What Happens To The Brain When Someone Gets A Concussion
Brain cells injured: Concussions, a form of mild traumatic brain injury (tbi), are usually caused by a blow to the head which causes the brain to move within the skull. The force of the brain moving suddenly, often bumping the skull, causes chemicals to leak out of the brain cells. It is important to rest to allow the brain to repair the damage to these delicate cells. www.cdc.gov/concussion/. ...Read moreSee 2 more doctor answers

Brain chemistry: After a concussion, the common symptoms include headache, difficulty with concentration, memory problems, increased irritability. It is known that there is a change in the brain metabolism. The neurons are thus much more sensitive to insults. This is why patients with a concussion are more susceptible to a head injury (the second impact syndrome). ...Read more

Below: The best explanation is from a Mayo Clinic site: What is a traumatic brain injury? TBI is an injury to the brain caused by a blow or jolt to the head from blunt or penetrating trauma. The injury that occurs at the moment of impact is known as the primary injury. Primary injuries can involve a specific lobe of the brain or can involve the entire brain. Sometimes the skull may be fractured, but not always. During the impact of an accident, the brain crashes back and forth inside the skull causing bruising, bleeding, and tearing of nerve fibers (Fig. 1). Immediately after the accident the person may be confused, not remember what happened, have blurry vision and dizziness, or lose consciousness. At first the person may appear fine, but their condition can decline rapidly. After the initial impact occurs, the brain undergoes a delayed trauma – it swells – pushing itself against the skull and reducing the flow of oxygen-rich blood. This is called secondary injury, which is often more damaging than the primary injury. ...Read more
Back: Symptoms that take longer to recover likely represents a "worst injury". This is seen when the back of the brain is affected, possibly from a fall on the back of the head. The symptoms that are typically predictive of a prolonged recovery are balance issues, fogginess, neck pain, and difficulty concentrating. ...Read more
Not clear: The actual changes in the brain after a concussion are not properly understood. After concussion, post-concussive syndrome (pcs) can be from mild to severe. It can include a range of symptoms including (but not limited to) headaches, dizziness, nausea, poor concentration, irritability, anxiety, noise or light sensitivity, depression, fatigue, sleep problems, memory problems. ...Read moreSee 1 more doctor answer
Yes: See: http://www.sportsconcussion.co.za/Research/Pathophysiology/2013/The%20Molecular%20Pathophysiology%20of%20Concussive%20Brain%20Injury.pdf Chronic traumatic encephalopathy can likely come about with many micro traumas. Our improving imaging tests (eg tractography) show this problem to be more evident. CT and even conventional MRI are blunt instruments and could be negative. ...Read more
