d Brain injuries can lead to a variety of physical, cognitive, and emotional impairments that can significantly impact a person's functioning and quality of life. The brain is a complex organ responsible for controlling all bodily functions and cognitive processes, so any damage to it can have profound consequences. Additionally, the brain has limited capacity for self-repair, and once brain cells are damaged or killed, they cannot be replaced. This lack of regenerative ability contributes to the long-term effects and potential severity of brain injuries.
