This digital era is all about catching up with trends, TikToks and reels, but at the cost of what? Many believe all of this happens at the cost of one's health and mental well-being. As a result, the grades of students, especially in high school, when they are exposed to social media the most, start to drop. However, a study based on the University of Birmingham's findings, peer-revied and published by the Lancet's journal for European health policy compared 1,277 students and the rules their 30 different secondary schools had for smartphone use at break and lunchtimes.` The study found something else, contrary to the popular belief.
The study found that banning phones in school is not linked to pupils getting higher grades or having a better mental wellbeing. The study found that a student's sleep, classroom behavior, exercise or how long they spend on their phones did not seem much different for schools with phone bans versus schools without it.
However, the study did find that spending longer time in social media or on smartphones in general may be linked to such measures. This was the first study in the world that looked at school phone rules along with the children's health and education.
In an interview to the BBC, Dr Victoria Goodyear, study's lead author said, that the findings are not against smartphone bans in school, but, a suggestion that bans in isolation are not enough to tackle the negative impacts.
The focus must be on reducing how much time the student spends on their phone, which cannot just be supervised in school.
The schools were chosen from a sample of 1,341 mainstream state schools in England. Among these the behavior of student form schools that banned the smartphones versus those who did not ban it were studied to find out that schools restricting smartphone use did not seem to see the intended improvements on health, wellbeing and focus of the student, as one would have wished to.
The study also used the internationally recognized Warwick-Edinburg Mental Well-Being Scale, a measure of mental well-being focusing entirely on positive aspects. It is a 14-item scale with 5 response categories. This method was used to determine the wellbeing of the children who participated in the research. It further looked at students' anxiety and depression levels.
It also asked from teachers about whether their students were on target, below target or above target in English and maths.
When asked students, they said that the smartphone ban forces you to hang out and chat with your friends and some of them think in lower school, it has helped them spend less time scrolling social media and making lots of friends.
Experts point out that the important part is to help students learn to use their phone in a safe and controlled space. This way, phone-related issues, especially distraction, its impact on your mental health, will be much less. The answer is not ban, but the use of the smartphone in a controlled environment, so students learn to value the "freedom" they have been given to use them at break and lunch.

A recent study has indicated that following a healthy diet consistently may help reduce the risk of dementia, even in those who already show early signs of Alzheimer's disease. The study could help in early management of neurodegenerative diseases like dementia.
According to a new study published in the JAMA Network Open, scientists found that participants who maintained better-quality diets over a period of 15 years were less likely to develop dementia, regardless of whether their blood tests indicated the presence of Alzheimer ’s related biomarkers.
The findings also suggest that healthy eating habits may benefit even after the individual shows signs of the disease processes have begun.
The researchers followed middle-aged and older adults one and a half decades, examining their dietary habits alongside blood biomarkers associated with Alzheimer's disease, including phosphorylated tau217 (p-tau217), glial fibrillary acidic protein (GFAP), and neurofilament light (NfL).
These biomarkers are commonly used to detect early Alzheimer's-related changes and neurodegeneration before symptoms of the disease become visible.
The participants followed a healthy diet, particularly a Mediterranean-style as well as an anti-inflammatory diet. The findings showed that individuals with healthier diets had a lower risk of developing dementia over the follow-up period.
Remarkably, this association was observed even among participants who presented Alzheimer's biomarkers, indicating that diet may offer protective benefits despite early signs.
Alzheimer's disease begins years, and sometimes decades, before memory problems emerge. During this preclinical stage, abnormal proteins accumulate in the brain while individuals remain symptom-free.

The new findings indicate that lifestyle factors such as diet could still influence dementia risk even after these biological changes have started. This reinforces growing evidence that preventive measures need not be limited to people without detectable Alzheimer's pathology.
While the study shows promising results of the effect of a healthy diet on the neurodegenerative disease, it does not prove that diets can directly prevent dementia.
The researchers emphasized that the study was merely an observation, meaning it highlighted an association rather than a direct cause-and-effect relationship. It just supports the idea that long-term healthy eating could have a significant impact on one’s brain health throughout adulthood.
The anti-inflammatory diet, as recommended by Harvard Nutrition Source, helps calm the immune system by choosing foods that reduce inflammation.
This dietary approach encourages a balance of fruits, vegetables, healthy fats, whole grains, and other nutrient-dense foods while avoiding those that trigger inflammation.
On the other hand, Mediterranean diet, long celebrated for its heart-and longevity-promoting benefits, is now gaining attention for its beneficial effects on the brain.
This diet emphasizes plant-based foods, healthy fats such as extra virgin olive oil, nuts, fruits, vegetables, and whole grains, with moderate fish intake.
In another study published in Nature Medicine, researchers observed that individuals at the highest genetic risk for Alzheimer’s disease, particularly carriers of the APOE4 gene variant, showed the most significant reduction in dementia risk when adhering closely to this dietary pattern.

Parkinson’s disease is the second most common neurodegenerative disorder in the world and is the fastest-growing neurological condition worldwide. Its classic hallmarks - resting tremor, bradykinesia, and rigidity usually lead to diagnosis only after extensive dopaminergic neuronal loss has already happened. Newer research, however, highlights a prodromal window that might open decades earlier. There’s an increasing theory that pathological changes of the nervous system could start in a person’s 20s. This means that early detection is not just desirable but could be transformative for clinical outcomes.
Individuals with PD at prodromal and early motor stages alike report symptoms in multiple domains, including behavioral, cognitive, autonomic, sensory, sleep-related, and activities of daily living. Most of these symptoms are subtle and overlap with common conditions, so they aren’t often recognized or are mistaken for ageing, stress or other lifestyle factors. So, identifying consistent patterns amid daily behavioral variations is crucial for improving early PD detection.
Sleep Disturbances: An Early Warning Sign
One of the most robust prodromal markers is REM sleep behavior disorder (RBD). People who are affected have sleep disruption, physically act out their dreams during REM phase (acting out dreams), and vivid dream life and some through sleepwalking — all of them worthy substrates for signals of early brainstem pathology.
Anosmia, a partial or complete loss of the sense of smell, could be PD’s earliest recognizable sign, occurring as much as 10 years before motor signs become apparent. In practice, this means being unable to easily perceive familiar smells like food or coffee. Because this symptom manifests so early and appears so unrelated to the health of the brain, it is rarely taken seriously in clinical practice.
Chronic constipation is a common prodromal symptom indicating reduced gut motility that can predate motor symptoms by years. This observation is consistent with the gut–brain axis hypothesis: gut microbiota dysbiosis disrupts gastrointestinal motility, permeability and inflammation, which may facilitate a prion-like transmission of misformed alpha-synuclein (α-syn) from gut to brain through the enteric nervous system.1 further underscoring the biomarker potential of gastrointestinal symptoms with clinical relevance.
Before tremors are apparent, there can be subtle changes in fine motor control. Trouble with tasks such as handwriting, using electronic devices or manipulating small objects, along with uncharacteristic anxiety or a low mood, can serve as signals of the preclinical stage. Micrographia (progressively smaller and cramped handwriting) is a particularly telling sign from daily life that deserves a neurological workup when it appears without an obvious cause.
Fatigue that never seems to get better with rest affects work performance, social engagement and daily motivation, and can occur long before an official diagnosis. More than half of all PD patients develop at least one form of autonomic dysfunction, which can precede motor symptoms by four years or more, and is now being recognized as a key prognostic biomarker for prodromal PD. Cardiovascular instability, orthostatic hypotension, and urinary irregularities further influence how individuals navigate everyday environments long before a definitive diagnosis is made.
The evidence reviewed here collectively supports a paradigm shift: Parkinson's disease is best defined as systemic, progressive, and with recognizable signals in daily life long before motor signs of decline. Disrupted sleep, anosmia, gastrointestinal changes, fine motor difficulties and chronic fatigue are not complaints in a vacuum; they are potential early signs of a neurological process left unsupervised and now in motion. Incorporating routine clinical assessment of these behavioural precursors and pre-motor signs would allow us to meaningfully extend the opportunity for therapeutic intervention, which could in turn improve patient outcomes across a broad range of CNS disorders.

World Zoonoses Day is being observed today amid growing concerns over the rising threat of zoonotic diseases such as Ebola, Marburg and Nipah. More than 60% of human pathogens are zoonotic, while nearly 75% of emerging infectious diseases originate in animals.
According to the International Society for Infectious Diseases (ISID), spillover events—where pathogens jump from animals to humans—have tripled since the 1980s, fueled by deforestation, wildlife trade, industrial farming and climate change.
In an interview with HealthandMe, Dr Nivedita Gupta, Scientist and Head of the Communicable Diseases Division at the Indian Council of Medical Research (ICMR), outlined the key measures policymakers should prioritize to reduce the risk of future pandemics and strengthen global health security.
Dr Gupta stressed that preventing the next pandemic requires a proactive approach built on integrated surveillance, coordinated data sharing, community participation and stronger indigenous research and development.
According to Dr Gupta, the first priority should be strengthening surveillance across all sectors—across humans, animals and the environment.
"I think first part is that surveillance should be strengthened in all domains, whether it is human surveillance, animal surveillance, wildlife surveillance, as well as environmental surveillance. So, we really need to do integrated surveillance and strengthen all aspects."
She said early detection is critical to identifying emerging pathogens before they become larger public health threats.
"Unless we are able to detect what is happening at various interfaces, we will never come to know that a certain pathogen or a disease is emerging."
The second major priority, she said, is ensuring that surveillance data across sectors is connected.
"If I'm seeing unusual bird or animal deaths, if I'm sitting in human sector, I should also know about it and I should be able to act very timely to understand whether there are any implications on humans and vice versa."
Dr Gupta said data from human, animal and wildlife surveillance systems should "talk to each other" to detect zoonotic diseases at an early stage.
She also highlighted the importance of recognizing reverse zoonosis.
"It's not only that we get infections from animals, birds, and wildlife, but animals also get infected from humans. So, that is known as reverse zoonosis. So, it is both ways."
According to her, anything occurring in the human sector should raise equal alarm in the non-human sectors, and vice versa.
Dr Gupta said community participation is another critical pillar of pandemic preparedness.
"I think we really need massive community sensitization. And community should be our eyes and ears because there are many people who live in remote areas, who live in forest fringes, and they might be seeing many unusual things happening like sudden deaths among animals, carcasses."
She noted that there is currently no system to help people recognize unusual events or report them to the authorities.
"I think those systems wherein our community can be our eyes and ears is something that we really need to develop in our country so that any unusual occurrence which happens within domestic animals or forest fringes or in birds or poultry farms can be immediately reported to the relevant authorities and a timely action can be taken."
Dr Gupta also stressed the need to strengthen the research ecosystem and also work in collaboration with the industry. She said academia and industry currently work in separate silos, making it difficult to rapidly translate research into products.
It is important "to align academia and industry so that industry gets ready-made products which align with the priorities of the country."
The expert added that stronger industry-academia partnerships would help develop products that serve national priorities.
On the role of citizens, Dr Gupta said individuals can contribute by reporting unusual events involving animals or wildlife.
"If I see any unusual thing happening in my domestic settings or around me or if I'm a person residing at forest fringes or in bird sanctuaries, I see unusual deaths, I should be able to report them."
However, she pointed out that governments must first establish a reporting mechanism. "So, currently, even if I want to report today, I don't know where to go."
She said people need to be informed about what constitutes an unusual event and how to report it.
"I think that community sensitization telling them what is unusual, what has to be taken up with a pinch of salt, what has to be reported to the authorities really needs to be told to the people of the country so that they start reporting and they become our sentinels."
