Final answer:

Step-by-step explanation:
The statement about traumatic brain injuries (TBIs) that is incorrect is b) They always cause immediate loss of consciousness. While many TBIs can indeed result in the loss of consciousness, it is not a definitive symptom for all cases. Some individuals may remain conscious even after sustaining a brain injury. Falls or accidents are a common cause of TBIs, as stated in option a), and these injuries certainly require medical attention, as suggested in option d). Long-term cognitive effects, such as problems with memory and personality changes, as mentioned in option c), are also possible outcomes. A TBI can vary in severity from a mild concussion that typically heals on its own to more severe injuries that can cause permanent physical or mental disabilities. Therefore, medical evaluation and treatment are crucial in managing TBIs.
