Mini-Cog
Administration:
- Say 3 nouns, e.g.
rock, apple, shoe. Ask the person to repeat the words.
- Instruct the
person to draw a clock by first drawing a circle, then adding numbers,
and then setting the time to show 8:20. Instructions can be
repeated and, if necessary, the subject can be told to draw a larger
circle. There are no additional instructions, and no time limit is
imposed. (Borson, 1999)
- Then ask the
person to repeat the 3 words.
Scoring and
Referral:
Either of the
following 2 conditions warrant referral to a physician for further
cognitive testing
- The person can
only recall one word
- The person cannot
draw the clock correctly
(see sample clock drawings in appendix of
Borson, 1999)
The MIni-Cog is a
tool for screening for dementia, and has been recommended for
use in inconjunction with the STEADI
Fall Risk Screening algorithm.
