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.
Leading researchers offer cutting-edge information on glutamate metabolism in the brain, examining the role of glutamate transporters and the involvement of glutamate receptors in the pathogenesis of acute neural trauma and neurodegenerative diseases. In addition, the authors discuss the treatment of these diseases with endogenous and exogenous antioxidants and glutamate receptor antagonists.
Considerable progress has been made in neurochemical and therapeutic aspects of dementia research in recent years. Molecular and Therapeutic Aspects of Dementia presents readers with comprehensive and cutting-edge information on the neurochemical mechanisms of various types of dementias. It provides a clearly written and logically organized and comprehensive overview of molecular aspects of risk factors, symptoms, pathogenesis, biomarkers, and therapeutic strategies for various types of dementia. This book is written for the international audience of neurochemists, neuroscientists, neurologists, neuropharmacologists, and clinicians. The hope is that this discussion will not only integrate and consolidate knowledge in this field, but will jumpstart more studies on molecular mechanisms and therapeutic aspects of dementia. The comprehensive information in this monograph may not only help in early detection of various types of dementia and dementia linked neurological disorders, but also promote discovery of new drugs, which may block or delay the onset of dementia in elderly patients. Understanding the course of dementia is important not only for patients, caregivers, and health professionals, but also for health policy-makers, who have to plan for national resources needed in the management of an increasing number of dementia cases. Provides a comprehensive overview of molecular aspects of risk factors, symptoms, pathogenesis, biomarkers, and therapeutic strategies for various types of dementia Summarizes cutting edge research information on signal transduction processes associated with neurochemistry of dementia Discusses the synthesis, metabolism, and role of lipid mediators in dementia
The human brain is made up of billions of neurons that communicate with each other through chemical messengers, which are referred to as neuroactive substances. These neuroactive substances include neurotransmitters, neuromodulators, and neurohormones. Some neurotransmitters also act as neuromodulators and neurohormones. It is unlikely that there would ever be a consensus about the meanings of these neuroactive substances, including neurotransmitters, since the term ‘neurotransmitter’ has traditionally been used very loosely indeed, to include neurotransmitters, neurohormones, and neuromodulators. Any alterations in the functioning of these neuroactive substances can cause diseases. The brain is the ultimate center that regulates all neurological and behavioral aspects of the body through neuronal communications mediated via various neurochemicals. Thus, neurological and psychiatric disorders are, in most cases, the result of disturbed neurochemical balance. Besides the multifaceted involvement of billions of neuronal cells, the central nervous system is a complex organization with a diverse number of neurotransmitter systems, as compared to the autonomic nervous system, in which the parasympathetic system works on the ‘rest and digest’ phenomenon, and the sympathetic system works on the ‘fight or flight’ phenomenon. There are more than 20 neurotransmitter systems and multiple receptors for each neurotransmitter. Any alterations in neurochemical balance are expressed in the form of neurological or psychiatric disorders such as epilepsy, Parkinson’s disease, Alzheimer’s disease, psychosis, depression, etc. Acetylcholine, noradrenaline, dopamine, and 5-HT are of the utmost importance among neurotransmitters for their profound role in the pathogenesis of various neurological and psychiatric disorders in humans. Yet the involvement of various proteins and peptides, such as neurotrophic factors, growth factors, and endogenous chemical compounds, cannot be ignored. Day by day, the suffering of people due to an imbalance of neurotransmitters is increasing. Various factors, for example stress, diet, genetics, and toxins such as alcohol and nicotine, contribute to this imbalance. This imbalance may lead to mental health complaints. The main purpose of this book is to give a comprehensive overview of the neurological diseases associated with neurochemical imbalances. This book will help readers gain a comprehensive understanding of neuronal signaling and related neurological disorders, as well as status and future opportunities and challenges. It will provide a brief account of neurotransmission, as either a study or high-yield revision aid.
