Why Do Concussion Symptoms Sometimes Persist?
Most people expect concussion symptoms to resolve within a few weeks.
But many patients experience dizziness, headaches, fatigue, brain fog, or visual sensitivity that continue for months.
When that happens, people are often told:
• “Everything looks normal.”
• “You just need more time.”
• “Try to reduce stress.”
In reality, persistent concussion symptoms often occur because one or more neurologic systems has not yet fully reintegrated after injury.
The brain must coordinate several systems simultaneously:
• vision
• vestibular (balance)
• body position and movement
• autonomic regulation
When one of these systems becomes the primary constraint, the brain works harder to stabilize the mismatch, increasing energy demand at a time when concussion has already reduced metabolic efficiency.
We wrote a guide explaining:
• why symptoms sometimes persist
• how these neurologic systems interact
• what evaluation should focus on during recovery
