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."

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
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
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
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
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
Bargain prices, easy tick-box applications, or prescriptions with no follow-up, should all be red flags to online shoppers.

I had a stroke two years ago and STILL can't swallow – help!
OUR resident specialist and NHS GP, Dr Zoe Williams, shares her expert advice. Today, 2 Dr Zoe Williams helps Sun readers with their health concerns Credit: Olivia West 2 This week a reader still does not have the ability to swallow following a stroke two years ago Q) FOLLOWING a stroke two years ago at the age of 69, I have total dysphagia and have been peg tube fed since. Everything else is back to normal except the ability to swallow but despite doing all the exercises, given by the Speech and Language Therapy team, nothing has worked. Neuromuscular electrical stimulation therapy is private and expensive. Is there any other treatment available? A) Dysphagia is the inability to swallow, which is why you have been fed via a tube into the stomach. READ MORE FROM DR ZOE I'm sorry to hear that you haven't seen improvement despite support from SALT. NMES aims to retrain the nerves and muscles, and SALT exercises increase effectiveness. But it lacks sufficient robust evidence at the moment to be rolled out. However, it can be used as part of clinical trials or audits. A newer NHS-supported treatment, pharyngeal electrical stimulation, targets the throat's pharynx region. It aims to 'rewire' nerve pathways. Clinical trials (eg, the PHADER study) show it improves swallowing safety and reduces aspiration risk in stroke patients. The NHS is also currently investigating transcranial magnetic stimulation (TMS) aimed to reactivate swallowing centres in the brain. Most read in Health Other therapies include Botox if muscle stiffness is an issue and surgery to dilate the oesophagus. Do request a multidisciplinary reassessment (neurologist and SALT) to explore your options. And do ask about NHS trials.

The TRUTH about Ozemd**k – the bizarre weight loss jab side-effect that's ‘adding inches' to manhood size
OZEMPIC-PENIS sounds like a sexually transmitted disease you really wouldn't want to catch. But it's actually a term that has cropped up online, largely amongst men on Advertisement 4 Men who have been taking Ozempic say they've noticed a change to their penis size, here we reveal all you need to know Credit: Getty One anonymous user wrote: 'I recently measured myself down there and noticed I gained about one inch.' Another asked: 'Increased size, anyone else notice?' Weight loss drugs were first developed to treat type 2 diabetes, and Ozempic is still prescribed for just that. Wegovy and Advertisement They work by mimicking naturally occurring hormones, like GLP-1, that make you feel full, slow digestion and regulate appetite, leading to sometimes drastic fat loss. The health benefits can be huge considering obesity can cause cancer, type 2 diabetes, heart disease, cancer and more. But is it too good to be true that the drugs can add inches to your penis as well? We asked GP and men's health and erectile dysfunction expert Dr Jeff Foster, Medical Director of Can taking weight loss drugs really make your penis bigger? 4 Weight loss jabs can make your penis LOOK bigger Credit: Getty Advertisement THE short answer is no, but the drugs can certainly make your penis LOOK bigger. 'It's true,' says Dr Foster. 'You naturally have a small fat pad just above the base of the top of your penis. What is Erectile Dysfunction? 'As you develop 'It appears, therefore, that everything has shrunk. 'It's as if your penis has gone inside, but all that's really happening is the surrounding tissue to your penis has become more protruded - the true penis size hasn't changed. Advertisement 'And in fact, about 70 per cent of your penis is external, there's another 30 per cent inside that you just never see.' Pre-Ozempic, some men found this illusion so upsetting that they'd be referred for liposuction to have the fat pad reduced. 'The removal of this fat pad just above the penis does make it look bigger, but the problem is, it's not actually any bigger, it's just the appearance of the outward area,' says Dr Foster. Losing some of that fat pad as a side-effect of weight loss drugs can have the same effect though - and doesn't involve a surgical procedure. 'It's a win, isn't it?' says Dr Foster. 'You're going to be healthier, and you might end up looking like you've got a bigger penis. Advertisement 'I mean, no men are ever going to go, 'Ah, I'm really worried my penis is too big'.' Do fat jabs help improve erections too? 4 Fat jabs can help improve erections and your sex drive will go up Credit: Getty 'DEFINITELY,' says Dr Foster 'Fat increases oestrogen levels in men, and it also reduces testosterone and increases insulin resistance. 'All of those three together will have a really negative impact on your testosterone production. Advertisement 'And if you haven't got testosterone, or not as much of it, you don't get a libido, you don't get erections. 'So it's really simple: by reducing your body fat, your erections get better, your sex drive goes up and you feel more manly.' Does that mean weight loss meds could eventually be prescribed for ED? 'IT could be one of your tools as part of an overall arsenal of treating erectile dysfunction (ED), but you wouldn't use it as a primary treatment,' says Dr Foster, who says that crucially you need to find the root cause of the problem. 'The biggest cause of erectile dysfunction in men is still heart disease. 'If you've got narrowing of the arteries you can't get a decent erection. Advertisement 'Your penile artery is almost identical in calibre and design to your coronary artery. 'That's how they discovered Viagra - it was designed for blood pressure in your heart originally, and they found it worked really well down below.' He adds: 'This is why we say to men, if you have got erectile dysfunction, find out why. 'The worst thing you can do is just buy some over the counter tablet without finding out why [it's happening]. 'We say that on average, if you have an arterial cause for erectile dysfunction, you have about a three-year window before something bad happens to your heart, like a heart attack - so really understand the cause.' Advertisement This is when weight loss drugs could make a difference, by supporting overall heart health, and therefore, erection health. 'If we think there's a cardiovascular cause, then using something like Ozempic or Mounjaro could be amazing, because not only do you fix your erection, but you actually fix the underlying process that's causing the whole thing,' says Dr Foster. 'It improves your heart and your penis.' Are there any potential penile risks? 4 The weight loss jabs may however reduce muscle mass, a problem that needs to be managed, whether you're worried about how your penis looks or not Credit: Getty 'I'VE heard the rumour that allegedly GLP-1 drugs may reduce penis size or have adverse effects on male health in general,' says Dr Foster. Advertisement 'The theory behind it is whether testosterone or male wellbeing is affected by GLP-1s.' He explains: 'GLP-1s work by improving satiety, so you eat less. 'By doing that, you reduce body fat, but the other part of that, which we're now seeing evidence of, is that if you're not careful, you also start to reduce muscle mass. 'That's the big worry, because on one hand, yes, you want to get rid of excess fat, but you don't want to reduce your muscle because that's not healthy for anyone.' Loss of muscle can lead to falls, lack of mobility, increased fractures, and in older age, even premature death. Advertisement '[People] think that sarcopenia-effect (muscle loss) is because of lowered testosterone, but it's probably not a direct effect of [GLP-1s],' he explains. Muscle loss is a problem that should be managed though, whether you're worried about how your penis looks or not. 'If you are going to be taking a weight-loss drug and want to maintain your masculinity, then you have to make sure you eat enough protein and do weight bearing exercise,' says Dr Foster firmly. 'You must do both, and that will help your erections, because we are starting to see the effects of weight loss drugs causing loss of muscle and that's having massively negative impacts on male health. 'To maintain your testosterone, to maintain your erection, make sure you do some decent exercise, and make sure you eat enough protein, even if you don't feel like it, because otherwise you're going to lose more important things [than fat alone], like sexual function and muscle.' Advertisement What is erectile dysfunction? ERECTILE dysfunction - also known as impotence - is very common, especially in men over 40. Erectile dysfunction is when you are either: Unable to get an erection Unable to keep an erection for long enough to have sex Depending on the cause, you may still be able to get an erection at other times, such as when you wake up. Sometimes you might also have low sex drive. It's not usually the sign of something serious but you should speak to a GP about it, especially if it's causing you distress. Possible causes include stress, tiredness, having too much booze, as well as some medicines. But if your ED is persistent, it might be caused by: High blood pressure or high cholesterol Diabetes Depression or anxiety Hormone problems

The 8 reasons you have awful hangovers even after just TWO drinks – and the must-do hacks to avoid it
APEROL spritz at the Saturday BBQ, rosé after work and G&Ts in the garden - summer is here, but with booze comes the dreaded 'next day'. What's worse, is that sometimes, it can only take a couple of drinks to feel the effects of a hangover. Advertisement 7 Waking up feeling rough after just a couple? You're certainly not alone! Credit: Getty Laura Jennings, nutritionist and founder of the ' But, there are some reasons why you might end up suffering the next day, even if you kept your alcohol intake to a minimum… 1. You're dehydrated DRINKING water is the number one rule of avoiding a hangover. Advertisement Read more life hacks So, if you're not doing it, there's your first clue as to why you feel it even after a couple. While drinking water won't stop you getting a hangover, it could help reduce the severity of your symptoms, Laura says. She adds: 'Alcohol acts as a diuretic, meaning it encourages your body to lose more water through urine. 'It does this by blocking the antidiuretic hormone vasopressin, which normally helps your body regulate water excretion.

And make sure to hydrate on route home. 2. Your drinks are dark NOT all alcohol affects you the same way when it comes to hangovers. Advertisement 7 Make sure to drink water throughout the evening AND once you get home Credit: Alamy 'Clear spirits such as vodka and gin tend to cause fewer symptoms because they contain lower levels of congeners, which are compounds produced during fermentation and distillation,' says Laura. In people who are susceptible, a spike in histamine and serotonin can lead to symptoms such as flushing, headaches or nasal congestion Laura Jennings nutritionist and founder of the NutriMethod 'Some of these congeners, like methanol, can be broken down into toxic substances such as formaldehyde and formic acid in the body,' says Laura. Advertisement 'Thankfully, our body has enzymes that help clear these toxins out, but if you've had a lot to drink, or you're dehydrated, the system can get overwhelmed, which may contribute to the severity of a hangover.' 3. You drink red over white IF you're a red wine over white kind of a drinker then your hangover might be worse. Red wine has more of those pesky congeners than white, Laura says, adding: 'Red wine also contains more histamine and serotonin-releasing compounds than white wine or spirits like vodka. 7 Go for white wine over red- which has more chemicals that induce a hangover Credit: Alamy Advertisement 'In people who are susceptible, this spike in She adds that red wine also contains more quercetin, a polyphenol (antioxidant) found in significantly higher amounts in red wine. Research in the journal Scientific Reports suggests that quercetin might interfere with alcohol metabolism, especially in people with a variant of the enzyme ALDH2 (aldehyde dehydrogenase 2). 'This enzyme helps break down acetaldehyde, a toxic byproduct of alcohol,' Laura says. Advertisement 'If this process is slowed or impaired, acetaldehyde can build up, leading to more severe hangover symptoms like headache, nausea and fatigue.' 4. Your diet is filled with UPFs Laura says: 'These foods provide little in the way of protective micronutrients and can amplify inflammation and blood sugar swings, both of which can intensify hangover symptoms.' Drinking alcohol can mess with your Advertisement Women have less body water and lower levels of alcohol dehydrogenase, an enzyme that metabolises alcohol Dr Mohammed Najjar Medical Director of Jorja Healthcare Group 'This can lead to dips in blood glucose, which might explain why people feel shaky, tired or irritable after drinking,' says Laura. Drinking on an empty stomach could also make your hangover worse. But, on the flip side, Laura adds: 'Eating nutrient-dense, whole foods rich in B vitamins and minerals like zinc before drinking may help take the edge off a hangover.' Research in the journal of Clinical Medicine found that vitamin B3 and zinc play a pivotal role in reducing the severity of hangovers, especially when it comes to symptoms like nausea and vomiting.

Dr Najjar says: 'Although men and women tend to metabolise alcohol at approximately the same rate, women appear to have a higher rate of alcohol elimination.' This can mean women feel the effects of alcohol more strongly. Advertisement 'This could be due to a number of factors such as the smaller lean body mass in women which leads to higher alcohol concentration per unit of lean body mass, and also due to the fact that women have less body water and lower levels of alcohol dehydrogenase, an enzyme that metabolises alcohol,' adds Dr Najjar. The Dr Najjar says that some women notice their hangovers are worse during the luteal phase (the week before your period). 'Levels of the hormone progesterone levels increase significantly during this phase, and oestrogen levels also remain elevated,' says Dr Najjar.

Unhealthy, high calorie foods could derail you weight loss efforts as well as make the hangover worse. Shona Wilkinson, Nutritionist at Onions and garlic Both of these foods contain a nutrient called sulphur, according to Shona, which is essential in liver detoxification. 'Toxins in the body essentially join to the sulphur and are then excreted from the body.' Lemon peel Adding some lemon peel to a glass of water or shaving some onto your food could help alleviate some of your hangover symptoms. Shona says: 'Lemon peel contains a substance called limonene, which helps your body to detoxify itself by removing carcinogens from the body. 'There is research that suggests lemon peel may even offer an effective solution to migraines and headaches, given that it's a great source of Vitamin C.' Grapefruit It's the substance naringin in grapefruits, which helps to protect the liver from all kinds of damage. Shona says: 'There are a lot of medicines out there that don't mix too well with grapefruit however, so consult your GP before adding too much grapefruit into your diet if you're on any prescribed medications.' Pickle juice An odd one, but pickle juice is packed with electrolytes like sodium and potassium, which Shona says are essential in a whole host of the body's vital processes. She says: 'Electrolytes help to keep us hydrated by regulating the amount of water in our cells to ensure they're able to function properly. 'If you're hungover, it's the perfect remedy.'
