This situation got much worse for me when I started feeling the onset of my Major Depressive Disorder, and Generalized Anxiety Disorder. I do believe that this tendency is strongly linked to these illnesses. It may also be a possible facet of other ailments.

It happens to me more when I am stressed and feeling myself 'drop' a bit.

My husband has complained of it happening to him as well; but I think for his part, it's because he is a tad hyper, and takes on an awful lot of things at once.

My focus and attention have gotten a little better with a med increase I initiated in the Springtime. I am delighted!

Try and practice memory games and intelligence games as often as you can. By also, consistently doing this, I've gently forced myself to regain an awful lot of things I once considered, "lost", to me. Experts also do recommend doing this to stave off memory loss and inattention problems as we age.
