DS is only 6 and so far has an ADHD (combined type) diagnosis. He also suffers from SPD, which goes hand in hand with the ADHD. Plus, DS has slow processing speed, which could mean he has executive funcitioning issues. How different is EFD from ADHD? I know DS and a diagnosis are a moving target and things will constantly be changing. I'm wondering when EFD can be diagnosed (and who does it). I see aspects of ADHD and aspects of EFD in DS now.
