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.

Takeda Biopharmaceuticals India today announced that QDENGA (TAK-003) has become the first dengue vaccine to receive approval in India, marking a major milestone in the country's fight against the mosquito-borne disease.
The Drug Controller General of India (DCGI) has granted market authorization for QDENGA to prevent dengue in individuals aged 4-60 years. According to Takeda, it is India's first approved dengue vaccine and can be administered regardless of previous dengue infection, without requiring pre-vaccination testing.
"Since its launch in 2022, QDENGA has been approved in 43 countries, with more than 32 million doses distributed globally. This approval marks an important step forward in strengthening dengue prevention in India," said Dr. Mahender Nayak, Head of Intercontinental Markets.
The approval comes at a critical time as dengue cases in India have risen sharply over the past two decades.
India accounts for nearly one-third of the global dengue burden. In 2025, more than 113,000 dengue cases were officially reported, although modelling studies suggest the true number of infections may run into tens of millions annually due to underreporting.
Rapid urbanization, climate change and widespread mosquito breeding have made dengue a year-round public health concern. Since there is no specific antiviral treatment for dengue, prevention remains the most effective strategy.
"India carries a substantial dengue burden, and all four dengue virus serotypes co-circulate in several regions. QDENGA is designed to protect against all four serotypes regardless of prior exposure," said Dr. Goh Choo Beng, Medical Affairs Head, Southeast Asia & India Cluster.
The DCGI approval is supported by Takeda's global clinical development programme comprising 19 Phase 1, 2 and 3 clinical trials involving more than 28,000 participants in dengue-endemic and non-endemic regions.
The pivotal Phase III TIDES (DEN-301) study enrolled more than 20,000 participants across eight countries and evaluated the vaccine's long-term safety and effectiveness.
Key findings include:
The approval is also supported by an Indian Phase III (DEN-302) trial involving participants aged 4-60 years, which found QDENGA to be safe, well-tolerated and immunogenic in children, adolescents and adults.

QDENGA (TAK-003) is a live-attenuated tetravalent dengue vaccine designed to protect against all four dengue virus serotypes.
It is administered as two 0.5 mL subcutaneous doses, given three months apart.
The vaccine is built on a DENV-2 backbone, incorporating structural proteins from DENV-1, DENV-3 and DENV-4 to provide broad immune protection.
The World Health Organization (WHO) recommends QDENGA for use in dengue-endemic settings without the need for pre-vaccination screening. The vaccine is also included in the WHO List of Prequalified Vaccines, allowing procurement through agencies such as UNICEF and PAHO.
The vaccine has been approved in 43 countries across Asia, Latin America and Europe. It is already part of Brazil's National Immunization Program and is available through public immunization programmes in Argentina, Colombia and Indonesia.
The vaccine is approved in India for people aged 4-60 years to help prevent dengue disease.
Takeda had partnered with Indian vaccine manufacturer Biological E in 2024 to expand production of QDENGA.
Under the agreement, Biological E plans to manufacture 50 million doses annually, supporting Takeda's goal of producing 100 million doses globally each year by the end of the decade.

A minimally invasive treatment that targets only cancerous tissue in the prostate may offer the same chance of treating localized prostate cancer as surgery or radiotherapy while causing significantly fewer side effects, according to a major UK study.
The findings suggest that focal therapy, which destroys only the tumor while preserving the healthy parts of the prostate, could become a viable treatment option for carefully selected patients.
It could help reduce common risks like urinary incontinence and erectile dysfunction that follow conventional treatment.
The study, presented by University College London (UCL) and collaborating institutions, compared long-term outcomes of men treated with focal therapy against those receiving radical prostatectomy or radiotherapy.
Researchers found that cancer control was comparable across the treatment groups, while men undergoing focal therapy experienced substantially better functional outcomes.
"This study shows that men with localized prostate cancer do not necessarily have to choose between effective cancer treatment and preserving their quality of life," said Professor Caroline Moore, Professor of Urology at University College London.
"Our results demonstrate that focal therapy can control cancer effectively in appropriately selected men while significantly reducing the side effects associated with whole-gland treatments."
Unlike surgery, which removes the entire prostate, or radiotherapy, which treats the whole gland, focal therapy targets only the cancer with the help of high-intensity focused ultrasound (HIFU). By sparing healthy tissue and surrounding nerves, the treatment aims to preserve urinary and sexual function.
According to the researchers, the study provides strong evidence that focal therapy can offer outcomes similar to standard treatments in men whose cancer is confined to a specific area of the prostate.
Professor Moore cautioned that focal therapy for prostate cancer may not be suitable for every patient. "It is important that men undergo careful assessment with high-quality imaging and biopsy so that we can identify those who are most likely to benefit from this treatment," she said.
The researchers also emphasized that patients receiving focal therapy require ongoing follow-up, including prostate-specific antigen (PSA) testing and imaging, to monitor any recurrence or progression of disease.

The findings have drawn renewed public attention after television presenter Jeremy Clarkson recently disclosed that he underwent treatment for prostate cancer.
Clarkson revealed that he chose a treatment that reduced long-term side effects, raising awareness about prostate cancer, and the importance of early diagnosis.
Prostate cancer is among the most commonly diagnosed cancers in men worldwide. While surgery and radiotherapy remain the standard treatments for localized disease, both can result in complications like urinary leakage, bowel problems and erectile dysfunction that can affect the quality of life.
Experts say the new findings support a growing shift toward more personalized treatment strategies that balance cancer treatment with quality of life.

COVID-19 is seeing a renewed uptick in India, with 339 infections reported between July 1 and July 16, according to the Andhra Pradesh Health Department.
Andhra Pradesh has reported four COVID-related deaths and 19 active cases, prompting heightened surveillance after officials identified the Omicron RF.5 sublineage in infected patients in the state.
The presence of RF.5 sublineage in Andhra was confirmed through genome sequencing of patient samples from YSR Kadapa district at the National Institute of Virology (NIV), Pune.
According to the Andhra Pradesh Health Department states that reported COVID infections fromJuly 1-16 include:
RF.5 is an Omicron sublineage identified through genome sequencing. The World Health Organization (WHO) is monitoring the variant after it was reported in higher numbers in Singapore and other parts of Southeast Asia, prompting Indian health authorities to closely track its spread.
According to the Andhra Pradesh government, RF.5 evolved naturally from the Omicron JN.1 lineage through the LF.7 and PY.1.1.1 sublineages.
Officials said it is not a recombinant variant, meaning it evolved within a single genetic lineage rather than through the combination of two different variants.
Based on current evidence, Dr. Vishnuvardhan said there is no indication that RF.5 causes more severe disease than other Omicron subvariants currently in circulation, although continued surveillance remains important.
The symptoms of RF.5 are similar to those seen with other Omicron variants and include:
In a post on X, Dr. Vipin M. Vashishtha, Member of the WHO Vaccine Safety Net (VSN), said RF.5 carries several spike mutations that may influence how the virus behaves:
However, Dr. Vashishtha said these mutations alone should not be considered reliable predictors of disease severity. RF.5 continues to be monitored through WHO genomic surveillance.
According to health officials, there is currently no cause for alarm.
