What Causes Dyslexia?
The causes of dyslexia are still being researched. The most recent studies seem to show that it may be a chemical imbalance of genetic origin. One study seemed to indicate an abnormality in the cell arrangements of the brain. Existing evidence indicates that it is hereditary. The probability of dyslexia has been traced through several generations of many families. Since dyslexia frequently goes undiagnosed even today, it isnt always possible to secure clinical proof. However, it is not unusual to discover a father, uncle, aunt, or other relatives who have the problem to some degree.
Dyslexia is now firmly established as a congenital and developmental condition. Its cause has not been fully confirmed but the effect is to create neurological anomalies in the brain. These anomalies bring about varying degrees of difficulty in learning when using words, and sometimes symbols. For a more detailed explanation of the causes of dyslexia click here.
So far, there are nine genes that are known, with the probability of more to come. There is an innate basis, in other words, for this as for other specific learning difficulties. Optimal teaching can however minimise – as poor teaching can aggravate – the effects of this biologically-based disorder.
The exact causes of dyslexia are still not completely clear, but anatomical and brain imagery studies show differences in the way the brain of a dyslexic person develops and functions. Moreover, people with dyslexia have been found to have problems with discriminating sounds within a word, a key factor in their reading difficulties. Dyslexia is not due to either lack of intelligence or a desire to learn; with appropriate teaching methods dyslexics can learn successfully.
The exact causes of dyslexia are still not completely clear, but anatomical and brain image studies show differences in the way the brain of a dyslexic person develops and functions. Moreover, people with dyslexia have been found to have problems identifying speech sounds in words and how letters represent them. This problem is associated with many other speaking, reading, and writing difficulties. Dyslexia is not due to either lack of intelligence or a desire to learn; with appropriate teaching methods, most dyslexics can learn successfully. It is known that dyslexia is heritable, and therefore, it is not uncommon to have multiple members of the same family with reading problems.
