This study aimed to explore factors associated with clinical evaluations for cognitive impairment among older residents of the United States.

Vikas Kotagal, MD, MS, of the University of Michigan in Ann Arbor, Mich., and colleagues found that of the 297 participants with dementia in ADAMS, 55.2% (representing about 1.8 million elderly Americans in 2002) reported no history of a clinical cognitive evaluation by a physician. In a multivariable logistic regression model (n = 297) controlling for demographics, physical function measures, and dementia severity, marital status (odds ratio for currently married: 2.63 [95% confidence interval: 1.10–6.35]) was the only significant independent predictor of receiving a clinical cognitive evaluation among subjects with study-confirmed dementia.
