I was the same way during my mixed episode. Still can't even imagine reading an actual book, even though I used to be a voracious reader and could finish a 900-page book in 3 days if it was a good one.

My concentration has gotten a lot better in recent weeks, but I still haven't regained my customary attention span......hopefully that will come as things continue to improve all the way around. For a while I was afraid I was developing early-onset Alzheimer's, but my pdoc said it was part of my particular brand of BP and not to worry too much because my memory would pick up when the meds started working. Now I can even remember some stuff without having to write it down on sticky notes.
