Concussion: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

A concussion may produce vomiting and a short-term loss of consciousness. The patient may also suffer from anterograde and retrograde amnesia, in which the patient not only can’t recall what happened immediately after the injury, but also has difficulty recalling events that led up to the traumatic incident. The presence of anterograde amnesia and the duration of retrograde amnesia reliably correlate with the injury’s severity. The length of the unconsciousness may also relate to the concussion’s severity.

This type of injury commonly causes adults to be irritable or lethargic, to behave out of character, and to complain of dizziness, nausea, or severe headache. Some children have no apparent ill effects, but many grow lethargic and somnolent in a few hours. Postconcussion syndrome — characterized by headache, dizziness, vertigo, anxiety, and fatigue — may persist for several weeks after the injury.

Concussion: Signs and symptoms
(Handbook of Diseases)

Concussion may produce a short-term loss of consciousness, vomiting, and both anterograde and retrograde amnesia, in which the patient not only can’t recall what happened immediately after the injury but also has difficulty recalling events that led up to the traumatic incident. The presence of anterograde amnesia and the duration of retrograde amnesia reliably correlate with the severity of the injury.

Such an injury can cause an adult to be irritable or lethargic, to behave out of character, and to complain of dizziness, nausea, or severe headache. Some children have no apparent ill effects, but many grow lethargic and somnolent in a few hours.

Clinical tip  Although all of the above signs and symptoms occur normally with a concussion, they may also result from more serious head injuries. Medical evaluation is necessary to rule out serious injury to the brain.

Postconcussion syndrome — characterized by headache, dizziness, vertigo, anxiety, and fatigue — may persist for several weeks after the injury.
