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.

The Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda, caused by the Bundibugyo virus, has reached 952 confirmed cases and 247 deaths, according to the latest update from the Africa Centres for Disease Control and Prevention (Africa CDC).

As of June 18, the DRC accounts for 933 confirmed cases and 245 deaths, while Uganda has reported 19 confirmed cases and two deaths. Uganda has not shown the same level of sustained transmission seen in

the DRC.

The overall case fatality rate currently stands at 25.9 per cent.

The outbreak caused by the Bundibugyo virus currently has no approved treatment or vaccine, complicating efforts to contain the disease.

Ituri Province Remains The Epicenter

Ituri Province continues to be the hardest-hit region, accounting for approximately 91 per cent of all confirmed cases. The main hotspots include Bunia, Rwampara and Mongbwalu.

Health officials are also concerned about North Kivu, where the case fatality rate has reached 58.4 per cent, with high mortality reported across several affected health zones.

The outbreak has now spread to 34 health zones in the DRC and one district in Uganda. In the DRC, the most affected provinces are Ituri, North Kivu and South Kivu. In Uganda, cases have been reported mainly in Kampala, including both imported and locally transmitted infections, the CDC said.

The CDC said response teams continue to expand surveillance, case management, infection prevention and control measures, laboratory testing, border screening, risk communication and community engagement activities.

A new laboratory in Aru, Ituri Province, has become operational, increasing the total number of Ebola testing sites to six.

Despite ongoing efforts, the response remains under significant strain. Treatment centres are operating beyond capacity, with bed occupancy reaching 102% and 349 patients currently admitted across affected health zones.

The CDC also reported several operational challenges, including delays in patient referrals, shortages of ambulances and vehicles, gaps in personal protective equipment (PPE), and limited access to some affected areas.

Contact Tracing Challenges Persist

Surveillance and contact tracing teams continue to face obstacles, including incomplete addresses, delayed investigations and difficulties accessing certain communities.

More than 7,200 contacts have been identified across the two countries and are being monitored, the CDC said.

Africa CDC also estimates that $21.5 million is urgently needed to address critical gaps in the outbreak response.

Outbreak Outpacing Response Efforts

The outbreak's impact has been particularly severe among vulnerable populations. Last week, another six-month-old girl died from Ebola. She was the third child to die at an orphanage in eastern Congo during the current outbreak.

"It has been a month after the Ebola outbreak and it is still outpacing our response efforts. There are big gaps in surveillance, diagnosis, contact tracing and community engagement," said Dr. Kerry Dierberg of Doctors Without Borders (MSF), which is helping lead medical response efforts in Congo, the Indian Express reported.

Public health experts warned that the outbreak is spreading faster than health authorities can detect and contain it.

Many infected individuals are not reaching hospitals or health centers and may be dying without being identified as Ebola cases. As a result, health workers are struggling to determine the true scale of transmission, increasing the risk of further spread within the region, NPR reported.

Yoga helps people live a balanced life and is an expression of the human spirit, Prime Minister Narendra Modi said on Sunday while leading the 12th International Day of Yoga celebrations from Kolkata.

"From physical wellness to inner peace, yoga enriches every aspect of life. Delighted to join this year’s celebrations in Kolkata," PM Modi said, in a post on social media platform X.

Addressing a large gathering, PM Modi said yoga has evolved into the world's largest community celebration, bringing together people across countries, cultures, and generations.

"June 21, the longest day of the year in the Northern Hemisphere, is now recognized worldwide as a day of yoga," he said.

"Yoga brings people together. I congratulate people across the world on this occasion. Yoga is not just physical exercise, nor is it restricted to any age group. It is an expression of the human spirit," the Prime Minister added.

Yoga Day Theme: Healthy Ageing

The theme for International Day of Yoga 2026 is "Yoga for Healthy Ageing," highlighting yoga's role in promoting physical health, mental well-being, emotional resilience, and active ageing, thereby improving overall quality of life.

PM Modi emphasized that yoga is a powerful tool for fostering both personal well-being and social harmony.

Meanwhile, United Nations Secretary-General Antonio Guterres also extended greetings on the occasion of International Day of Yoga.

In a post on X, Guterres highlighted yoga's global appeal and its contribution to physical and mental well-being.

"From its deep roots in ancient India, yoga has become truly universal, helping millions of people of all faiths and cultures find calm, build strength, and live with purpose," he said.

A Global Movement Rooted in Ancient India

Over the years, International Day of Yoga has grown into a global movement, serving as a cultural bridge that connects people across continents. The word "yoga" is derived from the Sanskrit term yuj, meaning "to join" or "to unite," reflecting its essence of harmonizing the body, mind, and spirit.

The experts stressed the urgent need to tackle India's growing obesity crisis—particularly among children.

Speaking during a panel discussion on the future of women's and child healthcare, Dr. Sivaranjani Santosh, often referred to as the "ORS Lady of India," praised India's public health achievements, including the successful Pulse Polio Program, malaria control efforts, and improvements in child nutrition.

However, she cautioned that new challenges now threaten the country's health gains.

"There were many things we are lagging a bit also," Dr. Santosh said, stressing the need for fair food labelling, responsible marketing, and stricter regulation of irrational drug combinations.

She issued a stark warning about unhealthy eating habits, saying, "This junk food pandemic, this is where India needs to really, really focus on. Childhood obesity is a pandemic now. And it's like do or die right now for us."

Her comments highlighted growing concerns that poor nutrition and processed foods are driving obesity among children, increasing their risk of chronic illnesses later in life.

Echoing the concerns, Dr. T. Rajeshwari Reddy, Senior Consultant Obstetrician, Gynecologist, and Laparoscopic and Robotic Surgeon at Continental Hospital, explained that unhealthy lifestyles beginning in childhood are now contributing to a rise in hormonal disorders, infertility, and high-risk pregnancies.

"We are seeing a lot of people with hormonal imbalances and a lot of issues from teens, and that is what gets translated into infertility and high-risk pregnancy," she said.

Dr. Rajeshwari stressed that prevention must begin early. "The beginning has to be from birth only," she said, urging families to prioritize home-cooked meals, healthy routines, adequate sleep, and reduced screen time. She added that preventive healthcare should become the foundation of India's health strategy over the next decade.

Experts agreed that the future of Indian healthcare will depend on preventive medicine, technology, artificial intelligence, and stronger public-private partnerships to improve access to healthcare, particularly in rural areas.

They urged that India's fight against childhood obesity and lifestyle-related diseases must begin at home, with healthier food choices, greater awareness, and prevention from an early age.

Meanwhile, the AI in healthcare panel featured Prof. Renu John, IIT Hyderabad; Nishan Ali, Founder & CEO, Neurologic AI; Dr. Rahul Sawakhande, CEO, Aakaar Medical Technologies; and Dr. Rajah V.
