Dementia vs Old Age: Knowing What is Natural and What Could Be Dementia

It’s natural to become more forgetful or slower with age. But how do you know if it’s part of the normal ageing process, or something more serious like dementia? Many families struggle with this question when a loved one starts to change in ways that seem unfamiliar or worrying.

While ageing affects everyone differently, there are some clear distinctions between typical age-related changes and symptoms that may indicate dementia. Understanding those differences can help you feel more confident about what to look out for and when to seek support.

In this guide, we explore what’s normal with ageing, what signs could point to dementia and how to get the right help if you’re concerned about a loved one.

What’s normal with ageing?

As we get older, it’s common to experience changes in memory, focus and physical health. These changes are usually mild and don’t interfere with day-to-day life. Here are some examples of what’s typically considered part of the natural ageing process:

Occasional forgetfulness – Misplacing your keys or forgetting why you walked into a room
Slower recall – Taking longer to remember names, dates or recent conversations
Reduced attention span – Finding it harder to multitask or stay focused for long periods
Mild word-finding difficulties – Momentarily struggling to recall a word, but remembering it shortly after
Mood shifts – Feeling a bit more irritable or anxious, especially during periods of change or stress

These changes tend to be infrequent and manageable. Crucially, they don’t stop someone from living independently or engaging with the people and activities they enjoy.

What are the early signs of dementia?

Dementia is a progressive condition that affects memory, thinking, behaviour and the ability to perform everyday tasks. The symptoms go beyond what’s expected with ageing and tend to worsen over time. While symptoms can vary by person and dementia type, early warning signs might include:

Frequent memory loss – Forgetting recent events, conversations or appointments repeatedly
Difficulty completing familiar tasks – Struggling with daily routines like cooking, managing finances or getting dressed
Confusion about time or place – Getting lost in familiar places or not knowing what day or season it is
Poor judgment – Making unusual decisions, such as dressing inappropriately for the weather or giving away large sums of money
Language problems – Repeating themselves often or having trouble following or joining in conversations
Changes in personality or behaviour – Becoming unusually suspicious, withdrawn, anxious or upset
Losing interest in activities – A noticeable drop in motivation, hobbies or socialising

Unlike natural ageing, these signs can start to impact a person’s independence, relationships and overall well-being. If several of these symptoms appear and continue to worsen, it’s important to seek advice from a healthcare professional.

When to seek support

If you’ve noticed a change in a loved one’s memory, thinking or behaviour, and those changes are becoming more frequent or disruptive, it’s worth having a conversation with their GP. An early assessment can help rule out other causes, such as stress, depression or infections, which can sometimes mimic dementia symptoms.

In some cases, early support and intervention can help manage symptoms, slow progression and improve quality of life. Knowing the cause allows you to plan ahead and get the right care in place, whether that’s occasional home support or full-time dementia care.

If you’re starting to explore care options, our dementia care at home guide offers useful information on how we support individuals to remain safe and independent in their familiar surroundings.

Understanding different types of dementia

There are several forms of dementia, each with their own pattern of symptoms. The most common include:

Alzheimer’s disease – The most common type of dementia, marked by memory loss, confusion and difficulty with problem-solving
Vascular dementia – Often caused by reduced blood flow to the brain, leading to problems with planning, focus and mood
Lewy body dementia – Associated with visual hallucinations, sleep disturbances and changes in movement or attention
Frontotemporal dementia (FTD) – Typically affects personality, behaviour and language more than memory, and often occurs at a younger age

Recognising the specific type of dementia can help tailor care to the individual’s needs.

How a dementia diagnosis can help

A diagnosis may feel daunting at first, but it can also bring clarity and relief. It provides a better understanding of the changes you’ve been seeing and opens the door to helpful support and resources. You can:

Access memory clinics and specialist care
Receive guidance on managing symptoms and behaviours
Plan ahead with legal and financial decisions
Learn ways to support communication and independence
Explore tailored care options, including support at home

Early action empowers families to make informed choices and helps people with dementia maintain their dignity and quality of life for longer.

Practical steps you can take

If you’re worried about someone you care for, here are some things you can do:

Start a conversation – Gently express your concerns and listen to how they’re feeling. Try not to be confrontational.
Keep a diary – Track behaviours, memory lapses or changes in routine to help build a clear picture.
Visit the GP together – Offer to go with them to the doctor and help communicate what you’ve observed.
Educate yourself – Understanding dementia helps you respond with patience, empathy and confidence.
Explore support – Whether it’s community resources, dementia-friendly activities or in-home care, help is available.
