The association between cognitive function and mortality is of increasing interest. We followed 1870 men aged 55-69 years at cognitive assessment for 16 years to establish associations with all case and cause specific mortality. Cognitive assessment included AH4, 4 choice reaction time (used as estimates of mid-life cognition) and the National…

Participants were 48 relatively healthy Caucasian men…
