Concussion symptoms may vary based on the type, severity and location of the head injury. [2] Concussion symptoms in infants, children, and adolescents often appear immediately after the injury, however, some symptoms may arise multiple days following the injury leading to a concussion. [3]
A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
Fatigue is the most frequently affirmed symptom of PCS included on the questionnaire, while double vision is the least affirmed.

Second-impact syndrome (SIS) occurs when the brain swells rapidly, and catastrophically, after a person has a second concussion before symptoms from an earlier one have subsided. This second blow may occur minutes, days, or weeks after an initial concussion, [1] and even the mildest grade of concussion can lead to second impact syndrome. [2]
