The brain is an important organ in a living body. Heavy or Major injuries can affect the functioning of the body as the brain is the one that sends signals throughout the body. Brain damage from excessive force falls, or accidents are known as traumatic brain injury. The effects of an injury depend on several factors, including severity, location, and type. Other non-traumatic events and situations can damage the brain, such as stroke, encephalitis, cancer, cerebral hemorrhage, and even abnormally folded proteins such as prions. These affect brain function and can be life-threatening.
