MEDLINE (and it's related PubMED site) [see links on left] have been revised. The new structure makes it easier to find medical literature AND links to other helpful sites--especially for folks who do not have much background in medical terminology. Worthy of exploring.
As with much medical literature, you will often find material on CH cateloged under "migraine" but, if you will push on, you will find the CH specific material.
