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?

The human brain is a complex network of billions of neurons that communicate through electrical impulses. Brain conductivity refers to the efficiency with which these electrical signals travel through brain tissue. It's akin to the speed and clarity of a digital signal through a wire. In layman terms, your brain must function in its peak condition as it is essential for various cognitive processes, including memory, attention, decision-making, and motor control.

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.

If You Spot These 5 Early Signs of Dementia, Head To The Doctor

Updated Nov 4, 2025 | 11:34 AM IST

SummaryDementia, the slow and progressive decline, can be debilitating not only for the person suffering but also for their families. However, early detection can help families live better.
Five early signs of dementa

With a massive population already living with dementia worldwide, the condition has emerged as one of the leading causes of disability and dependence among older adults. According to the World Health Organization (WHO), dementia is the seventh leading cause of death globally and the number of cases is expected to triple by 2050. Despite its rising prevalence, many people remain unaware of its early symptoms, often mistaking them for normal signs of ageing leading to delayed diagnosis and intervention.

What is dementia?

Dementia is an umbrella term for a group of disorders that affect memory, thinking, language and daily functioning. It is not a single disease but a set of symptoms caused by various conditions that damage brain cells. While Alzheimer’s disease is the most common cause, other types include vascular dementia, Lewy body dementia, and frontotemporal dementia (FTD).

There are several risk factors that can increase the likelihood of developing dementia, including age, hypertension, diabetes, obesity, smoking, alcohol consumption and even depression. Though there is no known cure, timely diagnosis and appropriate medical support can significantly improve the quality of life for patients and their families.

Why early detection matters

Experts emphasise that timely intervention is crucial. With proper care, cognitive therapies and medications, doctors can help people living with dementia function more independently and slow down the progression of symptoms. Unfortunately, the early warning signs are often subtle and easy to dismiss as harmless forgetfulness or stress-related behaviour. Recognising them early can make a world of difference.

5 worrying signs you shouldn’t ignore

1. Misplacing items frequently

Occasionally forgetting where you kept your keys or glasses is normal. But if someone repeatedly misplaces items in unusual places—like finding their glasses in the fridge or cleaning supplies in the kitchen cabinet—it may be an early sign of dementia. This behaviour reflects disorientation and short-term memory loss, both hallmark symptoms.

2. Communication difficulties

A person who was once fluent and articulate may begin to struggle with forming sentences, finding the right words, or following conversations. This can be particularly evident in frontotemporal dementia (FTD), which affects the brain’s frontal and temporal lobes—areas responsible for language and behaviour.

3. Memory lapses

Forgetting recent events, appointments, or names of familiar people can be a red flag. While mild forgetfulness can be age-related, persistent memory issues that interfere with daily life should prompt a visit to a doctor.

4. Sudden mood or personality changes

A calm, even-tempered person becoming irritable, anxious, or tearful without any clear reason could be experiencing early emotional changes associated with dementia. Caregivers often notice these subtle shifts before cognitive symptoms become obvious.

5. Confusion about time or place

Getting lost on familiar routes, forgetting where one is, or confusing family members are significant warning signs. Such disorientation can escalate quickly and pose safety risks if ignored.

A growing concern among younger adults

While dementia is most common in people over 65, doctors are observing younger-onset cases, especially with FTD, which can develop in individuals as young as 45. Because the symptoms like personality and behaviour changes, mimic psychiatric conditions such as schizophrenia or aphasia, diagnosis is often delayed.

There’s currently no cure for dementia, but early diagnosis can help manage symptoms effectively, plan care better and support families emotionally and financially. If you notice repeated forgetfulness, communication issues or behavioural changes in a loved one, it’s best to consult a doctor or neurologist at the earliest. Awareness, empathy and timely medical attention can go a long way in helping those affected live with dignity and support.

Gabapentin, A Common Drug For Nerve Pain, Just Got An NHS Warning—Here’s Why

Updated Nov 3, 2025 | 08:36 PM IST

SummaryGabapentin, one of the most commonly prescribed painkillers in the UK, has come under renewed attention after an NHS alert reminded patients about its potential side effects. The prescription-only medicine is primarily used to treat nerve pain caused by conditions such as diabetes, shingles, epilepsy, and restless legs syndrome (RLS).

People taking one of Britain’s most widely prescribed painkillers have been reminded by the NHS to watch for serious side effects that should be reported to a doctor right away.** Gabapentin, available only by prescription, is mainly used to treat nerve-related pain caused by conditions such as diabetes, epilepsy, shingles, and restless legs syndrome.

What Is Restless Legs Syndrome (RLS)?

Restless Legs Syndrome (RLS) is a common condition across the UK. It’s estimated that around 10% of adults experience it, and about 2% deal with uncomfortable symptoms nearly every night. This means roughly 2.2 million people in the UK are likely to live with RLS at some point.

Medicines used to treat RLS include alpha-2-delta ligands, such as pregabalin and gabapentin. The specific drug and dosage vary depending on how severe the symptoms are and whether other health conditions are present. In some cases, long-term treatment may be needed.

What to Know About Gabapentin?

Gabapentin is among the most frequently prescribed medications in Britain. It is available in tablet, capsule, and liquid forms, and can be taken by most adults and by children aged six and older. While the majority of users do not experience side effects, a small number of people report certain reactions.

According to the NHS, “Like all medicines, gabapentin can cause side effects, although not everyone gets them. These common side effects of gabapentin may happen in more than one in 100 people. They’re usually mild and go away by themselves.”

Gabapentin: Common Side Effects

  • Feeling sleepy, tired, or dizzy
  • Nausea or vomiting
  • Diarrhoea
  • Mood changes
  • Swelling in the arms or legs
  • Blurred vision
  • Dry mouth
  • Difficulty getting an erection
  • Weight gain
  • Memory problems
  • Headaches
  • Getting more infections than usual

Some people may experience more serious side effects, such as thoughts of self-harm, swollen glands that do not go away, or persistent stomach pain, which can signal inflammation of the pancreas. The NHS emphasizes that these reactions are rare.

Using gabapentin for an extended period may, in rare instances, lead to dependence, so regular medical supervision is advised while taking this medication.

Who Can and Cannot Take Gabapentin?

The prescribed dose of gabapentin depends on the condition being treated. For adults and older children (aged 12 and above), the usual dosage ranges from 900 mg to 3,600 mg per day, divided into three doses.

For younger children under 12, a doctor will determine the right amount based on the child’s body weight.

Doctors may recommend an alternative to gabapentin in some situations, such as:

  • If the person has had an allergic reaction to gabapentin or similar medicines
  • If they have a history of drug misuse or addiction
  • If they are pregnant or planning to become pregnant
  • If they are following a low-sodium or low-potassium diet, or have kidney problems, since the liquid form of gabapentin contains sodium and potassium

Speaking to a doctor before starting or adjusting gabapentin is essential to ensure the treatment is safe and effective for each individual.

FDA Restricts Fluoride Supplements For Kids After New Health Concerns Emerge

Updated Nov 3, 2025 | 10:00 PM IST

SummaryThe U.S. Food and Drug Administration has announced new restrictions on fluoride supplements for children, saying they should no longer be used in those under age 3 or in older children who are not at high risk of tooth decay. The move follows a federal review ordered by the Make American Healthy Again Commission amid growing concern about potential health effects linked to high fluoride exposure.

The Food and Drug Administration on Friday moved to limit the use of fluoride supplements that are meant to strengthen children’s teeth. This decision marks another step by Health Secretary Robert F. Kennedy Jr. and his team to reassess chemicals long considered standard in dental care.

The FDA announced that these supplements should no longer be given to children under 3 years old or to older children who are not at a high risk of developing cavities. Until now, they had been prescribed for children as young as six months. The move follows a directive from the government’s Make American Healthy Again Commission to review the safety and benefits of these products.

What Are Kids’ Fluoride Supplements?

Fluoride is a mineral known to protect teeth from decay. It can be applied directly to the teeth, added to public water supplies, or taken in supplement form (known as systemic fluoride). It helps strengthen tooth enamel and shields it from the damage caused by plaque. Fluoride also supports the process of remineralization, which repairs the early stages of decay. These supplements are most often given to children.

Now, according to CNN, the FDA has sent notices to four companies warning them of potential enforcement actions for marketing unapproved fluoride-containing ingestible drugs labeled for use in children under age 3, or in older children at low or moderate risk for tooth decay. The agency has also issued letters to healthcare providers, advising them to avoid prescribing these supplements for those groups.

Why Is the Trump Administration Against Fluoride Supplements?

Fluoride has drawn increased attention from the Trump administration following recent research that reopened discussions about the possible health risks of high fluoride exposure. Despite this, most experts continue to highlight the proven safety and dental benefits of fluoride.

The United States began adding fluoride to public water systems in 1945 to make oral care more accessible and affordable. The Centers for Disease Control and Prevention later named water fluoridation one of the top ten public health achievements of the 20th century, alongside vaccines, family planning, and workplace safety improvements.

According to federal data from 2022, most Americans live in areas where fluoride is added to the water. In regions where it is not, doctors often prescribe fluoride tablets or drops to help protect babies and children from cavities. However, this reliance on supplements could grow, as states like Utah and Florida have banned the addition of fluoride to public drinking water, and similar measures are being considered in several others.

In April, the U.S. Department of Health and Human Services and the Environmental Protection Agency announced plans to reevaluate the science around fluoride and issue new guidelines. Health Secretary Robert F. Kennedy Jr. also said he would direct the CDC to stop recommending water fluoridation in local communities.

A new scientific review released Friday concluded that fluoride supplements “should not be used in children under age 3 or by older children who are not at high risk of tooth decay.” The FDA added that “the same property that allows fluoride to kill bacteria on teeth may also affect the gut microbiome, which could have wider health impacts.”

Why Do Dentists Recommend Fluoride Supplements?

Dentists prescribe fluoride tablets, drops, and lozenges to children who live in places without fluoridated water or who are more likely to get cavities. This includes children with poor dental hygiene, those who skip regular dental visits, or those with family members who have dental disease. These supplements are meant to provide the same level of fluoride protection that fluoridated water offers.

According to Dr. F. Perry Wilson, a physician and chronic disease epidemiologist at the Yale School of Medicine, fluoride drops and tablets deliver extra protection against cavities beyond what children get from toothpaste or mouthwash. Since these supplements enter the bloodstream and then the saliva, they help strengthen teeth from within, much like fluoridated water does, as reported by The New York Times.
