A clock drawing test for detecting cognitive dysfunction should be conducted routinely in patients with high blood pressure according to latest research | European Society of Cardiology | via ScienceDaily

Patients with high blood pressure who have impaired cognitive function are at increased risk of developing dementia within five years. Despite this known link, cognitive function is not routinely measured in patients with high blood pressure. Research presented at the European Society of Cardiology Congress 2018 suggests the clock drawing test should be adopted as a routine screening tool for cognitive decline in patients with high blood pressure.

The Heart-Brain study evaluated the usefulness of the clock drawing test compared to the Mini-Mental State Examination (MMSE) to detect cognitive impairment.  For the clock drawing test, patients were given a piece of paper with a 10 cm diameter circle on it. They were asked to write the numbers of the clock in the correct position inside the circle and then draw hands on the clock indicating the time “twenty to four.”

The researchers found a higher prevalence of cognitive impairment with the clock drawing test (36%) compared to the MMSE (21%).
