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./.../
