No Longer Recognizing the Smell of Soap: A Signal Not to Ignore
Imagine this: you open your usual shower gel — the one you’ve used for years — and suddenly… nothing. Or perhaps only a faint scent that is difficult to recognize.
This seemingly trivial change could sometimes be an early sign of cognitive decline, according to Professor Davangere Devanand, a psychiatrist and neurologist at Columbia University in New York.
Why? Because the sense of smell is closely connected to memory. Early-stage Alzheimer’s disease can affect the brain regions responsible for identifying and processing scents.
🧠 When the Nose Knows Before the Mind
It may sound surprising, but our sense of smell can reveal what’s happening deep within the brain long before the more obvious symptoms of Alzheimer’s disease appear.
According to recent research, difficulty recognizing familiar scents — such as soap, coffee, or perfume — may be one of the earliest indicators of cognitive decline.
