Blockbuster weight loss jabs ‘significantly lower' the risk of dementia
Researchers found that semaglutide - the active ingredient in Ozempic and Wegovy - could "significantly" slash the risk of the brain-robbing disease in people with type 2 diabetes.
Study leader Professor Rong Xu said: "There is no cure or effective treatment for dementia, so this new study provides real-world evidence for its potential impact on preventing or slowing dementia development among a high risk population."
Semaglutide, part of a group of drugs called GLP-1 agonists, was originally invented to treat type 2 diabetes.
But trials found it could also cause major weight loss - about 10 to 15 per cent of body weight over 18 months.
It triggers fullness hormones in the gut to prevent hunger and over-eating.
Semaglutide has already been found to lower the risk of heart disease, bowel cancer and fertility issues.
But researchers at Case Western Reserve School of Medicine in Cleveland Ohio, United States, now have evidence it could play a key role in preventing dementia.
The syndrome occurs when brain cells are damaged and their connections stop working properly.
That damage, which worsens over time, impacts memory, thinking and reasoning.
It can be caused by various conditions and events, including obesity diabetes, cardiovascular diseases, traumatic brain injury and stroke.
Previous research has indicated that 45 per cent of dementia cases could be prevented by addressing these " modifiable risk factors".

The new study, published in the Journal of Alzheimer's Disease, analysed the electronic records of nearly 1.7million American patients with type 2 diabetes over three years.
Patients taking semaglutide had a "significantly lower" risk of developing Alzheimer's disease-related dementia compared to those on seven other antidiabetic medications.
This included other types of GLP-1R-targeting drugs.
The results were more "profound" in women and older adults.
Prof Xu said the findings support the idea that semaglutide could prevent dementia.
But she cautioned that more research is needed.
"Our results indicate that research into semaglutide's use for dementia prevention will need to be further investigated through randomised clinical trials," Prof Xu added.
Are you eligible for weight loss jabs on the NHS?
By Sam Blanchard, Health Correspondent
THEY are arguably the biggest medical breakthrough of recent times.
And now, so-called ' fat jabs ' are available to many more Brits on the NHS.
In what marks the dawn of a new era, GPs have begun prescribing the weight loss jab Mounjaro in the first anti- obesity rollout of its kind.
More than three million people are thought to be eligible for tirzepatide - the active drug in Mounjaro - the strongest jab on the market.
Health chiefs hope it will turn the tide on England's obesity crisis which has seen rates double since the 1990s.
Injections including Ozempic and Wegovy have previously only been available for type 2 diabetes or through specialist slimming clinics.
Family doctors will now be encouraged to prescribe them in a bid to get more people on the meds.
Experts hope widespread use will slash work sick days and boost the economy, while reducing rates of cancer, heart disease and dementia.
But demand for the drugs is already huge and NHS clinics cannot dish them out fast enough.
Who is eligible in the new rollout?
The new rollout allows GPs to prescribe tirzepatide for weight loss, starting with those patients whose weight places them at greatest health risk.
Top of the list will be those with a body mass index (BMI) of 40 or higher (or 37.5 if from a minority ethnic background) and four weight-related health conditions.
A BMI of 40 is roughly equal to weighing 16st (102kg) for an average height 5'3' woman, or 19st 6lbs (123kg) for an average 5'9' man.
Weight-related conditions include high cholesterol, high blood pressure, prediabetes, type 2 diabetes, obstructive sleep apnoea and heart disease.
Patients will likely be expected to have tried diet and exercise first before being offered a jab.
Many are likely to miss out, as some 13.5million adults in England are obese but only 3.4million are estimated to be eligible in the rollout.
Professor Kamila Hawthorne, chair of the Royal College of GPs, said: 'Currently only patients who meet certain criteria - those who could benefit most - are eligible to be prescribed weight loss drugs on the NHS, and GPs will also need to follow local guidelines when prescribing.
'If your practice advises you that they won't be able to provide weight loss medication, these will likely be the reasons why.
'We appreciate the idea of weight loss medication is an attractive prospect to many patients - and they do have a lot of potential benefits for patients and may be a valuable tool as we try to tackle obesity at a national level – but it's important these medications aren't seen as a silver bullet.
'Weight loss drugs do not come without risk, they can cause side effects which range in seriousness, and they won't be suitable for everyone.
'It's important we don't lose sight of the role lifestyle factors play in achieving a healthy weight.
'The roll out of weight loss medications as a treatment for obesity must not come at the expense of other weight loss services.'
If you are eligible but your GP denies you a prescription, you may be able to ask for a referral to specialist weight management services.
Known as tier 2 and tier 3 weight management services, they may prescribe the jabs after other weight loss attempts.
Many people are expected to find it easier to go private, with the injections widely available from high street pharmacies like Boots, Superdrug, and even Asda.
There are also numerous online pharmacies offering the drugs.
Buying the drugs online might seem like the faster fix – but buyer beware.
Slimming success stories are everywhere but so, too, are tales of horror.
Many patients have been duped by dodgy sellers, suffered severe side effects or even died after taking jabs they bought online.
Bargain prices, easy tick-box applications, or prescriptions with no follow-up, should all be red flags to online shoppers.

Report: Jerry Jones fought stage 4 cancer battle for over decade
August 13 - By Field Level Media Cowboys owner Jerry Jones revealed that he fought stage 4 melanoma for a decade, the Dallas Morning News reported. Jones was contacted by the newspaper following a comment he made during the Netflix documentary, "America's Team: The Gambler and His Cowboys." In the documentary, Jones referenced undergoing cancer treatments "about a dozen years ago," per the Dallas Morning News. Jones said he underwent treatment at the MD Anderson Cancer Center in Houston in 2010. Jones, now 82, said he had four surgeries over the ensuing decade -- two involving his lungs, two involving his lymph nodes. He credits the experimental trial drug PD-1 (Programmed Cell Death Protein 1) for saving his life. "I was saved by a fabulous treatment and great doctors and a real miracle (drug) called PD-1 (therapy)," Jones said. "I went into trials for that PD-1 and it has been one of the great medicines. I have no tumors." Stage 4 melanoma means "cancer has spread beyond the skin to other organs, such as the lungs or liver," per the Mayo Clinic. According to the Dallas Morning News, the drug helps the immune system "fight cancer cells by blocking PD-1, thus enabling T cells to better recognize and destroy cancer cells."

NASA's nuclear gamble on the moon faces growing skepticism
Fast-tracking a NASA plan to build a nuclear reactor on the moon may sound dubious. Experts say that's because it is. 'The whole proposal is cock-eyed and runs against the sound management of a space program that is now being starved of money,' national security analyst, nuclear expert and author Joseph Cirincione told The Independent. Nuclear has been used in space since the 1960s. That's nothing new. The U.S. launched its first test reactor into orbit in 1965, and the former Soviet Union has sent up dozens more. NASA says that a new 100-kilowatt reactor could be used to power a future base at the lunar South Pole, and fuel prospective missions to Mars and beyond. Nuclear would help to fill gaps in solar energy that occur when that side of the moon is in darkness for two weeks. The majority of space experts have said that placing a reactor on the moon is possible, so, why is NASA's current plan 'cock-eyed?' The problem is the proposed timeline. Interim NASA Administrator Sean Duffy, who also serves as President Donald Trump's Secretary of Transportation, pushed to expedite the project, detailed in a memo this week. Duffy said the administration wanted to have a nuclear reactor ready to launch by 2030. Earlier this year, China and Russia announced a plan to build a nuclear reactor for a lunar base by 2035. 'The first country to do so could potentially declare a 'keep-out' zone which would significantly inhibit the United States from establishing a planned Artemis presence if not there first,' Duffy said. NASA first announced in 2021 that it would put a reactor on the moon 'within a decade.' In 2024, NASA then said that their target date for delivery a reactor to the Earth-based launchpad was the early 2030s. But, Cirincione says essentially no progress has been made. 'It was in the last Trump administration that NASA had put out a press release, they had a YouTube video, they had these announcements about how they're going to develop these small, modular nuclear reactors for use on the moon, and it was going to be ready by 2026,' said Cirincione, who is vice-chair of the Center for International Policy, a non-profit that advocates for a peaceful approach to foreign policy. 'Oh, really? So, where is it?' Ultimately, the expert believes a nuclear reactor on the moon could take up to 20 years to become a reality. NASA would need a working launch vehicle, a small and adaptable reactor, and the ability to land on the moon. Right now, the SpaceX Starship is the only vehicle option – but it has exploded during several of its test flights. NASA has been working with Boeing on a Space Launch System - the main competitor to Space X's Starship - but that program would be canceled under the Trump administration's proposed cuts which slash 24 percent from NASA's overall budget. Landing on the moon is no picnic, and attempts by Japanese space companies in 2023 and 2025 ended in crashes. There are also the scientific and technological advances needed for the nuclear reactors. The reactors must be able to withstand harsh conditions on the moon, including temperatures swings from 250 degrees Fahrenheit during the day to minus 400 degrees at night. 'Small modular nuclear reactors, it turns out, are always just around the corner – a corner you never get to turn,' Cirincione said. Many scientists and nuclear energy experts have shared in Cirincione's skepticism. Dr. Kathryn Huff, a former nuclear energy official at the U.S. Department of Energy, and professor at the University of Illinois at Urbana-Champaign, wrote in a Bluesky social media post that she's not 'bullish' on 'unrealistic timelines.' 'The 2030 target does not align well with recent budgetary trends…' she explained in a statement, shared by the university. 'Accelerating the FSP program could come at the expense of other critical priorities, including earth science, climate observation and space-based weather forecasting – all core elements of NASA's public-serving mission.' Dr. Alfredo Carpineti, an Italian astrophysicist, wrote in IFLScience this week that the proposal is 'unfeasible.' 'Even if we allow landing the nuclear reactor on December 31, 2030, the timing is really too short for something that must not have any faults if you want to operate it safely,' Carpineti wrote. Others were more optimistic about NASA's accelerated timeline. Sebastian Corbisiero, a senior program manager at Idaho National Laboratory who leads the Energy Department's space reactor program, told The Independent that a nuclear reactor on the moon is 'doable' by 2030. 'Nuclear reactor technology has been around for decades, so its well known,' he said. 'Some key differences with a space reactor is that it needs to fit on a rocket, so there are mass and volume requirements; and that the system needs to operate in vacuum – so components will need to be built to survive that environment.' Dr. Bhavya Lal, a former associate administrator for technology, policy, and strategy at NASA, and former aerospace executive Roger Myers, recently argued that it would be possible to have nuclear reactor on the moon by 2030, and it would take $3 billion to do so. 'It's possible, but it will require serious commitment,' Lal told The Independent. But even if plans are speeded up, Lal says there's no need to worry about the prospect of the moon blowing up. It's 'simply not grounded in science,' she said.
