What is a common symptom of a concussion?

A common symptom of a concussion is a headache. Concussions, which are a form of mild traumatic brain injury, often lead to various symptoms as a result of the brain being jolted within the skull. Headaches can occur either as a result of the injury itself or due to other related factors, such as tension or stress.

While dizziness, nausea, and blurred vision are also symptoms associated with concussions, headaches are one of the most frequently reported experiences by individuals following a head injury. It's important to recognize that a concussion can present a range of symptoms, and individuals might experience one or several of these symptoms simultaneously. Thus, headaches serve as a hallmark symptom that helps in identifying a concussion in those who have sustained an impact to the head.
