Is a case study on one person too narrow?

I’m a rising junior scheduled to take Research next year, and the other day I started going down the rabbit hole of the case of Clive Wearing. I think his case is super interesting, especially how he’s retained his musical abilities despite his severe amnesia. I think it would be really cool to center my project around him, but I wasn’t able to find a whole lot of information about him from reputable enough sources. I was able to find some stuff about people with similar cases, and I could include them, but I’m not really sure how I’d make it work.

If anyone has any ideas, I’d appreciate it!
