This book covers the most advanced practices and techniques in early differential diagnosis, assessment, and treatment of cortical dementias, and is intended to advance clinical skills of professionals and trainees alike. It focuses on cortical dementias as opposed to also discussing subcortical dementias. The book discusses the foundations of neuropsychology in the assessment, diagnosis, and treatment of cortical dementias. Individual dementing processes are discussed in detail, from traditional presentations such as Alzheimer’s disease and Lewy body dementia to less commonly discussed entities such as primary progressive aphasia (PPA) and chronic traumatic encephalopathy. Advances in neuroimaging and the utilization of biomarkers in early detection are discussed. Additional chapters are dedicated to related topics including the role of caregivers and determination of capacity. The book is divided into three sections. Section I describes the neuropsychological, neuroanatomical, and neurophysiological features of several of the more common cortical dementias, provides a brief guide to the main brain imaging techniques and a quick look at future directions in neuroimaging, and presents an overview of the differential diagnostics techniques such as Mini-Mental State Examination (MMSE) and Clinical Dementia Rating scale (CDR). Section II covers the types of cortical dementias such as vascular dementias, dysexecutive impairment associated with vascular dementias, neurophysiological disturbances and frontotemporal dementia. The third section talks about interventions, pharmacological interventions including galantamine and memantine, non-pharmacological cognitive, the role played by caregivers, comorbidities, and some legal and ethical considerations.
