연구목적 본 연구의 목적은 알츠하이머병 및 경도인지장애 환자에서 백질고강도신호 차이에 따른 신경인지 기능 및 행동심리증상(BPSD)을 비교하는 것이다. 방 법 본 연구는 후향적 연구로서, 알츠하이머병 및 경도인지장애로 진단받은 115명을 대상으로 하였다. 뇌 자기공명영상의 백질 고강도 신호(white matter hyperintensity, WMH)는 표준화된 시각 기반 척도(Fazekas scales)에 의해 평가되었으며, 참가자들은 Fazekas 척도에 따라 두 그룹으로 분류되었다. 신경인지기능은 임상치매평가척도(CERAD-K)에 의해, BPSD는 한국형 신경정신행동검사(K-NPI)로 평가되었다. WMH의 심각도에 따른 신경인지기능 및 BPSD의 차이를 분석하기 위해 독립표본 t-test를 시행하였다. 결 과 WMH의 중증도가 높은 군은 유의하게 낮은 언어 유창성을 나타내었다(p<0.05). 또한 WMH의 중증도가 높은 군은 유의하게 높은 K-NPI 점수를 보였다(p<0.01). 결 론 WMH와 실행기능과 관련된 신경인지검사 간에는 유의한 연관이 있었다. 또한 WMH는 BPSD의 중증도에 영향을 미치는 것으로 보인다. 임상실제에서 WMH를 알츠하이머 병(Alzheimer's disease, AD)및 경도인지장애(Mild cognitive impairment, MCI)환자를 치료하는데 유용한 정보를 제공할 것이다.

In recent, growing aged people in coupled with the increased senile dementia, Alzheimer's disease, has been a social interests to be cleared out. Alzheimer Disease(AD), first reported by Alios Alzheimer (1864-1915) in 1907, is a neurodegenrative disease. Nothing exact cause of AD is available by now, but in clinical founding ${\beta}$-amyloid peptide(A${\beta}$) and microtubule associated protein($\tau$ protein) is to involved in the disease, and the most important feature in AD is Known to induce chronic inflammation to neuron cell.

뇌소혈관질환은 뇌 자기공명영상에서 흔히 관찰되는 혈관성 변화로 뇌백질 고신호강도, 뇌미세출혈, 열공성 경색, 혈관주위공간 등을 포함한다. 이러한 혈관성 변화가 알츠하이머병(Alzheimer's disease; 이하 AD)의 발병 및 진행과 관련되어 있고, 대표 병리인 베타 아밀로이드 및 타우 단백의 침착과도 연관되어 있다는 증거들이 축적되고 있다. 혈관성 변화는 생활습관 개선이나 약물 치료를 통해 예방과 개선이 가능하기 때문에 뇌소혈관질환과 AD 및 AD 생체지표의 관련성을 연구하는 것이 중요하다. 본 종설에서는 AD와 AD 생체지표에 대해 간략히 소개하고, AD와 혈관성 변화의 관련성에 대해 축적된 증거들을 제시한 다음, 뇌소혈관질환의 병태 생리와 MR 영상 소견을 설명하고자 한다. 또 뇌소혈관질환과 AD 진단의 위험도 및 AD 생체지표와의 관련성에 대한 기존 연구 결과들을 정리하고자 한다.

The purpose of this article was to investigate the current state of studies on clinical trials of acupuncture treatment for Alzheimer's disease using neuroimaging method. We searched for clinical trials of acupuncture treatment for Alzheimer's disease(AD) and mild cognitive impairment(MCI) using neuroimaging method in the MEDLINE (Pubmed) database on March 18, 2020. Once the online search was finished, studies were selected manually by the inclusion criteria. Finally, we analyzed the characteristics of selected articles and reviewed the neural substrates of acupuncture treatment in AD. Total ten studies were included in this study. The most frequently applied modality for AD was functional MRI. The most frequently selected acupoints for AD were KI3, LR3 and LI4. One of studies showed that acupuncture treatment could improve the symptoms of MCI. Through the analysis, we demonstrated that neuroimaging method could capture the neural substrates associated with AD. Moreover, acupuncture may induce differential response according to the disease status. Finally, real acupuncture could produce more extensive activation/deactivation than sham acupuncture. We hope that neuroimaging method can contribute to the clinical research of acupuncture treatment for AD through large-scale RCT and diverse imaging modality.

The diagnosis has an very important role in curing dementia. But there was not the effective method to diagnose it until now. In this paper we analyzed the EEG in Alzheimer's disease and normal control groups to differentiated them by nonlinear parameter such as the correlation dimension. And we propose the nonlinear analysis of EEG in Alzheimer's disease as a useful tool of early diagnosis of it.

Healthcare providers in Korea are using conservative pharmacological treatment for Alzheimer's disease (AD) to delay the progress of the disease or to mitigate its behavioral and neurological symptoms. However, there is a growing need for interventions using practical non-pharmacologic treatment, as the effects of pharmacological treatments has faced limitations. This research provided a cognitive rehabilitation program to 3 AD patients and used a multiple baseline design across subjects to examine the effects. Performing reality orientation therapy (ROT) for 1 cycle (4 weeks) resulted in a slight increase in accuracy and responsiveness on an orientation task, mainly with patients with mild cases of AD. Also, in the sub-domain of the Korean-Mini Mental Status Examination performed to examine changes in cognitive ability, there were minimal changes in place orientation. In functional communication, however, there were no significant differences before and after the intervention. In conclusion, we found that ROT was an effective intervention for improving accuracy and responsiveness in the orientation of patients with mild cases of AD. In future studies, the effect of non-pharmacological interventions can be evaluated more reliably by examining the interaction effects of sample size, length of the intervention, outcome measurements, and pharmacological intervention.

Alzheimer's disease(AD) is a progressive neurodegenerative disease, which is pathologically characterized by neuritic plaques and neurofibrillary tangles associated with the acetylcholinesterase, apolipoprotein E and butylcholinesterase, and by mutations in the presenilin genes PS1 and PS2, and amyloid precursor proteins (APPs) overexpression. The present research is to examine the inhibitory effect of KGBH on PS1, PS2 and APPs overexpression detected by Western blotting. To verify the Effects of KGBH on cognitive deficits further, we tested it on the scopolamine(1mg/kg)-induced amnesia model of the mice using the Morris water maze tests, and there were ameliorative effects on memory impairment as a protection against scopolamine. KGBH only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, where as blood glucose level was shown to attenuate the amnesia induced by scopolamine and inreased extracellular serum level. In conclusion, studies of KGBH that has been known as anti-choline and inhibitory ablilities of APPs overexpression, could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer's disease.

The present research is to examine the inhibition effect of MDOF on PS-1, PS-2 and APP overexpression by detected to Western blotting. To verify the effects of MDOF on cognitive deficits further, we tested it on the scopolamine-induced amnesia model of the mice using the Morris water maze tests, and there was ameliorative effects of memory impairment as a protection to scopolamine. MDOF only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, whereas blood glucose level was shown to attenuate the amnesia induced by scopolamine and inreased extracelluar serum level compared with only scopolamine injection. In conclusion, studies of MDOF that has been know as anti-choline and inhibition ablilities of APP overexpression, this could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer's disease.
