It is an injury to the brain, either by a blow to the head or from being shaken violently. Traumatic brain injuries can affect areas of cognition, language, memory, attention, reasoning, abstract thinking, judgment, problem solving, sensory, perceptual, and motor abilities; psychosocial behavior; physical functions, information processing, and speech.
Traumatic brain injury, also called TBI, can affect different parts of the brain. For example the brain stem, frontal lobe, or temporal lobe may be affected by a traumatic brain injury. The effects of TBI will vary with location. The injury can change the way a person acts, thinks, and moves. Traumatic brain injury can affect an individual physically, cognitively and/or emotionally.
