Term
Concussion
Definition
alteration of mental status due to biomechanical forces affecting the brain. A concussion may or may not cause loss of consciousness.
Term
Primary mechanisms/forces that can lead to concussion
Definition
Linear - Example: A quarterback falls to the ground and hits the back of his head. The falling motion propels the brain in a straight line downward.
Rotational - Example: When a football player is tackled, his head may strike an opponent’s knee; this contact to the head can cause a rotational motion.
Term
Immediate Signs of Concussion
Definition
Impaired attention -- vacant stare, delayed responses, inability to focus
Slurred or incoherent speech
Gross incoordination
Disorientation
Emotional reactions out of proportion
Memory deficits
Any loss of consciousness
Term
Post Signs of Concussion
Definition
Persistent headache
Dizziness/vertigo
Poor attention and concentration
Memory dysfunction
Nausea or vomiting
Fatigue easily
Irritability
Intolerance of bright lights
Intolerance of loud noises
Anxiety and/or depression
Sleep disturbances
Term
Second Impact Syndrome
Definition
Second concussion occurs while still symptomatic & healing from previous injury days or weeks earlier

Second impact more likely to cause brain swelling and other widespread damage
Can be fatal -- 50% mortality rate in most severe cases
Term
Grade 1 Concussion
Definition
Transient confusion
NO loss of consciousness
Concussion symptoms or mental status abnormalities resolve in less than 15 minutes
Management: Remove from contest
Examine immediately and at 5-minute intervals for the development of mental status abnormalities or post-concussive syndrome at rest and with exertion
May return to contest if mental status abnormalities or post-concussive symptoms clear within 15 minutes

When to return:15 minutes or less , multiples (1 week)
Term
Grade 2 Concussion
Definition
Transient confusion
NO loss of consciousness
Concussion symptoms or mental status abnormalities last more than 15 minutes
Managaement:
-Remove from contest; disallow return that day
-Examine on-site frequently for signs of evolving intracranial pathology
-A trained person should reexamine the athlete the following day
-A physician should perform a neurologic exam to clear the athlete for return to play after 1 full asymptomatic week at rest and with exertion

When to return:1 wk, mutilpes-2 weeks
Term
Grade 3 Concussion
Definition
Any loss of consciousness, either brief (seconds) or prolonged (minutes)

Management: Transport from the field to the nearest emergency department by ambulance if still unconscious or worrisome signs are detected (with cervical spine immobilization, if indicated)
A thorough neurologic evaluation should be performed emergently, including neuroimaging procedures when indicated
Admit to hospital if any signs of pathology are detected or if the mental status remains abnormal

When to return:out for 2 weeks, multiples (month or longer)
