What is a concussion?

A concussion is defined as a brain injury that results from a blow to the head or a sudden jolt that causes the brain to move within the skull. This movement can lead to temporary disruption of brain function, which can manifest in various symptoms such as confusion, memory loss, headaches, dizziness, and balance problems. Understanding that a concussion is a type of brain injury is crucial, as it highlights the need for proper assessment and management to prevent further injury and allow for appropriate recovery.

In contrast, options that refer to a bruise on the skin, a mild headache, or a feeling of dizziness do not accurately capture the nature of a concussion. These may be symptoms or experiences related to various conditions or injuries, but they do not encompass the specific definition of a concussion as a significant brain injury. This distinction is important for recognizing the severity and implications of a concussion in terms of health and safety.
