🧠 Your brain doesn’t age gradually. It reorganizes in distinct phases with big shifts at ages 9, 32, 66, and 83.

1. Birth to ~9 — Early Wiring

• Brain connections are rapidly forming and being pruned.

• Networks aren’t efficient yet, they’re being shaped.

👉 Rapid pruning and structural growth. 

2. ~9 to ~32 — Rising Efficiency

• This is the only life phase where global efficiency actually increases.

• Networks become more integrated and efficient up to ~32.

• This is also the longest phase of growth in network organization.

👉 Efficiency peaks. 

3. ~32 to ~66 — Adult Plateau

• Around 32 is the biggest topological turning point in your brain’s wiring.

• After this, global efficiency stops rising. Networks stabilize and slowly start becoming more segregated.

👉 Peak efficiency, then plateau. 

4. ~66 to ~83 — Early Aging Shift

• Brain networks shift toward being less integrated, more modular.

• This matches increased vulnerability to age-related decline.

👉 White matter decline accelerates. 

5. ~83+ — Late Aging Epoch

• Last shift: connectivity patterns plateau and rely more on local/regional networks.

👉 Late-life reorganization, weaker global integration.

Key Takeaways for Brain Health

• You don’t just “decline” after peak.

• Each phase has different priorities: building, integrating, maintaining, compensating, resilience.

• Midlife interventions matter because you’re working from peak organization around age 32.

0–9: wiring foundation

9–32: efficiency up

32: peak

32–66: stable networks

66+: segregation

83+: local reliance

No fluff, just what the science shows:

• Data drawn from ~3,800+ diffusion MRI scans of people aged 0–90. 

• Brain network efficiency peaks around late 20s/early 30s (~29–32). 

• Turning points mark shifts in how the brain organizes, not just age.
