Neurobiology of Aging: Exploring Cognitive Decline and Neurodegeneration is a comprehensive reference exploring the complexities of the aging brain. This book examines the intricate processes driving cognitive decline and neurodegeneration. From the gradual loss of neurons and synapses to the formation of protein aggregates characteristic of Alzheimer's disease, each chapter reviews key aspects of brain aging. Chapters dissect the mechanisms driving neuronal loss, synaptic dysfunction, and protein misfolding, shedding light on the intricate interplay of oxidative stress, inflammation, and mitochondrial dysfunction. This book also navigates through strategies for healthy brain aging, from the impact of diet and exercise to the role of cognitive stimulation.
