16 MEDICAL BOOKS ONLINE! Review excerpts from medical books online, free, without registration, for more information about the prevalence and/or incidence of Concussion.
The blow that causes a concussion is usually sudden and forceful. It occurs when the head strikes a stationary object (as in a fall to the ground), or when a moving object strikes the head (as in a punch to the head). Such blows may also result from automobile accidents or child abuse. Significant jarring can lead to unconsciousness. Microscopic shearing of nerve fibers is thought to occur in the brain from sudden acceleration or deceleration from the head injury.
In 2001, death resulted in 5 of every 100,000 patients with trauma related to falls.

The term 'prevalence' of Concussion usually refers to the estimated population of people who are managing Concussion at any given time. The term 'incidence' of Concussion refers to the annual diagnosis rate, or the number of new cases of Concussion diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
