A new study published in The Lancet Digital Health suggests that biological age of different organs could predict a person's risk of diseases such as cancer, dementia, and heart disease than their actual chronological age. The research analyzed long-term data from Whitehall II study, which had been followed by over 10,000 British adults for more than 35 years.

The blood plasma samples were collected between 1997 and 1999 from participants between ages 45 to 69. Researchers have now examined a follow up data from 6,235 participants, who were by then aged 65 to 89. This was done to see how aging of specific organ may correlate with the development of diseases over two decades.

What Organs Were Studied?

The study measured the biological age of nine key organs, including:

• Heart
• Blood vessels
• Liver
• Immune system
• Pancreas
• Kidneys
• Lungs
• Intestines
• Brain

The researchers were able to find that different organs aged at different rates in different people. In many of the cases multiple organs showed signs of faster aging within the same individual. What is important to note is that those with accelerated aging in certain organs had a higher risk of developing 30 out of the 40 age-related diseases the study had tracked.

Organ Aging And Disease Risk

Some organ-disease connections were expected—people with rapidly aging lungs were more likely to develop respiratory diseases, and those with aging kidneys had an increased risk of kidney-related conditions. However, the study also found less obvious associations.

For example, individuals with fast-aging kidneys were more prone to diseases in other organs, such as the liver and pancreas. Additionally, multiple fast-aging organs were linked to an increased risk of kidney disease.

One of the most surprising findings was that dementia risk was not best predicted by an aging brain but rather by the immune system’s biological age. This suggests that factors such as chronic inflammation and immune health may play a critical role in neurodegenerative diseases.

What Is Organ Specific Blood Tests?

The study also highlights the important of the potential of developing blood tests that could assess the biological age of specific organs. Unlike previous complex methods that measured the organ health, this new approach could make things simple to detect early signs of disease.

The leader author of the study Mika Kivimaki, who is also a professor at the University College London's Faculty of Brain sciences pointed out that such tests could be helpful when it comes to guiding personalized healthcare. In a news release, Kivimaki said, "They could advise whether a person needs to take better care of a particular organ and potentially provide an early warning signal that they may be at risk of a particular disease."

The study reinforces the idea that aging does not affect all organs equally and that looking beyond chronological age could offer better insights into disease prevention. By understanding which organs are aging more rapidly, medical professionals may be able to recommend targeted interventions for individuals at higher risk of specific conditions. Future advancements in organ-specific blood testing could revolutionize how we detect and manage age-related diseases, potentially leading to more personalized healthcare strategies.

Epilepsy is one of the most common neurological disorders and a leading cause of disability worldwide. Research has suggested that associated conditions, such as stigma, anxiety, and depression, can sometimes be more debilitating than the seizures themselves.

Stigma related to epilepsy can exist at both societal and individual levels, with many patients experiencing feelings of shame, fear, discrimination, and social isolation.

Now, research led by AIIMS New Delhi has suggested that yoga may help reduce epilepsy-related stigma while also improving seizure control. The 2023 study, published in Neurology, found that yoga-based interventions may offer benefits for both mental well-being and disease management.

“Yoga has been clinically proven to reduce the ‘felt stigma’ associated with epilepsy. By alleviating anxiety and improving both mindfulness and overall quality of life, mind-body interventions empower individuals to feel more in control and less socially isolated,” lead author Dr. Manjari Tripathi, Head of the Department of Neurology at AIIMS, told HealthandMe.

What Did the Study Find?

According to Dr. Manjari, the study identified three key benefits of yoga for people living with epilepsy:

• Stigma Reduction: Patients who participated in a six-month yoga and psychoeducation program reported a significant reduction in perceived stigma compared with the control group.

• Improved Seizure Control: The yoga intervention was associated with a higher rate of seizure reduction. "Participants were more than four times as likely to experience a greater than 50% reduction in seizures and were significantly more likely to achieve complete seizure remission," Dr. Manjari told HealthandMe.

• Better Mental Health: Yoga practice was linked to lower anxiety levels, improved emotional regulation, and reduced cognitive impairment.

Dr. Rajesh Sagar, Professor of Psychiatry at AIIMS, told HealthandMe that yoga reduced the burden of epilepsy and improved the overall quality of life in epilepsy patients by reducing the perceived stigma. The overall quality of life was also improved in the yoga group.

How Was the Study Conducted?

Researchers conducted a randomized clinical trial involving 160 adults with epilepsy who were followed for six months. Participants were assigned either a structured yoga program or a sham yoga intervention, while both groups also received epilepsy-related psychoeducation.

The yoga program included loosening exercises , breathing techniques, meditation, and positive affirmations.

While the impact on seizure frequency was reduced compared with the control group, the researchers cautioned that larger studies are needed to conclusively determine the effect of yoga on seizure control.

Yoga For Mental Health

Further, mood disturbances have been common among people with epilepsy and often remain inadequately addressed, particularly in developing countries.

According to the researchers, yoga may offer a scalable and accessible option for helping patients manage these challenges alongside conventional treatment.

Dr. Rajesh further told HealthandMe that yoga has well-established benefits for mental health.

“Yoga is important in mental health care, and it has been found that the three important things, which are pranayama, that is, breathing techniques, asanas, that is, physical posture, and dhyana, that is, meditation, have a positive effect on anxiety and even depression, and also improve sleep".

He added that yoga can help reduce stress, improve mood, lower anxiety levels, and enhance sleep quality.

“There is substantial evidence from around the world showing that yoga can benefit people living with certain mental health disorders,” he said.

Every morning, millions begin their day with a quick breakfast and blood pressure (BP) medication swallowed mechanically. But what happens when BP remains uncontrolled despite medicines? Uncontrolled hypertension is one of the most underestimated health threats. Often called the silent killer, it quietly damages the heart, brain, kidneys, and blood vessels.

The BP reading on the cuff captures only a visible measurement. BP that remains above goal over time despite treatment is concerning. Hypertension affects approximately 1.4 billion adults worldwide. Studies suggest that almost 54% of Indian patients have uncontrolled hypertension even while taking ≥2 medications. Thus, treatment does not necessarily mean control.

Why Does BP Control Matter?

Global organizations recommend stricter BP targets, aiming for readings below 130/80 mmHg or even 120 mmHg if tolerated. Studies show that each 10 mmHg reduction in systolic BP can decrease the risk of major cardiovascular events by 20%, stroke by 27%, heart failure by 28%, and death by 13%.

On the other hand, uncontrolled hypertension increases the risk of heart attacks, strokes, heart failure, end-stage kidney disease, type 2 diabetes, and death.

But What If The Numbers Don’t Change Despite Medication?

In persistently uncontrolled hypertension that other causes cannot explain, a hidden culprit called aldosterone is an under-recognized driver. Normally, aldosterone balances sodium and water to regulate BP.

However, in patients with uncontrolled hypertension, aldosterone production may remain abnormally high, causing sodium and fluid buildup, increasing BP.

Approximately 30% of patients with hypertension may have aldosterone dysregulation, and patients with resistant hypertension, obesity, type 2 diabetes, sleep apnea, and hypokalemia are at greater risk. Nearly 10–20% of patients with hypertension are treatment resistant, increasing their risk. In these patients, aldosterone dysregulation could be an important cause.

It is time to look beyond the cuff, as uncontrolled hypertension is a chronic, progressive, and often silent condition with serious consequences. Improving patient outcomes requires greater urgency, earlier intervention, better treatment optimization, and stronger awareness of underlying drivers such as aldosterone.

It is time to identify and treat the root causes of uncontrolled hypertension, so that patients can regain lasting BP control.

Inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, affects millions of people worldwide. The lifelong condition commonly begins in adolescence or early adulthood and can require repeated hospital treatment, long-term immunosuppressive medication, and, in some cases, surgery.

Despite advances in treatment, many patients cycle through multiple therapies without achieving lasting disease control, impacting their lives and costing healthcare systems millions.

Now, a team of UK researchers from the Universities of Oxford, Newcastle, and Cambridge has identified an important driver of inflammatory bowel disease (IBD).

The findings, published in the New England Journal of Medicine, suggest that inflammatory bowel disease is not a single condition but a group of biologically distinct diseases driven by different underlying mechanisms.

"Understanding what drives the inflammation provides a clear explanation for disease in this group of people and opens the door to new treatments that target the autoantibodies themselves or cells that produce those autoantibodies," said Professor Holm Uhlig, a pediatric gastroenterologist and director of the Centre for Human Genetics, Nuffield Department of Medicine, University of Oxford.

What Did the Study Find?

The researchers analyzed more than 4,900 patients with IBD and discovered that:

• A substantial subset of patients shows autoimmune responses to one of the guardians of the immune system, interleukin-10 (IL-10), which leads to uncontrolled inflammation.
• This damaging immune response is the mechanism for one of the strongest known genetic risk factors for IBD.

Antibodies that block interleukin-10 (IL-10), a cell-to-cell messenger that normally acts as one of the body's key controls on inflammation, effectively remove the immune system's natural "brake" on inflammation, allowing inflammatory responses to continue unchecked.

The researchers found high levels of anti-IL-10 neutralizing autoantibodies in the blood of about 3.5% of IBD patients, including those with Crohn's disease and ulcerative colitis, but not in healthy individuals. This could equate to 15,000–20,000 people with IBD in the UK carrying these autoantibodies.

The Genetic Link

The researchers also found that the presence of these antibodies was strongly linked to carriage of a particular genetic variant known as HLA-DRB1*01:03.

The link between HLA-DRB1*01:03 and a severe form of inflammatory bowel disease was first identified by Oxford researchers 30 years ago.

The new findings show that people carrying this variant are far more likely to develop antibodies that block IL-10, helping explain how the gene contributes to disease.

What Could This Mean for Patients?

The researchers say the findings support the development of a blood test to identify this subgroup of patients, helping clinicians move quickly toward more appropriate treatment.

What Is IBD?

As per the Centers for Disease Control and Prevention (CDC), IBD refers to a group of lifelong diseases that affect your intestines. The main types of IBD are ulcerative colitis and Crohn's disease.

Ulcerative colitis affects the large intestine, while Crohn’s disease can inflame any part of the digestive tract. Both are lifelong conditions of unknown cause that trigger abdominal pain, diarrhea and other complications, with no known cure.

What Are The Symptoms Of IBD That People Usually Ignore?

• Diarrhea or changes in bowel movements
• Stomach pain
• Fatigue
• Nausea
• Weight loss

• Dehydration
• Increased risk of colon and rectal cancers
• Low red blood cell count (anemia)
• Reduced bone density
• Joint pain
• Skin changes
• Eye irritation
• Delayed or impaired growth in some children.
