Recent experiments indicate that peripheral glucose administration enhances memory in rodents and humans. This study examined the effects of glucose on memory and nonmemory measures of neuropsychological functioning in elderly humans. Healthy older adults were given a series of neuropsychological tests after drinking glucose- or saccharin-flavored lemonade. A repeated measures design using counter-balanced beverages and tests was used. Glucose enhanced performance on declarative memory tests but not on short-term or nonmemory neuropsychological measures. Glucose tolerance predicted performance on declarative memory tasks but not on other measures.
