The BOMC is a screening tool allowing family members, caregivers, or health care professionals to check for suspected dementia in an elderly.

Dementia is described as the progressive loss of memory and at least of one other cognitive area, such as language or behavior.

Scoring BOMC



·The scores from each of the six items are multiplied to yield a weighted score.


·Score “1” for each incorrect response.


·Scoring items 4. and 5.: For uncorrected errors, score “2”; for self-corrected errors, score “1”. For no errors, score “0”.


·Scoring the memory phrase: If no cue is necessary and the patient recalls both name and address, score “0”. If the patient cannot spontaneously recall the name and address, cue with “John Brown” one time only. If this cue is necessary, the patient automatically has 2 errors.


•Score 1 point for each subsequent “unit” the patient cannot recall.





Score 0 – 9

The score for this test does not reveal signs related to dementia or cognitive impairment. If despite this low scoring lately you observed changes in the cognitive functioning and behavior in an elderly loved one, DYSmd™ suggests you also administer the Mini-Mental State Exam (MMSE). The MMSE will help further investigate the current condition. Please make sure to discuss your observations with the primary care doctor of the person affected. The MMSE can be found by choosing the category Geriatrics in the DYSmd™ quiz search function.




Score 10 – 28

The score for this test reveals signs related to dementia or cognitive impairment. It is important that the person affected be evaluated by his or her primary care doctor and you discuss this test and your latest observations. If you find yourself without easy access to a health care provider, there are organizations offering help.  The American Medical Association: or the American Board of Family Medicine:
