“…However, the changes introduced in the DSM-5 may result in significant differences in the prevalence estimate of major NCD from that of dementia, since amnestic disorders and/or rare types of dementing illnesses are more prevalent in clinical populations than in randomly sampled community populations. In fact, a previous study performed in a memory clinic reported that about 19% of the patients with MCI were reclassified as having major NCD due to the presence of impairment in only a single cognitive domain and a lack of memory impairment in 30% of the patients [8]. …”

“…Studies on the impact of these diagnostic parameter changes on the prevalence of dementia and MCI are needed. In 1 clinical study, 78.2% of the patients met the diagnostic criteria for major NCD; however, only 56.0% met the diagnostic criteria for dementia [8]. However, the prevalence of major NCD versus that of dementia has never been studied in a community sample.…”

Aim: 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). Methods: 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. Results: 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. Conclusion: Diagnostic discrepancies between major/mild NCDs and dementia/MCI might depend on the operationalization of neuropsychological performance criteria.

Background There are only a few studies of the prevalence of dementia in people with intellectual disability (ID) without Down syndrome (DS), and there is a large difference in the prevalences between reported studies. Moreover, the prevalence of mild cognitive impairment (MCI) in ID has not been reported. We aimed to evaluate the prevalence of dementia in adults of all ages and the prevalence of MCI in people with ID. Furthermore, we tried to clarify the differences depending on the various diagnostic criteria. Methods The survey included 493 adults with ID at 28 facilities in Japan. The caregivers answered a questionnaire, and physicians directly examined the participants who were suspected of cognitive decline. Dementia and MCI were diagnosed according to ICD‐10, DC‐LD, and DSM‐5 criteria. Results The prevalence of dementia was 0.8% for the 45 to 54 years old group, 3.5% for the 55 to 64 years old group, and 13.9% for the 65 to 74 years old group in people with ID without DS. The prevalence of MCI was 3.1% for patients 45 to 54, 3.5% for patients 55 to 64, and 2.8% for patients 65 to 74 with ID without DS. DSM‐5 was the most inclusive in diagnosing dementia and MCI in people with ID. Conclusions People with ID without DS may develop dementia and MCI at an earlier age and higher rate than the general population. Among the diagnostic criteria, DSM‐5 was the most useful for diagnosing their cognitive impairment.
