Description

<p>Neuropsychological tests are one of the most important parts of assessments of dementia. Recently, neuropsychological tests have been used to assess one or more cognitive domains in people with dementia, as described in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition （DSM-5）. In other words, neuropsychological tests should be used as tools for evaluating multiple cognitive domains in more detail and not only as screening tests for diagnosis. Although the cut-off points of screening tests （e.g., the Mini-Mental State Examination or the Revised version of Hasegawa’s Dementia Scale） provide valuable information for diagnosis, the responses to each item for testing contain additional information about declined or intact cognitive domains. Using multicomponent and standardized neuropsychological tests （e.g., Wechsler Adult Intelligence Scale or COGNISTAT）, we can access the individual data more accurately and objectively. In addition, these data contribute to clinical care decisions for people with dementia. For instance, in memory tasks, people who completed the cued recall or recognition tasks may resolve their difficulties in daily living with appropriate support, although they fail the free recall. Thus, the results of neuropsychological test scores can be translated into valuable information for clinical care, and they should not only be treated as test scores. For maximizing the benefits for people with dementia, systems that communicate the meanings of neuropsychological tests are highly required.</p>
