The definition of headache syndromes in the past have lacked precision, not only because different terms have been used for the same condition, but also because there is no general agreement on the essential characteristics of each. Since even minor variations will produce marked differences in case series purporting to be of the same disorder, it is important to get general agreement and to improve on previous classifications of headache.

Nineteen percent of about 490 patients with classical or common migraine reported that headaches can be precipitated by chocolate, 18% by cheese and 11% by citrus fruit, and a highly significant majority of these patients were sensitive to all three foods. Twenty-nine percent of the patients reported sensitivity to alcohol; again this was significantly associated with sensitivity to the three food stuffs, though a substantial number of patients were sensitive to alcohol but not foods. Thirty-one percent of 331 female patients believed that oral contraceptives precipitated headaches, but this could not be related to any dietary response. Patients with affected relatives were significantly more likely to report sensitivity to alcohol and chocolate; sensitivity to cheese and citrus fruit was less strongly related, and there was no relationship at all for oral contraceptives. These correlations suggest that food induced headaches are mediated by chemical constituents common to these foods.

Platelet monoamine oxidase activity in male migrainous and cluster headache patients was significantly lower than in male controls, confirming our previous study. The activity range showed a normal distribution and low mean values could not be attributed to a subgroup with particularly low activity. When Corash 's platelet preparation method was used, with its high platelet yield, specific enzyme activities of a similar order were obtained. Thus, the low values encountered were not due to abnormal recovery within the platelet population. Two other enzyme activities, phenolsulphotransferase M and succinate dehydrogenase, were also measured in the same platelet samples. Although low succinate dehydrogenase activity was identified in the headache groups, it appeared to represent a separate phenomenon and there was no significant correlation between activity of either enzyme and that of monoamine oxidase. This shows that the low activity of platelet monoamine oxidase in headache is not related to a generalised platelet enzyme deficit. It was also shown that the low monoamine oxidase activity in the headache patients could not be attributed to smoking.

Patients with "mild to moderate" dementia might improve with appropriate drug therapy whereas patients with "severe" dementia are generally considered to have an irreversible condition, providing acute metabolic disorders have been excluded and appropriate investigations have been performed to exclude neurological conditions that might be amenable to neurosurgery. Since it is unlikely that this type of patient will be referred to the hospital outpatient clinics, it is necessary to identify these patients in the community. For this purpose, authors have used the Abbreviated Mental Test. A comparison between two observers (nurse and doctor) has been made. Subsequently, a 6 symptoms check-list, as abbreviated form of the Crichton Royal Rating Scale for geriatric patients, was used in an open pilot study on 260 patients completing a 12 weeks treatment by dihydroergotoxine mesylate (codergocrine mesylate, Hydergine) 4.5 mg once a day. Although this was an open pilot study, it does show that it is possible to identify and treat patients with "mild to moderate" dementia in the community. A single dose formulation in the elderly has obvious advantages. In this study, compliance was excellent and 88% of the patients showed significant improvement using the suggested rating scales.
