Is there a typical WISC profile in APD and do profiles change over time - become dyslexic etc?

[KOKOagainandagain]

My DS was seen by the CPOC Vision Training clinic in 2008 (age 7) and had various problems (auditory processing, ocular-motor functions, hand-eye sequencing, retained reflexes etc). At school his attainment was above average (2b, 2a and 3 in Yr 2 SATs) but he did not work at all independently - blends into the wallpaper rather than disruptive. He was seen by the LEA Ed Psych in 2009 using WISC-IV who had no concerns about cognitive functioning - all but one of the subtests scored between the 50th and the 93rd percentiles, only the digit span was low but when combined with the symbol search score which was on the 50th percentile, overall working memory was on the 27th percentile.

I will skip the many battles over the last four years to private assessment by an independent EP in September 2011,using the WISC III, in which 5 of the subtests (both verbal and performance) were between the 5th and the 8th percentiles and he was diagnosed with three SpLD - dyslexia, dyscalculia and dyspraxia and possible inattentive ADHD (although SNAP screeing tests sent by the Comm Paed were negative). He has been referred to the APD clinic at GOSH. At school he is still unable to work independently - doesn't even write the title and date without prompting and is unable to work at all on some tasks (eg writing an advert) without full and continual 1:1 support. On teacher assessment he is still working at level 3 - learning gaps have developed and increased year on year. In recent SATs tests he has scored less than level 2 (0% - 12%).

He was assessed again by an LEA EP in July 2011 but she carried out Nelson Insight assessment as the situation at school had led to a transfer of primary schools on medical grounds (school phobia) and the development of numerous tics (blinking, coughing, snorting, sniffing, facial grimaces etc). Whilst this is useful in collecting data on the damage caused to children by educational failure (!) we expected that she would repeat the WISC-IV carried out 3 years earlier. She said that the assessments remain the same over time. She also said that DS was not dyslexic as he could 'read and write' and appears to have reversed the findings of the Comm Paed so I am questioning the reliability of what she said. Can anybody help? Perhaps Dolfrog?

My Ds was also assessed in 2008 aged 7 using the WISC, At the time he scored poorly in most things although he had a spiky profile. The EP said at the time that she found it difficult to interpret the results and didnt know if he was capable of more. Recently he had another WISC where he scored in the average range for the verbal and perceptual reasoning components, a bit below average for working memory and a good bit below average for processing speed. The EP was amazed at the change in his scores, particularly the VC and PR scores which changed dramatically . It seems a more accurate reflection of his capabilities this time round ie his processing speed is his biggest issue with it making his WM weaker by having to work harder than it should. He is currently being assessed for AS also . I dont think you should see a change over the years as IQ should remain constant but I believe the EP first time round was not able to access his IQ at that stage

I remember someone else saying that in the earlier years the tests for younger children tend to rely on knowledge of concrete facts rather than abstract thinking so if you have a low score to start with then this could reduce. This isnt the case with your DS though. It seems strange that a score would change that much the other way round. I dont really know what the difference between the WISC 111 and Wisc iv is . My DS had the wisc iv in both instances. He also has auditory processing and sensory processing issues and finds it hard to do things independently. Sorry - not much help really
