Traumatic brain injury commonly results from which of the following?

• A. Open or closed head injury leading to impairment in cognitive, physical, communication, or social areas
• B. Chronic fatigue syndrome
• C. Visual processing delay
• D. Hearing loss

Answer: (A)

Traumatic brain injury happens when an external mechanical force strikes the head, causing damage to brain tissue that can affect thinking, movement, communication, and behavior. The typical forms are open head injuries (where an object penetrates the skull) and closed head injuries (where the head is struck or shaken without penetration). Because the brain can be involved in many functions, TBI often leads to impairments across multiple areas—cognitive (like memory and attention), physical (such as motor skills and balance), communication (speech and language), and social or behavioral functioning. Chronic fatigue syndrome isn’t caused by head injury, and while visual processing delays or hearing loss can occur with various conditions, they don’t capture the broad, external-head-injury mechanism and multi-domain impact that define traumatic brain injury.
