Weight loss is usually considered a good thing, unexpected and extreme weight loss can be a sign of something in your body going very wrong. There could be some underlying issues that are causing your body to pull weight and nutrition from your muscles and body fat to keep you going. As you grow old, your limbs grow weaker, and same for your muscles, so you do lose some weight as you age, but losing a lot of it too quickly could be a sign of something much worse, Dementia. A recent study published in JAMA Network Open 2025 Cardiometabolic Trajectories Preceding Dementia in Community-Dwelling Older Individuals, has identified potential early indicators of dementia, including significant weight loss and specific digestive changes, appearing years before noticeable cognitive decline.

The study showed that people who later got dementia had their Body Mass Index, or BMI, go down faster than those who stayed healthy. BMI is a way to see if someone's weight is healthy for their height. This drop in BMI started happening many years before they were told they had dementia, sometimes as early as 11 years ago. Also, these people often started with a lower BMI to begin with. So, even though everyone's weight might change a little as they get older, the people who developed dementia had a much bigger and faster weight loss.

What Are Some Other Indicators Of Dementia?

Along with their BMI, the size of their waist also changed. People who ended up with dementia had smaller waist sizes, and this difference was noticeable about 10 years before they were diagnosed. This means that their bodies were changing in ways that showed up long before they or their doctors noticed any problems. So, not only was there weight loss, but also a loss of abdominal fat. This measurement is important because fat around the waist can be related to other health issues.

The study also found changes in their blood. Specifically, the "good" cholesterol, called HDL, went up in people who developed dementia. This increase happened about five years before they were diagnosed. It's tricky because HDL is usually seen as a good thing for your heart. But in this case, it seems like it might be a sign of changes happening in the brain. Scientists are still trying to understand why this happens.

Weight Loss Doesn’t Cause Dementia, Dementia Causes Weight Loss

When we see that people with dementia lose weight, it's easy to think that the weight loss is what caused dementia. But experts think it's the other way around. They call this "reverse causation." This means that the brain changes that cause dementia also cause people to lose weight. The brain changes can affect things like appetite, how the body uses food, and how people go about their daily lives. For example, people might forget to eat, have trouble making meals, or move around less.

While the study revealed a lot about different indicators of dementia and bodily changes, there are many limitations to the study. Everyone loses some weight as they get older. So, it's hard to know when weight loss is just a normal part of aging and when it's a sign of dementia. The study found that people with dementia lost weight faster, but it's still tricky to tell the difference in everyday life. Doctors need to look at other things, like memory tests, to figure out if someone's weight loss is a cause for concern.

If someone is losing weight without trying, and they're also having problems with their memory or thinking, it's important to talk to a doctor. It's not just about the weight loss; it's about the whole picture.

The NHS will not be automatically inviting all men above a certain age to check for prostate cancer, unlike the approach for some other cancers. The UK National Screening Committee has suggested that the prostate-specific antigen (PSA) test should only be actively offered to men carrying the BRCA gene mutation, which increases their risk. Still, men can request a PSA test from their GP in certain situations.

Olympic cycling hero Sir Chris Hoy, who has received a terminal diagnosis, is among those campaigning for men with known risk factors to be invited for a PSA test at a certain age, even if they do not have any symptoms.

Prostate Cancer Screening: What Is The PSA Test?

A prostate-specific antigen (PSA) test checks the level of PSA in your blood. PSA is a protein produced by the prostate, a small gland in the male reproductive system located just below the bladder. The prostate produces the fluid part of semen.

The NHS says the test might be suggested if you notice symptoms that could point to prostate cancer, such as:

• urinating more often than usual, feeling a sudden urge to pee, or waking up frequently at night to urinate
• blood in your urine
• difficulty getting or maintaining an erection

However, for most men, urinary symptoms are caused by something other than cancer.

A PSA test is usually carried out at a hospital or GP surgery by a nurse or other healthcare professional. Men are asked to avoid certain activities for 48 hours before the test, as these can temporarily raise PSA levels and affect the result. Activities to avoid include anything that leaves you out of breath, like strenuous exercise.

If a man’s PSA level comes back high, they may be offered a repeat test to see if the levels remain raised. If they do, the GP may refer them to a specialist for further investigations, such as a biopsy or an MRI scan.

Prostate Cancer Screening: Why Is The PSA Screening So Controversial?

PSA levels can rise for many reasons, including minor infections, and around 75% of men with a raised PSA do not have prostate cancer. A high reading can lead to referrals for unnecessary biopsies or MRI scans, or treatment for tumours that might never have caused harm.

The PSA test can also miss aggressive cancers. Research has shown that roughly 15% of men with a normal PSA result may actually have prostate cancer.

Prostate Cancer Screening: Who Can Currently Get The PSA Test?

Routine PSA testing is not offered as standard on the NHS. You might be offered a test if a doctor suspects symptoms that could indicate prostate cancer. Men undergoing treatment for a prostate condition may be offered regular PSA checks to monitor how treatment is progressing.

Men aged 50 and over can request a PSA test from their GP, even without symptoms. Campaigners say many men are unaware that they are at higher risk of prostate cancer and should be actively encouraged to think about having a PSA check.

Prostate Cancer Screening: Who Else Could Get It?

If the UK National Screening Committee’s recommendation is approved by the Government next year, men with the BRCA gene mutation could also be invited for a PSA test. Men who think a family member might have had the BRCA gene mutation can request a genetic test on the NHS to find out.

Alzheimer's disease is the most common cause of dementia. As you may know, It is a physical illness that causes the brain to gradually stop functioning correctly, leading to a decline in memory and thinking skills. Alzheimer’s is not just a condition that affects not only memory but also many aspects of daily life, including behavior patterns, routines, and speech.

According to Alzheimer’s Society, the disease is affecting more people than ever: roughly one million people in the UK currently have dementia, a figure expected to rise significantly by 2050.

Catching Alzheimer's early is key to ensuring patients and caregivers receive the right medical care and support. One of the best ways to spot the beginning of mental decline is by noticing changes in how a person uses language and speaks.

5 Speech Clues That May Signal Early Alzheimer's

New speech problems are often one of the first indicators of the disease. Here are five subtle signs to watch out for:

Pauses, Hesitations, and Vagueness

People often have trouble finding the exact word they want to use. This causes them to stop frequently, leading to long pauses and hesitations while speaking. When they can't remember the word, they might use very general words like "thing," or they will try to describe what the forgotten word is, they will describe the forgotten word instead of saying it directly.

Using Incorrect but Related Words

A person might replace the correct word with one that is somehow connected to it. For instance, if they mean to say "fork," they might mistakenly say "spoon" because both are common eating tools. In the very early stages, they might use a general category word, like saying "animal" instead of the specific word, "cat."

Talking About a Task Instead of Doing It

When someone needs to start a task, they may struggle to begin or complete it. Instead of discussing the actual steps needed, they talk about their feelings. They might say, "I used to be able to do this easily," or "I don't think I can manage it now," showing worry or doubt instead of focusing on the job at hand.

Less Word Variety

The person's language starts to sound much simpler and less colourful. They tend to stick to basic, common words and may repeat the same verbs and adjectives over and over again. They also use connecting words like "the," "and," or "but" very often to link their basic sentences, making their speech sound repetitive.

Trouble Finding Words in Groups (Categorization)

It becomes difficult for them to quickly name things that belong to a specific category. For example, if asked to name five types of food, different parts of the body, or words starting with the letter 'P,' they struggle. This challenge becomes noticeably harder and more frustrating as the disease progresses.

Why Early Detection Matters

While everyone forgets a word now and then, Persistent and worsening problems with memory, fluency, and varied language could be an early sign of Alzheimer's.

Age is the biggest factor for Alzheimer's risk, with the chance doubling every five years after age 65. However, the disease can affect people under 65 (early-onset Alzheimer's). Spotting these speech changes early is especially crucial for people who are already at a higher risk, such as those with Down Syndrome.

Usually, when your muscle hurts, it's just from working out too hard, pulling a muscle, or getting a bruise. The pain is normal and goes away after a while. However, the National Health Service (NHS) wants people to know that some types of muscle pain are not normal and could be a medical emergency.

Muscle cramps and pain are considered normal; you may have hurt your leg by a fall, stretched your muscles wrong etc. However, not all pain is harmless and it can lead to more serious consequences. Here is how you identify whether your muscle pain is in dangerous territory or not.

Signs You Should See A Doctor Immediately

NHS explains that one should get help right away if your muscle pain feels like:

• A "burning pain" (like something hot is inside your leg or arm).
• A "deep ache" that feels very intense and goes deep into the muscle.

It's a major red flag if this pain gets much worse when you try to move the sore body part. If you have these symptoms, doctors worry it could be a serious problem called Compartment Syndrome.

What is Compartment Syndrome?

The strong, thin layer of tissue which holds your muscles is called fascia. A compartment is just one of these tight bundles of muscle, blood vessels, and nerves.

Compartment syndrome happens when something causes a lot of swelling or bleeding inside that bundle. Because the fascia around the muscle doesn't stretch easily, the pressure inside the compartment goes up very fast.

This high pressure squeezes the blood vessels and nerves, stopping blood from flowing properly. When blood can't get in to bring oxygen or out to remove waste, the muscle tissue starts to die. That's what causes the severe pain.

What Are The Symptoms of Compartment Syndrome?

It's important to watch out for these symptoms, especially if they follow an injury or intense activity:

Intense Pain: The pain is severe, much worse than normal soreness. It might feel like a deep, burning ache inside the muscle.

Worse with Movement: If you try to move the sore arm or leg, the pain gets instantly and much worse.

Swelling: The muscle might look puffy, or it might feel rock-hard or tight to the touch.

Odd Sensations: You might feel numbness, a pins-and-needles feeling, or feel weak in your hand or foot.

Tightness: The area feels so tight you have trouble moving it normally.

How is Compartment Syndrome Treated?

If the problem is sudden and severe (Acute Compartment Syndrome), it is an emergency, and doctors must act right away.

The Surgery (Fasciotomy)

The surgeon makes a long cut through the tough skin (the muscle cover) that is squeezing the muscle. This immediately releases the pressure, allowing blood to flow normally again to the muscle and nerves.

Recovery

Afterward, you'll need pain medication, and sometimes a skin graft (taking skin from another part of your body) to cover the large wound. You will also need physiotherapy to help the muscle get back its full movement and strength. Since the pain here is linked to exercise, treatment usually starts with changes to your routine:

• Stop activities that trigger the pain. For example, if running hurts, try riding a bike or swimming instead.
• Use anti-inflammatory medicines (like ibuprofen) to ease the discomfort.
• A physical therapist will teach you special stretches and strengthening moves.
• If you run, wearing special shoe inserts might help.
• If these easy changes don't work after a few months, your doctor might then suggest a small surgery.
