More than half of people with PD overestimate how well they are able to smell. Loss of smell is one of the earliest symptoms of PD and among patients with PD, and nearly all patients with PD exhibit some loss of smell. Why is that a problem? Because loss of smell is one of the earliest signs of cognitive decline; Individuals with the poorest sense of smell at diagnosis are the most likely to develop dementia in the 10 years that follow.
In addition to being a risk factor for cognitive decline, loss of smell is a risk factor for malnutrition. People with hyposmia are more likely to have diminished appetite, early satiety, and weight loss.
In this course I'll explain why smell is affected in PD, show hyou how to test your sense of smell, and cover treatment options for smell retraining.
