Hyperprolactinemia and headaches.
We investigated the frequency of headaches in women with menstrual abnormalities and hyperprolactinemia. Twenty-seven of 46 (58%) women with hyperprolactinemia indicated that headache episodes occur once or more per week; patients with sellar abnormalities (macroadenoma) or previous cranial or pituitary operation were excluded from this group of hyperprolactinemic patients. The headache episodes occurred significantly more frequently than in the control group (N = 56), where 27% indicated one or more headaches per week (p less than 0.01). In the vast majority of the women with hyperprolactinemia, headaches had preceded the finding of elevated prolactin levels for years and had not developed after the patients had become concerned about the pituitary gland. The clinical impression was that the headaches of these patients typically lack features of prodromal signs and unilaterality and resemble, in general, tension headaches; they may last for hours and often require medication. We could not demonstrate a relationship between prolactin levels and frequency or severity of these headache episodes. The etiology of these headaches is unclear. The therapeutic effect of bromocriptine deserves further investigation. In conclusion, we present data to suggest that headaches are commonly an associated finding in hyperprolactinemic women who have no evidence of significant pituitary enlargement.
