Sim­ple scratch and sniff tests could help de­tect peo­ple with the early stages of Alzheimer’s dis­ease. A Cana­dian study of al­most 300 peo­ple aged 60-plus with a fam­ily his­tory of Alzheimer’s found those who had prob­lems iden­ti­fy­ing smells such as bub­blegum, petrol and lemon had higher amounts of Alzheimer’s-re­lated pro­teins in their spinal fluid. The re­searchers say it may be pos­si­ble to de­velop a smell test to track the pro­gres­sion of the dis­ease.
