Delayed symptoms are actually pretty common with traumatic brain injuries, and Massachusetts law recognizes this. The brain is complex, and sometimes problems don’t become apparent until someone returns to work or regular activities and realizes they can’t function like they did before. We need to document the timeline carefully. When did the symptoms first appear? What triggered their recognition, and how did that progress? Get medical experts to explain why this delay happened. The key is establishing that connection between the original accident and the later symptoms through medical testimony. Remember, every brain injury is unique, and what might seem like a minor injury on paper can have major life consequences. The insurance companies know this, which is why they fight these cases so hard. Our job is to paint the complete picture of how this injury has changed your life, backed up with solid medical evidence and expert testimony.
