Has anyone ever seen or know anything about a WISC score dropping dramatically over 2 1/2 years? Short version of the story…tested DS 2 1/2 years ago. Dx EG with no 2E. Struggles in school over the past 2 1/2 years, school and I decide to test him again. Again EG and no 2E. Biggest outliers to me are drops in WMI from 81% to 68% and PS from 84% to 50% (VCI, PRI and FSIQ stayed consistent). Any thoughts?
