Loss of Smell May Indicate Early Alzheimer's

A new study indicates that Alzheimer's disease can cause brain immune cells to mistakenly target healthy nerve fibers responsible for the sense of smell. Approximately 85% of individuals with Alzheimer's disease experience at least some reduction in their sense of smell. Dr. Del Bredesen of the Pacific Neuroscience Institute advises individuals with olfactory concerns to seek testing. The research suggests loss of smell may serve as an early indicator of the condition. Patients with concerns regarding cognitive health are advised to undergo testing. Testing is recommended for those with concerns regarding neurological health. Dale Bredesen states that individuals should undergo testing if they experience a loss of smell. Individuals concerned about neurological health should seek testing. Experts recommend testing for Alzheimer's if concerns about smell loss arise.
