Dementia. It is a brain condition that causes loss of cognitive function, which includes thinking, remembering and reasoning. It can also affect a person's ability to perform daily activities. It is a progressive neurological condition, which means the ability to communicate, or to perform cognitively deteriorates with time. You can delay the deterioration, but cannot stop it. But how does one delay the progress without knowing that it is happening? Well now, this can be achieved as Scottish researchers are working on a new AI tool that uses high-street opticians to spot early signs of dementia.

Now, dementia can be diagnosed through an eye test.

AI, Eye Test, And Dementia

Scottish scientists from the NeurEye research team have found that photographs taken of the retina at the back of the eye can indicate of brain health. It is done using AI software to analyze the information. Scientists also use this to spot signs of diseases before any symptoms are even experienced.

The team of scientists has collected a million eye scans from opticians across Scotland, which is also the largest data set of this kind. With the help of AI, they have developed an algorithm that can assess the health of the blood vessels in the eye that indicates neurogenerative diseases.

The database built by the team can be applied to photographs taken during routine eye checkups and could be used by clinicians to prevent diseases from occurring. It could also help them in diagnosing conditions at an earlier stage than what they currently can.

How It Works?

The blood vessels in the eye are small and fine, which means they show up conditions earlier than any other part of our body. Balijean Dhillon, who is part of the research group led by the University of Edinburg and researchers from Glasgow Caledonian University said that eyes can reveal more than was thought possible.

All the systems of the body are represented in eye. In fact, the diseases like cataracts, glaucoma, macular degeneration, problem with vision could also detect vascular system, heart health, high blood pressure, diabetes and even neurological conditions. While some of these conditions may show up late, eye care can detect it way before. The earlier you find it, the better it is for you to be able to delay the deterioration.

What Is Dementia?

Dementia is an umbrella term to describe diseases that cause people to lose their cognitive functions. These diseases gradually progress decreasing the ability for someone to function in daily life and take care of themselves. There are some medications used to delay the onset of it and to manage it. People can reduce the chances of developing it by following a healthy diet and lifestyle.

Types of Dementia

Different types of dementia occur due to different reasons. Some types of this disease are:

Alzheimer’s Disease

Alzheimer’s disease occurs when two abnormal proteins (tau and amyloid protein) build up in the brain. Some of its diseases include mental confusion, short-term memory loss, and personality and behaviour changes. In later stages, people may start having trouble talking, recalling distant memories and have issues with walking.

Vascular Dementia

Vascular dementia may occur because of a stroke or atherosclerosis. Atherosclerosis is the hardening of the arteries from plaque building up gradually inside of them. It blocks and damages blood vessels in the brain. This disease has symptoms such as memory problems, confusion, concentration problems and difficulty in completing tasks.

Mixed Dementia

Mixed dementia is a combination of two or more types of the disease. Sometimes, Alzheimer’s disease combined with vascular dementia causes mixed dementia. The health condition usually declines faster in people with mixed dementia than those who only have one type.

Huntington’s Disease

A mutation in the huntingtin(HTT) gene causes a breakdown in the brain’s nerve cells and it is responsible for Huntington’s. This disease causes body movement control problems, trouble thinking, decision-making, memory trouble and personality changes.

Traumatic Brain Injury

Someone may develop dementia-like symptoms if they suffer from repeated physical trauma to their head. Symptoms may appear after a long time and may include memory loss, behaviour or mood changes, slurred speech and headaches.

Parkinson’s Disease

People who have Parkinson's disease may develop secondary dementia in the later stages. Some of its symptoms are having trouble with thinking or speaking. Patients may have hallucinations and delusions, or suffer from depression.

Normal Pressure Hydrocephalus(NPH)

When Cerebrospinal Fluid(CSF) builds up in the brain’s ventricles the excess build-up harms the brain and this causes Normal Pressure Hydrocephalus(NPH). A brain infection, brain injury, bleeding in the brain or any previous brain surgery can also cause this condition.

This disease has some symptoms such as poor balance, forgetfulness, and short attention span, loss of bladder control, frequent falls and mood swings.

Infections

Some infections such as HIV infection, syphilis as well as Lyme disease can cause dementia-like symptoms. Urinary Tract Infections or UTIs, and lung infections can cause symptoms that match dementia.

Central Nervous infections and brain infections can cause cognitive symptoms. Also, COVID-19 symptoms include acute delirium or brain fog.

An 18-year-old Sreenanda from Kerala, India, died after months of adhering to a radical water-only diet based on videos from YouTube. Her treating doctor, Dr. Nagesh Prabhu, said the teenager had anorexia nervosa, a serious eating disorder, which went un-diagnosed and un-treated until it was too late.

Despite having been put on a ventilator during her last days, the extended deprivation of nutrients had already done its permanent damage- malnourishment, a significantly reduced stomach and esophagus, and near-critically low sodium and blood sugar levels that were impossible to correct through medicine.

This tragedy is not only a local news item. It is symptomatic of a spreading, international public health and mental health issue—how eating disorders such as anorexia are misperceived, dismissed, and compounded by online misinformation and social pressure.

What Is Anorexia Nervosa?

Anorexia nervosa is not just a diet that has gotten out of control—it is a severe mental illness with potentially life-threatening results. People with anorexia usually develop a distorted view of their body and an extreme fear of gaining weight, even when they are underweight or starving. This psychological disorder results in restrictive eating habits, compulsive behavior regarding food and exercise, and, in most instances, the refusal to accept the seriousness of their health.

It impacts both males and females, although it is more common in teenagers, who are more likely to be subject to peer pressure, social media ideals of beauty, and emotional instability during their teen years.

Dr. Prabhu discovered that Sreenanda had started displaying signs of extreme food restriction some six months prior to her death. Her family, however, misunderstood her condition and dismissed it as a characteristic of a typical adolescent. As with most others who suffer from anorexia, she had learned to conceal the severity of the illness.

"Eventually, patients lose the sensation of hunger," explained Dr. Prabhu. "Her sugar and sodium levels had dropped to levels that were uncorrectable. She was starving almost." Compounding the issue was the reach of untested diet content from YouTube, which misledly promoted water fasting as a fast and safe method for weight loss.

This misinformation cost Sreenanda her life—and highlights the risk of unmonitored diets and the need for mental health education surrounding eating disorders.

Symptoms That Should Never Be Ignored

The indications of anorexia are more than physical—they're behavioral and emotional. Symptoms include:

• Severe weight loss or inability to gain expected weight.
• Fatigue, dizziness, and intolerance to cold.
• Swelling of limbs, stomachaches, constipation.
• Insomnia, irritability, and mood swings.
• Obsessive food behaviors—such as skipping meals, eating exclusively "safe" foods, or exercising compulsively.
• Low self-esteem, social isolation, and a strong fear of gaining weight.
• In women, cessation of menstrual periods without the use of birth control.

If the body is starved, brain function also breaks down, making it more difficult for people to realize the extent of their malady. This usually brings with it refusal to seek treatment and an even more precipitous decline.

What are the Risks of Anorexia?

The medical effects of anorexia extend far beyond being underweight. Chronic malnourishment can lead to:

• Anemia
• Bone thinning and bone fractures
• Kidney and liver failure
• Irrregular or slowed heart rate
• Low blood pressure
• Multi-organ failure
• Brain atrophy
• Death from heart-related complications or suicide

As reported by the National Association of Anorexia Nervosa and Associated Disorders (ANAD), anorexia has the second-highest death rate among all mental disorders, only beat by opioid dependence. Eating disorders kill over 10,000 people annually in the U.S., and suicide accounts for 24% of deaths related to anorexia.

Anorexia, when detected and addressed early, is controllable and even reversible through appropriate intervention consisting of nutritional rehabilitation, medical attention, and psychotherapy. The disorder, though, being of a specific kind, means many of its sufferers do not respond to it being addressed. They deny illness, think they remain overweight, or are afraid treatment will compel them to become obese.

Family, teachers, and friends are important in recognizing early warning signs and stimulating prompt medical assistance. Procrastination can be lethal.

Can Anorexia Be Prevented?

Although anorexia cannot be prevented with certainty, professionals concur that encouraging healthy food attitudes, body image, and self-esteem in early life will substantially lessen the risk. This entails:

• Promoting activities and accomplishments unrelated to looks.
• Practicing balanced eating and positive body image within the home.
• Reducing exposure to negative or unattainable beauty standards on the internet.
• Being wary of diet or health fads on social media sites.

In Sreenanda's case, it was a mixture of web misinformation, unresolved mental health issues, and failure of early intervention that led to her death. Her tale serves as a graphic reminder that eating disorders are no phase or a choice of lifestyle—these are life-threatening conditions that need specialized attention.

If you or someone you know is experiencing an eating disorder, get help now. Recovery is possible—with care, understanding, and prompt action.

It's 7 a.m., and your day has barely begun, and yet you're already multitasking with a 10-step skincare regimen of foaming cleanser, toner, essence, serum, eye cream, moisturizer, facial oil, sunscreen and don't even get me started on that jade roller and overnight mask from the night before. Ringing any bells? You're not alone.

With wanting a flawless glass skin and TikTok-driven beauty hacks, skincare has evolved from a self-care ritual into what feels like a full-time job. From the 7-step Korean regimen to multi-layered product cocktails touted by influencers, the pressure to “do it all” is real. We’ve been led to believe that more products mean better skin but what if that’s not the whole truth?

Welcome to the world of minimalist skincare, where less isn’t just more, it’s smarter. This article explores the growing shift away from overwhelming routines toward a simpler, science-backed approach to skincare that actually gives your skin room to breathe. Let’s dive into why doing less might just be the best thing you’ll ever do for your skin.

In a world of complicated 10-step skin regimens, the minimalist skin movement is generating a subtle revolution. While bathroom counters are drowning in cleansers, serums, masks, and exfoliators, an increasing number of consumers are demanding to know: do we really need all of this? Driven by science, sustainability, and healthy skin, minimalist skin presents a healthy, results-based alternative to beauty excess.

What is Skin Minimalism?

Skin minimalism isn't about doing the bare minimum or neglecting something—it's about doing what counts. This emerging philosophy is about stripping back your routine to just a handful of must-do steps, prioritizing quality ingredients rather than quantity. By cutting back, you're giving your skin permission to reset, breathe, and get its natural rhythm back.

Rather than applying five serums and following fad beauty trends, skin minimalists stick to a routine that is consistent, evidence-based. That involves fewer actives, less trial and error, and more faith in the skin's natural capacity to repair and regenerate—if supported correctly.

Dermatologist Dr. Kiran Sethi calls it a "skin-first mindset." “It’s not about less effort, it’s about smarter choices. You’re focusing on what the skin truly needs and avoiding the noise,” she says.

The 3-Step Skincare Routine

At the core of minimalist skincare is the three-step skincare routine: cleanse, moisturize, and protect. These steps support skin health at a foundational level.

1. Cleanse

A mild cleanser wipes away dirt, oil, and impurities without upsetting the skin's own moisture barrier. Harsh detergents and over-washing can cause dryness and irritation, so there is an argument for fewer, milder washes—particularly in the morning.

2. Moisturize

Select a mild, fragrance-free moisturizer appropriate for your skin type. Dry skin types should seek humectants such as glycerin or hyaluronic acid; oily skin types should use gel-based products. Toners are not necessary but must be hydrating and non-irritating if used.

3. Sun Protection

No skincare routine would be complete without sunscreen. A broad-spectrum SPF of at least 30 not only shields against premature aging and sunspots, but also guards your skin against dangerous risks such as skin cancer. Even minimalist routines never omit this step.

A core component of minimalist skincare is skin fasting, or the act of giving up skincare products completely in order to reboot the skin. Similar to the way intermittent fasting affects the body, skin fasting has the ability to rebalance sebum production, curb inflammation, and restore the barrier function.

To begin, you can try eliminating one product at a time and see how your skin reacts. Throughout this reset phase, hydration (internal and external), sun protection, and gentle cleansing are important. When the skin seems more stable and less reactive, you can then gradually add products back in so that you can see what's really working and what you don't need.

Why is Gen Z Getting Attracted Towards Overdoing Skincare?

Ironically, as skin minimalism picks up steam, a lot of Gen Z consumers are going in the opposite direction. Driven by TikTok trends, influencer routines, and a deluge of product drops, young users tend to get caught up in over-layering active ingredients such as retinoids, AHAs, and vitamin C.

While the ideal may be glassy, blemish-free skin, the reality tends to be heightened sensitivity, breakouts, and a weakened skin barrier. As dermatologists note, excessive skincare can disrupt the skin's microbiome, stimulate inflammation, and even cause product dependency, wherein the skin becomes unable to self-regulate.

Minimalist skincare, on the other hand, permits the skin to become more resilient in the long run—without growing dependent on perpetual topical intervention.

Minimalist skincare isn't about abandoning results—it's just about selecting evidence-based, multi-tasking products and treatments that bring real transformation without over-stressing the skin.

Dr. Sethi invokes Profhilo, a filler injectable of hyaluronic acid-based, as excellent proof. "It's not volumizing or changing your face; it's hydrating deeply and rejuvenating from within," she says. Profhilo provokes the production of collagen and elastin with little downtime and no layering—a perfect application of minimalist philosophies.

This is future skincare: not glitzy, not involved, but utilitarian and productive.

Minimalist skincare is also a reflection of larger values of conscious living. With fewer products there is less packaging waste, less environmental pollution, and a more eco-friendly beauty regimen. It streamlines not only physical clutter but mental clutter—making your mornings, your money, and your skincare routine easier.

Instead of seeking quick fixes and the latest trends, skin minimalism is about taking a step back, listening in, and making skincare a mindful ritual.

Is Minimalism Right for Everyone?

Although skin minimalism is suitable for most individuals, especially those with sensitive, reactive, or overburdened skin, it will likely need to be adjusted. Individuals with particular skin issues such as acne, rosacea, or eczema must consult a dermatologist before streamlining too extensively.

The concepts, however intentionality, simplicity, and respect for the skin—are universal positives.

Minimalist skincare is not just a trend it's a revolution for your skin rooted in science, sustainability, and simplicity. In an era where more often equates to better, this movement shows that less really can be more.

Who hasn't ever forgotten a friend's name, lost their glasses, or had trouble remembering a word that was just "on the tip of the tongue"? These little memory blips are normal, particularly with age. But with increasing awareness about dementia and cognitive decline, even occasional forgetfulness can raise alarm. Is it just aging or something worse?

Though periodic memory loss is a natural aspect of aging, distinguishing it from the onset of dementia is important to ensure early intervention. Here's a closer examination of when forgetfulness is harmless—and when it might require medical attention.

What are Normal Age-Related Memory Changes?

Aging brings natural changes to our bodies and brains. Known as age-associated memory impairment, these changes are mild and don’t interfere with day-to-day function. According to the World Health Organization (WHO), healthy aging is about maintaining functional ability and well-being even as biological changes occur.

With normal aging:

• You may occasionally forget names or appointments, but remember them later.
• Multitasking becomes harder, and it may take longer to learn new things.
• Concentration can decline, particularly in distracting settings.

These changes are generally more irritating than distressing. Most importantly, most elderly persons maintain independence, functional memory, and the capacity for engaging in meaningful activities.

What are Dementia-Related Memory Changes?

Dementia is not a normal aspect of aging. It is a medical illness that includes a gradual loss of memory, thinking, behavior, and the capacity to carry out daily activities. Alzheimer's disease is the most prevalent type, but there are numerous others—such as vascular dementia, Lewy body dementia, and frontotemporal disorders.

The main differences between aging and dementia:

• In typical aging, you might forget some aspect of an experience. With dementia, whole experiences are forgotten.
• Dementia entails persistent, deteriorating problems with communication, decision-making, orientation, and even personality.
• Healthy older adults are usually conscious of their forgetfulness, but individuals with dementia may not have insight into their own deterioration.

Signs Your Forgetfulness May Be More Than Aging

Some indicators transcend normal memory slips and might signal an underlying cognitive disorder. Let's examine the most revealing differences:

1. Memory Changes

Normal: Occasionally forget names or appointments.

Concerning: Forget recent things, repeat oneself, or get lost in familiar settings.

2. Language Challenges

Normal: Struggle briefly to name something.

Concerning: Often lose train of thought, use wrong words, or have trouble keeping up.

3. Problem Solving & Decision Making

Normal: Need more time to make decisions.

Concerning: Struggle to manage finances, prepare meals, or organize activities previously done easily.

4. Decline in Independence

Normal: Continue with home maintenance and personal care.

Concerning: Need assistance with dressing, bathing, medication, or bill payment.

5. Disorientation

Normal: Remember occasionally where you placed something or the date.

Concerning: Disoriented about place, time of day, or season.

6. Personality & Mood Changes

Normal: Minimal mood shifts in reaction to life events.

Concerning: Unusual irritability, paranoia, or avoiding social activities.

7. Social Withdrawal

Normal: Prefer solitude at times.

Concerning: Refuse interaction because you are confused or cannot keep up with conversation.

8. Lack of Awareness

Normal: Acknowledge your forgetfulness and learn how to make up for it.

Concerning: Deny or are unaware of decline even when pointed out by others.

9. Progressive Pattern

Normal: Changes are not frequent and don't progress quickly.

Concerning: Symptoms become worse—from intermittent lapses to persistent confusion and dysfunction.

Other Causes of Memory Loss You Ought Not to Ignore

All memory issues aren't due to dementia. Some reversible or treatable conditions cause similar symptoms:

• Nutritional deficiencies (e.g., vitamin B12)
• Thyroid or liver dysfunction
• Side effects of medications
• Chronic depression, anxiety, or stress
• Untreated sleep apnea or insomnia
• Head injury or concussion
• Alcohol or drug abuse
• Infections or tumors of the brain

A full assessment by a medical provider is necessary to ascertain the cause.

What Is Mild Cognitive Impairment (MCI)?

Mild Cognitive Impairment occupies the place between normal aging and dementia. People with MCI have observable memory or thought problems that surpass typical age-related decline—but are still capable of independent living. MCI will either stay the same, or in some cases, will worsen to Alzheimer's disease.

Things You Can Do to Help Brain Health

If you or the person you care about is undergoing cognitive changes, these measures will assist in sustaining function and quality of life:

Maintain routines: Regular daily routines aid in memory and minimizing confusion.

Organize yourself: Use notes, calendars, or cell phone reminders.

Challenge your mind: Read, play puzzles, or take up a new hobby.

Stay connected socially: Social isolation may worsen cognitive decline.

Physical exercise: Regular exercise increases blood flow to the brain.

Prioritize nutrition: Consume a well-balanced diet that includes plenty of vegetables, omega-3s, and antioxidants.

Get quality sleep: 7–9 hours at night.

Manage chronic conditions: Maintain diabetes, hypertension, and cholesterol control.

When to See a Doctor?

If memory issues begin affecting your or a loved one's day-to-day activities, it's time to seek help. Signs include:

• Getting lost in familiar areas
• Having trouble with personal care
• Repeating stories or asking the same questions
• Having trouble managing money or medications

Don't jump to conclusions but don't wait. A timely diagnosis provides for more effective planning, care, and in some instances, treatment which can halt progression.

Aging has its own unique changes, yet not all forgetfulness indicates an urgent issue. Nevertheless, knowledge and initiative make a world of difference. Educate yourself about the signs, pay attention to your body and never be afraid to consult professionals. Caught early, most factors behind memory problems can be solved, allowing you or your loved one the utmost opportunity for a healthy, well-lived life.
