Yes. From my own experience, it seems to be more about increased impulsivity, while pursuing interests to a level that would be uncommon in a "well-rounded" person. I think that impulsivity and creativity are the deeper connection, with all the good and bad that that entails. There's like a sweet spot of impulsivity where you're mostly able to function, but also generate a lot of ideas and connections between disparate topics. So it doesn't really seem that novel that brain damage -> decreased regulation -> increased impulsivity -> creativity. Personality changes like obsession or not caring what others think give the time to work on a problem and harness that increased creativity.
