RESUMEN
Background@#and Purpose Patients with cluster headache (CH) exhibit impaired health-related quality of life (HRQoL). However, there have been few studies related to the HRQoL of patients with CH from Asian backgrounds. This study aimed to determine the impact of CH on HRQoL and to identify the factors affecting HRQoL in patients with CH during cluster periods. @*Methods@#This prospective study enrolled patients with CH from 17 headache clinics in South Korea between September 2016 and February 2021. The study aimed to determine HRQoL in patients with CH using the EuroQol 5 Dimensions (EQ-5D) index and the time trade-off (TTO) method. Age- and sex-matched headache-free participants were recruited as a control group. @*Results@#The study included 423 patients with CH who experienced a cluster period at the time. EQ-5D scores were lower in patients with CH (0.88±0.43, mean±standard deviation) than in the controls (0.99±0.33, p<0.001). The TTO method indicated that 58 (13.6%) patients with CH exhibited moderate-to-severe HRQoL deterioration. The HRQoL states in patients with CH were associated with current smoking patterns, headache severity, frequency, and duration, and scores on the Generalized Anxiety Disorder 7-item scale (GAD-7), Patient Health Questionnaire 9-item scale (PHQ-9), 6-item Headache Impact Test, and 12-item Allodynia Symptom Checklist. Multivariable logistic regression analyses demonstrated that the HRQoL states in patients with CH were negatively correlated with the daily frequency of headaches, cluster period duration, and GAD-7 and PHQ-9 scores. @*Conclusions@#Patients with CH experienced a worse quality of life during cluster periods compared with the headache-free controls, but the degree of HRQoL deterioration varied among them. The daily frequency of headaches, cluster period duration, anxiety, and depression were factors associated with HRQoL deterioration severity in patients with CH.
RESUMEN
Background@#Migraine patients have a higher frequency of suicidality than people without migraine. The aim of this study was to identify suicidality and its risk factors in migraine patients. @*Methods@#We enrolled 358 migraine patients from 11 hospitals. We collected data regarding their clinical characteristics and the patients completes the questionnaires. We also interviewed patients with the Mini International Neuropsychiatric Interview (MINI)plus version 5.0.0 to identify their suicidality. The International Classification of Headache Disorders, third edition, beta version was used in headache diagnosis. @*Results@#The frequency of suicidality in migraine patients was 118 (33.0%). Migraine patients with suicidality were more likely to have a major depressive disorder or generalized anxiety disorder than those without suicidality. Among variables, risk factors for suicidality in migraine patients were female (odds ratio [OR], 4.110; 95% confidence interval [CI], 1.55310.878; p=0.004), attack duration (OR, 2.559; 95% CI, 1.2105.413; p=0.011), Patient Health Questionnaire9 (OR, 1.111; 95% CI, 1.0381.189; p=0.002), and Generalized Anxiety Disorder7 (OR, 1.194; 95% CI, 1.1011.294; p<0.001). @*Conclusions@#Suicidality in migraine patients is common. Therefore, clinicians who take care of migraine patients should be concerned about suicidality and its risk factors such as female gender, attack duration, depression or anxiety.

Background@#and Purpose Epidemiologic data suggest that cluster headache (CH) is significantly associated with cigarette smoking. The aim of this study was to determine differences in features between patients with a smoking history and those who are never-smokers, using data from a prospective multicenter registry. @*Methods@#Data used in this study were obtained from the Korean Cluster Headache Registry that collected data from consecutive patients diagnosed with CH. We compared clinical and demographic features between ever-smokers (current or former smokers) and never-smokers. @*Results@#This study enrolled 250 patients who were diagnosed with CH, of which 152 (60.8%) were ever-smokers and 98 (39.2%) were never-smokers. The age at CH onset was significantly lower in the never-smoker group than in the ever-smoker group [27.1±12.9 years vs. 30.6± 10.9 years (mean±standard deviation), p=0.024]. Seasonal rhythmicity (58.1% vs. 44.7%, p= 0.038) and triptan responsiveness (100% vs. 85.1%, p=0.001) were higher in never-smokers, while other clinical features such as pain severity, duration, attack frequency, and associated autonomic symptoms did not differ significantly between the groups. The male-to-female ratio was markedly higher in ever-smokers (29.4:1) than in never-smokers (1.7:1). @*Conclusions@#Most of the clinical features did not differ significantly between patients with a smoking history and never-smokers. However, the age at CH onset, sex ratio, and seasonal rhythmicity were significantly associated with smoking history.

RESUMEN
Globally, migraine is the third most common disease affecting 1.3 billion people worldwide and the second leading cause of disability. With the recent advances in new drugs and device technology for the treatment of migraine, the Korean Headache Society (KHS) and American Headache Society (AHS) released a new practice guideline on the treatment of migraine in 2019, respectively. They developed their consensus statement after reviewing existing guidelines and recent clinical trials and having discussions with stakeholders. The KHS guideline addresses best practice for preventing migraine with oral treatments including start and stopping strategies. The AHS statement dealt with newer treatments, such as onabotulinumtoxinA, and the recently approved calcitonin gene-related peptide targeting agents, and nonpharmacological treatments such as neuromodulation and biobehavioral therapy for both preventive and acute treatment. In this paper, we will review and summarize updated guideline for migraine treatment.
RESUMEN
BACKGROUND AND PURPOSE: Cluster headache (CH) can present with migrainous symptoms such as nausea, photophobia, and phonophobia. In addition, an overlap between CH and migraine has been reported. This study aimed to determine the differences in the characteristics of CH according to the presence of comorbid migraine. METHODS: This study was performed using data from a prospective multicenter registry study of CH involving 16 headache clinics. CH and migraine were diagnosed by headache specialists at each hospital based on third edition of the International Classification of Headache Disorders (ICHD-3). We interviewed patients with comorbid migraine to obtain detailed information about migraine. The characteristics and psychological comorbidities of CH were compared between patients with and without comorbid migraine. RESULTS: Thirty (15.6%) of 192 patients with CH had comorbid migraine, comprising 18 with migraine without aura, 1 with migraine with aura, 3 with chronic migraine, and 8 with probable migraine. Compared to patients with CH without migraine, patients with CH with comorbid migraine had a shorter duration of CH after the first episode [5.4±7.4 vs. 9.0±8.2 years (mean±standard deviation), p=0.008], a lower frequency of episodic CH (50.0% vs. 73.5%, p=0.010), and a higher frequency of chronic CH (13.3% vs. 3.7%, p=0.033). Psychiatric comorbidities did not differ between patients with and without comorbid migraine. The headaches experienced by patients could be distinguished based on their trigeminal autonomic symptoms, pulsating character, severity, and pain location. CONCLUSIONS: Distinct characteristics of CH remained unchanged in patients with comorbid migraine with the exception of an increased frequency of chronic CH. The most appropriate management of CH requires clinicians to check the history of preceding migraine, particularly in cases of chronic CH.

BACKGROUND AND PURPOSE: Frovatriptan is a selective 5-HT1B/1D agonist with a long duration of action and a low incidence of side effects. Although several placebo-controlled trials have documented the clinical efficacy and safety of frovatriptan in adults with migraine, this drug has not previously been studied in Asian including Korean patients. METHODS: In this double-blind multicenter trial, 229 patients with migraine were randomized to receive frovatriptan 2.5 mg or placebo upon the occurrence of a moderate-to-severe migraine. The primary outcome was the 2-hour headache response rate. RESULTS: Frovatriptan significantly increased the 2-hour headache response rate compared with placebo (52.9% vs. 34.0%, p=0.004). The headache response rates at 4, 6, and 12 hours were significantly higher in the frovatriptan group than in the placebo group, as was the pain-free rate at 2 hours (19.0% vs. 5.7%, p=0.004), 4 hours (40.7% vs. 23.0%, p=0.006), and 6 hours (56.1% vs. 34.0%, p=0.002). The median time to a headache response was significantly shorter in the frovatriptan group than in the placebo group (2.00 hours vs. 3.50 hours, p<0.001). The use of rescue medications was more common in the placebo group (p=0.005). Chest tightness associated with triptan was infrequent (2.5%), mild, and transient. CONCLUSIONS: These results demonstrate that 2.5-mg frovatriptan is effective and well tolerated in Korean migraineurs for acute treatment of migraine attacks.

Pure trigeminal motor neuropathy is characterized by trigeminal motor weakness without signs of trigeminal sensory or other cranial nerve involvement. We describe a 63-year-old woman with progressive weakness and atrophy of the left masticatory muscles. She had no sensory disturbance. The diagnosis of pure trigeminal motor neuropathy was made on the basis of clinical and electrophysiologic studies. Magnetic resonance imaging of the brain revealed enhancement of the enlarged mandibular branch of the trigeminal nerve coursing through the left foramen ovale. Our observations suggest that pure trigeminal motor neuropathy can be induced by a tumor.

BACKGROUND: Blepharospasm and apraxia of lid opening (ALO) are nonparalytic causes of involuntary eyelid closure (IEC). Recently Aramideh (1994) divided the IEC into 5 groups by electromyography (EMG) study, and reported that each group had different responses to Botulinum A toxin treatment. Objective : We looked whether clinical observation can match the EMG, and possibly predict the response to Botulinum A toxiu treatment. Method : Based on EMG study of Aramideh (1994), clinically observable characteristics of each group were defined. One of the authors reviewed the videotapes of IEC and applied the above criteria to make the clinical diagnosis. Other author blinded to the clinical information performed 2 channel EMG of levator palpebrae superioris (LP) and orbicularis oculi (00) muscles, and made the EMG diagnosis. Clinical and EMG diagnoses were matched. Results : Twenty five patients (5 men and 20 women) were included in the study. Clinically, 16 were diagnosed as group I (blepharospasm), 1 as group 111(combined blepharospasm and LP motor impersistence), 7 as group tV(combined blepharospasm and involuntary LP inhibition), and 1 as group V(involuntary LP inhibition). There were no patient in group ll (combined dystonic activities of LP and 00). On EMG study, 14 were diagnosed as group 1, 2 as group ll, 1 as group 111, 7 as group IV, and 1 as group V The mismatch between the two diagnoseis occurred between group I and tV in 4 patients, group I and ll in 2, and group I and 111 in 2. Conclusions : Clinical observations are generally correct in predicting EMG diagnosis. Holvever groups with mixed features(ll, 111, and Iv) are difficult to diagnose by clinical observation only. Usefulness of clinical and EMG diagnosis on predicting Botulinum A toxin response will need to be evaluated. Key Words : Involuntary eyelid closure, Blepharospasm, Apraxia of lid opening, Electromyography.

BACKGROUND AND PURPOSE: Frequently the conventional nerve conduction studies (NCS) with testing usual peripheral nerves did not reveal any abnormalities in patients with early polyneuropathy. Recently Lee and Oh demonstrated that the interdigital sensory nerve conduction studies (NCS) of the foot were very sensitive in detecting early changes of neuropathy. The authors performed the study to see abnormal features of interdigital NCS in early phase of polyneuropathy and to understand the sensitivity of interdigital NCS in making diagnosis of polyneuropathy. METHODS AND MATERIALS: The interdigital NCS of the foot were performed in 19 clinically suspected polyneuropathy with no abnormalities by the conventional NCS (group I), in 7 polyneuropathy with electrophysiological abnormalities by the conventional NCS (group II), and 10 normal controls without clinical or electrophysiological findings of polyneuropathy (group III). The interdigital NCS were done according to the original description of Oh et al ,using the near-nerve needle recording at the level of ankle with averaging technique. The maximal nerve conduction velocity (NCV), the largest negative NCV, the amplitude and the duration of compound nerve action potential (CNAP) were analysed in each recording of I,V digital and I-II, II-III, III-IV, IV-V interdigital nerves of the foot. RESULTS: The abnormal interdigital NCS findings were found in 9 out of 19 patients in group I (47.4% ) , 7 out of 7 patients in group II(100.0%) ,and none in group III.(0.0%). In group I, the most common abnormal findings were no recordable CNAP (77,7%) and the second were the decreased amplitude of CNAP (66.6%). The decreased NCV were found only in one case ( group I-19). The digital or interdigital nerves involvement were symmetrical and the number of involved branches ranged from one to twelve, being averaged to be 7. In group II, the most common abnormalities were no recordable or decreased amplitude of CNAP (85.7 %) and the decreased NCV were found in 1 out of 7. Three out of 7 showed abnormalities in all digital or interdigital nerves and the remaining four showed abnormal findings in at least 4 among 12 digital or interdigital nerves. CONCLUSION: The interdigital NCS with the near nerve needle and averaging technique increased the diagnostic sensitivity in those subjects with clinically suspected polyneuropathy (group I) and the most common abnormal features in the interdigital NCS were the amplitude changes of CNAP. Therefore the authors suggest that the interdigital nerves of the foot are involved earlier in the process of polyneuropathy and the interdigital NCS of the foot might provide enhanced sensitivity for detecting early polyneuropathy.

Parkinsonism is a clinical syndrome with constellation of resting tremor, rigidity, bradykinesia, and a variety of gait disturbances. Gait disturbances in parkinsonism include short-stepped festination, loss of postural reflexes, and freezing. In certain parkinsonian states such as progressive supranuclear palsy, gait disturbances are very prominent over other clinical signs of parkinsonism in the early stage. However, freezing is usually seen in the late course of parkinsonism. Recently, it has been recognized that some patients have prominent freezing in their early course of the disease, and not much of other parkinsonian signs. The pathologies need to be confirmed, but must be divers based on clinical description of the cases. We report two elderly men who presented with pure freezing. There was minimal short-term memory impairment in the second case, but no other signs of parkinsonism were present. Brief trial of L-dopa did not offer much benefit. Detailed clinical features and laboratory findings will be presented with discussion of the literatures.

BACKGROUND: With the aid of high-resolution MRI, the identification of neuronal migration disorder(NMDs) is increasing and NMDs are considered as one of the major causes of extrahippocampal epilepsy. However, MRI has some limitatons in detecting small cortical lesion of NMDs. We have studied the diagnostic value and findings of brain SPECT and PET in the patients with NMDs. METHODS: Nineteen NMD patient with intrac table and partial epilepsy were studied. Diagnosis of NMDs was based on neuroimaging and pathology. Proton, Tl and T2-weighted axial, saggital and coronal MR image were obtained by 1.5 Tesla unit. Interictal and ictal SPFCT and PET imagings were performed with 99mTc-HMPAO and 18F-fluorodeoxyglucose. RESULT: Focal cortical dysplasia (FCD) and schizencephaly were detected in 4 patients, heterotopias in 3(one with 3 isolated lesions and one with bilateral temporal lobe lesions), polymicrogyria in 3, hemi-megalencephaly in 2, pachygyria in 2, forme fruste of tuberculous sclerosis(FFTS) in 1. Heterotopia was also combined with other lesions as schizencephaly, FFS and pachygyria. The MRI detected the lesions in 14 patients(73.7%). Of the 5 patients without definite abnormalities on MRI, 3 had focal polymicrogyda and 2 had FCD on pathologic examination. The interictal SPECT revealed abnormalities in 9 of 12 patients(75.0%), but could not detect 2 FCDs and one heterotopia. The ictal SPECT detected the lesions in all 11 patients. PET showed the compatible abnormalities in 17 patients(89.5%), but there was no abnormal finding in 2(1 with FCD and 1 with heterotopia). The abnormal lesions in PET were more extensive than those in MRI in the 8 patients with focal NMDs. Heterotopia showed cortical gray matter activity on PET in 6 out of 11 lesions. All other NMDs showed hypometabolism or metabolic detect in the interictal SPECT and PET. CONCLUSION: Functional imaging as SPECT & PET may be more selective than MRI to detect focal cortical lesions in NMD. NMDs show, variable metabolic pattern on functional imagings and in general the derangement in the functional imaging is more widespread than the lesions detected by MRI. We recommend the functional neuroimaging in the patients who are suspected to have partial seizure of neocortical origin and have no abnormal findings on brain MRI.
