When it comes to concussions, a five-grade system is utilized in order to classify the severity of a particular concussion. It is vital to note that concussions categorized as a mild case still carry the risk of permanent neurological damage. With this in mind, it is important to consult a doctor if the individual sustained any kind of head injury for proper assessment and treatment.
What is a Grade I concussion?
A Grade I concussion is considered as the least severe type and this does not involve loss of consciousness. In reality, the only noticeable symptom of this type of concussion is mild confusion or disorientation that typically subsides within 15 minutes or less. On the other hand, an individual who sustained a Grade I concussion should avoid any physical activity and must observe for lingering symptoms a few days after the injury was sustained.
Grade II concussion
In a Grade II concussion, the individual will not lose consciousness completely and usually experience anterograde amnesia. This type of amnesia involves difficulty recalling the events that occurred moments after the initial impact. Always remember that anterograde amnesia must disappear within five minutes. If the amnesia tends to lasts longer, it clearly indicates that the individual sustained a severe injury to the head.
Grade III concussion
In severe head injuries, they can be classified as a Grade III concussion that is characterized by a period of unconsciousness that can last for five minutes or less along with symptoms of a Grade I or Grade II concussion. An individual who sustained a Grade III injury or higher must be stabilized as part of the first aid care and should stay immobile until the medical team arrives on the scene.
Grade IV concussion
If the individual is diagnosed with a Grade IV concussion, it is best to seek immediate medical attention. Always bear in mind that this classification is similar to the Grade III injury. The only difference is the period of unconsciousness can last up to ten minutes. This type of concussion carries a high risk of severe lingering effects and even the possibility of leading to permanent brain damage.
Grade V concussion
The most serious type of injury is categorized as Grade V. The distinguishing feature of this injury is the extended period of unconsciousness that lasts longer than 10 minutes. In this type of injury, all of the symptoms will surely persist for days, weeks or even months. The symptoms include headache, dizziness, nausea and vomiting as well as cognitive, memory and emotional problems.
Important considerations to bear in mind
In case the symptoms of an acute concussion last more than 15 minutes, it is best to consult a doctor right away or call for emergency assistance. Even if a head injury appears minor, it is still advisable to have the injury assessed by a doctor.
