Voice Record­ings Spot Cog­ni­tive Impair­ment (Med­Page Today):

A machine-learn­ing mod­el iden­ti­fied mild cog­ni­tive impair­ment and demen­tia from dig­i­tal voice record­ings of neu­ropsy­cho­log­i­cal tests, an ear­ly study showed.

Among 1,084 peo­ple in the Fram­ing­ham Heart Study whose tests were record­ed, the aver­age area under the curve (AUC) reached 92.6% for dif­fer­en­ti­at­ing nor­mal cog­ni­tion from demen­tia, 88.0% for dis­cern­ing nor­mal cog­ni­tion or mild cog­ni­tive impair­ment from demen­tia, and 74.4% for dis­tin­guish­ing nor­mal cog­ni­tion from mild cog­ni­tive impair­ment.

Alzheimer’s Pre­dic­tion May Be Found in Writ­ing Tests (The New York Times):

… the researchers looked at a group of 80 men and women in their 80s — half had Alzheimer’s and the oth­ers did not. But, sev­en and a half years ear­li­er, all had been cog­ni­tive­ly nor­mal.
