Headache
-
Migraine can be disabling, but it varies greatly in frequency and intensity between individuals. It is not clear which clinical features have the greatest impact on a migraineur's quality of life. ⋯ For a headache referral population, headache intensity appears to be a major determinant of headache-related disability, and it also correlates, to some extent, with the degree of depression and emotional distress present. Headache frequency was not clearly related to disability or psychological factors.
