Traumatic brain injuries (TBIs) are some of the most complex — and most devastating — wounds that car accident victims can suffer. The brain damage can lead to physical and mental disabilities that last a lifetime.

However, not all TBIs are alike. Doctors classify them in the following ways:

Mild TBIs

Often called “concussions,” mild TBIs can be so subtle that many people don’t even immediately realize that they’ve been seriously hurt. If there’s any loss of consciousness, it may last only a few seconds — minutes, at most. These kinds of brain injuries are “silent,” in that they cannot be detected on normal imaging tests, but victims still may suffer from headaches, nausea, fatigue and confusion for a time.

Moderate TBIs

A moderate TBI will cause the victim to lose consciousness for up to 24 hours and victims may not have any clear memory of events for a day or so after the accident. Some damage to the brain can be seen on imaging tests. It isn’t uncommon for victims to experience cognitive issues, including memory loss, processing disorders, depression and seizures.

Severe TBIs

These are likely to have a widespread effect on the victim’s physical and intellectual abilities. The brain damage is highly visible through imaging tests and victims usually lose consciousness for more than a day. Some victims may not even survive.

If your loved one suffered a TBI due to another person’s negligent or reckless driving, no amount of money can restore what has been lost — but it can provide the money you need to see to their care and your family’s future.
