Head traumas and concussions during an auto accident are a very real risk.... even if no direct impact to the head occurred. There are many physical and cognitive changes that can occur when someone is suffering from a concussion (also known as a mild traumatic brain injury). If you have been involved in an auto accident, make sure you are assessed immediately to rule out any possibility of post-concussive syndrome. Symptoms may be immediately evident, such as an immediate headache, dizziness, balance problems, or vertigo and nausea. Other symptoms may take days or even up to 2 weeks to become evident. The following is a list of the three levels of head trauma and post-concussive syndrome.
Grade 1 / First Degree Concussion
• No actual loss of consciousness.
• Blurring of consciousness lasting less than 10-20 seconds. Minimal or no signs are present.
• The only neurologic deficit is a brief period of post-traumatic amnesia lasting less than 30 minutes.
• EEG, CT or MRI are usually not necessary after a mild concussion. If post-concussion syndrome occurs these studies should be done.
Grade 2 / Second Degree Concussion:
• Blurring or loss of consciousness lasting 20 seconds to 1-2 minutes. Minimal to moderate symptoms and signs are present.
• Will rarely occur without a loss of consciousness. Typically there will be a protracted period of post-traumatic amnesia lasting over 30 minutes and less than 24 hours.
• Generally overnight admission for observation and CT scan if necessary.
Grade 3 / Third Degree Concussion:
• Loss of consciousness lasting more than five minutes.
There will be loss of consciousness with a sustained period of post-traumatic amnesia lasting longer than 24 hours.
