The term "dyslexia" is used to describe a number of problems associated with reading, writing or spelling. Short-term memory, mathematics, concentration, personal organization and sequencing may also be affected. We do not know exactly what causes dyslexia, but we do know that it tends to run in the family. We also know that more boys suffer from dyslexia than girls and that dyslexia is more common in urban areas than in rural.
One of the most common signs of dyslexia is "reversals". People with this kind of problem often confuse letters like "b" and "a" when reading and writing or they sometimes read and write words like "tip" and "won" as "pit" and "now". Other common characteristics are lack of punctuation, misspelling, mixed-up sentence structure and poor grammatical construction.
People are born with dyslexia, but it is only when they begin to learn to write that it becomes a noticeable problem. For children with dyslexia, going to school can be a traumatic experience. Poor achievement can make them feel frustrated and insecure. They are reluctant to go to school and sometimes even skip school together, Cheating, stealing and experimenting with drugs can also occur when children regard themselves as failures.
It is a common misconception that dyslexic people are of inferior intelligence. Yet Albert Einstein, Leonardo da Vinci, Thomas Edison and Hans Christian Andersen were apparently all dyslexic. There is no total cure for dyslexia; however, the effects of dyslexia can be lessened with the guidance of skilled specialists and a lot of determination.
