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.

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.

Our sense of smell is directly connected to the olfactory bulb, which is closely linked to the hippocampus and amygdala — areas of the brain responsible for memory and emotions.
These regions are often among the first affected by Alzheimer’s disease.
