You can never know too much information (TMI) regarding traumatic brain injuries (TBI). Whether you’re learning about preventing TBIs or talking with your doctor about symptoms of a head injury, the more information, the better you can prevent and identify one.
What is a TBI?
This is a type of brain injury caused by a blow or jolt to, or penetration of, the head. A TBI can occur during a car accident, from being tackled during a football game, or a fall. After a TBI, nerve cells in the brain may be damaged, impacting the central nervous system. The neurons may have trouble doing their job carrying signals to different parts of the brain.
Not all head injuries are TBIs; a head injury can be mild or severe. Symptoms can range from a headache to loss of consciousness. If a head injury does not affect the brain, it is considered a minor head injury. Mild TBIs are commonly known as concussions. Knowing the symptoms of a TBI can help you identify when it’s time to go to the hospital emergency department.
Symptoms of a TBI
Traumatic brain injuries can cause a variety of symptoms depending on the severity and location of the injury. Sometimes, the symptoms may not show up right away. Your healthcare provider will ask you questions about how the injury occurred and which symptoms you are experiencing, including:
- Loss of consciousness
- Difficulty concentrating or thinking
- Memory loss
- Mood or personality changes
- Nausea or vomiting
- Change in sleep patterns
- Trouble waking
- Coordination problems
- Weakness or numbness in the arms or legs
