This study demonstrates that recognition of cognitive impairment by primary care physicians is adversely influenced by important patient and disease characteristics. Results also show that use of the Mini-Cog would improve recognition of cognitive impairment in primary care, particularly in milder stages and in older adults subject to disparities in health care quality due to sociodemographic factors.

The Mini-Cog detects clinically significant cognitive impairment as well as or better than the MMSE in multiethnic elderly individuals, is easier to administer to non-English speakers, and is less biased by low education and literacy.

Mini-Cog screening by office staff is feasible in primary care practice and has measurable effects on physician behavior. However, new physician action relevant to dementia was likely to occur only when impairment was severe, and additional efforts are needed to help primary care physicians follow up appropriately on information suggesting cognitive impairment in older patients.

Background-Clock-drawing tests are popular components of dementia screens but no single scoring system has been universally accepted. We sought to identify an optimal subset of clock errors for dementia screening and compare them with three other systems representative of the existing wide variations in approach (Shulman, Mendez, Wolf-Klein), as well as with the CDT system used in the Mini-Cog, which combines clock drawing with delayed recall.

Prader-Willi syndrome is a multisystem neurogenetic obesity disorder with behavioral manifestations, including hyperphagia, compulsive behavior, self-injury, and mild to moderate mental retardation. In an 8-week open-label study, we evaluated adjunctive therapy with the anticonvulsant topiramate in 8 adults with Prader-Willi syndrome. Appetite was measured by a 1-hour access to food four times throughout the study and quantified with a visual analogue scale. Topiramate did not significantly change calories consumed, Body Mass Index, or increase self-reported appetite. In addition, there were no significant changes in compulsions. Surprisingly, topiramate treatment resulted in a clinically significant improvement in the self-injury (i.e., skin-picking) that is characteristic of this syndrome. Potential benefits of topiramate for self-injury should be evaluated further in controlled trials.
