Dyslexia is a kind of special learning disabilities, mainly due to congenital abnormalities in brain structure and function. When a certain part of the brain develops abnormally, the function of word processing is affected, which makes it difficult for children to grasp the connection between the pronunciation, shape and meaning of words.

Children with dyslexia often have difficulty in recognizing, reading and silently writing words accurately and fluently. This may be related to the difficulty in distinguishing the pronunciation and shape of words when children are reading and writing. Due to difficulties in reading and writing words, children will also have problems in reading comprehension. Some children may reduce reading as a result, which affects the number of word recognition and overall cognitive development. The following are common symptoms of dyslexia: for example, when reading, reading speed is slow, tired easily or headache; often confused words with similar fonts or similar meanings, etc. When writing silently, you often increase or decrease the strokes and change the direction of the strokes.

Children with dyslexia often perform far inferior to other students in language subjects, but their intelligence and sensory functions are normal, and their literacy problems are not caused by lack of education or learning motivation.
