  • Alcohol consumption, particularly heavy alcohol use, is linked to many health conditions, including an increased risk of dementia.<\/strong><\/li>\n
  • However, studies have suggested that consuming small amounts of alcohol might actually decrease the risk of developing dementia.<\/strong><\/li>\n
  • Now, a study has found that low alcohol consumption may not have the suggested protective effect.<\/strong><\/li>\n
  • The study, which used both observational and genetic analysis, suggests that any alcohol consumption may increase a person\u2019s risk of dementia, with the risk increasing as alcohol intake increases.<\/strong><\/li>\n<\/ul>\n

    According to the World Health Organization<\/hl-trusted-source>, consuming any alcohol can affect a person\u2019s health in some way. Alcohol consumption is linked to at least seven types of cancer, including cancers of the breast and bowel, as well as<\/hl-trusted-source> high blood pressure, heart disease, and liver disease.<\/p>\n

    A new genetic analysis has found that although the risk of dementia increases with increased alcohol intake, even low alcohol intake can increase a person\u2019s risk of developing the condition.<\/strong><\/p>\n

    The study, published in BMJ Evidence-Based Medicine<\/em>, used both observational and genetic analyses. While the observational analysis found that moderate drinkers had a lower dementia risk than abstainers, the genetic analysis found that any alcohol intake was linked to an increased risk.<\/p>\n

    \n

    \u201cThis is a highly important and influential finding. It challenges decades of observational research suggesting that light-to-moderate alcohol consumption may protect against dementia. By incorporating genetic analyses, which are less susceptible to confounding and reverse causation, the study demonstrates a likely causal relationship between alcohol and increased dementia risk at all levels of intake. This has direct implications for public health messaging and dementia prevention strategies.\u201d<\/p>\n

    \u2014 Dr. Steve Allder, consultant neurologist at Re:Cognition Health, who wasn\u2019t involved in the study<\/p>\n<\/blockquote>\n

    The effects of heavy drinking on the brain are well known. According to the National Institute on Alcohol Abuse and Alcoholism<\/hl-trusted-source>, alcohol affects areas of the brain that control balance, memory, speech, and judgment, resulting in a higher likelihood of injuries and other negative outcomes.<\/p>\n

    Allder explained how alcohol damages the brain:<\/p>\n

    \u201cAlcohol is neurotoxic: it damages neurons, promotes brain atrophy, disrupts neurotransmitter systems, and accelerates vascular injury. Chronic use can impair thiamine metabolism, leading to cognitive deficits, while even lower levels have been linked to adverse brain imaging findings such as reduced gray matter volume.\u201d<\/strong><\/p>\n

    \u201cAlcohol also increases systemic inflammation and oxidative stress, both of which are implicated in neurodegeneration,\u201d he added.<\/p>\n

    Using questionnaires and the Alcohol Use Disorders Identification Test (AUDIT-C) clinical screening tool, they assessed participants\u2019 drinking. They then monitored participants for an average of 4 years, during which time, 14,540 people developed dementia.<\/p>\n

    In the observational analysis, they found U-shaped associations between alcohol use and dementia risk. Non-drinkers and heavy drinkers both had a higher dementia risk than those who drank fewer than seven drinks a week.<\/strong><\/strong><\/p>\n

    However, the genetic analysis gave different results.<\/p>\n

    \u015eebnem \u00dcnl\u00fci\u015fler, genetic engineer and chief longevity officer at the London Regenerative Institute, who was also not involved in the study, explained why:<\/p>\n

    \n

    \u201cStudies looking at alcohol and dementia can sometimes give conflicting messages. Observational research often suggests that light drinking might protect the brain, showing a U-shaped pattern where moderate drinkers seem at lower risk than heavy drinkers or abstainers. But this can be misleading. People who drink lightly often lead healthier lives \u2014 they may exercise more, eat better, have higher education, or enjoy stronger social connections, all of which reduce dementia risk. At the same time, some people stop drinking because of early health problems or subtle cognitive changes, making abstainers appear at higher risk.\u201d<\/p>\n<\/blockquote>\n

    \u201cGenetic studies offer a clearer picture,\u201d she told Medic<\/strong>al News Today<\/em><\/strong>. \u201cBy using inherited genetic markers linked to alcohol use, researchers can estimate lifetime exposure without the bias of lifestyle or health differences.\u201d<\/strong><\/p>\n

    Lead author, Dr. Anya Topiwala, BM BCh, DPhil, Wellcome Trust Career Development Fellow, Honorary Consultant Psychiatrist, Nuffield Department of Population Health, University of Oxford, UK, explained to MNT<\/em> how the genetic risk for alcohol consumption was actually worked out by another group<\/hl-trusted-source>:<\/p>\n

    \u201cIt\u2019s determined using a genome-wide association study (GWAS). They take a huge sample of individuals and ask them how much they drink. They then look across peoples\u2019 genomes, and test [whether] each genetic variant is more or less common in people who drink more or not. For alcoholic drinks per week they found [d]ifferent genetic variants that were more or less common with higher alcohol intake. Each only contributes a small effect, but we used these genetic variants to \u2018proxy\u2019 alcohol intake.\u201d<\/p>\n

    They found that, in those of European ancestry, a higher genetic risk for alcohol consumption was associated with an increased risk of all-cause dementia.<\/strong><\/p>\n

    Is alcohol harmless?<\/strong><\/p>\n

    \u201cThese [genetic] analyses consistently show that any alcohol, even in small amounts, raises dementia risk, with no protective effect at low levels. While light drinking may look harmless in some studies, the safest choice for your brain is to minimise or avoid alcohol entirely.\u201d<\/p>\n

    \u2014 \u015eebnem \u00dcnl\u00fci\u015fler<\/p>\n<\/blockquote>\n

    Contrary to the observational analysis, the genetic analysis found no U-shaped association between alcohol use and dementia. This analysis found that dementia risk increased steadily with greater predicted alcohol consumption, and that there was no protective effect from low alcohol intake.<\/strong><\/p>\n
