Another product looked at was the £88 Mindfit for the PC, which the company says "exercises important abilities that are… known to decline in later life, such as short-term memory".

However, results did not show that it was any better than standard computer games such as Tetris, said Dr Adrian Owen, a senior scientist at the Medical Research Council's Cognition and Brain Sciences Unit.

The team also looked at Lumosity online training system, which costs £4.99 a month, MindSpa, a £175 system which uses audiovisual stimulation to promote relaxation and increase focus, and the £9.99 Test and Improve Your Memory computer programme.

None of the manufacturers' claims on improved cognition are supported by evidence that meets the minimum standard by which scientific research is judged, the panel said.
