"concussion"の定義と意味

What is a "concussion"?

A concussion is a type of brain injury that occurs when the head experiences a sudden, forceful impact or rapid movement change. This can happen due to accidents, falls, or sports-related incidents. Concussions can cause various symptoms such as headache, dizziness, confusion, nausea, sensitivity to light or noise, and temporary loss of consciousness. While most concussions are mild and resolve on their own with rest, it is essential to seek medical attention for proper diagnosis and management, especially if symptoms worsen or persist. Recovery typically involves physical and mental rest until symptoms improve, followed by a gradual return to normal activities under medical supervision.
