Neurol Int 2023; 15:1238-1252. [PMID: 37873835 PMCID: PMC10594416 DOI: 10.3390/neurolint15040078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 09/28/2023] [Accepted: 10/05/2023] [Indexed: 10/25/2023] Open
Abstract
Autosomal dominant cerebral arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited vascular disease characterized by recurrent strokes, cognitive impairment, psychiatric symptoms, apathy, and migraine. Approximately 40% of patients with CADASIL experience migraine with aura (MA). In addition to MA, CADASIL patients are described in the literature as having migraine without aura (MO) and other types of headaches. Mutations in the NOTCH3 gene cause CADASIL. This study investigated NOTCH3 genetic variants in CADASIL patients and their potential association with headache types. Genetic tests were performed on 30 patients with CADASIL (20 women aged 43.6 ± 11.5 and 10 men aged 39.6 ± 15.8). PCR-HRM and sequencing methods were used in the genetic study. We described three variants as pathogenic/likely pathogenic (p.Tyr189Cys, p.Arg153Cys, p.Cys144Arg) and two benign variants (p.Ala202=, p.Thr101=) in the NOTCH3 gene and also presented the NOTCH3 gene variant (chr19:15192258 G>T), which has not been previously described in the literature. Patients with pathogenic/likely pathogenic variants had similar headache courses. People with benign variants showed a more diverse clinical picture. It seems that different NOTCH3 variants may contribute to the differential presentation of a CADASIL headache, highlighting the diagnostic and prognostic value of headache characteristics in this disease.

Kim BK, Cho S, Kim HY, Chu MK. Validity and reliability of the self-administered Visual Aura Rating Scale questionnaire for migraine with aura diagnosis: A prospective clinic-based study. Headache 2021; 61:863-871. [PMID: 34106459 DOI: 10.1111/head.14133] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 03/22/2021] [Accepted: 04/06/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To assess the validity and reliability of the self-administered Visual Aura Rating Scale (VARS) questionnaire using a hospital-based sample in a cross-sectional setting. BACKGROUND Visual aura is the most common type of aura manifesting in 98%-99% of migraine with aura (MA). The VARS is a diagnostic rating scale used to quantify the cardinal characteristics of MA and has shown high sensitivity and specificity in the diagnosis of visual aura. METHODS We translated the VARS into Korean and constructed a five-item self-administered questionnaire based on the VARS. We consecutively recruited first-visit patients with migraine at the neurology clinics of two university hospitals. The scoring of the self-administered VARS questionnaire was the same as that for the original VARS. We assessed criterion validity and internal consistency reliability. The diagnosis of migraine and aura was assigned by two headache neurologists based on a comprehensive clinical assessment using the International Classification of Headache Disorders, 3rd edition. RESULTS A total of 240 participants with migraine were enrolled. Of these, 55 (22.9%) had MA. All participants with MA had visual aura. Receiver operating characteristic curve analysis revealed that a cutoff score of 3 provided the highest rate of correct identification of patients ([200/240], 83.3%), with a sensitivity of 96.4% (95% confidence interval [CI], 84.5%-99.6%) and specificity of 79.5% (95% CI, 72.9%-85.0%). Cronbach's alpha coefficient was 0.852. CONCLUSION The self-administered VARS questionnaire is a valid and reliable instrument for the screening of visual aura in patients with migraine in neurology outpatient clinics.

Abstract
Background Migraine aura (MA) is a common and disabling neurological condition, characterized by transient visual, and less frequently sensory and dysphasic aura disturbances. MA is associated with an increased risk of cardiovascular disorders and is often clinically difficult to distinguish from other serious neurological disorders such as transient ischemic attacks and epilepsy. Optimal clinical classification of MA symptoms is important for more accurate diagnosis and improved understanding of the pathophysiology of MA through clinical studies. Main body A systematic review of previous prospective and retrospective systematic recordings of visual aura symptoms (VASs) was performed to provide an overview of the different types of visual phenomena occurring during MA and their respective frequencies in patients. We found 11 retrospective studies and three prospective studies systematically describing VASs. The number of different types of VASs reported by patients in the studies ranged from two to 23. The most common were flashes of bright light, “foggy” vision, zigzag lines, scotoma, small bright dots and ‘like looking through heat waves or water’. Conclusions We created a comprehensive list of VAS types reported by migraine patients based on all currently available data from clinical studies, which can be used for testing and validation in future studies. We propose that, based on this work, an official list of VAS types should be developed, preferably within the context of the International Classification of Headache Disorders of the International Headache Society.

Abstract
AIM To examine the characteristics of visual symptoms during attacks of migraine in children and adolescents. METHOD A qualitative analysis of prospectively collected data over 5 years, on characteristics of visual symptoms during migraine attacks. Diagnosis of migraine and aura was based on the International Classification of Headache Disorders 3rd edition beta version. We also provided the opportunity for patients to illustrate their visual aura symptoms to aid in diagnosis. RESULTS Visual symptoms were reported by 387/1079 (36%) of migraineurs. Of these, 172 (16%) patients fulfilled the International Classification of Headache Disorders Criteria A, B, C iv and D, but missed one (n = 75; 43.5%) or two (n = 97; 56.5%) of the remaining items of criteria C as the visual symptoms were of non-gradual spread (n = 35; 20%), appeared in both visual fields (n = 99; 58%), or lasted less than 5 minutes or more than 60 minutes (n = 129; 75%). CONCLUSION The International Classification of Headache Disorders 3rd edition beta version criteria are useful in diagnosis of migraine with visual aura in children and adolescents, but visual symptoms varied considerably in duration, pattern, mobility, location, mode of onset and colours. Providing opportunity for patients to illustrate their symptoms can provide additional diagnostic information. The pathophysiology and the clinical concept of typical MVA is still to an extent an assumption and needs further evaluation. APPROVAL The study was approved by the Health Research Authority - London and the local Research and Innovation Department at Barking Havering and Redbridge National Health Service Trust. Formal parental consent was not considered essential for this type of study.

Abstract
BACKGROUND Migraine is one of the most common chronic neurological disorders. In 1980, C. Miller Fisher described late-life migraine accompaniments as transient neurological episodes in older individuals that mimic transient ischemic attacks. There has not been an update on the underlying nature and etiology of late-life migraine accompanimentsd since the original description. PURPOSE The purpose of this article is to provide a comprehensive and extensive review of the late-life migraine accompaniments including the epidemiology, clinical characteristics, differential diagnosis, and treatment. METHODS Literature searches were performed in MEDLINE®, PubMed, Cochrane Library, and EMBASE databases for publications from 1941 to July 2014. The search terms "Migraine accompaniments," "Late life migraine," "Migraine with aura," "Typical aura without headache," "Migraine equivalents," "Acephalic migraine," "Elderly migraine," and "Transient neurological episodes" were used. CONCLUSION Late-life onset of migraine with aura is not rare in clinical practice and can occur without headache, especially in elderly individuals. Visual symptoms are the most common presentation, followed respectively by sensory, aphasic, and motor symptoms. Gradual evolution, the march of transient neurological deficits over several minutes and serial progression from one symptom to another in succession are typical clinical features for late-life migraine accompaniments. Transient neurological disturbances in migraine aura can mimic other serious conditions and can be easily misdiagnosed. Careful clinical correlation and appropriate investigations are essential to exclude secondary causes. Treatments are limited and still inconsistent.

Abstract
BACKGROUND According to ICHD-II, and as proposed for ICHD-III, non-hemiplegic migraine aura (NHMA) symptoms last between five and 60 minutes whereas hemiplegic migraine aura can be longer. In ICHD-III it is proposed to label aura longer than an hour and less than a week as probable migraine with aura. We tested whether this was appropriate based on the available literature. METHODS We performed a systematic literature search identifying articles pertaining to a typical or prolonged duration of NHMA. We also performed a comprehensive literature search in order to identify all population-based studies or case series in which clinical features of NHMA, including but not restricted to aura duration, were reported, in order to gain a complete coverage of the available scientific data on aura duration. RESULTS We did not find any article exclusively focusing on the prevalence of a prolonged aura or more generally on typical NHMA duration. We found 10 articles that investigated NHMA features, including the aura duration. Five articles recorded the proportion of patients in whom whole NHMA lasted for more than one hour, which was the case in 12%-37% of patients. Six articles reported some information on the duration of single NHMA symptoms: visual aura disturbances lasting for more than one hour occurred in 6%-10% of patients, sensory aura in 14%-27% of patients and aphasic aura in 17%-60% of patients. CONCLUSIONS The data indicate the duration of NHMA may be longer than one hour in a significant proportion of migraineurs. This seems to be especially true for non-visual aura symptoms. The term probable seems inappropriate in ICHD-III so we propose reinstating the category of prolonged aura for patients with symptoms longer than an hour and less than one week.

Abstract
OBJECTIVES To investigate the prevalence, characteristics and clinical correlates of transient visual disturbances (TVDs) in adolescents with headaches. METHODS We surveyed headache-related TVDs in the past three months in two middle schools. All the ninth-grade students filled-in the questionnaires including demographics, a validated headache questionnaire, and visual phenomenon questions embedding the Visual Aura Rating Scale (VARS). TVDs were defined as transient visual phenomena corresponding to a headache attack, but not visual aura, i.e. VARS <four. RESULTS Six hundred and sixty-three adolescents (341 boys and 322 girls; mean age 15.1 ± 0.3 years old) participated in this study. In subjects reporting at least one headache during the past three months (N = 371), 33.4% reported TVDs, which accounted for 18.7% in total participants. TVDs were described mainly as flickering lights or scotoma, movable, monochromatic, occurring over bilateral visual fields, developing and lasting <30 seconds, and experienced during the headache phase. Subjects with migraines reported a higher frequency of TVDs than those with non-migraine headaches (67.1% vs. 31.2%, p < 0.001). TVDs were independently associated with photophobia (OR = 12.6, p < 0.001) and pulsatile headache (OR = 2.1, p = 0.012). CONCLUSIONS The major features of TVDs were distinguishable from visual aura. TVDs were common in adolescents with headaches, especially in migraineurs.

Abstract
Data from the Prolonged Migraine Prevention (PROMPT) with Topiramate trial were evaluated post hoc to determine whether topiramate could prevent migraine auras, and whether its efficacy in preventing migraine headaches was similar in patients with (MA; n = 269) and without (MoA; n = 542) aura. Migraines and auras were recorded during prospective baseline, 6-month open-label (OL) topiramate and 6-month double-blind (DB), placebo-controlled phases. In the last 28 OL days, migraines without aura and migraine auras decreased by 43.1% and 54.1%, respectively, in MA patients. MoA patients experienced a 44.3% reduction in migraines. In the DB phase, increases in migraines with placebo vs. topiramate were similar to the full study, but were generally not statistically significant, probably due to lack of power in the subgroup analysis. Similarly, there were no statistically significant changes in number of auras between groups. Thus, topiramate appears to reduce migraine auras in parallel with headache reductions, which are similar in patients with and without aura.

Abstract
Migraine is a very common disorder characterized by the combination of typical headache with associated autonomic symptoms and/or the presence of aura. Considerable advances have been made in recent years to understand the pathophysiology of migraine, which has led to improved treatment options for the acute migraine attack as well as migraine prophylaxis. Unfortunately, preventive treatment is often insufficient to decrease migraine frequency substantially or is not well tolerated. Topiramate is an antipileptic drug with a complex mode of action which has proven its efficacy and safety in the prophylactic treatment of episodic migraine in a number of randomized controlled clinical trials. Topiramate is also effective in treating patients with chronic migraine. It has little pharmacological interaction with other drugs and is generally well tolerated by patients.

Abstract
Visual aura is the most common feature associated with migraine, though it can occur separately. In both cases it often represents a dramatic event, especially for patients who experience it for the first time. Besides, its subjective characteristics may illuminate on the functional architecture of the visual cortex. Repetitive events of migraine and visual aura have been suggested to affect the visual system in the long run, both on the cortical and precortical level. In effect, objective investigation of visual functions in patients support the idea that a selective damage does occur, so that more attention to visual examination seems to be justified. In this paper, subjective and psychophysical aspects of visual aura are examined, lastly highlighting and discussing the interesting correlations found between this condition and normal-tension glaucoma.

Abstract
Transient visual and neurological episodes are relatively common and can occur for the first time in middle and old age. In many cases these transient events are migraine auras. An aura is a transient, stereotypical, visual or neurological episode usually lasting 4 to 60 minutes in duration. Migraine is usually, but not always, associated with headache and can be accompanied by systemic and autonomic symptoms. Diagnosis is dependent on International Headache Society criteria. The pathophysiology is believed to involve neurovascular mechanisms. There is a hereditary component to migraine. When migraine auras occur in the absence of headache they are termed acephalgic migraines. Late onset migraine accompaniment is an acephalgic migraine that presents in middle-aged and older adults. It is usually benign. Migraines can be mimicked by other more serious conditions. Most patients with a stable migraine pattern and normal neurological evaluation do not require further testing. Some patients with atypical presentation, older age, or suspected secondary causes need further investigation.

Abstract
Migraine affects the cortical physiology and may induce dysfunction both ictally and interictally. Although visual symptoms predominate during aura, other contiguous cortical areas related to less impressive symptoms are also impaired in migraine. Answers from 72.2% migraine with aura and 48.6% of migraine without aura patients on human faces and objects recognition, colour perception, proper names recalling and memory in general showed dysfunctions suggestive of prosopagnosia, dyschromatopsia, ideational apraxia, alien hand syndrome, proper name anomia or aphasia, varying in duration and severity. Symptoms frequently occurred in a successively building-up pattern fitting with the geographical distribution of the various cortical functions. When specifically inquired, migraineurs reveal less evident symptoms that are not usually considered during routine examination. Spreading depression most likely underlies the aura symptoms progression. Interictal involvement indicates that MWA and MWoA are not completely silent outside attacks, and that both subforms of migraine may share common mechanisms.

Abstract
This study was designed to document prospectively and explore scientifically the natural course of untreated migraine attacks in detail. A new, integrated, time-intensity method for self-assessment of the intensity of symptoms was tested on 18 adult International Headache Society migraineurs who volunteered to refrain from treatment during one attack. The area under the curves (AUC) during 72 h of untreated attacks was compared with attacks treated with a triptan. Migraine attacks are heterogeneous both inter- and intra-individually. In untreated attacks, the pain can stabilize and fluctuate around a plateau with a wavelength of hours. In general, the symptoms of each separate migraine attack follow a similar temporal course, with only moderate deviations. In some cases photo- and/or phonophobia (hyperexcitability) were not experienced at all, despite severe pain and nausea. Moreover, there was sometimes no nausea despite severe pain and hyperexcitability. Vomiting does not always correlate to the intensity of nausea and is not always followed by decreased headache intensity. Treatment with a triptan usually only temporarily distorts the basic pattern of attacks. Hyperexcitability can respond before pain to treatment. These genuine findings of the classic symptoms of migraine attacks support the notion of a mutual underlying pathophysiological mechanism.

Abstract
OBJECTIVES Since 1998, migraine with aura (MA) has been diagnosed according to the operational diagnostic criteria of the International Headache Society (ICHD-1). Here we present the data underlying the new criteria for MA in the ICHD-2 classification. METHODS Sensitivity of the new criteria was tested in patients with MA and specificity in patients with reversible non-aura visual disturbances. The diagnoses in both groups of patients were made in a validated semistructured physician-conducted interview. We tested five sets of criteria for sensitivity and specificity comparing with the diagnosis according to the ICHD-1 in 200 patients and the selected set of criteria in 274 additional patients. RESULTS Four sets of criteria had sensitivity/specificity of 46%/100%, 71%/100%, 62%/95%, and 99%/76%. Sensitivity of the selected set of criteria was 84% (95% CI 79% to 90%) and specificity 97% (95% CI 95% to 99%). According to these criteria at least two of the following should be fulfilled: homonymous visual or unilateral sensory symptoms; at least one aura symptom develops gradually over > or =5 minutes and/or different symptoms occur in succession over > or =5 minutes; each symptom lasts > or =5 and < or =60 minutes. In the additional sample sensitivity of the selected criteria was 90% (95% CI 86% to 94%) and specificity 96% (95% CI 91% to 100%). CONCLUSIONS The diagnostic criteria for MA selected for ICHD-2 had high sensitivity and specificity. The ICHD-2 criteria are more operational and probably delineate a more homogeneous sample of patients than the ICHD-1. The ICHD-2 for MA is intended equally for research and clinical practice and can be used at different levels of specialisation.

Abstract
OBJECTIVE To evaluate the prevalence and clinical features of transient visual disturbances (TVDs) during migraine without aura (MO) attacks and to point out any similarities with the disturbances listed among the diagnostic criteria of the International Headache Society (IHS) classification for migraine with aura (MA). METHODS We studied a sample of 191 patients (145 women and 46 men) with MO and no other associated forms of primary headache who had been referred to the University of Parma Headache Centre between December 1, 1999 and December 1, 2000. RESULTS A total of 165 patients reported that they had never experienced TVDs during their MO attacks. In the remaining 26 patients (19 women and 7 men), MO attacks were at times accompanied by TVDs, which were present in over 30% of MO attacks in 65.4% of patients. In about 60% of cases, TVDs lasted less than half a minute. TVDs consisted of phosphenes in most patients, general blurring of vision in about one-fourth, and scintillating scotomas in 15%. In 73% of cases, TVDs occurred during the headache phase, whereas in the remainder they preceded it. Strict application of the IHS diagnostic criteria would have led to a diagnosis of MA in 12 cases, corresponding to 46% of our MO patients with TVDs and to 6.3% of all patients with an established clinical diagnosis of MO. CONCLUSION The results of our study suggest that current IHS diagnostic criteria for MA may lead to an overestimation of MA cases.
