Males and females exhibit discrete attitudes and skills, experience dissimilar emotional and psychological needs, and react differently to peer pressure, lack of self-realization, or other personal and social expectations. In addition, they are differently influenced by family history, and diverge in the perception of self-image and health risks. To complicate the matter on gender dichotomy, male testosterone levels markedly vary over the course of the day, while female levels of sex hormones significantly fluctuate depending upon the menstrual cycle, the pre- or post-menopausal age, and the use of oral contraceptives. All of these factors interact with genetic background and sex hormonal fluctuations, and determine the differences observed in their predisposition to develop an addiction. This term is traditionally associated to the abuse of legal and illegal substances. However, a compulsion toward the engagement in a non-drug-related rewarding behavior, usually involving a natural reward, also activates the brain reward system and engenders persistent behavior, thus resulting in a diminished control over it. These latter behaviors are defined as “behavioral addictions”. This definition encompasses any behavior characterized by the followings: i) feeling of tension or arousal before the action; ii) gratification and/or relief at the time of performing the act; iii) inability to resist an urge or drive even against great obstacles or dangers; iv) absence of consideration for the negative consequences that may affect family, friends, and/or work. As such, behavioral addictions include compulsive food intake and sexual activity, pathological gambling and Internet addiction, excessive exercising, compulsive buying and pyromania. These behaviors, which are often classified as "impulse control disorders", result in actions that are harmful to oneself and/or others, share common features (e.g. compulsiveness, impulsivity, impaired decision-making, craving, tolerance, withdrawal, high rates of relapse), and involve dysfunction of several brain circuits. Derangement from functional neurobiological mechanisms underpinning both sensitivity to reward and inhibitory control can also lead to compulsive behaviors. For instance, pathological gambling and other impulse control disorders (e.g., hypersexuality, compulsive painting, eating and buying) are often reported in Parkinson's disease patients. Gender-dependent differences in the rate of initiation and frequency of misuse of addicting drugs have been widely described. Yet, men and women also differ in their propensity to become addicted to other rewarding stimuli (e.g. sex, food) or activities (e.g. gambling, exercising). The goal of the present Research Topic is to explore and summarize current evidence for gender (and sex) differences not only in drug addiction, but also in other forms of addictive behaviors. Thus, it will include studies showing gender-dependent differences in drug addiction, food addiction, compulsive sexual activity, pathological gambling, Internet addiction and physical exercise addiction. Psychiatric comorbidity, potential risk factors and the underlying neural mechanisms will be also examined, with particular emphasis to the role of sex hormones in modulating addictive and compulsive behaviors.

The science of cannabinoids is 50 years old. These past years provided a remarkable and constant number of breakthroughs, showing that the signaling mediated by endocannabinoids and lipid mediators impacts almost every function of the body. Indeed, this represents a special field of research, which allows tackling the complexity of biological functions, and provides potential therapeutic frameworks for a plethora of diseases. The number of exciting discoveries brought up to the scientific community almost on a daily basis highlights the importance of an updated volume on this topic. Particularly, given that potential therapeutic benefits of cannabis and cannabinoids are currently under heavy analysis in many Countries worldwide. Hence, the main objective of this book is to explore not only some of the many functions of endocannabinoids (and lipid mediators) in physiological control of networks at a cellular and molecular level, but also to extend this knowledge for potential use of cannabinoids and/or drugs regulating endocannabinoid levels in vivo as therapeutic target(s) in neurological and neuropsychiatric disorders. In this book new findings and ideas about the endocannabinoid system and its roles as neuronal circuit modulator related to human brain pathologies characterized by alterations in neuroplasticity will be highlighted. Endocannabinoid roles in key systems controlling appetite, pain, learning and memory, as well as sleep and stress responses will be presented. In addition, pathological processes associated with changes in endocannabinoid signaling will be discussed in the context of anxiety, autism, depression and addiction. This book will provide an excellent background to researchers looking for extending their areas of interest, and to newcomers in the field.

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.

Research in the area of impulse control disorders has expanded exponentially. The Oxford Handbook of Impulse Control Disorders provides researchers and clinicians with a clear understanding of the developmental, biological, and phenomenological features of a range of impulse control disorders, as well as detailed approaches to their treatment.

This book explains the rationale for changes in the DSM-5(R) related to incorporating behavioral addictions alongside substance use disorders; it also illuminates the significance of including the construct of behavioral addictions in this widely used psychiatric diagnostic manual. The chapters herien describe eight behaviors often considered addictions, including gambling disorder, internet gaming disorder, internet addiction, food addiction, hypersexuality, shopping addiction, exercise addiction, and tanning addiction. Also examined are prevalence rates in epidemiological samples, risk factors, and promising treatment approaches. The result is an easy-to-use resource and guide for clinicians, students, and researchers.

This book is a concise, practical guide to both paraphilia and paraphilic disorders as defined by the DSM-5 guidelines. Written by experts in the field, the chapters cover the different types of paraphilic disorder as well as the cutting-edge, emerging issues such as online sex. Unlike any other book on the market, the text also covers the most successful treatment strategies, include the therapeutic, hormonal, and psychopharmacological approaches. The book also discusses the ethical, legal, and cultural issues that are common complications when dealing with paraphilic disorders. Many chapters feature an introduction, diagnostic criteria, summary of evidence, clinical example, recommendations, conclusion, and references. Practical Guide to Paraphilia and Paraphilic Disorders is a valuable resource for psychiatrists, psychologists, residents, and all medical professionals working with patients who may suffer from paraphilia and/or paraphilic disorders.
