Cognitive function in healthy older European adults

Baseline data are reported from a study of the effects of Zn supplementation on cognitive function in older adults as assessed by the CANTAB computerised test battery. This is a multi-centre prospective intervention study employing a randomised double blind design. There are 387 healthy adults aged 55-87 years from centres in France, Italy and Northern Ireland. Measures of visual memory, working memory, and attention were obtained at baseline (prior to supplementation Younger adults (<70 years) performed significantly better than older adults (>70 years) on all tests, with minimal differences between centres. In addition, men outperformed women on tests of spatial span, pattern recognition memory, and reaction times, although these gender differences varied somewhat between centres. The results are generally consistent with previous age- and gender-related effects on cognitive functioning.
