Alzheimer’s could be diagnosed early with sniff tests !

Alzheimer’s disease is an irreversible condition characterized by memory loss and damage of other cognitive functions. At present, there are no effective ways of diagnosing progression toward Alzheimer’s early on in populations that are at risk.

Diagnoses usually follow from the identification of mild cognitive impairment, but this may not be early enough for treatments to be significantly effective.
