Many of us believe that we are great drinkers and that alcohol does not affect us as much. People who are able to drink without showing any sign of inebriation are known as social drinkers. In short, they are not addicted to alcohol but will not turn down the opportunity to have a good time! While it may seem like it doesn’t affect you, new studies suggest that it is just an illusion, even if you have high tolerance, alcohol affects your cognitive and motor functions more than you think.

The study reveals the below implications and techniques:

• Researchers used a new MRI technique to precisely measure brain electrical activity.
• By comparing brain scans before and after drinking, scientists identified specific areas affected by alcohol and how much brain activity slowed down.
• Participants were chosen to be regular social drinkers without alcohol addiction, ensuring the study focused on the effects of alcohol alone.
• MRI technology provided reliable data on brain activity changes caused by alcohol consumption.

How does the brain react to alcohol?

Think of it as the foundation for your brain's performance. When brain conductivity is high, information flows smoothly, and that helps your brain in rapid processing and response. On the other hand, low conductivity can hinder cognitive function, leading to slower thinking, impaired memory, and difficulties with coordination.

A study conducted at the Neuroscience Research Australia (NeuRA) and UNSW Science unveiled a startling connection between alcohol consumption and brain conductivity.

What is the connection between alcohol consumption and brain activity?

While many people brush off the effects of alcohol as temporary changes in behaviour, the reality is much more complex. Beyond the obvious impacts on coordination and judgment, alcohol significantly alters brain function. Alcohol dramatically slowed down brain activity, especially in areas responsible for decision-making, planning, and physical coordination. This decline was so significant that it resembled the brain changes seen in normal ageing. This means even one drink could temporarily accelerate the ageing process of your brain.

Alcohol and Brain activity: What does the study Imply?

The implications of this research are far-reaching. It provides compelling evidence that alcohol consumption has a direct and measurable impact on brain function. The discovery that alcohol can significantly reduce brain conductivity opens new avenues for understanding the neurocognitive effects of alcohol abuse and dependence. While you may not feel like alcohol is affecting you and you have a high tolerance, it most definitely changes and affects your decision-making abilities and impulse control.

Furthermore, the MRI technique employed in the study could be a valuable tool for assessing the impact of other substances on the brain and for developing interventions to mitigate alcohol-related brain damage.

Eleven forms of cancer are becoming increasingly common among young people in England. Experts at the Institute of Cancer Research and Imperial College London stressed that cancer among younger people is still rare, and that everyone can reduce their risk by simply switching to a healthier lifestyle. However, why tumours have started to develop in people in their late teens, or in their 20s, 30s and 40s, remains unclear. The study further shows that the reasons behind rising cancer cases are elusive. However, this research does indicate a decade-long pattern of people becoming overweight.

Why does one develop cancer?

A team of scientists worked towards understanding why a person develops cancer. They examined national trends in lifestyle and cancer to identify patterns. Researchers found that cases of the following types of cancer were rising:

1. Liver
2. Kidney
3. Thyroid
4. Bowel
5. Multiple myeloma
6. Womb lining
7. Mouth
8. Ovarian
9. Breast
10. Gallbladder
11. Pancreatic

Researchers found that breast and bowel cancers are common among younger adults, with 11,500 cases in a year, while gallbladder and pancreatic cancers were much rarer. It was also noted that ovarian and bowel cancers were exclusively being reported in young people, whereas the other nine were increasing in adults as well. The study by the Institute of Cancer Research and Imperial College London also analysed behavioural patterns known to raise cancer risk.

Researchers also found patterns related to alcohol intake, smoking levels, red and processed meat consumption, and diets low in fibre. These factors play a role in cancer development, but do not conclusively explain why cancer rates are increasing. Century-old tumour patterns, however, may explain why younger people are getting bowel cancer.

How to check for bowel cancer risk?

The report suggested that the only factors that align with an increased risk of cancer are obesity and being overweight, both of which have been on the rise since the 1990s. Extra fat tissue can alter hormones such as insulin, which can increase cancer risk. For instance, in the case of bowel cancer, for every 100 extra cases, 20 could be attributed to excess weight, while 80 remain unexplained. Researchers also note that it is important to prevent all cancers, not just the additional cases. It is estimated that nearly 40 per cent of cancers worldwide can be prevented through appropriate lifestyle choices, such as quitting smoking.

How to reduce cancer risk?

Quitting smoking and avoiding alcohol are among the simplest and most well-known ways of reducing cancer risk. However, experts say that other measures can also help. Maintaining a healthy body weight and staying physically active are simple ways to reduce cancer risk. Researchers also emphasise that while cancer rates are rising among younger people, the risk of tumours remains significantly higher in older age groups.

Researchers found that one in 1,000 people aged 20, 30 and 40 are diagnosed with cancer every year, compared to one in 100 among older age groups aged 50, 60 and 70. The search for other risk factors continues. Inflammation, sweetened drinks, gut bacteria, and air pollution must be addressed in time to reduce cancer risk. It is also being investigated whether improvements in cancer detection are contributing to earlier diagnoses in younger individuals.

The study’s findings are published in the BMJ Oncology.

Cervical cancer is a slow-developing cancer that occurs in the lower part of the uterus. It is caused by a persistent HPV infection, which usually occurs in women in their prime. Some of the symptoms of cervical cancer include pelvic pain and abnormal bleeding. Experts say that timely detection through a Pap smear or prevention with an HPV vaccine can make a difference. However, according to a study published in The Lancet, high-income countries are on the right track to eliminate cervical cancer.

What causes cervical cancer?

The study published in The Lancet notes that high-income countries are on the right track towards cervical cancer prevention through vaccination and screening. By 2048, low- and middle-income countries will see only slight reductions over the next century. As a result, the gap between regions will likely widen dramatically. Experts have found that 99 per cent of cervical cancer cases are linked to infection with human papillomaviruses (HPV), a virus that is transmitted through sexual contact.

Preventing cervical cancer

Cervical cancer, according to experts, can be prevented through the HPV vaccine and regular screenings. The elimination target set by the World Health Organization is fewer than four cases per one lakh women. Every country, as per the WHO, must meet the ‘90-70-90’ targets by 2030. This means 90 per cent HPV vaccine coverage among girls by the age of 15, 70 per cent of women screened between the ages of 35 and 45, and 90 per cent of women with pre-cancer and cancer treated. This would be considered being on track for cervical cancer elimination in the coming century.

Researchers note that reaching the WHO targets for screening and vaccination, for HPV elimination, or for introducing universal vaccination with high coverage, is essential for the elimination of cervical cancer. This could help bridge global inequalities in disease management. Achieving the 90-70-90 goal can avert 37 million cancer cases by the next century, thereby accelerating progress in eliminating the disease. The model, however, suggests that most countries are unlikely to reach the target without increasing investments in this direction.

The research model

Researchers proposed five HPV-centric prevention strategies. Under a status quo model, cervical cancer incidence could decline by 23 per cent, consequently leading to inequalities in disease management. Experts found that achieving 90 per cent vaccination coverage in low- and middle-income countries would reduce inequalities and help eliminate cancer. Research authors also noted that recent advancements, such as single-dose vaccines at a lower cost, could accelerate cervical cancer elimination worldwide.

Global efforts from international agencies and governments are also important. A September 2022 study published in The Lancet Oncology found that a single-dose cervical cancer vaccine with lasting protection and 90 per cent coverage could prevent 78 per cent of cancer cases in India.

After a long day at work, the occasional glass of wine helps many people unwind. However, some struggle to strike a balance and get involved in binge drinking habits. If you are someone who is unable to give up that frequent dose of cocktails, then a study claims that weight loss drugs can come to your rescue. Experts have found that alcoholics who are obese, when given Wegovy, could curb their drinking habits by as much as 70 per cent. A study in Denmark was led by experts from the Mental Health Centre Copenhagen and Frederiksberg Hospital, and experts used semaglutide on 108 obese patients seeking treatment for alcohol use disorder.

Can weight loss drugs help curb drinking habits?

Half the participants in the study were given 2.4 mg of the drug for six months. The other half were also given a dummy drug. Researchers found that people who were on weight loss drugs had fewer days of binge drinking. Furthermore, their alcohol cravings also dipped compared to people on placebo. Before the trial began, participants engaged in binge drinking on an average of 17 days per month.

Researchers also noted that people who were given semaglutide for six months saw their binge drinking days reduce to five in a 30-day period. This correlated to a 40 per cent dip in drinking days in a month, compared to a 26 per cent dip in the placebo group. These dummy drugs helped reduce drinking days to nine. In terms of alcohol quantity, trial participants drank roughly 2,200 g in the 30 days before the trial started. This meant about 154 drinks in a month, or five per day. Over a period of six months after the trial, there was an impressive 70 per cent dip — from an average of 154 drinks a month to 46 drinks a month in people who were taking semaglutide.

What are the benefits of semaglutide?

Alcohol consumption dipped by an impressive 47 per cent in the dummy drug group as well. The study found that overall alcohol consumption can be reduced among semaglutide users compared to people who were taking the placebo. Researchers found that semaglutide not only affects appetite but also influences biological mechanisms associated with addiction.

Independent researchers found that the results were encouraging and strong enough to be used in helping people struggling with alcohol use problems. However, more research is required in this area. Researchers also noted that there were no follow-ups with the participants after the semaglutide treatment ended. This means that experts could not be fully certain whether people reverted to their old drinking habits once they stopped using the medicine.

What are the health benefits of weight loss drugs?

Apart from inducing weight loss, weight loss drugs have the following health benefits:

1. Quitting smoking
2. Can help kick drug habits such as cocaine use
3. Lower risk of heart attack or stroke
4. May help reduce blood pressure and cholesterol to improve heart health
5. Lower risk of dementia
