For example, drinking alcohol when you take aspirin can raise your chances of stomach problems or internal bleeding. Mixing it with certain sleeping pills, pain medications, or anxiety drugs can be life-threatening. The study was conducted in over 2,000 individuals including both healthy participants and persons living with HIV. Future studies are needed to investigate both cognitive performance and anatomical structures with cardiovascular factors, lifestyle factors and health as co-variables. In addition, it is not assessed whether cultural differences in cognition are stronger in younger people (Hedden et al., 2002) or in older people (Gutchess et al., 2006). On these grounds, findings of cross-cultural studies are a promising way for gaining insights into universal biological mechanisms as well as the possibilities to influence aspects of cognitive abilities in aging (Park and Gutchess, 2006; Reuter-Lorenz and Park, 2010).

A study by Florida Atlantic University’s Schmidt College of Medicine and collaborators, is one of the first to examine the relationship between self-reported alcohol use and severe head trauma in this group. “This terminology inadvertently suggests there is a ‘non-harmful’ use of alcohol, a notion unsupported by any reliable scientific evidence, including the findings from this study,” Gallina said. Yet the WHO, the EPHA and others have argued that the language waters down alcohol’s health risks, and have called for stronger EU-wide regulation. Late last year, the European Parliament adopted a non-binding resolution on non-communicable diseases such as diabetes and cancer that highlighted the risks tied to the “harmful use of alcohol”. High-risk drinkers were more likely than occasional drinkers to die from cardiovascular disease, in addition to cancer and other causes.

All analyses were conducted using R version 3.3.2 (R Foundation for Statistical Computing, Vienna, Austria) on the National Institutes of Health (NIH) Biowulf Linux cluster. Figures were generated using GraphPhad Prism 7 (GraphPad Software, Inc., La Jolla, CA). Analyses were performed using independent DNA methylation datasets derived from two datasets of blood tissue, two datasets of liver tissue, and one dataset of PFC tissue. The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) was used to diagnose ALC or alcohol abuse in all datasets with the exception of the liver dataset in which alcohol cirrhosis was used as a proxy for ALC. A large-scale study focused on frontal lobe volumes in 1432 individuals, who either refrained from drinking or drank alcohol at light, moderate, or heavy levels but were not deemed with an alcohol disorder (Kubota et al., 2001). Degree of tissue shrinkage was judged on a 4-point scale based on sulcal widening in the frontal lobes.

DNA methylation age is accelerated in alcohol dependence

• That age group will likely include 15–20% with mild cognitive impairment (MCI), which often heralds dementia ().
• By 2040, there will be an estimated 80.8 million people aged 65+, more than double the number in 2000 (35 million).
• According to these models, there are cognitive mechanisms for compensating anatomical changes and reduced function of cognitive networks in the aging bran.
• One potential mechanism involves an increased ability of the liver to break down (i.e., metabolize) and remove alcohol from the body after repeated alcohol exposure (i.e., metabolic tolerance).
• More recent research has found that this distinction does not hold for all cognitive functions in aging, for instance memory, which is highly sensitive to age, even if it has been classified to be one of the crystallized functions (Buckner and Louis, 2004; Salthouse, 2010).

These latest findings echo other research that suggests consuming just one alcoholic beverage per day can shorten a person’s life span by approximately two and a half months. Moderate drinking is described as 20 to 40 grams of alcohol for men and 10 to 20 grams for women a day. The new research, published Monday does alcohol accelerate aging in the journal JAMA Network Open, maintained there was no reduction in heart disease deaths among light or moderate drinkers, regardless of their health or socioeconomic status. These findings contradict the previously held belief that small quantities of alcohol, particularly red wine, are good for the heart.

Researchers have speculated that corticosterone may increase an individual’s alcohol consumption by enhancing alcohol’s rewarding effects (e.g., feelings of euphoria). Similarly, high glucocorticoid levels present in the brain during times of stress may facilitate alcohol’s rewarding properties, providing a potential explanation for survey results indicating that stress may contribute to heavy alcohol use in humans (see Fahlke et al. 1994). This aspect of the stress-alcohol interaction warrants further systematic investigation in humans. The interaction between alcohol and the HPA axis may be bidirectional—that is, not only does alcohol consumption stimulate cortisol secretion, but elevated cortisol levels may increase drinking by magnifying its rewarding effects. Evidence for the latter relationship between alcohol and the HPA axis derives from animal studies in which researchers experimentally manipulated corticosterone levels.

In 1978 using CT, Carlen and colleagues identified shrinkage of the lateral ventricles and cortical sulci in four men who had sustained sobriety from heavy drinking for 4–32 weeks with little further improvement detected later (Carlen, Wortzman, Holgate, Wilkinson, & Rankin, 1978). DNA methylation β-values measured using the Illumina HM450 beadchip microarray were downloaded from the Gene Expression Omnibus from GSE60753. Data consisted of 21 liver samples with alcoholic cirrhosis and 34 normal liver samples.

Changes in Brain Plasticity in the Aging Brain

A different approach for linking AUD and dementia came from a large academic dementia clinic and questioned whether late-onset AUD was related to a specific neurodegenerative disease, which could indicate a pathogenesis for the initiation of alcohol misuse. Late-onset AUD was found to be a more frequent presenting symptom of frontotemporal dementia of the behavioral variant than of Alzheimer-type dementia or semantic variant primary progressive aphasia. The comorbidity of AUD with dementia could confound accurate diagnosis of the primary dementing disorder (de Paula França Resende et al., 2022) and may help explain why some therapeutic attempts at drinking reduction in late-onset AUD do not work (cf., Andersen et al., 2020; Behrendt et al., 2021). The study “shows clear links between consuming alcohol and aging, and points towards a possible link between alcohol and Alzheimer’s,” says Richard Piper, Chief Executive of Alcohol Change UK, who did not participate in the study. “In general, there is an ever-larger body of science showing how, exactly, alcohol causes so much ill-health and so many early deaths.

US dietary guidelines say that “drinking less is better for health than drinking more” and that women should limit themselves to one drink a day and men to two a day. Our studies indicate that chronic parental alcohol use causes enduring mitochondrial dysfunction in offspring, resulting in a reduced NAD+/NAHD ratio and altered expression of the NAD+-dependent deacetylases SIRT1 and SIRT3. Here, we used a multiplex preclinical mouse model to compare markers of cellular senescence and age-related outcomes induced by maternal, paternal, and dual-parental alcohol exposures. Using a mouse model, research by Golding and his team revealed that senescence also happens to be one of the early-aging symptoms that offspring can inherit from parents who daily drink alcohol to the legal limit or more.
