    Notes: The first descriptions of migraine can be traced back nearly 4,000 years from the ancient civilizations of Mesopotamia (Sumeria and Babylonia) through Egyptian, Greek and Roman epochs. Through Byzantine, Arabic and Medieval times there are only patchy references until the 17th century, when European physicians first gave full case reports.

    Notes: Antiphospholipid antibodies have occasionally been observed in small series of migraine patients, possibly signalling an immunological pathogenesis in a subgroup. We have measured anticardiolipin antibody levels in a series of 94 migraine patients (35 patients having migraine with aura, 59 without aura), during acute attacks and between attacks. Platelet counts were normal and VDRL was negative in all patients. A low positive anticardiolipin antibody level was found in only one patient, which was negative six months later. There appears to be no association between the presence of anticardiolipin antibodies and migraine. Antiphospholipid antibodies are unlikely to have a material pathogenetic role. Statistically, the incidence of significantly raised anticardiolipin antibody levels in this group of patients does not exceed 4% at a 95% probability level.

    Notes: Hepatic cytochrome P450 -dependent oxidation is deficient in 5% to 10% of the Caucasian population. A similar percentage seems to suffer from migraine. The hypothesis was tested that an oxidation deficiency possibly relevant to potential dietary triggers plays a role in the pathogenesis of migraine. In 37 migraine sufferers and 26 controls age- and sex-matched to 26 of these patients, debrisoquine hydroxylation following an oral dose of 10 mg was employed as a marker of oxidation status, determined by calculating the metabolic ratio (MR): urinary debrisoquineurinary 4-hydroxydebrisoquine. MR was similarly distributed in migraineurs and controls. Three subjects in each group were poor metabolizers (MR 〉 30, versus normal range, 0.1–12). MR in patients did not depend on type of migraine (common versus classic), attack frequency, the presence of trigger factors, smoking or a history of adverse reactions or sensitivity to medicines.

    Notes: Analysis of information collected from 468 patients with common or classical migraine does not suggest that those with a longer history are more likely to have headaches fixed to a single side of the head. This finding does not support the notion that successive unilateral headache attacks on one side cause damage that predisposes the patient to further attacks on the same side.

    Notes: In a questionnaire-based study we compared the clinical features of migraine with aura (classical migraine) and migraine without aura (common migraine) in 354 and 397 patients, respectively, attending The Princess Margaret Migraine Clinic. Other than those related to the aura, no significant differences were seen in any clinical features of the attack (e.g. frequency or duration of attacks, time of day at onset, location of headache at onset, severity of headache, or nausea and vomiting). Common migraine attacks were significantly more likely to occur at weekends (p = 0.002). Dietary triggers tended to be more troublesome in classical migraineurs while pregnancy and the menstrual cycle affected both migraine types equally. Classical migraine patients were twice as likely to have a history of hypertension (p 〈 0.05) and showed a slightly but not significantly greater tendency to depression. Family histories of migraine were similar in each migraine type. We conclude that classical and common migraine are fundamentally similar in their clinical characteristics and that the occurrence of focal neurological symptoms during a migraine attack has little influence on the rest of the attack.

    Notes: Platelet 5-hydroxytryptamine (5-HT) uptake was measured in asymptomatic headache patients attending a specialist migraine clinic, and in hospital staff who did not suffer from regular or severe headache. Current levels of anxiety and depression were assessed in all subjects using the Hospital Anxiety and Depression (HAD) scale and their possible influence on the uptake kinetics taken into account during the analysis of results. The Michaelis-Menten constant (Km) was significantly raised in common migraine and tension headache compared with controls (p 〈 0.001 and p 〈 0.01, respectively), but not in classical migraine or cluster headache. The increase remained significant after adjusting for differences in age, sex, presence of anxiety or depression (HAD sub-scale score 3; 8), drug intake during the week before testing, time elapsed since last attack and time of assay (am or pm). No differences were observed between patients and controls in the maximal rate of uptake (Vmax) or platelet count, and previous reports of a reduction in Vmax in patients experiencing attack within 5 days prior to testing could not be confirmed. The cause and significance of an increased Km are not clear, but plasma factors acting as competitive inhibitors for the uptake site or an alteration in the configuration of the uptake site are possible explanations. If confirmed, the shared biochemical abnormality may suggest that common migraine and tension headache have a common pathogenesis.

    Notes: Patients with migraine who believed that chocolate could provoke their attacks were challenged with either chocolate or a closely matching placebo. In a double-blind parallel group study, chocolate ingestion was followed by a typical migraine episode in 5 out of 12 patients, while none of the 8 patients challenged with placebo had an attack (p = 0.051). The median time to the onset of the attack was 22 h. This brief study provides some objective evidence that chocolate is able to provoke a migraine attack in certain patients who believe themselves sensitive to it.

    Notes: Abstract During severe exercise or noradrenaline infusion in healthy male volunteers, the platelet count first rose and then fell. Platelet monoamine oxidase activity per unit protein rose and fell in parallel and the correlation with the platelet count was highly significant (P〈0.001). The increase in observed specific monoamine oxidase activity might be due to the release of a population of platelets with higher specific activity, and the decrease to their selective removal.

    Notes: Abstract This study investigates variations in motor neuron disease (MND) mortality rates between the counties of England and Wales from 1981 to 1989, and their relationship with gamma-ray dose rates, indoor radon gas concentrations and enhanced general life expectancy. A stong correlation was confirmed between age-adjusted rates of MND mortality and life expectancy. Weaker, but statistically significant, associations were observed between indoor radon gas concentrations, terrestrial gamma radiation and marginal variations in MND mortality. Life expectancy and radon gas concentrations were positively associated with MND mortality rates whilst gamma radiation was negatively associated. The negative correlation of gamma radiation with MND mortality may be understood with reference to its negative effects on overall population life expectancy. Radon gas concentrations seemingly account for a small elevation in MND mortality, amounting to at most 4% of total deaths. Further research is required to investigate this association.
