Book Description
"Neuropsychiatric disorders and suicidal behaviour represent major contributions to mortality in Canada. Among the many factors associated with psychiatric disorders and suicide, alterations in lipids and cholesterol have been demonstrated both peripherally and centrally, supporting their roles as mediating variables in the underlying neuropathology. Cholesterol (CHL) regulation is a complex and dynamic system, and while animal studies also support a mediating role of CHL on brain function, efforts to determine a biological association in humans have achieved only modest gains. While mechanisms governing cholesterol regulation are not entirely understood, cholesterol is well accepted to have important impacts on a variety of brain functions from neurotransmission to synaptic plasticity and neurodegeneration, with unique contributions from neurons, astrocytes, and oligodendrocytes. Given the extensive regulatory feedback mechanisms and the implications in neurological function, determining a biological basis for the association of cholesterol with neuropsychiatric disorders remains an important area of research. This research aimed to explore the neurobiological mechanism whereby alterations in CHL may relate to neuropsychiatric phenotypes. The results presented in chapter 3 suggest, while no clear differences were found in suicide completers with major depressive disorder, expression of several CHL related genes associate more strongly with white matter CHL levels compared to grey matter, suggesting a potential contribution of SORT1, LPL, and ABCA2, in the regulation of white matter CHL. The results of chapter 4 suggest altered phospholipid levels and expression of lysosomal acid lipase A gene in violent suicides in the prefrontal cortex, which would have important consequences for inhibitory neurotransmission. The results of chapter 4 suggest an increase in 24-hydroxycholesterol in the prefrontal cortex of suicide completers and this could have implications for synapse maintenance and loss in the neuropathology of suicide. In regards to CHL levels, however, little evidence in support of alterations in CNS CHL in neuropsychiatric disorders and suicidal behaviour was noted." --

Book Description
Lipids are the most abundant organic compounds found in the brain, accounting for up to 50% of its dry weight. The brain lipidome includes several thousands of distinct biochemical structures whose expression may greatly vary according to age, gender, brain region, cell type, as well as subcellular localization. In synaptic membranes, brain lipids specifically interact with neurotransmitter receptors and control their activity. Moreover, brain lipids play a key role in the generation and neurotoxicity of amyloidogenic proteins involved in the pathophysiology of neurological diseases. The aim of this book is to provide for the first time a comprehensive overview of brain lipid structures, and to explain the roles of these lipids in synaptic function, and in neurodegenerative diseases, including Alzheimer's, Creutzfeldt-Jakob's and Parkinson's. To conclude the book, the authors present new ideas that can drive innovative therapeutic strategies based on the knowledge of the role of lipids in brain disorders. - Written to provide a "hands-on" approach for readers - Biochemical structures explained with molecular models, and molecular mechanisms explained with simple drawings - Step-by-step guide to memorize and draw lipid structures - Each chapter features a content summary, up-to-date references for additional study, and a key experiment with an explanation of the technique

Book Description
Our brain is recognized by all specialists as the most complex entity created in nature. Regarding the extraordinary capacities of its functioning, still incompletely known, the control of the brain by our dietary lipids may seem very improbable to many people. Yet, research has shown that an imbalance in the intake of essential fatty acids is related to conditions as prevalent as depression, bipolar disorder and schizophrenia. Research on psychological disorders including attention deficit hyperactivity disorder, autism, aggressiveness and suicidal behavior are discussed in this text. Several neurodegenerative diseases, such as Alzheimer's, Parkinson's and multiple sclerosis are also explored. Several observations prove that not only are omega-3 fatty acids actively involved in maintaining the noble functions of our brain, but other lipids, including cholesterol, liposoluble vitamins (A, D and E) and some carotenoids play roles as well and are presented in this book. Dietary Lipids for Healthy Brain Function focuses on this important research for human health. This book brings readers, doctors, dietitians and nutritionists arguments that could improve brain development in young people, prevent many nervous diseases and slow down the age-related decline of higher brain functions. This book provides helpful information to improve health in the young as well in the old, using practical and personalized recommendations for preventing and treating nervous pathologies. Features: • Focuses on the importance of dietary lipids on the proper brain functioning. • Provides relevant references demonstrating the efficiency of dietary lipids to maintain a healthy brain. • Introduces lipid sources and describes their roles by lipid groups in behavior issues and various chronic nervous diseases.

Book Description
The understanding of how to reduce risk factors for mental disorders has expanded remarkably as a result of recent scientific advances. This study, mandated by Congress, reviews those advances in the context of current research and provides a targeted definition of prevention and a conceptual framework that emphasizes risk reduction. Highlighting opportunities for and barriers to interventions, the book draws on successful models for the prevention of cardiovascular disease, injuries, and smoking. In addition, it reviews the risk factors associated with Alzheimer's disease, schizophrenia, alcohol abuse and dependence, depressive disorders, and conduct disorders and evaluates current illustrative prevention programs. The models and examination provide a framework for the design, application, and evaluation of interventions intended to prevent mental disorders and the transfer of knowledge about prevention from research to clinical practice. The book presents a focused research agenda, with recommendations on how to develop effective intervention programs, create a cadre of prevention researchers, and improve coordination among federal agencies.

Book Description
Lipids are functionally versatile molecules. They have evolved from relatively simple hydrocarbons that serve as depot storages of metabolites and barriers to the permeation of solutes into complex compounds that perform a variety of signalling functions in higher organisms. This volume is devoted to the polar lipids and their constituents. We have omitted the neutral lipids like fats and oils because their function is generally to act as deposits of metabolizable substrates. The sterols are also outside the scope of the present volume and the reader is referred to volume 28 of this series which is the subject of cholesterol. The polar lipids are comprised of fatty acids attached to either glycerol or sphingosine. The fatty acids themselves constitute an important reservoir of substrates for conversion into families of signalling and modulating molecules including the eicosanoids amongst which are the prostaglandins, thromboxanes and leucotrienes. The way fatty acid metabolism is regulated in the liver and how fatty acids are desaturated are subjects considered in the first part of this volume. This section also deals with the modulation of protein function and inflammation by unsaturated fatty acids and their derivatives. New insights into the role of fatty acid synthesis and eicosenoid function in tumour progression and metastasis are presented.

Book Description
It is becoming increasingly evident that the deficiency of n-3 fatty acids in diet is not only associated with cardiovascular diseases, but also involved in stroke, epilepsy and other neurological and neurodegenerative diseases, such as Alzheimer disease, Parkinson disease, and peroxisomal diseases. In his newest book, Beneficial Effects of Fish Oil on Human Brain, Dr. Akhlaq A. Farooqui expands on the status and therapeutic importance of n-3 fatty acids (major components of fish oil) and their mediators in normal brain and those with neurodegenerative and neuropsychiatric diseases. Farooqui presents the benefits of n-3 fatty acids on Western diet, which is enriched in n-6 fatty acids (major components of vegetable oil) and may promote the above neurological disorders. The book will present readers with cutting edge and comprehensive information on metabolism and roles of neural membrane n-3 fatty acids.

Book Description
Phytochemicals are naturally occurring bioactive compounds found in edible fruits, plants, vegetables, and herbs. Unlike vitamins and minerals, phytochemicals are not needed for the maintenance of cell viability, but they play a vital role in protecting neural cells from inflammation and oxidative stress associated with normal aging and acute and chronic age-related brain diseases. Neuroprotective Effects of Phytochemicals in Neurological Disorders explores the advances in our understanding of the potential neuroprotective benefits that these naturally occurring chemicals contain. Neuroprotective Effects of Phytochemicals in Neurological Disorders explores the role that a number of plant-based chemical compounds play in a wide variety of neurological disorders. Chapters explore the impact of phytochemicals on neurotraumatic disorders, such as stroke and spinal cord injury, alongside neurodegenerative diseases such as Alzheimer's and Parkinson's Disease, as well as neuropsychiatric disorders such as depression and schizophrenia. The chapters and sections of this book provide the reader with a big picture view of this field of research. Neuroprotective Effects of Phytochemicals in Neurological Disorders aims to present readers with a comprehensive and cutting edge look at the effects of phytochemicals on the brain and neurological disorders in a manner useful to researchers, neuroscientists, clinical nutritionists, and physicians.
