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:
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.
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.
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.

15-year-old Tanvi Pariyani’s death at AIIMS Delhi has raised questions about the treatment of a rare and complex congenital heart condition she had been living with since childhood.
Tanvi, from Kota, had been visiting AIIMS since she was two. Her medical records listed ventricular septal defect (VSD) with pulmonary atresia, a combination that can make treatment considerably more complicated than just a 'hole in the heart'.
Tanvi’s family has alleged that corrective surgery was repeatedly postponed. AIIMS, however, said its treating team concluded in 2017 that corrective surgery was not feasible because of the complexity of her cardiac anatomy and advised medical management.
The hospital has now constituted a committee to review her complete clinical records, investigations, treatment, expert opinions and the circumstances surrounding her death. An autopsy is also underway.
A VSD is a hole in the wall separating the heart’s two lower chambers. The right side of the heart pumps oxygen-poor blood towards the lungs through the pulmonary artery.
In pulmonary atresia, the normal route through which blood leaves the right side of the heart and reaches the lungs is blocked or has not developed properly.
This can severely block blood flow to the lungs and reduce the amount of oxygen entering the bloodstream.
When pulmonary atresia occurs along with VSD, doctors have to deal with multiple abnormalities rather than simply closing the hole.

Some children may initially require procedures to ensure adequate blood reaches the lungs. Doctors may use medicines temporarily and later create an alternative pathway for blood flow through a shunt.
In some patients, the pulmonary arteries remain very small and the body develops additional blood vessels supplying the lungs.
These vessels, called major aortopulmonary collateral arteries (MAPCAs), may need to be brought together through a procedure called unifocalisation.
A conduit may then be used to connect the heart to the lungs, while the VSD may also need to be closed.
The anatomy can also change as a child grows. Small pulmonary arteries, abnormal blood vessels and rising pressure in the lungs can make later surgical repair more challenging.
According to AIIMS, Tanvi was admitted on August 24 after her condition deteriorated and was being evaluated for a possible heart-lung transplant.
On September 1, she developed severe cyanosis, and her oxygen saturation fell to around 48%. AIIMS said she subsequently suffered a hypoxic spell followed by cardiac arrest. Despite oxygen support and resuscitation, she could not be revived and was declared dead at 5:06 am.
“The Director, AIIMS, New Delhi has constituted a committee to examine the matter in detail, review the sequence of events and establish the facts,” the institute said.
The committee’s findings and autopsy report will be important in establishing what happened and whether any intervention could have altered the outcome.

A new US CDC study has warned of a threefold rise in identifications of Trichophyton indotineae, a skin fungus that causes ringworm and is resistant to standard treatment.
Between 2022 and 2025, T. indotineae was identified in 29 countries, with resistance to terbinafine, a commonly used antifungal medication. The first US case was reported in 2023.
Most cases are treated with terbinafine, either as a cream or a pill.
“Our results reveal a marked global increase in T. indotineae isolation,” the authors wrote in their paper, published in the CDC’s monthly journal, Emerging Infectious Diseases.
During the study period, 566 users from 54 countries submitted 1,657,334 spectra that led to the identification of fungal agents.
However, the research cannot tell us how many people globally are contracting T. indotineae; it only shows that laboratories are detecting it more often.

Ringworm has nothing to do with worms. The misleading name refers to an infection caused by dermatophytes, fungi that thrive in warmth and moisture.
It can affect people of all ages and is highly contagious. Careful attention and immediate treatment are required to control the infection effectively.
Ringworm, also called tinea corporis, is a skin infection caused by fungal spores invading the dead outer layers of the skin. It typically presents as circular, red, scaly patches accompanied by itching or discomfort.
Symptoms of ringworm depend on where the infection develops:
Ringworm is highly infectious and can be transmitted through:
Preventing ringworm is largely about maintaining good hygiene and avoiding contact with infected people or animals.
Left untreated, ringworm can spread across the body or penetrate further, potentially leading to complications such as secondary bacterial infections.

Bhutan has achieved a major public health milestone that several countries, including India, are still attempting to.
The World Health Organization (WHO) has validated Bhutan’s elimination of dog-transmitted rabies as a public health problem, making it the first country in the WHO South-East Asia Region to achieve this milestone.
Bhutan's achievement comes after it recorded zero human deaths from dog-induced rabies since June 2023. It also demonstrated that it has the systems needed to prevent the disease from returning.
In India, rabies continues to remain a major public health concern. Bhutan’s public health achievement, therefore, offers an important lesson for India and other countries. Eliminating rabies means tackling the disease at its source, rather than relying only on treatment after a dog bite.
Bhutan’s progress towards rabies eradication was built over more than a decade through a One Health approach, bringing together human health, veterinary services, local governments and communities.
The country’s Nationwide Accelerated Dog Population Management and Rabies Control Programme focused on mass dog vaccination, population management, surveillance and community awareness.
“Bhutan has shown that eliminating dog-mediated human rabies is possible when strong national leadership, a mature One Health approach and communities come together around a shared goal,” said Dr Nilesh Buddha, Officer-in-Charge, WHO South-East Asia Region.
Bhutan also became the first country to sterilise its entire dog population that roamed freely on the streets through a nationwide programme.
WHO said Bhutan maintained universal, free access to post-exposure prophylaxis (PEP) across all 20 districts, while continuing mass dog vaccination and integrated human-animal surveillance. Cross-border coordination with Indian states is also being strengthened to protect the achievement.
“Bhutan's success shows that the health of humans, animals and the environment we share is inextricably linked,” WHO Director-General Dr Tedros Adhanom Ghebreyesus said.
He added that the fight against rabies is won by bringing health workers, veterinarians and communities together rather than working in silos.

In terms of rabies eradication, India has made progress, but the burden remains substantial.
WHO estimates that 5,726 people die from rabies in India every year, based on an ICMR-National Institute of Epidemiology study. Around 9.1 million animal bites occur annually, with more than three-quarters caused by dogs.
The Indian government’s National Rabies Control Programme also states that around 96% of rabies mortality and morbidity is associated with dog bites.
India already has systems in place that could help with elimination of rabies. The Animal Birth Control Rules, 2023 provide for sterilisation and vaccination of stray dogs, while the National Rabies Control Programme focuses on ensuring access to PEP for people exposed to animal bites.
Bhutan’s experience shows that rabies elimination cannot depend only on giving vaccines to people after bites occur. Vaccinating dogs, controlling dog populations, strengthening surveillance, ensuring rapid access to PEP and improving community awareness have to work together.
Dr Soneet Yadav, ER Consultant, Ruby Hall Clinic, Pune, told HealthandMe, "Rabies keeps claiming lives mainly because people wait long for post‑exposure treatment and because we do not control Rabies in stray and free‑roaming dogs well. To get rid of rabies, India must use a coordinated "One Health" plan that brings together health workers, city officials, vets and animal‑care groups.”
He added, “The important goal is to make sure many dogs get vaccinated all the time while we also run birth‑control programmes and keep a tighter watch on animal‑bite incidents. In hospitals in rural and underserved areas, anti‑rabies shots and Rabies Immunoglobulin (RIG) should always be available. I think people need to hear that every suspected Rabies exposure means they must go to a doctor fast.”
Once the virus reaches your nervous system, modern medicine will not be able to help you as there is no cure. But rabies is 100 per cent preventable if treated in time.
The moment you realise you have been licked, scratched, or bitten by an animal, especially one that is unvaccinated or unknown, Dr Yadav recommends the following things:
