London - One in seven young adults suffers memory problems – and attention-sapping technology may be partly to blame, researchers warn.

A study found memory lapses are not just the preserve of the elderly, with 14 percent of those aged between 18 and 39 worried about their recall.

With links between absent-mindedness and dementia, the US researchers said that the young need to look after their minds.

The University of California team commissioned a health and lifestyle survey of more than 18,000 people aged between 18 and 99. When asked if they had any problems with memory, 20 percent said yes.

Unsurprisingly, those aged 60-plus had the most memory problems but researchers were taken aback by the high level among 18 to 39-year-olds.

The researchers said young people may be particularly affected by stress and the memory-sapping effects of multi-tasking. Using a phone, computer and other gadgets at the same time may shorten attention span.

Depression, low levels of education, lack of exercise and high blood pressure are also risk factors. The team advised taking regular exercise and constant learning, in the form of classes or new hobbies, to minimise risk. - Daily Mail
