Can You Develop Dyslexia Later in Life? Signs of Undiagnosed Adult Dyslexia

If you have reached adulthood and suddenly started wondering whether you might be dyslexic, you are definitely on your own.

I assess adults who have spent years, sometimes decades, knowing that certain things seem to require more effort for them than for other people.

They may read perfectly well but need to reread information several times. They might be successful at work but avoid writing in front of other people. They may struggle to remember verbal instructions, lose their place when reading, take much longer over emails or rely heavily on spellcheck.

And this often leads to one very understandable question:

Have I developed dyslexia as an adult?

Can you develop dyslexia later in life?

No. Developmental dyslexia does not suddenly develop in adulthood.

Dyslexia is a neurodevelopmental difference, which means the underlying differences are present from early in development. What can happen is that dyslexia isn't identified until much later in life.

In other words, you haven't suddenly become dyslexic.

You may simply have reached a point where the strategies that helped you cope are no longer enough or you finally have a name for difficulties that have been there for much longer than you realised.

And this is something I see regularly in my work with adults.

Why can dyslexia go unnoticed until adulthood?

There is still a very stereotypical idea of what dyslexia looks like.

People often assume that someone with dyslexia must have struggled significantly at school, been unable to spell or read, or achieved poorly academically.

That simply isn't the case.

Dyslexia doesn't have one particular look.

You can love reading and be dyslexic.

You can have good spelling and be dyslexic.

You can go to university and be dyslexic.

You can have a successful career and be dyslexic.

You can even have spent your entire working life being the person everyone else considers highly capable, while privately wondering why certain tasks take you so much longer.

Intelligence and dyslexia are not the same thing. Bright, capable people can become extremely good at compensating for areas of difficulty.

The problem is that compensation can hide the amount of effort involved.

Why might dyslexia become more obvious as an adult?

This is where people can understandably feel as though their dyslexia has appeared later in life.

Often, it isn't the dyslexia that has changed.

The demands have.

Perhaps you have moved into a more senior role and suddenly have significantly more reports, emails and paperwork to manage.

Perhaps you have started university.

Maybe you've changed career and are having to absorb large amounts of new information quickly.

Or perhaps you've become a parent and started recognising similarities between your child's difficulties and your own experiences at school.

I hear that last one a lot.

A parent begins researching dyslexia because they are concerned about their child and finds themselves thinking:

Hang on. I do that.

Suddenly, experiences from childhood begin to make much more sense.

What can undiagnosed dyslexia look like in adults?

Adult dyslexia can present differently from the stereotypical picture many of us grew up with.

By adulthood, you have had years to develop strategies. You may not even realise you are using them.

Some adults I work with describe:

• needing to read something several times before it sinks in

• reading more slowly than they feel they should

• struggling to get thoughts onto paper despite being able to explain them clearly

• taking much longer than colleagues to write emails or reports

• difficulty remembering verbal information or instructions

• problems organising written information

• avoiding reading aloud

• spelling inconsistently

• finding note-taking difficult while listening

• feeling overwhelmed when given lots of information at once

• knowing exactly what they want to say but struggling to find the right word quickly.

None of these things individually means that someone is dyslexic.

That is important.

A dyslexia assessment doesn't look for one symptom or rely on a checklist. We look at the pattern across a person's abilities, cognitive processing and literacy skills, alongside their developmental and educational history.

But I did well at school. Could I still be dyslexic?

Yes.

This is one of the biggest misconceptions I encounter.

Good grades do not rule out dyslexia.

Neither does going to grammar school, getting a degree, having beautiful handwriting, being articulate or being good at maths.

For some people, academic success has come with an enormous amount of effort.

Perhaps you revised for considerably longer than your friends.

Perhaps you avoided subjects involving lots of writing.

Perhaps you learnt information almost word for word rather than relying on understanding and recall.

Perhaps you became incredibly organised because you knew what happened when you weren't.

Looking at the outcome alone, the grade, degree or career, can mean we completely miss what it took someone to achieve it.

Why wasn't my dyslexia picked up at school?

For many adults, particularly those educated when understanding of dyslexia was much narrower, there simply wasn't the awareness there is today.

If you could read, behaved well and achieved reasonable grades, there may have been little reason for anyone to look more closely.

Some people were labelled "careless", "slow", "lazy", "messy" or told they needed to concentrate more.

Others simply quietly developed their own ways of coping.

That doesn't necessarily mean anybody deliberately missed something. Our understanding of dyslexia has developed considerably, and we now recognise that it is much more complex than reversing letters or being unable to read.

Can dyslexia get worse with age?

The underlying dyslexia hasn't suddenly become worse, but your experience of it can change.

Stress, tiredness, increased workload and changes in your environment can make existing areas of difficulty much more noticeable.

Imagine that you have spent years managing a particular workload successfully using strategies you have developed yourself.

Then the workload doubles.

Suddenly those strategies aren't quite enough.

It can feel as though something has changed in your brain when, in reality, the demands being placed upon it have changed.

That distinction matters.

Is suddenly struggling with reading always dyslexia?

No and this is particularly important if the change really is sudden.

Developmental dyslexia doesn't suddenly appear in adulthood.

If you have previously had no difficulties with reading, writing or language and experience a new or sudden change, you shouldn't simply assume that it is dyslexia. There can be other explanations for changes in cognitive or literacy skills, and these may need to be discussed with an appropriate healthcare professional.

A late diagnosis of dyslexia is very different from the late onset of a new difficulty.

What does an adult dyslexia assessment actually look at?

A diagnostic assessment looks much deeper than whether you can read and spell.

When I assess an adult, I am interested in the whole picture.

That includes your experiences at school, the strategies you have developed, your current difficulties and the things you do particularly well.

The assessment then explores different areas of cognitive processing and literacy to understand whether there is a pattern consistent with dyslexia.

For many adults, this is the part that finally joins the dots.

It isn't simply about getting a label.

It is about understanding why certain things have always required so much effort.

What happens if I am diagnosed with dyslexia as an adult?

For many people, receiving a diagnosis brings clarity.

It can help you understand the way you process information and identify strategies or adjustments that might make everyday tasks easier.

Depending on your circumstances, a diagnostic report may also help inform reasonable adjustments at work or support within higher education.

But I also think there is something else that matters.

You get to understand your strengths as well as your difficulties.

A good assessment shouldn't leave you with a list of everything you cannot do. It should give you a clearer understanding of your individual cognitive and literacy profile and practical recommendations that are actually relevant to your life.

So, can you get dyslexia later in life?

You can discover that you are dyslexic later in life.

You can be diagnosed with dyslexia later in life.

You can reach a stage where dyslexia becomes much more noticeable because the demands of life, education or work have changed.

But developmental dyslexia itself isn't something you suddenly acquire as an adult.

For many people, the signs were there all along.

They just didn't know what they were looking at.

And sometimes it takes seeing those same patterns in your own child, changing jobs, starting university or simply learning more about dyslexia to finally put the pieces together.

If you've spent years thinking, "Why does this seem so much harder for me than it does for everyone else?", it may be worth finding out why.

Wondering whether you could be dyslexic?

I offer diagnostic dyslexia assessments for adults, giving you a detailed understanding of your individual profile, clear answers and practical recommendations for work, education and everyday life.
