Objective Due to the increasing elderly population and number of dementia patients, the current number of psychiatrists and neurologists remains insufficient to treat dementia in Japan. Therefore, a simple method for accurately performing a dementia diagnosis, including that of primary care physicians, is sought in clinical practice. Methods A retrospective study was conducted on patients who made their first visit due to amnesia between October 2020 and October 2022. ⋯ Comparing Alzheimer's disease (AD) and dementia with Lewy bodies (DLB), the difference between the MMSE and CDT scores was significantly greater in patients with DLB. Conclusion To quickly screen for dementia, a combination of CCT and CDT is recommended for the highest sensitivity (78.4%). In addition, the difference between the CDT and MMSE scores is considered to be useful for differentiating DLB from AD.
