You submitted a manuscript to them Tony? Cool!
This is encouraging news. One more avenue being pursued is a great thing! It is a medical school in Sweden apparently, so that is good too!
This is uplifting! I can't help but to become so tired of the "we don't know, how or why" often mentioned in so many research studies. I suppose this recent development/research study is not much different in that way as of yet but the specific dedication to CH is a positive and makes me feel hopeful.
Sounds very good: https://ki.se/en/research/centre-for-cluster-headache
