Hypothalamus And Neuropsychiatric Neurodegenerative And Other Disorders

The Human Hypothalamus: Neuropsychiatric Disorders, Volume 181 in the Handbook of Clinical Neurology series, provides comprehensive summaries of recent research on the brain and nervous system as they relate to clinical neurology. This volume identifies the neurobiology and neurophysiology of disorders relating to the hypothalamus and provides treatment information for these disorders. Disorders covered include neuropsychiatric, neurodegenerative, periodic, and autoimmune disorders. Coverage includes Alzheimer’s, Parkinson’s, epilepsy, sleep, pain, depression, anxiety, OCD, PTSD, schizophrenia, autism, aggressions, addiction, and more. Summarizes research on how the hypothalamus relates to neurological disorders Contains neuropsychiatric, neurodegenerative, periodic and autonomic disorders Includes the neurobiology of, and treatment for, each disorder Covers depression, anxiety, OCD, PTSD, schizophrenia, autism, aggression, addiction, and more Provides coverage of sleep and pain

The human hypothalamus, a small structure at the base of the brain, has strategic importance for the harmonic function of the human body. It controls the autonomic nervous system, neuroendocrine function, circadian and circannual rhythms, somatic activities, and behavior, and is situated at the borders between the brain and the body and the brain and the soul, meeting points for mind and body. The hypothalamus is involved in a wide range of higher mental functions, including attention, learning and reinforcement of mnemonic processes, emotional control, mood stability, and cognitive-emotional interactions. It also has a role to play in behavioral disorders, panic reactions, cluster headache, gelastic epilepsy, mental deficiency, periodic disorders, depression, autism, and schizophrenia, and in a substantial number of neurodegenerative diseases. It enlarges greatly the dimensions of the hypothalamic contribution in controlling psychosomatic equilibrium and retaining internal unity of the human existence.

The Hypothalamus is an important area of the brain for understanding a variety of neurological disorders. This volume summarizes for readers the anatomy and physiology of the anterior hypothalamus, to better understand pathology and treatment of hypothalamus related disorders. In addition to anatomy and physiology in humans, cytoarchitecture and chemoarchitecture in rodents is provided. The volume explores the role of the hypothalamus in disorders of eating, sleeping, anxiety, and mood, as well as its role in sexual behavior and gender identity. Coverage includes how Parkinson’s, Alzheimer’s and other neurological disorders relate to the hypothalamus. Reviews the anatomy and physiology of the anterior hypothalamus Provides cytoarchitecture and chemoarchitecture from rodents Discusses hypothalamic related disorders of eating, sleeping, anxiety, and mood Covers how Parkinson’s, Alzheimer’s and other neurological disorders relate to the hypothalamus Explores the role of the hypothalamus in sexual behavior and gender identity

This book focuses on the exciting recent progress in restorative neurology and neuroscience. The book includes chapters on major neurodegenerative disorders of the brain and the visual system, including Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis, Huntington's disease, macular degeneration, retinitis pigmentosa, glaucoma, spinal cord trauma, and multiple sclerosis. The primary goal of the book is to give an overview of new developments in translational research and in potential therapeutic strategies, including stem cell therapy, immunotherapy, gene therapy, pharmacotherapy, neuroprostheses and deep brain stimulation. * Provides the reader with a unique overview over all aspects of new advances in the therapy of neurological and psychiatric disorders * Covers all levels of biological organization including novel molecular and cellular targets, electrophysiological, anatomical and behavioural substrates of neurodegeneration and the application of whole brain in vivo imaging * Broad focus with contributions by the top scientists worldwide in the respective disciplines

This e-book focuses primarily on the role of the fornix as a functional, prognostic, and diagnostic marker of Alzheimer’s disease (AD), and the application of such a marker in clinical practice. Researchers have long been focused on the cortical pathology of AD, since the most important pathologic features are the senile plaques found in the cortex, and the neurofibrillary tangles and neuronal loss that start from the entorhinal cortex and the hippocampus. In addition to gray matter structures, histopathological studies indicate that the white matter is also altered in AD. The fornix is a white matter bundle that constitutes a core element of the limbic circuits, and is one of the most important anatomical structures related to memory. The fornices originate from the bilateral hippocampi, merge at the midline of the brain, again divide into the left and right side, and then into the precommissural and the postcommissural fibers, and terminate at the septal nuclei, nucleus accumbens (precommissural fornix), and hypothalamus (postcommissural fornix). These functional and anatomical features of the fornix have naturally captured researchers’ attention as possible diagnostic and prognostic markers of AD. Growing evidence indicates that the alterations seen in the fornix are potentially a good marker with which to predict future conversion from mild cognitive impairment to AD, and even from a cognitively normal state to AD. The degree of alteration is correlated with the degree of memory impairment, indicating the potential for the use of the fornix as a functional marker. Moreover, there have been attempts to stimulate the fornix to recover the cognitive function lost with AD. Our goal is to provide information about the status of current research and to facilitate further scientific and clinical advancement in this topic.

Collectively, neurodegenerative diseases are characterized by chronic and progressive loss of neurons in discrete areas of the brain, producing debilitating symptoms such as dementia, loss of memory, loss of sensory or motor capability, decreased overall quality of life eventually leading to premature death. Two types of cell death are known to occur during neurodegeneration: (a) apoptosis and (b) necrosis. The necrosis is characterized by the passive cell swelling, intense mitochondrial damage with rapid loss of ATP, alterations in neural membrane permeability, high calcium influx, and disruption of ion homeostasis. This type of cell death leads to membrane lysis and release of intracellular components that induce inflammatory reactions. Necrotic cell death normally occurs at the core of injury site. In contrast, apoptosis is an active process in which caspases (a group of endoproteases with specificity for aspartate residues in protein) are stimulated. Apoptotic cell death is accompanied by cell shrinkage, dynamic membrane blebbing, chromatin condensation, DNA laddering, loss of phospholipids asymmetry, low ATP levels, and mild calcium overload. This type of cell death normally occurs in penumbral region at the ischemic injury site and in different regions in various neurodegenerative diseases.
