Postural Sway Characteristics Distinguish Types of Dementia

The increasing number of patients with dementia necessitates the development of rapid and convenient tools to assist with dementia diagnosis. We previously demonstrated the difference in the postural control characteristics during static standing among Alzheimer disease (AD), dementia with Lewy bodies (DLB), and vascular dementia (VaD). In this study, we evaluated the classification accuracy of the postural sway test to assess its capacity to distinguish between types of dementia.
