Older people who are concerned about memory loss might want to take a look at their diet.
According to Nancy Morse, senior scientific officer at Efamol, good nutrition is "vital for brain function".
She added that fish oil components such as docasahexaenoic acid (DHA) are especially important.
"In the UK, we currently consume less than half the suggested daily intake of DHA, and research has shown that people with lower than normal levels of DHA, have a greater tendency to experience memory problems as they age," remarked Ms Morse.
The comments follow research from Efalex, which found that 71.3 per cent of people over 50 have experienced regular short-term memory issues.
Furthermore, over 50 per cent of people admitted to avoiding addressing friends or family by their name because they couldn't remember what it was.
The research also revealed that 51 per cent of people over 50 admit to worrying about their health more than any other single issue.
