Experiencing daytime sleepiness is something that is usually perceived as a minor inconvenience, but for older adults, it could be an early warning sign of Dementia. This neurodegenerative disease leads to the progressive decline of brain cells. This eventually

affects memory, cognition, and personality, making everyday tasks more difficult. As one of the fastest-growing neurological disorders across the world, dementia poses a significant health threat to ageing populations.

Is Dementia Linked To Poor Sleep?

For this study, researchers followed 445 older adults (average age 76) over three years, aiming to determine whether poor sleep could increase the risk of mild cognitive impairment (MCI), which often leads to dementia. At the start, none of the participants had MCI, but by the end of the study, 36 individuals had developed the condition.

The researchers discovered that participants with poor sleep were more likely to develop MCI compared to those who slept well. However, when depression symptoms were taken into account, the link between poor sleep and MCI became less pronounced, suggesting that while sleep issues are a concern, mental health also plays a key role in dementia risk.

To assess sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used, evaluating factors such as sleep duration, disturbances, and daytime alertness. Among these, "daytime dysfunction"—defined as excessive sleepiness and low energy during the day—was most strongly associated with an increased risk of MCI. Those experiencing daytime dysfunction were more than three times as likely to develop MCI as those who didn’t report such symptoms.

There are many types of dementia:

Dementia is not a specific disease. According to the Centers for Disease Control and Prevention (CDC), it is an overall term that describes a decline in mental ability that interferes with daily life. People with dementia often have symptoms like trouble remembering, thinking, or making everyday decisions. These symptoms tend to get worse over time.

Alzheimer’s disease is the most common type of dementia, and it mostly affects the elderly. Each form of dementia has a different cause. Though dementia mostly affects older adults, it is not a part of normal ageing. An estimated 6.7 million older adults have Alzheimer's disease in the United States. That number is expected to double by 2060, as per data from the CDC.

In 2022, 3.8% of men and 4.2% women in US were diagnosed with dementia. The percentage of people increase with age from 1.7% for those aged 65-74 to 13.1% for those aged 85 and older. Alzheimer's accounts for 60 to 80% of all dementia cases and it is most prevalent in California, Florida, and Texas, as these states have the highest number of people.

Cancer screening for UK's second deadliest cancer is undergoing some changes, as NHS UK lowers the threshold of bowel cancer test. What it means is that NHS England is lowering the threshold of the amount of blood detected through a Fit or Fecal immunochemical test, needed to trigger the patient being sent for further investigation.

What Is the Fit Test?

The fecal immunochemical test is used to detect bowel cancer by spotting blood in the patient's stool. As per the new NHS guidelines, the sensitivity of the Fit test will be increase as part of an overhaul of cancer diagnosis as well as treatment.

As of now, it stands at 120 micrograms of blood a gram of stool, however, it will be reduced to 80 microgram by 2028. This will bring England into line with threshold that are already followed in Scotland and Wales.

“This is a major step forward in bowel cancer detection and will help save hundreds more lives from this devastating disease,” said Prof Peter Johnson, NHS England’s national clinical director for cancer. “Testing at a lower level threshold will now provide a better early warning system for bowel cancer, helping us to spot and treat cancers earlier, often picking up problems before symptoms occur," as reported by The Guardian.

Bowel Cancer In The UK

Around 44,100 people in the UK are diagnosed with bowel cancer each year, and about 17,400 die from the disease, making it the second leading cause of cancer deaths. Risk factors include processed meat consumption, excess weight and alcohol use. Cancer Research UK estimates that 54 percent of cases could be prevented. “Once fully implemented testing at the lower level threshold is expected to reduce late stage diagnoses and deaths from bowel cancer by around 6%,” NHS England said.

The estimate suggests that improving prevention and earlier detection could save the health service £32 million each year. The change is expected to result in around 600 additional bowel cancer diagnoses annually in England, an 11 percent rise on top of the 5,320 cases currently identified each year through the existing test.

Under the changes, the NHS is expected to carry out 35 percent more colonoscopies for patients flagged as high risk by the Fit test. Introduced in 2019, the Fit test is a home screening programme in which eligible people receive a kit by post, return a small stool sample, and have it analyzed in a laboratory.

The expansion will be detailed in the government’s new national cancer plan, set to be launched on 4 February, which cancer groups observe as World Cancer Day. In England, eligibility was widened in 2024 to include people aged 50 to 53, down from the earlier range of 54 to 74. During 2023–24, nearly seven million kits were sent out, with 68 percent returned, leading to the detection of 5,320 cancers. With the broader age criteria, an additional 1.2 million people are now being offered the test.

What Is Bowel Cancer?

The Cancer Council notes that bowel cancer is also called the colorectal cancer, colon cancer or rectal cancer, which develops in the inner lining of the bowel. It is preceded by growths called polyps, which could become invasive cancer if undetected.

Measles, a disease once eliminated is making a come back. In the US, the disease has made a full-fledged come back and now the UK has also lost its measles elimination status. The World Health Organization (WHO) announced this news based on the spread of cases in 2024, when there were 3,600 suspected cases. Elimination status means that there is no sustained transmission, this is why this decision was expected given the scale of outbreaks in 2024.

Measles In UK: Cases Have Gone Up

Even in last year, 2025, there were more than 1,000 cases. Moreover, like the US, in the UK too the rate of vaccination fell. It was reported by the BBC that vaccination rates were below 95% threshold required to achieve herd immunity. This is when enough people in a community have been vaccinated against the disease, so it is harder for the pathogen to spread.

Measles Free UK

It was in 2017, when UK, for the first time, was declared measles free. However, it lost its status two years later. However, measles spread was halted completely in 2021, gaining its measles free status back. The key to elimination was social distancing during the pandemic.

Measles In UK: How Did It Lose Its Status?

In late 2023, measles outbreaks were reported in the UK, which led to a surge in cases in 2024. Vaccination uptake at the end of 2024 was 92% for the first dose, however, for the second dose, it was below 82%.

Dr Vanessa Saliba, consultant epidemiologist at UKHSA said, "Infections can return quickly when childhood vaccine uptake falls - measles elimination is only possible if all eligible children receive two MMRV doses before school. The NHS is making vaccination easier, including offering the second MMRV dose earlier at a new 18-month appointment to boost uptake and support elimination goals."

She also noted that children and adults must get vaccinated as NHS also offers catch-up jabs.

Dr Baharat Pankhania, from the University of Exeter, as reported by the BBC said, "Measles is an infection that can be prevented by vaccine - and it's extremely concerning that in the UK we now have pockets of low or no vaccine uptake. We urgently need to remedy this situation." Pankhania also noted that there is a need to make the access to GPs easier, and for an effort that could immunize babies in their homes and counter wrong information around vaccine safety.

What Is Measles?

Measles, also known as rubeola, is an extremely contagious viral illness that typically causes high fever, cough, runny nose, red and watery eyes, and a characteristic rash that begins on the face and spreads downward across the body. It spreads through respiratory droplets and can lead to severe and sometimes fatal complications, including pneumonia and inflammation of the brain known as encephalitis.

Although it is preventable through the safe and effective MMR vaccine, measles remains a serious threat in many regions. There is no specific cure, and treatment focuses on managing symptoms, according to the Cleveland Clinic.

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.
