Concussion is a 2013 American drama film written and directed by Stacie Passon and starring Robin Weigert. Although not autobiographical, the story was partially inspired by Passon herself suffering a mild concussion, in the same manner depicted in the film, shortly before she began writing the screenplay.

Concussion, from the Latin concutere ("to shake violently") or concussus ("action of striking together"), is the most common type of traumatic brain injury. The terms mild brain injury, mild traumatic brain injury (MTBI), mild head injury (MHI), minor head trauma, and concussion may be used interchangeably, although the last is often treated as a narrower category. Although the term "concussion" is still used in sports literature as interchangeable with "MHI" or "MTBI", the general clinical medical literature now uses "MTBI" instead. In this article, "concussion" and "MTBI" are used interchangeably. Frequently defined as a head injury with a temporary loss of brain function, concussion causes a variety of physical, cognitive, and emotional symptoms, which may not be recognized if subtle.
Treatment involves monitoring as well as physical and cognitive rest (reduction of such activities as school work, playing video games and text messaging). Symptoms usually resolve within three weeks, though they may persist or complications may occur.
Those who have had one concussion seem more susceptible to another, especially if the new injury occurs before symptoms from the previous concussion have completely resolved. There is also a negative progressive process in which smaller impacts cause the same symptom severity. Repeated concussions may increase the risk in later life for dementia, Parkinson's disease, and/or depression.
A variety of signs accompany concussion including somatic (such as headache), cognitive (such as feeling in a fog), emotional (such as emotional changeability), physical signs (such as loss of consciousness or amnesia), behavioral changes (such as irritability), cognitive impairment (such as slowed reaction times), and/or sleep disturbances. Fewer than 10% of sports-related concussions among children are associated with loss of consciousness.
Due to varying definitions and possible underreporting, the rate at which concussion occurs annually is not accurately known, but is estimated to be more than 6 per 1,000 people. Common causes include sports injuries, bicycle accidents, car accidents, and falls, the latter two being the most frequent causes among adults. In addition to a blow to the head, concussion may be caused by acceleration forces without a direct impact, and on the battlefield, MTBI is a potential consequence of nearby explosions.
It is not clear exactly what damage is done and how the symptoms are caused, but stretching of axons and changes in ion channels are involved. Cellular damage has reportedly been found in concussed brains, but it may have been due to artifacts from the studies. It is currently thought that structural and neuropsychiatric factors may both be responsible for the effects of concussion.
Concussion is a 2015 American biographical sports drama thriller film directed and written by Peter Landesman, and produced by Ridley Scott, Giannina Scott, David Woltroff, Larry Shuman, and Elizabeth Cantillon, based on the exposé "Game Brain" by Jeanne Marie Laskas, published in 2009 by GQ magazine.
Set in 2002, the film stars Will Smith as Dr. Bennet Omalu, a Nigerian forensic pathologist who fights against the National Football League to suppress his research on chronic traumatic encephalopathy (CTE) brain degeneration suffered by professional football players. It also stars Alec Baldwin, Gugu Mbatha-Raw, and Albert Brooks.
Columbia Pictures released the film on December 25, 2015. The film has received mixed reviews since its release, becoming a box office disappointment by grossing only $48.6 million of its $57 million budget.
