The problems displayed by individuals with dyslexia involve difficulties in acquiring and using language–reading and writing letters in the wrong order is just one manifestation of dyslexia and does not occur in all cases. Other problems experienced by dyslexics include:
- Learning to speak
- Organizing written and spoken language
- Learning letters and their sounds
- Memorizing number facts
- Learning a foreign language
- Correctly doing math operations
Not all individuals who have difficulties with these skills are dyslexic. Formal testing is the only way to confirm a diagnosis of suspected dyslexia.
