Every year on September 21, World Alzheimer's Day is observed. It is a global effort to raise awareness and challenge the stigma around Alzheimer's disease and other dementia.

Alzheimer's is a severe brain disorder of memory loss and confusion. If it is not diagnosed and managed on time, it can also adversely impact one's mental abilities of learning, thinking, reasoning, remembering, problem-solving, decision-making, and attention.

Every year, a particular theme is followed, this year, the theme is "Time to act on dementia, Time to act on Alzheimer's".

The theme focuses on attitudes towards dementia and addresses the stigma and discrimination that still exists. Some of the common attitudes towards dementia are the common belief that dementia is a normal part of ageing, with 62% of healthcare practitioners actually believing it to be true. 35% of carers had hidden a diagnosis of dementia and 1 out of 4 thought that nothing could be done about it.

History

The first time this day was introduced was in 1994 in Edinburgh, on the occasion of the 10th anniversary of Alzheimer's Disease International (ADI). This organisation was founded in 1984 to support and guide Alzheimer's disease patients and their families.

The organisation also runs Alzheimer's University and aims to connect people around the world to promote Alzheimer's Month, which is also celebrated in September.

What Is Dementia, What Is Alzheimer's?

As per Neha Sinha, Dementia Specialist, CEO and Co-founder of Epoch Elder Care, it is a progressive decline in cognitive abilities, including memory, language, problem-solving and other thinking skills. It is severe enough to interfere with daily life. "It primarily affects older adults, with Alzheimer's being the most common," she says.

Alzheimer's accounts for 60 to 80% of all dementia cases around the world. It is estimated that the prevalence of Alzheimer's worldwide is around 2.4 crores.

While Dementia is the general term for a range of symptoms that affect cognitive abilities, while Alzheimer's is the most common form of dementia.

Shilpi Saraswat, Clinical Psychologist at Sakra World Hospital, Bengaluru points out that the main risk factors of dementia are age, genetics, long-term health conditions, lifestyle choices such as smoking or excessive alcohol use, one's gender and cognitive reserve.

Dementia In Indian Household

Sinha points out that in India, the subtle onset of dementia is quietly emerging as a silent epidemic, affecting millions of households across the country. As per the Neurological Health Atlas of India, 8.8 million elderly are currently living with dementia. "A number that can be doubled by 2036," says Sinha.

Sinha also points out that since its earliest symptoms are often ignored as signs of early ageing, Dementia stays ignored and creeps into the household unnoticed.

"Discovering Alzheimer’s early can be a pivotal moment, offering a window of opportunity that changes the course of the disease. With an early diagnosis, we can initiate medical treatments and a management plan, that may slow down the progression, giving patients and their loved ones more quality time together," says Sinha.

When care is tailored to the person, not just the disease, it profoundly enhances their quality of life. It’s about more than just managing symptoms—it’s about nurturing emotional well-being, maintaining dignity, and providing the support that adapts as the disease evolves.

Can Hearing Loss Lead To Dementia?

While age is one of the risk factors in dementia, Dr Sanjay Sachdeva, a senior ENT at HearClear India suggests a link between hearing loss and dementia.

As per a study by the Lancet Commission on Dementia, untreated hearing loss can give rise to greater cognitive decline and even account for approximately 8% of dementia cases worldwide. This means, 8 lakh of the nearly 1 crore new cases of dementia are diagnosed every year.

"Considering that auditory information plays a pivotal role in forming memories and associations, hearing impairment interferes with the brain’s ability to process auditory information, which consequently deteriorates memory and learning abilities," says Dr Sachdeva. Additionally, hearing loss in ageing people can go beyond the inability to hear things and can contribute to social isolation in them.

What Can Help Reduce It?

Saraswat point out that by modifying 12 risk factors through lifestyle changes, 40% of the dementia cases can be delayed.

Some of the specific actions include maintaining systolic BP of 130 mm Hg or less in midlife from around age 40 years (antihypertensive treatment for hypertension is the only known effective preventive medication for dementia).

Encouraging the use of hearing aids for hearing loss and reduce hearing loss by protecting of ears from excessive noise exposure.

Other such prevention methods include:

• Reduce exposure to air pollution and second-hand tobacco smoke.
• Prevent head injury.
• Limit alcohol use, as alcohol misuse and drinking more than 21 units weekly increase the risk of dementia.
• Avoid smoking uptake and support smoking cessation to stop smoking, as this reduces the risk of dementia even in later life.
• Provide all children with primary and secondary education about brain health.
• Reduce obesity and the linked condition of diabetes. Sustain midlife, and possibly later life physical activity.
• Addressing other putative risk factors for dementia, like sleep, through lifestyle interventions, will improve general health.

Cancer Postcode Lottery will soon be put to an end by the UK Government. Reports say that it will enable the rural population access to cancer specialists and treatments. Before getting into how it will help the rural population and people living in coastal areas to find it easier to see a cancer doctor, let us first understand what postcode lottery means.

What Is Cancer Postcode Lottery?

The term cancer postcode lottery refers to a situation where a cancer patient’s access to the latest and most effective treatments depends on where they live or which hospital they are treated at, rather than purely on medical need.

Based on the information you shared, senior cancer doctors in England are warning that this is happening because of bureaucratic hurdles within the NHS. Even though cancer care is supposed to be equitable across the country, in practice, not all hospitals can easily offer the same treatments.

How Does This Postcode Lotter Work?

Doctors say that some cutting-edge cancer treatments such as advanced radiotherapy techniques and newer immunotherapy drugs require separate funding approvals. Individual cancer centers often have to apply to NHS England for permission and money to use these treatments.

Larger, better-funded hospitals with more administrative resources are often able to navigate this complex system more easily. Smaller or less well-resourced units may struggle, meaning patients treated there may not get access to the same options.

For instance, Stereotactic Ablative Body Radiotherapy (SABR). SABR is a highly precise form of radiotherapy that delivers strong radiation doses directly to small tumors in areas such as the lungs, liver, brain and lymph nodes. Although SABR is a well-established treatment and can be life-saving for certain patients, the Royal College of Radiologists (RCR) says some cancer units still have to apply for special funding to use it. This leads to situations where a patient in one area can receive SABR, while another patient with the same cancer elsewhere cannot.

What Is The Government Planning To Do With Postcode Lottery?

As per the official website of UK Government, this will allow people "living in rural and coastal communities will find it easier to see a cancer specialist as part of plans to tackle the current postcode lottery."

The website notes that most deprived parts of the country have fewer cancer consultants, which leaves patients waiting longer for essential care. These same areas also face highest economic inactivity, with long waits for diagnosis and treatment keeping people out of work and holding back local economies. This is why the government is now introducing "new training places targeted at trusts with biggest workforce gaps, prioritising rural and coastal areas".

Working with the Royal Colleges, the government will encourage more doctors to train in clinical and medical oncology to increase the number of cancer specialists in underserved areas.

These steps will be outlined in the upcoming National Cancer Plan, which aims to speed up diagnosis and treatment, reduce inequalities, and support the goal of making England a global leader in cancer survival, while building a future-ready NHS.

A treatment already popular in the US for skin care, pain relief, and faster healing may soon be known for something far more serious. A new study suggests red light therapy could help protect football players’ brains from chronic inflammation caused by repeated hits to the head.

Experts say the findings are early but promising, especially in the ongoing search for ways to reduce long term brain damage in contact sports.

What Is CTE?

Chronic traumatic encephalopathy, or CTE, is a degenerative brain disease linked to repeated head injuries. It is commonly found in former football players, boxers, and military personnel exposed to blast injuries. Over time, the condition can cause memory loss, confusion, mood changes, aggression, and eventually problems with movement, speech, swallowing, and breathing. There is currently no cure, and doctors still do not know how to slow its progression.

Why inflammation matters in CTE

For now, the only proven way to lower CTE risk is to reduce repeated brain trauma through better helmets, rule changes, and fewer hits to the head. But with more than 100 former NFL players diagnosed with CTE after death and many more suspected cases, experts agree that prevention tools alone are not enough.

Researchers believe chronic inflammation in the brain plays a major role in how CTE develops and worsens over time. If that inflammation can be reduced early, it could potentially limit long term damage.

Red light therapy, also known as photobiomodulation, has already been shown to reduce inflammation in other parts of the body. It works by stimulating energy production inside cells and improving blood flow, which helps tissues repair and recover.

Inside the football study

To see whether the therapy could help the brain, researchers at the University of Utah Health studied 26 collegiate football players during a full season. Half received active red light therapy using a light emitting headset and a small device placed inside the nose. The other half used an identical looking device that did not emit light.

Players completed three 20 minute sessions each week over 16 weeks. Brain scans were taken before and after the season.

The results were striking. MRI scans showed that players in the placebo group experienced a significant increase in brain inflammation by the end of the season. In contrast, those using red light therapy showed little to no increase, with protection seen across most brain regions.

Why experts are paying attention

Specialists who reviewed the findings say the results align with what scientists already understand about inflammation and brain injury. Reducing the inflammatory response after repeated impacts could help limit the damage that builds up over time.

Another advantage is that the therapy is non invasive and does not involve medication. Most users report no major side effects, which makes it especially appealing for athletes.

That said, experts caution against buying over the counter red light devices. The therapy requires very specific wavelengths that can penetrate skin and tissue effectively. Many consumer products do not meet those standards.

Researchers stress that more studies are needed to confirm long term safety and effectiveness. A large Department of Defense funded trial is already planned, involving 300 people with persistent concussion or traumatic brain injury symptoms, including veterans and first responders.

If future research continues to show benefits without harm, red light therapy could one day become part of how teams protect athletes’ brains, not just in football, but across many sports.

Nicole "Snooki" Polizzi opened up about a cancer scare. Now, 38, the Jersey Shore star, posted on her TikTok an emotional video, where she explained that she has been dealing with abnormal pap smear results. She said that it has been about four year since the precancerous cells were found. Because of that she had to undergo an "uncomfortable" colposcopy and biopsy.

She said that when the results came back, the doctor informed her that her cervix is "Not looking great". The doctor had found cancerous cells on the top of her cervix. She said that she would soon need a cone biopsy under anesthesia for further testing. "I am terrified. It is scary, but we have to get it done because cervical cancer is nothing to joke about."

She said, "But whatever to keep me healthy and safe to be here for my kids that I have now," referring to her three children with her husband Jionni LaValle.

In her TikTok video, she said that she is scared and freaking out. She also said that she hopes to find community on social media with other women who have been through the same.

She also agreed to delaying her routine examination because of fear. "I waited on my appointments because I knew I might not get great results but also because I didn't want to feel the pain. I didn't want to deal with the stress of having to deal with all of this," she said.

Talking about her TikTok video, she said, “Just making this video to spread awareness to make sure you get your pap smears. And if your doctor calls you to do it again, do it, Make sure you are fine and prevent all the bad things that could happen, like cervical cancer." She said she was nervous but also shared that she received a lot of support from her friends and family. "Being a woman is not easy and is definitely a scary thing. I know I am going to be fine. It is just scary."

What Is Cervical Cancer?

Cervical cancer develops in a women's cervix (uterus opening) due to abnormal cell growth, primarily caused by persistent HPV infection, a common infection that's passed through sexual contact.

When exposed to HPV, the body's immune system typically prevents the virus from causing damage however, in a small percentage of people, the virus can survive for years and pave the way for some cervical cells to become cancerous.

Treatment involves surgery, radiation, and chemotherapy, with early detection significantly improving outcomes, though it remains a major cancer in low-income countries. Cervical cancer can also be prevented through vaccination and regular screening (Pap/HPV tests).

Dr Ninad Katdare told News18: "In its early stages, it is often more of a whisper than a shout. As a cancer surgeon who has treated hundreds of women with gynaecological cancers, I can say with confidence that recognizing these subtle cues can lead to earlier diagnosis and significantly better outcomes."
