Answer:
A.
Explanation:
A concussion is a trauma-induced functional neurologic deficit.
Any force blow to the head or any body part which results in fast movement of the head can cause changes in the function's of one's brain. Concussion doesn't require a direct blow to the head, but any strong force that bumps the brain strong enough, that the hit can affect brain's function. Most people suffering from concussion won't lose consciousness.
If the person is suffering a heavy head concussion, they should be immediately transferred to the doctor's office for the further evaluation, CT or MRI scan. If a concussion is not that serious, a person should visit doctor in the next three days. And should be evaluated on the daily basis until they are recovered from the concussion, either by a professional athlete or doctor.
When the concussion is diagnosed by an experienced healthcare professional, they will determine the best way to treat it. A person must rest, not only physically, but cognitive rest from any daily activity must also be applied.
Athlete himself/herself might report some of the most common symptoms:
Pressure or headache, vomiting, problems with balance or dizziness, blurry or double vision, being sensitive to light or sounds, concentration or problems with memory, confusion, or simply not ''feeling right''.
Some of the symptoms that can be observed by parents, coaches etc:
A person appears stunned, they seem confused, forgetfulness, not being certain about the game and score, clumsy movements, answering and talking slowly, losing consciousness, changes in behavior and personality, memory loss and not being able to remember events before suffering a head trauma.
