"The IH Registry is run in partnership with Oregon Health & Science University in Portland, Oregon. It is the first and only patient registry of its kind for chronic intracranial hypertension in the world. It represents the largest collection of medical data on chronic IH patients ever compiled and continues to grow. The Registry is international in scope, with patients enrolled from 26 countries; it also welcomes inquiries for collaborative research from researchers outside the US.

It is open to any patient with a confirmed diagnosis of idiopathic or secondary intracranial hypertension, regardless of nationality or country of residence and it is FREE. Any qualified physician researcher or basic researcher from any country in the world is invited to use and receive de-identified medical data once they have confirmed qualifications and receive IRB approval for the research project. The IHRF communicate with Physicians and Researchers globally." The IH Research Foundation
