Your Brain Changes in Stages as You Age, Study Finds
Study of 3,800 MRI scans reveals brain rewiring at ages 9, 32, 66, and 83 with implications for understanding mental health disorder onset, researchers said.
- HealthDay and others reported this week that researchers found human brains undergo four major turning points shaping thinking, learning, and connection.
- Using pooled MRI data from about 3,800 people, researchers applied diffusion-tracking scans to map brain connectivity from newborns to age 90.
- Stage-by-Stage, the scans reveal: rapid gray and white matter growth from birth to age 9, extended rewiring ages 9–32, stabilization ages 32–66, independence ages 66–83, and decline after 83.
- The staged model overlaps with typical diagnosis ages for mental disorders, and researchers say these phases shape cognition and emotion while raising questions about vulnerability in the second life stage.
- Outside researchers called the work ambitious but noted data limits, praising the study while cautioning that pooling nine different data sets may introduce bias and more study is needed.

Study maps brain wiring differences in youth with autism
Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have uncovered new insights into how brain wiring differs in children and young adults with autism, pointing to more precise ways of understanding the condition.
