Concussion

Excerpt

A concussion is a “traumatically induced transient disturbance of brain function.” Concussions are a subset of the neurologic injuries known as traumatic brain injuries. Traumatic brain injuries have varying severity, ranging from mild, transient symptoms to extended periods of altered consciousness. Given the usually self-limited nature of symptoms associated with a concussion, the term mild traumatic brain injury (mTBI) is often used interchangeably to refer to a concussion. However, concussions are technically a subset of mTBIs. The prognosis is usually good, and most patients experience complete resolution of symptoms.
