Levels of dyslexia are categorized by severity as mild, moderate, or severe, reflecting the degree of difficulty and need for intervention, not specific test scores, and are determined clinically based on how much support is required for skill improvement, with co-occurring conditions like ADHD often influencing the classification. Beyond severity, dyslexia also has different types, like phonological (sound-letter link issues) or surface dyslexia (sight word recognition), and causes, such as developmental (from birth) or acquired (due to brain injury).
There are four types of dyslexia in common those are; Phonological dyslexia, surface dyslexia, rapid naming deficit, and double deficit dyslexia.
Dyslexia also has levels of severity: Mild: Difficulties are there, but you can compensate or work around them with the right accommodations or support. Moderate: Difficulties are significant enough that you need specialized instructions and help. You may also need specific interventions or accommodations.
A person with double deficit dyslexia struggles with two aspects of reading. These two aspects often include naming speed and identifying the sounds in words. This type of dyslexia is a combination of rapid naming and phonological and is not uncommon; however, it is largely regarded as the most severe type of dyslexia.
Babies and preschool
Even though most people do not read in preschool, children can demonstrate symptoms of dyslexia by the age of 3 years, or even earlier. All children learn how to talk in their own way and at their own pace. However, a delay in starting to speak can be an early sign of dyslexia.
General signs to look for are:
According to UMHS, the following conditions can present similar symptoms and difficulties to dyslexia: Attention Deficit Hyperactivity Disorder (ADHD) Executive Dysfunction. Memory Impairments.
Famous actors like Johnny Depp, Keira Knightly and Orlando Bloom all have dyslexia. Pablo Picasso's teachers described him as “having difficulty differentiating the orientation of letters”.
No, dyslexia is not a form of ADHD; they are two separate, distinct neurodevelopmental conditions, but they frequently co-occur because they share some overlapping symptoms like inattention, memory issues, and executive function challenges, making accurate diagnosis important for proper treatment. ADHD is a neurobehavioral disorder affecting focus, hyperactivity, and impulsivity, while dyslexia is a specific learning disability impacting reading, spelling, and language processing.
5 things not to say to your child about dyslexia
Three dimensional thinking and making connections
Many people with dyslexia demonstrate better skills at manipulating 3D objects in their mind. Many of the world's top architects and fashion designers have dyslexia.
Bill Gates, one of the richest people in the world didn't let his dyslexia hold him back.
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.
Students with dyslexia usually experience difficulties with other language skills such as spelling, writing, and pronouncing words. Dyslexia affects individuals throughout their lives; however, its impact can change at different stages in a person's life.
When people with dyslexia see text on a page, a whole range of different phenomena can occur. For example, some people may experience letters appearing to jump around, while others might confuse similar-looking letters that are close in appearance. It can vary greatly from person to person.
Complications. Dyslexia can lead to several problems, including: Trouble learning. Because reading is a skill basic to most other school subjects, a child with dyslexia is at a disadvantage in most classes and may have trouble keeping up with peers.
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 ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
When a child struggles with reading, writing, or staying focused in the classroom, many parents and teachers are quick to suspect a learning disorder such as ADHD or dyslexia. While these diagnoses are valid and prevalent, one often-overlooked issue can mimic many of the same symptoms: poor vision.
Ryan Gosling has accumulated praise for movies like The Notebook, La La Land, and Barbie. However, behind this fame, his life's story was full of bravery. The Hollywood hunk faced dyslexia and Adhd as a kid. School was difficult, and bullying made it worse.
Actress Jennifer Aniston has publicly shared that she was diagnosed with dyslexia in her 20s, a diagnosis that explained lifelong struggles with reading, writing, and retaining information, leading her to believe she wasn't smart until discovering the learning disorder. She discovered this during an eye exam, where she realized her eyes jumped words when reading, and the diagnosis helped her understand past difficulties, transforming her self-perception.
Some of these successful entrepreneurs, such as Richard Branson and Charles Schwab, credit their success to dyslexia as one of the contributing factors that lead to the development of their innovative thinking and their remarkable success.
Dyslexia is not a physical problem with the eyes but a neurological difficulty with the brain. Many of the most common difficulties are caused by the way the brain recalls and works with letters and sounds, called phonological processing.
in the Simple View of Writing
For example, the writing of students with dyslexia may suffer from one or more of the following issues: a high percentage of misspelled words, difficult-to-read hand- writing, poor organization, a lack of fully developed ideas, and/or a lack of diverse vocabulary.
It was Kussmaul who first identified the kind of difficulties Berlin described, in 1877, entitling them Wortblindheit (word-blindness). (Berlin coined 'dyslexia' to bring the diagnosis in line with contemporary international medical literature, which elsewhere described the similar conditions of alexia and paralexia.)
