What are common symptoms of a concussion?

The selection highlighting headache, confusion, and dizziness reflects common symptoms of a concussion, which result from a traumatic brain injury. After a blow to the head or body that shakes the brain inside the skull, individuals often experience these symptoms as part of the body’s response to the injury.

Headaches often occur due to the brain's reaction to trauma, and confusion can stem from the disruption of normal brain function. Dizziness is also common because of the impact on the vestibular system, which affects balance and spatial orientation. Together, these symptoms are indicative of the neurological changes that occur during a concussion and help in assessing the severity and implications of the injury.

In contrast, localized pain and swelling are more typically associated with physical injuries rather than concussions, which directly affect brain function. While excessive fatigue can indirectly occur due to a concussion, it is not one of the hallmark symptoms. Temperature fluctuations and appetite changes can arise from various health issues, but they do not specifically pinpoint a concussion either.
