Grade 3
This type of concussion involves unconsciousness and lasting presence of the aforementioned symptoms. Treatment and observation are required immediately as a Grade 3 concussion can signal mild brain damage or even brief comas. The effects of a Grade 3 concussion can last for weeks.
Symptoms: A Grade 3 concussion will feature brief unconsciousness that can last mere seconds to as many as five minutes. In serious cases, amnesia can set in for more than a day, in addition to more extreme cases of the aforementioned symptoms. People suffering from Grade 3 concussions can suffer from intense confusion and be found often repeating themselves, be prone to vacant staring and be slow to respond in basic conversation or movement.
Treatment: As with a Grade 2 concussion, observation is essential to a Grade 3, however immediate medical attention is required. Should the symptoms worsen in any manner (i.e. more frequent headaches, slurred speech, decreased motor skills, etc.) further medical attention will be required as there could be early signs of brain damage. Additionally, it is important to monitor the victim’s vision and eye coordination after a Grade 3 concussion, as differing pupil sizes are a telltale indicator or brain damage.
Prevention: Concussions often go undiagnosed or ignored as headaches, so it is important that caution is used when participating in any competitive sports, operating an automobile or working at home or work with heavy machinery or tools.
