Olfactory Training in Mild Cognitive Impairment

Sense of smell tends to decline in individuals with early Alzheimer's disease, typically earlier than when other senses and thinking abilities begin to decline. Memory for new odors is particularly diminished in these individuals. Existing treatments for AD do not improve these symptoms. A targeted treatment for improving sense of smell, called 'Olfactory Training', has been used to improve sense of smell in people with various forms of smell loss, though it is not known whether it can improve smell abilities and thinking abilities in patients who are at high risk of developing Alzheimer's disease. The investigators will conduct a randomized clinical trial with patients who have mild cognitive impairment (MCI). This is an early phase of memory loss that is worse than normal aging and may precede Alzheimer's disease. Patients will be randomized to either olfactory memory training or visual memory training for 3 months, with a final follow-up visit at 6 months. This study will attempt to determine if olfactory training is a useful for improving smell abilities, thinking abilities, and everyday functioning by examining change in these outcomes over time.
