Which of the following is not true about children with dyslexia?

The assertion that all children with dyslexia are diagnosed by the age of 7 is not true. Dyslexia is a specific learning disability that can manifest differently in each child, and the age at which a diagnosis is made can vary significantly. Many children may not exhibit noticeable difficulties with reading until they are older or may not receive a formal diagnosis until they are in later grades. Early detection and diagnosis can be beneficial for intervention, but it is not universally the case that all children with dyslexia will have a diagnosis at such a young age.

In contrast, children with dyslexia can indeed learn to read with proper instruction, and many show strengths in areas that may not be directly related to reading, such as problem-solving or creative thinking. Additionally, the cognitive load associated with reading tasks can be particularly challenging for these children, leading to difficulties in managing multiple demands on their cognitive resources.
