Easily distractable and poor concentration are symptoms of several disorders. I've always had problems socializing (loose my train of thought, go off on tangents, can't put thoughts together). Socializing is like lifting weights for me. Had trouble one semester in college taking tests because of others making noise and I failed a couple classes.

Paxil gave me a boost in late 90's, got off SSDI and started working FT then symptoms came back few yrs later, went back on SSDI. Presently ritalin has really helped to decrease my irritability/agitation and increase concentration. Actually got thru a meal with family last weekend w/o losing concentration and/or becoming irritable and feeling drained. First time that's happened in yrs.
