Background: As the Asian population continues to age, significant concerns regarding increases in dementia have arisen. Dementia rates are expected to dramatically increase by 2025, and early identification of those with dementia will be critical. Unfortunately, throughout Asia the elderly have exceedingly limited accessibility to clinicians who have the ability to conduct cognitive assessments. Fortunately, the emergence of digitized cognitive testing technology has the potential to benefit a wide range of patients who have previously had limited access to neuropsychological assessment. Methods: 327 subjects in China were recruited from a major hospital in Shanghai as well as from two community sites in surrounding areas. Subjects were independently diagnosed with mild dementia of the Alzheimer’s type or mild cognitive impairment. All subjects were tested in their native language using the Savonix health assessment tool that delivers a set of digitized neurocognitive tests via Android and iOS mobile operating systems and is supported by a web-based client dashboard for data tracking and analytics. Results: Classification rates of 63.64% 81.19% correct, and sensitivity and specificity scores ranging from 0.59 to 0.90 were obtained. Conclusions: Novel mobile digital cognitive screening tools can provide validmeasurements of cognitive health and are sensitive enough to differentiate two related patient populations. The present study provides support to using a mobile cognitive screening app as a screening measure for cognitive impairment. This new technology will hopefully facilitate cognitive assessments for those in remote areas or for those who lack affordable access to clinicians trained in cognitive assessment. Furthermore, earlier detection of dementia could either delay the onset of dementia or slow its progression by one or two years, thus reducing the global burden of dementia.
