For Physicians

The COGselftest evolved from the paper test created by Dr. John H. Dougherty Jr. in 2002. Ongoing studies of the online version of the test show it to be a very reliable and accurate tool for identifying cognitive impairment. The COGselftest monitors multiple domains, aiding in the detection of different types and degrees of cognitive impairment.

Domain-specific cognitive patterns shown in the test offer the possibility of detecting AD or MCI earlier and more efficiently. These patterns may also prove important in differentiating between AD and other types of dementias.

The COGselftest shows superior ability to discriminate between normal and AD groups, as well as between AD and MCI groups, as compared to the MMSE. The test showed a 95 percent accuracy rate in a random sample and a 93 percent accuracy rate in classifying AD/MCI groups.

Annual Wellness Visit
