Concussion: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

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.

Concussion: Causes
(Handbook of Diseases)

The blow that causes a concussion is usually sudden and forceful — a fall to the ground, a punch to the head, a motor vehicle accident. Also, such a blow sometimes results from child abuse. Whatever the cause, the resulting injury is mild compared with the damage done by cerebral contusions or lacerations.

Concussion: Concussion - pathophysiology
(The 5-Minute Pediatric Consult)

  • The brain is buoyed in the cranium by CSF that acts as protective insulation. In acceleration-deceleration accidents the brain continues to experience forward momentum and slams against hard bone. The temporal and frontal lobes of the brain are particularly prone to injury because of their location adjacent to irregular parts of the skull.
  • Depressed level of consciousness is thought to be the result of rotational stretch injury to the reticular activating system in the dorsal aspect of the brain stem.
  • Changes after concussion include changes in neuronal depolarization and neurotransmitter release, impaired axonal function, and altered brain autoregulation and glucose metabolism.
  • Children may respond to brain trauma differently than adults due to developmental factors such as brain size, brain water content, myelination level, skull and suture geometry and elasticity, and differential skull to body proportions.
