A neuropsychologist who treated the man suing Gwyneth Paltrow over a 2016 ski collision has testified about his lasting brain injuries. Two of retired optometrist Terry Sanderson's daughters will also likely testify in Park City Thursday about the broken ribs and lasting brain damage that their father Terry Sanderson claims he sustained after he and Paltrow crashed at one of North America’s most upscale ski resorts seven years ago. Paltrow has claimed that Sanderson was actually the culprit for the collision and her attorneys are expected to question the daughters about Sanderson's mentions of her fame.
