An Early Sign of Alzheimer’s Disease Can Be Noticed While Taking a Shower: What Should You Look Out For?
🩺 What Studies Reveal
A major study conducted at Columbia University found that older adults with a reduced ability to identify common odors (such as soap, lemon, or cinnamon) were more likely to develop Alzheimer’s disease within the following five years.
Researchers believe that smell tests could become a simple, non-invasive, low-cost screening method for early Alzheimer’s risk. Unlike brain scans or lengthy cognitive exams, these tests can be done quickly — even at home — and may detect changes long before memory loss becomes apparent.
💡 What You Can Do If You Notice a Change
A sudden difficulty recognizing familiar scents doesn’t automatically mean Alzheimer’s, but it’s important to take it seriously. Here’s what you can do:
Rule out simple causes — A sinus infection, nasal polyps, or even COVID-19 can cause temporary smell loss.
Track how long it lasts — If the problem persists for weeks or months without explanation, consult a doctor.
Ask for an evaluation — A neurologist can perform smell identification tests and cognitive assessments.
Adopt brain-healthy habits — Regular exercise, mental stimulation, quality sleep, and a Mediterranean-style diet rich in antioxidants are linked to a lower risk of cognitive decline.
Engage your senses — Smelling herbs, spices, or essential oils regularly may help keep the olfactory system active.
🧠 Prevention Starts with Awareness
The next time you take a shower, don’t just focus on getting clean — take a moment to notice what you smell. The simple act of recognizing whether your favorite soap still smells the same can be a surprisingly powerful way to keep track of your brain health.
Alzheimer’s disease doesn’t appear overnight. It begins with subtle, often overlooked changes — and sometimes, your nose may notice them long before your memory does.
