There is no one test that can be used to diagnose dyslexia. A variety of aspects are taken into account, including your child's growth, educational challenges, and medical history. Your doctor will also look at various skills your child has problems with, such as reading material written at a different pace, spelling words, or using grammar correctly. Dyslexia is often present from an early age. If you have concerns that your child may have dyslexia, ask their teacher for an assessment or consult with another member of the school staff such as the parent support worker. The earlier it is detected, the more effective treatment can be. Your doctor may suggest certain strategies for teaching your child to read better. For example, some children who struggle with dyslexia benefit from special programs designed to help them learn how to recognize letters and words on the page. These programs use different techniques, such as highlighting frequent letters or words, to help children learn what they need to know. Some doctors believe that dyslexia is preventable if someone is born with a genetic predisposition to the condition. However, most cases of dyslexia are not due to genetics but rather to environmental factors.
