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.

Vitruvias Therapeutics’ thyroid medication, recalled nationwide in August, has been elevated to the highest risk level by the US FDA.

The recall was issued because the medication may be superpotent, potentially causing hyperthyroidism (overactive thyroid).

On Wednesday, the FDA updated the recall to Class I, its most serious recall classification. It applies when there is a “reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.”

The affected product is:

• Vitruvias Thyroid Tablets USP 30 mg
• Lot number: 504950
• Expiration date: September 30, 2026

In its August 24 recall notice, the company said the tablets were potentially superpotent.

Risks of Superpotent Thyroid Medicines

Millions of people with hypothyroidism rely on thyroid tablets every day to replace hormones their bodies cannot produce.

However, taking superpotent thyroid tablets can cause hyperthyroidism (overactive thyroid). It can force the body's metabolism into overdrive, speeding up organs and bodily functions.

Left untreated, this constant strain can cause serious health complications across multiple systems in the body.

In addition, people taking the medication can be at risk of

• weight loss,
• heat intolerance,
• fatigue,
• nervousness,
• muscle weakness,
• hypertension,
• chest pain,
• rapid heart rate,
• heart rhythm disturbances.

The lot was distributed nationwide in the US to Vitruvias Therapeutics’ direct accounts between January 31 and September 30, 2025. Of 3,655 units released, 1,955 were sold.

Who Is At Greater Risk?

The company identified the following groups as being at greater risk from superpotent thyroid tablets:

• Elderly people
• Pregnant women
• Infants

Excess thyroid hormones in older adults have been associated with adverse outcomes, particularly those affecting the heart.

Vitruvias Therapeutics said it has not received any reports of adverse events known to be linked to the recall.

The company is notifying wholesalers to stop distributing the recalled product and arranging for its destruction.

What Should Patients Do?

Patients taking Thyroid, USP from Lot 504950 should not stop taking it without first contacting their healthcare provider for guidance and/or a replacement prescription.

Hypothyroidism vs Hyperthyroidism

Speaking to HealthandMe, Dr Shruti Kotangale, Consultant Gynaecologist, Obstetrician and Infertility Expert at AIMS Hospital, Dombivli, explained that both conditions are commonly seen in women.

Hypothyroidism occurs when the thyroid is underactive. Symptoms can include tiredness, weight gain, dry skin, hair fall, constipation, feeling cold, a slow heartbeat and low mood or depression.

Hyperthyroidism occurs when the thyroid is overactive. Symptoms may include weight loss, a fast heartbeat, sweating, anxiety, tremors, irritability, frequent bowel movements and difficulty sleeping.

Women should seek medical attention and manage these symptoms without delay.

Common Symptoms Of Thyroid Disorders

Thyroid disorders may cause a range of symptoms, including:

• Fatigue
• Cognitive changes
• Gastrointestinal problems
• Sensitivity to cold
• Skin and hair changes
• Weight changes

How Is Thyroid Disease Diagnosed?

Diagnosis may involve:

• Physical examination: To check for swelling or nodules in the neck.
• Blood tests: These may measure TSH, T4 and T3 levels, along with thyroid antibodies when conditions such as Hashimoto’s disease or Graves’ disease are suspected.
• Ultrasound or thyroid scans may also be used to assess the thyroid’s structure.

American racing champion and NASCAR Hall of Famer Darrell Waltrip has been diagnosed with Frontotemporal Dementia (FTD), his family has announced.

The 79-year-old former NASCAR driver and broadcaster will be stepping further away from public life following the diagnosis.

According to his family, Waltrip has FTD, which is being complicated by possible chronic traumatic encephalopathy (CTE), which they believe may be linked to injuries sustained during his racing career from 1972 to 2000.

“We wanted to share a health update with all of Darrell’s friends and fans who have supported him throughout his racing career. Recently, Darrell has been diagnosed with Frontotemporal Degeneration (FTD) complicated by possible Chronic Traumatic Encephalopathy (CTE) — likely from injuries incurred during his racing career,” the family said in a statement.

The family said Waltrip currently has only “minor noticeable symptoms” and is “happy and otherwise healthy,” spending time with his wife, Stevie, and their two daughters.

Why Can Repeated Head Injuries Raise CTE Concerns?

Chronic traumatic encephalopathy (CTE) is a progressive brain disease believed to be associated with repeated head injuries. It has most commonly been studied in contact-sport athletes and military personnel exposed to repeated head trauma.

Experts are still studying how the number and severity of head injuries contribute to CTE risk. Importantly, not everyone exposed to repeated head injuries develops CTE, and the condition can currently be definitively diagnosed only after death through examination of brain tissue.

A 2026 study led by researchers at Boston University and Harvard Medical School found that roughly one in four former NFL players who died between 2016 and 2021 had CTE.

CTE And Racing

Although CTE has historically received considerable attention in American football and other contact sports, repeated head impacts can occur in motorsports as well.

Waltrip is not alone. NASCAR Hall of Famer Fred Lorenzen was diagnosed with CTE by researchers after he died in 2024.

What Is Frontotemporal Degeneration?

Frontotemporal degeneration, also known as frontotemporal dementia (FTD), refers to a group of brain disorders that primarily affect the frontal and temporal lobes.

These areas are involved in personality, behavior, language, and other functions. Unlike Alzheimer's disease, memory loss may not be the first or most prominent symptom of FTD.

FTD can develop at a younger age than many other forms of dementia, sometimes affecting people in their 40s or 50s.

The condition can cause changes in:

• Personality and behavior
• Judgment and decision-making
• Emotional responses and empathy
• Speech and language
• Movement and coordination

What Are The Symptoms Of FTD?

Symptoms vary depending on which areas of the brain are most affected and generally worsen over time.

Behavioral Symptoms

• Personality and behavior changes
• Loss of empathy
• Poor judgment and impulsivity
• Socially inappropriate behavior
• Apathy or loss of interest
• Repetitive or compulsive behavior

• Difficulty finding words
• Trouble understanding speech or writing
• Difficulty naming objects
• Increasing difficulty speaking

• Tremors or stiffness
• Muscle weakness or spasms
• Poor balance and falls
• Difficulty swallowing
• Changes in speech or movement

Darrell Waltrip's Racing Legacy

Waltrip is one of NASCAR's most accomplished drivers, with 84 Cup Series victories and three Cup Series championships.

He won the Daytona 500 in 1989 and the Southern 500 in 1992. He also won the Coca-Cola 600 five times, making him the winningest driver in the race's history.

Waltrip later became a familiar voice in NASCAR broadcasting, working as a commentator for many years.

The UK NHS is set to review around 4,500 more breast cancer cases dating back to 2015 after a review found delayed diagnoses and 20 cases involving unnecessary breast removal surgery.

Hundreds of patients suffered harm under County Durham and Darlington NHS Foundation Trust in north-east England., according to the review.

The Trust has apologized and is using specialists from other hospitals to determine whether more women underwent unnecessary operations or received poor care.

"The trust will complete the reviews already under way covering care between January 2023 and February 2025. It will then look back one year at a time, starting with patients treated in 2022 and working backwards towards 2015," it said in a statement.

Review Could Cover 4,500 Cases

Board chair Alison Marshall apologized to women and families affected by the failings.

"I would like to offer a sincere apology to all the women and their families who have been affected by the failings in our breast services," she said, according to the BBC.

"I can't imagine the impact that has had."

She said the Trust could "not turn back the clock" but would be "open, honest and transparent" about the failings.

Chief nurse Gill Hunt said concerns were first raised in 2015 following a "service reconfiguration" and the loss of breast surgical trainee posts.

Till September 2, 2026, a total of 539 cases had been reviewed, and is expected to examine around 4,500 cases if it extends back to 2015.

The Trust said each year's findings will be "carefully considered" before it moves to the next earlier year. As per the report, the review could take five years, with women treated in 2015 potentially having their cases reviewed as late as 2031.

The admission came after the BBC reported last year that more than 200 patients were found to have suffered harm at the CDDFT.

"We have heard again today about the profound and lasting impact that failings in our breast services have had on women and their families," said Chief executive Steve Russell.

"We remain deeply sorry for the harm and distress caused, and for the times when, as a Trust, we should have listened more carefully, asked more questions and acted sooner," Russell added.

About 640 patients have contacted a special helpline seeking a review of their cases. The current review cost about £523,000 in its first year and involved nine reviewers examining around 80 cases a month.

20 Women Had Unnecessary Mastectomies

About 514 cases reviewed by the trust so far, between January 2023 and February 2025, alongside the cases of 640 former patients who contacted a dedicated helpline.

Of the 514 cases, 315 patients have been found to have suffered harm, including 77 who were significantly harmed. One patient is known to have died.

The Trust was found to have a high number of mastectomies compared with other NHS trusts, with operations carried out "too quickly".

Breast Cancer Burden In UK

Breast cancer is the most common cancer in the UK, accounting for roughly 15% of all new cancer cases.

Around 60,763 new cases are diagnosed each year, according to Breast Cancer UK. An estimated 14,000-15,000 mastectomies are performed annually in the UK.

What Is A Mastectomy?

A mastectomy is surgery to remove the whole breast. Depending on the cancer, nearby lymph nodes and surrounding tissue may also be removed. It may be performed on one or both breasts depending on the type of cancer and individual risk factors.

Some patients may undergo breast reconstruction after a mastectomy to restore breast shape and symmetry.
