Dyslexia is a learning disorder that affects a person’s ability to read and interpret words, letters, and other symbols. It is considered a neurodevelopmental disorder and is thought to be caused by a combination of genetic and environmental factors. Symptoms of dyslexia can include difficulty with reading comprehension, difficulty with decoding words, and difficulty with spelling. Dyslexia is most commonly diagnosed in childhood, but it can also be diagnosed in adults.
Dyslexia test
Dyslexia is typically diagnosed through a combination of formal testing and observation. The most common type of test used to diagnose dyslexia is a psychological assessment, which typically includes measures of reading, spelling, and language abilities. Some of the specific tests that may be used to diagnose dyslexia include the Woodcock-Johnson Tests of Achievement, the Kaufman Assessment Battery for Children, and the Stanford-Binet Intelligence Scale.
Other types of assessments that may be used to diagnose dyslexia include:
- Phonological awareness test: This type of test assesses a child’s ability to hear and manipulate individual sounds in words.
- Sight word test: This type of test measures a child’s ability to recognize common words by sight.
- Reading comprehension test: This type of test measures a child’s ability to understand and make sense of what he or she reads.
- Spelling test: This type of test measures a child’s ability to spell words correctly.
It’s important to note that a diagnosis of dyslexia is not made on the basis of a single test or score, but rather on a combination of results from multiple assessments, along with observation of the child’s behavior and performance in the classroom.
What is dyslexia in adults?

Dyslexia is a learning disorder that affects a person’s ability to read and interpret words, letters, and other symbols. It is considered a neurodevelopmental disorder, and while it is most commonly diagnosed in childhood, it can also be diagnosed in adults.
Adults with dyslexia may experience difficulty with reading comprehension, difficulty with decoding words, and difficulty with spelling. They may also have difficulty with tasks that involve reading, such as filling out forms or reading instructions.
Symptoms of dyslexia in adults can include:
- Difficulty with reading comprehension, especially with long or complex texts
- Difficulty with decoding words, sounding out words or recognizing familiar words
- Difficulty with spelling, including common words
- Difficulty with writing, including organizing thoughts, grammar, and punctuation.
- Difficulty with time management, planning, and organization
- Difficulties with math or number-related tasks, such as calculations or following sequences
- Struggles with memory, especially short-term memory
Adults with dyslexia may have gone undiagnosed during childhood and may have developed coping mechanisms to compensate for their difficulties. However, these coping mechanisms can limit their potential and impact their daily life and career. A proper diagnosis by a qualified professional such as a neuropsychologist, educational psychologist, or learning disability specialist, can help them access the support and accommodations they need to succeed.
What is dyslexia in maths?
Dyslexia is a learning disorder that affects a person’s ability to read and interpret words, letters, and other symbols. It is considered a neurodevelopmental disorder, and while it is most commonly associated with difficulties in reading and writing, it can also affect a person’s ability to understand and work with mathematical concepts.
Symptoms of dyslexia in math can include:
- Difficulty with understanding mathematical concepts and operations
- Difficulty with performing mathematical calculations, such as addition, subtraction, multiplication, and division
- Difficulty with understanding mathematical notation, such as fractions or decimals
- Difficulty with understanding and working with mathematical sequences and patterns
- Difficulty with time management and organization of math-related tasks
- Difficulty with memorizing math facts, such as multiplication tables
Adults and children with dyslexia may have difficulty with math due to the way the brain processes information and may have difficulty with tasks that involve visual-spatial processing, such as manipulating numbers or understanding mathematical diagrams.
What causes dyslexia?

The exact causes of dyslexia are not fully understood, but research suggests that it is a neurodevelopmental disorder that is likely caused by a combination of genetic and environmental factors.
Genetics: Studies have shown that dyslexia can run in families and that certain genes may be associated with an increased risk of developing the disorder.
Neurological factors: Research suggests that there may be differences in the way the brain of an individual with dyslexia processes and interprets visual and auditory information. Studies have shown that certain areas of the brain may be smaller or function differently in individuals with dyslexia, particularly in the areas related to language processing and phonological awareness.
Environmental factors: Environmental factors such as exposure to toxins, premature birth, and low birth weight may also play a role in the development of dyslexia.
Dyslexia symptoms
Dyslexia is a learning disorder that affects a person’s ability to read and interpret words, letters, and other symbols. Symptoms of dyslexia can vary depending on the individual and can include:
- Difficulty with decoding words, sounding out words, or recognizing familiar words
- Difficulty with reading comprehension, especially with long or complex texts
- Difficulty with spelling, including common words
- Slow reading speed, and difficulty with fluency
- Difficulty with writing, including organizing thoughts, grammar, and punctuation
- Difficulties with math or number-related tasks, such as calculations or following sequences
- Difficulty with memory, especially short-term memory
- Struggles with time management, planning, and organization
- Difficulty with phonological awareness, such as the ability to break words into individual sounds
- Difficulty with learning new vocabulary
- Difficulty with understanding jokes, idioms, and sarcasm
Types of dyslexia
There are different types of dyslexia, and the type and severity of symptoms can vary depending on the individual. Some common types of dyslexia include:
- Phonological dyslexia: This type of dyslexia is characterized by difficulty with phonological processing, which is the ability to process and manipulate individual sounds within words. People with phonological dyslexia may have difficulty with decoding words, sounding out words, and recognizing familiar words.
- Surface dyslexia: This type of dyslexia is characterized by difficulty with recognizing and reading irregular words, despite having intact phonological processing skills. People with surface dyslexia may have difficulty with spelling and reading words that have unusual spellings, such as “yacht” or “colonel”.
- Rapid naming dyslexia: This type of dyslexia is characterized by difficulty with the rapid naming of letters, words, colors, and objects. This can lead to difficulty with reading fluency and comprehension
- Math dyslexia: This type of dyslexia is characterized by difficulty with math-related tasks, such as understanding mathematical concepts, performing calculations, and understanding mathematical notation.
- Attentional dyslexia: This type of dyslexia is characterized by difficulty in paying attention to the written language and is often associated with ADHD or attention-deficit disorder
Dyslexia examples
Dyslexia is a learning disorder that affects a person’s ability to read and interpret words, letters, and other symbols. Examples of how dyslexia may manifest in an individual’s reading and writing abilities include:
- Difficulty with decoding words: An individual with dyslexia may struggle with sounding out unfamiliar words, and instead may try to guess the word based on the first letter or the overall shape of the word.
- Difficulty with reading comprehension: An individual with dyslexia may have difficulty understanding what they read, and may have difficulty following a story or a passage of text.
- Difficulty with spelling: An individual with dyslexia may have difficulty spelling even common words and may struggle with spelling rules and patterns.
- Slow reading speed: An individual with dyslexia may read slowly and have difficulty with reading fluency, which can affect comprehension.
- Difficulty with writing: An individual with dyslexia may have difficulty organizing thoughts, constructing sentences, and writing coherently.
- Difficulty with math-related tasks: An individual with dyslexia may have difficulty understanding mathematical concepts, performing calculations, and understanding mathematical notation.
- Difficulty with phonological awareness: An individual with dyslexia may have difficulty breaking words into individual sounds and may struggle with identifying and manipulating sounds in words.
