No, dyslexia and autism are distinct neurodevelopmental conditions, but they often co-occur, meaning someone can have both, as they share some underlying processing difficulties and language challenges, though dyslexia primarily impacts reading/language (e.g., decoding words) while autism centers on social communication/interaction and repetitive behaviors. While separate diagnoses, there's a notable overlap, with many individuals with autism also having dyslexia, and vice versa, suggesting shared genetic or processing roots, but one doesn't cause the other.
Yes. Many people with dyslexia can learn to read faster--often dramatically--when instruction targets the specific phonological, orthographic, and cognitive processes that underlie reading.
Dyslexia and ADHD often occur together in people and they share many genes in common – links which make them distinct from developmental and mental health diagnoses such as autism, bipolar disorder and schizophrenia, a study shows.
The merging of three separate learning disorders into one diagnostic category under Specific Learning Disorder (SLD) in the DSM-5 required three different specifiers to identify the area(s) of academic weakness: With impairment in reading (dyslexia) With impairment in written expression (dysgraphia)
Dyslexia does not involve repetitive behaviors or restricted interests as a defining feature. It is primarily characterized by difficulties in language processing and academic tasks. Autism spectrum disorder often involves repetitive behaviors, such as hand-flapping, rocking, or engaging in rigid routines.
Five key characteristics of dyslexia include difficulty with accurate and fluent reading, problems with spelling and writing, trouble retrieving words or mixing up sounds, avoiding reading/writing tasks, and challenges with sequencing (like days of the week or times tables), often stemming from difficulties with phonological processing (connecting sounds to letters).
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
The key to success in managing dyslexia is understanding that it is an impairment in brain functioning, not a learning disability. Dr. Raffle performs an evaluation to help identify specific areas of brain impairment that results in reading problems.
While there are various ways to classify dyslexia, four commonly discussed types focus on specific reading challenges: Phonological Dyslexia (sound-letter connection), Surface Dyslexia (whole-word recognition), Rapid Naming Dyslexia (speedy identification), and Double Deficit Dyslexia (a combination of phonological and rapid naming issues). These types highlight different core difficulties, from sounding out words to recognizing them quickly, and help guide tailored support strategies.
A: While both autism and dyslexia are neurodevelopmental disorders, they are distinct conditions with different core symptoms. There is no direct causal connection between autism and dyslexia, but they may co-occur in some individuals.
Dyslexia Has No Link to Intelligence
In fact, many students with dyslexia have average to above-average IQs. They are often curious, insightful, and deeply engaged with learning, especially when it comes to rich stories, interesting topics, or verbal conversations. But dyslexia isn't about intelligence.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
According to UMHS, the following conditions can present similar symptoms and difficulties to dyslexia:
Both mothers and fathers can pass dyslexia on to their children if either parent has it. There is roughly a 50% – 60% chance of a child developing dyslexia if one of their parents has it.
5 things not to say to your child about dyslexia
Early help is vital to reduce the chance of loss of confidence and low self-esteem. A child can only be diagnosed with dyslexia through a Diagnostic Assessment but these are usually only carried out from 7 years old.
Dyslexia is not a disease. It's a condition a person is born with, and it often runs in families. People with dyslexia are not stupid or lazy. Most have average or above-average intelligence, and they work very hard to overcome their reading problems.

While the exact reasons are not yet clear, changes in how the disorder is defined, increases in screening, and more awareness certainly contribute to this increase. If you have any concerns about your child's development, speak to a healthcare professional about diagnostic tests.
Understanding the 6 stages of an autism meltdown can help parents, caregivers, and educators respond with empathy and support.
Q: Is autism genetic from mother or father? A: Autism can be inherited from either parent, as it often involves a combination of genetic factors. No single parent is solely responsible, and it typically results from a complex interaction of genes from both sides.
Confusion between left and right. Struggling with tasks like tying shoes. Mixing up sounds and syllables in long words. Trouble memorizing important things like their address or phone number.
Dyslexia does not worsen over time. However, the demands of adult life—more complex reading, multitasking, or workplace expectations—can make its effects more noticeable. With continued support, individuals often learn to manage their challenges and build on their strengths.
While no single test can adequately capture that whole, complex picture, the Grade-Level Word Reading Assessment (SDQA) in combination with the Dyslexia Z-ScreenerTM has proven to be a quick and reliable way to identify students who are struggling with reading words.
