A concussion is a minor or less severe type of brain injury, which may also be called a traumatic brain injury. A concussion can affect how the brain works for a awhile. It may lead to headaches, changes in alertness, or loss of consciousness. A concussion can result from a fall, sports activities, or car accidents. A big movement of the brain (called jarring) in any direction can cause a person to lose alertness (become unconscious).
Headaches are common in the first few days after a mild traumatic brain injury. If headaches are improving, you do not have to worry or seek urgent care. Headaches have several potential causes, and simply referring to all headaches after trauma as post traumatic headaches does not identify cause or treatment.ecause the symptoms after concussion are very similar to the symptoms that persist long after the injury, the distinction between concussion symptoms and PCS symptoms is often uncertain. The factors that extend symptoms-not just the injury severity-may need to be identified for proper treatment.
