Cognitive effects of pregabalin in healthy volunteers

a double blind, placebo controlled trial  Salinsky M, Storzbach D, Munoz S.  Neurology 2010; 74: 755-761.

32 healthy volunteers were randomized to pregabalin (300 bid) or placebo for twelve weeks and underwent cognitive tests before and after.  Subjects on pregabalin showed worse performance on 3 of 6 target cognitive measures, including digit symbol test, Stroop, and Controlled Oral Word Association Test.  They were paralleled by changes on the Portland Neurotoxicity Scale.
