Dyslexia

Individuals with dyslexia face trouble learning to read out loud and spell. According to the DSM5, dyslexia is a type of neurological disease. Neurodevelopmental diseases are genetic conditions that last a lifetime and show symptoms early in life. Research on dyslexia was based for a long time on the idea that it was a specific learning disability. By this, we meant that the disability could not be explained by clear causes like sensory issues or general learning challenges (low IQ). Then, because it wasn’t possible to tell the difference between how well kids with dyslexia and kids with more general learning problems read and use sounds, this way of defining “discrepancy” lost favor (Snowling et al., 2020).

Given that they have problems with the phonological part of language, people with dyslexia have trouble connecting spoken and written language. Decoding words correctly and quickly can make it harder to understand what you read and build your knowledge (Kim et al., 2012). Spelling problems can make it hard to compose written work properly. Dyslexia can make people do badly in school, feel bad about themselves, and lose drive. This doesn’t mean someone is stupid, lazy, or has bad eyesight; it happens to people of all brain levels (Berninger et al., 2013).

At first, the word dyslexia was called “word blindness” (Campbell, 2011). It comes from the Greek words for “days” (lexi, from lexicon) and “ia,” which means “impaired.” People with developmental dyslexia have trouble reading, decoding, and writing words at the word level; writing seems to be the most chronic problem (Berninger et al., 2008). The Working Definition of Dyslexia under the Individuals with Disabilities Education Act (IDEA) is a “specific learning disability” (Roitsch & Watson, 2019). Developmental dyslexia is one important example of a learning disability that has social and emotional effects that aren’t thought to be the main symptoms of the disorder. These problems can still be there or even get worse as an adult (Livingston et al., 2018). Therefore, early diagnosis and treatment of the disorder are essential to ensure the prevention of adverse consequences. Given next are the diagnostic features of dyslexia.

Diagnostic Features

The following are prominent features of dyslexia (Roitsch & Watson, 2019):

1. Trouble developing sound awareness and thinking skills.
2. Trouble correctly interpreting nonsense or things you need to know.
3. Trouble reading single words on their own.
4. Oral reading is wrong and hard to do.
5. Not being able to read quickly.
6. Different levels of learning the names of letters and the sounds they make.
7. Trouble learning how to spell.
8. Trouble finding words and naming things quickly.
9. Having different levels of trouble with different parts of writing.
10. Different levels of trouble understanding what they read.

Most of the time, kids in preschool and early elementary school who have dyslexia have trouble learning to talk, learn sounds and letters, colors and numbers, write, use their fine motor skills, and recognize sight words. The fact that these kids have trouble with pronunciation is often a sign that they might have trouble reading later on. Older kids with dyslexia may have bad handwriting, trouble learning foreign languages, issues with ordering language, trouble remembering things, spelling mistakes, and ongoing reading, writing, and math problems (IDA, 2019). Spelling and remembering words with more than one letter can be noticed in written language. Comprehension and understanding may be hard in reading skills, and reading skills that are slow and often wrong may be noticed. People who have dyslexia often have trouble phonologically coding words, which means they have trouble knowing how words sound and what they mean (Snowling, 2019, as quoted in Roitsch & Watson, 2019).

Cognitively, people with dyslexia have trouble recognizing hidden shapes (Martinelli & Schembri, 2014), shifting their attention, and having problems with parts of their working memory that deal with spoken and written language (the phonological loop) (Berninger et al., 2015). Working memory is one of the most common symptoms of dyslexia that people name. When someone with dyslexia has trouble with working memory, they have trouble temporarily storing knowledge while doing other cognitive tasks at the same time (Baddeley, 1992, as cited in Roitsch & Watson, 2019). Teenagers’ ability to read quickly is affected by their language knowledge, which is linked to their verbal working memory (Shaywitz et al., 2008). Language experts, interventionists, and diagnosticians face new problems with a group of people that consists of those who are talented and also have dyslexia. People who are “twice exceptional” often do better than their regular peers on tasks that test their speech, working memory, and language skills, but they take longer to learn phonological awareness and how to name things quickly. Additionally, these individuals show very high verbal reasoning skills. However, it can be hard for teachers and parents to diagnose dyslexia in these individuals because their abilities often hide the effects of dyslexia on spoken and written language tasks as well as standardized tests (van Viersen et al., 2016), while the core deficits associated with dyslexia remain (Nielson et al., 2016). The same is true for adults with dyslexia: their symptoms are often less obvious because they have learned how to deal with the condition and the problems that come with it. Mental problems like not understanding sounds and naming things quickly, as well as problems with working memory and written language, may still be present (Kilpatrick, 2015), along with other thinking and reading problems (Chung et al., 2011).

Conclusion

Dyslexia is a learning disorder that makes it hard to read, write, spell, and even talk. The International Dyslexia Association says that about 10% of people have dyslexia. Individuals with dyslexia cannot meet school standards because of their disabilities, which makes them feel overwhelmed and unimportant. With a world prevalence of at least 10%, a lot of students with dyslexia don’t get identified or get help for their symptoms. However, 90% of dyslexic children can be taught in normal classrooms with other kids their age if they get help early enough. It’s concerning that dyslexia was found in a large portion of the study sample. This highlights the need for more research and programs, such as campaigns to raise awareness among teachers, parents, and school officials. It’s also important to find children who haven’t been diagnosed with dyslexia yet and give them the right help as soon as possible (Sunil et al., 2023). The features mentioned above can help identify and diagnose dyslexia.
