American Journal of Alzheimer’s Disease &Other Dementias®, Ahead of Print.
Objectives:This study examined the efficacy of the General Practitioner Assessment of Cognition–Chinese version (GPCOG-C) in screening dementia and mild cognitive impairment (MCI) among older Chinese.Methods:Survey questionnaires were administered to 293 participants aged 80 or above from a university hospital in mainland China. Alzheimer disease and MCI were diagnosed in light of the National Institute on Aging and the Alzheimer’s Association (NIA/AA) criteria. The sensitivity and specificity of GPCOG-C and Mini-Mental State Examination (MMSE) in screening dementia and MCI were compared to the NIA/AA criteria.Results:The GPCOG-C had the sensitivity of 62.3% and specificity of 84.6% in screening MCI, which had comparable efficacy as the NIA/AA criteria. In screening dementia, GPCOG-C had a lower sensitivity (63.7%) than the MMSE and a higher specificity (82.6%) higher than the MMSE.Conclusions:The GPCOG-C is a useful and efficient tool to identify dementia and MCI in older Chinese in outpatient clinical settings.The Efficacy of General Practitioner Assessment of Cognition in Chinese Elders Aged 80 and OlderThe Efficacy of General Practitioner Assessment of Cognition in Chinese Elders Aged 80 and OlderAlzheimers{$excerpt:n}
