Exercise won’t improve your ageing memory after all, a new study suggests. Researchers found no evidence to support a widespread belief that running or cycling, for example, combats that irritating inability to instantly recall names. They studied its cognitive effect (with that of mindfulness training – or both combined) on older adults who reported age related memory changes but had not been diagnosed with any kind of dementia. But don’t imagine their findings are licence to become a couch potato. The study’s first author, Professor Eric Lenze, head of the Psychiatry Department at Washington University in St Louis, notes that there is no doubt exercise is beneficial for older adults’ physical health and that mindfulness training reduces stress – which is bad for the brain.
