We were suspecting ADD/dyslexia. Her father and brother both have it and
she is struggling in school. Can you tell me if these scores show any
possible concerns for either of those LD's. She is also in speech for
some slight speech problems but has shown improved.
Thank you.
A:
Her scores do show some signs of a learning disorder. You did mention
that her father and brother both have learning disorders; hence it is
not surprising that she could have it as well.
Based on the scores alone, there is lesser possibility of ADHD as
children with ADHD generally have a much higher full score IQ (around
97-98 points). They also tend to have a higher working memory index
(around 96 points). I would suspect a dyslexic condition as her scores
are close to that of an average score for children with dyslexia.
Specifically, it appears that she may have a reading LD based on her
scores. The average score for someone with a reading LD would be:
| Verbal comprehension index |
91.9 |
| Perceptual reasoning index |
94.4 |
| Working memory index |
87 |
| Processing speed index |
92.5 |
| Full scale IQ |
89.1 |
Your daughter's score fits in the reading category, hence the diagnosed
based on average scores. However, it is best to refer to and seek advice
from an educational psychologist for a more firm diagnosis upon
conducting more tests. Once the diagnosis is confirmed, there would be
suitable intervention programmes to help her cope with her learning.
Best wishes to you.
