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.

Jenny Simpson Reveals Rare Heart Condition That Makes Running Dangerous

Updated Aug 21, 2026 | 12:02 AM IST

SummaryIn Arrhythmogenic ‌Right Ventricular Cardiomyopathy (ARVC), heart muscle cells do not stick together properly, causing scar tissue and weakening the heart muscle. This can affect the heart’s ability to pump blood effectively.
Jenny Simpson Reveals Rare Heart Condition That Makes Running Dangerous

American Olympic bronze medallist Jenny Simpson has announced her diagnosis of Arrhythmogenic ‌Right Ventricular Cardiomyopathy (ARVC) -- a rare inherited heart condition that is forcing her to give up her career as it makes running dangerous.

The 39-year-old, former 1500 meters world champion, was diagnosed after collapsing in June ⁠at a community track event hosted by Sir Walter Running and required CPR.

What Happened To Jenny Simpson?

After receiving lifesaving care at the track event, Simpson was transferred to Duke University Hospital for more advanced heart failure support.

Her heart was not pumping strongly enough, causing fluid to build up in her lungs. She described the experience as beginning to “drown.”

“My body was dying, but my spirit wouldn’t give up,” her post read. “I fought for my life.”

Within days, however, her heart and lungs were strong enough to function on their own.

Simpson Forced To End Her Career

Simpson said her diagnosis means “it would be dangerous for me to return to running.” She retired from elite racing in 2024 and described the diagnosis as the end of that chapter of her life.

"I was diagnosed with a rare inherited heart condition, Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)... My future is an incredible gift. It is hopeful, and it will continue to have a ‌great ⁠purpose. But my diagnosis also means it would be dangerous for me to return to running," Simpson said in a post on Instagram.

“That chapter has ended,” the post read. “Thankfully, my story hasn’t.”

Why Can ARVC Be Dangerous?

Simpson was diagnosed with ARVC, a rare inherited condition in which scar tissue in the heart can disrupt its electrical system and trigger dangerous heart rhythms.

The condition can weaken the heart muscle and affect its ability to pump blood effectively. It can affect one or both ventricles; when it mainly affects the right ventricle, it is called ARVC. In Simpson’s case, the abnormal heart rhythms ultimately caused her heart to stop.

“As devastating as that diagnosis sounds, I truly feel profoundly fortunate. CPR, AED shocks, exceptional medical care, and a healthy body and fighting spirit that have spent a lifetime adapting to hard things all came together to give me another chance at life.”

Simpson is the only US woman to win a world 1500m title, which she achieved in 2011, and one of two US women to win an Olympic 1500m medal, taking bronze in 2016.

From 2007 through 2019, she finished among the top three in the 1500m, 5000m or 3000m steeplechase at all 13 USA Track and Field Outdoor Championships.

What Is ARVC?

In ARVC, heart muscle cells do not stick together properly, causing scar tissue and weakening the heart muscle. This can affect the heart’s ability to pump blood effectively.

The condition can affect one or both ventricles. When it primarily affects the right ventricle, it is called ARVC.

ARVC: Symptoms

Some people may have no symptoms. Others may experience:

  • Heart palpitations
  • Lightheadedness
  • Fainting
  • Shortness of breath
  • Abnormal heart rhythms
  • Swelling in the ankles, legs or abdomen
  • Chest pain or discomfort
Symptoms may become more noticeable as the condition progresses.

ARVC: Diagnosis

Doctors may use several tests to assess the heart, including:

  • Cardiac MRI
  • ECG
  • Exercise test
  • Echocardiogram

ARVC: Treatment

There is no cure for ARVC, but treatment can help manage abnormal heart rhythms and reduce complications. Options may include:

  • Pacemaker
  • ICD
  • Cardioversion
  • Catheter ablation.

Microplastics Found In Anchovies’ Edible Muscle: What It Means For Brain Health

Updated Aug 20, 2026 | 10:20 PM IST

SummaryMicroplastic particles were found in the gastrointestinal tracts, gills and muscle tissue of fish collected from Visakhapatnam’s Vizag harbor. The GI had the highest concentration, followed by the gills and muscle tissue
Microplastics Found In Anchovies’ Edible Muscle: What It Means For Brain Health

Anchovies are tiny fish packed with major health benefits, including high amounts of heart-healthy omega-3 fatty acids (EPA and DHA), lean protein, selenium, niacin, iron and calcium. However, a new study by Andhra University researchers detected microplastics in the edible muscle tissue of anchovies, which form a significant part of the local seafood chain.

The finding, published in the International Journal of Environmental Sciences, raises concerns about potential exposure to microplastics and their possible impact on cognitive function.

While the detection of microplastics in muscle tissue suggests the particles may move beyond the digestive system and potentially expose humans through contaminated seafood, researchers led by Prof C Manjulatha from the Department of Zoology and Gondu Chandrika from the Department of Environmental Sciences stressed the need for further assessment.

Where Were Microplastics Found?

  • Microplastic particles were found in the gastrointestinal tracts, gills and muscle tissue of fish collected from Visakhapatnam’s Vizag harbor.
  • The gastrointestinal tract had the highest concentration, followed by the gills and muscle tissue, according to Times of India.
  • Plastic fibers accounted for nearly 80% of the detected particles, followed by fragments and foam.
  • Most particles measured between 0.5 mm and 4.5 mm.
  • The researchers identified particles in different colors, with red and blue among the prominent ones.
  • FTIR spectroscopy identified polymers including polyamide, PET, polyester, polyethylene, polyacrylate and polypropylene.

Polyamide and PET were among the dominant polymers, pointing to multiple possible sources of contamination, such as synthetic fibers, plastic waste and fishing-related materials.

“These findings emphasize the need for proper disposal and treatment of plastic waste,” the researchers said.

What Does This Mean For Brain Health?

Microplastics are small pieces of plastic, ranging from one nanometer to five millimeters — a fraction of the width of a human hair to about the size of a grain of rice. These have now been detected in human blood, placenta, liver, kidneys and the brain. The study also prompted questions about whether consuming microplastics could have implications for brain health.

In a post on X, Dr Sudhir Kumar, Neurologist at Apollo Hospitals, Hyderabad, explained that although the gastrointestinal tract had the highest load, muscle contamination is what reaches your plate.

“Microplastics tend to accumulate in fat-rich tissue like the brain's myelin sheath, the insulation around neurons. Animal studies show microplastic exposure can trigger oxidative stress and inflammation that disrupt neurotransmission and impair cognition. Human data is still emerging, but the biological plausibility is real,” Dr Sudhir said.

He stressed that it “is a concerning signal, not yet a confirmed verdict”.

Can Microplastics End Up On Our Plates?

“Plastic pollution entering the sea fragments into particles small enough for marine life to absorb; fish take it up through feeding, we take it up by eating the fish. The Vizag study flags exactly this: sewage discharge, urban runoff, and fishing waste feeding this cycle,” the expert said.

How To Stay Safe

The expert advised people to:

  • Vary protein sources.
  • Don't rely on one fish species or source daily.
  • Reduce synthetic fibre shedding and use a laundry filter bag.
  • Avoid heating food in plastic containers.
  • Support better waste treatment, as it is fundamentally a pollution problem, not just a diet one.

Measles Outbreak In Sweden: 21 Confirmed Cases Linked To Music Festival

Updated Aug 20, 2026 | 09:20 PM IST

SummarySweden’s childhood vaccination programme includes the measles vaccine and has 95 percent coverage. As per an expert, the high vaccination rate means, Sweden may not currently be at risk of a major outbreak in the wider population.

The number of measles cases in Sweden linked to the Urkult Festival has climbed to 21, according to the latest data from the country’s Public Health Agency.

So far, all known cases have been directly linked to the festival, which took place from July 30 to August 2 in Näsåker, in Sollefteå municipality. The majority of those infected are children under 18 years of age, the report said.

Acting State Epidemiologist Erik Sturegård called the rapidly growing number of cases “very unusual” in Sweden, Sweden Herald reported. “It is a disease that can cause very serious illness, even in otherwise healthy children,” Sturegård said.

Sweden’s childhood vaccination program includes the measles vaccine and has 95 percent coverage.

Sturegård said the high vaccination rate means Sweden may not currently be at risk of a major outbreak in the wider population.

However, unvaccinated people, as well as those with underlying conditions that may prevent the vaccine from providing adequate protection, remain at risk of serious illness.

Sturegård noted that most of those infected had not been vaccinated against measles.

“Even though we have 95 percent vaccination coverage in the childhood vaccination program, we have small pockets of people who, for various reasons, have not been reached by the vaccination, or who have chosen not to vaccinate themselves. Then you get a local minor outbreak very easily when measles is so extremely contagious,” Sturegård said.

Regions Reporting Measles Cases

The cases have been reported from the following regions:

  • Jämtland Härjedalen
  • Skåne
  • Stockholm
  • Västerbotten
  • Gotland
  • Värmland
  • Västernorrland

Measles is highly contagious, making contact tracing time-critical. The Public Health Agency, which has overall responsibility for infectious disease control in Sweden, is in daily contact with the affected regions.

“We have daily meetings with the relevant infection control departments to keep a full overview of what is happening and be able to provide the support needed,” Sturegård said.

Measles Symptoms

Measles is an extremely contagious viral illness that spreads through respiratory droplets when an infected person coughs or sneezes. It can also spread through contact with contaminated surfaces.

The illness typically causes high fever, cough, runny nose, red and watery eyes and a characteristic rash that usually begins on the face and spreads downward across the body.

Other symptoms can include sneezing and small white spots inside the mouth. Measles can cause serious and sometimes fatal complications, including pneumonia and encephalitis, or inflammation of the brain.

Measles Cases Reported Across Europe

According to the European Centre for Disease Prevention and Control’s latest July 2026 report, nine European countries reported 188 measles cases in June. The highest number of cases was reported by:

  • Bulgaria: 102
  • Italy: 41
  • Belgium: 14
  • Spain: 13

In the 12 months through June 30, 2026, 30 EU/EEA Member States reported a total of 2,472 measles cases.

Of these, 717 cases (29.0%) were among children under five years of age, while 1,261 (51.0%) were among people aged 15 years and older.

The highest notification rates were recorded among infants under one year of age, at 62.9 cases per million, followed by children aged 1–4 years, at 30.8 cases per million.

Among cases with known age and vaccination status, 1,602 (74.0%) were unvaccinated, 323 (14.9%) had received one dose of a measles-containing vaccine, and 198 (9.1%) had received two or more doses. Another 41 cases (1.9%) had an unknown number of vaccine doses.
