The Role of Neuroimaging in Fall Prevention in Healthy Adults at Risk of Alzheimer's Disease

Abstract

Falls are an important clinical, socioeconomic, and public health problem in the older adult population. Advancing age is a major risk factor for mild cognitive impairment (MCI) and Alzheimer's disease (AD). The preclinical phase of AD, which is regarded as an important window for early therapeutic intervention before the onset of MCI and subsequently AD, can serve as a critical period to reduce or prevent falls among elderly people at risk of AD. In this chapter, first, a discussion is provided on the degrees of fall-related injuries, pain, and severity of falls in elderly people at risk of AD. Secondly, a discussion is provided on the clinical, socioeconomic, and public health implications of falls. Studies that integrated neuroimaging techniques were also reviewed to identify brain biomarkers that can be targeted for the prevention of falls among the elderly. It is anticipated that the outcome of this chapter may have a critical role in the prevention of falls among elderly people at risk or suffering from AD.
