When someone gets knocked out, it is typically due to a traumatic brain injury or concussion, which can cause a temporary loss of consciousness. The impact from a blow to the head can cause the brain to move through its protective cerebrospinal fluid, leading to the brain slamming into the skull, which can result in the loss of muscle tone and a complete loss of consciousness. This can cause brain circuits to break, lose their insulation, or get kinked up, shutting off parts of the brain and affecting the brainstem responsible for consciousness. The duration of the loss of consciousness can vary, and if it is very brief, a visit to a primary care doctor may be sufficient, but if the loss of consciousness lasts for more than a minute and symptoms dont fade within a few minutes, it is important to seek medical attention to check for a more severe traumatic brain injury. The long-term effects of being knocked unconscious can include memory problems, mood changes, confusion, and a slower information processing speed. Additionally, fighters who have been knocked out may experience impaired motor skills and may need time to recover and regain their bearings. If a fighter is experiencing unusual symptoms such as nausea or headaches, it is important to seek medical attention, and standardized post-fight medical suspensions may be mandated to ensure proper recovery.
