What are some head injuries that can damage the nervous system?

Head injuries such as concussions, contusions, and traumatic brain injuries (TBIs) can significantly damage the nervous system. A concussion, often resulting from a blow to the head, can disrupt normal brain function and lead to symptoms like confusion and memory loss. Contusions, or bruising of the brain tissue, can cause localized damage and swelling, affecting neurological function. More severe TBIs can result in widespread damage, leading to long-term cognitive, emotional, and physical impairments.
