Alzheimer’s Detection Tool: Clock Draw Test

The Clock Draw Test is a tool to detect early Alzheimer’s symptoms. The test can also help determine a person’s progression through the various stages of Alzheimer’s disease. While this test is a good indicator to determine whether or not a person may have Alzheimer’s, a proper screening for dementia and Alzheimer’s should be completed by a trained medical professional.

The fewer points a person scores on the test, the more likely he or she has Alzheimer’s or other dementia. For those without Alzheimer’s the test is very simple. In summary, a person is asked to draw a clock. The numbers and hands should be included on the clock. A specific time can be mentioned, to see if the person is able to properly position the hands of the clock on the clock face to match a given time. The test is scored by giving the person one point for completing different aspects of the test. A test that earns all four points will have a closed circle (1pt) with all twelve numbers (1pt) placed properly (1pt) and clock hands should be in the right place (1pt).
