Glucose drinks boost memory

19th January 2006

People with dementia could boost their memory functions by "consuming a glucose drink", say the authors of a new study.

Despite all the usual health warnings over drinking too many sugary drinks, researchers have suggested that they could actually be beneficial to those suffering from dementia, reports DNA Evolutions.

Focussing on the hippocampus, which is hit by the onset of dementia and is responsible for creating new memories, they used 25 volunteers to measure the effect of sugary drinks on the memory.

The study showed that the volunteers who consumed 25 grams of sugar remembered 11 per cent more words, while taking in 50 grams improved memory recall by 17 per cent.

Leigh Riby, one of the authors of the study, said: "Our research shows that consuming a glucose drink can significantly boost memory recall.

"It is widely accepted that when humans face a stressful situation they experience a natural rise in glucose in the body, particularly in the hippocampus."

Ms Riby added that this led to a clearer memory recall and that the "glucose-memory" system could be used to train the body to retain glucose supplies for longer, therefore increasing memory recall in older age.
