What is dyslexia?
Dyslexia is a lifelong disorder associated with reading, spelling, pronouncing, and/or writing. It however does not determine the intelligence of the individual.
The U.S National Institute of Health
define dyslexia specifically as a learning disorder in a context of
normal intelligence. Also called the ‘reading disorder,’ affected
individuals might require special teaching techniques to understand
complex ideas, depending on the degree of the disease.
According to the US Department of Education, more than 2 million students ages 3-21 have learning disabilities.
Dyslexic
individuals are very creative and likely to be successful. Some famous
people who are known to have dyslexia includes director Steven Spielberg, Albert Einstein, investor Charles Schwab, actress Whoopi Goldberg
amongst others. It is unclear whether such creativity comes from
thinking outside the box or from having a brain that is “wired” a bit
differently.
What causes dyslexia?
Researchers
are yet to determine the exact cause of Dyslexia but the causes of the
reading disorder has been associated with hereditary genes, brain
activity and brain anatomy.
What are the types of dyslexia?
There
are various types of dyslexia, but the major types includes primary
dyslexia, secondary dyslexia trauma dyslexia, visual dyslexia, auditory
dyslexia, and dysgraphia.
Primary dyslexia:
this is the most common type of dyslexia. This has been researched to
be hereditary. It is defined as the dysfunction of the left side of the
brain.
Secondary dyslexia: This is associated with problem with brain development during the early stages of fetal development
Trauma dyslexia: This type of dyslexia is caused by brain trauma in areas of the brain that controls reading and writing.
Visual dyslexia: This is a condition in which the brain does not, properly interpret visual signals.
Auditory dyslexia: This is a condition in which there are problems with the part of the brain processing sounds and speech.
Dysgraphia: This refers to a child’s difficulty holding and controlling a pencil to write correctly.
The
earlier the diagnosis of dyslexia the easier it will be help patient.
Factors like depression, self esteem should always be in check when
dealing with a dyslexic individual.
What are the signs of dyslexia?
Children in kindergarten affected
with the disease often find it hard to identify the alphabets,
struggles to blend sounds together or rhyming words or pronounce
correctly and probably has a smaller vocabulary than children in the
same age group have.
Older children
with the disease struggles with reading and spelling, has difficulty
using proper grammar and sounding out unfamiliar words, has difficulty
summarizing a story or learning a new language.
This
often leads dyslexic individuals to frustration and low self-esteem.
Because their brain is wired differently and they process information
differently, trying a different teaching strategy can help patients.
The
usage of various educational strategies could help a dyslexic to read
and write. Research has shown that dyslexic individuals who were
prevented from going through stress and anxiety improved in written
comprehension.
How do I help my dyslexic child?
There are several strategies to improve a dyslexic patients reading, writing, pronouncing and spelling skills;
- Note that not all children are the same, so identify what works with the patient in question.
- If reading is the child’s challenge, try audio books.
- Try a decongested lecture note material instead of a chunky note.
- Use multi-sensory teaching skills.
- Try using larger and less complicated alphabet fonts.
Compared
to most dyslexics who have problems reading, writing, spelling and
pronouncing, Chinese dyslexics have challenges converting Chinese
characters to their meanings.
To explain how dyslexic individuals read, a web page was written with Javascipt to give non-dyslexic individuals an idea of what dyslexic individuals see words.
Although
the percentage of percentage of people with dyslexia is still unknown,
but scientist have estimated the percentage of the disorder to be as low
as 5% and as high as 17%. Report also says that males are most likely
to be diagnosed with the disorder than females.
Another
research have shown that font designs can have effect on dyslexic
patients. Because of the believe that many Latin alphabets are visually
similar, specific fonts for dyslexic individuals were created. These
includes, Dyslexie, OpenDyslexic and LexiaReadable. With these fonts, every letter is distinctive from the order.
So far, there are no
tests to determine a dyslexic patient, but one can get a diagnosed by a
team of professionals. These professionals will test the child’s vision
and hearing to confirm it is not the cause of the reading disorder.
The
child may also be tested a psychologist. The child will be asked to
read rhyme words, spell, and write. Psychological tests can help
determine conditions like attention-deficit/hyperactivity disorder, anxiety; depression might be associated with the reading disorder.
Findings from the test will help improve your child’s understanding on how sounds and letters work.
