Stamford, CT personal injury attorney Stewart Casper talks about the most surprising thing about brain injury cases. He points out that one aspect of brain injury litigation that many people may not realize is the role that defense-retained medical experts can play in evaluating concussion and traumatic brain injury claims. According to him, insurance companies and defense teams often rely on healthcare providers who regularly testify on their behalf, and some may base their opinions on older theories of brain injury rather than the more recent scientific research reflected in current medical literature. He notes that this issue has been particularly revealing to him over the years and remains an area he continues to follow closely as brain injury science continues to evolve.
