As per the latest data released by Transforming Access to Student Outcomes in Higher Education (TASO) and the Policy Institute at King's College London, the number of UK students reporting mental health difficulties tripled. The estimate reveals that around 300,000 students could now be experiencing mental health struggles. Of the total, 18% of students reported some kind of mental health issue in 2024.

As per the reports, this estimate is triple what was reported in 2017, where it was at 6%. Experts also say that Covid-19 pandemic is "often considered to have contributed to this, it does not explain the ongoing rise in mental health difficulties." Another reason could also be the "changing definition and increasing openness about mental health" which has led to a rise in numbers. The report notes, "This trend pre-dates the Covid-19 pandemic and the cost-of-living crisis. Although these factors play a part in students' deteriorating mental health, they cannot therefore be the only explanation."

How Did The Report Conclude?

The report drew data collected over the latest Student Academic Experience Survey of 93,212 students. From the survey, it was found that there exist significant disparities between demographic groups, with women being twice as likely to report mental health difficulties, about 22% as compared to men, at 11%.

What Did The Results Reveal?

The results revealed that students who identified as LGBTQ experienced the highest rates of mental health challenges. This has actually lessened the hope that conditions for LGBTQ students are improving, which may not have been a positive case.

Of them, 42% are bisexual and lesbian students, whereas last year it was 35% and 32% respectively. The report also noted that mental health difficulties among lesbian women and gay men rose three times the rate of straight people, and among bisexual and asexual people, it was twice as high. For trans students, the number jumped from 25% in 2023 to 40% in 2024.

Is The LGBTQ+ Prone To Mental Health Crisis?

As per the Child Mind Institute, being LGBTQ+ does not cause mental health problems, but because these kids often face factors like rejection, discrimination and violence, they are at a higher risk of challenges including depression, anxiety, and even attempting suicide.

A UTAH Health study quotes Anna Docherty, PhD, LP, assistant professor of psychiatry at Huntsman Mental Health Institute that, "likely with any identity, feeling different - or worse, unaccepted as you are is a significant risk factor of mental health struggle." The data reveals that LGBTQ+ teens are six times more likely to experience symptoms of depression than non-LGBTQ+ identifying teens. They are also more than twice as likely to feel suicidal and more than four times as likely to attempt suicide. In the US alone, 48% of transgender adults report that they have considered suicide in the last year, compared to 4% of the overall population.

What Do These Findings Mean?

TASO's academic lead and professor of public policy at King's College London, Michael Sanders said, "LGBTQ students and women bear the brunt of the rise in declining mental health and urgent action is needed to understand and address these trends."

A 24-year-old student from West Bengal has reportedly become the first confirmed heatstroke case of the season in India’s national capital.

According to doctors at Dr Ram Manohar Lohia (RML) Hospital, the young man was admitted in critical condition after developing hyperpyrexia — an extremely high body temperature, and altered mental status while travelling by train to the national capital.

"We received our first heatstroke patient at the RML Hospital on the intervening night of May 20-21. The 24-year-old youth from West Bengal was travelling on a train when his health deteriorated,” said Dr Ajay Chauhan, Director Professor of Medicine, at RML, PTI reported.

“He was brought to the hospital in an unconscious state. We took immediate action and tried to cool down his body,” he said, adding that the boy "is admitted to the medicine ward and is still critical".

As per the doctors, the student had no known pre-existing medical condition, and other possible causes of his symptoms were ruled out before heatstroke was diagnosed.

What Is Heatstroke?

Heatstroke is the most severe form of heat-related illness and is considered a medical emergency. It occurs when the body loses its ability to regulate temperature due to prolonged exposure to extreme heat or dehydration. In most cases, body temperature rises above 104°F (40°C), which can damage the brain, heart, kidneys, and muscles.

“The general features of a patient with heat stroke are: first, his or her body temperature will be very high. It will not be around normal levels like 104, 105, or 106—it will be significantly elevated. Second, the person may be delirious, confused, or even in a state of unconsciousness or coma. The breathing will also be labored,” Dr. Naval Vikram, Professor, Department of Medicine, at the AII India Institute of Medical Sciences (AIIMS), told HealthandMe.

During a heatwave, most patients improve quickly with rest, oral fluids, cooling measures, and moving to a shaded or air-conditioned environment.

"However, if heat exposure continues and the body’s cooling mechanisms begin to fail, the condition can progress to heat stroke, which is a medical emergency. In heat stroke, body temperature often rises above 104°F," Dr. Vaibhav Mishra, Senior Director & Head, CTVS, Max Super Speciality Hospital, told HealthandMe.

What may initially appear as confusion, disorientation, or irrelevant talking can rapidly worsen into:

• altered consciousness,
• seizures,
• coma,
• death.

While it may be impossible to avoid rising temperatures, the focus should be on how much you can protect yourself. Experts suggest the following measures:

• Avoiding exposure to extreme heat as much as possible.
• In case of being exposed, make sure to cover yourself—cover your head and upper body, use an umbrella, stay hydrated, and take breaks in between.
• If you have to work in a hot environment for a couple of hours, take a break in a cooler or temperature-controlled environment for at least half an hour before resuming, rather than continuously working in the heat. These steps can help prevent heat-related problems.
• If symptoms do occur, and it is heat exhaustion, take rest and avoid further activity for some time.
• In more severe cases—if someone shows symptoms like loss of consciousness or very high body temperature—they should be taken to a hospital immediately. Do not try to manage such cases at home.

What Does the IMD Say?

The India Meteorological Department (IMD) has warned of severe temperatures across several states.

"Heat wave to severe heat wave conditions likely to continue to prevail over northwest & central India during the week and over East India during the next 5 days," the IMD said, in its latest update on May 20.

It added that severe heat conditions will persist for at least the next 72 hours across Delhi-NCR, Rajasthan, Uttar Pradesh, Punjab, and Haryana. Temperatures in several cities are expected to touch 47°C to 48°C, with Banda currently emerging as the hottest place in the country.

Alzheimer's disease is a progressive neurodegenerative disorder that affects millions of people worldwide, and it has a long preclinical stage. It is mostly diagnosed at an advanced age, but according to doctors, it begins years before the symptoms become evident. New research shows that blood biomarkers, along with self-reported memory concerns, could give an explanation as to how Alzheimer's disease worsens over time. Therefore, the best time to nourish brain health is during your 40s or 50s.

For this study, researchers used data from the Dunedin Study at the University of Otago, which had been following a few participants for over 50 years. Researchers found a protein known as pTau181, which is associated with self-reported problems linked to memory and thinking skills. Participants were 45 years old at the time of assessment. Typically, an Alzheimer's diagnosis happens at or after the age of 65–70.

When it comes to Alzheimer's, the treatments could only slow down disease progression, but they do not fully restore cognitive function, which is usually lost in the advanced stages. Researchers noted that these treatments work best when taken early, which makes it important to identify the early signs of Alzheimer's disease.

Dementia prevention

Researchers noted that different types of dementia can look different at various stages of the disease. However, the course of progression and treatment can vary from patient to patient. In the past, Alzheimer's could only be diagnosed post-mortem or through invasive procedures such as lumbar punctures. However, researchers are now working towards identifying blood biomarkers that could offer minimally invasive ways to identify high-risk patients for Alzheimer's.

Can Alzheimer's be detected early?

Researchers note that Alzheimer's can be detected in the early stages, and this could provide an opportunity for prevention. It may also offer health benefits for ageing and the brain. Some lifestyle changes include supporting people to remain active, continue engaging in social activities, and address factors such as hearing loss or hypertension. Preventive approaches in this case have worked more effectively the sooner they are implemented. Therefore, it is important to study middle-aged populations, as the signs can start appearing long before the disease is finally diagnosed.

Forgetfulness as an early sign

As people get older, they notice that their memory is not as strong as it used to be. Forgetfulness gradually becomes a common issue with advancing age. However, in some cases, these problems indicate a different story altogether. Recent research shows that minor changes in cognition often begin long before diagnosis, and that is the first moment the disease is truly felt.

Screening for biological Alzheimer's markers

When it comes to screening for biological markers, combining them with subjective memory function reports can help distinguish the earliest signs of Alzheimer's from normal ageing. Proteins such as pTau181 are much higher in Alzheimer's patients, but researchers have not yet ascertained when they begin to accumulate. While researchers did not find that pTau181 was linked to MRI scans measuring cognitive test performance at 45, there were two possible explanations for this:

1. pTau181 might increase during the early stages of Alzheimer's, when people start to experience worsening memory, but it does not appear on an MRI.
2. Alternatively, it could be that high pTau181 is not linked to Alzheimer's risk in midlife, but the protein could still be useful for Alzheimer's diagnosis in older adults.

Vitamin C boosts immunity—and we have known that for a long time now. However, this nutrient has a more crucial role to play. According to a new study from researchers at the University of Waterloo, vitamin C supplements could have a role to play in influencing chemical reactions in the digestive system that are associated with cancer development. Researchers used mathematical models to examine how this happens. Over several decades, North American diets have witnessed a steady rise in exposure to nitrites and nitrates. These are compounds found in cured meat, vegetables, and fruits that are grown in polluted soil and water.

How do nitrates and nitrites affect health?

Nitrates and nitrites play a crucial role in heart and neurological health. They also affect the stomach when it undergoes a chemical reaction known as nitrosation. This leads to the formation of certain chemicals that scientists say can increase cancer risk. Researchers said that, since the 90s, researchers have been working to understand the link between cancer and cancer-causing compounds and have only received conflicting results. The vitamin C study, however, can help explain the inconsistencies.

The team of researchers also developed a mathematical model of the stomach, plasma, salivary glands, and small intestine, and simulated how nitrates and nitrites move through your body and change over time. The researchers' model showed that, when vitamin C is present in foods like spinach and leafy greens, along with nitrates, it could work well to reduce cancer risk in the long run.

Do you need vitamin C supplements daily?

The study also found that taking vitamin C supplements regularly after every meal could have a positive impact on health. It could be effective in reducing the formation of nitrosation products that are linked to cancer risk from nitrates and dietary nitrites found in foods like salami and bacon. Researchers stated that this could help support future research. This acts as a roadmap for future clinical research, and it can help identify the key drivers of these potentially harmful chemical reactions, such as meal timing, nitrite exposure, oral microbiome activity, antioxidant intake, and gastric conditions.

The study, titled “Vitamin C as a Nitrosation Inhibitor: A Modelling Study Across Dietary Patterns and Water Quality”, is published in the Journal of Theoretical Biology.

What are the best natural sources of vitamin C?

Fruits and vegetables are the best sources of vitamin C, some of the best sources being:

1. Guava
2. Amla
3. Bell peppers
4. Kiwi
5. Oranges
6. Lemons
7. Grapefruit
8. Berries
9. Papaya
10. Green chillies

If you are looking for ways to maximise your vitamin C intake, ensure that, from the above list, foods that need cooking are only lightly steamed. Since vitamin C is heat-sensitive and water-soluble, prolonged cooking and boiling can destroy the nutrient.
