I’ve written about hypergraphia before. It’s the medicalized term for compulsive writing (just one form of compulsion-level creativity thought to be linked to temporal lobe oddities, and it’s a way I’ve been described before). It doesn’t have to be any particular kind of writing though. I used to just write lists, or write the words of a book over and over. Many people described as hypergraphic write incredibly detailed journals going over every minute of the day. 

I was telling someone about this years ago. Turns out she was a history major. Her response was “Oh historians love people like that!  That’s how they find out what people’s day to day life was like in the past.”  So that’s one group of people who don’t pathologize hypergraphia.
