Kenny et al. are wrong in their assertion that because the medical evaluations of 92 children with an assortment of problems affecting their ability to learn in school showed no consistent pattern, medical evaluation has little to offer such youngsters. Denhoff et al. have shown medical evaluation can be very helpful.
Lumping all children with school problems together and looking for common symptoms is indeed a fruitless exercise. Kenny et al. do not permit the reader access to the specific data on which they base their conclusions, nor do they even provide general data on the subgroups within the larger group of youngsters.
