A concussion is a form of a mild traumatic brain injury (TBI). This injury is a result due to a blow to the head that could make the person's physical, cognitive, and emotional behaviors irregular. Symptoms may include clumsiness, [[Fatigue (medical)|fatigue]], [[confusion]], [[nausea]], [[Blurred vision|blurry vision]], [[headache]]s, and others.<ref>{{cite web|title=Concussion - Symptoms and causes|url=https://www.mayoclinic.org/diseases-conditions/concussion/symptoms-causes/syc-20355594|access-date=2020-10-16|website=Mayo Clinic|language=en}}</ref> Mild concussions are associated with [[sequela]]e.<ref>{{cite journal | vauthors = Rao V, Syeda A, Roy D, Peters ME, Vaishnavi S | title = Neuropsychiatric aspects of concussion: acute and chronic sequelae | journal = Concussion | volume = 2 | issue = 1 | pages = CNC29 | date = March 2017 | pmid = 30202570 | pmc = 6094361 | doi = 10.2217/cnc-2016-0018 }}</ref> Severity is measured using various [[concussion grading systems]].

A slightly greater injury is associated with both anterograde and retrograde [[amnesia]] (inability to remember events before or after the injury). The amount of time that the amnesia is present correlates with the severity of the injury. In all cases, the patients develop [[post concussion syndrome]], which includes memory problems, dizziness, tiredness, sickness and [[Major depressive disorder|depression]]. Cerebral [[concussion]] is the most common head injury seen in children.<ref name=":3">{{cite journal | vauthors = Arciniegas DB, Anderson CA, Topkoff J, McAllister TW | title = Mild traumatic brain injury: a neuropsychiatric approach to diagnosis, evaluation, and treatment | journal = Neuropsychiatric Disease and Treatment | volume = 1 | issue = 4 | pages = 311–27 | date = December 2005 | pmid = 18568112 | pmc = 2424119 }}</ref>
