Yes. The brain is one of the most intricate and delicate pieces of the human body. Scientists and doctors continue to learn more every day. As such, there is no right or wrong way for a brain to function after an injury. The injuries and symptoms you suffer will be unique and specific to each individual – no two brains are alike. One person may feel symptoms right away, while another may not feel symptoms for days or weeks. Because of the vast differences from person to person, it is very important to contact a personal injury lawyer right away if you have suffered a head injury. A personal injury lawyer can help you obtain medical care, and investigate the circumstances surrounding your injury to determine if a case exists.
