Objectives: To conduct and report the results of a public health promotion program in Korean medicine (KM), namely the KM Visiting Care Service for Solitary Elderly, from November 2018 to April 2019. Methods: Six elderly people living in a rural area received the KM visiting care service, twice a week, for four months. This service consisted of acupuncture, auriculotherapy, and supportive counseling to manage their musculoskeletal pain, cognitive impairment, and/or depression. The changes of symptoms were assessed using Numeric Rating Scale (NRS), Korean version of Mini-Mental State Examination for Dementia Screening (MMSE-DS), Korean version of Montreal Cognitive Assessment (MoCA-K), and Geriatric Depression Scale-Short form Korean (GDS-SF-K). Results: Through the 4-months KM visiting care service, the overall subjects' NRS-rated pain decreased slightly. Most showed improvement in MMSE-DS and/or MoCA-K, except one subject who was diagnosed with Alzheimer's disease. Depression assessed by GDS-SF-K showed improvement in a few subjects who were unable to walk independently. Satisfaction assessed through survey was generally high in all subjects. Conclusions: This KM Visiting Care Service for Solitary Elderly may help improve the pain and cognitive function of frail solitary elderly in rural areas. However, the protocol need to be improved to optimize the effect.

연구목적 갑상선관련 호르몬과 인지기능의 상관 유무는 논란이 되고 있다. 알츠하이머병과 경도인지장애 환자에서 갑상선관련 호르몬 농도에 차이가 있는지 비교해 보고, 나아가 갑상선관련 호르몬 농도가 인지기능의 어떠한 영역과 관련이 있는지에 대해 연구해보고자 하였다. 방 법 2011년 1월부터 2018년 12월까지 기억력 저하를 주소로 일산백병원 정신건강의학과 치매클리닉을 방문하여 알츠하이머병(NINCDS-ADRDA 진단기준)과 경도인지장애(Petersen 진단기준) 으로 진단된 105명의 환자를 대상으로 한 후향적 연구이다. 갑상선관련 호르몬[삼요오드티로닌(Triiodothyronine, T3), 티록신(Thyroxine, T4), 갑상선 자극 호르몬(Thyroid stimulating hormone, TSH)]의 측정은 화학발광면역측정법을 사용하여 검사하였다. 알츠하이머병군과 경도인지장애군 간의 갑상선관련 호르몬의 평균치 분석을 위하여 독립표본 t-검정을 시행하였다. 갑상선관련 호르몬이 전반적 퇴화 척도(Global deterioration scale, GDS), 치매임상평가척도(Clinical dementia rating, CDR) 및 한국형 임상치매평가척도(The Korean version of the consortium to establish a registry for Alzheimer's disease, CERAD-K)의 각 항목 별 점수들과 유의한 상관이 있는지 알아보기 위하여 한국판 노인우울척도(Geriatric depression scale-Korean version, GDS-K)를 통제변수로하여 편상관분석을 시행하였다. 결 과 총 105명의 환자 중 알츠하이머병군은 74명, 경도인지장애군은 31명이었다. 알츠하이머병군과 경도인지장애군 간 혈청 T3, T4, TSH 농도의 평균은 모두 유의한 차이가 없었으나, CERAD-K 항목 중 구성행동 검사(Construction praxis test, CPT)가 혈청 TSH 농도와 유의한 양의 상관 관계를 보였다(p-value=0.004). 결 론 본 연구에서 실행기능과 연관된 CPT가 혈청 TSH 농도와 유의한 양의 상관 관계를 보인 것은 갑상선관련 호르몬과 치매의 병태생리와의 연관성에 대한 이해에 도움을 줄 수 있다고 생각한다. 향후 갑상선관련 호르몬이 인지기능에 미치는 병태생리 기전에 관한 전향적 연구들이 필요할 것으로 사료된다.

The purpose of the present study was to validate the use of tissue radioactivity ratios instead of regional metabolic rates for the assessment of regional metabolic changes in Alzheimer's disease(AD) with [$^{18}F$]FDG PET and to examine the correlation of ratio indices with the severity of cognitive impairment in AD. Thirty-seven AD Patients(age $68{\pm}9 yrs$, $mean{\pm}s.d.$; 36 probable and 1 definite AD), 28 patients with dementia of non-Alzheimer type(age $66{\pm}7 yrs$), and 17 healthy controls(age $66{\pm}4 yrs$) underwent [$^{18}F$]FDG PET imaging. Two simplified radioactivity ratio indices were calculated from 37-66 min image: region-to-cerebellar radioactivity ratio(RCR) and a composite radioactivity ratio(a ratio of radioactivity in the most typically affected regions over the least typically affected regions: CRR). Local cerebral metabolic rate for glucose(LCMRglu) was also measured using a three-compartment, five-parameter tracer kinetic model. The ratio indices were significantly lower in AD patients than in controls(RCR in temporoparietal cortex, $0.949{\pm}0.136$ vs. $1.238{\pm}0.129$, p=0.0004; RCR in frontal cortex, $1.027{\pm}0.128$ vs. $1.361{\pm}0.151$, p<0.0001; CRR, $0.886{\pm}0.096$ vs. $1.032{\pm}0.042$. p=0.0024). On the RCR analysis, 86% of AD patients showed a pattern of bilateral temporoparietal hypometabolism with or without frontal involvement; hypometabolism was unilateral in 11% of the patients. When bilateral temporoparietal hypometabolism was considered to be suggestive of AD, the sensitivity and specificity of the RCR analysis for the differential diagnosis of AD were 86% and 73%, respectively. The RCR was correlated significantly with the macroparameter K [$K_1k_3/(k_2+k_3)$] (r=0.775, p<0.0001) and LCMRglu(r=0.633, p=0.0002) measured using the kinetic model. In patients with AD, both average RCR of cortical association areas and CRR were correlated with Mini-Mental Status Examination(r=0.565, p=0.0145; r=0.642, p=0.0031, respectively), Clinical Dementia Rating(r=-0.576, p=0.0124; r=-0.591, p=0.0077), and total score of Mattis Dementia Rating Scale (r=0.574, p=0.0648; r=0.737, p=0.0096). There were also significant correlations between memory and language impairments and corresponding regional RCRs. The results suggest that the [$^{18}F$]FDG PET ratio indices, RCR and CRR, reflect global and regional metabolic rates and correlate with the severity of cognitive impairment in AD. The simplified ratio analysis may be clinically useful for the differential diagnosis and serial monitoring of the disease.

Objective : This study explored the relationships among demographic (DVs) and clinical variables (CVs), neurocognitive (NOs) and functional outcome (FO) that could be used as prognostic factors for old aged patients with traumatic brain injury (TBI) undergoing or appointed disability evaluation (DE) after treatment. Methods : A total of 162 subjects with TBI above the age of 55 years undergoing DE or appointed to do so after treatments were selected. The patients were divided into two subgroups according to age : a junior elderly group 55 to 64 years old and a senior elderly group over the age of 65. NOs and FO were evaluated using the Seoul Neuropsychological Screening Battery and Clinical Dementia Rating scale. Results : Gender, age, and education level were shown to significantly impact the recovery of NOs after TBI. Other DVs and CVs such as area of residency, occupation, type of injury, or loss of consciousness were not found to significantly affect the recovery of NOs after TBI. Analysis of the relationships among DVs, CVs and NOs demonstrated that gender, age, and education level contributed to the variance of NOs. In FO, loss of consciousness (LOC) was included to prognostic factor. Conclusion : Gender, age and education level significantly influence the NOs of elderly patients with TBI. LOC may also serve as a meaningful prognostic factor in FO. Unlike younger adult patients with TBI, old aged patients with TBI did not show global faking-bad or malingering attitudes to DE for compensation, but assume that they could faking their performance in a test set available visual feedback.

Parkinson's disease is one of the typical neurodegenerative disease and it is caused by the destruction of substantia nigra in brain leading to lack of dopamine secretion, and it presents 4 major motor symptoms such as tremor, bradykinesia, stiffness, postural instability. Furthermore, it causes many non-motor symptoms such as anosmia, REM sleep conduct disorder, orthostatic hypotension, dementia and autonomic ataxia such as lack of adjusting blood pressure, hyperhydrosis, constipation. Dopaminergic therapy is the most commonly used strategy, but long term treatment of levodopa induce various adverse effects. Thus, many people are focusing on new therapies other than established therapies, and there are many tries and approaches with paradigm shift. Our medical team was able to get 4 cases of PD patients who are hospitalized in our hospital, treated by Whole Body Gi-Hyeol Therapy consisting of acupuncture therapy, herbal therapy, and mental therapy, and their conditions improved in perspective of Unified Parkinson's Disease Rating Scale(UPDRS), Heart Rate Variability(HRV), and Quality of life. Among all 4 cases, UPDRS score and quality of life score is gotton better, and among 2 cases SDNN, RMS-SD, TP, LF, HF scores are finely increased. And PDQ-39 score which shows quality of life is also improved. However, in spite of these improvements and positive results, there were no meaningful improvement in a hurt from a fall which is important to the aged, muscular atrophy which causes bone fracture and SMI(Skeletal Muscle Mass Index) which is indicator of osteoporosis. Thus, supplementary treatment about Whole Body Gi-Hyeol Therapy such as more active nutrition intervention, safe and effective kinesitherapy is needed, and from now on continuous case reports and systematic clinical research which has control group must be carried out.

연구목적 본 연구는 알츠하이머병(Alzheimer's disease, AD), 경도인지장애(Mild Cognitive Impairment, MCI), 정상군에서 체질량지수(Body Mass Index, BMI)의 차이를 분석하여 낮은 BMI 수치와 인지기능 저하와의 연관을 확인하고자 하였다. 또한, 한국판 간이정신상태검사(Mini Mental State Examination-Korean version, MMSEK), 치매임상평가척도(Clinical Dementia Rating, CDR), 전반적 퇴화척도(Global Deterioration Scale, GDS)과 BMI 사이에 연관성이 있는지도 알아보고자 하였다. 방 법 총 257명의 연구대상자들이 이 연구에 포함되었고, AD 및 MCI 진단을 위해 병력 청취, 정신상태검사, 신경인지기능검사, 신체 검사가 시행되었다. 대상자의 성별 및 연령과 신체 질환도 함께 조사하였다. 전반적인 인지기능과 질병의 심각도 단계 평가는 MMSE-K, GDS, CDR으로 측정하였다. 결 과 MMSE-K 점수는 정상군>MCI>AD 순이었으며 통계적으로 유의한 차이를 나타내었다(p=0.000). CDR과 GDS점수는 정상군이 가장 높았고, AD군이 가장 낮았으며 역시 통계적으로 유의한 차이를 나타내었다 BMI와 MMSE 점수 사이에는 유의한 양의 상관관계가 있었다(r=0.238, p=0.000). BMI와 CDR과는 음의 상관관계를 나타내었으며(r=-0.174, p=0.008), BMI와 GDS 역시, 음의 상관관계를 보였다(r=-0.233, p=0.000). 결 론 BMI와 인지기능과의 연관성이 있으므로, 치매나 경도인지장애 환자를 대상으로 BMI를 측정하는 것은 임상적 표지자로서 의미가 있을 것으로 예상된다. 본 연구는 AD의 진단 및 예방, 그리고 치료적 접근에 도움을 줄 수 있을 것으로 기대하며, 향후 이에 대한 대규모의 장기 추적 연구가 필요할 것으로 생각된다.

연구목적 본 연구에서는 섬망의 오진과 관련된 임상적 특징 및 임상의를 오진으로 유도할 수 있는 증상적 특징들을 알아보고자 한다. 방 법 일 대학병원에 입원하여 정신과에 협의진료 의뢰된 환자 중, 정신건강의학과 전문의에 의해 섬망으로 진단된 256명을 대상으로 후향적으로 의무기록을 조사하였다. 협진요청서에 명시된 사유를 검토하여, 의뢰의사의 진단이 섬망인 경우 진단일치군으로 섬망이 아닌 경우 진단불일치군으로 구분하였다. 결 과 69명(27%)이 진단불일치군으로, 섬망이 아닌 다른 진단으로 협진이 의뢰되었다. 진단불일치군에서 항정신병약물의 사용, 기질성 정신질환의 과거력이 많았다. Delirium rating scale-Revised-98(DRS-R-98) 중 증상의 변동 항목의 점수가 진단일치군에서 더 높았다. 로지스틱 회귀분석결과 질환의 낮은 심각도, 항정신병약물 사용력, 적은 증상의 변동이 임상의가 섬망 외에 다른 진단을 고려하는 예측인자였다. 결 론 본 연구에서 항정신병약물을 복용중인 경우, 섬망증상의 변동이 적은 경우 오진의 위험이 높았다. 지연된 섬망의 진단과 치료는 환자의 예후에 부정적인 영향을 미칠 수 있으므로 주의 깊은 임상적 관심이 필요하다.

Objectives: This study aimed to comprehend the characteristics of Korean medicine patterns in relation to varying degrees of cognitive impairment in an elderly population. Methods: The dataset included 127 elderly individuals with cognitive impairment obtained from three Korean medicine hospitals between 2018 and 2021. The participants were categorized into two groups based on Clinical Dementia Rating-Sum of Boxes (CDR-SB) scores: those with questionable impairment (QI) and those with very mild dementia (VMD). A diagnostic framework for Korean medicine patterns encompassing Qi deficiency, Yin deficiency, Phlegm dampness, and Heat-fire was employed. Liver blood markers, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the AST/ALT ratio, were also analyzed. Results: The scores of the cognitive assessment tools (MoCA-K, MMSE-DS, and K-IADL) of the QI group significantly differed from those of the VMD group. CDR-SB exhibited a positive correlation with the scores of each pattern of Qi deficiency, Yin deficiency, Phlegm dampness, and Heat-fire, whereas ALT and AST values displayed negative correlations. Binomial logistic analysis, controlling for potential confounders, such as age, education years, body mass index, the presence of chronic disease, and the presence of medication, verified that the VMD group showed higher pattern scores and lower ALT and AST values than the QI group. Conclusions: Increases in pattern scores along with decreased AST and ALT levels might be indicative of more severe cognitive impairment.

Objective : Postoperative delirium is a common complication in the elderly after surgery but few papers have reported after spinal surgery. We analyzed various risk factors for postoperative delirium after spine surgery. Methods : Between May 2012 and September 2013, 70 patients over 60 years of age were examined. The patients were divided into two groups : Group A with delirium and Group B without delirium. Cognitive function was examined with the Mini-Mental State Examination-Korea (MMSE-K), Clinical Dementia Rating (CDR) and Global Deterioration Scale (GDS). Information was also obtained on the patients' education level, underlying diseases, duration of hospital stay and laboratory findings. Intraoperative assessment included Bispectral index (BIS), type of surgery or anesthesia, blood pressure, fluid balance, estimated blood loss and duration of surgery. Results : Postoperative delirium developed in 17 patients. The preoperative scores for the MMSE, CDR, and GDS in Group A were $19.1{\pm}5.4$, $0.9{\pm}0.6$, and $3.3{\pm}1.1$. These were significantly lower than those of Group B ($25.6{\pm}3.4$, $0.5{\pm}0.2$, and $2.1{\pm}0.7$) (p<0.05). BIS was lower in Group A ($30.2{\pm}6.8$ compared to $35.4{\pm}5.6$ in group B) (p<0.05). The number of BIS <40 were $5.1{\pm}3.1$ times in Group A, $2.5{\pm}2.2$ times in Group B (p<0.01). In addition, longer operation time and longer hospital stay were risk factors. Conclusion : Precise analysis of risk factors for postoperative delirium seems to be more important in spinal surgery because the surgery is not usually expected to have an effect on brain function. Although no risk factors specific to spinal surgery were identified, the BIS may represent a valuable new intraoperative predictor of the risk of delirium.
