Glaucoma is also called the "silent thief of sight" since it progresses slowly without apparent symptoms in its initial stages. Glaucoma develops quietly, unlike other vision issues that appear with instant discomfort or blurred vision, and tends to damage peripheral vision before central vision. Regular eye exams are important for early diagnosis and treatment.

Think of your eyes as cameras, taking pictures that your brain interprets through the optic nerve. Glaucoma destroys this nerve, preventing your brain from getting clear pictures. The catch is that it happens slowly and painlessly, so it's easy to ignore until permanent vision loss has taken place.

Dr. Ajay Sharma, Ophthalmologist, says, "Most people think that good central vision means healthy eyes, but glaucoma attacks the optic nerve, producing slow, irreversible damage. Early detection is the key to identifying this condition before it advances."

Early Symptoms of Glaucoma Are Often Undetectable

Perhaps the most perilous part of glaucoma is that there are often no warning signs at all. Most individuals believe that vision loss will be preceded by obvious symptoms such as pain or sudden blurriness, but this is not true for glaucoma. The disease tends to attack peripheral vision initially, so it is hard to notice until extensive damage has been done. With time, people might start to feel they cannot see things on the side, but by then, the damage could already be extensive.

From Dr. Sharma, "Glaucoma may develop even when vision seems perfectly normal. Sometimes, for example, with normal-tension glaucoma, optic nerve damage happens even with normal intraocular pressure."

Who's at Risk? Kow Risk Factors

While anyone can get glaucoma, some people are at greater risk. Knowing these risk factors can help you take action to safeguard your eyesight.

Age: The risk of glaucoma grows much higher after age 60. African Americans are at greater risk, however, after age 40.

Family History: If a close relative has experienced glaucoma, you are more likely to develop it.

Ethnicity: African Americans, Hispanics, and Asians are more likely to develop certain forms of glaucoma.

Eye Health Conditions: Nearsightedness, eye trauma, or chronic inflammation can lead to the disease.

Medical Conditions: Glaucoma risk is heightened in people with diabetes, high blood pressure, and heart disease.

Medications: Chronic use of corticosteroids will often elevate intraocular pressure, elevating the danger of optic nerve damage.

How Can You Catch Glaucoma Early?

As glaucoma has limited detectable signs and symptoms during the early phases, the optimal approach to capture it before severe harm is by extensive eye examinations.

Opticians conduct a dilated eye test, during which special drops widen the pupils, enabling a better look at the optic nerve. A tonometry test takes an intraocular reading, and a visual field test checks peripheral vision.

Dr. Sharma stresses, "Those with increased risk factors, such as high myopes or hypermetropes, diabetes, eye injuries, or long-term steroid treatment, should have regular eye tests to check intraocular pressure and optic nerve function."

How to Protect Your Eyesight?

Though glaucoma cannot be cured, early detection can delay its advancement and help save vision. Here are real-life measures to safeguard your eyesight:

1. Get Regular Eye Exams

A thorough eye examination every one to two years is necessary, particularly for people over 40 or with risk factors. These examinations can identify glaucoma before symptoms are evident.

2. Control Underlying Health Conditions

Managing conditions such as diabetes and high blood pressure can lower the risk of optic nerve damage. Healthy living protects your overall eye health.

3. Take Medications as Directed

If diagnosed with glaucoma, your doctor may prescribe eye drops or oral medications to reduce intraocular pressure. Consistently using prescribed treatments can slow disease progression.

4. Protect Your Eyes from Injury

Eye injuries can increase the risk of glaucoma. Wear protective eyewear during activities that pose a risk, such as sports or working with hazardous materials.

5. Follow a Healthy Diet

Eating food rich in nutrients, especially antioxidants, omega-3 fatty acids, and vitamins A, C, and E, is good for your eyes. Make leafy greens, fish, nuts, and oranges a part of your diet.

6. Be Physically Active

Regular exercise may reduce eye pressure. Walk, practice yoga, or swim to stay healthy.

7. Reduce Screen Time and Eye Strain

Prolonged screen time can cause digital eye strain, leading to discomfort and dry eyes. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.

Glaucoma is a quiet but dangerous eye disease that can cause permanent vision loss if not treated. Because symptoms may not be noticeable until extensive damage has been done, regular eye exams are the best protection against this disease.

As Dr. Sharma says, "The key to preventing glaucoma-related vision loss is early detection. Don't wait for symptoms to appear—schedule an eye exam and take charge of your eye health today."

Aging is a significant factor in memory loss and cognitive decline. Now, a team of US researchers has pinpointed a single protein that drives these changes in the brains of the elderly.

In aging mice, higher levels of protein FTL1 weakened connections between brain cells, leading to memory decline.

But when FTL1 was reduced, the brain began to recover. It also rebuilt lost connections and restored memory performance, according to the study, published in Nature Aging.

"It is truly a reversal of impairments," said Saul Villeda, Associate Director at the University of California - San Francisco's Bakar Aging Research Institute and senior author of the paper. "It's much more than merely delaying or preventing symptoms."

While the research was carried out in aging mice, it holds immense potential for human brain function.

FTL1: A Key Driver Of Brain Aging

In the study, the researchers tracked shifts in genes and proteins in the hippocampus of mice. The FTL1 protein appeared consistently different between young and old animals.

Compared to young mice, the older mice showed higher levels of FTL1. They also had fewer connections between neurons in the hippocampus and performed worse on cognitive tests.

Increasing FTL1 levels in young mice produced brain changes similar to those seen in older mice. The researchers found that this change occurs because of alterations in the way nerve cells produce FTL1 protein.

In older mice, the nerve cells that produced high amounts of FTL1 developed simplified structures, forming short, single extensions instead of the complex, branching networks seen in healthy cells.

Further experiments showed that in older mice, higher levels of the protein slowed cellular metabolism in the hippocampus -- the part of the brain responsible for learning and memory.

However, when researchers treated these cells with a compound that boosts metabolism, the negative effects were prevented.

A Promise For Future Brain Aging Therapies

Villeda believes these findings could pave the way for treatments that target FTL1 and counter its effects in the brain.

"We're seeing more opportunities to alleviate the worst consequences of old age," he said. "It's a hopeful time to be working on the biology of aging."

Cancer treatment has long been thought to be unsuccessful among people of advanced age, and older adults are often left out of clinical decisions.

While they may face more surgical complications, a new study proved that even people aged over 80 can still safely have surgery and be cured. It showed that the overall health of a patient matters more and that age must not be the only criterion to rule out surgery.

The study, published in The Lancet Regional Health – Americas, showed that surgery for lung cancer is safe in elderly patients aged 80 and above, especially when the cancer is in an early stage.

Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center in the US found that they can recover like young cancer patients as well as live longer like them.

“As our population ages, more patients over 80 are being diagnosed with early-stage lung cancer, yet they are often not considered for surgery,” said Raja M. Flores, Chair of the Department of Thoracic Surgery at Mount Sinai Health System.

“Our findings show that when patients are carefully selected based on their overall health, not just their age, they can tolerate surgery well and experience excellent long-term outcomes,” he added.

What Did The Study Find?

The study findings are based on a study of 884 patients with early-stage lung cancer, including 114 people who were age 80 or older.

The researchers examined surgical outcomes and quality of life in patients with early-stage non-small cell lung cancer, comparing those aged 80 and older with younger patients.

The results showed that older patients lived just as long as younger patients after surgery. While some older patients had more complications right after surgery, most patients in both groups felt better over time, and their quality of life improved within a year.

The study noted that early detection in older patients may be key. The researchers called for screening guidelines to include patients who are over 80 years old based on these findings.

What Is Lung Cancer?

Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.

According to the American Cancer Society, lung cancer mainly occurs in older people. Most people diagnosed with lung cancer are 65 or older; a very small number of people diagnosed are younger than 45.

The average age of people when diagnosed is about 70.

It is also the leading cause of cancer death in the US, accounting for about 1 in 5 of all cancer deaths.

In many cases, there are no symptoms; however, one must look out for these:

• a persistent cough
• coughing up blood
• persistent breathlessness
• unexplained tiredness and weight loss
• an ache or pain when breathing or coughing.

The two main types of lung cancers are:

Non-small-cell lung cancer (NSCLC): This is the most common form, making up about 80–85% of all cases. NSCLC includes three subtypes:

• Squamous cell carcinoma
• Adenocarcinoma
• Large-cell carcinoma

Cancer is not just a problem of elderly people anymore. In India, there has been an increased number of cases where individuals under the age of 40 are diagnosed with various forms of cancer. Even if there are fewer cases of this medical condition among younger people, this fact does not change the fact that one-fifth of all cancer patients in India are younger than 40 years.

Breast cancer, colorectal cancer, head and neck cancer, as well as blood cancer, are some types of cancer that become more common at a younger age. Among the most alarming statistics, the incidence of colorectal cancer in people aged 30-40 should be mentioned. Moreover, the fact that breast cancer becomes evident nine years earlier in Indian women in comparison with Western women must also be noted.

What Makes This Problem Increase?

There is a wide variety of factors that contribute to this problem. These are the following:

• Lifestyle changes, such as lack of exercise, unhealthy eating habits, being overweight, and stressful situations
• Alcohol and tobacco consumption
• Pollution in the urban environment
• Problems with early diagnosis due to the negligence of patients
• Low screening rates among the young population

Early detection saves lives. Some warning signs to look out for are:

• Sudden and unexplained weight loss
• Endless fatigue
• Digestion issues
• Breast lumps or any swellings anywhere in the body
• Coughing or trouble swallowing persistently

Why Late-stage Diagnosis Is Even More Serious

Not only does it take time to diagnose cancer cases in young patients due to low suspicions, but these cancers also create an additional burden on people during their prime earning period.

How To Combat This Trend

There needs to be a paradigm shift in our understanding of this problem. First of all, we have to understand that cancer affects patients irrespective of their age, and therefore, when you experience some symptoms of cancer, do visit a doctor to get your condition checked out.

The key is maintaining healthy practices like balanced nutrition, exercising, not smoking, and limiting consumption of alcohol.
