What is a concussion?
A concussion is a mild traumatic brain injury caused by a bump, blow, or jolt to the head or body that disrupts normal brain function.
What Happens During a Concussion?
Why Do Some People Experience Symptoms for a Long Period of Time?
- Most people recover from a concussion within 1–6 weeks.
- Some individuals experience symptoms that persist for months or longer.
- Symptoms that continue beyond the expected recovery period may be referred to as Post-Concussion Syndrome (PCS).
Recovery time varies from person to person. Factors such as age, injury severity, concussion history, and overall health may influence how quickly someone recovers. While most people recover fully, some individuals require additional medical support and rehabilitation.
Why Do Symptoms Occur?
During a concussion, the rapid movement of the brain can stretch and strain nerve fibers called axons. These fibers help different parts of the brain communicate with one another.
When communication between brain cells is disrupted, symptoms such as headaches, dizziness, memory problems, difficulty concentrating, sleep disturbances, and mood changes may occur.
