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.

As winter transitions into warmer summer months, many people notice a sudden worsening of dandruff. During colder months, dandruff often appears as dry, fine flakes due to scalp dryness. However, as temperatures rise and humidity increases, dandruff can become oily and sticky because of increased sweating and sebum production. This seasonal shift highlights that dandruff is not limited to a particular time of year; rather, changes in climate can disrupt scalp balance and trigger flare-ups. Dr. Anupriya Goel, MBBS, MD, DPD (UK) – Dermatology, answered this for us.

Why does dandruff recur?

Many people struggle to understand why dandruff keeps recurring. It is often treated as a temporary cosmetic concern, but in reality, dandruff is a chronic scalp condition that requires consistent care and appropriate treatment. The primary cause of dandruff is a yeast called Malassezia globosa, which naturally resides on the scalp. This microorganism feeds on sebum (the natural oils produced by the scalp). As it breaks down these oils, it releases by-products that can irritate the scalp, leading to inflammation, itching, and visible flaking.

Seasonal factors further aggravate this process. In winter, cold air, low humidity, indoor heating, and frequent hot showers can strip the scalp of its natural moisture and weaken the skin barrier, resulting in dryness and flaking. In contrast, summer brings increased sweat and oil production. The combination of humidity, sweat, and sebum creates an ideal environment for Malassezia to multiply, which can worsen dandruff symptoms.

What are the external factors responsible for dandruff?

Environmental factors such as pollution can also settle on the scalp and contribute to irritation. In addition, daily habits like wearing helmets for long hours, tying up damp hair, or not cleansing the scalp regularly can further disrupt scalp health. The transition period between seasons is often the most challenging, as the scalp has limited time to adapt to changing environmental conditions.

Because dandruff is often mistaken for a temporary issue, many people rely on occasional treatments or home remedies. However, effective management typically requires regular scalp-focused care using clinically proven active ingredients.

Treating dandruff

One such ingredient commonly used in anti-dandruff formulations is Piroctone Olamine, an antifungal agent that helps control the growth of Malassezia on the scalp. By reducing fungal proliferation, it helps address the underlying cause of dandruff and can assist in decreasing flaking, itching, and scalp irritation. It also helps cleanse the scalp by removing excess oil and buildup while being relatively gentle on the hair and scalp.

For optimal results, individuals experiencing recurrent dandruff may benefit from incorporating an anti-dandruff shampoo containing Piroctone Olamine into their regular hair care routine. Consistent use is important for maintaining scalp balance. During periods of increased sweating, such as in hot and humid weather, washing frequency may be increased as needed. Maintaining hygiene practices such as regularly cleaning helmets, pillowcases, and hair accessories can also help minimise recurrence.

In addition to controlling dandruff, well-formulated shampoos containing Piroctone Olamine are often combined with conditioning and moisturising ingredients that help maintain hair softness and scalp comfort while supporting long-term scalp balance.

World Autism Awareness Day is observed on April 2 every year, a day to spread awareness about autism, its causes, symptoms, and what parents can do to help their children. But even when it comes to autism, there is a great deal of prejudice surrounding the disorder, which often forces parents into a state of denial. A condition which initially comes across as a personality trait—shyness, for instance—is usually diagnosed late. Dr Hamza Hussain, Head of the Department of Psychiatry and Mental Health at Ruby Hall Clinic, Pune, in an interview with Health and Me, explained how parents can spot the signs of autism early in their children.

How to know if your child is autistic or just shy?

It is completely understandable for parents to feel worried when they notice delays in their child’s speech, social engagement, or behaviour. That said, it is important to recognise the differences between early indicators of Autism Spectrum Disorder (ASD) and other developmental patterns or conditions.

Children who may be on the autism spectrum often display ongoing difficulties with social communication and interaction. They might avoid making eye contact, not consistently respond when their name is called, show delays in speech, or find it challenging to engage in two-way conversations. Repetitive actions—such as hand movements, arranging toys in a particular order, or insisting on strict routines—can also be early indicators. On the other hand, children with ADHD are usually more socially responsive but may struggle with focus, impulsive behaviour, and high activity levels. A speech delay alone does not necessarily point to ASD, especially if the child shows good non-verbal communication like gestures, expressions, and social interest.

What are ASD patterns?

One important way to tell the difference is by observing patterns over time. Signs of ASD tend to be consistent across different situations and environments, whereas other behaviours may change depending on the child’s mood, surroundings, or level of stimulation.

Support at home plays a vital role in a child’s development. Simple, consistent interactions can go a long way. Spending time in face-to-face play, encouraging eye contact, and talking through daily activities can strengthen communication skills. Reading stories, singing rhymes, and using gestures can further aid language development. It is also helpful to limit screen exposure, as too much screen time can impact attention span and social learning.

How can parents help?

Having a structured daily routine can help children feel more secure, while encouraging and praising positive behaviours can reinforce learning. Above all, recognising concerns early and seeking timely intervention can significantly improve outcomes. If parents feel uncertain about their child’s development, consulting a professional early on can provide clarity and the right support for the child’s growth.

Autism in women is not often entirely recognized because this disorder does not always have to correspond to the “classic” picture characteristic of males.

The diagnosis is based on a male criterion with such behavior as obvious withdrawal from a group, overtly displayed repetitive behaviour, and limited interests. There can be mild social deficit or internalized anger and frustration that can pass unnoticed in clinical practice.

The Art of Masking

One of the most significant reasons behind underdiagnosis is masking (also called camouflaging). Masking is one of the most significant reasons for underdiagnosis. This is helpful in masking but also covers or conceals essential symptoms.

Masking causes mental exhaustion, anxiety, and burnout, but it does not address the underlying autism and leaves it undiagnosed.

Stereotypes And Gender Bias

There is a strong societal stereotype that autism is a “male condition”. This bias is felt by parents, teachers, as well as health care professionals.

Sex bias is evident in that boys get referred for evaluation early. Girls are often tagged “shy,” “sensitive,” and “introverted.”

Their struggles are normalized instead of being explored for any issues. Gender bias is a significant contributor to delayed or wrong diagnosis.

Different Interests, Less Suspicion

A restricted interest is another hallmark of autism, but in women, it tends to be more socially acceptable. Their interests conform to the norms of society; they do not predispose clinical suspicion as opposed to more masculine interests like mechanical systems or numbers.

Overlap With Other Conditions

Autism in women being misdiagnosed as other psychiatric disorders is due to symptom comorbidity. Some of the common misdiagnoses are:

• anxiety disorders,
• major depressive disorder,
• borderline personality disorder,
• eating disorders.

In many cases, these are secondary to autism as a result of years of living with undiagnosed autism.

Social Expectations And Conditioning

From an early age, girls are often conditioned to be socially attentive, empathetic, and compliant. This societal conditioning pushes autistic girls to adapt and hide their difficulties.

These may include forcing themselves into socializing. Fitting in is deemed more important than comfort. They end up creating coping mechanisms that mask their difficulties.

While this may benefit outward functioning, it postpones the recognition of underlying neurodevelopmental differences.

The Consequences of Late Diagnosis

Delayed diagnosis or missed diagnosis has the following effects:

• Chronic mental illness
• Low self-esteem
• Confusion about identity
• Inadequate support services
