Kay Redfield Jamison has written on this subject- a connection between mental illness and the vague trait of "creativity". Her book Touched With Fire addresses it but she also often lectures on it and has written some other shorter works on the subject. There has been a lot of research lately regarding this idea as well. I think there is some validity to the notion that creativity or an artistic inclination has a connection to mental illness. I just don't think what a lot of people assume- that madness= artistic genius is really how it manifests. It's just not that simple.

No, I didn't read this specific article. I have read a few on the idea and so probably addressed something that was already brought up. [oh well]
