Abstract
OBJECTIVE The neural correlates of creativity are not well understood. Using an improvised guitar task, we investigated the role of Broca's area during spontaneous creativity, regardless of individual skills, experience, or subjective feelings. RESULTS Twenty guitarists performed improvised and formulaic blues rock sequences while hemodynamic responses were recorded using functional near-infrared spectroscopy. We identified a new significant response in Broca's area (Brodmann area [BA] 45L) and its right hemisphere homologue during improvised playing but not during formulaic playing. Our results indicate that bilateral BA45 activity is common during creative processes that involve improvisation across all participants, regardless of subjective feelings, skill, age, difficulty, history, or amount of practice. While our previous results demonstrated that the modulation of the neural network according to the subjectively experienced level of creativity relied on the degree of deactivation in BA46L, our current results independently show a common concurrent activity in BA45 in all participants. We suggest that this is related to the sustained execution of improvisation in "motor control," analogous to motor planning in speech control.

Abstract
BACKGROUND Real-world data on the effectiveness of calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) in migraine patients are needed. METHODS We performed a single-center, real-world study with an observation period of up to 12 months (mean 7.5 ± 3.4 months) after CGRP mAb administration. A total of 228 Japanese patients with episodic or chronic migraine (age, 45.9 ± 13.2 years; 184F; 45 erenumab; 60 galcanezumab; 123 fremanezumab) who were treated with CGRP mAbs for at least three months were ultimately included in this study. RESULTS In the total cohort, after CGRP mAb treatment, mean monthly migraine days decreased by 7.2 ± 4.8, 8.3 ± 4.7, and 9.5 ± 5.0 at three, six and 12 months, respectively. The ≥50% monthly migraine day reduction rates at three, six and 12 months were 48.2%, 61.0% and 73.7%, respectively. In the logistic regression analysis, the presence of osmophobia and fewer baseline monthly migraine days contributed to ≥50% responders at three, six and 12 months. The ≥50% responders at three or six months were useful in predicting ≥50% responders at 12 months. In subgroups of patients with difficult-to-treat migraine (those with medication overuse headache or psychiatric comorbidities) and previous CGRP mAb users, monthly migraine days were substantially reduced over 12 months. There was no difference in monthly migraine day reduction over 12 months among three different CGRP mAbs. Adverse reactions were observed in 28 (12.3%) patients, with injection site reactions being the most common (n = 22) though generally mild in severity. CONCLUSION This real-world study confirmed the efficacy and safety of three different CGRP mAbs for prophylactic treatment of patients with migraine.

Abstract
Objectives Migraine is a disease that leads to social loss due to a decrease in productivity since it is a primary headache with a high prevalence and readily occurs in working-age persons. As described in the diagnostic criteria of the International Classification of Headache Disorders, 3rd edition (beta version), migraine causes hypersensitivity, especially photosensitivity, during attacks, suggesting that light is an inducer of headaches. We developed Blue Cut for Night (BCN) glass, which reduces light stimulation to intrinsically photosensitive continental ganglion cells (ipRGCs), photoreceptors that can lead to exacerbation of migraine attacks. Methods Ten patients with migraine participated in the study. Each participant was made to wear BCN glasses only at night for four weeks. The number of headache days and Headache Impact Test-6 values before and after using the BCN glasses were compared. Results When the 10 patients with migraine wore the BCN glass at night only for 4 weeks, the number of headache days within that time tended to decrease (7.0±4.37 days) compared to before wearing the glasses (8.7±5.03 days). No participants had any side effects. Conclusion BCN glass, which reduces light stimulation to ipRGCs, was suggested to be a tool for reducing migraine attacks.

Abstract
OBJECTIVE To investigate the relationship between weather and headache occurrence using big data from an electronic headache diary smartphone application with recent statistical and deep learning (DL)-based methods. BACKGROUND The relationship between weather and headache occurrence remains unknown. METHODS From a database of 1 million users, data from 4375 users with 336,951 hourly headache events and weather data from December 2020 to November 2021 were analyzed. We developed statistical and DL-based models to predict the number of hourly headache occurrences mainly from weather factors. Temporal validation was performed using data from December 2019 to November 2020. Apart from the user dataset used in this model development, the physician-diagnosed headache prevalence was gathered. RESULTS Of the 40,617 respondents, 15,127/40,617 (37.2%) users experienced physician-diagnosed migraine, and 2458/40,617 (6.1%) users had physician-diagnosed non-migraine headaches. The mean (standard deviation) age of the 4375 filtered users was 34 (11.2) years, and 89.2% were female (3902/4375). Lower barometric pressure (p < 0.001, gain = 3.9), higher humidity (p < 0.001, gain = 7.1), more rainfall (p < 0.001, gain = 3.1), a significant decrease in barometric pressure 6 h before (p < 0.001, gain = 11.7), higher barometric pressure at 6:00 a.m. on the day (p < 0.001, gain = 4.6), lower barometric pressure on the next day (p < 0.001, gain = 6.7), and raw time-series barometric type I (remaining low around headache attack, p < 0.001, gain = 10.1) and type II (decreasing around headache attack, p < 0.001, gain = 10.1) changes over 6 days, were significantly associated with headache occurrences in both the statistical and DL-based models. For temporal validation, the root mean squared error (RMSE) was 13.4, and the determination coefficient (R2 ) was 52.9% for the statistical model. The RMSE was 10.2, and the R2 was 53.7% for the DL-based model. CONCLUSIONS Using big data, we found that low barometric pressure, barometric pressure changes, higher humidity, and rainfall were associated with an increased number of headache occurrences.

Abstract
Objective Sensory hypersensitivities such as photophobia, phonophobia, and osmophobia are common in patients with migraine. We investigated the burden of these multiple sensory hypersensitivities in migraine. Methods In this cross-sectional study, 187 consecutive patients with migraine (26 men/161 women; age, 45.9 ± 13.2 years) were included. Sensory hypersensitivity symptoms such as photo−/phono−/osmophobia and accompanying symptoms were determined by neurologists in interviews. The Migraine Disability Assessment (MIDAS) was used to assess headache-related disability. The Kessler Psychological Distress Scale (K6) was also administered. Results Photophobia, phonophobia and osmophobia were observed in 75.4%, 76.5% and 55.1% of the patients with migraine, respectively. A significant overlap in sensory hypersensitivities (photo−/phono−/osmophobia) was found; the proportions of patients with 2 and 3 coexisting sensory hypersensitivities were 33.2% and 41.7%, respectively. The MIDAS score was higher in those with 3 sensory hypersensitivity symptoms than in those with 0 to 2 sensory hypersensitivity symptoms. A generalized linear model with ordinal logistic regression analysis revealed that multiple sensory hypersensitivities, younger age, more migraine days per month, and a higher K6 score were significantly related to the higher MIDAS score. Conclusion Our study showed that sensory hypersensitivities commonly occur and overlap in patients with migraine and that multiple sensory hypersensitivity symptoms have a significant impact on headache-related disability.

Abstract
To clarify whether photoreception of intrinsically photosensitive retinal ganglion cells (ipRGCs) is related to migraine, we investigated the relationship between hemodynamic responses related to neural activity and visual stimulation of ipRGCs. It has been established that photoreception in ipRGCs is associated with photophobia in migraine. However, the relationship between visual stimulation of ipRGCs and hemodynamic responses in the visual cortex has not been clarified. Hemodynamic responses in the visual cortex were measured using functional near-infrared spectroscopy (fNIRS) as signals reflecting changes in oxygenated and deoxygenated hemoglobin concentrations. Different types of visual stimulation generated by a metamerism method were applied to the peripheral field of the eye of patients with migraine (N = 20) and healthy participants (N = 21). The stimulation intensity on the retina was controlled using an artificial pupil. In the primary visual cortex of patients with migraine, statistically significant changes in fNIRS signals dependent on visual stimulation intensity applied to ipRGCs were observed (p < 0.01), while no such changes were observed in healthy participants. These results reveal that visual stimulation of ipRGCs projecting to the primary visual cortex is involved in hemodynamic responses in patients with migraine, suggesting that ipRGCs, in addition to photometric values related to cones, are associated with migraine.

Abstract
Objective Sound hypersensitivity is highly comorbid with migraine headaches. To elucidate the pathogenic mechanism of migraine attacks, we must first identify the types of everyday environmental sounds they perceive as unpleasant and clarify the acoustic properties of such sounds. This study aimed to clarify the true nature of "noise," i.e. everyday sounds perceived as unpleasant by migraineurs, by evaluating their subjective comfort/discomfort in response to several sounds commonly heard in everyday life. Methods Participants were presented with 20 environmental sounds they would likely hear daily. Subjects rated the pleasantness/unpleasantness of each stimulus using a nine-step scale. Patients We recruited 50 adults with migraine headaches (46 women, 4 men) and 50 healthy controls (35 women, 15 men). Results Migraineurs provided statistically significantly lower (more unpleasant) ratings to ambulance sirens, police car sirens, and railroad crossing bells than did controls. Our analysis also investigated the acoustic characteristics associated with higher rating gaps between the two groups. Greater divergence in ratings for the same stimulus was associated with less power (smaller amplitude envelope) and slower temporal variation in signals in the 400-Hz band. Conclusion We identified specific signal components associated with different subjective (un) pleasantness scores between migraineurs and healthy adults, which may lead to the elucidation of the pathogenic mechanism underlying migraine attacks triggered by sound.

Abstract
BACKGROUND The Parkinson's Disease Sleep Scale (PDSS)-2 is a recently developed tool for evaluating disease-related nocturnal disturbances in patients with Parkinson's disease (PD). However, its cutoff score has not been clinically assessed. We determined the optimal cutoff score of the Japanese version of the PDSS-2. METHODS Patients with PD (n = 146) and controls (n = 100) completed the PDSS-2 and the Pittsburgh Sleep Quality Index (PSQI). Poor sleepers were defined as having global PSQI scores >5. Optimal cutoff scores for determining poor sleepers were assessed using the receiver operating characteristic curve. RESULTS A PDSS-2 total score ≥ 14 exhibited 82.0% sensitivity and 70.6% specificity, whereas a PDSS-2 total score ≥ 15 provided 72.1% sensitivity and 72.9% specificity in distinguishing poor sleepers (PSQI score >5) from good sleepers (PSQI ≤ 5). Nocturnal disturbances were more frequently observed in patients with PD than in controls (PDSS-2 total score ≥ 14 or ≥ 15; 51.4% vs 20%; 45.9% vs 19%). Nocturnal disturbances were associated with higher Hoehn and Yahr stages and Unified Parkinson's Disease Rating Scale motor scores, impaired quality of life, daytime sleepiness, and depressive symptoms. CONCLUSION We suggest that PDSS-2 total scores ≥ 15 are useful for detecting poor sleepers among patients with PD.

Abstract
INTRODUCTION Dr. C. Miller Fisher described the appearance of unilateral facial palsy after resolution of ataxia in a patient with the eponymic Miller Fisher syndrome (MFS). However, there have been very few reports of delayed appearance of facial weakness in Guillain-Barré syndrome (GBS) and MFS when the other neurological signs reached nadir or started improving. METHODS In this study we reviewed the clinical and laboratory findings of consecutive patients with GBS (n=195) and MFS (n=68). RESULTS Delayed facial weakness occurred in 12 (6%) GBS and 4 (6%) MFS patients and was unilateral in 5 (42%) GBS and 2 (50%) MFS patients. In those patients with delayed facial weakness, neither limb weakness nor ataxia progressed, and facial weakness disappeared without immunotherapy. CONCLUSIONS Because facial weakness can lead to further morbidity, it would be prudent for clinicians to warn patients of this possibility, although additional immunotherapy is usually not required.

Abstract
Background Increasing evidence provides a clear association between rapid eye movement sleep behavior disorders (RBD) and Parkinson’s disease (PD), but the clinical features that determine the co-morbidity of RBD and PD are not yet fully understood. Methods We evaluated the characteristics of nocturnal disturbances and other motor and non-motor features related to RBD in patients with PD and the impact of RBD on their quality of life. Probable RBD (pRBD) was evaluated using the Japanese version of the RBD screening questionnaire (RBDSQ-J). Results A significantly higher frequency of pRBD was observed in PD patients than in the controls (RBDSQ-J ≥ 5 or ≥ 6: 29.0% vs. 8.6%; 17.2% vs. 2.2%, respectively). After excluding restless legs syndrome and snorers in the PD patients, the pRBD group (RBDSQ-J≥5) showed higher scores compared with the non-pRBD group on the Parkinson’s disease sleep scale-2 (PDSS-2) total and three-domain scores. Early morning dystonia was more frequent in the pRBD group. The Parkinson’s Disease Questionnaire (PDQ-39) domain scores for cognition and emotional well-being were higher in the patients with pRBD than in the patients without pRBD. There were no differences between these two groups with respect to the clinical subtype, disease severity or motor function. When using a cut-off of RBDSQ-J = 6, a similar trend was observed for the PDSS-2 and PDQ-39 scores. Patients with PD and pRBD had frequent sleep onset insomnia, distressing dreams and hallucinations. The stepwise linear regression analysis showed that the PDSS-2 domain “motor symptoms at night”, particularly the PDSS sub-item 6 “distressing dreams”, was the only predictor of RBDSQ-J in PD. Conclusion Our results indicate a significant impact of RBD co-morbidity on night-time disturbances and quality of life in PD, particularly on cognition and emotional well-being. RBDSQ may be a useful tool for not only screening RBD in PD patients but also predicting diffuse and complex clinical PD phenotypes associated with RBD, cognitive impairment and hallucinations.

Abstract
OBJECTIVE There are conflicting results regarding the frequency and clinical significance of sleep related breathing disorders in patients with Parkinson's disease (PD). The aim of this study was to investigate the relationship between snoring and its clinical correlates in patients with PD. METHODS A total of 93 PD patients and 93 controls were analyzed from a previously conducted cross-sectional study. Snoring was defined as a snoring frequency of ≥ 2 days/week (a score of 2 or higher on the PD Sleep Scale-2 subitem 15). Excessive daytime sleepiness (EDS) was defined as an Epworth Sleepiness Scale score of ≥ 10. RESULTS Snoring was more prevalent in the patients with PD than in the controls (14.0% vs. 1.1%). The PD patients who snored exhibited greater disease severity, worse scores on the motor section of the Unified Parkinson's Disease Rating Scale (UPDRS) and the Parkinson fatigue scale and more impaired scores in several domains of the Parkinson's Disease Questionnaire, including the domains of mobility, activities of daily living, emotional well-being, communication and bodily discomfort, when compared to those who did not snore. No between-group differences were found in EDS. A higher proportion of the UPDRS motor scores for bradykinesia was seen in the PD patients who snored compared to that observed in the PD patients who did not snore. CONCLUSION We found that snoring was more frequent in PD patients than in controls. Furthermore, snoring in PD patients was associated with disease severity, an impaired motor function and a decreased quality of life, although it was not associated with EDS.

Abstract
OBJECTIVE There are many reports regarding the course of migraines during pregnancy. However, the prevalence and characteristics of migraines during the postpartum period have not been adequately investigated. We prospectively investigated the patients suffering from migraines over a long postpartum period in an obstetrics department in Japan. METHODS We investigated the course of migraines experienced during the postpartum period by patients in a postnatal ward. The patients were surveyed during the first postpartum week and 1, 3, 6 and 12 months after delivery. The patients were provided a headache diary to assess medication use and migraine attack frequency, severity (the faces pain scale) and duration. RESULTS The migraine remission rate was 63%, 83% and 85% during the first, second and third trimesters, respectively. No patient experienced a worsening of headaches during pregnancy. Headache recurrence during the first month after delivery was more frequent in the patients >30 years of age than in those ≤30 years of age (p<0.05). The percentage of women experiencing recurrence at 1, 3, 6 and 12 months after delivery was 63%, 75%, 78% (n=60) and 87.5% (n=40), respectively. In breastfeeding patients, the rates were 50%, 65.8%, 71.1% and 91.7% and in bottle feeding patients, the rates were 86.4%, 90.9%, 95.5% and 81.3%, respectively. CONCLUSION We found that 85% of the patients with migraines experience remission during pregnancy and that more than 50% experience recurrence during the first month after delivery. Until six months after delivery, breastfeeding is associated with a lower recurrence rate than bottle feeding.

Abstract
AIMS Peculiar characteristics of migraine headaches include the arousal of olfaction during the attacks and osmophobia. We performed an olfactory test to evaluate the association between olfaction and migraines. METHODS We evaluated olfactory dysfunction in 80 migraine patients (31 experienced migraines with aura (MWA), 49 migraine without aura (MWOA)) and 30 healthy controls. Participants were assessed for concurrent osmophobia. Olfaction was evaluated using an odour stick identification test (OSIT), in which participants were asked to identify various odours during a migraine-free period. The degree of offensiveness of each odour was also evaluated. RESULTS Sixty-three percent of migraine patients were found to have concurrent osmophobia (MWA 71%; MWOA 57%). The percentages of migraine patients and controls who correctly identified test odours were 91% (92%, MWA; 89%, MWOA) and 92%, respectively. Perfume, rose and Japanese cypress odours were more offensive to migraine patients than to controls. All test odours were found to be more offensive to MWA than to MWOA patients. CONCLUSIONS The OSIT showed certain odours to be highly offensive to migraine patients even when they were not experiencing migraine headaches. More attention should be paid to odours that are perceived to be offensive by migraine patients, particularly those with MWA.

Abstract
OBJECTIVE Barometric pressure has been reported as a triggering and exacerbating factor in migraine headaches, although there are few reports concerning the association of weather change and migraine headache. The relationship between barometric pressure changes and migraine headaches was prospectively examined. METHODS A total of 28 migraine patients who lived within 10 km of the Utsunomiya Local Meteorological Observatory kept a headache diary throughout the year. Daily and monthly mean barometric pressure data of the Utsunomiya Local Meteorological Observatory were obtained via the homepage of the Meteorological Office. RESULTS The correlation between headache frequency obtained by the headache diaries for 1 year and changes in the barometric pressure during the period of 2 days before and 2 days after the headache onset were evaluated. The frequency of migraine increased when the difference in barometric pressure from the day the headache occurred to the day after was lower by more than 5 hPa, and decreased when the difference in barometric pressure from the day the headache occurred to 2 days later was higher by more than 5 hPa. Of 28 patients, weather change was associated with migraine headache development in 18 (64%) patients, 14 of which reported low barometric pressure to be a cause of headache. There was no association between the monthly mean barometric pressure and headache frequency throughout the year. CONCLUSION Barometric pressure change can be one of the exacerbating factors of migraine headaches.

Abstract
Measurements of the lead isotopic composition and the uranium, thorium, and lead concentrations in meteorites were made in order to obtain more precise radiometric ages of these members of the solar system. The newly determined value of the lead isotopic composition of Canyon Diablo troilite is as follows: (206)Pb/(204)Pb = 9.307, (207)Pb/(2O4)Pb = 10.294, and (208)Pb/(204)Pb = 29.476. The leads of Angra dos Reis, Sioux County, and Nuevo Laredo achondrites are very radiogenic, the (206)Pb/(204)Pb values are about 200, and the uranium-thorium-lead systems are nearly concordant. The ages of the meteorites as calculated from a single-stage (207)Pb/(206)Pb isochron based on the newly determined primordial lead value and the newly reported (235)U and (838)U decay constants, are 4.528 x 10(9) years for Sioux County and Nuevo Laredo and 4.555 x 10(9) years for Angra dos Reis. When calculated with the uranium decay constants used by Patterson, these ages are 4.593 x 10(9) years and 4.620 x 10(9) years, respectively, and are therefore 40 to 70 x 10(6) years older than the 4.55 x 10(9) years age Patterson reported. The age difference of 27 x 10(6) years between Angra dos Reis and the other two meteorites is compatible with the difference between the initial (87)Sr/(86)Sr ratio of Angra dos Reis and that of seven basaltic achondrites observed by Papanastassiou and Wasserburg. The time difference is also comparable to that determined by (129)1-(129)Xe chronology. The ages of ordinary chondrites (H5 and L6) range from 4.52 to 4.57 x 10(9) years, and, here too, time differences in the formation of the parent bodies or later metamorphic events are indicated. Carbonaceous chondrites(C2 and C3) appear to contain younger lead components.

Abstract
The aim of this study was to investigate the prevalence and characteristics of typical aura without headache (TAWH) in Japan. We distributed a self-report questionnaire comprising seven items. Of 1914 cases, the number of patients who provided valid answers was 1063. They included 1063 out-patients with 81 of these patients positive in the ID migraine screener Japanese version. TAWH was diagnosed in 35 patients (3.2%), aged 23–87 years, and included 12 males and 23 females. The age of patients with TAWH showed a biphasic distribution (20–39 years and 60–69 years), similar to the age distribution of all patients. Migraine with aura was diagnosed in 67 patients (6.3%) and showed a monophasic age distribution (40–49 years). These data suggest that TAWH is not a rare headache type in clinics especially in a setting of general ophthalmology clinics, and some patients of migraine with aura may transform to TAWH with ageing.

Abstract
An 88-year-old female with atrial fibrillation and hypertension, was admitted to our hospital with sudden onset diplopia and somnolence. She had right hemiparesis with bilateral positive Babinski's sign. Additionally, there was bilateral blepharoptosis with right esotropia. With regard to extraocular movement, the patient demonstrated conjugate upgaze palsy and left monocular down gaze palsy (vertical one-and-a-half syndrome: VOHS). Horizontal gaze in the left eye was completely impaired and there was limited abduction of the right eye. Magnetic resonance imaging of the brain showed left thalamo-mesencephalic infarction. On day 4, the vertical eye movement developed into conjugate upgaze and down- gaze palsies. Magnetic resonance imaging of the brain indicated high signal lesion extending into the dorsal portion of the midbrain. It was suggested that the pathway to contralateral downgaze neurons could have been damaged due to the unilateral (left) dosal midbrain lesion before its decussation with the unilateral interstitial nucleus of Cajal, the oculomotor nucleus and the rostral interstitial nucleus of the medial longitudinal fasciculus. This case is considered to be important because there has been no previous report of bilateral vertical gaze palsy due to VOHS in the same patient. Since there are various patterns of ocular movement disorder in the thalamo-mesencephalic portion, careful observations are required to localize the lesions.

Abstract
OBJECTIVE Benzodiazepines are commonly used for the treatment of tension-type headache (TTH), however, there are few randomized controlled trials recommending the use of these drugs in Japan. This study was undertaken to evaluate the efficacy of etizolam, a thienodiazepine derivative, in combination with a non-steroidal anti-inflammatory drug (NSAID) as an acute treatment for TTH. METHODS The study design was a multi-center randomized control trial and included 144 patients. The diagnosis of TTH was based on the criteria of the International Classification of Headache Disorders-1 and all patients were diagnosed with episodic tension-type headache (ETTH). Changes in the severity of headache and shoulder pain were graded using a Visual Analogue Scale (VAS) before and after administration of drugs. Patients were randomized into NSAID alone (NSAID, mefenamic acid, 250 mg) group and NSAID (mefenamic acid, 250 mg) plus etizolam (0.5 mg) (NSAID-ET) group prior to treatment. RESULTS Although both groups showed a significant drop in VAS for headache and shoulder pain (p<0.01), there was no overall significant difference between the NSAID-ET and NSAID groups. However, headache was improved significantly in female patients (p<0.05), and shoulder pain was improved in young and female patients (p<0.05, p<0.04) in the NSAID-ET group. CONCLUSION This study indicates that the combination treatment of etizolam and NSAID is useful in young or female patients.

Abstract
The authors reported the neurological disease spectrum associated with autoantibodies against minor gangliosides GM1b and GalNAc-GD1a. IgG and IgM antibody reactivity against gangliosides GM1, GM2, GM1b, GD1a, GalNAc-GD1a and GQ1b was investigated in sera from 7000 consecutive patients who had various neurological conditions. The clinical diagnoses for 456 anti-GM1b-positive patients were Guillain-Barré syndrome (GBS, 71%), atypical GBS with preserved deep tendon reflexes (12%), Fisher syndrome (10%), Bickerstaff's brainstem encephalitis (2%), ataxic GBS (2%) and acute ophthalmoparesis (1%). For 193 anti-GalNAc-GD1a-positive patients, the diagnoses were GBS (70%), atypical GBS (16%), Fisher syndrome (10%) and Bickerstaff's brainstem encephalitis (3%). Of the patients with GBS or atypical GBS, 28% of 381 anti-GM1b-positive and 31% of 166 anti-GalNAc-GD1a-positive patients had neither anti-GM1 nor anti-GD1a antibodies. Of those patients with Fisher syndrome, Bickerstaff's brainstem encephalitis, ataxic GBS or acute ophthalmoparesis, 33% of 67 anti-GM1b-positive, and 52% of 25 anti-GalNAc-GD1a-positive patients had no anti-GQ1b antibodies. Autoantibodies against GM1b and GalNAc-GD1a are associated with GBS, Fisher syndrome and related conditions. These antibodies should provide useful serological markers for identifying patients who have atypical GBS with preserved deep tendon reflexes, ataxic GBS, Bickerstaff's brainstem encephalitis or acute ophthalmoparesis, especially for those who have no antibodies to GM1, GD1a or GQ1b. A method to prepare GM1b was developed.

Abstract
The authors reviewed clinical profiles and laboratory findings for 100 cases of abducens nerve paresis without impairment of the other cranial nerves, limb weakness, and ataxia throughout the clinical course. Review of the medical records of 9300 patients referred to our neuoroimmunological laboratory for serum anti-ganglioside antibody testing. Information was obtained from each primary physician on symptoms of preceding infection; initial symptoms; neurological signs during the illness; the clinical course; treatment provided; and outcome. Isolated abducens nerve paresis was present in 100 patients and bilateral paresis in 29. Tentative diagnoses made by the primary physicians on request of anti-ganglioside antibody testing were abducens nerve palsy (n = 68), Fisher syndrome (n = 14), acute ophthalmoparesis without ataxia (n = 14). Symptoms of infection anteceded in 63. Tendon reflexes were absent or decreased in 27. Distal paresthesias were experienced by seven. Serum anti-GQ1b antibody was positive in 25. These findings suggest that some cases of isolated abducens nerve palsy can be categorized as a regional variant of Guillain-Barré syndrome or mild form of Fisher syndrome.

Abstract
We investigated prevalence and character of primary headache for 2,462 examples of high school student. An overall headache prevalence was 41.0 in boys, 55.3% in girls, and average of the headache onset was 12.7 in boys, 12.9 in girls years old. A prevalence of migraine is 5.5 in boys, 6.1% in girls according to ICHD-I and 13.7 in boys, 17.5% in girls according to modified ICHD-II diagnosis criteria. For the tension type headache, it was 23.0 in boys, 30.6% in girls according to modified ICHD-I diagnosis criteria. High school students with primary headache tend take painkillers easily, but are much less likely visit physicians (only 15.0%). Our data showed that the prevalence of headache especially migraine in Japanese high school student was almost similar to past world wide findings, and suggest that its impact on the quality of life can not be ignored. Therefore, headache education must be important and necessary in a high school.

Abstract
BACKGROUND Chronic inflammatory demyelinating polyneuropathy (CIDP) is a heterogeneous disorder and both clinical course and response to treatment vary widely. Because of the propensity for relapse, CIDP requires maintenance therapy after the initial response to treatment. There is no consensus regarding this in the published literature. PRESENT REPORT A patient with CIDP was treated with oral prednisolone and cyclophosphamide pulse therapy but required repeated plasma exchange and intravenous immunoglobulin (IVIg). Treatment with ciclosporin freed the patient from repeated IVIg administration. Therapeutic responses in 14 subsequent cases including three patients who showed improvement with ciclosporin are also presented along with an algorithm of the authors' suggested protocol for treatment. CONCLUSION Ciclosporin should be considered for patients with intractable CIDP who require repeated IVIg.

Abstract
Side effects were compared in 9 patients with Guillain-Barré syndrome treated with standard intravenous immunoglobulin (IVIg) only and in 9 treated with combined methylprednisolone and IVIg therapy. Headache occurred in 2 in both groups, indicative that pre-infusion with steroids does not prevent headache. Transient liver function disturbances were present in 2 patients of the former group and in 6 of the latter.

Abstract
To clarify the clinical features of patients with anti-GalNAc-GD1a antibody, we retrospectively investigated which conditions were associated with anti-GalNAc-GD1a antibody in a large number of patients. Sixty-four out of 1,713 patients had anti-GalNAc-GD1a IgG antibody. Fifty-seven (89%) were diagnosed with Guillain-Barré syndrome (GBS) or atypical GBS with preserved deep tendon reflexes. These patients were characterized by young man, antecedent diarrhea, distal-dominant limb weakness, and absence of cranial nerve impairment and sensory disturbance. Some of sera from patients had anti-GM1, anti-GM1b, and anti-GD1a IgG antibodies associated with axonal GBS. Our study suggests that the anti-GalNAc-GD1a antibody testing is useful for supporting the diagnosis of GBS. In addition, fine specificity of the antibody also was clarified.

Abstract
Ataxic Guillain-Barré syndrome (GBS) associated with anti-GQ1b IgG antibody has been reported. We, however, have had a patient with ataxic GBS who had IgG antibodies to the minor gangliosides GM1b and GalNAc-GD1a, and we therefore retrospectively investigated the clinical features of patients who had antibodies to GM1b or GalNAc-GD1a, but not to GQ1b. Information on patients' antecedent illnesses, initial symptoms, neurological signs, and CSF findings was reviewed in those with ataxic GBS or Fisher syndrome (FS) with anti-GM1b or anti-GalNAc-GD1a IgG antibodies. We tested whether the anti-GM1b and anti-GalNAc-GD1a antibodies are cross-reactive and constructed three-dimensional structural models of GM1b and GalNAc-GD1a. Ataxic GBS was diagnosed in 1 of 65 patients who had both anti-GM1b and anti-GalNAc-GD1a antibodies and in 3 of 159 patients who had anti-GM1b antibody without anti-GalNAc-GD1a antibody: FS was diagnosed in 1 of the 159 patients and in 1 of 35 who had anti-GalNAc-GD1a antibody without anti-GM1b antibody. All the patients' antibodies to GM1b or GalNAc-GD1a were associated with the IgG isotype. The clinical features of patients with ataxic GBS associated with anti-GM1b or anti-GalNAc-GD1a IgG antibodies did not differ from those of patients who had anti-GQ1b IgG antibody. Absorption study findings for serum from the patient who had both anti-GM1b and anti-GalNAc-GD1a IgG antibodies showed significant absorbance of anti-GM1b IgG antibody by GalNAc-GD1a and of anti-GalNAc-GD1a IgG antibody by GM1b, indicating that these antibodies are cross-reactive. This is the first report of ataxic GBS or FS associated with anti-GM1b or anti-GalNAc-GD1a IgG antibodies. These autoantibodies, as well as anti-GQ1b IgG antibody, may function in the development of some patients with ataxic GBS and FS.

Abstract
To clarify the clinical features of patients with anti-GM1b antibody, we retrospectively investigated which conditions were associated with anti-GM1b antibody in a large number of patients. Two hundred out of 1,713 patients had anti-GM1b antibody. One hundred and sixty-six (83%) were diagnosed with Guillain-Barré syndrome (GBS) or atypical GBS with preserved deep tendon reflexes. Our study suggests that the anti-GM1b antibody testing is useful for supporting the diagnosis of GBS. In addition, anti-GM1b antibody was detected in 18 patients with Fisher syndrome and the related conditions associated with anti-GQ1b IgG antibody, and 3 patients with ataxic GBS associated with anti-GD1b IgG antibody.

Abstract
The cross reactivity of anti-GM1 IgG antibody with various gangliosides and asialo-GM1 in serum samples from 27 patients with Guillain-Barré syndrome was investigated. An enzyme linked immunosorbent assay (ELISA) absorption study showed that anti-GM1 IgG antibody cross reacted with asialo-GM1 in 52% of the patients, GM1b in 41%, GD1b in 22%, and GalNAc-GD1a in 19%, and that it did not cross react with GM2, GT1b, or GQ1b. The antibody that cross reacted with GD1b was associated with a high frequency of cranial nerve involvement and negative Campylobacter jejuni serology. Anti-GM1 IgG antibody has a broad range of cross reactivity which may contribute to various clinical variations of Guillain-Barré syndrome.

Abstract
We evaluated the usefulness of the test tape for cerebrospinal fluid (CSF), with which glucose and protein were examined, in aid of rapid diagnosis of various neurological diseases. Twenty-eight patients were examined to estimate the level of CSF glucose and protein using test tape. The data accuracy was confirmed with the data from standard measurements because the data from test tape correlated significantly with the data measured by standard method (glucose, p < 0.05; protein, p < 0.01). The test tape is useful for the rapid examination of CSF. We hope that more accurate test tape method will be developed for CSF glucose and protein determination.

Abstract
Samarium-neodymium isotopic data on whole rocks and minerals of the Sudbury Complex in Canada gave an igneous crystallization age of 1840 +/- 21 x 10(6) years. The initial epsilon neodymium values for 15 whole rocks are similar to those for average upper continental crust, falling on the crustal trend of neodymium isotopic evolution as defined by shales. The rare earth element concentration patterns of Sudbury rocks are also similar to upper crustal averages. These data suggest that the Sudbury Complex formed from melts generated in the upper crust and are consistent with a meteoritic impact.

Abstract
The initial ratios of neodymium-143 to neodymium-144 in kimberlites ranging in age between 90 x 10(6) to 1300 x 10(6) years from South Africa, India, and the United States are different from the corresponding ratios in the minerals of peridotite inclusions in the kimberlites but are identical to the ratios in the basaltic achondrite Juvinas at the times of emplacement of the respective kimberlite pipes. This correlation between the kimberlites and Juvinas, which represents the bulk chondritic earth in rare-earth elements, strongly indicates that the kimberlite's source in the mantle is chondritic in rare-earth elements and relatively primeval in composition.

Abstract
Apollo 16 breccia 66095 contains a remarkably high amount of lead (15 parts per million), 85 percent of which is not supported by uranium and thorium in the rock. An acid leach experiment coupled with separate analyses of the whole rock and mineral fractions for uranium, thorium, and lead indicate that the excess lead has a lunar source and was apparently introduced about 4.0 x 10(9) years ago. The data also suggest that a major lunar crustal differentiation occurred about 4.47 x 10(9) years ago.

Abstract
Concentrations of U, Th, and Pb in Apollo 11 samples studied are low (U. 0.16 to 0.87; Th, 0.53 to 3.4; Pb, 0.29 to 1.7, in ppm) but the extremely radiogenic lead in samples allows radiometric dating. The fine dust and the breccia have a concordant age of 4.66 billion years on the basis of (207)Pb/(206)Pb, (206)Pb/(238)U, (207)Pb/(235U), and(208)Pb/(232)Th ratios. This age is comparable with the age of meteorites and with the age generally accepted for the earth. Six crystalline and vesicular samples are distinctly younger than the dust and breccia. The (238)U/(235)U ratio is the same as that in earth rocks, and (234)U is in radioactive equilibrium with parent (238)U.

Abstract
The isotopic compositions of lead and the concentrations lead, uranium, and thorium in samples of oceanic tholeiite and alkali suites are determined, and the genetic relations of the oceanic basalts are discussed. Lead of the oceanic tholeiites has a varying lead-206: lead-204 ratio between 17.8 and 18.8, while leads of the alkali basalt suites from Easter Island and Guadalupe Island are very radiogenic with lead-206: lead-204 ratios between 19.3 and 20.4 It is concluded that (i) the isotopic composition of lead in oceanic tholeiite suggests that the upper mantle source region of the tholeiite was differentiated from and original mantle material more than 1 billion years ago and that the upper mantle is not homogeneous at the present time, (ii) less than 20 million years was required for the crystal differentiation within the alkali suite from Easter Island, (iii) no crustal contamination was involved in the course of differentiation of rocks from Easter Island; however, some crustal contamination may have affected Guadalupe Island rocks, and (iv) alkali basalt may be produced from the tholeiite in the oceanic region by crystal differentiation. Alternatively the difference in the isotopic composition of lead in oceanic basalts may be produced by partial melting at different depths of a differentiated upper mantle.

Abstract
The average concentrations of potassium, rubidium, strontium, thorium, and uranium in oceanic tholeiitic basalt are (in parts per million) K, 1400; Rb, 1.2; Sr, 120; Th, 0.2; and U, 0.1. The ratio Sr(87) to Sr(86) is about 0.702, that of K to U is 1.4 x 10(4), and of Th to U is 1.8. These amounts of K, Th, U, and radiogenic Sr(87) are less than in other common igneous rocks. The ratios of Th to U and Sr(87) to Sr(86) suggest that the source region of the oceanic tholeiites was differentiated from the original mantle material some time in the geologic past.
