Types of Dyslexia
Phonological Dyslexia
The
well-known type of dyslexia, as the word stated by it-self someone who deal
with difficulties in understanding and using phonics. Such type of person face
problem in matching sounds to symbols and in breaking down the sounds of the
word. Such individual face difficulties in distinguishing phenome e.g., cat and
cut, pat and bat, God, and log. Individual also face problem in distinguishing
alphabets like p and q, b and d. it’s surely believed that this type of
dyslexia is the most common type of dyslexia.
The
best documented way to teach a phonologic dyslexia individual are based upon of
the Orton-Gillingham approach to reading that was developed in the 1930's by
Samuel Torrey Orton and Anna Gillingham.
Naming Dyslexia
Person
who struggles to name rapidly the color, number and letter may suffering from
naming dyslexia or also called Rapid automatized naming (RAN) dyslexia. Such
person can also face problem with reading and speaking speed. Person know the
correct name of color, number and symbols (letter or alphabet) but it often
take time to say the correct one.
It
can be believed that rapid naming dyslexia can be linked to specific gene that
is inherited that control how the brain processes the reading and language.
Some other factors that can cause naming dyslexia are:
Use or exposure to alcohol, drug, and nicotine during pregnancy
Premature birth
Paternal infection that affects brain development
Person
having disability can be treated with the help of expert to process language.
Special curriculum is designed to treat the person.
Double Deficit Dyslexia
Double
deficit dyslexia are also known as double dyslexia. A person facing problem
with tow aspects in processing language. Or in simple terms, in double deficit
dyslexia a person struggling with both phonological dyslexia and rapid naming
dyslexia.
Such
type of person face problem in matching sounds to symbols, breaking down the
sounds of the word, and struggle with rapidly naming the color, number, and
letter. Such type of dyslexia is uncommon.
Surface
Dyslexia
Person
who can easily pronounce bre words but fail to pronounce or read irregular
words (words who's spelling, and pronunciation don't match) for e.g. yacht,
colonel, chaos debet etc.
This
type affects words, words don't sound the way the spelled that's why they need
to be memorized because making it further tough to sound.
The
signs of surface dyslexia include trouble in reading new words ny sight,
difficulty with spelling, severe difficulty with word recognition, slow to read
and avoid reading activities.
Person
troubling with both phonological dyslexia and surface dyslexia is uncommon.
Visual Dyslexia
Child
facing difficulty to remember pictures or words that they saw on page they may
have visual dyslexia. People experience visual disturbances when they read.
Dyslexia affects the visual processing makes the brain get incomplete picture
of what the eyes see.
Visual dyslexia can be treated with vision therapy. It starts with complete eye examination to check the sharpness and clarity of vision. Vision therapy includes wearing eye patch, looking through prism, looking letter finding puzzle and wear tinted glasses.
Primary Dyslexia
If
dyslexia are genetically inherited form parents to offspring, Such condition is
known as primary dyslexia. Parents suffering dyslexia increase the risk of
development dyslexia in their offspring/children.
In
primary dyslexia left side of brain cerebral cortex is damaged. More often
found in boys than girls. It doesn’t change with age.
Secondary Dyslexia
As
we know dyslexia is neurological problem, if brain development issues occur in
womb that causes dyslexia, then such type of dyslexia is Known as secondary
dyslexia. As development disability cause dyslexia at birth therefore both
primary and secondary dyslexia are said to be developmental.
Acquired Dyslexia
If
any brain injury or trauma affects the part of brain that is responsible for
language then, sometimes it also causes dyslexia, this type of dyslexia is also
terms as trauma dyslexia or acquired dyslexia. It's the only type of dyslexia
with a known cause.
Language
disturbance is general due to any distribution in brain, if distribution occur
in right- it leads to visual processing problems whereas problem in left-brain
results in a linguistic deficit.
