  • The purpose of this study was to evaluate the effects of electrical stimulation on vestibular compensation following ULX in rats. Electrical stimulation (ES) with square pulse ($100{\sim}300uA$, 1.0 ms, 100 Hz) was applied to ampullary portion bilaterally for 6 and 24 hours in rats receiving ULX. After ES, animals that showed the recovery of vestibular symptoms by counting and comparing the number of spontaneous nystagmus were selected for recording resting activity of type I, II neurons in the medial vestibular nuclei (MVN) of the lesioned side. And then the dynamic neuronal activities were recorded during sinusoidal rotation at a frequency of 0.1 Hz and 0.2 Hz. The number of spontaneous nystagmus was significantly different 24 hours (p<0.01, n=10), but not 6 hours after ULX+ES. As reported by others, the great reduction of resting activity only in the type I neurons ipsilateral to lesioned side was observed 6, 24 hours after ULX compared to that of intact labyrinthine animal. However, the significant elevation (p<0.01) of type I and reduction (p<0.01) of type II neuronal activity were seen 24 hours after ULX+ES. Interestingly, gain, expressed as maximum neuronal activity(spikes/sec)/maximum rotational velocity(deg/sec), was increased in type I cells and decreased in type II cells 24 hours after ULX+ES in response to sinusoidal rotation at frequencies of both 0.1 Hz and 0.2 Hz. This result suggests that accompanying the behavioral recovery, the electrical stimulation after ULX has beneficial effects on vestibular compensation, especially static symptoms (spontaneous nystagmus), by enhancing resting activity of type I neurons and reducing that of type II neurons.

  • Electroconvulsive therapy (ECT) is indicated for various mental disorders (e.g., major depressive disorder, schizophrenia, and bipolar disorder) and the behavioral and psychological symptoms of dementia in elderly patients. Furthermore, ECT is a useful first-line treatment in emergency and crisis situations such as suicide risk, violent behavior, catatonia, and food refusal, which are more frequent in elderly patients. ECT is also effective in the treatment of the motor symptoms of neurological disorders, such as Parkinson's disease and Huntington's disease. Due to the high risk of various physical diseases, the comorbid physical conditions of elderly patients should be individually controlled to optimize ECT treatment. Compared to young adults, in elderly patients the seizure threshold is higher, the seizure duration is shorter, and the anesthetic dose is lower. On the contrary, the response rate in the elderly is both faster and higher. Considering potential cognitive decline and the prevention of further deterioration of cognitive function in elderly patients, in the absence of significant comorbidities, twice weekly sessions and right unilateral electrode placement with a lower seizure threshold and less cognitive effect are preferred to bilateral electrode placement, which has a high risk of adverse cognitive effects. After an acute course of ECT, continuation and maintenance of ECT, combined with prescription of therapeutic drugs, may prevent possible relapse or recurrence of mental disorders. In conclusion, ECT can be used to treat mental disorders in elderly adults, with safety and effectiveness comparable to that in young adults.

  • Background: Cervical mobilization has been applied mainly for the improvement of arm and neck movements and pain reduction, and little research has been done to improve the executive function. Since this kind of so-called mechanical neck pain is one of most common symptoms, there are controversial issues about this with spine alignment. Posteroanterior (PA) mobilization from the Maitland concept is a process of examination, assessment, and treatment of neuromusculoskeletal disorder by manipulative physical therapy. Objective: To examine the short-term benefits of mobilization for patients with non-specific neck pain. Design: Dual-group Pretest-Posttest Design from the Quasi-Experimental research Methods: Fourteen participants (male 8, female 6; 20's of their age) with non-specific neck pains which are distributed all the unilateral or bilateral body side were recruited. Participants were categorized to Neck Pain with Movement Coordination Impairments (NPMCI) and Neck Pain with Mobility Deficits (NPMD) groups according to the results of physical examination. Professional physical therapist who has over 15-years-of clinical experience applicated manipulative therapy for the neck pain, an occupational therapist only conducted evaluations; K-NDI (Korean version of the Neck Disability Index), VAS (Visual Analog Scale), BDS-K (Korean version of Behavioral Dyscontrol Scale) for decreasing possible adverse effects; there were no person who reported other symptoms followed 4 weeks from the trial. Results: In the NPMCI group, data analysis indicated statistical differences between the PA mobilization interventions in NDI and BDS-K; even though, pain was reduced in VAS, this is not a significantly differ. In the NPMD group, data analysis represented statistical differences between the PA mobilization interventions in NDI, VAS and BDS-K; the scores were represented to be increased or the pain got relief. Conclusions: PA mobilization techniques according to Maitland concept have beneficial effects in patients with neck pain and other clinical positive effects which included neck disability, pain itself and motor function of upper extremity.

  • Objectives: To review and analyze clinical and preclinical evidence of effectiveness, safety, and underlying mechanisms of yokukansan (YKS), a herbal medicine, in alleviating aggression. Methods: Classical records on YKS were searched in the Korean Traditional Medicine Knowledge Database (KTMKD). By searching five electronic databases, prospective clinical studies and preclinical studies of YKS for alleviating aggression/agitation published up to March 30, 2021 were included. Results: Only two classical records on YKS were found from the KTMKD. A total of 11 clinical studies and 15 preclinical studies were found from the five electronic databases. Among 11 clinical studies, seven enrolled patients with dementia and four enrolled patients with other neuropsychiatric disorders. Most clinical studies reported significant improvement in one or more outcomes related to aggression in the YKS group after treatment. Among 15 preclinical studies, all studies except two reported a significant decrease in aggression/agitation-related behavior of YKS or yokukansankachimpihange. Suggested underlying mechanisms of YKS or yokukansankachimpihange for aggression/agitation in these studies included regulation of serotonin receptor, amelioration of abnormal glucocorticoid level related to the hypothalamic-pituitary-adrenal axis, regulation of orexin secretion, amelioration of degeneration in brain cells including glia cells, and suppression of excessive glutamatergic or dopaminergic activity. Conclusions: There were some clinical and preclinical evidence supporting the effectiveness and safety of YKS for alleviating aggression. Given that aggression is the most frequent and destructive symptoms of behavioral and psychological symptoms of dementia, applicability of YKS as a herbal medicine should be further investigated in future high-quality research.

  • Nonconvulsive Status Epilepticus(NCSE) refers to continuous epileptic condition with altered mental status and behavioral symptoms, but without convulsive movement at least 10 minutes. In Salzburg criteria, well known as the diagnostic criteria of NCSE, it is diagnosed with clinical symptoms, electroencephalogram (EEG), and effects before and after the use of antiepileptic drugs (AEDs). Commonly being used to treat NCSE, AEDs are likely to have adverse effects. In the present case, a 85-year-old female NCSE patient complaining delirium underwent combined Korean medical treatment by acupuncture and herbal medicine for 13 days. The effect of treatment was assessed with delirium scales including Delirium Rating Scale-Revised-98(DRS-R-98) and Assessment Test for Delirium & Cognitive Impairment(4AT) per 2 days. After the treatment, both DRS-R-98 and 4AT scores decreased, and orientation and mental status of patient improved. This case report suggests that Korean medical treatment might be an effective option without side for those NCSE patients complaining delirium.

  • The prevalence rate of plant poisoning is growing up gradually. However, it could be difficult to get proper treatment without detail medical history taking due to the diversity of poisonous plants and their various symptoms. Scopolia Japonica, which grows naturally in Korea, is reported to cause severe toxicity which could be lethal. A few therapeutic measures have been reported in Traditional Korean Medicine (TKM), but it has not been reported yet that those measures have been successfully proven in the clinical practice in modern times. This is a case report of toxicity caused by scopolia japonica ingestion. A 65years-old male patient with cognitive impairment, behavioral disorder, gait difficulty, dysarthria, dysphagia and abnormal pupil reflex recovered from those symptoms during taking Gamigamdu-tang and getting acupuncture. This study shows the clinical aspects of Scopolia Japonica toxicity and the possibility of TKM treatments as one of plant poisoning treatments.

  • Background and Objectives: Menkes disease (MNK) is a rare X-linked recessive disease, caused by mutations in the copper transporting ATP7A gene that is required for copper homeostasis. MNK patients experience various clinical symptoms including neurological defects that are closely related to the prognosis of MNK patients. Neural stem cells (NSCs) in the hippocampal dentate gyrus (DG) produce new neurons throughout life, and defects in DG neurogenesis are often correlated with cognitive and behavioral problems. However, neurodevelopmental defects in the DG during postnatal period in MNK have not been understood yet. Methods and Results: Mottled-brindled (MoBr/y) mice (MNK mice) and littermate controls were used in this study. In vivo microCT imaging and immunohistochemistry results demonstrate that blood vasculatures in hippocampus are abnormally decreased in MNK mice. Furthermore, postnatal establishment of NSC population and their neurogenesis are severely compromised in the DG of MNK mice. In addition, in vitro analyses using hippocampal neurosphere culture followed by immunocytochemistry and immunoblotting suggest that neurogenesis from MNK NSCs is also significantly compromised, corresponding to defective neurogenic gene expression in MNK derived neurons. Conclusions: Our study is the first reports demonstrating that improper expansion of the postnatal NSC population followed by significant reduction of neurogenesis may contribute to neurodevelopmental symptoms in MNK. In conclusion, our results provide new insight into early neurodevelopmental defects in MNK and emphasize the needs for early diagnosis and new therapeutic strategies in the postnatal central nerve system damage of MNK patients.

  • 연구목적 본 연구는 주의력결핍 과잉행동장애(attention-deficit/hyperactivity disorder, ADHD) 환자들을 대상으로 다양한 실행기능과 정량화 뇌파간의 상관성을 알아보고자 하였다. 방법 31명의 소아청소년 ADHD 환자를 대상으로 정량화 뇌파를 측정하였다. 종합주의력검사(Comprehensive Attention Test, CAT), 스트룹 색-단어 추론 검사(Color-Word Inference Test, CWIT), 선추적 검사(Trail Making Test, TMT), 카드분류검사(Card Sorting Test, CST)가 시행되었고 한국어판 주의력결핍 과잉행동장애 평정척도(Korean version of the ADHD Rating Scale, K-ARS)가 측정되었다. 결과 CAT 검사 점수와 알파, 베타 파워가 양적 상관이 있는 반면, 델타 파워와는 부적 상관이 있었다. CWIT 검사에서는 감소된 델타 파워와 증가된 베타 파워가 높은 수행수준과 관련 있었다. 높은 TMT 검사 점수는 증가된 알파 대역 파워와 관련이 있었으며, CST 검사에서 델타 파워는 높은 수행수준과 부적 상관이 있는 반면 알파, 하이 감마파의 파워와는 양적 상관을 보였다. K-ARS 점수는 알파 파워와 부적 상관을 보였다. 결론 정량화 뇌파는 ADHD 환자들의 실행기능과 상관성을 보이며 신경생리학적 지표로서의 유용성이 시사된다.
