Visual Association Test, MMSE Highly Predictive of Dementia in Older Adults

The 3-minute Visual Association Test (VAT), which tests associative memory, is a highly sensitive and valuable tool for detecting dementia risk in patients with a small decline on the 30-point Mini-Mental State Examination (MMSE), according to a study published in the Annals of Family Medicine.

Participants in the Prevention of Dementia by Intensive Vascular Care trial (age 70-78 years) were included in this study (n=2690). Investigators evaluated the change in MMSE score over a 2-year period as well as the VAT score at 2 years to determine whether these tests could predict dementia diagnosis in the following 4 to 6 years. Electronic health records provided information on dementia status at 2-year intervals.

The small sample size as a result of inclusion of only patients who were tested on the MMSE and VAT assessments at baseline and 2-year follow-up represents a limitation of this study.

Researchers concluded that the VAT “can help to distinguish those at increased risk of developing dementia (requiring counseling, additional examination, or both) from those in whom watchful waiting is justified.”
