Traumatic Brain Injury
Lesión Cerebral Traumática
Also: Traumatismo Craneoencefálico (regional variant)
What it means
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 (a closed head injury) or when an object penetrates the skull (a penetrating injury). Symptoms can be mild, moderate, or severe. Concussions are a type of mild TBI, and more severe TBI can lead to serious physical and psychological symptoms, coma, and even death. To make a diagnosis, a health care provider will do a neurologic exam, may do imaging tests such as a CT scan or MRI, and may use a tool such as the Glasgow coma scale. The National Institute of Neurological Disorders and Stroke says to seek immediate medical attention if certain symptoms appear after a head injury.

MedlinePlus en español titles its page Lesión cerebral traumática and defines the term there; the page prints it in sentence case, with only the first word capitalized. The noun lesión is feminine, so the adjectives agree with it: la lesión cerebral traumática, and in the plural lesiones cerebrales traumáticas. The same page lists daño cerebral traumático and lesión encefálica traumática as other names, and it keeps the English abbreviation TBI in some of its headings.
The Spanish-language page of the National Institute of Child Health and Human Development gives a different common name, traumatismo cerebral, followed by the words TBI por sus siglas en inglés. Words that MedlinePlus en español prints alongside the term include conmoción cerebral (concussion, a type of mild traumatic brain injury), lesión cerrada de la cabeza (closed head injury), lesión penetrante (penetrating injury) and escala de coma de Glasgow (Glasgow coma scale).

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
