severe TBI), and sources of data (e.g., hospital admissions, emergency room visits, general practitioner visits). These variations are often due to differences in participant characteristics (e.g., ages included), diagnostic classification criteria within and across subtypes (e.g., mild TBI vs. Incidence and prevalence rates of TBI vary across clinical and epidemiological studies. Current studies estimate that approximately 775,000 older adults live with long-term disability associated with TBI (Zaloshnja et al., 2008). TBI-related disability after hospitalization to be 3.2 million (Zaloshnja, Miller, Langlois, & Selassie, 2008). Additional data suggest the prevalence of U.S. This represents a prevalence of approximately 2% of the U.S. Whereas age-adjusted rates of TBI-related ED visits increased by 54% over the span of 8 years (2006–2014), hospitalization rates decreased by 8% and death rates decreased by 6% (CDC, 2014).Īccording to the National Center for Injury Prevention and Control, an estimated cumulative 5.3 million individuals are living with a TBI-related disability in the United States. These incidence rates include approximately 2.5 million TBI-related emergency department visits, 288,000 TBI-related hospitalizations, and 57,000 TBI-related deaths. Each year, the number of new cases of TBI in the Unites States is approximately 2.8 million (CDC, 2015). In the same year, prevalence was 55.5 million individuals, representing an 8.4% increase from 1990 (Global Burden of Disease, 2019). Worldwide, in 2016, there were approximately 27 million new cases of TBI with an age-adjusted incidence rate of 369 per 100,000-representing a 3.6% increase from 1990.

Prevalence refers to the number of individuals who are living with TBI in a given time period. Incidence refers to the number of new cases identified in a specific time period. Caused by high-velocity projectiles, objects of lower velocity such as knives, or bone fragments from a skull fracture that are driven into the brain.

Penetrating TBI-open head injury scalp, skull, and dura mater (outer layer of meninges) are penetrated.

A structural brain imaging study may be normal but usually is abnormal.

Severe TBI-loss of consciousness for more than 24 hours or confused or disoriented state lasting more than 24 hours or memory loss lasting more than 7 days.

A structural brain imaging study may be normal or abnormal.

Moderate TBI-loss of consciousness for more than 30 minutes, but less than 24 hours or confused or disoriented state lasting more than 24 hours or memory loss lasting more than 24 hours but less than 7 days or meets criteria for concussion/mild TBI but with an abnormal CT.

Results of a computed tomography (CT) scan, if obtained, are normal.

Concussion/Mild TBI-loss of consciousness for up to 30 minutes or confused or disoriented state lasting less than 24 hours or memory loss lasting less than 24 hours.

The Department of Defense (DOD) defines the following levels of severity (Defense Health Agency, 2019): Severity of TBI is based on the extent and nature of the injury, duration of loss of consciousness, posttraumatic amnesia (PTA loss of memory for events immediately following injury), and extent of confusion at initial assessment during the acute phase of the injury (APA, 2013 Centers for Disease Control and Prevention, 2015).

Damage can result from a primary injury or a secondary injury (see common classifications of TBI for more details). TBI can cause brain damage that is focal (e.g., gunshot wound) or widespread (e.g., diffuse axonal injury sustained in a motor vehicle accident). Neurological signs, such as brain injury observable on neuroimaging, new onset or worsening of seizure disorder, visual field deficits, and hemiparesis.Confusion associated with deficits in orientation.DSM-5 American Psychiatric Association, 2013), TBI is associated with one or more of the following characteristics:

Consistent with the diagnostic criteria detailed in the Diagnostic and Statistical Manual of Mental Disorders (5th ed. Traumatic brain injury (TBI) is a form of nondegenerative acquired brain injury, resulting from an external physical force to the head (e.g., fall) or other mechanisms of displacement of the brain within the skull (e.g., blast injuries). For information about traumatic brain injury in children (ages birth through 21), see ASHA's Practice Portal page on Pediatric Traumatic Brain Injury. The scope of this page is limited to traumatic brain injury in adults (ages 18 years and older). See the Traumatic Brain Injury (Adults) Evidence Map for summaries of the available research on this topic.
