Alcohol’s lasting impact: Study reveals how heavy drinking damages cognition

It’s always best to connect with your doctor before quitting alcohol. A weakened immune system has a harder time protecting you from germs and viruses. Dehydration-related effects, like nausea, headache, and dizziness, might not appear for a few hours, and they can also depend on what you drink, how much you drink, and if you also drink water.

A variety of deaths from psychotic disorders – conditions involving delusions and a diminished sense of reality – also implicated alcohol. From 1999 to 2013, drinking has been responsible for hundreds of thousands of deaths in the United States. Among chronic illnesses, which comprise the largest category, cirrhosis of the liver has killed more than 138,000 Americans during this time.

Alcohol use: Weighing risks and benefits

Drinking floods the brain with the neurotransmitter (brain chemical) gamma-aminobutyric acid (GABA), which contributes to feelings of short-term relaxation. It also inhibits another neurotransmitter, glutamate, which regulates mood. Acetaldehyde contributes to inflammation in the liver, pancreas, intestinal tract, and brain, among other organs.

What we don’t know: The significant limitations of alcohol-related health research

If you are drinking heavily or are worried you may be dependent on alcohol, reach out to a healthcare provider before you start reducing your alcohol consumption to determine the safest way to make changes. Alcohol use can damage the hippocampus, the part of your brain responsible for memory and learning. Some studies have found that even light or moderate drinking can lead to some deterioration of the hippocampus. According to the 2019 National Survey on Drug Use and Health from the Substance Abuse and Mental Health Services Administration, 69.5% of people in the United States reported drinking within the last year.

• It’s all too common that problem drinking disrupts bonds with a spouse, family members, friends, coworkers, or employers.
• When you stop drinking, you might notice a range of physical, emotional, or mental health symptoms that ease as soon as you have a drink.
• Assessing the risks and benefits of alcohol consumption remains an active area of research that may lead to major changes in official guidelines or warning labels.
• After adjusting for confounders using econometric models or propensity score matching (PSM), the marginal costs for each risk factor are estimated 12, 13.
• These data show that when individuals die of severe alcohol poisoning, it is nearly always unexpected.

• People have known for centuries that drinking too much alcohol is bad for you.
• Signs and symptoms of withdrawal generally peak at around 72 hours after last intake.
• There’s been an uptick in non-alcoholic drink options, as more and more companies are creating alternatives.
• The cohort included individuals aged 40–69 years who underwent health examinations in 2002–2004 and had no pre-existing risk factor-related diseases.
• The brain is highly vulnerable to the damaging effects of alcohol, which disrupts communication between brain cells.

But when you ingest too much alcohol for your liver to process in a timely manner, a buildup of toxic marijuana addiction substances begins to take a toll on your liver. Your liver detoxifies and removes alcohol from your blood through a process known as oxidation. When your liver finishes that process, alcohol gets turned into water and carbon dioxide. Dr. Sengupta shares some of the not-so-obvious effects that alcohol has on your body.

Risks of heavy alcohol use

• Your immune system works to keep you as healthy as possible by fighting off foreign invaders, such as viruses, bacteria, and toxins.
• If you’re concerned with your alcohol consumption and attitude toward drinking, talk to a healthcare provider as a first step.
• Pancreatitis can be a short-term (acute) condition that clears up in a few days.
• The liver metabolizes most of the alcohol you consume, breaking it down into acetaldehyde.
• The definitions for a drink in the US are the common serving sizes for beer (12 ounces), wine (5 ounces), or distilled spirits/hard liquor (1.5 ounces).
• The short-term physical effects on cognition and motor function speak for themselves.

In reality, there’s no evidence that drinking beer (or your alcoholic beverages of choice) actually contributes to belly fat. Steatotic liver disease used to go by the name fatty liver disease. With these conditions, you’ll only notice symptoms during alcohol intoxication or withdrawal. Over time, alcohol can cause damage to your central nervous system.

Many are exploring ways to cut back, including the Dry January Challenge or alcohol-free drinks. By contrast, another 2023 study found similar rates of death between nondrinkers and light to moderate drinkers. Heavy drinking can also cause problems well beyond the health of the drinker — it can damage important relationships. It’s all too common that problem drinking disrupts bonds with a spouse, family members, friends, coworkers, or employers. The cost of excessive alcohol use impacts everyone, whether they drink or not. Alcoholics Anonymous is available almost everywhere and provides a place to openly and nonjudgmentally discuss alcohol issues with others who have alcohol use disorder.

• Among deaths from acute alcohol poisoning, nearly all were due to accidental poisoning – more than 16,000.
• The alcohol had damaged neural circuits, causing alcohol-exposed rats to process information less effectively.
• Alcohol is a legal recreational substance for adults and one of the most commonly used drugs in the United States.
• But drinking any amount of alcohol can potentially lead to unwanted health consequences.

Notably, alcohol-related deaths have been steadily on the rise among all of these categories since 1999. Cumulatively, the increase in these alcohol-involved fatalities exceeds the growth of the U.S. population – meaning that such deaths are only becoming more frequent. No matter how severe the problem may seem, evidence-based treatment can help people with AUD recover. When it comes to the brain, alcohol acts as a depressant to the CNS. However, it can have inconsistent effects, exciting users under some conditions and sedating users under other conditions. Excitement, typically at lower doses, may be due to alcohol suppressing the inhibitory parts of the brain.

As a result, they eventually need to drink more to notice the same effects they once did. People who drink heavily over a long period of consequences of alcohol time are also more likely to develop pneumonia or tuberculosis than the general population. The World Health Organization (WHO) links about 8.1 percent of all tuberculosis cases worldwide to alcohol consumption. That’s because drinking during pregnancy doesn’t just affect your health. Excessive drinking may affect your menstrual cycle and potentially increase your risk for infertility.
