    Multiple clinical and paraclinical analyses of chronic tension-type headache associated or unassociated with disorder of pericranial muscles (1991)

    Notes: Thirty-two female patients fulfilling the diagnostic criteria of chronic tension-type headache underwent multiple clinical (severity index before and after biofeedback therapy; anxiety score) and paraclinical (pericranial EMG levels and pressure-pain thresholds, temporalis exteroceptive silent period) assessments. Twenty-three patients (72%) had at least one increased EMG level andor at least one decreased pain threshold and qualified for the subgroup “associated with disorder of pericranial muscles” (code 2.2.1). Nine patients (28%) were within the normal range for both investigations and would have been classified in the subgroup “unassociated with such disorder” (code 2.2.2). No significant differences were found between these two groups of patients for headache severity, anxiety, response to biofeedback therapy or duration of temporalis second exteroceptive silent period. The various clinical and paraclinical parameters were not significantly correlated to each other. It is therefore suggested that the subdivision of chronic tension-type headache in two subgroups based on pericranial EMG levels andor pain sensitivity might be artificial. Since both of the latter and temporalis silent periods vary independently, they appear complementary in the study of tension-type headache patients and probably represent peripheral abnormalities, which are induced to varying intensities by a common central nervous system dysfunction.

    Exteroceptive silent period of temporalis muscle in menstrual headaches (1991)
    USA/Oxford, UK : Blackwell Science Ltd
    Cephalalgia 11 (1991), S. 0 
    Details

    Notes: The second exteroceptive silent period (ES2) of temporalis muscle was recorded on days 1 and 15 of the menstrual cycle in 17 women, 9 of whom suffered regularly from tension-type headaches during menstruation. Mean duration of temporalis ES2 was significantly shorter on day I of the cycle than on day 15. This difference was due to a marked menstrual reduction of ES2 in the headache subgroup. A positive correlation was found between ES2 durations and oestradiolprogesterone ratios. We hypothesize that the variations of ES2 during the ovarian cycle result from the modulatory effects of oestrogens on descending aminergic pathways that control excitability of inhibitory brainstem interneurons mediating exteroceptive suppression of jaw-closing motoneurons.

    Contingent negative variation: methods and potential interest in headache (1993)
    USA/Oxford, UK : Blackwell Science Ltd
    Cephalalgia 13 (1993), S. 0 
    Details

    Topics: Medicine
    Notes: Contingent negative variation (CNV) is an event-related slow cerebral potential which has been found abnormal in migraine. Its methodology is described. Contrary to other neurophysiological techniques, CNV needs special equipment and expertise. On average, CNV amplitude is increased and its habituation is lacking in migraine without aura between attacks, but not in migraine with aura. The sensitivity of CNV as a diagnostic tool is low, but its specificity is high. CNV amplitude normalizes after treatment with beta-blockers. The CNV abnormalities in migraine might be due to hyperreactivity of central catecholaminergic pathways.

    Blood magnesium levels in migraine (1991)

    Details
    ISSN: 1468-2982

    Topics: Medicine
    Notes: Serum and erythrocyte magnesium levels were screened between attacks in patients with migraine without aura (n = 38) and with aura (n = 6), and for comparison in a group of patients suffering from chronic tension-type headache (n = 25) as well as a group of neurological, non-headache patients (n = 19). Serum magnesium levels were not significantly different between the four groups of patients. In contrast, magnesium in erythrocytes was on average significantly reduced in patients with migraine without aura compared to the other groups. It is hypothesized that this reduction might be due to an abnormal regulation of intracellular magnesium possibly reflecting at the periphery changes observed in the brain of migraineurs (8).

    Exteroceptive suppression of temporalis muscle activity: methodological and physiological aspects (1993)
    USA/Oxford, UK : Blackwell Science Ltd
    Cephalalgia 13 (1993), S. 0 
    Details

    Notes: In recent years studies of the suppression of EMG activity in temporalis muscle induced by stimulation in the trigeminal territory have opened new perspectives in headache research. The various methods that have been used in different laboratories are reviewed and some of the physiological modulations of temporalis exteroceptive suppression are described. Among different methods of recording, averaging 10 full-wave rectified EMG responses produces results with acceptable variability and discomfort. In order to obtain maximal responses the intensity of the stimulation should reach at least 20 mA. To avoid habituation of the second temporalis exteroceptive suppression period (ES2), the stimulation frequency has to be at O.1 Hz or below. The level of voluntary contraction is not a critical variable as long as it reaches 50% of maximum. Some physiological variations of temporalis suppression are well documented. In females, ES2 is shorter during menstruation than at mid-cycle and correlated with the estradiolprogesterone ratio in plasma. Conditioning temporalis ES2, by a preceding peripheral stimulus markedly reduces its duration, which is partly reversible by naloxone. Various pharmacological agents are able to modify temporalis ES2: its duration is increased by 5-HT1 antagonists, but decreased by 5-HT uptake blockers; contradictory results have been obtained with acetylsalicylic acid. These results suggest that inhibitory brain-stem interneurons mediating temporalis ES2 are inhibited by serotonergic afferents, probably from the raphe magnus nucleus, and that the latter receives an excitatory input from the periaqueductal gray matter and other limbic structures, in part via opioid receptors.
