Dyslexia in Adult Life

Can reading trouble last into adult life?

Reading and spelling trouble can last into adult life. The International Dyslexia Association (IDA) wrote a new definition in 2025. The IDA's definition says the trouble lasts even with teaching that works for other children their age. It does not say for how long.

One study followed a group of poor readers for 30 years, into mid-life (Maughan and colleagues, 2009). The study took place on the Isle of Wight, in the UK. At mid-life, their spelling remained well behind. That study measured spelling, not reading or how life went. It followed one group from one place, from the 1960s and 1970s. Everyone in it went to school. So it does not show what happens without teaching. In that study, more reading and writing as a teen and young adult went with better adult spelling.

What we know about teaching adults

"Although identification and targeted instruction are important at any age, language and literacy support before and during the early years of education is particularly effective," says the International Dyslexia Association's 2025 definition.

Adults can make gains when they are taught. One review gathered studies of reading help for adults with dyslexia (Vender, Melloni and Delfitto, 2022). It found eight. It says research on adults is still sparse. Its authors wrote that literacy training can bring gains for adults with dyslexia too. They also wrote that more research is needed.

One small study taught Italian adults with dyslexia (Vender and Delfitto, 2025). It used a program its authors made. The adults who were taught made gains in reading and spelling. Italian is spelled more regularly than English. The groups were small, and were not split at random. So the result may not apply to adults who read English.

If you are an adult who finds reading hard

Need support at college or at work? Ask if the college or employer has a disability services office.

We hold no source on how dyslexia is identified in adults.

Our position is that reading lost after a brain injury goes to a doctor.

Looking ahead for your child

No study we hold predicts how far one child's reading will go with teaching. A diagnosis describes where a child is today. It does not predict where they will be after a year of the right kind of practice.

Reading improves with reading instruction. In our view, keep your child reading and writing at home too.

If your child finds reading or spelling hard, here is what to work on. Find which job of reading is going wrong, and work on that one. The exception is a skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.

Have hearing and vision checked too. A child who cannot hear well needs that found. So does a child who cannot see the print clearly.

When to ask for help

Each of these is a reason to ask for help on its own.

• Little change, even with steady practice and good teaching.
• Reading well below what school expects.
• A teacher who raises a concern about reading.
• Extreme upset about reading.
• Complete avoidance of reading.
• Hopelessness about learning.
• Sadness or worry that lasts.
• Significant delays in speech, language or motor development.
• A skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.

If no skill has gone, start with the teacher. Say what you are seeing at home, and what you have tried. Beyond the teacher, the right person depends on what it turns out to be about. If the work is too hard, someone who works on that school skill. If worry or mood is the thing, someone who works with children's mental health. In our view, delays in speech, language or movement are worth raising with your child's doctor. In our view, if you are worried enough to ask, a professional evaluation is worth asking about.

Any talk of hurting themselves is a same-day call to your doctor or a crisis line.
