In the context of concussions, which are a type of traumatic brain injury, it's important to distinguish symptoms that are commonly associated with this condition from those that are not. Symptoms such as headache, memory loss, and nausea are frequently reported by individuals who have suffered a concussion.

Headaches are one of the most common symptoms, often resulting from the injury itself or due to increasing intracranial pressure. Memory loss can occur, especially regarding events surrounding the injury; this is known as retrograde amnesia. Nausea and vomiting can also manifest, typically due to the brain's response to injury and changes in equilibrium.

On the other hand, paralysis is not a typical symptom of a concussion. While concussions can result in various neurological symptoms, paralysis usually indicates more severe brain injury or injury to the spinal cord, and is not characteristic of a concussion. This distinction is crucial in assessing the severity of an injury and determining the appropriate medical response.
