The study involved 540 people, 18 to 95 years old, who had no history of neurological disease, memory problems or brain injury. It also included 139 people who had been diagnosed with Alzheimer's or mild cognitive impairment. All were given the TYM, the new test for Alzheimer’s, as well as two other commonly used cognitive tests, the mini-mental state examination and the Addenbrooke's cognitive examination-revised.
The TYM Alzheimer's test includes 10 tasks such as the ability to copy a sentence, the ability to determine word meanings, the ability to do calculations, and recall. An example of a TYM question might be to name four animals that begin with the letter “S”. Each task can earn the test-taker a maximum of 50 points. The TYM requires less time to do than the other tests. It identified 93 percent of those with Alzheimer's, whereas the mini-mental state examination identified only 52 percent of the people with Alzheimer's.
