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.

Health authorities in Kerala have sounded an alarm following five suspected cases of West Nile fever (WNF) in Ernakulam.

The cases were reported from Elanji, Eroor in Thripunithura, Pallikkara in Kizhakkambalam, Ponekkara in Edappally, and Palluruthy, The Hindu reported.

While the cases are yet to be ascertained, the southern state of India has a prevalence of mosquito-borne diseases during the summer months.

“We haven’t received any confirmation of WNF cases. These are suspected cases and can be confirmed only after tests are carried out," Dr. R. Shahirsha, District Medical Officer (DMO), Ernakulam, was quoted as saying.

Notably, the authorities have sent the samples for testing, and results will be available in 14 days.

"While no cluster has been observed, precautionary measures to prevent mosquito breeding need to be implemented,” Dr Shahirsha said. Keeping canals clean and preventing mosquito breeding inside homes and in surrounding areas are critical steps, the authorities said.

What is West Nile Fever

The disease is spread through mosquito bites, and most who get infected do not have any symptoms. However, one in every five infected people has a fever, headache, body aches, and other flu-like symptoms.

The West Nile virus also infects the nervous system and is capable of causing serious brain or spinal cord inflammation.

According to the WHO, West Nile Virus is a member of the flavivirus genus and belongs to the Japanese encephalitis antigenic complex of the family Flaviviridae.

The mosquitoes become infected when they feed on birds that carry the virus in their blood, and then bite humans and infect them.

It is found in different parts of the world, including North America, Europe, Africa, Central Asia, Australia, and Asia. Cases in 49 states in the US have been reported, and the total number of symptomatic cases in the US is 51,000 since the first cases were detected in the country in 1999.

What Are The Symptoms?

The symptoms include fever, headache, muscle aches, nausea and vomiting, diarrhoea, rash around the chest and back, swollen lymph nodes, sore throats, and pain behind the eyes.

In severe cases, individuals may have an intense headache, high fever, stiff neck, making you unable to move your chin towards your chest, confusion, muscle weakness, loss of control over your muscle movements, seizures, paralysis, and coma.

How Can It Spread?

While the mosquitoes that feed on infected birds are the carriers, there is still a lack of evidence to determine whether it comes directly from the birds. The incubation period for symptoms to show up is two to six days, but it can extend to 14 days, too.

It can be transmitted from a pregnant person to their fetus, through human milk, blood transfusion, and organ transplant. People who are over the age of 60, have cancer, diabetes, or high blood pressure are more prone to the virus.

Why Is It called West Nile Fever?

It gets its name from the West Nile district, where it was first discovered in 1937 in Uganda.

Treatment

There are no treatments or antiviral medications available for it. However, you can treat the mild symptoms at home with over-the-counter medications that you take for a cold or the flu. The best way to prevent is to protect yourself from mosquito bites.

In a landmark deal, India and New Zealand today signed the India- New Zealand Free Trade Agreement (IN- NZ FTA).

The Agreement was signed by Union Minister of Commerce and Industry Piyush Goyal and New Zealand’s Minister for Trade and Investment Todd McClay at Bharat Mandapam, New Delhi.

The FTA will not only strengthen India’s global economic partnerships but also boost strategic opportunities for the medical devices sector, as well as the country's traditional medicine sector.

In a post on social media platform X, Prime Minister Narendra Modi highlighted the agreement’s "role in promoting traditional knowledge systems, including AYUSH, yoga and organic products, positioning them for greater global relevance".

"The FTA broadens its scope to agriculture productivity, organics, services, mobility, Ayush, and pharma access, making the opportunities all-inclusive and future-oriented," added Commerce Secretary Rajesh Agrawal.

What The FTA Brings To India

For the first time, New Zealand has facilitated trade in Ayurveda, yoga, and other traditional medicine services with India. This landmark provision promotes the global recognition of India’s AYUSH systems, supports medical value travel, and encourages collaboration in wellness services, according to an official statement.

It also reinforces India’s position as a global hub for health, wellness, and traditional medicine services. It gives centre stage to India’s AYUSH disciplines (Ayurveda, Yoga & Naturopathy, Unani, Sowa-Rigpa, Siddha, and Homeopathy) alongside Maori Health practices.

What Are The Industry Leaders Saying?

The experts hailed the India–New Zealand FTA, calling it a strategic opportunity for the medical devices sector.

"For the healthcare and MedTech sector, the agreement is particularly consequential. A dedicated annex on pharmaceuticals and medical devices creates expedited regulatory pathways, with New Zealand agreeing to recognize GMP and GCP inspection reports from the US FDA, the EU’s EMA, and the UK’s MHRA—reducing duplicative compliance burdens and accelerating product approvals for Indian manufacturers," said Pavan Choudary, Chairman, Medical Technology Association of India (MTaI), in a statement.

"A separate annex on health services and traditional medicine opens structured avenues for medical value travel, digital health, and evidence-based AYUSH, positioning India not merely as a goods exporter, but as a global wellness and healthcare services hub," he added.

Rajiv Nath, Forum Coordinator, Association of Indian Medical Devices Industry (AiMeD), also welcomed the India-New Zealand FTA and said that the reduced tariffs and streamlined regulatory cooperation will boost exports.

It will also "enable technology partnerships, and support affordable access to quality devices. The pact enhances competitiveness for Indian manufacturers while ensuring resilient supply chains and mutual recognition standards, strengthening India’s position as a global MedTech hub," Nath added.

However, Choudary cited that there is a significant gap. He cited that the FTA’s regulatory recognition framework does not yet include India’s Central Drugs Standard Control Organization (CDSCO).

"As India’s pharmaceutical and MedTech industry grows in scale, quality, and global reach, the CDSCO is rapidly maturing into a credible, reference-class regulator. Its inclusion in such bilateral recognition frameworks is not a diplomatic nicety; it is a commercial and strategic imperative. Future trade agreements, and indeed revisions to this one, must correct this omission," the expert said.

India’s Cancer Trends Are Shifting, But Not In The Best Direction: ICMR Report

Updated Apr 27, 2026 | 06:59 PM IST

SummaryThe cancer burden in India is evolving; some of it is reflected in lifestyle changes that are driven by economic growth. Early detection can help bridge the prevention and treatment gap.

A new analysis by researchers at the Indian Council of Medical Research (ICMR) points to a mixed picture when it comes to cancer trends in India. While cases of breast cancer and oral cancer in men have been steadily rising over the years, cervical cancer has seen a sharp decline—one of the few clear positives in the data.

Cancer pattern in India

The study, published in the Journal of Public Health, looked at patterns across G20 countries over roughly two decades. Researchers used a method that helps separate the effects of ageing from broader social and behavioural changes. In simple terms, it allowed them to see whether cancer risk itself is increasing, or if higher numbers are just a result of people living longer.

For India, the rise in certain cancers is difficult to ignore. Breast cancer cases have been increasing by around 1.8 per cent each year, while oral cancer in men has gone up by about 1.2 per cent annually. These trends stand in contrast to several high-income countries, where rates have either slowed or, in some cases, begun to fall.

Why are breast cancer cases on the rise?

The reason why breast cancer cases are surging in India is not surprising - with the shift in lifestyle choices, it is almost a no-brainer. Rising obesity, sedentary lifestyle, smoking and alcohol use are some of the key contributors. Reproductive patterns, too, have changed - women are planning pregnancies later, breastfeeding for short duration and also experiencing early onset of periods. While these factors may appear insignificant individually, they collectively play a huge role in the long run.

Oral cancer in India

Oral cancer tells a different story—one that is closely tied to India’s long-standing tobacco habits. The use of smokeless tobacco and betel quid continues to be widespread, particularly among men. Alcohol adds to the risk. What makes the situation worse is that many cases are picked up late, often when the disease is already advanced. The data also shows a clear age pattern: men and women have similar rates until about 40, after which the numbers for men rise sharply.

If there is one area where India has made real progress, it is cervical cancer. The study found that incidence has been dropping by over 4 per cent each year, one of the steepest declines among the countries analysed. Experts attribute this to better awareness, improved hygiene, and gradual improvements in reproductive health services over time.

This decline offers a useful lesson. It shows that sustained public health efforts can make a difference. The recent rollout of HPV vaccination for adolescent girls could push these numbers down even further in the coming years.

Cancer diagnosis and treatment pattern in India

The ICMR report also highlights a big concern - in developed countries, cancer risk decreases with the new generation because of improved diagnosis and treatment infrastructure. However, in India, the pattern is not evident enough - risk appears high across age groups, but the diagnosis and treatment bit is not well taken care of. Lack of mortality data in India is a key concern, which makes it hard to assess how the rising numbers translate to heightened death risk. The trend is still strong enough to require immediate intervention.

Can India's rising cancer burden be curbed?

Researchers say the response cannot be one-dimensional. Expanding access to screening, especially for breast cancer, is crucial. Tobacco and alcohol control policies need to be enforced more effectively to tackle oral cancer. At the same time, the gains seen in cervical cancer underline the importance of vaccination and organised screening programmes.
