Secondary Traumatic Stress (STS) impacts many individuals in the mental health field; as of 2013, the prevalence rates for STS amongst different professions is as follows: 15.2% among social workers, 16.3% in oncology staff, 19% in substance abuse counselors, 32.8% in emergency nurses, 34% in child protective services workers, and 39% in juvenile justice education workers.

Other factors in secondary damage are breakdown of the blood–brain barrier, edema, ischemia and hypoxia. [15] Ischemia is one of the leading causes of secondary brain damage after head trauma. [9] Similar mechanisms are involved in secondary injury after ischemia, trauma, and injuries resulting when a person does not get enough oxygen. [5]
Focal and diffuse brain injury are ways to classify brain injury: focal injury occurs in a specific location, while diffuse injury occurs over a more widespread area.It is common for both focal and diffuse damage to occur as a result of the same event; many traumatic brain injuries have aspects of both focal and diffuse injury.

While it was once thought that the main cause of axonal separation was tearing due to mechanical forces during the trauma event, it is now understood that axons are not typically torn upon impact; rather, secondary biochemical cascades, which occur in response to the primary injury (which occurs as the result of mechanical forces at the moment ...
Symptoms of brain injuries can also be influenced by the location of the injury and as a result impairments are specific to the part of the brain affected. Lesion size is correlated with severity, recovery, and comprehension. [4] Brain injuries often create impairment or disability that can vary greatly in severity.
TBI can also be characterized based on mechanism (closed or penetrating head injury) or other features (e.g., occurring in a specific location or over a widespread area). [6] Head injury is a broader category that may involve damage to other structures such as the scalp and skull.
A common symptom of PTA is confusion. The most prominent symptom of post-traumatic amnesia (PTA) is a loss of memory of the present time. [10] As a result, patients are often unaware of their condition and may behave as if they are going about their regular lives.
Secondary blast wounds may be lethal and therefore many anti-personnel explosive devices are designed to generate fast-flying fragments. Most casualties are caused by secondary injuries as shrapnels generally affect a larger area than the primary blast area , because debris can easily be propelled for hundreds or even thousands of meters.
