Dyslexia

Dyslexia is a brain-based type of learning disability that specifically impairs a person's ability to read. These individuals typically read at levels significantly lower than expected despite having normal intelligence. Although the disorder varies from person to person, common characteristics among people with dyslexia are difficulties with phonological processing (the manipulation of sounds), spelling, and/or rapid visual-verbal responding. In individuals with adult onset of dyslexia, it usually occurs as a result of brain injury or in the context of dementia; this contrasts with individuals with dyslexia who simply were never identified as children or adolescents.  

Dyslexic people are highly creative, intuitive, and excel at three-dimensional problem solving and hands-on learning. Our visual and holistic learning style means that we learn best through the creative process, with methods that focus on mastery of the meanings of words and symbols. The true gift of dyslexia is the gift of mastery. When we use learning methods that fit our thinking style, we can excel in academics and read and write efficiently. The sooner dyslexia is treated, the more favorable the outcome; however, it is never too late for people with dyslexia to learn to improve their language skills.

There are several types of dyslexia that can affect the child's ability to spell as well as read.

1. Trauma dyslexia usually occurs after some form of brain trauma or injury to the area of the brain that controls reading and writing. It is rarely seen in today's school-age population.

2. Primary dyslexia, this type of dyslexia is a dysfunction of, rather than damage to, the left side of the brain (cerebral cortex) and does not change with age. Individuals with this type are rarely able to read above a fourth-grade level and may struggle with reading, spelling, and writing as adults. Primary dyslexia is passed in family lines through their genes (hereditary). It is found more often in boys than in girls.

3. Secondary or developmental dyslexia is felt to be caused by hormonal development during the early stages of fetal development. Developmental dyslexia diminishes as the child matures. It is also more common in boys.

Dyslexia may affect several different functions. Visual dyslexia is characterized by number and letter reversals and the inability to write symbols in the correct sequence. Auditory dyslexia involves difficulty with sounds of letters or groups of letters. The sounds are perceived as jumbled or not heard correctly. “Dysgraphia” refers to the child's difficulty holding and controlling a pencil so that the correct markings can be made on the paper.

The main focus of treatment should be on the specific learning problems of affected individuals. The usual course is to modify teaching methods and the educational environment to meet the specific needs of the individual with dyslexia. There is no quick fix or silver bullet for dyslexia. It can take from 1 to 3 years to get a dyslexic child reading and spelling at grade level, depending upon their level of severity, the frequency of their tutoring or intervention, and other issues.
