Dyslexia
I. What is Dyslexia?
Dyslexia is one of the specific learning disabilities. Children with dyslexia have difficulties in word recognition, word reading and dictation. It is not caused by intellectual disabilities, sensory impairments, environmental factors or emotional problems.
II. What are the symptoms of Dyslexia?
Word recognition and reading:
- Fail to recognize and read characters or words. Make frequent errors in pronunciation despite repeated studies.
- Mixing up of characters with similar shape, e.g. pronounce "毛"as "手"
- Mixing up of words with similar or related meaning, e.g. read "快樂" as "高興", "秩序" as "規則"
- Slow in reading and sometimes may skip words or lines
- Becomes easily tired or may have headaches during reading
Writing to dictation:
- Fail to accurately recall simple words in dictation despite repeated study
- Wrong patterns in words, including addition or deletion of strokes, e.g. "春" as "". Reversal of left-right stroke sequence, e.g. "世" as "".
Reversal of left and right component of a character, e.g. "如" as "𠯆".
- Performance in unseen dictation by listening is usually worse than dictation of memorized passages
- Characters written stroke by stroke slowly and in wrong sequence, due to weakness in word recognition
* These common symptoms of dyslexia may not be all present in the same child
III. What causes Dyslexia?
Dyslexia is partly attributed to hereditary factors. The difference in development of certain brain processes affects the word processing function. Affected children therefore have difficulties in relating sound, shape and meaning of words.
* Research indicates that cerebral palsy affects approximately two per 1 000 children

IV. How does Dyslexia affect children?
Academic Performance:
Since children with dyslexia always fail in dictation and examinations, they gradually lose interest in study and learn with lower efficiency, leading to poorer academic results.
Behaviour and Emotion:
Most children with dyslexia dislike reading, writing and homework.? To avoid failure, they try to evade these, cover up their learning difficulties by behaving uncooperatively. Studies show that around 30% of children with dyslexia also have attention deficit disorder, and may be inattentive or daydream in class.
Self image:
They are often considered naughty or lazy before diagnosis, leading to low self-image and self-confidence.
Family:
Parents' failure to understand or face the problem would affect parent-child relationship and increase the child’s psychological burden. Therefore, parents' acceptance is important for helping these children express their feelings and overcome difficulties.

VI. How can parents help their child with Dyslexia?
Though dyslexia cannot be cured at present, counselling and effective teaching strategies can improve children’s learning.
Early diagnosis and training
After diagnosis, early training in reading, including recognition of Chinese words and radicals as well as English phonics, can enhance children’s ability and minimize their resistance in word learning.
Understand and face the problem
Understanding of the condition can help parents set reasonable expectations for their children. With adequate knowledge and strategies, parents can work effectively with the school in supporting the child.
Contact with teachers
Communication between parents and teachers can enhance parents' understanding of their children's progress. Through discussion, both parties can work together to come up with the most effective mode of learning.
Create successful experience
Identifying strengths and potentials of children can help them acquire successful experience and gain self-recognition.
Experience sharing
Sharing experience and establishing mutual support through parent self-help groups can help parents face the problem positively.
