That makes no sense that your son gets Medium Care and Low Disability with Aspergers Syndrome unless the DLA has messed up my claim or your sons claim. I get Medium Care and Low Rate Disability for having both Aspergers Syndrome, Epilepsy, Short Term Memory Loss, Worchester Draught Syndrome and Arthritis so I don't know how that works out. If you can get the disability element put up a grade then that means that they are not using base reference for different conditions (Also before anyone says that his maybe worse, I frequently almost get run over by cars because I don't think to look and I can't recognise dangers)
