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?

Daytime sleepiness is a direct result of poor sleep quality. Now, a recent research, published in the journal Neurology, highlighted a potential link between poor sleep and the development of dementia, particularly a condition called motoric cognitive risk syndrome (MCR). The study found that 35.5% of participants who reported extreme daytime sleepiness developed MCR, which is a precursor to dementia.

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.

Colorectal Cancer Testing: New Guidelines To Help Millions Of Americans

Updated May 27, 2026 | 08:00 PM IST

The American Cancer Society (ACS) has updated its colorectal cancer testing guidelines, which bring new screening options for colorectal cancer. This will give the Americans two new options of stool-based tests and blood-based screening tests.

The ACS recommended colorectal cancer screening for citizens as the risk of the disease starts at the age of 45 and continues through age 75 for those with a life expectancy of 10 more years. Thus, to make colorectal cancer tests more accessible to the masses, the new guideline gives nod to blood-based screening tests and FDA-approved new stool sample kits.

Blood-based screening tests must be done in a doctor's office, while one can use stool sample kits for testing at home. Notably, colonoscopy is still the most accurate option for detecting colorectal cancer.

The new guidelines acknowledged the fact that people are likely to choose the most effective colorectal cancer screening test. But still about 20 million eligible Americans remained untested, according to the ACS.

ACS mentions that 1 in 5 colorectal cancer cases is seen in young adults; the new guidelines were a direct result of this huge problem. Though the one who will choose colonoscopy would only have to go through screening every 10 years, on the other hand, the gap between screenings will be every one, three, or five years, depending on the specific method of testing selected.

Early Symptoms Of Colorectal Cancer

Some of the most commonly missed early signs include:

  • Persistent changes in bowel habits, especially if they last more than a few days, must be taken seriously. Narrow or ribbon-shaped stools may indicate a tumor partially blocking the colon.
  • Blood in the stool is one of the most common and concerning signs. While it might be due to hemorrhoids or fissures, it’s important not to assume. A proper evaluation is critical.
  • Unexplained weight loss: Especially when unintentional.
  • Abdominal cramps or bloating: Misinterpreted as common digestive issues.

Ignoring such a red flag delays diagnosis and drastically reduces treatment success rates. A timely visit to a healthcare provider can change outcomes.

How To Prevent Colorectal Cancer?

  • Diet: More fibre-rich fruits, vegetables, and whole grains; less processed food and red meat.
  • Physical activity: “Even 30 minutes of daily walking helps.”
  • Screenings: Especially vital for those over 45 or with a family history.

Sri Lanka is facing a meningitis outbreak, and according to the Health Promotion Bureau of Sri Lanka, 200 people have been infected by this virus. As of now, about 50 people are getting treatment at the hospitals across four districts.

The disease was first found among a group of school goers in the Deniyaya area before spreading to other areas, including Diyatalawa, Welimada, and Rikillagaskada. The health authorities of the island nation have already issued special guidelines to stop the spread of the disease.

The authorities there said the disease mainly spreads through contaminated food and water, and it can also be transmitted through droplets released when an infected person coughs or sneezes, as well as through close contact. The citizens were also asked to drink boiled water and avoid crowded places.

The Health Ministry of Sri Lanka has appointed a special team consisting of virologists and epidemiologists to conduct observations on the viral meningitis condition reported from the Central and Southern provinces and to identify its viral transmission pattern.

“Though the cases show signs of meningitis, they have rarely progressed to encephalitis, a potentially life‑threatening inflammation of brain tissue, as the virus itself is self-limiting, allowing the immune system to overcome the ailment,” the deputy minister, Dr. Wijeyamuni, said.

What Is Meningitis?

Meningitis is an infection of the protective membranes around the spinal cord and the brain. It can become very serious if not treated or diagnosed in time. It is a consequence of bacterial or viral infection. Despite being a rare occurrence, the infection can spread through coughs, sneezes, a cold, or physical contact in the form of kissing.

Understanding the symptoms, causes, and treatment options is important for early diagnosis and timely medical care.

Symptoms Of Meningitis

Health officials urged the public to remain alert to the warning signs of meningococcal meningitis. Common symptoms include:

  • Rash
  • Headache
  • Neck stiffness
  • Fever
  • Drowsiness
  • Nausea or vomiting
  • Increased sensitivity to light

How is Meningitis Diagnosed?

Physicians diagnose meningitis using a combination of clinical presentation, laboratory examinations, and imaging tests. Important diagnostic tests are Lumbar Puncture (Spinal Tap), Blood Cultures, and Imaging (CT or MRI Scans).

US President Donald Trump has declared himself to be in good health after undertaking the third annual medical check-up in his second term as the oldest American President.

Trump, who turns 80 next month, saw his doctors at the Walter Reed National Military Medical Center for a routine health check up on May 26.

“Everything checked out PERFECTLY,” Trump wrote on social media. He has, however, offered no details about what doctors observed.

The White House hasn't so far released details from Trump’s health check up to support his claim, or clarify what tests the president had undergone as part of the clinical exam.

As per an earlier statement from the White House, the visit involved “routine annual dental and medical assessments as part of his regular preventive health care,” but did not offer additional details on the medical exam.

His previous annual check-up was in April 2025. In October, he underwent another check-up.

“You have five doctors sitting there and … the questions are very easy at the beginning, then pretty easy, then pretty hard by the time you get to the end, there are not a lot of people in the room who can get them, believe me,” Trump informed the crowd at a rally in New York state last week about the impending test, The Times reported.

“So the first question was, you have a bear, a snake, an elephant, and a horse. Name the horse. That’s the horse. The second question is a little tougher,” he said.

“Toward the end, they had a question like, pick a number, sir, any number. OK. 203. Multiply times nine, divided by two, add 1324, subtract 1292. Sir, multiply it out one more time by 19. What is the answer, sir? I got it right … and the one doctor said, I’ve been doing this test for 20 years, I’ve never seen anybody ace it. … So I’ve taken it, and I’ve aced it all three times, I’ll tell you, because it is a positive thing.”

The president’s health has been the subject of intense scrutiny — ranging from his mental state to visible bruising around his hands.

Trump — who has frequently criticized former President Joe Biden over age-related health and fitness issues — has recently remarked on how good he feels despite his age.

Trump said he feels the same as he did 50 years ago. “I feel literally the same,” he said at an Oval Office event. “I don’t know why. It’s not because I eat the best foods,” AP reported.

He also joked about his exercise regimen, saying that he works out “like about one minute a day, max.”

According to a White House summary of his previous annual medical examination in April last year, Trump was found to be in “excellent cognitive and physical health”.

“A comprehensive neurological examination revealed no abnormalities in his mental status, cranial nerves, motor and sensory functions, reflexes, gait, and balance. Cognitive function, assessed using the Montreal Cognitive Assessment (MoCA), was normal with a score of 30 out of 30,” his White House physician, Captain Sean Barbabella, wrote.

There were tests for depression and anxiety, and Trump recorded a score “within the normal range for both,” although numbers were not given.

Scans in October also demonstrated that Trump is in “excellent overall health”.
