What Is a Concussion?
A concussion is a mild traumatic brain injury caused by a blow, jolt, or force that makes the brain move inside the skull. A concussion can affect thinking, balance, vision, mood, sleep, and physical comfort. Symptoms may appear immediately or develop later, and the injury can occur without loss of consciousness.

How Concussion Works

Concussion occurs when sudden force disrupts normal brain function. The force may come from a vehicle collision, a fall, or contact with another object. The brain does not need to strike a surface directly for symptoms to develop.

Assessment focuses on changes in function, not on a single symptom. A clinician may ask about memory, attention, balance, vision, headache, nausea, sleep, and mood. Symptoms can overlap with neck strain, whiplash, or other injuries, so the full accident history helps place the findings in context.
Post-Concussion Syndrome describes symptoms that continue after the initial injury. The Vestibular System may also be involved when dizziness, balance changes, or motion sensitivity follow an accident.

From the Arrowhead Clinic Chiropractor Marietta team
When we assess concussion concerns after an auto accident, we review the reported force, symptom pattern, and changes in daily function. We also consider related neck, balance, and movement findings. Our team documents these details so the care plan reflects the person’s overall injury picture.
Concussion in Practice: A Real-World Example
After a rear-end collision, a driver may report headache, slowed concentration, and dizziness when turning the head. The clinical assessment considers those symptoms alongside possible neck strain and changes in balance.
