How to recognise the warning signs, understand the difference and know when to seek help.

“Doctor, my mother has started forgetting things. Is it just her age, or could it be the beginning of dementia?”

This is a question many families ask when they notice changes in an older family member.

Perhaps your father asks the same question several times. Your mother forgets where she has kept her glasses. A previously confident family member begins struggling with online banking or forgets a familiar route.

The family may laugh it off initially. Someone might say, “It happens at this age.” Others may become worried and wonder whether dementia has begun.

The truth is that not every memory problem is dementia, but persistent changes in memory and thinking should never be dismissed as normal ageing.

Two conditions that doctors try to distinguish are mild cognitive impairment and early dementia. They can look similar, particularly in the beginning, but the difference matters.

Let us understand why.

What happens to our memory as we grow older?

As we age, we may take a little longer to remember a name or recall where we have kept something. We might occasionally forget an appointment but remember it later.

These changes do not necessarily mean that something is wrong.

However, there is a difference between occasionally forgetting something and repeatedly struggling with things that were previously easy.

For example, forgetting where you parked your car is one thing. Repeatedly getting lost on a familiar route is quite another.

The important question is not simply, “Does this person forget things?”

It is: “Has this person’s memory or thinking changed noticeably from what was normal for them?”

What is mild cognitive impairment?

Mild cognitive impairment, commonly called MCI, means that a person’s memory or other thinking abilities have declined more than we would expect with normal ageing.

The person may have difficulty remembering recent conversations, concentrating, finding words or organising complicated tasks.

Yet, in most cases, they can still manage their everyday activities independently.

Imagine a retired teacher who has started forgetting appointments and needs to write everything down. She may take longer to organise her finances, but she can still manage her bank account and household responsibilities.

She may have MCI, although a proper assessment is needed to determine the cause.

MCI is important because it may be an early sign of a developing brain disorder. However, MCI does not automatically lead to dementia. Some people remain stable for years, and some improve when contributing problems are identified and treated.

What is early dementia?

Dementia is more than forgetfulness. It occurs when a decline in memory or other thinking abilities begins to interfere with a person’s ability to manage everyday life independently.

Consider another example.

A gentleman who has always managed his household finances begins making repeated errors in payments. He forgets to take his medicines, becomes confused while travelling to a familiar place, or can no longer follow the steps involved in preparing a meal he has cooked for years.

His family may initially attribute these changes to age. But if they represent a persistent decline in his abilities, they deserve medical attention.

Memory loss is not always the first symptom. Some people develop difficulties with planning, judgement, language, attention or recognising familiar situations.

Dementia is not an inevitable part of ageing. It can have several causes, including Alzheimer’s disease and vascular disease affecting the brain.

MCI or early dementia: how can we tell the difference?

The difference often becomes clearer when we look at everyday activities.

Everyday situation	What it might suggest
Occasionally forgetting a name but remembering it later	May occur with normal ageing
Frequently forgetting recent conversations but managing daily activities independently	Could be MCI
Repeatedly making mistakes while paying bills or managing medicines	Needs assessment for possible cognitive impairment, including dementia
Getting lost in familiar surroundings or needing increasing help with everyday tasks	A warning sign that requires medical assessment

These are examples, not a way to diagnose someone at home. A doctor must consider the person’s previous abilities, the nature of the changes and their effect on everyday life.

Why is it so important to get the diagnosis right?

This is the most important part of the discussion.

1. Because some memory problems have treatable causes

An older person who becomes forgetful may have a problem with sleep, depression, hearing, medication side effects, thyroid function or vitamin B12 deficiency.

Several of these problems can affect memory and concentration. Some can improve with appropriate treatment.

This does not mean every memory problem is reversible, or that finding one of these conditions rules out dementia. It means we should not assume the worst without investigating.

A proper assessment helps identify what can be treated and what needs further evaluation.

2. Because early dementia can be missed

A person with early dementia may recognise family members, enjoy conversations and remember events from many years ago.

The family may conclude that their memory is perfectly fine.

Meanwhile, they may be struggling with newer information, financial decisions, medicines or finding their way around.

If we look only at whether someone remembers names, we may miss important warning signs.

3. Because the right support can prevent avoidable problems

Someone with MCI may need a diary, reminders, regular follow-up and help organising complicated tasks.

Someone with dementia may need additional support with medicines, money, cooking or travel, depending on their difficulties.

The aim is not to take away independence unnecessarily. It is to help the person remain independent for as long as possible while reducing avoidable risks.

4. Because treatment depends on the cause

There is no single medicine that treats every form of memory loss.

Some people need treatment for an underlying medical problem. Others benefit from managing blood pressure and diabetes, improving sleep, exercising regularly and staying socially active.

People diagnosed with dementia may need additional treatments and support. Selected patients with early Alzheimer’s disease may also be eligible for specialised treatments, depending on their clinical assessment and the availability of these treatments.

Getting the diagnosis right helps the doctor and family decide what is appropriate.

5. Because it gives families time to plan

A diagnosis of dementia can be difficult to accept. But discovering the problem early gives the person and family more time to discuss future wishes, healthcare, finances and support.

It also allows the person to participate in decisions while they can express their preferences clearly.

At the same time, a diagnosis of MCI should not create unnecessary anxiety. Many people with MCI do not progress to dementia, and their future course cannot be predicted with certainty from a single test.

What should you look for at home?

If you are concerned about an older family member, pay attention to changes such as:

• Repeating the same questions or stories much more often than before.
• Forgetting recent conversations or important appointments.
• Making unusual mistakes with money or medicines.
• Getting confused in familiar places.
• Struggling with familiar household tasks.
• Showing new difficulties with judgement, planning or decision-making.

Ask yourself three simple questions:

Is this new? Has the person’s memory or behaviour changed compared with their usual self?

Is it becoming more frequent? Are the problems recurring or getting worse?

Is everyday life being affected? Does the person need more help than before to manage familiar responsibilities?

If the answer raises concern, arrange a medical assessment rather than waiting for the problem to become severe.

What happens during a memory assessment?

A memory assessment is not simply a test in which someone is asked to remember a few words.

The doctor will usually ask when the problem began, whether it is getting worse and how it affects everyday life. With the person’s permission, a family member may be asked to describe the changes they have noticed.

The assessment may include a short memory and thinking test, a review of medicines, a physical examination and selected blood tests. Brain imaging may be advised when appropriate.

Hearing, vision, mood, sleep and educational background can also influence the results.

Sometimes the diagnosis becomes clear at the first assessment. At other times, follow-up visits are needed to understand how the person’s abilities change over time.

One memory-test score alone cannot tell us whether someone has dementia.

Can we do anything to keep our brains healthy?

Yes. Although no lifestyle change can guarantee that dementia will be prevented, looking after overall health is worthwhile.

• Walk regularly and include appropriate strength and balance exercises.
• Keep blood pressure, diabetes and cholesterol under control.
• Stop smoking.
• Get adequate sleep and seek help for persistent sleep problems.
• Stay connected with family and friends.
• Eat a balanced diet.
• Address hearing and vision difficulties.
• Have medicines reviewed regularly, particularly if new memory problems develop.

These steps are useful at every stage of life and remain important even when cognitive difficulties have already appeared.

One important warning: if someone develops sudden confusion over hours or days, do not assume it is dementia. Sudden confusion can indicate an acute illness or another urgent medical problem and requires prompt assessment.

A final word to families

When an older parent begins forgetting things, it is natural to feel worried. It is equally natural to hope that nothing serious is happening.

Neither panic nor ignoring the problem is the right answer.

Mild cognitive impairment and early dementia are different conditions. Identifying the difference helps us recognise treatable problems, understand future risks, protect independence and provide the right support.

You do not need to wait until your loved one forgets familiar faces or can no longer manage daily activities before seeking help.

Sometimes, the most important first step is simply to notice that something has changed.

At Charvaka Clinic, we encourage families to take concerns about memory and thinking seriously, without jumping to conclusions. A comprehensive geriatric assessment can help clarify what is happening and guide the next steps.

If you have noticed persistent changes in an older family member’s memory, thinking or daily activities, consider arranging an assessment.

Early attention may not answer every question immediately, but it can help you make better-informed decisions for someone you care about.
