What symptoms may indicate a concussion?

The symptoms that indicate a concussion primarily involve changes in mental status and physical well-being following a head injury. Confusion, headache, dizziness, and nausea are classic signs that reflect the impact a concussion has on the brain's function and overall balance.

Confusion can manifest as difficulty remembering events immediately surrounding the injury or feeling dazed and disoriented. Headaches are common after concussions due to the trauma, and dizziness often indicates disrupted balance and coordination linked to brain injury. Nausea frequently accompanies these symptoms as a response to the brain's altered state and potential changes in vestibular functions.

In contrast, swelling and bruising may occur with other types of injuries but are not definitive indicators of concussion. Loss of appetite and increased energy levels are not typically associated with a concussion either. Therefore, the combination of confusion, headache, dizziness, and nausea distinctly points to a concussion, confirming it as an informed choice.
