Here’s an update of my diagram showing the relationships of PSP and CBD to other major neurodegenerative diseases. I’ve added anti-IgLON5 tauopathy-PSP type and created an “Autoimmune” category just for it. This required a little rearranging of other things, and I’ve cleaned up some redundant blue lines, too.

Attention, t-shirt designers: Licensing deals are available.
I’ll have more to say about anti-IgLON5 tauopathy soon.
