The best time to recover from an infant brain injury is during a child’s infancy, up to the age of three, and the earlier the better. Infant brain injury is a non-progressive brain injury caused by a variety of reasons, and has an impact on a child’s vision, hearing, and intelligence. Brain development in infancy is the most critical period of life and the brain is highly plastic. With timely intervention and treatment, brain function can usually be remodeled to achieve good therapeutic results. The earlier a child with an infant brain injury receives life-saving treatment, the more effective it can be in preventing further damage. In the case of missing the optimal treatment period and not paying attention to the condition, it is easy to make the treatment more difficult. Parents are advised to bring their children to the hospital for clear diagnosis and treatment of brain injury in infants, so as to achieve early intervention and early treatment.
