Conversion disorder is a diagnosis based on a psychological construct that currently has no known neurobiologic substrate. But It is not easy to differentiate a real conversion disorder from a neurological disease or other medical disease. A patient in this case report had been diagnosed as conversion disorder but later it was found that the conversion disorder was misdiagnosis. During the 7 days of treatment, this patient was treated by herb medication, acupuncture and TENS and bad a little improvement. Both way, this patient was evaluated and evantually was diagnosed as Guillain-Barre Syndrome Miller-Fisber Variant, suggesting that the former diagnosis bad been a mistake. In this case report, we will present this patient's case and review the misdiagnosis of conversion disorder.

Epilepsy is a neurological disorder from many molecular and biochemical responses. In the underlying mechanism, free radicals play an important role in seizure initiation and seizure-induced brain damage. Excessive production of oxygen free radicals and other radical species have been implicated in the development of seizures under pathological conditions and linked to seizure-induced neurodegeneration.

Objectives: This study investigates lay beliefs about the etiology and treatments of tic disorder and Tourette's syndrome, as well as identifying sociodemographic and personality variables affecting these beliefs among South Koreans. Methods: In total, 673 participants (mean age $41.77{\pm}12.03$ years) completed an online survey regarding their beliefs about tic disorder and Tourette's syndrome. The factors related to their lay beliefs about the disorders were analyzed, and the correlates were investigated. Results: Results indicated that lay people in South Korea held strong beliefs that the causes of tic disorder and Tourette's syndrome lie within the parenting/psychological and neurological/biological categories, compared to the dietary/environmental one. Among the sociodemographic variables, sex, age, and levels of subjective mental health knowledge were primarily associated with the aforementioned beliefs. Familiarity with tic disorder and Tourette's syndrome was also associated with these beliefs. Among the personality traits investigated, extraversion and conscientiousness had significant influences on the beliefs people had about tic disorder and Tourette's syndrome. Conclusion: The results suggest that both policy makers and mental health service providers should adopt a strategic approach for developing and implementing health education interventions about tic disorder and Tourette's syndrome because individual sociodemographic variables, familiarity with the disorders, and personality traits are all associated with the beliefs about these disorders.

Adrenoleukodystrophy (ALD) is an X-linked disorder which has diverse constellation of clinical pictures, ranging from the severe childhood cerebral form to adrenocortical insufficiency without neurological manifestations. This disorder is caused by the mutations in the ABCD1 gene encoding the adrenoleukodystrophy protein (ALDP), a transporter in the peroxisome membrane. ALD in most cases is inherited from one parent. Here, we report an incidentally identified sporadic case with ALD after traffic accident. He had adrenocortical insufficiency as well as abnormal findings in brain image. Genetic testing of ABCD1 gene revealed a previously reported mutation. With the description of clinical features of ALD in this patient, we discussed the difficulty in determining an appropriate therapeutic option for ALD patients with minimal neurological manifestation.

Glutaric aciduria type 1 (GA1; OMIM #231670) is a rare autosomal recessive inherited neurometabolic disorder caused by the deficiency of glutaryl-CoA dehydrogenase. Infantile-onset GA1 is the most common form characterized by striatal injury and progressive movement disorder, and it is often triggered by an acute encephalopathic crisis within the first three years of life. Once this crisis occurs, there is a high likelihood for ineffective or limited conventional interventions, neurological disorders, or even death. Therefore, early diagnosis and immediate preventive management, such as dietary therapy, is essential. In the past decades, newborn screening (NBS) by tandem mass spectrometry for GA1 has been largely introduced in many countries including Korea, and it has led to improvements in the neurological outcomes of patients with GA1. In this review, the clinical symptoms, natural histories, and outcomes before and after the introduction of NBS in patients are discussed.

Objective : We investigated relationship between tinnitus and temporomandibular disorder(TMD) and tried to find approach possibility in oriental medicine. Method : We searched Pubmed, Scopus, The Cocharane library and additional sources for published and unpublished trials. Search word was "Tinnitus and TMD" Result : We investigated 18 studies. We divided these studies into three parts, epidemiological studies, mechanical studies and treatment studies. In many epidemiological studies. there was significant relationship between tinnitus and TMD. The mechanism was not clear but in recently several studies proposed neurological approach. TMD treatment showed significant improvement in tinnitus accompanied by TMD. Conclusion : In tinnitus accompanied by TMD, TMD treatment can be available to resolve or reduce tinnitus. Especially in oriental medicine acupuncture can be applied to treat this.

Purpose : Cerebrovascular disease is the most frequent cause of death in Korea and it remains severe disabilities disturbing normal life, According to the previous studies, mortality of the stroke in the first one week is up to the 20% and 95% of stroke patients in the acute stage are accompanied by more than one complications. These complications affect not only the acute stage mortality but also the late stage rehabilitations. In Korea the oriental medicine is preformed in the treatment of stroke. Therefore it is important to recognize thoroughly the complications in the acute stage of stroke and to prevent them. But studies about complications of acute stage stroke is rarely presented in the fields of oriental medicine. So this study is prepared for investigating the characteristics and frequency of complications in the acute stage of stroke. And we are to assess the importance of theses acute complications by systemic reviewing the previous studies. Methods : Fifty one patients are included who had been admitted to ICU(intensive care unit) of Chenju Hospital of Wonkwang Oriental Medicine. Twenty nine patients are diagnosed as ischemic stroke and twenty one patients are diagnosed hemorrhagic stroke. Medical and neurological complications were investigated retrospectively based on medical notes excluding primary symptoms of stroke Le. motor weakness, sensory disturbance and speech disorder. And risk factors of stroke such as D.M. or hypertension are excluded. Results : Medical complications are more frequent than neurological ones. Most frequent medical complication is dysuria(61%) and constipation(45%), fever(30%) and aspiration pneumonia(22%) are followed in order of frequency. In Neurological complication dysphagia(56%), the exacerbation of infarction due to increased intracranial pressure(24%), irritability or insomnia(21%) is most frequently complicated in order of frequency. Conclusions : These complications are mostly caused by bed rest state in acute stage stroke. It is supposed that more aggressive management can prevent theses ones. And it is possible to improve the medical and neurological conditions by sticking theses study results.

Griscelli syndrome type 2 (GS2) is a rare autosomal recessive disease caused by mutations in the RAB27A gene. It is characterized by cutaneous hypopigmentation, immunodeficiency, and hemophagocytic lymphohistiocytosis. We describe 2 brothers who had GS2 with clinically diverse manifestations. The elder brother presented with a purely neurological picture, whereas the younger one presented with fever, pancytopenia, hepatosplenomegaly, and erythema nodosum. Considering that cutaneous hypopigmentation was a common feature between the brothers, genetic analysis for Griscelli syndrome was performed. As the elder sibling had died, mutation analysis was only performed on the younger sibling, which revealed a novel homozygous mutation in the RAB27A gene on chromosome 15 showing a single-base substitution (c.136T>A p.F46I). Both parents were heterozygous for the same mutation. This confirmed the diagnosis of GS2 in the accelerated phase in both siblings. The atypical features of GS2 in these cases are a novel mutation, isolated neurological involvement in one sibling, association with erythema nodosum, and 2 distinct clinical presentations in siblings with the same genetic mutation.

Electroencephalography (EEG) produces time-series data of neural oscillations in the brain, and is one of the most commonly used methods for investigating both normal brain functions and brain disorders. Quantitative EEG analysis enables identification of frequencies and brain activity that are activated or impaired. With studies on the structural and functional networks of the brain, the concept of the brain as a complex network has been fundamental to understand normal brain functions and the pathophysiology of various neurological disorders. Functional connectivity is a measure of neural synchrony in the brain network that refers to the statistical interdependency between neural oscillations over time. In this review, we first discuss the basic methods of EEG analysis, including preprocessing, spectral analysis, and functional-connectivity and graph-theory measures. We then review previous EEG studies of brain network characterization in several neurological disorders, including epilepsy, Alzheimer's disease, dementia with Lewy bodies, and idiopathic rapid eye movement sleep behavior disorder. Identifying the EEG-based network characteristics might improve the understanding of disease processes and aid the development of novel therapeutic approaches for various neurological disorders.
