Your Brain Has Stages

Despite all our efforts to study the human brain, it remains a complex and mysterious organ. The good news is, scientists use that as motivation, and new studies are constantly revealing more information that helps us to understand our brains better. The latest study is out of Cambridge University where neuroscientists looked at MRI diffusion scans of nearly 4,000 people ranging from birth to age 90. In a nutshell, their findings were that your brain doesn’t just gradually change. In reality, your brain has stages.

Specifically, the brain moves through five distinct structural periods of time or epochs. These epochs are separated by four specific, major turning points where the brain rewires itself to meet the demands of life. Their findings change the field of understanding when it comes to our brain. Knowing that the brain develops in these stages, the question becomes: Are we supporting the brain, and the nervous system that feeds it, at every stage of life? And that’s where your healthcare choices come in.

The 100 Year Lifestyle Perspective

At The 100 Year Lifestyle we have always known that the brain and body are inseparable, connected through the nervous system. Your spine isn’t just scaffolding, it’s neurological infrastructure. As your brain wiring changes, for whatever reason or to meet whatever purpose, that change is communicated to the rest of the body through your spine and nervous system.

Chiropractic care is about optimizing that communication as a proactive strategy for health, adaptability, and longevity. Let’s take a look at what these newly identified brain stages are and how chiropractic care can help you be your best at every stage.

Stage 1: Childhood (Birth to 9 Years)

From the moment we’re born the brain begins to produce neural connections, then refines them through a process neuroscientists call network consolidation. Memories and learning paths are created as the most active neural connections survive while the rest are trimmed away. This creates a period of rapid growth, learning, coordination, and sensory development.

From a chiropractic perspective, this stage matters because:

The nervous system is learning how to interpret the world
Posture, movement patterns, and coordination are being established
Early stressors, including physical, chemical, or emotional, can influence development

This is why chiropractic care during childhood is about supporting neurological organization by helping the brain and body consistently communicate clearly during one of the most critical wiring phases of life.

Stage 2: Adolescence (Ages 9 to 32)

Wow! This new research challenges the old idea that adolescence ends in the teens. Instead, it finds that based on brain architecture alone, adolescent wiring patterns extend into the early thirties.

This is the only stage where neural efficiency is actively increasing. That means that existing communication pathways are becoming faster, stronger, and more coordinated.

Additionally, it’s a time of:

Increased cognitive performance.
Challenges with emotional regulation
High risk-taking behavior
Vulnerable mental health

Chiropractic care during this stage supports:

Nervous system adaptability under stress
Good posture development during rapid physical change
Greater demands on brain–body coordination

The reality is, if the nervous system is overwhelmed or inefficient for any reason during this phase, it can interfere with how well the brain reaches its peak potential. Think about all our young athletes go through and you’ll have a peek into the bigger picture of potential problems during this stage.

Stage 3: Adulthood (Ages 32 to 66)

The longest brain epoch is adulthood. Generally, structurally speaking, the brain enters a period of relative stability, with fewer dramatic shifts. But stability doesn’t mean immunity. This is the time when lifestyle choices, stress, posture, movement (or lack thereof), and spinal health together determine how well the brain will transition into later stages.

As a very young chiropractor, my experience with Max taught me that if you’re still breathing chiropractic care can help. That said, chiropractic care is about protecting neurological resilience by keeping communication clear so the brain can stay adaptable rather than becoming rigid. That’s much more effective as prevention than after-the-fact trying to fix things. In 100 Year Lifestyle terms, this is where prevention pays its biggest dividends.

Stage 4: Early Aging (Around Age 66)

In relation to the other stages, this stage isn’t terribly dramatic, but it’s totally meaningful. The Cambridge researchers observed at this stage a gradual reorganization of brain networks and reduced connectivity, often coinciding with increased health risks like hypertension. It’s a time when small inefficiencies become amplified.

Chiropractic care during early aging focuses on:

Supporting spinal mobility and neurological flow
Reducing unnecessary stress on the nervous system
Helping the brain adapt to change instead of accelerating decline

A nervous system under less stress is better equipped to age well, and we all know it.

Stage 5: Late Aging (Around Age 83+)

In this final brain epoch, global brain connectivity declines and the brain relies more heavily on specific regions of the brain. That’s not to stay the brain stops working. It’s to say it works differently. From a chiropractic standpoint, this stage reinforces a lifelong truth that the more efficiently the nervous system has been supported across the decades, the more reserve the brain has when connectivity naturally decreases. In other words, if you’ve been taking care all along, then you’ve banked the neurological clarity you need for that rainy day.

The 100 Year Lifestyle Takeaway

This new research confirms something chiropractors have long understood. The brain’s journey, like your health journey in general, is not linear. There are windows of vulnerability and opportunity throughout life and at every stage of your brain. Real holistic health care, like chiropractic care, isn’t about chasing symptoms at those turning points. It’s about supporting the nervous system throughout your life— before, during, and after the stages. Now that you know that your brain was designed to adapt, connect, and thrive at every stage of life, don’t you agree?
