New study links Alzheimer's disease to loss of smell

Tweet

A new study in the most recent issue of The Journal of Neuroscience finds a protein connected to Alzheimer's disease has the ability to kill nerve cells used by the body to detect odors.

The study, conducted on animals, provides new insight for senior citizens struggling with the disease and offers new hints on why victims of the disorder often lose their sense of smell while battling the disease.

"Deficits in odor detection and discrimination are among the earliest symptoms of Alzheimer's disease, suggesting that the sense of smell can potentially serve as a 'canary in the coal mine' for early diagnosis of the disease," said Dr. Leonardo Belluscio of the National Institute of Neurological Disorders and Stroke, who led the study.

Belluscio said the changes experienced by the olfactory system from Alzheimer's disease may be similar to changes experienced in other areas of the brain but happen more rapidly.

Senior citizens afflicted with any kind of serious health matter should be sure they are covered with a life insurance policy for the financial security of their dependents. According to the Senior Citizen Journal, term life insurance is a popular choice among the elderly because it doesn't require medical clearance for coverage.
