I've always felt like I'm in a fog! I went through my entire childhood with ADD Inattentive type and was never diagnosed until 5 years ago (at 38) I often wonder how differerent my life would have been had I been treated for this years ago. But I've never heard the term Sluggish Cognitive Tempo. Is used to describe the processing difficulties associated with ADD? While I was always considered bright, on many things I was (and still am) one step behind everyone. I see it now with my son, and the reactions of his teachers are so frustrating. Things just don't occur to him like they do other kids, and he needs to be prompted for a lot of things. He tends to be accused of laziness much of the time and I will admit, that is how it appears on the surface. I find Adderall to be immensely helpful, but don't want to become dependent. I've never heard of Vyvanese. Is it also a stimulant?
