How accurate is the clock test for dementia?

Previous studies of objective clock drawing test rating systems identified Alzheimer's disease with overall diagnostic accuracy ranging from 59% to 85%. However, such diagnostic accuracy has not been found in mild cognitive impairment cohorts with sensitivities ranging from 17% to 92%.

How do you do the clock-drawing test?

To perform the test, the clinician asks the patient to register three unrelated words (e.g., banana, sunrise, and chair) and then asks him or her to draw a clock, stating, “Draw a large circle, fill in the numbers on a clock face, and set the hands at 8:20.” The patient is allowed 3 minutes to draw the clock, and ...

What is the 6 item cognitive impairment test?

What does it mean when someone draws a clock with all the numbers on one side?

The usual striking example is when a clock drawing has all the numbers on one half of the clock but not the other half. In this case, the clock-drawing test can be used to reveal neglect, but is not diagnostic. Neglect can commonly be seen in individuals with stroke.

How do you stop dementia from progressing?

Is the clock test accurate?

In conclusion, studies which tested the accuracy of the CDT in dementia screening have shown that the CDT may be scored reliably with a variety of scales and that it accurately discriminates cognitively unimpaired patients from patients showing early cognitive decline.

How accurate is the clock-drawing test?

How is severity of dementia assessed?

MMSE: This test is graded by severity and has been used extensively in memory clinics to measure response to medication and guide decisions: 20-26 = mild cognitive impairment; 10-20 = moderate impairment; and less than 10 indicates severe impairment. ACE III: This is a much more detailed test, scored out of 100.
