Abstract
OBJECTIVE Other primary headache disorders (OPHD) are under-investigated compared to frequent primary headache types like migraine, tension-type headache, and trigeminal autonomic cephalalgias. Knowledge of the distribution and characteristics of OPHD subtypes is crucial for their recognition. We aimed to determine the prevalence at the hospital and headache clinics and clinical characteristics of OPHDs in patients from 13 countries. METHODS We analyzed a large dataset from the cross-sectional study Head-MENA-A (Middle East, North Africa, Asia). Consecutive patients over 10 years of age presenting with headaches were included from outpatient, inpatient, and emergency settings. A structured questionnaire addressing demographics, headache characteristics, accompanying symptoms, and triggers was administered. Headache subtypes were diagnosed according to the ICHD-3 criteria. RESULTS Among patients complaining of headaches (n = 3722), 106 (2.9%) were diagnosed with OPHD. Fifty-two patients (1.4% of all headache patients) had only OPHD, while 54 (1.5%) had both OPHD and a co-existing primary headache (mostly migraine). All OPHDs were more common in females. The most frequent subtypes were new daily persistent headache and primary stabbing headache (0.2% each among all admitted patients). Photophobia and phonophobia were the most frequent accompanying symptoms, while physical activity (28.8%), stress (15.4%), and the Valsalva maneuver (15.4%) were the most common triggering factors. The majority of triggering factors were more pronounced in patients with both migraine and OPHD. CONCLUSIONS Other primary headaches are rare and heterogeneous. Their high co-existence with migraine suggests shared predisposing factors, hinting at a "headache continuum" concept for primary headaches.

Abstract
INTRODUCTION Uniform case definitions are required to ensure harmonised reporting of neurological syndromes associated with SARS-CoV-2. Moreover, it is unclear how clinicians perceive the relative importance of SARS-CoV-2 in neurological syndromes, which risks under- or over-reporting. METHODS We invited clinicians through global networks, including the World Federation of Neurology, to assess ten anonymised vignettes of SARS-CoV-2 neurological syndromes. Using standardised case definitions, clinicians assigned a diagnosis and ranked association with SARS-CoV-2. We compared diagnostic accuracy and assigned association ranks between different settings and specialties and calculated inter-rater agreement for case definitions as "poor" (κ ≤ 0.4), "moderate" or "good" (κ > 0.6). RESULTS 1265 diagnoses were assigned by 146 participants from 45 countries on six continents. The highest correct proportion were cerebral venous sinus thrombosis (CVST, 95.8%), Guillain-Barré syndrome (GBS, 92.4%) and headache (91.6%) and the lowest encephalitis (72.8%), psychosis (53.8%) and encephalopathy (43.2%). Diagnostic accuracy was similar between neurologists and non-neurologists (median score 8 vs. 7/10, p = 0.1). Good inter-rater agreement was observed for five diagnoses: cranial neuropathy, headache, myelitis, CVST, and GBS and poor agreement for encephalopathy. In 13% of vignettes, clinicians incorrectly assigned lowest association ranks, regardless of setting and specialty. CONCLUSION The case definitions can help with reporting of neurological complications of SARS-CoV-2, also in settings with few neurologists. However, encephalopathy, encephalitis, and psychosis were often misdiagnosed, and clinicians underestimated the association with SARS-CoV-2. Future work should refine the case definitions and provide training if global reporting of neurological syndromes associated with SARS-CoV-2 is to be robust.

Abstract
BACKGROUND Headaches are frequent neurological disorders that are yet to be unveiled and treated comprehensively worldwide. Bearing in mind that the distribution of headache subtypes in neurology clinics (NC) is essential for planning appropriate diagnostic and therapeutic approaches, the primary goals of this multi-centric study are to carry out inter-regional comparisons by using current diagnostic criteria with evaluations of neurologists to delineate headache burden. METHODS A cross-sectional study between April 1 and May 16, 2022 was conducted with the participation of 13 countries from the Middle East, Asia, and Africa. Patients were included in the study on a specific day each week during five consecutive weeks. All volunteers over the age of 18 and whose primary cause for admission was headache were examined. The patients admitted to NC or referred from emergency services/other services were evaluated by neurologists by means of the International Classification of Headache Disorders (ICHD-3) criteria. RESULTS Among the 13,794 patients encountered in NC, headache was the primary complaint in 30.04%. The headache patients' mean age was 42.85 ± 14.89 (18-95 years), and 74.3% were female. According to the ICHD-3 criteria, 86.7% of the main group had primary headache disorders, 33.5% had secondary headaches, 4% had painful cranial neuropathies along with other facial and headaches, and 5.2% had headaches included in the appendix part showing some overlapping conditions. While the most common primary headache was migraine without aura (36.8%), the most common secondary headache was medication-overuse headache (MOH) (9.8%). Headaches attributed to COVID-19, its secondary complications, or vaccines continue to occur at rates of 1.2%-3.5% in current neurology practice. Pain severity was significantly lower in Ivory Coast and Sudan than in Türkiye, Turkish Republic of Northern Cyprus, Iran, Egypt, Senegal, Tatarstan, and Azerbaijan (p < 0.001). CONCLUSIONS The study showed that migraine is still the most common motive for admissions to NC in different regions. Furthermore, MOH, an avoidable disorder, is the most common secondary headache type and appears to be a significant problem in all regions. Remarkably, pain perception differs between regions, and pain intensity is lower in Africa than in other regions.

Abstract
The aim of this study was to investigate the characteristics of headache in patients with Behçet's disease (BD) seeking neurological consultation. Consecutive patients with BD seen within 1 year at the neuro-Behçet's out-patient clinic were studied using an electronic database according to the classification criteria of the International Headache Society. During a 12-month period 118 BD patients were admitted, and 98 had headaches. Migraine was the most common type of primary headache diagnosed in 45 patients (46.4%) in the whole headache group, followed by tension-type headache (TTH) in 26 cases (26.8%). Thirty-seven patients had secondary headaches mainly due to cerebral venous thrombosis or parenchymal neurological involvement of BD. Of these patients, 15 had both primary and secondary headaches. The primary headaches of 13 patients were exacerbated with systemic BD flare-ups, and four patients had migraine attacks triggered only by systemic BD activation which showed a good response to the treatment of systemic inflammation. The majority of the headaches of patients with BD do not indicate any neurological involvement; they are usually due to migraine or TTH. In a minority of patients, migraine associated with systemic inflammation of BD is notable.

Abstract
The aim of this study was to delineate any dysfunction of neuromuscular transmission (NMT) by single-fibre electromyography (SFEMG) in some rare types of migraine. Recent studies have shown subclinical dysfunction of NMT in migraine with aura and cluster headache by using SFEMG, whereas another recent study has shown NMT to be normal in familial hemiplegic migraine (FHM) with CACNA1A mutations. Thirty patients with rare primary headache syndromes [18 with sporadic hemiplegic migraine (SHM), six with FHM and six with basilar-type migraine (BM)] and 15 healthy control subjects without any headache complaints underwent nerve conduction studies, EMG and SFEMG during voluntary contraction of the extensor digitorum communis muscle. Ten to 20 different potential pairs were recorded and individual jitter values calculated. The results obtained from patient groups were compared with those from the normal subjects. Of 600 individual jitter values of the patients, 27 (4.5%) were abnormally high, whereas only 3/205 (1.5%) jitter values from normal subjects were abnormal. Abnormal NMT was found in 4/30 (13.3%) patients (three SHM and one BM), but in none of the control subjects. Only in SHM patients was the number of individual abnormal jitter values slightly but significantly different from normal controls. The present study demonstrates that subclinical NMT abnormality is slightly present in only SHM and BM patients, but not in FHM patients.

Abstract
The aim was to investigate neuromuscular transmission (NMT) by single-fibre EMG (SFEMG) in a large series of patients having migraine with aura (MA) or cluster headache (CH). Recent studies using SFEMG have shown subclinical dysfunction of NMT in MA and CH. Forty-three patients having MA, 51 with CH and 38 healthy control subjects underwent nerve conduction studies, EMG and SFEMG during voluntary contraction of the extensor digitorum communis muscle. Twenty different potential pairs were recorded and individual, mean and total abnormal individual jitter values were calculated. The results obtained from MA patients were compared with those from CH patients. In MA patients, 32 of 860 jitters were abnormally high, whereas 73 of 1020 of the jitters showed this abnormality in CH patients. None of the control subjects, five MA patients (11.6%) and 11 CH patients (21.6%) were designated as having subclinical NMT abnormality. Thus, patients having junction dysfunction were significantly more common in the CH group. The subclinical NMT abnormality shown by SFEMG is more common in CH than in MA. These two primary headache syndromes may have some shared functional abnormality of NMT constituents which is more evident in CH.

Abstract
Mesial temporal sclerosis (MTS) is the most frequent cause of drug resistant symptomatic partial epilepsy. The mechanism and genetic background of this unique pathology are not well understood. Aquaporins (AQP) are regulators of water homeostasis in the brain and are expressed in the human hippocampus. We explored the role of AQP genes in the pathogenetic mechanisms of MTS through an evaluation of gene expression in surgically removed human brain tissue. We analyzed AQP1 and 4 mRNA levels by quantitative real-time polymerase chain reaction and normalized to ABL and cyclophilin genes, followed by immunohistochemistry for AQP4. Relative expressions were calculated according to the delta Ct method and the results were compared using the Mann-Whitney U test. Brain specimens of 23 patients with epilepsy who had undergone surgery for MTS and seven control autopsy specimens were investigated. Clinical findings were concordant with previous studies and 61% of the patients were seizure-free in the postoperative period. AQP1 and 4 gene expression levels did not differ between MTS patients and control groups. Immunofluorescence analysis of AQP4 supported the expression results, showing no difference. Previous studies have reported contradictory results about the expression levels of AQP in MTS. To our knowledge, only one study has suggested upregulation whereas the other indicated downregulation of perivascular AQP4. Our study did not support these findings and may rule out the involvement of AQP in human MTS.

Abstract
PURPOSE In a recent genome-wide association study for partial epilepsies in the European population, a common genetic variation has been reported to affect partial epilepsy only modestly. However, in complex diseases such as partial epilepsy, multiple factors (e.g. single nucleotide polymorphisms, microRNAs, metabolic and epigenetic factors) may target different sets of genes in the same pathway, affecting its function and thus causing the disease development. In this regard, we hypothesize that the pathways are critical for elucidating the mechanisms underlying partial epilepsy. METHODS Previously we had developed a novel methodology with the aim of identifying the disease-related pathways. We had combined evidence of genetic association with current knowledge of (i) biochemical pathways, (ii) protein-protein interaction networks, and (iii) the functional information of selected single nucleotide polymorphisms. In our present study, we apply this methodology to a data set on partial epilepsy, including 3445 cases and 6935 controls of European ancestry. RESULTS We have identified 30 overrepresented pathways with corrected p-values smaller than 10(-12). These pathways include complement and coagulation cascades, cell cycle, focal adhesion, extra cellular matrix-receptor interaction, JAK-STAT signaling pathway, MAPK signaling pathway, proteasome, ribosome, calcium signaling and regulation of actin cytoskeleton pathways. Most of these pathways have growing scientific support in the literature as being associated with partial epilepsy. We also demonstrate that different factors affect distinct parts of the pathways, as shown here on complement and coagulation cascades pathway with a comparison of gene expression vs. genome-wide association study. CONCLUSIONS Traditional studies on genome-wide association have not revealed strong associations in epilepsies, since these single nucleotide polymorphisms are not shared by most of the patients. Our results suggest that it is more effective to incorporate the functional effect of a single nucleotide polymorphism on the gene product, protein-protein interaction networks and functional enrichment tools into genome-wide association studies. These can then be used to determine leading molecular pathways, which cannot be detected through traditional analyses. We hope that this type of analysis brings the research community one step closer to unraveling the complex genetic structure of epilepsies.

Abstract
Photoparoxysmal response (PPR) is considered to be a risk factor for idiopathic generalised epilepsy (IGE) and it has a strong genetic basis. Two genome-wide linkage studies have been published before and they identified loci for PPR at 6p21, 7q32, 13q13, 13q31 and 16p13. Here we combine these studies, augmented with additional families, in a mega-analysis of 100 families. Non-parametric linkage analysis identified three suggestive peaks for photosensitivity, two of which are novel (5q35.3 and 8q21.13) and one has been found before (16p13.3). We found no evidence for linkage at four previously detected loci (6p21, 7q32, 13q13 and 13q31). Our results suggest that the different family data sets are not linked to a shared locus. Detailed analysis showed that the peak at 16p13 was mainly supported by a single subset of families, while the peaks at 5q35 and 8q21 had weak support from multiple subsets. Family studies clearly support the role of PPR as a risk factor for IGE. This mega-analysis shows that distinct loci seem to be linked to subsets of PPR-positive families that may differ in subtle clinical phenotypes or geographic origin. Further linkage studies of PPR should therefore include in-depth phenotyping to make appropriate subsets and increase genetic homogeneity.

Abstract
Migraine is more likely to be misdiagnosed in patients with comorbid diseases. Not only primary care physicians, but also specialists might misdiagnose it due to the lack of diagnostic criteria awareness. The ID migraine test is a reliable screening instrument that may facilitate and accelerate migraine recognition. This study aimed to compare the prevalence and characteristics of migraine in a large sample of patients admitted to clinics of ophthalmology (OC), ear, nose and throat diseases (ENTC) and neurology (NC), as well as to validate the use of the ID migraine test in OC and ENTC settings. This was a multicentre (11 cites) study of out-patients admitting either to NC, ENTC or OC of the study sites during five consecutive working days within 1 week. From each of the clinics, 100 patients were planned to be recruited. All recruited patients were interviewed and those having a headache complaint received an ID migraine test and were examined for headache diagnosis by a neurologist, blinded to the ID migraine test result. A total of 2625 subjects were recruited. Only 1.3% of OC patients and 5.4% of ENTC patients have been admitted with a primary complaint of headache, whereas the percentage of NC patients suffering from headache was 37.6%. Whereas 138 patients (19.3%) in OC, 154 (17.3%) in ENTC and 347 (34%) in NC were found to be ID migraine test positive, 149 patients (20.8%) in OC, 142 (16%) in ENTC and 338 (33.1%) in NC were diagnosed with migraine. The sensitivity, specificity, and positive and negative predictive ratios of the ID migraine test were found to be similar in all clinics. An important fraction of the patients admitted to NC, as well as to OC and ENTC, for headache and/or other complaints were found out to have migraine by means of a simple screening test. This study validated the ID migraine test as a sensitive and specific tool in OC and ENTC, encouraging its use as a screening instrument.

Abstract
OBJECTIVE Our aim was to assess the long-term follow-up of juvenile myoclonic epilepsy (JME), with an emphasis on the course of the myoclonic seizures. METHODS We enrolled 48 patients with JME (29 F, 19 M; aged 39.9 +/- 9.5 years) followed up for a mean of 19.6 +/- 5.7 years. The remission for 5 years and relapses were evaluated for all seizure types and the changes in severity/frequency of myoclonia were systematically questioned. The clinical and EEG features, antiepileptic drug (AED) treatment regimen, and systemic and psychiatric comorbid diseases were evaluated. RESULTS We found a benign course in 66.6% whereas 16.7% had pseudo-resistance due to problems in treatment or lifestyle. The true-resistant course observed in the remaining 16.7% was significantly associated with psychiatric disorders and the presence of thyroid diseases. In 54.2% of the patients, myoclonia were in remission for a mean duration of 8.4 +/- 7.7 years, after an average age of 32.9 +/- 9.6. Of these patients, 6 were on a lower dose of AED in comparison to the dosage needed to control the seizures in the beginning, and 5 patients had stopped AED treatment. None of the latter 11 patients except one relapsed during the follow-up. Furthermore, 21 other patients (43.8%) described substantial alleviation after age 31.3 +/- 8.4 in the severity of myoclonia. CONCLUSION Although a great majority of the patients with juvenile myoclonic epilepsy had continuing seizures after a follow-up of 20 years, almost all had either 5-year remission or a substantial alleviation of the myoclonic seizures.

Abstract
OBJECTIVE The impact of migraine on physical, social, and emotional performance is considerable, yet it remains an underdiagnosed disorder. ID-Migraine is a validated migraine-screening tool developed to facilitate diagnosis. This study evaluated the validity and use of the Turkish version of the ID-Migraine screener (ID-Ms) in the workplace, and measured the impact of headache on disability, productivity, and quality of life among the workforce. METHODS A total of 465 employees from four companies were interviewed for screening with the ID-Ms. Subjects were included in the study if they reported two or more headaches in the past 3 months and gave a positive answer to one of the two ID-Ms prescreening questions. Eligible subjects completed the ID-Ms, the Migraine Disability Assessment Questionnaire, and the Medical Outcomes Study 36-Item Short Form Health Survey. Subjects were then evaluated for confirmation of their diagnosis according to the International Classification of Headache Disorders, 2nd edition (ICHD-2) criteria. RESULTS A total of 227 subjects (mean age 31.9 +/- 5.9 years; 65.6% women) completed the study. Migraine was diagnosed in 106 of the 227 subjects (46.7%) according to the ID-Ms and in 117 of the 227 subjects (51.5%) according to ICHD-2 criteria. The sensitivity of the ID-Ms was 70.9%, specificity was 79.1% and Cohen kappa value was 0.50. Workdays lost over the previous 3 months due to headache amounted to 8.7 +/- 9.5 days for migraine-positive and 4.9 +/- 6.6 days for migraine-negative subjects. CONCLUSION The Turkish version of the ID-Migraine screener is a valid tool for identifying subjects with migraine in the workplace.

Abstract
PURPOSE The goal of this study was to compare self-induction (SI) patterns in photosensitive epilepsy (PSE) and hot water epilepsy (HWE). METHODS Among 7609 consecutive patients, 129 were diagnosed as having PSE, and 34, HWE. RESULTS Thirteen patients with PSE (10 females, 3 males, age at onset: 8.6; 3 with mental retardation) and 9 patients with HWE (all males, age at onset: 13.1) reported experiencing SI. During the seizures, a pleasurable feeling was described by all patients with HWE, but only by 3 patients with PSE. Patients with PSE induced their seizures by going very close to the TV screen or by waving their hands and blinking in front of the light sources. In the patients with HWE, seizures were precipitated by increasing the temperature of the water poured over the head or body. CONCLUSIONS Our results indicate that SI is more frequent in HWE, although this behavior was attributed mostly to PSE in previous studies.

Abstract
PURPOSE Our aim is to outline the clinical and electroencephalographic (EEG) features of patients with hot water epilepsy (HWE), a rare and unique form of reflex epilepsy. METHODS Twenty-one patients with HWE, seen in our clinic until 1999, were studied. Male outnumbered female subjects in a ratio of 3:1. The age at the onset of seizures ranged from 19 months to 27 years (mean age at onset, 12 years). RESULTS The main factors precipitating seizures were bathing with hot water and/or pouring water over the head. Six patients reported self-induction, either by increasing the heat or the amount of water and/or recalling earlier bathing experiences. Nine patients expressed feeling pleasure during the seizures. Twenty patients had partial seizures, eight of whom also had secondarily generalized seizures. One patient had apparent generalized seizures only. Spontaneous seizures were present in 62% of the cases. Interictal epileptogenic abnormalities were documented in the EEGs of eight patients; the other eight had normal EEGs. The major sites of epileptogenic activity were over the unilateral temporal regions (in 40% of patients). Neuroimaging studies available for 12 patients (four cranial computed tomography and eight cranial magnetic resonance imaging scans) revealed normal findings. Seizure control in patients who were followed up was achieved by reducing the temperature or the duration of the bath or shower; several of the patients required medication. CONCLUSIONS The major findings of this study are that HWE has a male preponderance, can be self-induced, is often done for pleasure, has complex triggering factors, and shows temporally located abnormalities in the EEGs. Although HWE is generally known to be self-limited, antiepileptic drug treatment may sometimes be necessary to control seizures. Hot water epilepsy should be classified separately among the epileptic syndromes.

Abstract
We present the clinical and video-EEG data on an epileptic boy whose absence seizures with marked perioral movements had started at the age of 1.5 years. From age 12 years, he experienced frequent episodes of typical absence status epilepticus (ASE) lasting 1-2 hours with marked perioral myoclonia and moderate confusion. Initial therapy with carbamazepine was substituted by valproate because of worsening of the absence seizures. At the age of 17, the patient was admitted to our clinic with his usual, but long lasting ASE attack, accompanied by 2 generalized tonic-clonic convulsions. ASE was confirmed with the EEG which showed continuous 3 Hz spike and wave paroxysms with occasional normal intervals of 1-5 seconds. IV injection of clonazepam improved the clinical and EEG findings immediately. Video- EEG examination performed after a few weeks demonstrated typical absence seizures with perioral myoclonia. Based on the characteristics of seizure semiology, other clinical data and EEG findings, the patient was diagnosed as having the syndrome of "perioral myoclonia with absence seizures" described by Panayiotopoulos.

Abstract
In this retrospective study 67 patients with SSPE seen between the years 1980 and 1998 were reviewed. Using the criteria of SSPE diagnosis (clinical signs, characteristic EEG patterns, high titres of measles antibodies in the serum and CSF), the patients were divided into two groups. Group A fulfilled all criteria, however, due to the inability of measuring measles antibody before 1987, it was not possible to observe the third criterion in Group B. Among 67 patients, groups A and B consisted of 51 boys and 16 girls ranging in age between 1 to 23 years, mean age 13.1. The male/female ratio was 3.1. The periodic EEG complexes (PCs) were usually bilateral, synchronous and symmetrical. PC amplitude asymmetry was seen in 12 patients and 2 patients had no PC synchronization between the hemispheres. Six patients had more than one form of PC. Delta activity in anterior hemispheres after PC was seen in 40 patients, mostly in stage 2A. Thirty-two patients had focal epileptiform abnormalities in multiple locations at every stage but most frequently in frontal, central and temporal regions. One patient had PC over both hemispheres and periodic lateralized epileptiform discharges (PLEDs) over the right hemisphere. The EEG findings described and observed in our study do not seem to be specific to SSPE but these findings were not atypical or unusual.

Abstract
Among three recognised clinical phenotypes, type 3a Gaucher's disease is characterised by mild to severe systemic disease, neurological manifestations and myoclonic seizures. We report the long term clinical and electrophysiological follow-up of a 27-year old man with a diagnosis of type 3a Gaucher's disease, which was confirmed by bone marrow biopsy examination and leukocyte glucocerebrosidase level measurement. His neurological examination was normal throughout the follow-up period. EEG examination, recorded five days after the first seizure, revealed generalised nonrhythmic paroxysmal rapid spikes with occipital predominance increased by photic stimulation and normal background activity. The frequency of seizures increased from 3-4/year to 1-2/month within a follow-up period of 12 years and a repeat EEG examination on the eight year of diagnosis revealed additional background slowing. A giant potential was obtained in somatosensory evoked potential (SEP) examination. EEG findings of this case demonstrate a specific pattern with rapid spike activity, photosensitivity, eye closure sensitivity and gradual background slowing.

Abstract
The clinical features and EEGs of 45 consecutive patients (40 adults and 5 children) who had periodic lateralized epileptiform discharges (PLEDs) were reviewed to determine the relationship between seizures and PLEDs. Focal encephalitis and ischemic stroke were the most frequent underlying processes for adult patients. All of the children, but only six of the adults, had long-lasting cerebral disorders whereas the remaining adults had acute or subacute illness. There were 38 patients (84.4%) experiencing a seizure disorder. Twenty-six of them had their first seizure during their acute illness, as the pattern of PLED was encountered. Eight cases had status epilepticus, and seven of them had epilepsia partialis continua. Nineteen patients had a recent seizure in the day when PLEDs were observed but not during EEG recording; 12 patients had their seizures within 10 days before the observation of PLED. PLEDs were grouped into three categories with respect to their extensions: lateralized to one hemisphere (n = 22), localized in one region (n = 17) and being prominent over one side with contralateral spread (n = 6). The last group was found to be more closely associated with frequent seizures or status epilepticus than the other two groups. Our results showed that PLEDs were highly correlated with recent seizures in the majority of the patients. These EEG findings may be considered as a manifestation of an increased neuronal excitability caused by different etiologies; but not an ictal pattern.

Abstract
Nose wiping is a well-known postictal automatism in complex partial seizures, considered very important for lateralization. We report a 24-year-old woman selected from 32 patients with video-EEG investigations of absence seizures. The patient, with normal examination and imaging findings, had typical absence seizures from the age of 5 years, which were controlled with either ethosuximide or valproate and worsened by carbamazepine. In two of her recorded typical absence seizures associated with generalized 3 Hz symmetric spike-wave discharges, she wiped her nose as an automatism in the ictal and post-ictal period. Our case showed that nose wiping could be associated with generalized seizures, in contrast to other recent reports.
