Dyslexic?

In response to Mr Tay Wenbin's question.

Dyslexia

Dyslexia is a neurological, genetic based disease affecting 5% of the population. The cause of dyslexia is genetic based which means mutations in germ line (sex cells) can cause an offspring to have dyslexia. Dyslexic people have compromised reading and writing abilities and intelligence which is significantly lower than which would be predicted by his general level of intelligence. This is because of decreasing amounts of gray matter in the parietal and temporal lobe (please refer to above image). In layman terms, the amount of gray matter in the brain is directly proportionate to the intelligence of a human.

There are many characteristics of Dyslexia. Some of which are silent characteristics, which means that they are not shown outwardly. Some of these characteristics are reading and writing disabilities and complaining of dizziness, headaches or stomach aches while reading. This entry will not go into the further symptoms of dyslexia.

Dyslexic people tend to look at words as pictures and thus are slower in comprehending.

Treatment of dyslexia is based mainly on phonological training, which involves breaking down and rearranging sounds to produce different words.

As of my knowledge, dyslexic people are born dyslexic from birth. No non-dyslexic turns can turn dyslexic at any point of his/ her life.

I hope this answers your question. If you have any feedback, please tag on my tagboard.
