Dyslexia originates from the nervous system and is a familial difficulty in learning or processing a language. According to individual differences, the severity will be different, and it is common that language, reading, writing, spelling, writing and mathematics have difficulties in repetition and expression. These problems are not directly caused by lack of motivation, sensory impairment, inappropriate teaching skills and environment. This is an abnormal neuropsychological function, which affects nearly 10-20% of the population to varying degrees.
However, dyslexia is not necessarily related to personal intelligence, but reflects a problem on the road to intelligence. People with dyslexia do not mean that they can't read or have insufficient IQ; However, due to the communication barriers between the brain and the cerebellum, the learning process of these people will be extremely difficult. Unless the problem of reading and writing is solved, these people are likely to avoid everything related to reading, writing or spelling, avoid communicating with others and stay away from the crowd.
