brain damage

Brain damage occurs when the brain's cells are injured or destroyed, often due to factors like head injury, stroke, infection, or lack of oxygen. This can disrupt normal brain functions such as thinking, memory, movement, or speech. The effects depend on which part of the brain is affected and the severity of the damage. Some damage may be temporary, allowing recovery, while other damage can be permanent. Treatment focuses on managing symptoms and supporting recovery, but some functions may never fully return if the damage is significant.
