Alzheimer’s disease slowly erodes your sense of smell up to twenty years before memory loss begins. This means Alzheimer’s can be detected before it impairs your quality of life. 

In a recent study, 97% of patients who could not smell peppermint, fish, orange, leather and roses developed Alzheimer’s disease five years later. 

We used this insight to create an early warning system against dementia.

Dementia Highlighters are a set of smelly pens distributed alongside Sudoku’s, crosswords and other brain teasers.
