Last March, Austin lawyer Patrick Fagerberg realized he’d lost the ability to use the only part of his body that really matters in the legal profession: his brain.

While attending the SXSW music festival in Austin, a large piece of camera equipment fell on Fagerberg’s head during a concert. He was patched up at a local emergency room, he says, but two to three days later he began having trouble forming sentences and organizing his thoughts. The normally affable and quick-witted criminal-defense attorney noticed he was becoming more emotional and foul-tempered. Sometimes he couldn’t even understand his friends’ jokes.
