About Us

The COGselftest mission is to promote early diagnosis of Alzheimer's Disease (AD) and Mild Cognitive Impairment (MCI) by making our clinical screening available in an easy-to-use, affordable, online format. By increasing public awareness of and exposure to early screening we will reduce the alarmingly high rate of those with AD and MCI who are going undiagnosed, and get them treated early, when treatments are most effective.
