What stage are you in?
Stage 1: The Brain Energy Crisis
Immediately after a concussion, brain cells go through a temporary energy imbalance.
The brain suddenly needs more energy to function, but for a period of time it has less ability to produce that energy efficiently.
This makes the brain more sensitive to stimulation.
Common symptoms during this phase include:
โข Headache
โข Brain fog
โข Light or sound sensitivity
โข Fatigue
โข Difficulty concentrating
โข Feeling overwhelmed in busy environments
During this stage, the brain benefits from:
โข Relative rest
โข Reduced stimulation
โข Gradual return to activity
As the brainโs energy system stabilizes, many symptoms begin to improve.

Stage 2: The Brain Alarm System
When the brain is injured, it activates protective systems.
It becomes more sensitive to things like:
โข Bright lights
โข Loud sounds
โข Movement
โข Thinking and multitasking
โข Busy environments
This is the brain trying to protect itself while it heals.
For some people, this alarm system settles down quickly.
For others, the brain can remain extra sensitive for a period of time, similar to a smoke alarm that keeps ringing after the smoke has cleared.
This does not mean the brain is permanently damaged. It means the brain is being overly protective.

Stage 3: Retraining the Brain
The brain is highly adaptable and capable of recovery.
If the brain has become overly sensitive, recovery involves gradually retraining it to feel safe again.
This may include:
โข Gradual return to physical activity
โข Step-by-step return to cognitive tasks
โข Vestibular or visual rehabilitation
โข Nervous system regulation strategies
โข Brain training approaches such as neurofeedback
As the brain relearns that normal activities are safe, the alarm system begins to calm down and symptoms improve.
