Headache diary

Instruct the patient to keep a headache diary to identify potential causes of headaches and responses to therapy. 

These are small documents that form part of the source documents and are usually fQled in by the subject during a study. They allow the subject to record on a daily basis any modest adverse event, for example, headache, that occurs while taking the new treatment or an efficacy parameter, such as a change in their medical condition. Again, care should be taken in the preparation of the diary so that it is user friendly. It should record days and weeks, not dates, use domestic time, not the 24-h clock, and la)unan s terminology. 

Migraine sufferers can take some action against weather-induced headaches. First, keep a diary of their migraines to make cause-and-effect connections. Then, if weather changes seem to play a role in migraines, the next step may be to discuss pretreatment with a doctor to avoid the onset of pain.
