Neuroimaging in dementias

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Late onset dementia is usually a multifactorial disease wherein cumulative pathological brain insults (of more than one pathology) result in progressive cognitive decline which ultimately leads to impairment in one’s ability to perform usual activities of daily living. Until recently, postmortem examination has been the only way to accurately determine the underlying pathology that led to dementia. However with the recent emergence of advanced imaging technologies, imaging indicators of disease that closely reflect the underlying pathology have been found to be very useful in aiding the prediction of the underlying dementia pathology. In this chapter, we will cover the cerebrovascular disease and the three common neurodegenerative dementias-Alzheimer’s disease, dementia with Lewy bodies, and frontotemporal dementia. For each of these contributors to dementia, we will discuss the clinical manifestation of the disease, the pathologies underlying the disease, and the neuroimaging correlates that can be observed using the currently available imaging methods.
