An experimental treatment happens to be the solution to delay Alzheimer's symptoms in some people. These people are the ones who are genetically destined to get the disease in their 40s or 50s. These new findings form ongoing research has now been caught up in Trump administration funding delas. The early results of the study has been published on Wednesday and the participants too are worried that politics could cut their access to a possible lifeline.

One of the participants had said, "It is still a study but it has given me an extension to my life that I never banked on having." The participant is named Jake Henrichs, form New York City, who is 50 years old. He is one of them to be treated in that study for more than a decade now and has remained symptom-free despite inheriting an Alzheimer's-causing gene that had killed his father and brother around the same age.

Slowing Down The Symptoms

Two drugs which can modestly slow down early-stage Alzheimer's are sold in the United States. These drugs clear the brain of one of its hallmarks, a sticky gunk-like part called the amyloid. However, there have not been any hints that removing amyloid far earlier, way many years before the first symptoms appear, may postpone the disease.

How Was The Research Conducted?

The research is led by Washington University in St Louis, which involved families that passed down rare gene mutation as participants. This meant it was almost guaranteed that they will develop symptoms at the same age their affected relatives did.

The new findings is based on a subset of 22 participants who received amyloid-removing drugs the longest, on average eight years. Long-term amyloid removal cut in half their risk of symptom onset. The study is published in the journal Lancet Neurology.

Washington University's Dr Randall Bateman, who directs the Dominantly Inherited Alzheimer's Network of studies involving families with these rare genes says, "What we want to determine over the next five years is how strong is the protection. Will they ever get the symptoms of Alzheimer’s disease if we keep treating them?”

The researchers before though did not know what exactly caused Alzheimer's which affects nearly 7 million Americans, most of them in their later life. However, it is clear that these silent changes occur in the brain at least two decades before the first symptom shows up. The big contributor. At some point amyloid buildup can trigger a protein named tau that then starts to kill neurons, which can lead to cognitive decline.

Researchers are now thus studying the Tau-fighting drugs and are looking into other factors, like inflammation, brain's immune cells and certain virus.

The National Institute of Health (NIH) has expanded its focus as researchers have found more reasons for Alzheimer's. In 2013, the NIH's National Institute on Aging funded 14 trials of possible Alzheimer's drugs over a third targeting amyloid. By last fall, there were 68 drugs and 18% of them target amyloid. However, there are scientists too who think that amyloid is not everything and their is way more in the brain tissue, immune cells, and more which can be studied.

As Delhi and most of North India continue to face rising temperatures, doctors have raised concerns over worsening air pollution, warning that the combination is placing severe stress on the human body, even among otherwise healthy individuals.

HealthandMe spoke to experts to understand how the overlap of heatwaves and polluted air can affect health.

According to experts, extreme heat and pollution together are no longer just an environmental issue, but are emerging as a serious urban health emergency.

Dr. Amit Kumar Mandal, Senior Director - Pulmonology at Paras Health, explained that extreme heat combined with pollution forces multiple organs to work harder simultaneously.

“People often think heatwaves only affect the skin or cause dehydration, but when extreme heat combines with high pollution levels, the body starts functioning as if it is constantly under attack,” he said.

The expert explained that "the lungs are forced to work harder to filter hot, polluted air, while the heart simultaneously struggles to regulate body temperature. This invisible overload can quietly trigger inflammation, breathing distress, sudden BP fluctuations, and cardiac strain, even in people who otherwise consider themselves healthy".

Symptoms Often Missed

Dr. Amit further noted that the subtle symptoms in the beginning often go unnoticed, making the combination even more dangerous.

The symptoms increasingly being seen during such weather conditions include

  • persistent tiredness,
  • irritability,
  • disturbed sleep,
  • headaches,
  • chest heaviness,
  • unusual breathlessness.

“Heat and pollution together are no longer just an environmental issue; they are emerging as a serious urban health emergency. Preventive care during summers now has to go beyond avoiding the sun; people need to actively protect their respiratory and cardiovascular health as well,” Dr. Amit told HealthandMe .

How Prolonged Exposure Can Affect Health

Dr. Rahul Punj, Senior Consultant - Internal Medicine at Yatharth Super Speciality Hospital, told HealthandMe that prolonged exposure to high temperatures and poor air quality can affect multiple systems in the body.

“Rising heat and increasing pollution levels are becoming major health concerns, especially in urban areas. Prolonged exposure to extreme temperatures and poor air quality can lead to dehydration, heat exhaustion, breathing difficulties, allergies, skin issues, and can even worsen heart and lung diseases. Children, elderly people, pregnant women, outdoor workers, and patients with asthma, COPD, or other chronic illnesses need to be extra cautious during this period,” he said.

Dr. Rahul advised people to take preventive measures seriously during heatwave conditions. Preventive measures that can help reduce health risks include:

  • staying hydrated,
  • avoiding direct sunlight during peak afternoon hours,
  • wearing light cotton clothes,
  • using masks in polluted areas,
  • maintaining proper indoor ventilation.
The expert recommended people to also avoid strenuous outdoor activities during high pollution or heatwave alerts. Creating awareness and taking timely precautions is essential to protect public health from the growing impact of climate and environmental changes.

Weather Today

Residents in Delhi continue to struggle against soaring temperatures and blazing sunshine. The India Meteorological Department (IMD) has issued a yellow alert for the next three days, warning of continued heatwave conditions along with strong surface winds during the afternoons and evenings.

The maximum temperatures are expected to increase by a further 1°C-2°C within the next 24 hours and are forecast to stay high until May 27.

The national capital recorded a maximum temperature of 43.6 degrees Celsius on Sunday, around 3.4 degrees above the seasonal average. The minimum temperature settled at 28.4 degrees Celsius in the morning, nearly two degrees above normal.

Last week, the Commission for Air Quality Management (CAQM) invoked Stage 1 of the Graded Response Action Plan (GRAP) across Delhi-NCR after the city’s air quality slipped into the ‘poor’ category.

Ebola Cases Cross 900, Death Toll Tops 200; 10 Countries On High Alert

Updated May 25, 2026 | 01:04 PM IST

SummaryAccording to experts, high mobility and insecurity in Congo and Uganda, coupled with the ongoing violence against healthcare workers, are fueling the spread of the disease.

Cases of the highly infectious and deadly Ebola virus have crossed over 900 in the Democratic Republic of Congo and Uganda, the World Health Organization said.

The outbreak has been identified as caused by the rare Bundibugyo strain, which differs from other known ebolaviruses, such as Zaire ebolavirus and Sudan ebolavirus. It also has no treatment or vaccine.

The death toll due to the disease has also reportedly surged over 200.

"As surveillance efforts have been scaled up in the #DRC #Ebola response, more than 900 suspected cases have been identified so far, including 101 confirmed cases,” Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization (WHO), shared in a post on social media platform X.

"In Ituri province, the epicenter of the outbreak, nearly 5 million people live amid ongoing conflict. Today, 1 in 4 people are in need of humanitarian assistance, and 1 in 5 are internally displaced," he added.

Ebola Outbreak: 10 countries at risk

The ongoing Ebola outbreak is the 17th outbreak of Ebola virus in the Democratic Republic of the Congo. It is also the third recorded due to the rare Bundibugyo strain.

The outbreak, which has also spread to Uganda, has been declared a Public Health Emergency of International Concern (PHEIC) by the WHO.

According to the African Union's health agency, more countries on the continent are at risk of being affected by the Ebola virus.

"We have 10 countries at risk," said Jean Kaseya, head of the Africa Centres for Disease Control and Prevention (Africa CDC), listing the following:

  • Angola
  • Burundi
  • Central African Republic
  • Republic of Congo
  • Ethiopia
  • Kenya
  • Rwanda
  • South Sudan
  • Tanzania
  • Zambia.
Kaseya noted that "high mobility and insecurity" in the region were helping spread the disease.

Another reason for the spread is the ongoing violence against healthcare workers.

The WHO chief has also voiced out concerns of violence in affected countries that is "forcing people to flee, including health and humanitarian workers".

Last week, the Rwampara health centre was stormed by a group of angry residents demanding the bodies of relatives who had died from Ebola, according to local sources. A day later, a tent provided by Doctors Without Borders, also known by its acronym MSF, at a hospital in Mongbwalu in Ituri province was set on fire.

The adverse conditions has also displaced people, further increasing the transmission of the virus in crowded relief camps.

Tedros noted that "this is severely impeding efforts to scale up Ebola contact tracing and identify infections early enough to provide supportive care. Ongoing insecurity and fear are also fueling mistrust within communities".

What Is Ebola?

Ebola is a severe and, in most cases, deadly disease caused by viruses predominantly found in Africa. The spread of the disease happens through contact with infected body fluids.

Some symptoms can indicate a possible infection. This includes fever, weakness, headache, muscle pain, vomiting, diarrhea, sore throat, and unexplained bleeding. This eventually leads to severe complications like bleeding, organ failure, and death. The hosts of the virus are animals like bats, primates, and antelopes.

WHO Says Vaccine Could Take Months

Meanwhile, the WHO says it could take up to nine months before a vaccine against this particular species of Ebola is ready.

Two possible "candidate vaccines" against the Bundibugyo species are being developed, but neither has gone through clinical trials yet, WHO advisor Dr. Vasee Moorthy said, according to the BBC.

Dubai Paramedics Revive Man After Heart Attack Using CPR Machine: What Is CPR And How Does It Save Lives?

Updated May 23, 2026 | 02:04 PM IST

SummaryCPR, or Cardiopulmonary Resuscitation, is an emergency life-saving technique used when a person stops breathing or their heart stops beating. Quick action is critical, as CPR can double or even triple a person’s chances of survival.

In a remarkable emergency response, Dubai paramedics revived a man who collapsed from a heart attack, earning widespread praise on social media.

The man reportedly collapsed suddenly and showed no signs of consciousness or a pulse. People at the scene immediately alerted emergency services, who responded within minutes. The team began cardiopulmonary resuscitation (CPR) using an advanced CPR machine.

A video now going viral on social media shows paramedics arriving within minutes and performing CPR using the LUCAS 3 automatic chest compression device. The machine, which delivers high-quality chest compressions more consistently than manual CPR, helped circulate blood to vital organs and revived the man within minutes.

“Dubai’s emergency response looks like the future: a man collapses from a heart attack, paramedics arrive within minutes, strap on the LUCAS 3 automatic CPR device, and revive him right there,” a social media user wrote.

“If there were a machine like this, it would be a huge help because people wouldn’t have to perform CPR for a long time,” another user added.

How The LUCAS 3 Device Saves Lives

The LUCAS 3 chest compression system is a mechanical CPR device originally developed by Swedish startup Jolife AB in collaboration with Norwegian inventor Willy Vistung and cardiologist Stig Steen. The device and company were later acquired by medical technology company Stryker in 2016.

The device is designed to deliver continuous, high-quality chest compressions while reducing physical strain on caregivers.

According to the company, studies have shown that the LUCAS device can improve blood flow to the brain and achieve higher EtCO2 values compared to manual chest compressions. With more than 50,000 devices in use worldwide, including within the Dubai Corporation for Ambulance Services, a patient is reportedly treated using the device approximately every minute, it added.

What Is CPR? How To Give CPR?

CPR, or Cardiopulmonary Resuscitation, is an emergency life-saving technique used when a person stops breathing or their heart stops beating. Quick action is critical, as CPR can double or even triple a person’s chances of survival.

Steps to keep in Mind While Giving CPR

Step 1: Check The Surroundings

Ensure the area is safe by checking for dangers such as traffic, fire, or falling objects.

Step 2: Position The Person

Lay the person on their back on a firm surface and open the airway by tilting the head back slightly. Check the mouth for any visible obstruction and remove it carefully if possible.

Step 3: Check Breathing

Listen for breathing sounds for no more than 10 seconds. If the person is not breathing normally, begin CPR immediately.

Step 4: Chest Compressions

Place the heel of one hand at the center of the chest, slightly below the nipple line. Place your other hand on top and interlock your fingers. Keep your elbows straight and push hard and fast — about 2 inches deep — at a rate of 100 to 120 compressions per minute. Allow the chest to rise fully between compressions.

Step 5: Rescue Breaths

After 30 compressions, tilt the person’s head back, lift the chin, pinch the nose shut, and seal your mouth over theirs. Give two rescue breaths, each lasting about one second, while watching for chest rise. If the chest does not rise, reposition the head and try again.

Step 6: Repeat The Cycle

Continue alternating 30 chest compressions with 2 rescue breaths until the person starts breathing or emergency medical professionals arrive.

Key Considerations For CPR

  • CPR should be used in emergencies such as cardiac arrest, drowning, choking, or severe trauma.
  • Always confirm that the person is unresponsive and not breathing normally before starting CPR.
  • CPR is intended for emergency situations. If a healthcare professional is nearby, seek their assistance immediately.
Note: This is only for emergency circumstance. If there is a healthcare or a medical professional next to you, it is always advisable to seek for their help.
