The article provides an overview of the literature on such medical issue, as cluster headache. The data are given on the prevalence of the disease. The work presents modern data concerning clinical manifestations, diagnosis, most common causes of the cluster headache. Currently, the diagnosis of cephalgia in most developed countries of the world is carried out according to the same standards, among which there is the International classification of headache disorders. Diagnosis of cluster headache is based on the criteria and the elimination of the causes of symptomatic (secondary) headache developed by the International Headache Society. In this work, K.A. Sadokha, A.M. Golovko provides diagnostic criteria, classification, peculiarities of cluster headache course, own clinical observation of the patient with a cluster headache. The article shows the urgency of the problem of cephalgia, as well as the main causes of difficulties in the diagnosis and understanding of headache nature by neurologists.

Відповідно до Міжнародної класифікації головного болю (3-тя редакція (бета-версія), 2013 р.) розглянуто синдроми головних і лицевих болів, що пов’язані з патологією структур шиї. Недостатньо вивченими залишаються патогенетичні механізми саме цервікогенного головного болю, тому цей синдром розглядається як в основній частині класифікації, так і в додатку до класифікації.

Objective To estimate the relative frequencies of hemicrania continua and its clinical features in adult patients who were evaluated for headache in a clinic-based setting. Methods PubMed and Embase were searched for observational, clinic-based studies published between 1 January 2004 and 1 February 2022, that reported on the relative frequencies of hemicrania continua and its clinical features. Two independent investigators (HMA and SA-K) screened titles, abstracts, and full text-articles. A random-effects meta-analysis was conducted to estimate pooled relative frequencies of hemicrania continua and its clinical features across clinic-based studies. Results Eleven clinic-based studies were deemed eligible for inclusion. Of these, eight studies reported on the relative frequency of hemicrania continua among adult patients (n = 9854) who were evaluated for headache in a tertiary care unit. The pooled relative frequency of hemicrania continua was found to be 1.8% (95% CI; 1.0–3.3). Considerable heterogeneity was noted across studies (I2 = 89.8%). The three most common symptoms associated with hemicrania continua were lacrimation (72.3%), conjunctival injection (69.8%), and restlessness/agitation (60.2%). Conclusion The findings of this meta-analysis suggest that there is limited epidemiologic data on the relative frequencies of hemicrania continua and its clinical features. Standardized data acquisition and reporting are needed to estimate prevalence rates more accurately and to better understand epidemiologic patterns. This, in turn, should increase awareness of the impact that hemicrania continua has in clinical practice.

Background: Migraine is one of the most frequent primary headaches in childhood. The role of thrombotic predisposition in its pathogenesis is debated. Our aim was to analyse the cardiovascular risk factors and family history of major thrombotic events in children with migraine. Methods: A retrospective, single-centre study was performed over 12 years. Our headache centre record database was screened for migraine with aura (MA) and migraine without aura (MO) on the basis of the ICHD-II (until 2013) and III criteria. A control group of otherwise healthy children was recruited. Descriptive and multivariate analyses are provided; significance was set at p < 0.05. Results: Migraine was diagnosed in 930 children (24.7% MA); 73.3% were 9–14 years old. Children with MA were older (p < 0.001). A family history of cerebral ischemic events at ≤50 years old was more commonly reported by children with MA than those with MO (p < 0.001) and those in the control group (p = 0.001). Children with MA showed a higher risk of a family history of cerebral ischemic events at ≤50 years old than children with MO (OR: 2.6) and those in the control group (OR: 3.1). When comparing the family history of DVT, we observed a significantly increased risk for MA vs. MO (OR: 2.9). Conclusion: A family history of cerebral ischemic events at ≤50 years old leads to an increased risk of MA. Further studies are needed to explore such an association.

INTRODUCTION The ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE study in Japan (OVERCOME [Japan]) assessed the impact and burden of migraine in Japan. METHODS OVERCOME (Japan) was a cross-sectional, observational, population-based web survey of Japanese people with migraine conducted between July and September 2020. The burden and impact of migraine were assessed using the Migraine Disability Assessment (MIDAS), Migraine-Specific Quality-of-Life Questionnaire (MSQ), Migraine Interictal Burden Scale (MIBS-4), and Work Productivity and Activity Impairment-Migraine scale. Results were stratified by average number of monthly headache days (0-3, 4-7, 8-14, ≥ 15). RESULTS In total, 17,071 Japanese people with migraine completed the survey. Of these, 14,033 (82.2%) met International Classification of Headache Disorders, 3rd edition criteria for migraine and 9667 (56.6%) reported a physician diagnosis of migraine. Overall, 20.7% of respondents experienced moderate-to-severe disability (MIDAS). Moderate-to-severe interictal burden (MIBS-4) was experienced by 41.5% of respondents. MSQ scores in all domains were lowest in respondents with the most frequent headaches (≥ 15 monthly headache days) and highest in those with the lowest frequency headaches (≤ 3 monthly headache days), indicating poorer quality of life in those with more frequent headaches. Work time missed due to migraine (absenteeism) increased with increasing headache frequency, from 3.8 to 6.2%; presenteeism affected 29.8-49.9% of work time. Although migraine burden was greatest in people with the most frequent headaches, those with the lowest headache frequency still experienced substantial disability, interictal burden, and impacts on productivity and quality of life. There was also substantial unmet need for migraine care: 36.5% of respondents had ever hesitated to seek medical care for their headaches, and 89.8% had never used preventive medication. CONCLUSION In Japan, the burden of migraine and barriers to migraine care are substantial. Improving patient awareness and healthcare provider vigilance may help improve patient outcomes.

OBJECTIVE To validate the diagnoses and to investigate epidemiological data from an international, non-clinic-based, and large (n = 1604) survey of participants with cluster headache. BACKGROUND There are several limitations in current epidemiological data in cluster headache including a lack of large non-clinic-based studies. There is also limited information on several aspects of cluster headache, such as pediatric incidence. METHODS The International Cluster Headache Questionnaire was an internet-based survey that included questions on cluster headache demographics, criteria from the International Classification of Headache Disorders (ICHD), and medications. RESULTS A total of 3251 subjects participated in the survey, and 1604 respondents met ICHD criteria for cluster headache. For validation, we interviewed a random sample of 5% (81/1604) of participants and confirmed the diagnosis of cluster headache in 97.5% (79/81). Pediatric onset was found in 27.5% (341/1583) of participants, and only 15.2% (52/341) of participants with pediatric onset were diagnosed before the age of 18. Men were more likely to have episodic cluster headache between ages 10 and 50, but the sex ratio was approximately equal for other ages. An overwhelming majority of respondents had at least one autonomic feature (99.0%, 1588/1604) and had restlessness (96.6%, 1550/1604), but many also had prototypical migrainous features including photophobia or phonophobia (50.1%, 804/1604), pain aggravated by physical activity (31.4%, 503/1604), or nausea and vomiting (27.5%, 441/1604). Interestingly, the first-line medications for acute treatment (oxygen) and preventive treatment (calcium channel blockers) were perceived as significantly less effective in chronic cluster headache (3.2 ± 1.1 and 2.1 ± 1.0 respectively on a 5-point ordinal scale) compared with episodic cluster headache (3.5 ± 1.0 and 2.4 ± 1.1, respectively, p

Background General practitioners (GPs) diagnose and manage a majority of headache patients seeking health care. With the aim to understand the potential for clinical improvement and educational needs, we performed a study to investigate Norwegian GPs knowledge about headache and its clinical management. Methods We invited GPs from a random sample of 130 Norwegian continuous medical education (CME) groups to respond to an anonymous questionnaire survey. Results 367 GPs responded to the survey (73% of invited CME groups, 7.6% of all GPs in Norway). Mean age was 46 (SD 11) years, with an average of 18 (SD 10) years of clinical experience. In general the national treatment recommendations were followed, while the International Classification of Headache Disorders and other international guidelines were rarely used. Overall, 80% (n = 292) of the GPs suggested adequate prophylactic medication for frequent episodic migraine, while 28% (n = 101) suggested adequate prophylactic medication for chronic tension-type headache (CTTH). Half (52%, n = 191)) of the respondents were aware that different types of acute headache medication can lead to medication-overuse headache (MOH), and 59% (n = 217) knew that prophylactic headache medication does not lead to MOH. GPs often used MRI in the diagnostic work-up. GPs reported that lack of good treatment options was a main barrier to more optimized treatment of headache patients. Conclusion The knowledge of management of CTTH and MOH was moderate compared to migraine among Norwegian GPs.

OBJECTIVE To describe the clinical features of new daily persistent headache (NDPH) at an outpatient neurology clinic with a subspecialty interest in headache in Houston, Texas. METHODS A retrospective chart review was performed by a neurologist subspecialty certified in headache medicine of all patients seen from September 1, 2011 through February 28, 2020 (8.5 years) with a provisional diagnosis of NDPH and abstracted charts meeting criteria for primary NDPH. RESULTS A total of 328 patients met the International Classification of Headache Disorders, 3rd edition criteria including 215 (65.5%) female patients. The mean age of onset was 40.3 years (range 12-87 years) with a mean age at first consultation in the study clinic of 42.6 years (range 12-87 years). The median [25th, 75th] duration of NDPH at initial consultation was 0.7 [0.3, 2.0] years, and at last visit, it was 1.9 [0.7, 4.8] years. The headaches were side-locked unilateral in 28/328 (8.5%). 12/328 cases (3.6%) with a thunderclap onset are reported. There was no obvious seasonal or other cyclical variation. The pain was usually moderate to severe and more often severe for the migraine phenotype (MP; 260/328 [79.3%] of cases) than for the tension-type phenotype (TTP). Precipitating factors were the following: stressful life events, 67/328 (20.4%); upper respiratory infection or flu-like illness, 33/328 (10.1%); and extracranial surgery, 5/328 (1.5%). Exacerbating or aggravating factors similar to migraine triggers were more often reported with the MP than with the TTP in this sample. For the MP, vertigo or dizziness was reported by 19/260 (7.3%) and a visual aura by 21/260 (8.1%) with descriptions provided. The prognostic types were the following for all patients: persisting (refractory), 305/328 (93.0%); relapsing-remitting, 9/328 (2.7%); and remitting (self-limited), 14/328 (4.3%). CONCLUSION NDPH is typically of moderate to severe intensity often with migraine features without obvious seasonal or other cyclical variation. Most cases are refractory. 3.6% have a thunderclap onset often with a good response to treatment.

Introduction. A study of medication overuse headache (MOH) can define the risk group for MOH in patients with primary headaches. The aim of the research is to study the socio-demographic, clinical and pharmacotherapeutic characteristics of patients with MOH and chronic tension-type headache (CTTH). Material and methods. We examined 28 patients with MOH in combination with CTTH and 34 patients with CTTH. MOH and CTTH were diagnosed according to the International Classification of Headache Disorders 3rd revision. Anxiety and depressive signs were assessed by the Hospital Anxiety and Depression Scale; abdominal obesity was determined using waist circumference. Quantitative values were presented as the median and the interquartile range. Quantitative samples were analyzed according to Mann-Whitney U-test, qualitative samples - according to Fisher's exact test. Differences at p

Background Coronavirus disease-19 is caused by the severe acute respiratory syndrome coronavirus 2 Headache is a common symptom during and after Coronavirus disease-19. We aimed to study headache character in relation to COVID-19. Methods This was a cross-sectional study. Patients who had Coronavirus disease-19, confirmed by reverse transcription polymerase chain reaction technique and presented to the headache clinic within 3 months after the onset of infections were identified to the study. Study included patients diagnosed as primary headache disorders according to The International Classification of Headache Disorders, 3rd edition. Participants were grouped into categories according to having previous or de novo headache. Descriptive data, paired sample t-test and the chi-squared test (X2) were used for statistical analyses of the data. Results A total of 121 patients were included in this study. Their mean age was 35.29 + 9.54 and most of them were females (83.5%). Prior to Coronavirus disease-19 infections, 78 (64.5%) had migraine and 11(9.1%) experienced a tension-type headache while 32 (26.4) reported de novo headache post Coronavirus disease-19. Patient had significant increase in headache days 11.09 ± 8.45 post Coronavirus disease-19 compared with 8.66 ± 7.49 headache days before Coronavirus disease-19 infection (p p = 0.002) while the patient with tension type headache had statistically significant increase in severity (5.556 ± 1.86 vs 7 ± 2.25, p = 0.033) and frequency (7 ± 6.29 vs 12.72 ± 7.96, p = 0.006) of headache attacks. Bi-frontal and temporal headache are the most reported (40.6% each) headache site among de novo headache group. Patients younger than 40 years had longer duration of the headache attack (18.50 ± 16.44 vs 5.5 ± 9.07, p = 0.045) post COVID-19. Male patients compared to females (8.66 ± 1.15 versus 5.93 ± 2.01 p = 0.04) had more severe headache post Coronavirus disease-19. De novo headache resolved within 1 month in most of patients (65.3%). Conclusion Primary headache get worse after Coronavirus disease-19. De novo primary headache is frequent post Coronavirus disease-19 and resolve within 1 month. Headaches related to Coronavirus disease-19 are severe, present as migraine phenotype. Young male patients with Coronavirus disease-19 tend to have worse headache.

Introduction Subcutaneous trigeminal nerve field stimulation (sTNFS) is a neuromodulatory treatment for neuropathic trigeminal pain with the ability to reduce the intensity and frequency of pain attacks. However, hardware issues including lead migration, skin erosion, infection, so-called pocket pain at the site of the implanted neurostimulator are reported. Implantable wireless neurostimulation technology promises not only an even less invasive sTNFS treatment and thinner and more flexible electrodes better suited for facial implants, but also provides further advantages such as lack of an implantable neurostimulator and 3T magnetic resonance imaging compatibility. Material and methods All patients who had received trial stimulation with a partially implantable sTNFS system were analyzed for ICHD-3 (3rd edition of the International Classification of Headache Disorders) diagnosis, success of trial stimulation, pre- and postoperative pain intensity, frequency of attacks, complications, and side-effects of sTNFS. Results All patients (N = 3) responded to sTNFS (≥50% pain reduction) during the trial period. According to ICHD-3, N = 2 of the patients were classified with trigeminal neuralgia (TN) with concomitant persistent facial pain and N = 1 patient with multiple sclerosis associated TN. The time of the test period was 44 ± 31.24 days (mean ± SD). The average daily duration of stimulation per patient amounted 2.5 ± 2.2 hours (range 1-5). The pain intensity (defined on a visual analog scale) was reduced by 80% ± 17% (mean ± SD). Reduction or cessation in pain medication was observed in all patients. No surgical complications occurred in the long-term follow-up period of 18.84 ± 6 (mean ± SD) months. Conclusion The partially implantable sTNFS device seems to be safe, effective, and reliable. Compared to conventional devices, the equipment is not limited to the length of trial stimulation. Furthermore, the daily stimulation duration was much shorter compared to previous reports.

Introduction The most frequently reported neurological adverse event of ChAdOx1 nCoV-19 (AZD1222) vaccine is headache in 57.5%. Several cases of cerebral venous thrombosis (CVT) have developed after vaccination. Headache is the leading symptom of CVT. For the differential diagnosis of headaches attributed to this vaccine and headaches attributed to CVT, it is of central clinical importance whether and, if so, how the phenotypes and course of these headaches can be differentiated. The study aims to examine in detail the phenotype of headache attributed to this vaccine. Methods Data on the clinical features and corresponding variables were recorded using a standardized online questionnaire in this multicenter observational cohort study. The primary outcomes of this study are the clinical features of headaches after vaccination. Findings A total of 2464 participants reported headaches after vaccination with the ChAdOx1 nCoV-19 (AZD1222) vaccine. On average, headaches occurred 14.5 ± 21.6 h after vaccination and lasted 16.3 ± 30.4 h. A bilateral location was described by 75.8% of participants. This is most often found on the forehead (40.0%) and temples (31.4%); 50.4% reported a pressing and 37.7% a dull pain character. Headache intensity was most often severe (38.7%), moderate (35.2%), or very severe (15.5%). Accompanying symptoms were most commonly fatigue (44.8%), chills (36.1%), exhaustion (34.9%), and fever (30.4%). Conclusion Headaches attributed to COVID-19 vaccination with the ChAdOx1 nCoV-19 (AZD1222) vaccine demonstrate an extensive and characteristic complex of symptoms. The findings have several important clinical implications for the differentiation of post-vaccinal headache and other primary as well as secondary headaches.

Migraine is a complex genetic brain disorder with an intricate pathogenesis and polymorphous clinical presentations, particularly in children. In this Perspective, we describe the different phenotypes of migraine in children, including conditions that have been referred to in the International Classification of Headache Disorders as "syndromes that may be related to migraine''. Evidence is presented for the integration of abdominal migraine, cyclical vomiting syndrome, benign paroxysmal vertigo, benign paroxysmal torticollis and infantile colic into the unified diagnosis of 'childhood migraine syndrome' on the basis of clinical and epidemiological characteristics, and shared inheritance. In our opinion, such integration will guide clinicians from specialities other than neurology to consider migraine in the assessment of children with these disorders, as well as stimulate research into the genetics, pathophysiology and clinical features of all disorders within the syndrome. A diagnosis of childhood migraine syndrome would also enable patients to benefit from inclusion in clinical trials of old and new migraine treatments, thus potentially increasing the number of treatment options available.

Introduction Cluster headaches can occur with considerable clinical variability. The inter- and intra-individual variability could contribute to the fact that the clinical headache phenotype is not captured by too strict diagnostic criteria, and that the diagnosis and the effective therapy are thereby delayed. The aim of the study was to analyze the severity and extent of the clinical symptoms of episodic and chronic cluster headaches with regard to their variability and to compare them with the requirements of the International Classification of Headache Disorders 3rd edition (ICHD-3) diagnostic criteria. Methods The study was carried out as a cross-sectional analysis of 825 patients who had been diagnosed with cluster headaches by their physician. Using an online questionnaire, standardized questions on sociodemographic variables, clinical features of the cluster headache according to ICHD-3, and accompanying clinical symptoms were recorded. Results The majority of patients with cluster headaches have clinical features that are mapped by the diagnostic criteria of ICHD-3. However, due to the variability of the symptoms, there is a significant proportion of clinical phenotypes that are not captured by the ICHD-3 criteria for cluster headaches. In addition, change in the side of the pain between the cluster episodes, pain location, as well as persisting pain between the attacks is not addressed in the ICHD-3 criteria. In the foreground of the comorbidities are psychological consequences in the form of depression, sleep disorders, and anxiety. Conclusions The variability of the phenotype of cluster headaches can preclude some patients from receiving an appropriate diagnosis and effective therapy if the diagnostic criteria applied are too strict. The occurrence of persisting pain between attacks should also be diagnostically evaluated due to its high prevalence and severity as well as psychological strain. When treating patients with cluster headaches, accompanying psychological illnesses should carefully be taken into account.

ObjectiveTo determine the frequency of multiple spinal CSF leaks in a recent group of patients with spontaneous intracranial hypotension (SIH) who were investigated with digital subtraction myelography (DSM).MethodsThis observational study was conducted using data from a prospectively maintained data base of patients who meet the International Classification of Headache Disorders, third edition, criteria for SIH. The patient population consisted of a consecutive group of 745 patients with SIH who underwent DSM between March 2009 and February 2020. Based on the results of DSM, participants were classified according to the type and number of spinal CSF leaks.ResultsAmong 398 patients with SIH and extradural CSF on spinal imaging, multiplicity of CSF leaks was observed in none of 291 patients with type 1a ventral leaks and in 4 (6.2%) of 65 patients with type 1b (postero-) lateral leaks. Among 97 patients with SIH from spinal CSF-venous fistulas (type 3 leaks) who did not have extradural CSF on spinal imaging, 9 patients (9.3%) had multiple fistulas (p < 0.0001 for comparison between groups). Type 3 and type 1a or 1b CSF leaks coexisted in an additional 5 patients.ConclusionsAmong patients with SIH, multiplicity of CSF leaks was observed radiographically in none of the patients with ventral leaks, in 6% of patients with lateral leaks, and in 9% of patients with CSF-venous fistulas. These results suggest that patients with SIH can be reassured that the occurrence of multiple CSF leaks is negligible to uncommon at most, depending on the type of CSF leak.

Introduction It has been shown that a high acid load in the human body can affect inflammatory factors and the nitric oxide pathway. These factors are also thought to play an important role in the initiation of migraine attacks. We have therefore explored the association between dietary acid load and odds of migraine in a case–control study. Methods The migraine group (n = 514, diagnosed according to the International Classification of Headache Disorders 3rd edition [ICHDIII] criteria) was recruited from a tertiary headache clinic. The controls consisted of 582 sex-matched healthy volunteers who were randomly selected from the general population. A validated 168-item semiquantitative food frequency questionnaire was used for dietary intake assessments. Estimation of the dietary acid load was performed using three different measures: potential renal acid load (PRAL) score, net endogenous acid production (NEAP) score, and protein/potassium ratio. Results Multivariable logistic regression analysis showed that, in comparison with the lowest tertile, the highest tertile of dietary acid load measures, including PRAL (odds ratio [OR] 7.208, 95% confidence intervals [CI] 3.33–15.55), and NEAP (OR 4.108, 95% CI 1.924–8.774) scores and the protein/potassium ratio (OR 4.127, 95% CI 1.933–8.814), significantly increased the odds of migraine (P value for trend ≤ 0.001). Conclusion In this study, high dietary acid load was associated with higher odds of migraine. It is therefore possible that restricting dietary acid load could reduce the odds of migraine in susceptible subjects. However, due to the preliminary nature of the current evidence, caution is advised in drawing a definitive conclusion. More well-designed studies are required for a better understanding of this important issue.

Introduction Given the high prevalence of primary headache in the young population, and the rate of pregnancy in this age group, it is unsurprising that pregnant women present a high likelihood of consulting due to headache. Objectives This study seeks to determine the main aetiologies and predictors of headache and the usefulness of the International Classification of Headache Disorders (third edition-beta; ICHD-3 beta) for differentiating primary from non-primary headaches in pregnant women at the emergency department. Patients and methods We performed a cross-sectional study comparing the prevalence of patients meeting the ICHD-3 beta criteria, associated symptoms, history of headache, and demographic features between primary and non-primary headaches. Results Headache was responsible for 142 out of 2952 admissions (4.8%). Headache was primary, non-primary, or unclassified in 66.9%, 27.4%, and 5.6% of cases, respectively. Migraine and headache associated with hypertensive disorders were the most frequent aetiologies for primary and non-primary headaches: 91.6% and 31.4% of cases, respectively. The factors associated with primary headache were fulfilling the ICHD-3 beta criteria (OR: 23.5; 95% CI, 12.5–34.5; p Conclusion In our study, the ICHD-3 beta criteria were useful for differentiating primary from non-primary headaches in pregnant women. History of migraine, history of similar episodes, phosphenes, fever, and high arterial blood pressure were also valuable predictors.

Pain is a common symptom in endodontic conditions, but differential diagnostic procedures are often needed to exclude other pain origins. General dentists and endodontists thus need to be aware of alternative painful orofacial conditions, and be able to identify them. The new International Classification of Orofacial Pain (ICOP, 2020) is the first comprehensive classification that uniquely deals with orofacial pain. The ICOP is a hierarchical classification, modelled on the International Classification of Headache Disorders (ICHD-3) and covers pain in dentoalveolar and anatomically related tissues, muscle pain, temporomandibular joint (TMJ) pain, neuropathic pain affecting cranial nerves, pain resembling primary headaches, and idiopathic pain in the orofacial region. A description of each condition is given, and structured diagnostic criteria for each condition are proposed based on research data when available. This narrative review aims to (i) give an overview and brief explanation of the ICOP system, (ii) describe and give examples of how it can be of use to general dentists and endodontists with special attention to differential diagnosis of tooth pain, and (iii) highlight how endodontic research can contribute to validation and improvement of the classification. A comparison to other classification and diagnostic systems is also included.

Background Migraine auras are transient neurological symptoms, usually lasting for approximately 5 to 30 minutes before the onset of migraine pain. Out of various types of auras, visual aura is the commonest and has variable manifestations, forming approximately 90% of auras. These visual auras may be of particular interest to the ophthalmologist as well as to the neurologist. We planned to conduct this study to look for the prevalence of visual aura in our population and make a descriptive analysis of the same. Materials and Methods It was an observational, questionnaire-based cross-sectional study, enrolling all the consenting patients of migraine. Migraine was classified by International Classification of Headache Disorders (ICHD)-III β version, Third edition of International Classification of Headache Disorders. Patients in whom aura was present, detailed profile of visual aura was made regarding its type, duration, relation with migraine as per its laterality, etc. Observations and Results Out of 1,245 migraine patients, 165 (13.25%) patients reported to have visual aura, 127 females and 38 males. Scintillating scotoma was the commonest type of visual aura, then zigzag lines, blurred vision, and tunnel vision. Majority of patients had aura between 5 and 35 minutes, none had more than 60 minutes. A total of 142 patients out of 165 had unilateral aura, out of which 64 (38.78%) patients had aura ipsilateral to the side of headache, and 78 (47.27%) patients had aura contralateral to the side of headache. Twenty-three (13.93%) patients had bilateral aura. Discussion The frequency of visual aura was found to be 13.25% in our study, which is high compared with previously published Indian data. We did a descriptive analysis of visual aura symptoms. Conclusion Visual aura is the commonest type of aura, more frequent in females. Scintillating scotoma was found to be the commonest type of visual aura, followed by zigzag lines in study. Our study is unique of its type as its shows a descriptive visual analysis in a larger number of patients.

Background While postoperative outcomes of acoustic neuroma (AN) resection commonly consider hearing preservation and facial function, headache is a critical quality of life factor. Postoperative headache is described in the literature; however, there is limited discussion specific to occipital neuralgia (ON) following AN resection. Objective The aim of this study is to investigate the effectiveness of conservative management and surgery. Methods We conducted a retrospective review of 872 AN patients who underwent resection at our institution between 1988 and 2017 and identified 15 patients (1.9%) that met International Classification of Headache Disorders criteria for ON. Results Of the 15 ON patients, surgical approaches included 13 (87%) retrosigmoid (RS), one (7%) translabyrinthine (TL), and one (7%) combined RS + TL. Mean clinical follow-up was 119 months (11–263). Six (40%) patients obtained pain relief through conservative management, while the remaining nine (60%) underwent surgery or ablative procedure. Three (38%) patients received an external neurolysis, four (50%) received a neurectomy, one (13%) had both procedures, and one (13%) received two C2 to 3 radio frequency ablations. Of the nine patients who underwent procedural ON treatment, seven (78%) patients achieved pain relief, one patient (11%) continued to have pain, and one patient (11%) was lost to follow-up. Of the six patients whose pain was controlled with conservative management and nerve blocks, five (83%) found relief by using neuropathic pain medication and one (17%) found relief on nonsteroidal anti-inflammatory drug. Conclusion Our series demonstrates success with conservative management in some, but overall a minority (40%) of patients, reserving decompression only for refractory cases.

Background Headache disorders are rated among the ten most disabling conditions around the world. The primary headache disorders are more common that of secondary headache. The third edition of the International Classification of Headache Disorders (ICHD-III) is considered as a helpful tool for classification and diagnosis of different headache disorders. Methods This is a cross-sectional study that included 500 patients who attended to the headache clinic, between May 2018 and April 2019. Arabic version of headache questionnaire was used to characterize headache, according to ICHD-III. Results Primary headache disorders were found in 89% (most of them is episodic in nature 76.2%), secondary headache disorders in about 10%, and painful cranial neuropathy was present in 0.8%. Primary headache associated with sexual activity was present in 1% of the total number of headache patients, and episodic cluster headache was found in 0.8%. Medication overuse headache (MOH) was the most frequent secondary headache with 2.8% of the total number of headache patients, and when overlaps with chronic migraine or chronic tension type of headache (TTH), the percent was 12.8% and 8.8% respectively. Male to female ratio was 1:3, 3:5, and 1:1 in primary headache, secondary headache, and painful cranial neuropathy respectively. Simple analgesia was the most common abortive therapy (44.8%) while the antidepressants were the most common preventive treatment (17%). Conclusion This study estimates the frequency and characterizes different headache disorders, according to ICHD-III in an outpatient headache clinic at Sohag Governorate, Egypt.

The article is a critical analysis of the diagnostic criteria for medication-overuse headache. This is an important discussion to improve the criteria in the next update, as well as providing a critical view for neurologists when applying the criteria to their clinical practice.

Introduction: Migraine a commonest Neurological disorder that often causes one-sided Headache associated with Nausea, vomiting, Irritability, Photophobia, and Phonophobia.
