BookLars P. Klimaschewski.
Summary: What happens in the brain when we are ageing? How does neuronal cell death occur when we become forgetful? Which new therapies are available to combat the death of brain cells? This non-fiction book informs those interested in neuroscience and medicine about the latest findings on the therapy of neurodegeneration with a focus on Alzheimer's dementia and Parkinson's disease. Supported by illustrative drawings, Lars P. Klimaschewski presents the latest developments in neurobiological research on ageing in a comprehensible way and reports exciting news from the Alzheimer's and Parkinson's laboratories worldwide. From the contents Introduction to brain development: Why do we need billions of nerve cells? What distinguishes our cerebral cortex from that of other mammals? - Ageing and neurodegenerative diseases: Why are nerve cells lost? The normal ageing process; B-synuclein: A key protein in Parkinson's disease; Dementia and Alzheimer's disease: The amyloid and tau pathology; Viral infections in neurodegenerative diseases: Does Covid-19 lead to neurodegeneration? - Saving or replacing nerve cells: Stem cell, immune or antisense therapies? The author Prof. Dr. med. Lars P. Klimaschewski is a professor at the Medical University of Innsbruck, head of the Institute of Neuroanatomy there and the author of numerous papers on neuronal degeneration and regeneration.
