Parkinson’s and Home Smell Test Kits

Although Parkinson’s is understood to be a disorder that mainly affects movement, most people with Parkinson’s experience smell loss. If you are experiencing smell loss as a result of Parkinson'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 includes 12 scented waxes, multiple choice answer sheet, and user instructions and is easily self-administered in 10-15 minutes.

Parkinson’s and Smell Loss

"Studies have shown that the pre-motor phase (the time before motor symptoms appear) lasts around five years or more and it has been estimated that in some cases smell loss may occur up to 10 years before Parkinson’s is diagnosed. It is during this pre-motor phase that early changes in the brain could potentially be detected if very early symptoms such as loss of the sense of smell were identified. It is therefore thought that screening, using reliable smell tests before typical motor symptoms are obvious, could help with the early detection of Parkinson’s or identifying those at higher risk of developing the condition."

Why Parkinson’s Causes Loss of Smell

Exactly why sense of smell is impaired in Parkinson’s is not completely understood. Many believe that it is related to the protein alpha-synuclein which clumps in the brain of everyone with Parkinson’s. These clumps have been found to occur in the area where smell is first processed in the brain (the olfactory bulb) as well as in the gastrointestinal system. In fact one study concluded that the olfactory bulb is where alpha-synuclein clumps first appear before migrating to other parts of the brain.

Parkinson’s and Home Smell Training

Impaired smell as a result of disease such as Parkinson’s and traumatic brain injury has also shown improvement in smell training trials.

 

"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 training via smell test kits can help the smell pathways to start to regenerate and recover. Throughout your smell training, Sentidos Smell Tests Kits can help track any improvements as they occur.
