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 and a report from Neurology Advisor.

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.

A reduction in the total MMSE score of 2 points over a 2-year period was associated with increased odds for developing dementia, according to the logistic regression analysis (odds ratio 3.55; 95% CI, 2.51-5.00).
