Like all cognitive screening tests, it is designed to detect early brain changes to determine if an individual may be suffering from a form of dementia. The Mini-Mental State Examination (MMSE) 7 is the most widely applied test for dementia screening. Doctors diagnose Alzheimer’s and other types of dementia based on a careful medical history, a physical examination, laboratory tests, and the characteristic changes in thinking, day-to-day function and behavior associated with each type. There is no one test to determine if someone has dementia. It is often used in combination with other, more thorough screening tests, but even when used by itself, it can provide helpful insight into a person’s cognitive ability.

Scores on the MoCA range from zero to 30, with a score of 26 and higher generally considered normal. “The ability to draw the numbers of a clock and a particular time is an easy way to find out if a patient with high blood pressure has cognitive impairment,” said study author Dr Augusto Vicario of the Heart and Brain Unit, Cardiovascular Institute of Buenos Aires, Argentina. If the clock is drawn abnormally, for example if the numbers are in the wrong places, this indicates the possibility of dementia and a need for further evaluation by a qualified doctor. What does it mean if you draw a clock wrong? It was originally used to assess visuo-constructive abilities but we know that abnormal clock drawing occurs in other cognitive impairments.
