Circadian Genes, the Stress Axis, and Alcoholism
Alcohol abuse and dependence are estimated to affect 1 in 8 adults in the United States and several hundred million people worldwide (Grant et al. 2004). To define at-risk populations and develop better treatments, it is important to further identify the genetic and environmental factors that contribute to alcohol addiction. Recent evidence suggests that the body’s internal system that helps...
Alcohol and Puberty: Mechanisms of Delayed Development
Advances in Medications and Tailoring Treatment for Alcohol Use Disorder
Despite decades of research on various methods for treating alcohol use disorder (AUD), AUD remains prevalent throughout the world, making it critical to develop a more comprehensive approach to address the issue. Heavy drinking is the third largest risk factor for global disease burden, leading to enormous social and economic decline (World Health Organization 2014). Each year, alcohol misuse is...
Immune Function Genes, Genetics, and the Neurobiology of Addiction
The nervous system and the immune system interact closely to regulate the body’s immune responses, including inflammatory responses. Accordingly, the term “neuroimmune system” refers to the immune system and those components of the nervous system that help regulate immune responses and also encompasses the hormones and other signaling molecules that convey signals between the immune and nervous...
Childhood Trauma, Posttraumatic Stress Disorder, and Alcohol Dependence
Children exposed to severe adversity early in life are at increased risk of subsequently developing mental health problems, including alcohol dependence. In general, the onset of trauma precedes the onset of alcohol dependence. Although it is impossible to establish a direct causal relationship, this temporal relationship suggests a robust and positive relationship between exposure to early-life...
Introduction
Although the awareness of the negative impact of prenatal alcohol exposure (PAE) was already alluded to in ancient writings1 and the impact of ethanol embryopathy in animal models was studied as early as 1910,2 the conceptualization of a syndrome associated with PAE was not recognized within modern medicine until the mid-20th century.3,4 The syndrome or disorder was not uniformly...
MicroRNAs (miRNAs) are members of a vast, evolutionarily ancient, but poorly understood class of regulatory RNA molecules, termed non–protein-coding RNAs (ncRNAs). This means that in contrast to RNA molecules generated during gene expression (i.e., messenger RNA [mRNA] molecules), they are not used as templates for the synthesis of proteins. ncRNAs are encoded within the genomes of both eukaryotic...
Community Indicators: Assessing the Impact of Alcohol Use on Communities
In the United States and other countries around the world, researchers have long been interested in community-level measurement of population health in the form of community indicators. Community indicators are measures that communicate information about a given dimension of a community’s well-being (Besleme and Mullin 1997). In the United States, the current popularity of community indicators can...
Heavy drinking takes a high toll on society. Other articles in this issue summarize the disease burden and economic cost to society attributable to alcohol use, which provide a powerful incentive to develop and implement ways to reduce them. The focus of this article is on the role of selective (i.e., clinical) prevention and treatment approaches for heavy drinkers and people with alcohol use...
