After an incident that may have caused a brain injury, your first priority should be to seek immediate medical attention, even if symptoms seem mild. Contact law enforcement if not already involved, and gather any information you can about the incident, including names and contact details of witnesses. If possible, take photos or videos of the scene and any relevant conditions. Finally, before giving statements to insurance adjusters, consult with a Fresno brain injury attorney who can protect your rights and guide you through the legal process while ensuring your medical needs are documented.
