Are Specific Language Impairment and APD distinguishable?

Specific language impairment (SLI) and APD appear intertwined, with the suggestion that differential diagnosis may be influenced by whether a child is assessed by an audiologist or speech-language therapist. Multi-disciplinary assessment (as occurs at SoundSkills) is advisable. Ferguson, M. A., Hall, R. L., Riley, A., & Moore, D. R. (2011).
