You can test a patient for Alzheimer by asking them to draw the face of a clock!

The Clock drawing test is a brief cognitive task that can be used by physicians who suspect neurological dysfunction based on history and physical examination.

It is relatively easy to train non-professional staff to administer a CDT.Therefore, this is a test that can easily be administered in educational and geriatric settings and can be utilized as a precursory measure to indicate the likelihood of further/future deficits.

It also helps the physician as a screening tool for Alzheimer’s and other types of dementia.The procedure of the CDT begins with the instruction to the participant to draw a clock reading a specific time (generally 11:10).

After the task is complete, the test administrator draws a clock with the hands set at the same specific time. Then the patient is asked to copy the image.Memory, concentration, initiation, energy, mental clarity and indecision are all measures that are scored during this activity.
