Alcohol Use Disorder and Schizophrenia or Schizoaffective Disorder

Introduction

Schizophrenia and schizoaffective disorder are heterogeneous psychotic disorders that often cause significant disability, with symptoms that include delusions, hallucinations, disorganization, and cognitive impairment.1 In schizoaffective disorder, the psychotic symptoms are present, along with mood episodes of depression or mania.2 People with these schizophrenia spectrum disorders...

Age, Period, and Cohort Effects in Alcohol Use in the United States in the 20th and 21st Centuries: Implications for the Coming Decades

Introduction

Alcohol consumption, including any alcohol use; patterns of high-risk use, including binge drinking; and alcohol use disorder (AUD) incidence and prevalence, differs substantially over time and by life stage. Variation also occurs across demographic groups, and such differences themselves vary across time and place. In the first quarter of the 21st century, changes in incidence and...

Forebrain-Midbrain Circuits and Peptides Involved in Hyperalgesia After Chronic Alcohol Exposure

Introduction

Chronic pain increases the risk for development of alcohol use disorder (AUD). Given that acute alcohol consumption can reduce pain, humans sometimes drink alcohol for relief of pain. Chronic alcohol consumption, however, can increase pain sensitivity during withdrawal and facilitate pain sensitization related to comorbid pain conditions.1 Ascending and descending nociceptive...

Natural Recovery by the Liver and Other Organs After Chronic Alcohol Use

Introduction

A vast body of evidence from human studies and animal research clearly indicates that chronic, heavy alcohol consumption causes structural damage and/or disrupts normal organ function in virtually every tissue of the body. In heavy consumers of alcohol, the liver is especially susceptible to alcohol-induced injury.1,2 Additionally, several other organs—including the gastrointestinal...

Biobehavioral Interactions Between Stress and Alcohol

In this review, the effects of stress on alcohol drinking are discussed. The interactions between biological stress systems and alcohol drinking are examined, with a focus on the hypothalamic pituitary adrenal axis, corticotropin releasing factor, dynorphin, neuropeptide Y, and norepinephrine systems. Findings from animal models suggest that these biological stress systems may be useful targets...

Co-Occurring Alcohol Use Disorder and Anxiety: Bridging the Psychiatric, Psychological, and Neurobiological Perspectives

“Those who cannot remember the past are condemned to repeat it.”

—George Santayana

Few observations in psychiatry have been documented as long and as consistently as the association between anxiety (and general negative affect) and the chronic misuse of alcohol. Research has shown that up to 50% of individuals receiving treatment for problematic alcohol use also met diagnostic criteria for one...

Alcohol and Cannabis Use and the Developing Brain

Introduction

Adolescence is marked by significant social, emotional, cognitive, and physical changes, as individuals transition from childhood to adulthood. Although the exact definition of adolescence tends to vary, recent findings regarding adolescent development and growth include individuals between the ages of 10 and 24.1 Consistent with this defined age range, the human brain continues to...

AUD Risk, Diagnoses, and Course in a Prospective Study Across Two Generations: Implications for Prevention

Introduction

A large proportion of the population consume alcoholic beverages at some time in their lives. For most people, alcohol consumption is low to moderate and is not associated with harmful physiological, psychological, or social outcomes. However, for a substantial number of individuals, alcohol consumption increases over time; leads to the development of tolerance and alcohol-related...

Translating Alcohol Research Into Practice - Editor's Note

Translational research helps move basic science and clinical laboratory discoveries toward application in health and medicine. Through controlled experiments, basic scientists use animal models to reproduce disease characteristics caused by an agent—in this case, excessively high exposure to alcohol. Through systematic study and observation, clinical research scientists identify symptomatic and...

The Epidemiology of Post-Traumatic Stress Disorder and Alcohol Use Disorder

For more than 40 years, research has shown that individuals with post-traumatic stress disorder (PTSD) use alcohol and experience alcohol use disorder (AUD) to a greater degree than those with no PTSD. AUD and PTSD have shown a durable comorbidity that has extended through decades and through changes in disorder definitions. Some research shows that veterans who have experienced PTSD have a high...
