The Neurobiological Basis of Suicide


Book Description

With recent studies using genetic, epigenetic, and other molecular and neurochemical approaches, a new era has begun in understanding pathophysiology of suicide. Emerging evidence suggests that neurobiological factors are not only critical in providing potential risk factors but also provide a promising approach to develop more effective treatment and prevention strategies. The Neurobiological Basis of Suicide discusses the most recent findings in suicide neurobiology. Psychological, psychosocial, and cultural factors are important in determining the risk factors for suicide; however, they offer weak prediction and can be of little clinical use. Interestingly, cognitive characteristics are different among depressed suicidal and depressed nonsuicidal subjects, and could be involved in the development of suicidal behavior. The characterization of the neurobiological basis of suicide is in delineating the risk factors associated with suicide. The Neurobiological Basis of Suicide focuses on how and why these neurobiological factors are crucial in the pathogenic mechanisms of suicidal behavior and how these findings can be transformed into potential therapeutic applications.




Marijuana and Madness


Book Description

This book provides a comprehensive overview of the psychiatry and neuroscience of Cannabis sativa (marijuana), with particular emphasis on psychotic disorders. It outlines developments in our understanding of the human cannabinoid system, and links this knowledge to clinical and epidemiological facts about the impact of cannabis on mental health. Clinically focused chapters review not only the direct psychomimetic properties of cannabis, but also the impact consumption has on the courses of evolving or established mental illness such as schizophrenia. A number of controversial issues are critically explored, including whether a discrete 'cannabis psychosis' exists, and whether cannabis can actually cause schizophrenia. Effects of cannabis on mood, notably depression, are reviewed, as are its effects on cognition. This book will be of interest to all members of the mental health team, as well as to neuroscientists and those involved in drug and alcohol research.




Endocannabinoid Signaling

With increasing interest towards the manifold activities of eCBs, this book discusses the chemical, biochemical, and molecular biological assays, and activity of distinct elements of the ECS. These include membrane, nuclear receptors, biosynthetic and hydrolytic enzymes, and membrane transporters and oxidative enzymes. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Timely and cutting edge, Endocannabinoid Signaling: Methods and Protocols is a valuable resource and will help chemists, drug designers, biochemists, molecular biologists, cell biologists, pharmacologists, and (electro) physiologists navigate the mare magnum of endocannabinoid research.




Endocannabinoid Regulation of Monoamines in Psychiatric and Neurological Disorders


Book Description

The past decade has seen tremendous growth in the study of cannabinoid receptor signaling in brain. The impact and consequences of cannabinoid modulation of monoaminergic (dopamine, norepinephrine, and serotonin) circuits is becoming more clear. Scientists have shown significant interaction between these two systems in a variety of psychiatric and neurological disorders such as affective disorders, multiple sclerosis, and pain or pain disorders. The overarching goal of Endocannabinoid Regulation of Monoamines in Psychiatric and Neurological Disorders is to provide current information on advances in the field of endocannabinoid signaling and potential therapeutic applications with a particular emphasis on monoaminergic circuits. ​




Handbook of Basal Ganglia Structure and Function


Book Description

The Basal Ganglia comprise a group of forebrain nuclei which are interconnected with the cerebral cortex, thalamus and brainstem. Basal ganglia circuits are involved in various functions, including motor control, cognition, and mnemonic functions, and the importance of these nuclei for normal brain function and behavior is emphasized by the numerous disorders associated with basal ganglia dysfunction - Parkinson's, Tourette's, Huntington's, cerebral palsy, ADHD, OCD, and others. the Handbook provides a comprehensive overview of the structural and functional organization of the basal ganglia, w




Imaging of the Human Brain in Health and Disease


Book Description

Brain imaging technology remains at the forefront of advances in both our understanding of the brain and our ability to diagnose and treat brain disease and disorders. Imaging of the Human Brain in Health and Disease examines the localization of neurotransmitter receptors in the nervous system of normal, healthy humans and compares that with humans who are suffering from various neurologic diseases. Opening chapters introduce the basic science of imaging neurotransmitters, including sigma, acetylcholine, opioid, and dopamine receptors. Imaging the healthy and diseased brain includes brain imaging of anger, pain, autism, the release of dopamine, the impact of cannabinoids, and Alzheimer's disease. This book is a valuable companion to a wide range of scholars, students, and researchers in neuroscience, clinical neurology, and psychiatry, and provides a detailed introduction to the application of advanced imaging to the treatment of brain disorders and disease. - A focused introduction to imaging healthy and diseased brains - Focuses on the primary neurotransmitter release - Includes sigma, acetylcholine, opioid, and dopamine receptors - Presents the imaging of healthy and diseased brains via anger, pain, autism, and Alzheimer's disease




The Health Effects of Cannabis and Cannabinoids


Book Description

Significant changes have taken place in the policy landscape surrounding cannabis legalization, production, and use. During the past 20 years, 25 states and the District of Columbia have legalized cannabis and/or cannabidiol (a component of cannabis) for medical conditions or retail sales at the state level and 4 states have legalized both the medical and recreational use of cannabis. These landmark changes in policy have impacted cannabis use patterns and perceived levels of risk. However, despite this changing landscape, evidence regarding the short- and long-term health effects of cannabis use remains elusive. While a myriad of studies have examined cannabis use in all its various forms, often these research conclusions are not appropriately synthesized, translated for, or communicated to policy makers, health care providers, state health officials, or other stakeholders who have been charged with influencing and enacting policies, procedures, and laws related to cannabis use. Unlike other controlled substances such as alcohol or tobacco, no accepted standards for safe use or appropriate dose are available to help guide individuals as they make choices regarding the issues of if, when, where, and how to use cannabis safely and, in regard to therapeutic uses, effectively. Shifting public sentiment, conflicting and impeded scientific research, and legislative battles have fueled the debate about what, if any, harms or benefits can be attributed to the use of cannabis or its derivatives, and this lack of aggregated knowledge has broad public health implications. The Health Effects of Cannabis and Cannabinoids provides a comprehensive review of scientific evidence related to the health effects and potential therapeutic benefits of cannabis. This report provides a research agendaâ€"outlining gaps in current knowledge and opportunities for providing additional insight into these issuesâ€"that summarizes and prioritizes pressing research needs.

From Bud to Brain: A Psychiatrist's View of Marijuana


Book Description

The trend toward liberalizing medical and recreational marijuana use is increasing the obligation on clinicians to provide useful information to the public. This book summarizes the science all healthcare professionals need to know in order to provide objective and relevant information to a variety of patients, from recreational and medicinal users to those who use regularly, and to adolescents and worried parents. The author brings two and a half decades of studying cannabinoid research, and over forty years' experience in psychiatric and addiction medicine practice, to shed light on the interaction between marijuana and the brain. Topics range from how marijuana produces pleasurable sensations, relaxation and novelty (the 'high'), to emerging medical uses, effects of regular use, addiction, and policy. Principles of motivational interviewing are outlined to help clinicians engage patients in meaningful, non-judgmental conversations about their experiences with marijuana. An invaluable guide for physicians, nurses, psychologists, therapists, and counsellors.
