Glucose and memory: fractionation of enhancement effects?
Abstract Recent research findings indicate that glucose administration enhances some aspects of cognitive functioning . To date , those studies which have investigated the effects of glucose on memory in human participants have concentrated on its apparent ability to attenuate memory impairment . Relatively little research has been done in humans investigating the effects of glucose on memory performance in young healthy participants in whom no memory deficits exist . Moreover , the work which has been conducted in this population has produced somewhat equivocal findings . In this study , after overnight fasting the influence of a 25 g oral dosage of glucose on a range of measures of memory performance was investigated in healthy young female participants . Two control treatments ( saccharin and water ) were also administered . There was a significant glucose facilitation effect upon performance of long-term verbal free and cued recall tasks which did not vary with test delay . Performance on these free and cued verbal recall measures correlated significantly with blood glucose levels across all participants . No glucose-related facilitation was observed on either a test of short-term verbal memory ( forwards/backwards digit recall ) or a test of long-term non-verbal memory ( complex figure reproduction ) . However , the significant glucose-related effects observed with long-term free and cued recall remained after controlling for participants ’ differential baseline blood glucose levels and individual levels of immediate memory performance . Therefore , memory improvement after glucose ingestion was not merely a consequence of lower baseline blood glucose or lower immediate memory performance in the glucose treatment group . These findings indicate that there may be some fractionation in the memory facilitation effects of glucose : the memory enhancing effect of glucose administration in healthy young adults may be greatest on tests of long-term verbal recall . The results suggest that glucose may enhance retention in and /or retrieval from long-term verbal memory
