Binge Drinking’s Effects on the Developing Brain—Animal Models

Adolescence typically is a time of experimentation and emulation of adult behaviors, and many adolescents initiate alcohol and other drug (AOD) use during this developmental period. Brain development continues during adolescence, which could render the adolescent brain particularly vulnerable to alcohol’s effects. Consequently, adolescent alcohol exposure could result in long-lasting changes in...

Effects of Binge Drinking on the Developing Brain

Binge drinking is a pattern of alcohol drinking that raises a person’s blood alcohol concentration to at least .08%, which amounts to consuming five alcoholic drinks for men and four alcoholic drinks for women in about 2 hours. It is the most common form of alcohol misuse in adolescents and young adults. Heavy drinking includes the same criterion as binge drinking, but with higher frequency (i.e...

Binge Drinking - Editor's Note

The National Institute on Alcohol Abuse and Alcoholism defines binge drinking as a pattern of consumption that causes blood alcohol concentration to rise to .08%—the legal limit for adults ages 21 or older operating a motor vehicle—or more. This level typically occurs after a woman consumes four drinks or a man consumes five drinks—in about 2 hours. Research suggests that three out of four...

Binge Drinking’s Effects on the Body

Alcohol misuse is the fifth-leading risk factor for premature death and disability worldwide, and, adjusting for age, alcohol is the leading risk factor for mortality and the overall burden of disease in the 15 to 59 age group. According to the World Health Organization, in 2004, 4.5% of the global burden of disease and injury was attributable to alcohol: 7.4% for men and 1.4% for women.

Early Life Stress as a Predictor of Co-Occurring Alcohol Use Disorder and Post-Traumatic Stress Disorder

During the critical developmental periods of childhood when neural plasticity is high, exposure to early life stress (ELS) or trauma may lead to enduring changes in physiological stress systems and enhanced vulnerability for psychopathological conditions such as post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) in adulthood. Clinical and preclinical studies have sought to...

“Maturing Out” of Binge and Problem Drinking

This article reviews literature aiming to explain the widespread reductions in binge and problem drinking that begin around the transition to young adulthood (i.e., “maturing out”). Whereas most existing literature on maturing out emphasizes contextual effects of transitions into adult roles and responsibilities, this article also reviews recent work demonstrating further effects of young adult...

Gender Differences in Binge Drinking

A large research literature shows that women consistently consume less alcohol than men, and they experience fewer social problems resulting from drinking than men, but these gender differences vary culturally, demographically, and historically.

Functional and Psychiatric Correlates of Comorbid Post-Traumatic Stress Disorder and Alcohol Use Disorder

Post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) are common comorbid conditions that affect large segments of the population. Individuals with comorbid PTSD/AUD face greater clinical and functional stressors than those with diagnoses of either PTSD or AUD alone. The purpose of this article is to review the phenomenology and functional associations of PTSD/AUD and address the...

High-Intensity Drinking

Binge drinking thresholds have long been set at four or more drinks for women and five or more drinks for men over the course of a few hours. However, a significant number of people regularly consume much higher amounts of alcohol: double or even triple the standard binge drinking threshold. Researchers have begun to distinguish between typical binge drinking and this kind of “high-intensity...

Common Biological Mechanisms of Alcohol Use Disorder and Post-Traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD) are highly comorbid. Although recent clinical studies provide some understanding of biological and subsequent behavioral changes that define each of these disorders, the neurobiological basis of interactions between PTSD and AUD has not been well-understood. In this review, we summarize the relevant animal models that parallel...
