How to Recognise Dyslexia Symptoms by Age


Dyslexia is a learning disorder that affects both children and adults. Its symptoms are different with age, and severity can vary as well. Generally, people with dyslexia have difficulty breaking down words into simple sounds. They struggle to learn how sounds relate to letters and words, which leads to slow reading and poor reading comprehension.

Dyslexia is often known as a reading disability. It’s most often identified in childhood when reading problems first become apparent. But dyslexia can go undiagnosed for years or even decades.

Dyslexia is not connected with intelligence. It is a neurobiological disorder that affects the parts of your brain involved in language processing.

Despite its biological basis, dyslexia can’t be diagnosed with a simple blood test or brain scan. When doctors make a diagnosis, they consider the results of a series of reading tests along with the symptoms reported by the person, their parents, or their teachers.

Keep reading to learn how dyslexia symptoms can vary with age, plus what symptoms to look out for and when.

The preschool years

The earliest signs of dyslexia emerge around 1 to 2 years of age when children first learn to make sounds. Children who don’t say their first words until 15 months of age or their first phrases until 2 years of age have a higher risk of developing dyslexia.

However, not all people with speech delays develop dyslexia, and not all people with dyslexia have speech delays as children. A speech delay is just a cue for parents to pay attention to language development.

Children from families with a history of reading difficulties should also be monitored closely for dyslexia.

Other dyslexia warning signs that arise before age 5 years include:

  • having problems learning and remembering the names of letters in the alphabet
  • having difficulty learning the words to common nursery rhymes
  • being unable to recognize the letters of their own name
  • mispronouncing familiar words or using baby talk
  • being unable to recognize rhyming patterns

Kindergarten and first grade

Around age 5 or 6 years, when kids begin learning to read, dyslexia symptoms become more apparent. Children who are at risk of reading disabilities can be identified in kindergarten. There is no standardized test for dyslexia, so your child’s doctor will work with you to evaluate their symptoms.

Signs that your kindergartener or first grader may be at risk include:

  • not understanding that words break apart into sounds
  • making reading errors that aren’t connected to the sounds of the letters on the page
  • having a history of parents or siblings with reading problems
  • complaining about how hard reading is
  • not wanting to go to school
  • showing problems with speaking and pronunciation
  • having trouble sounding out basic words like “cat” or “map”
  • not associating letters with sounds (for example, that “p” sounds like “paa”)

Early intervention programs usually focus on phonological (word sound) awareness, vocabulary, and reading strategies.

Second through eighth grade

Many teachers are not trained to recognize dyslexia. Children who are intelligent and participate fully in class often slip through the cracks because they are good at hiding their reading trouble. By the time your child reaches middle school, they may have fallen behind in reading, writing, and spelling.

Signs of dyslexia in grade school and middle school include:

  • being very slow in learning to read
  • reading slowly and awkwardly
  • having difficulty with new words and sounding them out
  • disliking or avoiding reading out loud
  • using vague and inexact vocabulary, like “stuff” and “things”
  • hesitating while finding words and answering questions
  • using a lot of “umms” in conversation
  • mispronouncing words that are long, unknown, or complicated
  • confusing words that sound alike
  • having trouble remembering details, such as names and dates
  • having messy handwriting

Young adulthood: High school and college years

  • pausing and hesitating often while speaking
  • using a lot of “umms”
  • using vague and imprecise language
  • pronouncing names and places wrong frequently
  • having difficulty remembering names
  • confusing like-sounding names
  • missing quick responses in conversation
  • having limited spoken vocabulary
  • having difficulty with multiple-choice tests
  • considering themselves stupid despite good grades

Dyslexia in adults

Various estimates suggest that as many as 5 to 10 percentTrusted Source of the population may have dyslexia. It’s typically diagnosed in childhood, but some people are never diagnosed. If you’ve always had trouble reading, there’s a good chance you could have dyslexia.

Craig has shown me support and helped make my course work manageable. I feel that I have been able to turn to Craig with any question or doubt and have received nothing but clarity and guidance.
