Cognitive Impairment in Senior Citizens Going Undetected in Primary Care
Study finds recommendations against routine screening leaving many dementia patients untreated
Feb. 13, 2012 - Brief cognitive screening of senior citizens by health care providers at routine care visits, combined
with further evaluation for those who failed, increased the new diagnoses of cognitive impairment two to three fold, according to a new study.
Such screening is counter to most recommendations that it should be done only when patients show symptoms.
The findings of this study run counter to the current standard recommendations by the American College of Physicians,
U.S. Preventive Health Task Force, and Alzheimer's Association, which discourage routine cognitive impairment/dementia screening on all older
patients at a certain age.
Screening is only recommended if a person comes to a provider with some type of complaint that could be due to dementia.
Researchers, led by Riley McCarten, MD, of the Minneapolis VA Health Care System and the University of Minnesota,
assessed the effect of screening on diagnosing cognitive impairment in patients who were seen in VA primary care clinics and had no indication
of memory loss.
Veterans aged 70 and older who failed the brief cognitive screen at a routine primary care visit were offered a further,
Of the 8,342 Veterans offered screening, 8,063 (97%) accepted, 2,081 (26%) failed the screen, and 580 (28%) agreed to
Among those accepting further evaluation, 93% were documented to have cognitive impairment, including 75% with dementia,
according to the report published in the Journal.of the American Geriatrics Society.
Additionally, 118 patients who passed the initial screen still requested further evaluation, and 87% were found to have
cognitive impairment, including 70% with dementia.
"Our study demonstrates that proactive strategies such as routine screening are well-accepted and effective in diagnosing
cognitive impairment, and that primary care providers value the diagnostic and management services involved," McCarten notes. "This project
has implications for strategies that seek to improve care and contain costs in dementia."
