What term describes a temporary loss or alteration of brain function without physical damage?

The term that describes a temporary loss or alteration of brain function without physical damage is "cerebral concussion." A concussion is classified as a mild traumatic brain injury that results from a blow to the head or body, causing the brain to move rapidly back and forth within the skull. This jarring motion can lead to biochemical changes in the brain, which may result in various symptoms, including confusion, headache, dizziness, and altered consciousness. Importantly, a concussion does not typically involve structural damage to the brain, unlike more severe injuries such as contusions or hematomas, which would show physical damage on imaging. Understanding the nature of concussions is crucial, as they require appropriate management and care even in the absence of visible injuries on scans.
