Hello zeldaout,
Welcome to the NeuroTalk Support Groups.

It is my understanding that paraneoplastic syndromes are divided into different catagories.

Knowing that catagory would help determine the best forum for you to read and post from the main index page.

Also there is a forum search feature here. You can type in the keyword paraneoplastic and that will bring up past posts across the forums.

take care
