Abstract
BACKGROUND The distinction between a pre-existing primary headache and a secondary headache at the onset of a disorder is important and has not been taken into account in the International Classification of Headache Disorders-3. This study aimed to improve the general diagnostic criteria for secondary headaches using results of our previous studies. MATERIALS AND METHODS We analyzed characteristics of headaches including their changes in intensity, duration, frequency, localization and side, development of new accompanying symptoms, and therapeutic response at the onset of transient ischemic attacks (TIA) (n = 120, mean age 56.1, 55% females) and ischemic stroke (n = 550, mean age 63.1, 56% females) compared to the control group (n = 192, mean age 58.7, 64% females). RESULTS Headache of a new type occurred in 8.4% of ischemic stroke patients and 5% of TIA patients on the day of admission but did not occur at all in the control group. Pre-existing headache with a change of at least one characteristic occurred significantly more often in stroke (5.4%) and TIA (7.5%) than in the control group (1%) (p = 0.01 and p = 0.003 respectively). CONCLUSION The presence of a new type of headache and a pre-existing headache with altered characteristics in close temporal relation to a disorder indicates causality. Based on these data we propose revised general diagnostic criteria for secondary headaches.

Sex steroid hormones and epilepsy: Effects of hormonal replacement therapy on seizure frequency of postmenopausal women with epilepsy-A systematic review. Eur J Neurol 2023; 30:2884-2898. [PMID: 37326003 DOI: 10.1111/ene.15916] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 05/29/2023] [Accepted: 06/07/2023] [Indexed: 06/17/2023]
Abstract
BACKGROUND AND PURPOSE Hormonal replacement therapy (HRT) is used for symptomatic treatment of menopause. Some evidence suggests a proconvulsant effect of estrogen and an anticonvulsant role of progesterone. Thus, the use of exogenous sex steroid hormones might influence the course of epilepsy in peri- and postmenopausal women with epilepsy (WWE). We conducted a systematic review on the impact of HRT on the frequency of seizures of WWE. METHODS PubMed and Scopus were searched for articles published from inception until August 2022. Abstracts from the past 5 years from the European Academy of Neurology and European Epilepsy Congresses were also reviewed. Article reference lists were screened, and relevant articles were retrieved for consultation. Interventional and observational studies on WWE and animal models of estrogen deficiency were included. Critical appraisal was performed using the revised Cochrane risk-of-bias tool for randomized trials and ROBINS-E tool. RESULTS Of 497 articles screened, 13 studies were included, including three human studies. One cross-sectional study showed a decrease in seizure frequency in WWE using combined HRT, a case-control study showed an increase in comparison with controls, and a randomized clinical trial found a dose-dependent increase in seizure frequency in women with focal epilepsy taking combined HRT. Ten studies addressing the impact of HRT in rat models were also included, which showed conflicting results. CONCLUSIONS There is scarce evidence of the impact of HRT in WWE. Further studies should evaluate the harmful potential, and prospective registries are needed for monitoring this population.

Diagnosis of Migrainous Infarction: A Case Report and Analysis of Previously Published Cases. Diagnostics (Basel) 2023; 13:2502. [PMID: 37568864 PMCID: PMC10416890 DOI: 10.3390/diagnostics13152502] [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: 07/03/2023] [Revised: 07/23/2023] [Accepted: 07/25/2023] [Indexed: 08/13/2023] Open
Abstract
Migrainous infarction (MI) is a rare disorder. The precise diagnostic criteria for this diagnosis have been available in the International Classification of Headache Disorders (ICHD) since 1988, but many cases do not fulfil these criteria. This paper describes a good example of MI and analyzes previously published case reports. We report a very special case of MI in an 18-year-old woman who had a recurrent episode of migraine with a similar aura with numbness of the right arm and speech disturbances which had an unusually long duration (>120 min). On admission to the headache centre "Europe-Asia", she complained of slowness of speech and problems with choice of words. An MRI showed acute lacunar infarcts in the left parietal subcortical area. Ischemic infarcts were localized in a relevant area on the left side and the aura symptoms were right-sided. The patient, therefore, fulfilled the ICHD-3 diagnostic criteria for "Migrainous infarction". An analysis of 35 previously published articles with case reports about MI showed that 22 did not meet the diagnostic criteria of the ICHD for migrainous infarction. Using all this, we developed diagnostic recommendations for migrainous infarction which can help to improve the quality of diagnosis when used together with the diagnostic criteria of the ICHD for migrainous infarction.

Abstract
BACKGROUND Direct comparisons of the tolerability and safety of migraine preventive treatments targeting the calcitonin gene-related peptide pathway are lacking. This study aimed to compare the safety and tolerability of anti-calcitonin gene-related peptide monoclonal antibodies and gepants in migraine prevention. METHODS A network meta-analysis of phase 3 randomized controlled trials assessing the safety and tolerability of anti-calcitonin gene-related peptide monoclonal antibodies (erenumab, eptinezumab, fremanezumab, or galcanezumab) and gepants (atogepant, rimegepant) in migraine prevention was performed. Primary outcomes were treatment-emergent adverse events and serious adverse events. Secondary outcomes included any adverse events, adverse events leading to treatment discontinuation and individual adverse events. RESULTS We included 19 randomized controlled trials, comprising 14,584 patients. Atogepant 120 mg (OR 2.22, 95% CI [1.26, 3.91]) and galcanezumab 240 mg (OR 1.63, 95% CI [1.33, 2.00]) showed the largest odds of treatment-emergent adverse events compared to placebo. While eptinezumab 30 mg had greater odds of adverse events leading to treatment discontinuation (OR 2.62, 95% CI [1.03,6.66]). No significant differences in serious adverse events were found between active treatments and placebo. Eptinezumab was associated with the lowest odds of treatment-emergent adverse events and serious adverse events compared to placebo, whereas erenumab was associated with the lowest odds of any adverse events and quarterly fremanezumab with the lowest odds of treatment discontinuation due to adverse events. CONCLUSION Monoclonal antibodies targeting the calcitonin gene-related peptide pathway and gepants are a safe and well tolerated option for migraine prevention.

Clinical characteristics of persistent headaches after the first-ever ischemic stroke (follow-up of 529 patients). CONSILIUM MEDICUM 2023. [DOI: 10.26442/20751753.2022.11.201974] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/07/2023] Open
Abstract
Background. Although persistent headaches are a common post-stroke pain syndrome, the epidemiology and clinical features of persistent headache after first-ever ischemic stroke have not been considered previously. There is no exact data on how often headache attributed to stroke persists for more than 3 months, i.e. meets the criteria for persistent headache after stroke and what are their distinctive clinical features. The tasks of our study were: to analyze the occurrence/incidence of persistent headaches after the first-ever ischemic stroke; to determine clinical characteristics and types of persistent headaches in comparison with headaches at the onset of stroke.
Materials and methods. The study included 550 patients (mean age 63.1 years, 54% men) with first-ever ischemic stroke, of which 529 patients were followed up for at least three months after the stroke. Standardized semi-structured interview forms were used to assess these headaches during professional face-to-face interviews at the onset of stroke and 3 months after the stroke using telephone interview by neurologist.
Results. Among 529 follow up patients 55 (10.4%) had persistent headaches after first-ever ischemic stroke. Among these 55 patients 34 patients had persistent new-type headaches which arose for the first time during the onset of stroke, they included predominated migraine-like headaches (n=20), tension-type-like headaches (n=9) and thunderclap-like headaches (n=5). 21 patients had persistent headaches with altered characteristics: predominated tension-type-like headaches (n=16), and less common migraine-like headaches (n=5). Persistent headaches after stroke had the following characteristics compared to headaches at onset of stroke: severe headache intensity, a gradual decrease of occurrence of accompanying symptoms (photo- and phonophobia; p=0.03), the transition of unilateral headaches in bilateral (p=0.004), the presence of headaches 15 days per month in 30.9% of the patients.
Conclusion. Persistent post-stroke headaches represent a persistent pain syndrome with severe intensity and frequency of attacks, which requires their further study and creation of guidelines for their management.

Abstract
OBJECTIVE To assess the prevalence of various complaints indicating poor sleep quality and its disturbances in men and women with primary headaches. MATERIAL AND METHODS In total 305 patients (mean age 45 years, age range 18-89 years) with primary headache disorders and complaints of poor quality of sleep were included in the study. Women prevailed among these patients (79%). The average age of men (41.6) and women (45.8) had no statistically significant differences (p=0.8). The initial examination and professional face-to-face interview were initially conducted by an experienced neurologist specializing in the treatment of headaches. Within a week after that, before the start of treatment, patients were interviewed by telephone using standardized questionnaires by specially trained students and physicians. RESULTS A frequent occurrence of many complaints of sleep disturbances were found in primary headache disorders, both in men and women, they included daytime sleepiness (75.7%), lack of sleep (69.2%), difficulty in falling asleep (57.4%), sleep disruption (51.5%), early morning awakening (47.5%), snoring (18.7%). We found the predominance of these complaints in people over 50 years old. Women had these complaints more frequently than men, besides we determined sex differences in the prevalence of these complaints. CONCLUSION Complaints about poor sleep quality are quite common in patients with primary headache disorders and have sex and age differences. Identification of the described complaints of poor sleep quality is a simple tool for the initial analysis of sleep disorders in the practice of any specialist. We recommend paying great attention to these complaints for further diagnostics of sleep disorders and their timely treatment.

Abstract
Migraine is one of the leading causes of disability worldwide, especially in women younger than 50 years old. Migraine has three times higher prevalence in women than in men and tends to decrease after the menopausal transition. Migraine has different clinical features in people of different ages. Clinical symptoms and factors associated with migraine can be various in women and men. Women have special types of migraine, such as pure menstrual migraine and menstrually related migraine. Besides, clinical symptoms of migraine can change during pregnancy, postpartum and lactation. Women are significantly more often than men consulting a doctor because of migraine. These features of migraine lead to different treatment and management strategies in females and males of different ages. Migraine therefore is a disorder that demonstrates the necessity of a personalization of healthcare-ensuring the proper treatment for the right patient, at the right time. Considering all the available literature and guidelines, in this chapter several strategies for management of acute and prophylactic treatments of migraine, according to sex and age differences, are discussed. The purpose of this chapter is to provide a useful piece of information improving the treatment and management of migraine.

Abstract
BACKGROUND Neurological disorders pose a profound unmet medical need for which new solutions are urgently needed. The consideration of both biological (sex) and socio-cultural (gender) differences between men and women is necessary to identify more efficacious, safer and tailored treatments. Approaches for putting sex and gender medicine into practice have gathered momentum across Europe, but it is currently unclear to what extent they have been implemented in the field of neurology and neuroscience. METHODS We mapped current activities in research, funding and education aimed at integrating sex and gender consideration in neuroscience and neurology in Europe. We examined and analyzed data gathered from (1) literature searches, (2) policy documents and reports by the European Commission and national funding agencies, (3) web-based searches, (4) "Web of Science", and (5) searches of project databases of funding agencies. An informative / non-systematic search was performed for sections on policies and funding, education, basic research, while a systematic literature and database review was conducted forquantitative analysis of research output and funded projects in terms of sex and gender analysis. RESULTS Our mapping shows that there is a growing interest and attention towards sex and gender consideration in neurological fields, both from funding agencies and researchers. However, most activities, especially for education, are limited to the individual motivation of researchers and are not organically built within curricula and strategic research priorities. DISCUSSION We recommend actions that might help increase the consideration of sex and gender specifically in the field of neuroscience and neurology.

Diagnostic criteria for acute headache attributed to ischemic stroke and for sentinel headache before ischemic stroke. J Headache Pain 2022; 23:11. [PMID: 35057731 PMCID: PMC8903596 DOI: 10.1186/s10194-021-01372-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Accepted: 12/14/2021] [Indexed: 12/15/2022] Open
Abstract
Background Defining the relationship between a headache and stroke is essential. The current diagnostic criteria of the ICHD-3 for acute headache attributed to ischemic stroke are based primarily on the opinion of experts rather than on published clinical evidence based on extensive case-control studies in patients with first-ever stroke. Diagnostic criteria for sentinel headache before ischemic stroke do not exist. The present study aimed to develop explicit diagnostic criteria for headache attributed to ischemic stroke and for sentinel headache. Methods This prospective case-control study included 550 patients (mean age 63.1, 54% males) with first-ever ischemic stroke and 192 control patients (mean age 58.7, 36% males) admitted to the emergency room without any acute neurological deficits or severe disorders. Standardized semi-structured interview forms were used to evaluate past and present headaches during face-to-face interviews by a neurologist on admission to the emergency room in both groups of patients. All headaches were diagnosed according to the ICHD-3. We tabulated the onset of different headaches before a first-ever ischemic stroke and at the time of onset of stroke. We divided them into three groups: a new type of headache, the previous headache with altered characteristics and previous unaltered headaches. The same was done for headaches in control patients within one week before admission to the hospital and at the time of entry. These data were used to create and test diagnostic criteria for acute headache attributed to stroke and sentinel headache. Results Our previous studies showed that headache at onset of ischemic stroke was present in 82 (14.9%) of 550 patients, and 81 (14.7%) patients had sentinel headache within the last week before a stroke. Only 60% of the headaches at stroke onset fulfilled the diagnostic criteria of ICHD-3. Therefore, we proposed alternative criteria with a sensitivity of 100% and specificity of 97%. Besides, we developed diagnostic criteria for sentinel headache for the first time with a specificity of 98% and a sensitivity of 100%. Conclusions We suggest alternative diagnostic criteria for acute headache attributed to ischemic stroke and new diagnostic criteria for sentinel headache with high sensitivity and specificity.

Structured headache services as the solution to the ill-health burden of headache: 1. Rationale and description. J Headache Pain 2021; 22:78.

Abstract
In countries where headache services exist at all, their focus is usually on specialist (tertiary) care. This is clinically and economically inappropriate: most headache disorders can effectively and more efficiently (and at lower cost) be treated in educationally supported primary care. At the same time, compartmentalizing divisions between primary, secondary and tertiary care in many health-care systems create multiple inefficiencies, confronting patients attempting to navigate these levels (the "patient journey") with perplexing obstacles.High demand for headache care, estimated here in a needs-assessment exercise, is the biggest of the challenges to reform. It is also the principal reason why reform is necessary.The structured headache services model presented here by experts from all world regions on behalf of the Global Campaign against Headache is the suggested health-care solution to headache. It develops and refines previous proposals, responding to the challenge of high demand by basing headache services in primary care, with two supporting arguments. First, only primary care can deliver headache services equitably to the large numbers of people needing it. Second, with educational supports, they can do so effectively to most of these people. The model calls for vertical integration between care levels (primary, secondary and tertiary), and protection of the more advanced levels for the minority of patients who need them. At the same time, it is amenable to horizontal integration with other care services. It is adaptable according to the broader national or regional health services in which headache services should be embedded.It is, according to evidence and argument presented, an efficient and cost-effective model, but these are claims to be tested in formal economic analyses.

Abstract
Migraine is a neurovascular disorder that affects over 1 billion people worldwide. Its widespread prevalence, and associated disability, have a range of negative and substantial effects not only on those immediately affected but also on their families, colleagues, employers, and society. To reduce this global burden, concerted efforts are needed to implement and improve migraine care that is supported by informed health-care policies. In this Series paper, we summarise the data on migraine epidemiology, including estimates of its very considerable burden on the global economy. First, we present the challenges that continue to obstruct provision of adequate care worldwide. Second, we outline the advantages of integrated and coordinated systems of care, in which primary and specialist care complement and support each other; the use of comprehensive referral and linkage protocols should enable continuity of care between these systems levels. Finally, we describe challenges in low and middle-income countries, including countries with poor public health education, inadequate access to medication, and insufficient formal education and training of health-care professionals resulting in misdiagnosis, mismanagement, and wastage of resources.

Abstract
No studies have prospectively investigated headache at onset of first-ever ischemic stroke along with a large concurrent control group. Our aims were to answer two important questions: (i) Are headaches at stroke onset causally related to the stroke, and what are their typical clinical characteristics? (ii) What etiology of stroke is associated with these headaches? The study population consisted of 550 patients (mean age = 63.1, 54% males) with first-ever ischemic stroke and 192 control patients (mean age = 58.7, 36% males) admitted to the emergency room without any acute neurological deficits or serious disorders. All data were collected prospectively, using a standardized case-report form during face-to-face interviews by neurologists. Headache at onset of ischemic stroke was present in 82 (14.9%) of 550 patients. More than half (56%) had a new type of headache (mainly migraine-like) simultaneously with stroke onset, and 36% had headache with altered characteristics (mainly tension-type-like headache). Headaches were associated with cardioembolism (p = 0.002, odds ratio [OR] = 2.4, 95% confidence interval [CI] = 1.4-4.1), posterior circulation stroke (p = 0.01, OR = 2.0, 95% CI = 1.2-3.5), infarcts >15 mm (p = 0.03, 95% CI = 1.1-2.7), infarcts of the cerebellum (p = 0.02, OR = 2.3, 95% CI = 1.1-4.8), good neurological status (p = 0.01, OR = 2.5, 95% CI = 1.2-4.9), and low frequency of large-artery atherosclerosis (p = 0.004, OR = 0.4, 95% CI = 0.2-0.8). At stroke onset, headache of a new type and headache with altered characteristics were related to ischemic stroke. They were associated with certain etiologies of stroke.

Abstract
BACKGROUND Making a correct diagnosis of a transient ischemic attack (TIA) is prone to errors because numerous TIA mimics exist and there is a shortage of evidence-based diagnostic criteria for TIAs. In this study, we applied for the first time the recently proposed explicit diagnostic criteria for transient ischemic attacks (EDCT) to a group of patients presenting to the emergency department of a large German tertiary care hospital with a suspected TIA. The aim was to determine the sensitivity and specificity of the EDCT in its clinical application. METHODS A total of 128 patients consecutively presenting to the emergency department of the University Hospital of Lübeck, Germany, under the suspicion of a TIA were prospectively interviewed about their clinical symptoms at the time of presentation. The diagnosis resulting from applying the EDCT was compared to the diagnosis made independently by the senior physicians performing the usual diagnostic work-up ("gold standard"), allowing calculation of sensitivity and specificity of the EDCT. RESULTS EDCT achieved a sensitivity of 96% and a specificity of 88%. When adding the additional criterion F ("the symptoms may not be better explained by another medical or mental disorder"), specificity significantly increased to 98%. CONCLUSIONS The data show that the EDCT in its modified version as proposed by us are a highly useful tool for clinicians. They display a high sensitivity and specificity to accurately diagnose TIAs in patients referred to the emergency department with a suspected TIA.

Abstract
Background There are no previous controlled studies of sentinel headache in ischemic stroke. The purpose of the present study was to evaluate the presence of such headache, its characteristics and possible risk factors as compared to a simultaneous control group. Methods Eligible patients (n = 550) had first-ever acute ischemic stroke with presence of new infarction on magnetic resonance imaging with diffusion-weighted imaging (n = 469) or on computed tomography (n = 81). As a control group we studied in parallel patients (n = 192) who were admitted to the emergency room without acute neurological deficits or serious neurological or somatic disorders. Consecutive patients with stroke and a simultaneous control group were extensively interviewed soon after admission using validated neurologist conducted semi-structured interview forms. Based on our previous study of sentinel headache in transient ischemic attacks we defined sentinel headache as a new type of headache or a previous kind of headache with altered characteristics (severe intensity, increased frequency, absence of effect of drugs) within seven days before stroke. Results Among 550 patients with stroke 94 patients (17.1%) had headache during seven days before stroke and 12 (6.2%) controls (p < 0.001; OR 3.9; 95% CI 1.7–5.8). Totally 81 patients (14.7%) had sentinel headache within the last week before stroke and one control. Attacks of arrythmia during seven days before stroke were significantly associated with sentinel headache (p = 0.04, OR 2.3; 95% CI 1.1–4.8). Conclusions A new type of headache and a previous kind of headache with altered characteristics during one week before stroke are significantly more prevalent than in controls. These headaches represent sentinel headaches. Sudden onset of such headaches should alarm about stroke.

Abstract
Background In the emergency room, distinguishing between a migraine with aura and a transient ischemic attack (TIA) is often not straightforward and mistakes can be harmful to both the patient and to society. To account for this difficulty, the third edition of the International Classification of Headache disorders (ICHD-3) changed the diagnostic criteria of migraine with aura. Methods One hundred twenty-eight patients referred to the emergency room at the University Hospital of Lübeck, Germany with a suspected TIA were prospectively interviewed about their symptoms leading to admission shortly after initial presentation. The diagnosis that resulted from applying the ICHD-3 and ICHD-3 beta diagnostic criteria was compared to the diagnosis made independently by the treating physicians performing the usual diagnostic work-up. Results The new ICHD-3 diagnostic criteria for migraine with aura and migraine with typical aura display an excellent specificity (96 and 98% respectively), and are significantly more specific than the previous ICHD-3 beta classification system when it comes to diagnosing a first single attack (probable migraine with aura and probable migraine with typical aura). Conclusions The ICHD-3 is a highly useful tool for the clinical neurologist in order to distinguish between a migraine with aura and a TIA, already at the first point of patient contact, such as in the emergency department or a TIA clinic.

Abstract
INTRODUCTION ICHD-3 criteria for chronic migraine (CM) include a mixture of migraine and tension-type-like headaches and do not account for patients who have a high frequency of migraine but no other headaches. MATERIALS AND METHODS Patients from the Danish Headache Center and their relatives with ICHD-3 defined CM were compared with patients with high frequency episodic migraine (HFEM). Danish registries were used to compare the socioeconomic impact in these two groups. A Russian student population was used to determine the generalizability of the number of patients fulfilling CM and the proposed diagnostic criteria for CM. RESULTS There was no difference in the demographic profile between the two groups in the Danish cohort. The number of lifelong or annual attacks (p > 0.3), comorbid diseases, or self-reported effect of triptans (p = 1) did not differ. HFEM patients purchased more triptans than CM patients (p = 0.01). CM patients received more early pension (p = 0.00135) but did not differ from HFEM patients with regard to sickness benefit (p = 0.207), cash assistance (p = 0.139), or rehabilitation benefit (p = 1). DISCUSSION Patients with HFEM are comparable to CM patients with regard to chronicity and disability. We therefore suggest classifying CM as ≥ 8 migraine days per month (proposed CM), disregarding the need for ≥ 15 headache days per month. The proposed diagnostic criteria for CM approximately doubled the number of patients with CM in both the Danish and the Russian materials. Extending the definition of CM to include patients with HFEM will ensure that patients with significant disease burden and unmet treatment needs are identified and provided appropriate access to the range of treatment options and resources available to those with CM. CONCLUSION Patients with migraine on eight or more days but not 15 days with headache a month are as disabled as patients with ICHD-3 defined CM. They should be included in revised diagnostic criteria for chronic migraine.

New diagnostic criteria for headache attributed to transient ischemic attacks. J Headache Pain 2019; 20:97. [PMID: 31492115 PMCID: PMC6734282 DOI: 10.1186/s10194-019-1041-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Accepted: 08/12/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The International Classification of Headache Disorders diagnostic criteria for Headache Attributed to Transient Ischemic Attack (TIA) and many other secondary headaches are based primarily on the opinion of experts. The aim of this study was to field test, for the first time, the diagnostic criteria for headache attributed to TIA of the International Classification of Headache Disorders, 3rd edition (ICHD-3) and in case of their weaknesses to propose new diagnostic criteria. METHODS Consecutive patients with Transient Ischemic Attack and a simultaneous control group were extensively interviewed soon after admission. Data were collected on previous headaches, headaches around the time of Transient Ischemic Attack and characteristics of the TIA using validated neurologist conducted semi-structured interview forms. The evidence of relevant infarction were excluded in patients with Transient Ischemic Attack using magnetic resonance imaging with diffusion-weighted imaging (n = 112) or computed tomography (n = 8). RESULTS One hundred twenty patients with Transient Ischemic Attack and 192 controls were included. A new type of headache occurred within 24 h in 16 (13%) of patients with Transient Ischemic Attack and in no controls, a preexisting type of headache with altered characteristics occurred in 9 (7.5%) of patients with Transient Ischemic Attack and no in controls, headache without altered characteristics occurred in 8 (6.6%) of patients with Transient Ischemic Attack and in 9 (4.6%) controls. Only 24% of the headaches in patients with Transient Ischemic Attack (8 of 33 patients) fulfilled the diagnostic criteria of International Classification of Headache Disorders-3 and no control patients. We propose new criteria fulfilled by 94% of the headaches. Specificity remained excellent as only one of 192 controls had a headache fulfilling the proposed criterion C. CONCLUSIONS Existing diagnostic criteria for headache attributed to TIA of the International Classification of Headache Disorders are too insensitive. We suggest new diagnostic criteria with high sensitivity and preserved specificity.

Abstract
Supplemental Digital Content is available in the text. Background and Purpose— The clinical diagnosis of a transient ischemic attack (TIA) can be difficult. Evidence-based criteria hardly exist. We evaluated if the recently proposed Explicit Diagnostic Criteria for TIA (EDCT), an easy to perform clinical tool focusing on type, duration, and mode of onset of clinical features, would facilitate the clinical diagnosis of TIA. Methods— We used data from patients suspected of a TIA by a general practitioner and referred to a TIA service in the region of Utrecht, the Netherlands, who participated in the MIND-TIA (Markers in the Diagnosis of TIA) study. Information about the clinical features was collected with a standardized questionnaire within 72 hours after onset. A panel of 3 experienced neurologists ultimately determined the definite diagnosis based on all available diagnostic information including a 6-month follow-up period. Two researchers scored the EDCT. Sensitivity, specificity, and predictive values of the EDCT were assessed using the panel diagnosis as reference. A secondary analysis was performed with modified subcriteria of the EDCT. Results— Of the 206 patients, 126 (61%) had a TIA (n=104) or minor stroke (n=22), and 80 (39%) an alternative diagnosis. Most common alternative diagnoses were migraine with aura (n=24; 30.0%), stress related or somatoform symptoms (n=16; 20.0%), and syncope (n=9; 11.3%). The original EDCT had a sensitivity of 98.4% (95% CI, 94.4–99.8) and a specificity of 61.3% (49.7–71.9). Negative and positive predictive values were 96.1% (86.0–99.0) and 80.0% (75.2–84.1), respectively. The modified EDCT showed a higher specificity of 73.8% (62.7–83.0) with the same sensitivity and a similar negative predictive value of 96.7%, but a higher positive predictive value of 85.5% (80.3–89.5). Conclusions— The EDCT has excellent sensitivity and negative predictive value and could be a valuable diagnostic tool for the diagnosis of TIA.

Abstract
Background Headache is a common feature in acute cerebrovascular disease but no studies have evaluated the prevalence of specific headache types in patients with transient ischemic attacks (TIA). The purpose of the present study was to analyze all headaches within the last year and the last week before TIA and at the time of TIA. Methods Eligible patients with TIA (n = 120, mean age 56.1, females 55%) had focal brain or retinal ischemia with resolution of symptoms within 24 h without presence of new infarction on MRI with DWI (n = 112) or CT (n = 8). All patients were evaluated within one day of admission by a single neurologist. As a control group we used patients (n = 192, mean age 58.7, females 64%) admitted with diagnoses “lumbago”, “lumbar spine osteochondrosis” or “gastrointestinal ulcer”. Results One-year prevalence of migraine without aura was significantly higher in TIA patients than in controls: 20.8% and 7.8% respectively (p = 0.002, OR 3.1, 95% CI 1.6–6.2). 22 patients (18.3%) had sentinel or warning headache within the last week before TIA. At the time of TIA a new type of headache was observed in 16 patients (13.3%). No controls had a new type of headache. 12 of these 16 patients had migraine-like headache, 8 patients had tension-type-like headache and one patient thunderclap headache. Posterior circulation TIA was associated with headaches within last week before TIA and at the time of TIA much more frequently than anterior circulation TIA. Conclusions The one year prevalence of migraine was significantly higher in TIA patients than in controls and so was the prevalence of headache within the last week before TIA and at the time of TIA. A previous headache that worsens and a new type of headache can be a warning of impending TIA.

Abstract
Background The diagnosis of transient ischemic attacks is fraught with problems. The inter-observer agreement has repeatedly been shown to be low even in a neurological setting, and the specificity of the diagnosis is modest to low, reflected in a poor separation of transient ischemic attacks and mimics, particularly migraine with aura with its varied symptomatology. In other disease areas, explicit diagnostic criteria have improved sensitivity and specificity of diagnoses. We therefore present novel explicit diagnostic criteria for transient ischemic attacks tested for sensitivity and for specificity against migraine with aura. Methods The proposed criteria were developed using the format of the international headache classification. We drew upon the existing literature about clinical characteristics and diagnosis of migraine with aura and transient ischemic attacks. We tested the criteria for sensitivity in a prospectively-collected material of 120 patients with transient ischemic attacks diagnosed before we developed the criteria using extensive semi-structured interview forms in the acute phase after admission. Eligible patients had focal brain or retinal ischemia with resolution of symptoms within 24 hours without presence of new infarction on magnetic resonance imaging with diffusion weighted imaging (n = 112) or computed tomography (n = 8). These criteria were also tested for specificity against a Danish (n = 1390) and a Russian (n = 152) material of patients with migraine with aura diagnosed according to the International Classification of Headache Disorders edition 3 (beta). Results The sensitivity of the proposed criteria was 99% in patients with transient ischemic attacks. The specificity was 95% in the Danish material of patients with migraine with aura and 96% in the Russian material. Conclusions Proposed explicit diagnostic criteria for transient ischemic attacks showed both high specificity and sensitivity. They are likely to improve the emergency room diagnosis of transient ischemic attacks. Further testing in unselected materials referred to transient ischemic attacks clinics was beyond the scope of the present study but is recommended for future study.

Abstract
Introduction The International Classification of Headache Disorders 3rd edition beta (ICHD-3 beta) gave alternative diagnostic criteria for 1.2 migraine with aura (MA) and 1.2.1 migraine with typical aura (MTA) in the appendix. The latter were presumed to better differentiate transient ischemic attacks (TIA) from MA. The aim of the present study was to field test that. Methods Soon after admission, a neurologist interviewed 120 consecutive patients diagnosed with TIA after MRI or CT. Semi-structured interview forms addressed all details of the TIA episode and all information necessary to apply the ICHD-3beta diagnostic criteria for 1.2, 1.2.1, A1.2 and A1.2.1. Results Requiring at least one identical previous attack, the main body and the appendix criteria performed almost equally well. But requiring only one attack, more than a quarter of TIA patients also fulfilled the main body criteria for 1.2. Specificity was as follows for one attack: 1.2: 0.73, A1.2: 0.91, 1.2.1: 0.88 and A1.2.1: 1.0. Sensitivity when tested against ICHD-2 criteria were 100% for the main body criteria (because they were unchanged), 96% for A1.2 and 94% for A1.2.1. Conclusion The appendix criteria performed much better than the main body criteria for 1.2 MA and 1.2.1 MTA when diagnosing one attack (probable MA). We recommend that the appendix criteria should replace the main body criteria in the ICHD-3.

Abstract
Background In our previous study of workers, blood donors and medical students, students stood out with a higher 1-year prevalence of migraine (28%) and tension-type headache (TTH) (74%). General factors associated with headache were common for all groups except low physical activity. The hypothesis of this study was therefore that a number of psychosocial factors relating to the personal sphere would better explain the high prevalence of migraine and TTH in students. Methods The study population consisted of 1042 students (719 females, 323 males, mean age 20.6, range 17–40). Headache diagnoses and associated factors were identified by direct professional semi-structured interview. We also interviewed about the following psychosocial factors: dissatisfaction with study, dissatisfaction with family life, dissatisfaction for personal reasons, bad financial situation, overwork, stress, not enough sleep, insomnia, depressed mood, anxiety, irritability, tendency towards conflicts and not being married. We report psychosocial factors associated with headache according to diagnosis and sex using univariate and multivariate logistic regression analyses. Results Several factors were significantly associated with migraine and TTH in the univariate analysis. In the multivariate analysis, two psychosocial factors were statistically significantly associated with migraine in all students: irritability (OR 2.2, 95% CI 1.4–3.6) and overwork (OR 2.2, 95% CI 1.4–3.5). Insomnia (2.7, 95% CI 1.1–6.9) and depressed mood (OR 2.1, 95% CI 1.1–4.2) were associated with migraine only in females. Two psychosocial factors were associated with TTH: dissatisfaction with study in males (OR 2.0, 95% CI 1.0–3.8) and depressed mood in females (OR 1.8, 95% CI 1.0–3.5). Conclusion Psychosocial factors from the personal sphere showed significant association with migraine and TTH in students. Such factors should therefore be major targets for preventive efforts to reduce the prevalence of primary headache disorders in students.

Abstract
Background Three successive editions of the International Classification of Headache Disorders and multiple guideline papers on headache care have described evidence based diagnosis and treatment of headache disorders. It remains unknown, however, to which extent this has improved the diagnosis and management of headache. That was the aim of our study in which we also analysed differences between three social groups in Russia. Methods We studied 1042 students (719 females, 323 males, mean age 20.6, age range 17–40), 1075 workers (146 females, 929 males, mean age 40.4, age range 21–67) and 1007 blood donors (484 females, 523 males, mean age 34.1, age range 18–64). We conducted a semi-structured, validated, face-to-face professional interview. Data on prevalence and associated factors have previously been published. A section of the interview focused on previous diagnosis and treatment, the topic of this paper. Results Only 496 of 2110 participants (23%) with headache in Russia had consulted because of headache. Students consulted more frequently (35%), workers and blood donors less often (13% and 14%). Only 12% of the patients with ICHD-3beta diagnosis of migraine and 11.7% with ICHD-3beta diagnosis of tension-type headache (TTH) had previously been correctly diagnosed. Triptans were used by only 6% of migraine patients. Only 0.4% of migraine patients and no TTH patients had received prophylactic treatment. Conclusion Despite existing guidelines about diagnosis and treatment, both remain poor in Russia. According to the literature this is only slightly better in Europe and America. Dissemination of existing knowledge should have higher priority in the future.

Abstract
Background The aim of our study was to estimate the one-year prevalence of primary headache disorders in three different social groups using the third edition beta of the International Classification of Headache Disorders (ICHD-3 beta). Material and methods The study population included a total of 3124 participants: 1042 students (719 females, 323 males, mean age 20.6, age range 17–40), 1075 workers (146 females, 929 males, mean age 40.4, age range 21–67) and 1007 blood donors (484 females, 523 males, mean age 34.1, age range 18–64). We used a semi-structured, validated face-to-face interview. Results The age-adjusted one-year prevalence of migraine in females was significantly higher ( p < 0.001) in students (41.9%) than in workers (19.2%) and blood donors (18.7%). Age-adjusted prevalence of migraine among males did not differ among the three groups: 4.5% in students, 4.9% in workers and 4.5% in blood donors. Age-adjusted prevalence of tension-type headache (TTH) among females was almost the same in students and blood donors (68.8% and 66.7%) but female workers had a lower prevalence of TTH (57%). Age-adjusted prevalence of TTH among males did not differ significantly between students and blood donors (55.8% and 58.1%) but male workers had a significantly lower ( p < 0.001) prevalence of TTH (30.7%). The prevalence of chronic headache in students (TTH and/or migraine) was 3% and of probable medication-overuse headache 3%, significantly more than in workers and blood donors. Conclusion Headache prevalence was high and differed markedly among the three social groups. It is important that headache epidemiology also focus on socially defined groups in order to target future preventive efforts.

Abstract
BACKGROUND As major causes of global public ill-health and disability, headache disorders are paradoxically ignored in health policy and in planning, resourcing and implementing health services. This is true worldwide. Russia, where the prevalence of headache disorders and levels of attributed disability are well in excess of the global and European averages, is no exception, while arcane diagnoses and treatment preferences are an aggravating factor. Urgent remedial action, with political support, is called for. METHODS Yekaterinburg, in Sverdlovsk Oblast, is the chosen centre for a demonstrational interventional project in Russia, undertaken within the Global Campaign against Headache. The initiative proposes three actions: 1) raise awareness of need for improvement; 2) design and implement a three-tier model (from primary care to a single highly specialized centre with academic affiliation) for efficient and equitable delivery of headache-related health care; 3) develop a range of educational initiatives aimed at primary-care physicians, non-specialist neurologists, pharmacists and the general public to support the second action. RESULTS AND CONCLUSION We set these proposals in a context of a health-care needs assessment, and as a model for all Russia. We present and discuss early progress of the initiative, justify the investment of resources required for implementation and call for the political support that full implementation requires. The more that the Yekaterinburg headache initiative can achieve, the more likely it is that this support will be forthcoming.

Abstract
OBJECTIVES Our purpose was to identify the incidence and significance of markers of systemic connective tissue abnormalities (CTA) in patients with saccular intracranial aneurysms (SIA). MATERIALS AND METHODS This prospective case-control study included 199 consecutive patients with SIA (103 women and 96 men, mean age - 43.2 years) and 194 control patients - blood donors (108 - men, 86 - women, mean age - 38.4 years). Aneurysms were verified by conventional cerebral angiography. All patients were examined by the first author using a specially designed questionnaire and a standardized physical examination with special emphasis on systemic CTA. RESULTS Twelve markers of systemic CTA were significantly higher in patients with SIA than in controls: visible vessels on face and chest (59.8%), scoliosis (44.7%), varicose veins in legs (39.7%), flatfoot (34.6%), hyperextensibility of the skin (33.6%), spontaneous epistaxis (25.6%), easy bruising (20.6%), abdominal hernia (13.6%), periodontal disease (10.5%), chest deformations (7.5%), abdominal striae (3.5%), joint hypermobility (2.5%). A blinded validation study in a subset of 43 patients showed similar results. Among patients with SIA, 125 of 199 patients (62.8%) had at least three markers of systemic CTA compared with 23 (11.8%) of the controls (P < 0.0001, OR = 12.5, 95% CI 7.45-21.1). The mean number of markers of systemic CTA in patients with SIA was 3.07 and 1.17 in controls. CONCLUSION Patients with SIA have multiple markers of systemic connective tissue abnormalities. Systemic weakness of connective tissue represents a risk factor for development of SIA. Identification of these markers may help in detection of high-risk patients.

Abstract
Background Rupture of a saccular intracranial aneurysm (SIA) causes thunderclap headache but it remains unclear whether headache in general and migraine in particular are more prevalent in patients with unruptured SIA. Methods In a prospective case–control study 199 consecutive patients with SIA (103 females and 96 males, mean age: 43.2 years) received a semistructured face to face interview focusing on past headaches. All were admitted to hospital mostly because of rupture (177) or for unruptured aneurysm (22). In parallel we interviewed 194 blood donors (86 females, 108 males, mean age: 38.4 years). Diagnoses were made according to the International Headache Society criteria. Aneurysms were diagnosed by conventional cerebral angiography. Results During the year before rupture, 124 (62.3%) had one or more types of headache. These headaches included: migraine without aura (MO): 78 (39.2%), migraine with aura (MA): 2 (1%), probable migraine (PM): 4 (2%), tension-type headache (TTH): 39 (19.6%), cluster headache (CH): 2 (1%), posttraumatic headaches (PH): 2 (1%). 1-year prevalence of headaches in controls was 32.5% (63 patients out of 194), they included: TTH: 45 (23.1%), MO: 17(8.8%), PH: 1(0.5%). Only the prevalence of MO was significantly higher in patients with SIA (OR 6.7, 95% CI 3.8-11.9, p < 0.0001). Conclusions Unruptured SIA cause a marked increase in the prevalence of migraine without aura but not in the prevalence of other types of headache.

Abstract
An aim of the study was to compare frequencies of vascular diseases in first-degree relatives (FDR) of patients with intracranial aneurysms (IA) and FDR of controls. Pedigrees have been selected through interviews in 194 patients with IA (96 men and 98 women) and in 193 age- and sex-matched controls. Only FDR with complete information about their disorders have been included in the study: 1011 FDR of patients with IA and 812 controls. The frequency of strokes was 2.5 times and hemorrhages --3.7 times higher in FDR of patients with IA compared to controls. Only 0.9% of FDR of patients with IA had the rupture of intracranial aneurysm. The frequency of headaches was 2.8 times, ischemic heart disease--2.7 times and arterial hypertension --2 times greater in FDR of patients with IA compared to controls. Moreover, sudden death occurred 5.8 times more often in FDR of patients with IA. The data obtained suggest that vascular defects leading to the development of IA may be, in part, genetically determined. Prevention of stroke and cardiovascular disease is necessary for FDR of patients with IA.

Abstract
Background and Purpose—
Genomewide DNA linkage analysis identified a susceptibility locus for intracranial aneurysm (IA) on chromosome 19q13 in the Finnish population, a region including the kallikrein gene cluster. We investigated the association of single nucleotide polymorphisms (SNPs) in the kallikrein gene cluster with IA in the Finnish population.
Methods—
We genotyped 18 haplotype-tagging SNPs spanning a 244 kbp region in the kallikrein gene cluster for 266 Finnish IA cases and 290 Finnish control subjects. In a second phase, we genotyped 2 SNPs (rs1722561 and rs1701946) in an additional set of 102 Finnish IA cases and 102 Finnish control subjects; and in a third phase, we genotyped these 2 SNPs in 156 Russian IA cases and 186 Russian control subjects. Both single-marker and haplotype-based tests of association were performed.
Results—
In phase I, SNPs rs1722561 and rs1701946 were significantly associated with IA in the Finnish population for single locus models (rs1722561:
P
=0.0395; rs1701946:
P
=0.0253). A 2-SNP haplotype block (rs1722561–rs1701946) identified in phase I was also associated with IA in the expanded Finnish (phase II) data set (asymptotic
P
=0.012; empirical
P
=0.019). In the Finnish and Russian combined data set (phase III) with 524 cases and 578 control subjects, the same 2 SNPs (OR: 1.35, 95% CI: 1.14, 1.60;
P
=0.0005 for rs1722561 and OR: 1.32, 95% CI: 1.12, 1.57;
P
=0.0011 for rs1701946) were significantly associated with IA. These SNPs are located in the intronic region of
KLK8
, although linkage disequilibrium could extend from rs268912–rs2250066, a ≈76-kbp region that includes KLK5–KLK10.
Conclusions—
Polymorphisms within the kallikrein gene cluster are associated with IA suggesting that the kallikreins are important candidate genes for IA.

Abstract
An aim of the study was to compare by the analysis of pedigrees the frequency of vascular pathology in first-degree relatives (FDR) of patients with intracranial aneurysms (IA) and controls. Pedigrees were selected by interviewing 194 patients with IA (94 men and 100 women) and 193 age- and sex-matched control patients. Only FDR with complete information about their health status were included: 1011 FDR of patients with IA and 812 FDR of controls. The results of the study revealed that the frequency of strokes was 2.5 times higher in FDR of patients with IA than in those of controls: 6.5% and 2.6%, respectively (RR = 2.52, 95% CI = 1.56-4.09). Hemorrhages occurred 3.7 times more often in FDR of patients with IA than in FDR of controls: 3.4% versus 0.9% (RR = 3.90, 95% CI = 1.74-8.75). Only 0.9% of FDR of patients with IA had the rupture of intracranial aneurysm compared with nobody in FDR of controls. The frequency of headaches was 2.8 times greater in FDR of patients with IA than in those of controls: 19.6% versus 7.1% (RR = 2.74, 95% CI = 2.08-3.62). FDR of patients with IA suffered from arterial hypertension 2 times more often than FDR of controls: 24.9% and 11.6%, respectively (RR = 2.15, 95% CI = 1.73-2.68). Coronary heart disease was 2.7 times more frequent in FDR of patients with IA than in controls: 8.9% and 3.3%, respectively (RR = 2.68, 95% CI = 1.76-4.07). Sudden death occurred in FDR of patients with IA 5.8 times more often than FDR of controls: 11.1% and 1.9%, respectively (RR = 5.68, 95% CI = 1.37-23.39). Thus, vascular pathology occurs relatively often in FDR of patients with IA implying that vascular defects which cause the development of IA may be, at least in part, genetically determined. Prevention of stroke and cardiovascular disease is necessary for FDR of patients with IA.

[The role of angiotensin-converting enzyme and apolipoprotein E in the development of intracranial aneurysms.]. Zh Nevrol Psikhiatr Im S S Korsakova 2007; 107:52-57.

Abstract
The distribution of allele and genotype frequencies of the Alu-insertion polymorphism of the angiotensin-converting enzyme (ACE) gene and missence mutations leading to the substitution of arginine to cysteine in positions 112 and 158 of apolipoprotein E (APOE) has been studied in 166 patients with brain intracranial aneurysms and in 192 controls of Russian origin from Ural region. Brain vascular aneurysms with hypertension were associated with the D*D* ACE genotype in men and with the e2 allele and the e2/e3 APOE genotype in women. The association was also observed between the e2 allele and the e2/e3 APOE genotype and family history of stroke, hemorrhages and aneurysms in patients. Men with the I*D* ACE genotype and the e4 APOE allele were at lower risk.

[The formation of true saccular aneurysms from diverticula of the cerebral arterial walls]. ZHURNAL VOPROSY NEIROKHIRURGII IMENI N. N. BURDENKO 1999:37-9.

Abstract
The authors show that aneurysmic diverticula of cerebral vascular walls cam grow in size and to develop, with time, into true saccular aneurysms. Cases of aneurysmic diverticula transformation into aneurysms illustrate dynamic pattern of aneurysmogenesis and formation of this pathology during life. Feasibility of the growth and rupture of the aneurysm in intracranial hemorrhage dictates necessity of follow-up visualizations of cerebral vessels in such patients (contrast angiography, NMR angiography).

[Heredity in intracranial aneurysms (a study of identical twins)]. ZHURNAL VOPROSY NEIROKHIRURGII IMENI N. N. BURDENKO 1998:33-5.

Abstract
The study of identical twins revealed an important role of hereditary factors in the development of cerebral aneurysms. The "weakness" of connective tissue, caused by some genetic (or polygenic) defects, concurrent with several acquired conditions (essential hypertension, connective tissue disorders) leads to the development and rupture of cerebral aneurysms.
