concussion

noun    (Concise Encyclopedia)

Period of nervous-function impairment that results from relatively mild brain injury, often with no bleeding in the cerebral cortex. It causes brief unconsciousness, followed by mental confusion and physical difficulties. These effects usually clear up within hours, but in some cases disturbance of consciousness continues, and there may be residual symptoms. Some level of amnesia often accompanies concussion. Recovery from concussion is almost always complete unless more serious injury, such as skull fracture, accompanies it.
