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.
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.
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.

Amid a record-high measles outbreak in the US, Pennsylvania has reported the first measles deaths of 2026, involving two unvaccinated individuals.
According to a statement by the Pennsylvania Department of Health (DOH), the confirmed deaths “mark the first deaths related to measles within the Commonwealth in 35 years.”
Both people were unvaccinated residents of Lancaster County, according to the DOH, which did not release additional details, citing privacy concerns.
“Because measles was largely eliminated in the Commonwealth for more than three decades, people are not familiar with this disease and don't fully understand the potential severity of the illness,” said Pennsylvania Secretary of Health Debra Bogen.
Pennsylvania has been one of the hardest-hit states this year. So far, 393 cases of the contagious virus has been reported across 28 counties. Lancaster County, in the southeastern part of the state, has recorded 185 cases.
The best protection against measles is getting fully vaccinated. The MMR vaccine, administered over two doses, boosts a person’s immune system and provides 97% lifetime protection.
However, vaccination rates and policies under the President Donald Trump, along with long-term vaccine skeptic Health Secretary Robert F. Kennedy Jr., have led to a severe decline in immunization rates.
As per the latest figures from the US CDC, the country has recorded 2,777 confirmed measles cases this year, a disease that had been largely eradicated in the country.
Notably, the increase in cases also means that the US is set to lose its status for having eradicated measles.
Moreover, Kennedy and President Donald Trump, earlier this month, issued an executive order calling for a reduction in recommended childhood vaccines and also promoted a long-debunked link between vaccines and autism, contrary to established scientific evidence.
“We all thought the Texas outbreak and the deaths there last year would be a wake-up call. Then we had the outbreaks in South Carolina and Utah,” said Dr. Angela Dunn, former Utah state epidemiologist and previously a CDC division director in infectious disease response, Reuters reported.
In 2025, three people died in an outbreak that began in West Texas and spread to New Mexico.
Measles is a highly contagious virus that can cause serious short- and long-term health problems, including pneumonia and brain swelling. Nearly 20% of people who contract measles are hospitalized. Death related to measles, though rare, occurs in one to three patients per 1,000 cases.
Measles spreads when an infected person breathes, coughs, or sneezes. The virus remains infectious in the air and on surfaces for up to two hours after the person with the infection leaves the area.
Early symptoms of measles include fever, cough, runny nose, and red, watery eyes (conjunctivitis). The measles rash follows a few days later, starting on the head and spreading downward.
Because early symptoms can look similar to other respiratory viral infections, it is important to contact a healthcare provider early if someone has these symptoms or may have been exposed to measles.
Symptoms can start 7 to 21 days after exposure. Without proper protection or supportive care, measles can be deadly.

Even as Delhi’s H1N1 cases crossed 2,300, Director General of the Indian Council of Medical Research (ICMR) Dr. Rajiv Bahl today said there was “absolutely no cause for panic” and that seasonal influenza remains largely self-limiting.
Speaking to the media, Dr. Bahl said no new or unusual virus strain has been detected and that the rise in cases reflects expected seasonal changes.
The virus currently circulating in the country is the familiar H1N1 pdm09 strain that emerged during the 2009 pandemic and has since become a seasonal influenza virus.
The circulating Influenza A (H1N1) viruses have been identified as A/Missouri/11/2025 (H1N1) pdm09-like viruses. Hemagglutinin (HA) gene analysis places the isolates in clade 6B.1A.5a2a, subclade D.3.1.1.
Dr. Bahl said this lineage has been in continuous circulation in India since 2025. The genetic changes observed are consistent with the normal antigenic drift seen in seasonal influenza viruses.
Such minor genetic changes occur routinely as influenza viruses circulate and, by themselves, do not indicate the emergence of a new or dangerous strain.
Dr. Bahl, who is also Secretary of the Department of Health Research (DHR), said there is no urgent need for everyone to take the flu vaccine.
He added that individuals above 65 and those who are immunocompromised may discuss vaccination with their doctors. He said that vaccination is currently only a recommendation from the WHO and is not part of the National Immunization Program.
Seasonal influenza, including Influenza A (H1N1), is predominantly a mild and self-limiting respiratory illness in otherwise healthy individuals.
Common symptoms include:
In most people, symptoms improve with supportive care, adequate rest and hydration. The presence of H1N1 does not, by itself, mean that a person will develop severe disease or require hospitalization.
However, certain groups have a higher risk of developing complications. These include:
Dr. Bahl advised these individuals to exercise greater caution and seek timely medical advice if they develop influenza-like symptoms.
Dr. Bahl advised the public to follow routine respiratory hygiene and infection-prevention measures.
Do's:
Don’t:
The Ministry of Health said the public should remain “informed and vigilant, but not alarmed.”
Seasonal influenza is a familiar and routinely monitored respiratory infection. Following simple preventive measures, seeking timely medical consultation when required and avoiding unnecessary medication can help protect individuals and communities.

A massive analysis involving more than 100 million people has found strong links between recreational drug use and stroke, including among younger adults.
Stroke remains one of the world's biggest health problems and ranks as the third leading cause of death and disability combined.
The researchers found that cannabis use disorders were associated with stroke overall and were particularly linked to large artery stroke.
The study "provides compelling evidence that drugs like cocaine, amphetamines, and cannabis are causal risk factors for stroke. These findings give us stronger evidence to guide future research and public health strategies," said Dr. Megan Ritson from the Stroke Research Group at the University of Cambridge.
The team conducted a meta-analysis covering studies with more than 100 million participants. Their results, published in the International Journal of Stroke, showed substantial differences in stroke risk associated with several drugs.
Cocaine and amphetamine use were each linked to roughly twice the risk of stroke.
The researchers separately examined people under age 55. Within this younger group, amphetamine use was associated with nearly three times the risk of stroke, an increase of 174%.
Cocaine use was associated with a 97% increase in stroke risk, while cannabis was linked to a smaller 14% increase.
Further genetic analysis revealed that cocaine use disorders were especially associated with brain hemorrhage and cardioembolic stroke.
In cardioembolic stroke, a blood clot forms in the heart and travels to the brain, blocking blood flow and causing damage to brain tissue.
According to the researchers, these genetic findings support the possibility of a causal relationship rather than an association alone.
Problematic alcohol use was also associated with an increased risk of cardioembolic stroke and large artery stroke. Alcohol addiction, meanwhile, was linked to a greater overall risk of stroke.
The researchers noted several biological mechanisms that could help explain why these substances are associated with stroke. These include:
All of these processes are already known to contribute to stroke. They can play a role in ischemic strokes, which occur when blood clots interrupt blood flow, as well as hemorrhagic strokes.
"Our analysis suggests that it is these drugs themselves that increase the risk of stroke, not just other lifestyle factors among users. Taken together, our findings emphasize the importance of public health measures to reduce substance abuse as a way of helping also reduce stroke risk," said Dr. Eric Harshfield, Alzheimer's Society Research Fellow at the Department of Clinical Neurosciences.
