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.

Three cases of meningitis have been reported among schoolchildren in the Weymouth area in the UK, health officials said.
According to the UK Health Security Agency (UKHSA), of the three cases, two are pupils at Budmouth Academy, Weymouth, and the third attends Wey Valley Academy. The authorities have now rolled out meningitis vaccinations to young people in the region.
The latest outbreak comes after a meningitis outbreak was reported in the Kent region in March, which affected more than 30 people, leaving one sixth-form pupil and a university student dead.
As per the UKHSA, the new cases were confirmed between 20 March and 15 April and are not linked to the deadly Kent outbreak.
The two pupils at Budmouth Academy are contacts of each other, but it is reportedly not epidemiologically linked with the Wey Valley Academy case.
The three cases in Weymouth have been confirmed as Meningitis B (MenB) and are the same sub-strain type, but a different sub-strain to the one detected recently in Kent.
Notably, all pupils in years 7 to 13 in Weymouth, Portland, and Chickerell are to be offered antibiotics and the MenB vaccination.
Close contacts of the cases have already been offered antibiotics as a precaution.

According to UKHSA deputy director Dr Beth Smout, "it is possible that we will see further cases linked to these latest cases in Weymouth".
He stated that the authorities are widening the "offer of antibiotics and vaccination" as "an additional precaution" to reduce the risk of the infection spreading.
"School pupils and staff should attend school as normal if they remain well," the official said.
Meningitis is a serious medical condition that affects the protective membranes covering the brain and spinal cord, the meninges. While fever is not always present, it is usually considered one of the classic symptoms of meningitis.
It is important to know the varied symptoms, causes, and treatments of meningitis for early diagnosis and proper management of the disease.

Smout urged everyone to be alert to the signs and symptoms of meningococcal meningitis. Common symptoms of meningitis
"If the disease is suspected, you should seek immediate medical attention as the disease can progress rapidly," Smout said.
"The most important short-term thing and the quickest way for people to protect themselves is the antibiotic.
"The vaccine offers longer-term protection. There are two doses, four to six weeks apart, and you are only protected after the second dose," the official said.
A 2026 target trial emulation has found that glucagon-like peptide, also known as GLP-1, which is used by type-2 diabetes patients, can raise the risk of suffering from erectile dysfunction. According to a report published in the European Medical Journal, the impact of GLP-1s on sexual health outcomes in diabetic men has been inconsistent and limited. Erectile dysfunction, however, has been a prominent complication affecting 50 per cent of men with type-2 diabetes over their lifetime.
For this, researchers analysed the electronic health records of men aged 18 years and above with type-2 diabetes in the US from January 2019 to September 2024. Participants were started on treatment with either dipeptidyl peptidase-4 inhibitors (DPP4i) or GLP-1, with 5,524 and 4,910 individuals, respectively. Men with a history of erectile dysfunction diagnosis or end-stage renal disease were not part of the study population. The mean age of these men was 63 years, and the average BMI was 32.8—55 per cent of participants were White, and 23 per cent were Black. GLP-1 users were younger and had a higher prevalence of obesity compared to DPP4i users.
Experts involved in the study found that the incidence of erectile dysfunction in the GLP-1 group was about 35 cases per 1,000 person-years. In the case of DPP4i users, the number dropped to 28 per 1,000 person-years. Hence, people in the GLP-1 cohort had a 26 per cent higher risk of developing erectile dysfunction over a three-year follow-up period. Results were consistent across subgroups; however, they lacked statistical significance after adjustment for negative outcomes.
Researchers noted that the findings of the target trial emulation suggest that sexual health outcomes must be considered in diabetic men, especially those dealing with type-2 diabetes and undergoing treatment with GLP-1 drugs. These findings also highlight the need for randomised trials with standardised erectile dysfunction assessments to further investigate biological pathways.
Type-2 diabetes can cause the following complications in men:
Modern guidelines recommend women undergo breast cancer risk assessment at 35 years itself. (Photo credit: iStock)
New global guidelines have just been released for breast cancer screening, and they involve the introduction of artificial intelligence in the process. Breast cancer is one of the most commonly diagnosed forms of tumour in women globally. In India, it is the most common form of cancer detected in women living in metro cities. According to the National Comprehensive Cancer Network (NCCN), a non-profit alliance of 33 cancer treatment centres in the US, women aged 35 years and above should be eligible for AI-powered mammogram risk assessment rather than at a later stage.
The NCCN aims to boost the diagnosis rates of breast cancer by paving the way for accurate predictions of risks. This will, over time, help achieve timely screening. As per experts, this change in global breast cancer screening guidelines, especially the integration of AI in the process, marks a paradigm shift—from a detection-first to a prediction-first approach. Historically, mammograms were used after the age of 40 for the detection of existing cancers. The modern guidelines, however, recommend that women get screened from the age of 35 onwards, with AI algorithms used to predict future risks.
Experts say that this shift is important for India. In India, breast cancer is the most prevalent form of tumour among women, and delayed diagnosis is one of the reasons responsible for the current mortality rate. Breast cancer is also often diagnosed late because of the unavailability and limited accessibility of screening facilities. Introducing AI in this process can help bridge the gap in several ways.
Doctors say that the introduction of AI in the breast cancer screening process will help facilitate the identification of high-risk patients, regardless of their family history or the presence of genetic markers. This is important because most cases of breast cancer do not arise from these factors. This helps provide screening in a way that does not require universal testing.
Traditionally, cancer screening largely depends on family history and age. AI, however, can now analyse large volumes of imaging data, clinical history, breast density, and genetic factors for a more personalised approach and targeted diagnostic methods. The adoption of AI-driven risk assessment can help improve patient outcomes, as per doctors.
Women at high risk of breast cancer can make detection easier for themselves by making use of advanced modalities such as MRI. An MIT-developed AI-based breast cancer risk model can detect tumours up to five years in advance using mammographic data alone. This AI-based risk assessment technique has also been recommended by global experts and is published in The Lancet. The study found consistent favourable outcomes.
