Did the psychologist administer any tests beyond the IQ tests? It would be helpful to see how she did on tests that measure visual perception, visual memory and visual integration. Reversing letters and or numbers is not uncommon at age 6. The visual system is still developing.
If your psychologist gave you a full evaluation report that includes test scores, interpretation and recommendations, this would be the first step to understanding what exactly the potential LD might be. If he or she did not provide such information, I would contact her to get more clarity. The good news is that your child is still young and developing. If intervention and remediation is needed, you are catching it early - and this generally leads to more favorable outcomes since the brain has more plasticity at this age and usually responds better to interventions.
