A Subtle Early Sign of Alzheimer’s You Might Notice in the Shower
It’s often assumed that the first signs of Alzheimer’s disease are related to memory—forgetting names, struggling to find words, or getting lost in familiar places. While these are common symptoms, research suggests that much earlier and more subtle changes may occur.
One surprising early signal? A reduced ability to recognize familiar smells—even something as simple as your usual soap.
Losing Your Sense of Smell: A Sign Worth Noticing
Imagine opening a shower gel you’ve used for years and suddenly finding the scent faint, unfamiliar, or hard to identify. This change might seem minor, but it could be meaningful.
According to Davangere Devanand of Columbia University, the sense of smell is closely linked to memory and brain function.
In early Alzheimer’s disease, the brain regions responsible for processing odors are among the first to be affected. This can lead to difficulty identifying or distinguishing smells long before noticeable memory loss begins.
A Simple but Revealing Test
A Simple but Revealing TestIn a long-term study involving over 1,000 participants, researchers used a basic smell identification test. Participants were asked to recognize common scents such as:
Soap
Smoke
Rose
Leather
The findings were significant: individuals who struggled to correctly identify these odors were more likely to develop cognitive impairment later.
A score below 8 out of 12 was considered a potential warning sign. When combined with short memory assessments, this simple smell test proved nearly as informative as more complex tools like brain imaging in some cases.
