Researchers report the brain connections that are key to cognition and complex thinking skills are most effected as we age. Impact of ageing on brain connections mapped in major scan study. Brain connections that play a key role in complex thinking skills show the poorest health with advancing age, new research suggests. Connections supporting functions such as movement and hearing are relatively well preserved in later life, the findings show. Scientists carrying out the most comprehensive study to date on ageing and the brain’s connections charted subtle ways in which the brain’s connections weaken with age. Knowing how and where connections between brain cells – so-called white matter – decline as we age is important in understanding why some people’s brains and thinking skills age better than others.
