Adolescence Lasts Into 30s - New Study Shows Four Pivotal Ages For Your Brain

The brain goes through five distinct phases in life, with key turning points at ages nine, 32, 66 and 83, scientists have revealed. From a report: Around 4,000 people up to the age of 90 had scans to reveal the connections between their brain cells. Researchers at the University of Cambridge showed that the brain stays in the adolescent phase until our early thirties when we "peak." They say the results could help us understand why the risk of mental health disorders and dementia varies through life. The brain is constantly changing in response to new knowledge and experience -- but the research shows this is not one smooth pattern from birth to death.

Some people will reach these landmarks earlier or later than others -- but the researchers said it was striking how clearly these ages stood out in the data. These patterns have only now been revealed due to the quantity of brain scans available in the study, which was published in the journal Nature Communications.
