Few data exist on headache in survivors of acute cerebrovascular disease. During the second year of follow-up of a cohort of intracerebral hemorrhages(ICH),the lifetime history of headache before stroke and 2 years after stroke was characterized through a neurologic interview and a headache questionnaire.Headaches were classified following the International Headache Society classification categories.Disability(Rankin scale)and depression(CERAD depression scale)were also evaluated.Ninety survivors were interviewed.comparing the distribution of pre-and post-ICH headaches,24 subjects(27%)never had headaches,39 subjects(43%)had ongoing headaches,10 subjects(11%)complained of headaches only after ICH,and 17 subjects'(19%)headaches remitted after ICH.There was usually a delay of weeks or months between ICH and the first headache episode.Poststroke headaches were in general less severe and frequent than prestroke headaches.New-onset headaches after ICH were mainly of the tension type and were significantly associated with depression but not with new intracranial lesions.Headaches in remission after ICH were related to acute alcohol consumption and migraines.Chronic post-ICH headaches are usually tension type and occur in association with depression.Remission of headaches after ICH is related to removal of headache precipitants (alcohol)and possibly to structural or functional changes of the trigeminovascular system secondary to intracranial bleeding. |
