Many factors should be considered when an episodic migraine worsens and becomes chronic. Prolactin (PRL) was linked to the origin of pain in patients with microprolactinomas who developed different types of headaches. Our team carried out studies on 27 patients with a background of episodic headaches that became chronic. The patients were evaluated by means of a general examination, a neurological examination and a hormonal profile. Of the 27 patients, 7 of them had an increased level of prolactinaemia. All the patients were women, ranging from 17 to 57 years of age. Four of them had a pure form of migraine without aura, whereas 3 patients had both migraines without aura and tension–type headaches. They suffered from headache for a period ranging from 3 to 32 years and their headache became chronic 4–12 months prior to the visit. Their headache did not change in type, but only in severity and frequency. Two patients had no symptoms referable to high PRL levels; 4 patients had irregular menses or amenorrhoea. One of these patients also suffered galactorrhoea and two of these patients had a microprolactinoma at MRI; one patient was using estroprogestinic drugs, so her menstrual alteration could not be considered. The patients were followed–up for a period of 6–16 months. Six patients responded favourably after being treated with cabergoline, although some had already tried other drugs, which, however, had no effect on their headache. One patient improved after ceasing to take estroprogestinic, in spite of increased levels of PRL. Therefore, on this basis, PRL levels should always be considered when headache worsens. It is an adjunctive worsening factor, which can be easily eliminated.

Migraine is a complex biochemical dysfunction attributed to a disorder of the trigeminal and hypothalamic pathways. Impairment of glucose metabolism has been reported in migraine, but data are scanty and inconsistent.The main aim was to verify whether migraineurs have abnormalities of the glucose and insulin metabolism. We also studied correlations between blood glucose and insulin and between insulin levels and migraine severity.Patients with migraine or headache other than migraine, and healthy volunteers were included. All had general blood tests and a standard oral glucose tolerance test after a 12-hour fast, and glucose and insulin were measured.Over a 6-month period, we recruited 84 migraineurs (73 women, 11 men), 25 patients with nonmigraine headache (20 women, 5 men), and 26 healthy controls (24 women, 2 men). Multivariate analysis confirmed a significant difference between groups for glucose levels (P.0001), but no significant time interaction. The differences were mostly between migraine and healthy controls (P.0001) and to a lesser extent between other headaches and healthy controls (P.05). A significant difference between groups was also found for insulin (P.0001), with a significant time interaction. The difference was confirmed for migraine compared to other headaches (P.0001) and healthy controls (P.0001).Blood glucose levels may be high in headache patients, but do not seem to be specific to migraineurs. Insulin levels were higher in migraineurs, and seemed specific to this group. These findings are in keeping with recent reports on the effects of insulin on brain functions and lend support to the possibility that insulin is involved in the pathogenesis of migraine.
