Alzheimer’s and Dementia

Smell loss is thought to be linked to the onset of Alzheimer’s. If you are experiencing smell loss as a result of Alzheimer's, a Sentidos Smell Test Kit can help you identify what scents you are unable to detect and even help to recover them through smell training.

Sentidos Smell Loss Detection Test is a reliable and accurate test for anyone concerned about or experiencing a loss of olfactory function. It is a thoroughly tested and researched olfactory assessment. The test kit that includes 12 scented waxes, multiple choice answer sheet, and user instructions and is easily self-administered in 10-15 minutes.

Smell Loss and Alzheimer’s

Researchers have determined that "smell training", a practice that repeatedly exposes a patient to various smells in an effort to help improve their ability to detect scents, could help people regain their ability to detect scents.

"We also found that older people in particular were more likely to start to recover their sense of smell. And that the biggest improvements happened in those that had lost the most amount of smell function in the first place."

Smell Loss and Early-Stage Alzheimer’s

"The olfactory bulb—which sends smell information from the nose to the brain—is one of the first areas of the brain to sustain damage in Alzheimer’s disease. Brain areas that receive information from the olfactory bulb, such as the entorhinal cortex, are also affected early in the disease. As a result, impaired ability to recognize odors often occurs in people with early-stage Alzheimer’s before memory symptoms are noticed. Previous studies have suggested that individuals who scored poorly on smell tests were more likely to have had neurodegenerative changes in the brain caused by Alzheimer’s, such as a buildup of beta amyloid deposits, or plaques."
