Copious, detailed, and diverse evidence make for the strongest TBI case. Keep a detailed record of your symptoms, including their date of onset, how long you’ve experienced them, and how frequently they occur. Seeking medical attention immediately following an accident will dramatically improve both your medical outcome and your chance of receiving a fair settlement. Your doctor should maintain extensive notes on your condition during each visit, and will most likely order diagnostic tests and imaging. An experienced Los Angeles brain injury lawyer can then use this documentation to substantiate your claim.
