ABSTRACT
The putative beneficial effects of caffeine on cognitive performance may vary between ages. The acute cognitive effects of 100 g caffeine on memory functions and focussed attention were investigated in sixteen middle-aged (45-60 years) and fourteen elderly (60-75 years) healthy men and women according to a cross-over design. Caffeine did not affect short-term memory span or speed, long-term memory retrieval functions or focussed attention. It is proposed that in middle-aged and elderly subjects cognitive effects may occur predominantly at higher caffeine dosages.
