Your brain changes at 9, 32, 66, and 83
Brain scans of 3,802 people show how the brain’s structure changes at four major turning points.
Your brain changes at 9, 32, 66, and 83
A team of neuroscientists at the University of Cambridge in the United Kingdom identified five broad phases of brain structure over the course of an average human life. These eras occur as the human brain rewires to support the different ways of thinking while we grow, mature, and eventually decline. The five major turning points are detailed in a study published today in the journal Nature Communications.Age 66–Early aging begins
This mid-60s turning point marks the start of an “early aging” phase of brain architecture. It’s a more mild period and is not defined by any major structural shifts. However, the team still uncovered meaningful changes to the pattern of brain networks on average at around age 66.“The data suggest that a gradual reorganisation of brain networks culminates in the mid-sixties,” said Mousley. “This is probably related to aging, with further reduced connectivity as white matter starts to degenerate. This is an age when people face increased risk for a variety of health conditions that can affect the brain, such as hypertension.”
