Dyslexia is a common learning disability that affects many people from all over the world. It is a condition that has no cure and affects the way a person understands, processes, retains, recalls, and expresses information. While many adults learn to live with their disability, children with dyslexia are often distracted and struggle through school, some without help because their condition has gone undiagnosed. This paper will tell of the different types of dyslexia, symptoms of the condition, how it is diagnosed, effects it has on those suffering with the disability, and statistics regarding this disability.
Types of Dyslexia
There are three distinct types of dyslexia that have been defined. The first is Visual Dyslexia. With this type, the learner struggles with decoding or spelling words because he or she cannot visualize the word. “These learners tend to have good auditory processing skills as well as an understanding of phonics, but they struggle with visual processing, memory synthesis and sequencing of words” (Warren, E.). The classic symptom of letter reversal is common with this type of dyslexia.
The second type of dyslexia is Auditory Dyslexia. These learners have difficulty expressing phonemic awareness. “These learners tend to have good visual processing skills, but they have deficits in auditory processing as well as linking a sound to a visual cue” (Warren, E.).
The third type of dyslexia is Alexic Dyslexia. This type has difficulty with both Visual Dyslexia and Auditory Dyslexia. These learners are affected by a complete loss of reading ability.
Dyslexia can be developmental or it can be acquired. If it is developmental, it is caused by genetic anomalies in the brain. If the condition is acquired, it was caused by brain trauma, either prenatal or later on in life.
Signs, Symptoms, and Diagnosis
One thing that different types of dyslexics have in common is warning signs and symptoms. According to the Davis Dyslexia Association International, of all of the observable warning signs and symptoms, most dyslexic persons will show around ten of the most common symptoms. Those symptoms can and will vary from day to day, or sometimes even faster than that. Davis says, “The most consistent thing about dyslexics is their inconsistency” (Davis, 1992). Early warning signs of dyslexia can be physical, academic, or even simply general in nature, and can affect a person’s social well-being also.
Physical signs of dyslexia are varied. Patients often complain of feeling dizzy and having stomachaches or headaches while reading (Davis, 1992). They often say they are having trouble seeing also, but when taken to an optometrist no vision problems are detected. However, while some dyslexics have excellent eyesight, others have weak depth perception or peripheral vision (Davis, 1992).
Academically, dyslexic students tend to have trouble with reading skills. They do not associate letter sounds with their names, so...
