A concussion is the most common type of traumatic brain injury. It typically occurs after the head strikes some object, though concussions can be caused by whiplash. In most cases, the brain does not suffer any actual structural damage, but blood vessels may be stretched and some cranial nerves may be damaged. A concussion may be followed by brief unconsciousness, memory loss, depression, diffuculty concentrating and loss of balance due to brain injury.
Grades of Concussions
There are five grades of concussions:
- Grade I is characterized only by confusion
- Grade II involves confusion and anterograde amnesia (sometimes called short-term memory loss) lasting up to five minutes
- Grade III involves all of the characteristics of Grade II, as well as unconsciousness lasting up to five minutes and an inability to remember events that occurred just prior to the concussion (also called retrograde amnesia)
- Grade IV is characterized by all of the symptoms of Grade III, but unconsciousness can last up to 10 minutes
- Grade V is characterized by all of the symptoms of Grade IV, but unconsciousness can last up to twenty-five minutes
Depending on the severity of the trauma, post concussion symptoms may last up to a few weeks. Complete recovery may occur in a few months or may take several years.
Brain Injury Lawsuits
Concussions are most commonly the result of an car crash, tractor trailer collision or similar accident. When an individual suffers a concussion or other brain injury due to another's negligence or recklessness (i.e. driving while intoxicated), they may be able to file a brain injury lawsuit to recover any related damages. Lost wages, medical expenses and pain and suffering are among the brain injury damages available to concussion victims.
