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.

Dhurandhar 2 actor Mustafa Ahmed, who played Rizwan in the film, opened up about growing up with dyslexia. He shared that he struggled with reading and writing, but sports and dancing came naturally to him.

"I was not a bright kid. I was dyslexic and came from an Afghan background. But I was always physical, I was good at sports, and I picked up dancing naturally. Anything that involved using my body, I was good at it,” said Mustafa, who trained has Hrithik Roshan, in the Alpha Coach podcast.

What Is Dyslexia?

Dyslexia is a learning difficulty that affects reading, writing, and spelling. However, it has nothing to do with intelligence.

Common signs of dyslexia include:

• Difficulty reading or recognizing words
• Trouble with spelling and writing
• Confusing similar-looking letters (like b/d or p/q)
• Slow reading speed and poor comprehension
• Difficulty following written instructions

This means that children with dyslexia are simply wired differently and may need to focus on other learning areas.

How Did Mustafa Overcome Dyslexia?

Mustafa did exactly that. He focused on training hard and eventually worked with big stars like Hrithik Roshan. That’s when he caught the attention of Aditya Dhar, the maker of Dhurandhar. Aditya saw potential in him and encouraged him to pursue acting, helping launch his journey in the industry.

Growing up, Mustafa, who revealed in an interview, faced challenges in school due to his learning difficulties. Tasks like reading scripts or memorizing lines may not have come easily at first. However, with determination, support, and self-belief, he was able to overcome these barriers.

However, today as a rising star, his story is a reminder that with the right support, early diagnosis, and self-belief, children with dyslexia can truly thrive.

Signs and symptoms of dyslexia

Doctors say signs of dyslexia can look different at each age. It happens because your brain grows and learns in new ways as you get older. You may notice your child has:

• Has difficulty learning or recognizing letters
• Has trouble rhyming words
• Mixes up words that sound similar
• Find it difficult to read simple words after learning letter sounds
• Have trouble remembering letters, even after lots of practice
• Avoiding tasks that have to do with reading
• Feeling sick or anxious before school or homework time
• Struggling in school

Can You Treat Dyslexia?

Doctors say even though dyslexia is a lifelong condition, it can be effectively managed with the help of interventions like:

• Phonics-based reading programs
• One-on-one tutoring
• Speech and language therapy
• Use of assistive technology like audiobooks and text-to-speech tools

With these strategies, individuals with dyslexia can improve their reading skills and excel in their chosen fields.

Mel Schilling, an Australian psychologist and a dating expert died at 54. Her husband Gareth Brisbane announced the death in a social media statement.

What Happened To Mel Schilling?

Schilling was diagnosed with colon cancer in December 2023. Just two weeks ago she said that the disease had spread to her brain. "I honestly don't know how long I have left," she wrote.

According to her husband, she died "peacefully, surrounded by love". “This is a woman who, through two years of chemotherapy, when she could barely lift her head from the pillow, never complained and never stopped showing courage, grace, compassion and empathy, and never missed a day of filming,” Brisbane wrote.

She was also an expert on 'Married at First Sight Australia' for 12 years and because of her illness she stepped down as a dating expert.

How Does Cancer Spread To Other Parts Of The Body?

Schilling said that her cancer had spread to her brain. as per the Cancer Research UK, cancer cells can spread to other parts of the body through bloodstream or lymphatic system. They can then start to grow into new tumors. The National cancer Institute notes that cancer cells spread through the body in a series of steps, which include:

• growing into, or invading, nearby normal tissue
• moving through the walls of nearby lymph nodes or blood vessels
• traveling through the lymphatic system and bloodstream to other parts of the body
• stopping in small blood vessels at a distant location, invading the blood vessel walls, and moving into the surrounding tissue
• growing in this tissue until a tiny tumor forms
• causing new blood vessels to grow, which creates a blood supply that allows the metastatic tumor to continue growing

What Is Colon Cancer?

Colon (colorectal) cancer begins when small growths called polyps form on the inner lining of the colon or rectum. Over time, changes in the DNA of these cells can cause the polyps to become cancerous.

As abnormal cells multiply, they replace healthy cells and eventually form a mass known as a tumor. This process develops slowly, often taking up to ten years for a precancerous polyp to turn into cancer and begin showing symptoms.

Colon cancer poses serious health risks because cancerous cells can invade healthy tissues. Over time, they may break away and spread to other parts of the body, making detection more difficult since the symptoms can resemble other conditions.

How Can You Get Screened For Colon Cancer?

You can get examined by a colonoscopy. A colonoscopy is a 15 to 60 minute medical procedure that is used to examine the entire inner lining of the large intestine, which includes rectum and colon for abnormalities, such as polyps, inflammation, or cancer. A doctor uses a colonoscope, which is a thin, flexible tube with a camera to take images, remove polyps, or take issue samples.

Most health experts, including federal guidelines and the American Cancer Society, recommend that people at average risk for colorectal cancer start screening at age 45. This usually means getting a colonoscopy once every 10 years, or opting for stool-based tests every one to three years. These guidelines also play a role in whether insurance companies cover the tests.

March is the month of colon cancer awareness and with the recent cases of colon cancer patients who are younger than 50. With the death of 48-year-old actor James Van Der Beek due to colorectal cancer, concerns are rising. While cancer death rates overall in people younger than 50may have dropped by 44% since 1990, colorectal cancer has become the leading cause of cancer death in people under 50.

Can Karlyle Morris, section chief for colorectal cancer at MD Anderson Center in Houston tells NBC News, "We anticipate that this is going to be a continued trend."

Even so, most cases of colon cancer are still diagnosed in people over 50. What’s worrying, though, is the steady rise in cases among younger adults in their 20s, 30s and 40s over the past few decades.

Why Does Screening Begin At 45?

Colon cancer typically develops slowly. It often starts as small growths in the colon called polyps, which can eventually turn cancerous if not detected early.

In recent years, growing evidence has pushed experts to reconsider when screening should begin. In 2021, the U.S. Preventive Services Task Force lowered the recommended screening age from 50 to 45. The American Cancer Society had already made a similar recommendation back in 2018.

At the time, the change was not universally accepted. Some in the medical community felt 45 was still too young. Even today, there is ongoing debate.

Setting screening guidelines is not as simple as picking an age. Experts have to weigh the benefits of early detection against potential downsides, including costs, risks from procedures and even practical concerns like taking time off work.

The numbers also tell an important story. For people aged 40 to 44, the risk of colorectal cancer is about 21 cases per 100,000 individuals. That risk more than doubles to 47 per 100,000 between ages 45 and 49, which is one of the reasons screening begins at that point.

Still, younger adults account for a relatively small proportion of cases overall. According to the Mayo Clinic, about 10 percent of colorectal cancer cases occur in people under 50.

The Challenge Of Resources And Awareness

Another key factor is access. There are only so many specialists available to perform colonoscopies, and even now, people can wait months for an appointment.

On top of that, screening rates among younger eligible adults remain low. Only about one in five people aged 44 to 49 are up to date with recommended screenings.

Experts say that if the screening age were lowered further, participation might drop even more. For now, the focus remains on improving awareness and encouraging those already eligible to get screened on time.
