What Is Traumatic Brain Injury?
What is traumatic brain injury (TBI)? Traumatic brain injury (TBI) is a sudden injury that causes damage to the brain. It may happen when there is a blow, bump, or jolt to the head. This is a closed head injury. A TBI can also happen when an object penetrates the skull. This is a penetrating injury. Symptoms of a TBI can be mild, moderate, or severe. Concussions are a type of mild TBI. The effects of a concussion can sometimes be serious, but most people completely recover in time. More severe TBI can lead to serious physical and psychological symptoms, coma , and even death.
Pathophysiology, Underlying Causes & Clinical Presentation
In Traumatic Brain Injury (S09.90XA), physiological disruption stems from conditioned fear-extinction deficits [Traumatic Brain Injury S09.90XA], Cross-referenced with NIH MeSH (Brain Injuries, Traumatic), informing Anxiety, OCD & Trauma Disorders protocols that track Resting Heart Rate in Traumatic Brain Injury (S09.90XA: Variability (HRV)) (Stable upward personal trend (S09.90XA)).
Common Symptoms & Clinical Signs
- • Some of the common causes of a closed head injury include • Falls . This is the most common cause in adults age 65 and older
- • Motor vehicle crashes. This is the most common cause in young adults
- • Presentation of Traumatic Brain Injury (S09.90XA): avoidance of triggers, in Traumatic Brain Injury (S09.90XA: intrusive trauma memories,)
- • Secondary Traumatic Brain Injury clinical sign: excessive, hard-to-control anticipatory in Traumatic Brain Injury (S09.90XA: worry or intrusive)
