Major head injuries, also referred to as traumatic brain injuries, are severe compared to minor head injuries. Major head injuries often involve a blow to the head or a penetrating head injury. Symptoms of major head injuries include unconsciousness, seizures, lack of coordination, and severe headaches. Another antonym for minor head injuries could be serious head injuries, which may include skull fractures, intracranial bleeding, and brain tissue damage. Unlike minor head injuries, serious head injuries require immediate medical attention due to the potential risk of permanent brain damage or death. It is essential to seek medical attention for any head injury, particularly those that produce significant symptoms, including confusion, seizures, vomiting, and loss of consciousness, regardless of the severity or antonym.
