What happens if you get a double concussion?
Second impact syndrome (SIS) occurs when two concussions happen in a relatively short period of time and the second concussion is inflicted before the first has fully healed. This causes the brain to “lose its ability to self-regulate pressure and blood volume flowing” and causes rapid and severe brain swelling.
What are the signs and symptoms of a concussion?

The mechanism of injury involves either a direct blow to the head or forces elsewhere on the body that are transmitted to the head. This is believed to result in neuron dysfunction, as there is increased glucose requirements but not enough blood supply.
A concussion can affect the frontal lobe by impairing judgment, impacting attention span and organization. Dysregulation to the frontal lobe caused by concussions or other brain injuries can result in loss of motivation and irrational or impulsive behavior.
Second impact syndrome. Rarely, experiencing a second concussion before signs and symptoms of a first concussion have resolved may result in rapid and usually fatal brain swelling. Concussion changes the levels of brain chemicals. It usually takes about a week for these levels to stabilize again,…

In the couple of weeks following a head injury, watch out for the symptoms of concussion, including headache, difficulty concentrating, and confusion. “That means it’s not healed yet,” Benzel says.
