In patients without CVD, attention and language domains were comparable to norms. The MMSE detected cognitive impairment in 2% of studied patients, significantly fewer than when the ACE\u2010R was applied (32%). Age, gender, diabetic status and depression were associated with lower neurocognitive screening performance (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u2009.05).

CVD confers poorer performance in attention and language domains. The MMSE is ineffective in detecting subtle NCI in this population compared with ACE\u2010R. Risk factors for NCI include age, gender, diabetic status, depression and vintage beyond 12\u2009months.
