SYNOPSISA mild electric shock applied to the lower lip was used to elicit reliable evoked potentials from the trigeminal nerve in 20 normal young adults. The wave forms were morphologically similar to those observed with invasive procedures. No substantial differences for either the right or left side of stimulation, recording electrode, or subject sex were obtained for any of the individual potential amplitudes or latencies. The same procedures were applied to 10 patients who had been treated with retrogasserian glycerol injections for trigeminal neuralgia. Trigeminal evoked potentials were elicited in all patients, although the quality of the individual wave forms was more variable than that observed for the normal subjects. Comparison of the treated with the unaffected face side in the patients demonstrated significantly smaller N2‐P2 amplitudes and longer N2 latencies for the affected face side. The results suggest that these procedures produce reliable evoked potential measures of trigeminal nerve function noninvasively which can provide an objective index of treatment efficac

摘要:

SYNOPSISQuestionnaires completed by 327 preclinical medical and dental students showed that 97.9% had experienced headaches, most frequently attributed to insufficient sleep (38.8%), mental stress (38.8%), alcohol (38.5%), excess heat (36.7%), reading (31.5%), excess noise (29.9%) or light (27.7%), and sleeping too long (23.5%). The frequency and duration of these and other headaches are listed. 8% of the headache group had consulted a doctor. Only 2.1% of all students had never experienced a headache.Two hypotheses are examined: (1) can headaches be normal?‐delineated by their disappearing soon after the noxious stimulus has ceased; (2) can pain in the head, as elsewhere in the body, act as a warning and therefore have protective, even survival valu

摘要:

SYNOPSISIn this study, the efficacy of Naproxen sodium (Nxs) in the prophylaxis of Menstrual Migraine (MM) was tested, versus Placebo (PL). Forty women suffering from MM were admitted to a double‐blind treatment protocol with Nxs 550 mg twice each day by mouth or Placebo (PL), for 3 months; in the next 3 months all the women were treated with the active drug in an open study. The headache intensity and duration, as well as the number of days of headache and the analgesic consumption, were significantly reduced with Nxs compared to PL.The efficacy of Nxs, shown also in improving premenstrual pain, and its good tolerability, support the use of this drug in the prophylactic therapy of M

摘要:

SYNOPSIS318 patients satisfying the Ad Hoc Committee's criteria for common or classical migraine were entered into an 8 week single‐blind placebo recording phase to establish, by diary cards, the frequency and severity of their attacks. 176 patients completed this and had records indicating 4–8 episodes in the 8 week period, with sufficient severity to reduce activity and/or work; these patients wore randomized by a predetermined code, into three double‐blinded groups: naproxen sodium 550 mg bid (60 patients), pizotyline 0.5 mg tid (59 patients), or placebo (57 patients). The patients wore followed at monthly intervals for 12 weeks, with 25 dropping out (3 on naproxen sodium, and 2 each on pizotyline and placebo because of “side effects;” the remaining 18 because of noncompliance or reasons unrelated to therapy). Approximately 25% of patients in each of the 3 groups complained of side effects.Statistical analysis showed that both naproxen sodium and pizotyline were better than placebo, and of overall equivalent (i.e. equal) efficacy in the prophylaxis of migraine. In some respects, naproxen sodium was slightly more effective than pizotyline in the first month of

SYNOPSISCriteria for the diagnosis of cervicogenic headache are proposed, which include unilateral head pain, symptoms and signs of neck involvement, non‐clustering episodic moderate pain originating in the neck then spreading to the head, and response to root or nerve blockade; plus rarer and non‐obligatory features such as autonomic disturbances, dizziness, phonophotophobia, monocular visual blurring, and difficulty swallow

摘要:

SYNOPSISA 30‐year‐old woman with a history of common migraine developed a permanent left homonymous hemianopia during a typical headache. CT scan demonstrated a right posterior cerebral infraction and angiography showed irregular narrowing of the ipsilateral posterior cerebral artery, suggestive of vasospasm. In the case no risk factors for atherosclerotic stroke were present except for smoking, and no other causes of stroke could be fo

摘要:

SYNOPSISThis paper describes the development, psychometric properties, and construct and incremental validity of a Headache‐Specific Locus of Control Scale (HSLC). The HSLC is a 33 item scale designed specifically for recurrent headache sufferers. It assesses the individual's perceptions that headache problems and headache relief are determined primarily by: the individual's behavior (Internal factors), Health Care Professionals, or Chance factors. The psychometric properties of the HSLC were satisfactory. Among our findings were that: (1) the belief that headache problems and relief are determined by chance factors was associated with higher levels of depression, physical complaints, reliance on maladaptive pain coping strategies (p<.001), and greater headache‐related disability (p<.01); (2) the belief that headache problems and relief are influenced primarily by the ministrations of health care professionals was associated with higher levels of medication use (p<.01) and preference for medical treatment (p<.001); and (3) the belief that headache problems are determined by the individual's responses and behaviors was associated with a preference for self‐regulation treatment (p<.01). These findings suggest adaptation to headache problems is influenced not only by the frequency and severity of the headache episodes, but by locus of control beliefs. The assessment of locus of control beliefs may provide useful information not typically obtained from standard medical evalua

摘要:

SYNOPSISWe investigated 288 elderly subjects with various degree of dementia, focusing on headaches. Seventy‐three of 288 elderly subjects (25.3%) complained of some headaches. The most common type was the tension‐type headache, from which 43 of the 73 subjects with headaches (58.9%) suffered. The degree of cognitive disturbances, evaluated by Hasegawa's intelligence scale, significantly correlated to the prevalence of headaches, and indicated that patients with dementia appeared to have less headaches. The methodological issues and views on headache research in dementia were assessed, and it is concluded that the field is a difficult one, with potential for er
