To examine the impact of the revised diagnostic criteria for neurocognitive disorders (NCDs) in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) on the prevalence of dementia and mild cognitive impairment (MCI).
A total of 755 participants aged 65 years or older in the Nationwide Survey on Dementia Epidemiology in Korea 2012 were rediagnosed according to the DSM-5 criteria.
The estimated age-, gender-, education-, and urbanicity-standardized prevalence rates of major and mild NCDs were 8.35 and 11.10%, respectively, and those of dementia and MCI were 8.74 and 31.85%, respectively. Cohen's κ for dementia and major NCD was 0.988, and that for MCI and mild NCD was 0.273.
Diagnostic discrepancies between major/mild NCDs and dementia/MCI might depend on the operationalization of neuropsychological performance criteria.
探讨《精神疾病诊断与统计手册》第5版（DSM-5）中神经认知障碍（NCDs）修订诊断标准对痴呆症和轻度认知障碍（MCI）患病率的影响。
根据DSM-5标准，对2012年韩国全国痴呆症流行病学调查中755名65岁及以上参与者进行重新诊断。
主要和轻度NCDs的年龄、性别、教育程度和城市化程度标准化患病率估计分别为8.35%和11.10%，痴呆症和MCI的患病率分别为8.74%和31.85%。痴呆症和主要NCD的Cohen's κ为0.988，MCI和轻度NCD的Cohen's κ为0.273。
主要/轻度NCDs与痴呆症/MCI之间的诊断差异可能取决于神经心理表现标准的操作化。
