Recognizing the need for an easily accessible test for every user, we’ve developed the COGselftest to give your physician the tools to catch early signs of dementia and cognitive impairment in people ages 50 and older. Be sure to ask your physician if you are concerned about your memory.

The COGselftest evolved from the paper self-test created by Dr. John H. Dougherty Jr. in 2002. More than 1500 trials of the paper test have been conducted, and studies of the online version of the test show it to be a reliable tool, not only for identifying cognitive impairment, but also for zeroing in on the specific areas that need improvement.

It is our hope that by making this online version of the test accessible to more physicians, we can begin to reduce the number of people who fall through the diagnostic cracks until it is too late for effective treatment.

This test is quick (about 10 minutes), easy to take and reliable. It looks at the six major areas, or cognitive domains, that are likely to be impaired by dementia.

Cognitive domains

  • Orientation: The awareness of time, place, situation and self
  • Visuospatial Organization: The ability to visualize, organize, manipulate and recreate objects
  • Verbal fluency: The ability to quickly and accurately use language
  • Working Memory: The ability to recall information and previous experiences as well as to learn and store new information
  • Attention: The ability to concentrate and focus on information without being easily distracted
  • Executive functions: The ability to reason and make decisions and judgments

By assessing the skills in each area, the COGselftest can help you and your doctor identify areas that may need attention and help you monitor changes and improvements.
