Cognitive defects in migraine have been reported by several authors. These findings however, are controversial. In this study we carried out an investigation on 14 patients with migraine with aura and 16 with migraine without aura according to the International Headache Society criteria. They were submitted to a comprehensive battery of neuropsychological tests. The patients were compared with a control group not significantly different as to age, sex and education. Migraine subjects showed impaired neuropsychological performances only on some cognitive tests. Both groups of patients did worse than the control group on visuo-spatial memory tasks, while only migraineurs without aura showed significantly impaired verbal memory performances. The memory defects, both on visuo-spatial and on verbal cognitive tasks, could depend on an impaired recall mechanism. These memory difficulties seem related to strategically and organizationally defective aspects of learning. 相似文献

The understanding of migraine pathophysiology has evolved from the belief that migraine is a vascular disorder, to evidence
that better defines migraine as a neurogenic disorder associated with secondary changes in brain perfusion. There is evidence
to suggest that the early phase of migraine pain results from neurogenic infiammation affecting cranial blood vessels and
dura. Allodynia, hyperalgesia, and expansion of nociceptive fields occur during most well-established migraine attacks. These
clinical features of migraine are evocative of those traditionally associated with neuropathic pain. A hypothesis that defines
migraine pain as a unique neuropathic pain disorder can imply the potential for neural plasticity and may provide insight
into the mechanisms that underlie the transformation of episodic to chronic forms of migraine. The neuropathic pain model
of migraine pathophysiology not only paves the way for mechanism-based treatment strategies that can improve the acute and
preventive management of migraine attacks, but also opens the door for the discovery of novel therapeutic targets. It also
lends momentum to an understanding of clinically intriguing topics such as opiate-induced hyperalgesia and medication-overuse
headache (rebound headache), opioid resistance in the treatment of chronic headache, and disease modification in defending
against the potential for migraine transformation. 相似文献

Atypical features of hemicrania continua (HC), including both visual aura and side shifting, have been reported previously. However, auras and variable unilaterality have never been reported together in HC. We report two patients with side-shifting HC with aura. These patients' symptoms are unilateral headaches, visual aura, autonomic features, throbbing pain, nausea and photo/phonophobia. One could speculate that the unilaterality and/or the autonomic symptom modules are indomethacin responsive. The patients can also be classified as chronic migraine with aura, with autonomic symptoms, responsive to indomethacin. Neither migraine subtype nor side-shifting HC with aura is included in the current International Headache Society (IHS) classification, so these patients are not classifiable. Side-shifting HC with aura implies the need to revisit the traditional IHS categorization of headaches into unique diagnostic groups. The modular headache theory may be a tool for the understanding of these rare and complex cases. 相似文献

In the present work, we
report that the functional serotonin
transporter gene promoter (5–HTTLPR) polymorphism is
involved in migraine pathogenesis.
The distribution of 5–HTTLPR
genotypes was significantly different
in MA patients (S/S vs. S/L vs.
L/L=32.7 vs. 42.3 vs. 25.0%), MO
patients (18.5 vs. 39.1 vs. 42.4%)
and CON (18.0 vs. 51.3 vs. 30.7%;
chi–square test, p<0.05). In 5–HTTLPR S/S carriers, the odds
ratio for MA risk was 2.60 (95%
confidence interval
[95%CI]=1.75–3.85) compared to
CON, and it was 2.14
(95%CI=1.42–3.21) compared to
MO. These data provide a further
insight on the complex genotypephenotype
relationship involved in
MA pathogenesis, and might eventually
result in new and individualised
prognostic and therapeutic
measures. 相似文献

Spinal cord stroke is uncommon. We report a woman presenting with paraesthesia followed by tetraparesis and respiratory failure who was initially diagnosed as having Guillain-Barré syndrome. Subsequent clinical and imaging features supported the diagnosis of an anterior spinal cord infarction. We describe the main clinical and imaging features of this condition. 相似文献

The prevalence of cervicogenic headache (CEH) is only vaguely known. Furthermore, it is a common belief that in migraine without aura (MwoA), neck symptoms frequently occur and that MwoA and CEH may pathogenetically be intimately related. In the V?g? study, 1838 18-65-year-old citizens (88.6% of that age group) were studied with face-to-face interviews and a thorough neck examination. For CEH, the Cervicogenic Headache International Study Group criteria were used, and for MwoA, the IHS criteria. The extent of cervical involvement was assessed by the 'CF' ('features indicative of cervical abnormality'). CEH prevalence was 4.1%. 'CF' was 2.37 in CEH vs 0.93 in M-A. CEH criteria, e.g. mechanical attack provocation, were present many times more frequently in CEH than in MwoA. Conversely, migraine criteria, e.g. photophobia, were >/= 2.6 times higher in MwoA than in CEH. CEH is unlikely to be a subgroup of MwoA. 相似文献

The demonstration by magnetic resonance imaging (MRI) scanning of thickening and enhancement of the cisternal part of the oculomotor nerve in patients diagnosed as "ophthalmoplegic migraine" prompts reconsideration of this uncommon disorder. The case histories of five patients, three male and two female, varying in age from 6 to 30 years, are presented here. Recurrent painful ophthalmoplegia started in infancy in two cases, childhood in two instances and adult life in one. One child had his first attacks at 3, 5 and 12 months of age, on each occasion 10 days after an injection of triple vaccine. The possibility of this condition being a recurrent demyelinating neuropathy is considered and its possible relationship to migraine explored. 相似文献

Migraine with aura (MA) is associated with changes in cerebral blood flow (CBF), whereas the role of cerebral autoregulation is uncertain. This study aimed to evaluate basal CBF, cerebral blood volume (CBV) and vasomotor reactivity (VMR) in MA patients. Twenty-one controls and 16 MA patients (eight with side predominance) underwent simultaneous examination of flow velocity in the middle cerebral arteries by transcranial Doppler (TCD) and of near-infrared spectroscopy (NIRS) parameters [oxygen haemoglobin saturation: oxygen%, and total haemoglobin content (THC)] at rest and after hypercapnia. Cerebral VMR, THC and oxygen% increases were significantly greater on the predominant compared with the non-predominant migraine side, with both sides of patients without side predominance and with controls. These findings suggest altered autoregulation in MA patients, possibly secondary to impaired cerebrovascular autonomic control. Simultaneous TCD and NIRS investigation could represent a non-invasive approach to evaluate cerebral haemodynamics at the cortical and subcortical level. 相似文献
