HEADACHEDIAGNOSIS.ORG

Less common headache types such as cluster headache may continue for years without proper diagnosis. New therapies are available for each of these conditions... CHAT was developed by Morris Maizels, MD and Patient Tools, Inc to help people with headaches receive an accurate diagnosis. The assessment from CHAT is intended to be reviewed with medical personnel.
