Please help - cognitive impairment & snri?

Don't go there. Snri=selective norepinephrine reuptake inhibitor=class of antidepressants whose action on neurotransmitters is distinct from ssri's(which act by affecting serotonin).It's tempting to hope the transmitter that is "cousin" to adrenaline would be more cognitively empowering but it doesn't work out that way. These meds (cymbalta, effexor, (venlafaxine) pristiq) are useful for some, but for mood issues, not cognition.
