Urinary output of endogenous monoamine oxidase inhibitor and isatin during acute migraine attacks.

Urinary output of endogenous monoamine oxidase (MAO) inhibitory activity, was significantly raised in serial samples collected across a migraine attack compared with collections during attack-free periods and in healthy controls, which did not differ from each other. There was a highly significant correlation in output between isatin, a major fraction of the MAO inhibitory activity, and output of the MAO inhibitory activity itself. However, although there was a tendency towards increased isatin excretion during migraine attacks, it failed to reach statistical significance.

Acute Disease

Platelet [3H]imipramine binding in migraine and tension headache in relation to depression.

Platelet [3H]imipramine binding was measured in 40 migrainous (7 classical and 33 common) and 17 tension headache patients and in 28 normal controls. A significant reduction in Bmax was found in migraine compared with controls (p less than 0.05) but not in tension headache. In migraine, there was no significant relationship between Bmax and depression or anxiety score on the self-rating Hospital Anxiety and Depression (HAD) Scale, suggesting that the reduction in Bmax is a concomitant of migraine itself rather than a manifestation of associated depression. Preliminary evaluation using the Schedule of Affective Disorders and Schizophrenia-Lifetime Version (SADS-L) tended to confirm this conclusion.

High incidence of endogenous depression in migraine: confirmation by tyramine test.

Forty patients with migraine who were attending a specialist clinic were interviewed with the Schedule for Affective Disorders and Schizophrenia--Lifetime version. Sixteen (40%) had a history of major depression which was of endogenous type in 15, according to Research Diagnostic Criteria. The tyramine test, a previously established trait marker for endogenous depression, showed that the migraine group as a whole had significantly low values compared with 14 normal controls, due almost entirely to low values in the endogenous depressive subgroup; there were no differences between diet-sensitive and non-diet-sensitive migraine patients. Thus depression in patients with migraine seems unlikely to be secondary to migraine per se. A substantial subgroup of patients with migraine may possess an inherent predisposition to endogenous depression.

Neuropsychological assessment of cognitive change in dementia.

The problem of long-term assessment of cognitive change in dementia is defined as that of avoiding floor and ceiling effects in testing. Unlike diagnosis, the establishment of norms is viewed as secondary. This perspective allows the formulation of strategic guidlines in devising test batteries for longitudinal studies of cognitive change in dementia. A number of tests complying with these guidelines are described, tapping a wide range of cognitive abilities such as semantic analysis of verbal and visual material, semantic memory, object recognition, visuoconstruction and serial planning.

Cognition

Cerebral hemisphere function and migraine.

An hypothesis that migraine is the experience of a protective vascular response to cerebral information overload has been explored to a limited extent by examining the association between laterality of the attack and verbal and spatial performances under standard symptom-free conditions. The study was restricted to individuals with unilateral symptoms always presenting on the same side. It emerged that those with classical migraine do not always have prodromata referable to the same side as the pain. Indeed, in the present study, prodromata were almost exclusively referable to the left (dominant) cerebral hemisphere. A subgroup of those with speech disturbances as a feature of the prodromal symptoms was also found to have relatively impaired language abilities on routine testing. It is this finding that lends some support to the hypothesis. The findings also invite the refining proposition that information overload, as defined in the hypothesis, is almost always borne by the dominant (verbal) hemisphere in our species. Such overload might concurrently or sequentially also overtax a suggested limited right hemisphere language capacity, in terms of the hypothesis, accounting for the right-sided pain sometimes presenting in these cases. Otherwise, pain appears to be predominantly left-sided or midline. Perhaps the frequency of this particular syndrome is an indictment of the limitations of language as a basis for communication, as well as reflecting the possibility that most of our stressful transactions and their cerebral processing use a verbal substrate. The results also reveal the need for agreement on rules for classification of laterality in migraine.

Psychiatric morbidity, platelet monoamine oxidase and tribulin output in headache.

A significantly higher proportion of patients with headache showed scores in the psychopathological range of the General Health Questionnaire (GHQ) compared with controls, with ratings particularly high on the anxiety and depression subscales. Across the whole group, there was a significant negative correlation between platelet monoamine oxidase (MAO) activity and GHQ score overall, and with the anxiety and depression subscales. There was a significant positive correlation between platelet MAO activity and urinary output of the endogenous MAO inhibitor, tribulin. Within the migraine group, there was a significant negative correlation between tribulin output and GHQ score. These findings suggest that the biochemical nature of the anxiety associated with migraine may differ from that in other conditions such as generalized anxiety disorder where high platelet MAO activity and high tribulin output have been reported.

Affective Symptoms

Tyramine sulfoconjugation in relation to depression in migraine. A pilot study.

Tyramine sulfoconjugation following an oral tyramine load was determined in 30 patients suffering from migraine and 14 controls not regularly suffering from headache. Reduced tyramine sulfoconjugation was found in those patients with a history of major depressive disorder compared with controls. When the patients with a history of major depression were removed from the analysis, no differences were found between diet-sensitive and non-diet sensitive migraine patients and controls.

Depression

Red wine as a cause of migraine.

Patients with migraine who believed that red wine but not alcohol in general had a headache-provoking effect on them were challenged either with red wine or with a vodka and diluent mixture of equivalent alcohol content, both consumed cold out of dark bottles to disguise colour and flavour. The red wine, which had a negligible tyramine content, provoked a typical migraine attack in 9 of 11 such patients, whereas none of the 8 challenged with vodka had an attack. Neither red wine nor vodka provoked such episodes in other migrainous subjects or controls. These findings show that red wine contains a migraine-provoking agent that is neither alcohol nor tyramine.
