King-Devick Test Accurately Screens Mild Cognitive Impairment, Dementia and Alzheimer’s
Did you know that all it takes is a simple number naming test to differentiate between someone who is cognitively healthy, has mild cognitive impairment or is suffering from a degenerative brain disease like Dementia or Alzheimer’s?
A study published in the journal Alzheimer’s Disease and Associated Disorders called “Screening Utility of the King-Devick Test in Mild Cognitive Impairment and Alzheimer Disease Dementia” has given evidence for health care providers to use the King Devick as another means to test brain patients who might benefit from a more thorough examination.

Diagnosis of Alzheimer’s Disease
Truth is that current diagnosis of Alzheimer’s disease isn’t as easy as many would think. With our current medical knowledge and technologies, a definite diagnosis can only happen when the patients brain is examined after death.
Recent medical advances have allowed doctors to produce tests that more accurately diagnose Alzheimer’s; however, these tests are often expensive and invasive to the patient (a spinal tap isn’t very fun).
It was necessary for medical researchers to find a different way to screen people who needed such procedures and who didn’t.
King Devick Baseline Test
Researchers from Harvard Medical School, New York University School of Medicine and Boston University Alzheimer’s Disease Centre teamed up to determine if the King Devick (K-D), a test used to diagnose and quantify the level of cognitive decline in concussion patients and those with other neurological diseases, would also work for Alzheimer’s.
The benefits of using such a test for Alzheimer’s and cognitive decline diagnosis were apparent:
- it’s simple and straightforward
- can be administered by non-medical office staff
- is completed within a matter of minutes
The test also exists in both paper and electronic form, giving options to more traditional patients as well as younger, more technologically inclined patients.
- 206 individuals participated in the experiment
- 32 were suffering from Alzheimer’s dementia
- 39 had some form of mild cognitive impairment
- 135 were cognitively healthy
King Devick’s number test managed to place participants in the correct group 90 percent of the time and was accurate in detecting both mild and severe cognitive impairments. These results, when compared with those done by more advanced neurophysiological tests, correlated surprisingly well.
According to Robert Stern, a neurology professor and director of the Clinical Core of the Alzheimer’s Disease Centre, the King Devick Baseline’s number test is a good tool to use to determine the level of cognitive decline in patients who need it.
Because Alzheimer’s is often underdiagnosed and hard to detect, and the changes in the brain that result in the degenerative condition could begin up to 20 years before clinical symptoms, having a screening test like the King Devick can help people begin preventative treatments well before hand.
There is a gross need for the health profession to be able to detect Alzheimer’s disease in it’s early stages, especially as new advances in medicine become available to help treat such degenerative conditions.
