).
