Concussion, from the Latinconcutere ("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.
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.
Abby Ableman is a lesbian who becomes disillusioned with her domestic life and career after suffering a mild concussion when her son, Jake, accidentally hits her in the head with a thrown baseball. She then begins working as a prostitute for other women.
