Imagine this: you open your usual shower gel, the one you’ve used for years, and suddenly… nothing. Or rather, a faint, difficult-to-identify scent. This seemingly trivial change could be one of the early signs 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 linked to memory. Early-stage Alzheimer’s disease affects the regions of the brain responsible for identifying and processing scents.
