One word test for dementia

 Have at it.  You might want to practice this before seeing your doctor

The “WORLD” test. The first test is to ask a patient to spell the word “world” forward and backward and then list the letters in “world” in alphabetical order. This test is scored as wholly correct or incorrect and has been found to have a sensitivity of 85 percent and a specificity of 88 percent for AD.¹¹ Leopold and Borson assert that that when a highly educated patient fails this test, a strong suggestion of impaired cognition is made and more formal testing should be carried out.¹¹.
