You know, Jay, there are several different types of TBI. Traumatic brain injury can be classified as mild, moderate or severe. Let’s take a closer look at mild TBI, which is often referred to as mTBI, or concussion. With a mild traumatic brain injury there is sometimes a brief loss of consciousness or a feeling of “having your bell rung” after a head trauma. Lab tests and scans are usually normal; however, personality, memory, physical abilities, or other functions can be affected.
Mild TBI, or concussion, can cause a loss of consciousness, called LOC, loss of memory, or confusion. Thinking may become slow and disorganized, memory can become unreliable, and concentration often becomes difficult. The injury blocks the pathways normally used by the brain to send messages. When this trauma occurs, the brain is not able to continue normal function and so it shuts down.
This “shut down” can be either complete, which causes unconsciousness, or partial, which has been described as a “dazed” feeling. Keep in mind that a loss of consciousness is not required for an injury to be considered a concussion, or mild TBI.
Specific factors for diagnosing mild TBI include:
In most mild TBI cases, the patient will recover completely. In a small number of cases, the symptoms can last a long time and cause permanent changes to the patient’s life, for example in areas, such as personality and memory.
