Dementia Myths Debunked: What’s Delaying Diagnosis

2 May

When someone forgets where they’ve put their keys or struggles to recall a name, it’s easy to brush it off as “just getting older.”

But sometimes, it’s not.

One of the biggest challenges with dementia isn’t just the condition itself — it’s the misunderstandings that surround it.

These myths can delay people from seeking help, sometimes for years. And that delay matters more than most people realise.

Research suggests that the gap between first symptoms and a formal dementia diagnosis is often over three years. That’s three years without clarity, support, or access to the right care.

In this article, we’re breaking down some of the most common myths — and why letting go of them could make a real difference.

Why Dementia Myths Are So Harmful

Myths don’t just create confusion — they create hesitation.

They make people second-guess what they’re noticing.
They delay conversations with doctors.
They push support further out of reach.

And the reality is, earlier diagnosis can open doors:

Access to treatment and support
Time to plan ahead
More opportunities to maintain independence
Better understanding for families

Let’s look at the myths that often stand in the way.

Myth 1: “Dementia is just a normal part of ageing”

This is one of the most common — and most damaging — beliefs.

Yes, some memory changes can happen as we get older. But dementia is different.

What’s the difference?

Normal ageing: occasionally forgetting names or misplacing items, but remembering later
Dementia: memory loss and confusion that interfere with daily life

For example:

Struggling to follow conversations
Getting lost in familiar places
Repeating the same questions frequently
Difficulty completing everyday tasks

Why this myth is harmful:
When people assume it’s “just ageing,” they delay seeking help — often until symptoms become more severe.

Myth 2: “Only very old people get dementia”

While dementia is more common in older adults, it doesn’t only affect people in their 70s, 80s, or beyond.

The reality

Younger-onset dementia can affect people in their:

In these cases, symptoms are often overlooked or misdiagnosed.

Changes in behaviour, mood, or performance at work might be attributed to stress, burnout, or mental health — rather than something neurological.

Why this myth is harmful:

People don’t seek help early
Families may not recognise the signs
Diagnosis is delayed, affecting careers, relationships, and future planning

Myth 3: “Dementia means Alzheimer’s”

Alzheimer’s is the most well-known form of dementia — but it’s not the only one.

Dementia is an umbrella term

It includes several different conditions, such as:

Alzheimer’s disease
Vascular dementia
Lewy body dementia
Frontotemporal dementia

Each type has different causes, symptoms, and progression patterns.

Why this matters

When dementia is misunderstood as a single condition:

The wrong assumptions may be made about symptoms
Support may not be tailored correctly
Families may struggle to understand what’s happening

Getting the right diagnosis helps guide the right support and care.

What Caregivers Should Watch For

If you’re supporting someone and something doesn’t feel quite right, trust that instinct.

Look out for:

Increasing confusion or disorientation
Changes in personality or behaviour
Difficulty with everyday tasks
Withdrawal from social situations
Repetition or memory gaps

You don’t need to have all the answers — just noticing patterns is enough to start the conversation.

What to Do If You’re Concerned

If you’re worried about yourself or someone else:

1. Don’t wait

It’s always better to check early than to delay.

2. Speak to a GP

They can begin the assessment process or refer you to a specialist.

3. Keep a record

Note changes in behaviour, memory, and daily functioning — this helps during appointments.

4. Involve family where possible

Having support makes the process easier to manage.

A Final Thought

Dementia doesn’t always look the way people expect it to.

And that’s exactly why these myths are so dangerous — they stop people from recognising what’s right in front of them.

Challenging these beliefs isn’t about creating fear.
It’s about creating awareness, clarity, and earlier support.

Because the sooner you understand what’s happening,
the sooner you can take steps to manage it — together.
