According to a study published in the November 6, 2024, online issue of Neurology, the medical journal of the American Academy of Neurology, older people who are sleepy during the day or lose interest in activities due to sleep issues may be more likely to develop a syndrome that can lead to dementia.
People with the syndrome walk slowly and report memory problems, but they do not have a mobility handicap or dementia. Motoric cognitive risk syndrome is a condition that can develop before dementia.
The study found that people with excessive daytime sleepiness and a lack of enthusiasm to get things done were more likely to develop the syndrome than people without those sleep-related issues. The study does not prove that these sleep-related issues cause the syndrome, it only shows an association.
“Our findings emphasize the need for screening for sleep issues,” said study author Victoire Leroy, MD, PhD, of Albert Einstein College of Medicine in the Bronx, New York. “There’s potential that people could get help with their sleep issues and prevent cognitive decline later in life.”
The study included 445 participants, with an average age of 76, who did not have dementia. Participants completed sleep surveys at the beginning of the trial. They were queried about memory problems, and their walking pace was measured on a treadmill at the beginning of the study and then once a year for the next three years.
The sleep assessment included questions about how frequently people had difficulties sleeping because they woke up in the middle of the night, couldn't fall asleep within 30 minutes, or felt too hot or cold, as well as whether they used sleep aids. The question to assess excessive daytime drowsiness asks how frequently people have had problems remaining awake when driving, eating meals, or were engaged in any other activity.
In total, 177 participants fit the category of bad sleepers, whereas 268 satisfied the definition of good sleepers.
At the outset of the trial, 42 participants had motoric cognitive risk syndrome. Throughout the trial, 36 more persons got the condition.
35.5% of patients who experienced extreme daytime sleepiness and a lack of enthusiasm developed the syndrome, compared to 6.7% who did not. After accounting for other factors that could influence the risk of the syndrome, such as age, depression, and other health conditions, researchers discovered that people with excessive daytime sleepiness and a lack of enthusiasm were more than three times more likely to develop the syndrome than those who did not have those sleep-related issues.
“More research needs to be done to look at the relationship between sleep issues and cognitive decline and the role played by motoric cognitive risk syndrome,” Leroy said. “We also need studies to explain the mechanisms that link these sleep disturbances to motoric cognitive risk syndrome and cognitive decline.”
A limitation of the study is that participants reported their own sleep information, so they may not have remembered everything accurately.

Seasonal factors can aggravate dandruff. (Photo credit: iStock)
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.
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.

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.
Children living with autism often struggle with social interactions. (Photo credit: iStock)
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.
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.
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.
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.
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.
Autism in women being misdiagnosed as other psychiatric disorders is due to symptom comorbidity. Some of the common misdiagnoses are:
In many cases, these are secondary to autism as a result of years of living with undiagnosed autism.
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.
Delayed diagnosis or missed diagnosis has the following effects:
