The COVID-19 pandemic may be over, but our immune systems are still feeling the impact. After years of battling constant viral threats, from COVID-19 to seasonal flu and other infections, our body’s defense system is exhausted. Many people continue to experience lingering inflammation, frequent illnesses, and slower recovery times. This extended state of immune stress has compromised us further to chronic illness, including autoimmune diseases and even neurodegenerative diseases such as Parkinson's. So why is our immune system still in trouble? And how do we give it its power back? Understanding immune exhaustion is the beginning of rebuilding our body's natural immunity.

A weakened immune system makes people more susceptible to disease, mental illnesses, and even sleep disorders. Now, new research indicates that immune system depletion may play an important role in the onset of Parkinson's disease, a degenerative neurologic disorder that compromises movement and cognition.

Role of Inflammation in Parkinson's Disease

Dysfunctional immune response is a leading cause of long-standing inflammation within the body, that has been found to contribute towards a multitude of conditions, including cardiovascular conditions, diabetes, depression, and neurodegenerative diseases such as Alzheimer's.

As people age, their immune system naturally becomes less effective. This deterioration, referred to as immune exhaustion, may be a key contributor to the onset and progression of Parkinson’s disease. Rebecca Wallings, a Parkinson’s Foundation Launch Award grant recipient and senior postdoctoral fellow at the University of Florida, believes that an accumulation of exhausted immune cells could be driving neurodegeneration in Parkinson’s patients.

How a Tired Immune System Might Affect Parkinson's?

Parkinson's disease is most commonly linked with the degeneration and loss of dopaminergic neurons—motor nerve cells that produce dopamine, an essential neurotransmitter for movement. While researchers have long suspected inflammation is involved in this neurodegeneration, the mechanisms are not yet well understood.

Wallings' study is on immune cell exhaustion, a process by which aging immune cells fail to control immune responses effectively. Her research indicates that instead of dampening inflammation in Parkinson's patients, attempts should be made to rejuvenate the immune system to regain its functionality.

Energy Deficiency in Immune Cells

One of the major findings of Wallings' work is the function of mitochondrial impairment in immune cell exhaustion. Mitochondria are commonly called the powerhouses of cells, as they are vital for generating energy. As mitochondria age and become inefficient, immune cells fail to function well, potentially accelerating neurodegeneration in Parkinson's disease.

Wallings has found that mutations in the LRRK2 gene, a recognized genetic risk factor for Parkinson's disease, are linked with defective mitochondrial function and immune cell exhaustion. Her current work includes testing various therapeutic approaches to restore mitochondrial function in immune cells with the potential to enhance the immune system and potentially prevent or treat Parkinson's disease.

Will Rejuvenating the Immune System Help in Treatment?

For decades, the standard practice in treating Parkinson's has been to suppress brain inflammation. Yet Wallings' work indicates that instead of slowing down immune responses, restoring the immune system could be a more successful strategy. By addressing mitochondrial impairment and immune resilience, researchers can potentially reverse or slow down Parkinson's disease.

Wallings is now looking into how to rejuvenate immune cells by fixing mitochondria. She studies immune cells from patients with Parkinson's as well as from healthy subjects and performs experiments on animal models to determine if rejuvenation of the immune system could result in improved disease outcomes.

Lifestyle Factors That May Affect Parkinson's Risk

While there is no cure for Parkinson's disease, some lifestyle adjustments may decrease the chances of developing the illness. Since neurodegenerative diseases are associated with chronic inflammation and immune dysfunction, developing habits that enhance immune function might prove helpful.

Diet: There is evidence to suggest that eating in accordance with the Mediterranean or MIND diets, both high in antioxidants, healthy fats, and anti-inflammatory foods, can encourage brain wellness and reduce Parkinson's risk.

Avoiding Dangerous Substances: Restricting alcohol and nicotine use can maintain a robust immune system and suppress inflammation.

Reducing Stress: Chronic stress weakens immune function, so methods such as meditation, exercise, and sufficient sleep can lead to improved overall well-being.

While GLP-1 drugs have shown their effectiveness in reducing weight and managing diabetes, new research suggests they may also help reduce the risk of cancer, particularly breast cancer.

According to a new study by researchers from the University of Pennsylvania, US, women between the ages of 45 and 80 who took a GLP-1 medication were 30 per cent less likely to develop breast cancer. The analysis was based on data from more than 110,000 women.

"While the study does not definitively confirm an association between GLP-1 medications and reduced breast cancer incidence, it does add to the growing body of evidence suggesting that it's worth investigating these weight-loss drugs as potential cancer prevention tools," the researchers said.

"GLP-1 medications are intriguing from a cancer research perspective because they weren't designed for cancer therapy, but they do affect many different targets and pathways associated with cancer development, so we're eager to study them in this context," said Elizabeth McDonald, Professor of Radiology at the University of Pennsylvania's Perelman School of Medicine.

The findings were presented at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago and were also published in JCO Oncology Practice.

Potential New Tool For Cancer Prevention

Breast cancer is the leading cause of cancer mortality among women worldwide and the most common cancer diagnosed overall, accounting for approximately 2.3 million new cases and 670,000 deaths annually, according to the World Health Organization. Every year, breast cancer accounts for about 30% of all new cancer cases in US women.

Beyond breast cancer screening through mammography or MRI, medical or surgical interventions to reduce breast cancer risk remain limited and can be life-altering.

Prophylactic mastectomy is recommended for some individuals with genetic mutations that significantly increase their lifetime risk of breast cancer. Tamoxifen is also highly effective in reducing breast cancer incidence among high-risk patients, but its uptake remains limited because of known side effects. In contrast, GLP-1 medications are already widely used by millions of Americans.

"Ultimately, we want to find better options to prevent breast cancer," McDonald said. "It's been encouraging to see the survival rates for breast cancer improve over recent decades, and we'd love to see the same gains in prevention."

GLP-1 Shows Promise For Multiple Cancers

Another study by researchers at the Cleveland Clinic suggested that glucagon-like peptide-1 (GLP-1) medications may help slow the spread of several obesity-related cancers, including lung, breast, colorectal and liver cancers.

The researchers found that across six of the seven malignancies studied, GLP-1 receptor agonist exposure was associated with reduced metastatic progression, with significant reductions observed in non-small cell lung cancer, breast cancer, colorectal cancer and hepatocellular carcinoma.

The study included 12,112 patients with obesity-related cancers ranging from stage 1 to stage 3. Half of the participants began taking a GLP-1 medication after their cancer diagnosis, while the remaining participants were treated with DPP-4 inhibitors, commonly known as "gliptins", a different class of diabetes medications.

The comparison showed that patients who took GLP-1 medications had a substantially lower progression to stage 4 disease across four cancer types.

"Our study found that use of GLP-1 drugs, compared to DPP-4 inhibitors and other antidiabetic drugs, was associated with a meaningful reduction in cancer progression across four solid tumor types," said study author Mark David Orland from the Taussig Cancer Institute at Cleveland Clinic.

Breast Cancer Symptoms

Recognizing the signs and symptoms of breast cancer can help ensure a prompt diagnosis. Breast cancer can cause a wide array of symptoms, including:

• Pain in the breast
• A lump or thickening of tissue in the breast or underarm
• An unexplained change in the size or shape of the breast
• Suddenly asymmetrical breasts
• Irritation in the breast skin
• Redness or warmth in the breast skin
• A change in the texture of the breast skin (often featuring a thick, pitted appearance resembling an orange peel).

Summer vacations are ongoing, and at a time when heatwaves are at its worse, it is no wonder that most children and teens would prefer staying indoors. And for those who spend hours on video games, a psychologist has answered FAQs for parents. If you are concerned about the possibility of gaming addiction in your children, a senior psychologist lists symptoms and simple techniques to help parents deal with it better.

Neha Cadabams, Senior Psychologist and Executive Director at Cadabams Hospitals, in an interview with Health and Me, answered FAQs about the consequences of gaming addiction in children.

Parents often struggle to differentiate between normal gaming enthusiasm and problematic gaming behaviour. What are some of the earliest psychological warning signs that gaming may be becoming an unhealthy emotional dependency rather than just a hobby?

The difference usually becomes visible not through the number of hours spent gaming, but through the emotional role gaming begins to play in the child’s life. Gaming starts becoming concerning when it shifts from being recreational to becoming the primary way a child regulates emotions, avoids distress, or experiences self-worth.

Some of the earliest warning signs are emotional withdrawal from offline life, irritability or emotional outbursts when unable to game, noticeable sleep disruption, declining interest in activities they previously enjoyed, and increasing dependence on in-game achievements for confidence or validation. Parents may also notice that the child appears emotionally disengaged outside gaming environments or struggles to tolerate boredom, stress, or disappointment without returning to gaming immediately.

What is important to understand is that many children using gaming as an emotional coping mechanism continue functioning normally in school or daily routines initially, which is why the issue is often recognised late.

You mentioned that gaming often becomes an “escape hatch” for painful emotions. What are some of the deeper emotional or psychological struggles children may be trying to escape from through excessive gaming?

In many cases, excessive gaming is less about the game itself and more about what the virtual environment provides psychologically. For some children, gaming offers predictability, achievement, social acceptance, control, or emotional relief that they may not be experiencing consistently in real life.

The underlying emotional struggles can vary significantly. We commonly see children using gaming to cope with loneliness, social anxiety, bullying, academic pressure, low self-esteem, family conflict, emotional neglect, or feelings of inadequacy. For some adolescents, gaming becomes a space where they feel competent, valued, or emotionally safer than they do offline.

What makes this particularly concerning is that the emotional distress itself often remains hidden because the gaming behaviour becomes the visible focus. Families may attempt to reduce screen time without recognising the deeper emotional need the child is trying to fulfil through gaming.

Many teenagers who are struggling emotionally continue to perform normally in academics and daily life. Why is emotional distress among adolescents becoming harder for families to recognise today?

One of the biggest shifts we are seeing today is that emotional distress in adolescents no longer always appears as an obvious emotional breakdown or visible dysfunction. Many young people have become highly functional externally while internally struggling with anxiety, loneliness, emotional exhaustion, or low self-worth.

Adolescents today are also under constant pressure to remain socially connected, emotionally composed, and academically competitive. As a result, many learn to internalise distress rather than express it openly. Parents often expect mental health concerns to appear dramatically, but in reality, the early signs are usually subtle behavioural shifts such as emotional withdrawal, irritability, sleep changes, reduced communication, loss of interest in offline activities, or increasing emotional dependence on digital spaces.

Gaming can sometimes become one of the places where this hidden emotional life quietly reveals itself.

What are some common misconceptions parents have about gaming addiction and mental health?

One of the most common misconceptions is that gaming addiction is simply a discipline problem or a result of poor parenting. In reality, problematic gaming behaviour is often deeply connected to emotional coping, psychological vulnerability, and unmet emotional needs.

Another misconception is that all heavy gaming automatically indicates addiction. Many children and young adults engage deeply with gaming recreationally without it interfering with their emotional health or daily functioning. The concern begins when gaming starts replacing emotional coping, relationships, sleep, education, or the ability to function comfortably offline.

Parents also often focus only on restricting access to games without understanding why the child feels emotionally drawn toward gaming so strongly in the first place. Without addressing the underlying emotional factors, simply removing the game can sometimes intensify distress rather than resolve it.

With gaming becoming a massive part of youth culture in India, how can parents build healthier digital habits at home without making children feel controlled or misunderstood?

The starting point should not be surveillance or punishment, but emotional understanding and communication. Children are far more likely to engage positively with boundaries when they feel emotionally understood rather than judged.

Parents should focus on creating balance rather than framing gaming itself as the enemy. This includes encouraging offline activities, improving emotional conversations within the family, maintaining healthy sleep routines, and helping children build confidence and connection outside digital environments.

It is also important for parents to observe the emotional patterns around gaming rather than only the duration. How does the child behave when they are not gaming? Are they able to emotionally regulate offline? Are they socially connected outside virtual environments? Are they using gaming occasionally for enjoyment, or consistently to avoid discomfort, stress, or emotional pain?

In a country where diseases have become a daily topic of discussion, hypertension is gradually increasing behind closed doors. Also referred to as “the silent killer”, this ailment is notorious for making its presence known without symptoms, unlike many health conditions. By the time it is discovered, it may have already begun to affect vital organs.

Diabetes: A Comorbidity Giving Rise to This Vicious Cycle

One of the most prevalent comorbidities of hypertension is diabetes; together, the two create a difficult combination of chronic conditions affecting a patient's overall health. Diabetes causes high blood glucose (sugar) levels that, over time, damage blood vessels by reducing their ability to stretch or expand. When combined with the pressure caused by hypertension, these already compromised blood vessels can deteriorate rapidly, resulting in further damage.

The combined effects of diabetes and hypertension significantly increase the risk of heart-related complications, such as enlargement of the heart muscle, a reduced ability of the heart to pump blood effectively, and heart failure. Thus, the two conditions create a vicious cycle and emphasise the need for prompt diagnosis and treatment.

According to Dr Ameet Soni, AVP Medical Affairs, CORONA Remedies, “Hypertension and diabetes mellitus (DM) are two of the most common cardiometabolic disorders, often occurring together, and each exacerbates the impact of the other. When combined, these conditions significantly increase the risk of complications such as cardiovascular, cerebrovascular, and renal damage, particularly when symptoms are not identified early or when treatment adherence is inadequate. Minimising the risk of these complications depends on early identification, proactive risk assessment before diagnosis, and long-term adherence to treatment regimens for controlling blood glucose levels and blood pressure.”

According to Dr Manoj Chawla, Diabetologist, P.D. Hinduja Hospital and MRC, Khar, Mumbai, “These diseases are also termed ‘silent partners’, indicative of both their association and the silent damage they cause to bodily functions. The connection between these diseases in India is quite common owing to several factors, including a sedentary lifestyle, poor nutrition, obesity, excessive stress, and a lack of proper diagnosis. Individuals suffering from diabetes have twice the risk of developing hypertension compared with healthy individuals. Since both diseases are asymptomatic in many cases, patients may only discover them when complications arise. Early diagnosis of hypertension and diabetes is therefore vital. Tests such as blood pressure and blood glucose monitoring, weight management, proper nutrition, exercise, adequate sleep, and stress management all help to prevent these risks.”

Here are five alarming signs that your hypertension might be linked to diabetes.

1. Frequent Urination and Thirst: One of the earliest signs that hypertension may be associated with diabetes is frequent urination, accompanied by an abnormal increase in thirst. When blood sugar levels are high, the kidneys work overtime to filter and absorb excess sugar, leading to increased urine production. This, in turn, causes dehydration, prompting an increased thirst response.
2. Fatigue and Weakness: If you are experiencing unexplained fatigue or weakness, this could be a sign that your hypertension is coupled with diabetes. High blood sugar levels prevent glucose from entering the cells efficiently, leaving the body depleted of energy. Hypertension, in turn, places additional strain on the heart and circulatory system, leading to a further decline in overall energy levels.
3. Blurred Vision: The eyes are particularly vulnerable to the effects of both high blood pressure and diabetes. High blood sugar levels can damage the blood vessels in the retina, leading to diabetic retinopathy, which can cause blurred vision. Additionally, hypertension can further exacerbate this damage by increasing pressure within the blood vessels, resulting in worsening vision problems.
4. Numbness or Tingling in the Extremities: Diabetic neuropathy, a common complication of diabetes, causes nerve damage, particularly in the hands, feet, and legs. This nerve damage can lead to symptoms such as numbness, tingling or even a burning sensation in the extremities. When hypertension is present alongside diabetes, the blood vessels supplying the nerves may become compromised, exacerbating the symptoms of neuropathy.
5. Elevated Blood Sugar with Uncontrolled Hypertension: If your blood pressure is consistently high despite treatment or lifestyle changes, it could indicate an underlying issue, such as uncontrolled diabetes. Insulin resistance, which is common in type 2 diabetes, can worsen hypertension by increasing blood pressure due to factors such as weight gain and metabolic imbalances. When blood sugar levels are poorly managed, they can interfere with blood pressure regulation.

Early detection and intervention are key to managing both conditions and reducing the risk of complications. If you are experiencing any of the symptoms mentioned above or have a family history of either condition, it is vital to consult your healthcare provider. Regular screenings, lifestyle modifications and adherence to prescribed treatments can help control both hypertension and diabetes, improving your quality of life and preventing long-term complications.
