What Are The Different Types Of Dyslexia? – An Overview
A learning disorder, dyslexia affects a child’s ability to read, write, spell, understand, and in some cases speak properly. Learning more about the different Types Of Dyslexia would help us all understand a bit more about the disorder better. The earlier the symptoms are identified the better, because it can be treated sooner and the child will benefit.
Different Types Of Dyslexia:
The various types of this disorder are categorized depending upon the symptoms. It can adversely affect reading, writing, spelling, numbering, sequencing, and in some cases speaking abilities.
1. Primary Dyslexia:
This type of disorder is a result of some dysfunction of the cerebral cortex – an abnormality or disturbance in the normal brain function. The injury damages that part of the brain which is related to the language and learning. A child or a person suffering from this type is rarely able to learn anything above fourth grade. This disorder is genetically passed on and as an adult a person faces severe challenge reading, writing, and spelling words correctly.
2. Secondary Dyslexia:
Secondary dyslexia is a type of disorder that results from some hormonal developments while the fetus is still in the developing stages. This is also called as developmental dyslexia. And, with age, developmental dyslexia diminishes in children. Usually boys are more affected by it than girls.
3. Trauma Dyslexia:
Any injury or trauma to the brain usually results in this type of dyslexia. But it is a rare case. This form affects a child’s reading, writing, and learning abilities.
4. Visual Dyslexia:
This form of disorder troubles the child or person with numbers and letters. The sufferer finds it hard to remember and write the numbers,
letters, and symbols in correct sequence. The most prominent feature
of it is that the sufferer writes the letters in reverse. For example they write ‘b’ in place of‘d’.
5. Auditory Dyslexia:
When a child has problem understanding the different sounds of letters, then the form of disorder is called auditory dyslexia. This disability is not restricted to only some letters, but also to a group of letters too. This happens when the child fails to identify all the different sounds and confuses them. This makes it hard for them to understand and differentiate the sounds.
6. Dyslexia With Dysgraphia:
This form of disorder is also called as deep dyslexia and it negatively impacts writing, pronouncing, understanding and grasping the meanings of some words.
7. Without Dysgraphia:
This condition is some times hard to diagnose because it mostly impacts the reading abilities and not the speaking and writing skills. It is also called as pure dyslexia, and a person faces difficulties doing mathematical problems. Reading numbers is hard for the sufferers of this condition. The oral language, spelling words, and writing abilities are usually unaffected and this can hinder in identifying this condition.
8. Neglect Dyslexia:
A child neglects or fails to notice one side words of the compound words. They overlook either the left or the right side of the word and pronounce only half of the word. For example, when pronouncing a compound word like ‘bookshelf’ they either say ‘book’ or ‘shelf’. And ignore the other half.
9. Spelling Disorder:
This disorder is evident when a child or a person has difficulty spelling any word. They read each letter of the word and they read very slowly. In some cases they fail to recognize certain letters.
This type of dyslexia occurs when a person finds it hard to understand the meaning of words. This happens because the patient or the sufferer of the condition distorts the spelling or confuses it with some other related word. He can confuse the word with its antonym or synonym, and hence the trouble.
These are a few types of dyslexia that can create problems with a person’s daily life activities and can frustrate him to no end. The earlier it is identified; the sooner it can be treated by a neuropsychologist or a developmental pediatrician.
