The hippocampus, that little seahorse-shaped organ in the lower center of the brain, is involved with both emotions and memories. It makes sense that this disorder, which targets emotion, would also impact memory.

On the personal level, yes, I have been plagued with a poor memory, also. ...before the ECT, so ECT just dug the holes in my memory a little deeper.

I'd be interested in learning how many of us also struggle with spatial navigation. That is the third thing the hippocampus is in charge of. I suspect an academic study, if anyone did one, would show bipolar performance to be sub par.
