ABSTRACT

Background@#and Purpose There is no specific indicator for monitoring dementia management. We propose an auxiliary indicator called the community management rate, defined as the proportion of dementia patients who receive informal care from close caregivers or themselves within their community population. The 5-year community management rate is the percentage of dementia patients who are receiving community management at 5 years after they were diagnosed. The aim of this study was to identify how the community management rate has changed over time and how the 5-year community management rate differs according to age, sex, income, residence area, and comorbidities. @*Methods@#We analyzed customized research database of the Korean National Health Insurance Services from 2003 to 2018. The 5-year community management rate was calculated annually with newly diagnosed dementia patients, and compared among subgroups according to age, sex, income, residence area, and comorbidities. @*Results@#This study analyzed 549,297 patients. Among those newly diagnosed with dementia in 2003, the mean duration of community management during the 15-year follow-up was 5.98 years. The community management rate decreased rapidly from 2003 to 2006, after which it increased. A low 5-year community management rate was associated with older age, higher comorbidity burden, nonmetropolitan residence, and low income. @*Conclusions@#The community management rate seems to reflect diverse patient factors. Efforts are needed to reduce the comorbidity burden and differences in the 5-year community management rate according to residence area and income. This study indicates the need for further investigations into the use of this indicator to monitor the management of dementia patients.

ABSTRACT

Cytotoxic lesions of the corpus callosum (CLOCC) are secondary lesions on corpus callosum caused by cytokinopathy of callosal neurons and microglia. Fever, headache, and digestive disturbances are common symptoms. Reversible and hyperintense signals on fluid‐attenuated inversion recovery imaging, diffusion‐weighted imaging (DWI) and decreased apparent diffusion coefficient are typical features of magnetic resonance imaging. Herein, we report a rare case of CLOCC caused by COVID19 vaccination (BNT162b) and discharged without no neurologic symptoms due to prompt treatment.

ABSTRACT

Background@#To evaluate workload in emergency rooms (ERs) among clinical specialties including neurology and investigate characteristics of neurological consultations in ER. @*Methods@#A nationwide survey was conducted to evaluate the number of specialists, resident physicians/surgeons, and emergency consultations of each clinical specialty in Korean tertiary referral hospitals from 2018 to 2019. Characteristics of neurological emergency consultations during the same period were investigated in one of the hospitals that participated. @*Results@#A total of 23 hospitals were included. Four irrelevant clinical specialties were excluded. The number of neurology specialists and resident physicians were 12.5/hospital (4.1% of all specialists) and 6.4/hospital (3.4% of all resident physicians/surgeons), respectively, while the mean numbers of specialists and resident physicians or surgeons per clinical specialty were 13.7/hospital and 8.6/hospital, respectively. Neurological consultations accounted for 11.0% of all ER consultations for severe patients (Korean Triage and Acuity Scale level 1-3). Annual ER consultations for severe patients per neurology specialist was 274.1, which was only second to pediatrics (290.0). Annual ER consultations for severe patients per resident physician was 406.6 which was 1.6 times higher than the second highest (internal medicine, 247.0). Frequent conditions for neurological ER consultation were dizziness (24.8%), motor weakness (23.9%), headache (10.6%), dysarthria (9.9%), and seizures (7.7%). Frequent primary diagnoses were cerebrovascular diseases (29.0%) and episodic and paroxysmal disorders (24.9%). @*Conclusions@#Workloads of neurology specialists for ER consultation were significantly heavy, and the workload of neurology resident physicians was the heaviest among all specialties. This should be considered in health care policies.

ABSTRACT

Background@#Because Korea is the fastest aging country, the stroke incidence is increasing rapidly. We investigate the trend of the number of patients with acute stroke in recent years and estimate the burden of the neurologist to treat the acute stroke patient visited the emergency department. @*Methods@#We requested a questionnaire survey to all teaching hospitals on the number of hospital beds, the number of stroke patients who visited the emergency department, the number of stroke patients in charge of the neurologist, and the number of days on duty of residents from 2016 to 2019. @*Results@#Of 69 teaching hospitals, 41 hospitals answered the survey. The average hospital beds per hospital were increased annually from 909 to 916. The average patients who visited the emergency department with stroke and were in charged to neurologists were rapidly increased from 799 to 867 per hospital. In particular, the number of patients with hyperacute cerebral infarction requiring the thrombolytic administration or mechanical thrombectomy were rapidly increased from 105 to 131. On the other hand, the average number of residents per hospital was decreased from 5.1 to 4.8. Therefore, the days on duty per resident were increased from 74 to 77. @*Conclusions@#The number of acute stroke patients, especially, hyperacute stroke required the rapid cooperation and high labor were increasing rapidly in recent years. However, because the number of residents were decreased, the burden was increasing. To improve the quality of acute stroke treatment, it is necessary to increase the number of residents.

ABSTRACT

Background@#and Purpose Previous studies have revealed the diverse neuroprotective effects of GV1001. In this study, we investigated the effects of GV1001 on focal cerebral ischemia-reperfusion injury (IRI) in rats and oxygen-glucose deprivation/reoxygenation (OGD/R)-induced injury in neural stem cells (NSCs) and cortical neurons. @*Methods@#Focal cerebral IRI was induced by transient middle cerebral artery occlusion (MCAO). Brain diffusion-weighted imaging (DWI) was performed 2 hours after occlusion, and a total of 37 rats were treated by reperfusion with GV1001 or saline 2 hours after occlusion. Fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging, immunohistochemistry, and neurobehavioral function analyses were performed. Additionally, OGD/R-injured NSCs and cortical neurons were treated with different GV1001 concentrations. Cell viability, proliferation, migration, and oxidative stress were determined by diverse molecular analyses. @*Results@#In the stroke model, GV1001 protected neural cells against IRI. The most effective dose of GV1001 was 60 μM/kg. The infarct volume on FLAIR 48 hours after MCAO compared to lesion volume on DWI showed a significantly smaller ratio in the GV1001-treated group. GV1001-treated rats exhibited better behavioral functions than the saline-treated rats. Treatment with GV1001 increased the viability, proliferation, and migration of the OGD/R-injured NSCs. Free radicals were significantly restored by treatment with GV1001. These neuroprotective effects of GV1001 have also been demonstrated in OGD/R-injured cortical neurons. Conclusions The results suggest that GV1001 has neuroprotective effects against IRI in NSCs, cortical neurons, and the rat brain. These effects are mediated through the induction of cellular proliferation, mitochondrial stabilization, and anti-apoptotic, anti-aging, and antioxidant effects.

ABSTRACT

Background@#and Purpose Screening tests for dementia such as the Mini Mental State Examination (MMSE) and the Montreal Cognitive Assessment are widely used, but there are drawbacks to their efficient use. There remains a need for a brief and easy method of assessing the activities of daily living (ADL) that can be administered to elderly individuals by healthcare workers. We have therefore developed a new scale named the Simple Observation Checklist for Activities of Daily Living (SOC-ADL). @*Methods@#We developed the SOC-ADL scale as a team of experts engaged in caring for individuals with dementia. This scale comprises eight items and was designed based on the Korean instrumental activities of daily living (K-IADL) scale and the Barthel activities of daily living scale (Barthel Index). The new scale was validated by enrolling 176 patients with cognitive dysfunction across 6 centers. Confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were performed. We assessed its concurrent validity by performing comparisons with the Korean-MMSE, Clinical Dementia Rating, Clinical Dementia Rating-Sum of Boxes, K-IADL, and Barthel Index, and its criterion validity by performing comparisons between mild cognitive impairment (MCI) and dementia. We also used Cronbach’s alpha to assess the interitem reliability. The appropriate cutoff values were determined by analyzing receiver operating characteristic curves, including the areas underneath them. @*Results@#EFA extracted one factor and CFA revealed that all of the model fits exceeded the minimum acceptable criteria. The SOC-ADL scores were strongly correlated with those of the other tools for dementia and could be used to differentiate MCI from dementia. Cronbach’s alpha values indicated that the results were reliable. The optimal cutoff value of the SOC-ADL for discriminating dementia from MCI was 3 points, which provided a sensitivity and specificity of 74.5% and 75.7%, respectively. @*Conclusions@#Our results demonstrate that the SOC-ADL is a valid and reliable tool for differentiating dementia from MCI based on an assessment of ADL. This new tool can be used for screening ADL in elderly subjects who have difficulty communicating, and to increase the efficiency of dementia screening at the population level.

ABSTRACT

Objective@#This study aimed to evaluate the effect of cognitive training programs on the progression of dementia in patients with early stage Alzheimer’s disease dementia (ADD) at the day care center. @*Methods@#From January 2015 to December 2018, a total of 119 patients with early ADD were evaluated. All subjects were classified into two groups according to participate in cognitive training program in addition to usual standard clinical care. Changes in scores for minimental status examination-dementia screening (MMSE-DS) and clinical dementia rating-sum of boxes (CDR-SOB) during the 12 months were compared between two groups. Multivariable logistic regression analyses were performed. @*Results@#As compared to case-subjects (n=43), the MMSE-DS and CDR-SOB scores were significantly worse at 12 months in the control-subjects (n=76). A statistically significant difference between the two groups was observed due to changes in MMSE-DS (p=0.012) and CDR-SOB (p<0.001) scores. Multivariable logistic regression analysis showed that the cognitive training program (odds ratio and 95% confidence interval: 0.225, 0.070–0.725) was independently associated with less progression of ADD. @*Conclusion@#The cognitive training program was associated with benefits in maintaining cognitive function for patients with earlystage ADD that were receiving medical treatment.

ABSTRACT

Background@#and purpose: Appropriate medication treatment could enable both cognitively impaired patients and caregivers to hold on their cognitive functioning and quality of life. Thus, medication management and the factors influencing how management for this condition is carried out must be identified. In this study we aimed to evaluate the frequency of medication nonadherence (MNA) or drug overuse for cognitive impairment (DOC) and to extract significant variables, including the demographic and social characteristics, vascular risk factors, and cognitive status, for the diagnosis of MNA and DOC in Korean patients. @*Methods@#We investigated patients aged over 50 years between March 2019 and June 2019 via the cognitive enHancement of patIents with acQuired cognitive impairment (HIQ) campaign.MNA was defined as a participant who was classified as having cognitive impairment but did not take any cognition-related drugs, whereas DOC was defined as a participant who had normal cognition but was taking cognition-related drugs. @*Results@#We included 10,767 patients. The MNA group consisted of 337 participants, whereas the DOC group comprised 1,107 participants. The factors that could differentiate the MNA group from the normal-behavior group were age, education, sex, and the total Korean version of Mini-Mental State Examination (K-MMSE) score. The factors that could differentiate the DOC group from the normal medication-behavior group were age, sex, residential distinction, experience of a dementia screening test, and the total K-MMSE score. @*Conclusions@#The underlying factors contributing to inadequate dementia-medication management must be understood, and intervention or support is needed to enable safe medication management.

ABSTRACT

BACKGROUND AND PURPOSE: Disability associated with activities of daily living (ADL) is the basis of dementia diagnosis and is an important factor in the care of dementia patients. The status of awareness and burden of ADL disability in dementia patients was investigated six years ago and used as an important reference for “Il-sang-ye-chan” campaign. They were re-investigated in six years and compared with previous results. METHODS: The survey included caregivers of 100 dementia patients listed at the four regional dementia centers. Structured open and closed questions about ADL were asked. Assessments included age, sex, education level, economic status, severity of dementia, caregiving pattern, current statues and cognition of ADL, and caregiver needs. RESULTS: The cognition of ADL was still very low (43%). Increased stress among caregivers was the biggest burden, and they frequently suffered from outing disability (56%), recent memory loss (48%), and loss of bowel/bladder control (40%). The economic burden has been greatly reduced compared with the burden six years ago and the needs of caregivers were still highly about educational guide lines or programs. CONCLUSIONS: Continued interest and further investigation into ADL disability of dementia patients are needed. Korean Dementia Association will further expand the “Il-sang-ye-chan” program: via a multi-domain cognitive intervention program under the Care for ADL in dementia and Relieve symptoms in Dementia Project.

ABSTRACT

Leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5) has been reported to play critical roles in the proliferation of various cancer cells. However, the roles of LGR5 in brain tumors and the specific intracellular signaling proteins directly associated with it remain unknown. Expression of LGR5 was first measured in normal brain tissue, meningioma, and pituitary adenoma of humans. To identify the downstream signaling pathways of LGR5, siRNA-mediated knockdown of LGR5 was performed in SH-SY5Y neuroblastoma cells followed by proteomics analysis with 2-dimensional polyacrylamide gel electrophoresis (2D-PAGE). In addition, the expression of LGR5-associated proteins was evaluated in LGR5-inhibited neuroblastoma cells and in human normal brain, meningioma, and pituitary adenoma tissue. Proteomics analysis showed 12 protein spots were significantly different in expression level (more than two-fold change) and subsequently identified by peptide mass fingerprinting. A protein association network was constructed from the 12 identified proteins altered by LGR5 knockdown. Direct and indirect interactions were identified among the 12 proteins. HSP 90-beta was one of the proteins whose expression was altered by LGR5 knockdown. Likewise, we observed decreased expression of proteins in the hnRNP subfamily following LGR5 knockdown. In addition, we have for the first time identified significantly higher hnRNP family expression in meningioma and pituitary adenoma compared to normal brain tissue. Taken together, LGR5 and its downstream signaling play critical roles in neuroblastoma and brain tumors such as meningioma and pituitary adenoma.

ABSTRACT

With the world's fastest-growing aged population, dementia care has become a major public health concern in Korea, prompting the emergence of the policy of national responsibility for dementia care. Over the past one year since the introduction of the new policy, it has shown its strengths and weaknesses. Now is the time for us to put the current status of this policy into perspective in terms of the benefits for patients and caregivers as well as the cost-effectiveness in the management of dementia. In addition, we will suggest the optimal quality control system and education program for dementia care hospitals, highlighting the critical role of neurologists for the success of the national responsibility policy for dementia care.

ABSTRACT

As the number of dementia patients increases due to rapid aging, the burden of dementia becomes a big social problem. In response to this, various policies have been introduced in Korea. In particular, as the new policy of national responsibility for dementia care has been implemented in 2017, detailed plans for improving health care and long-term care support for dementia patients and their caregivers have been introduced. The most important thing in carrying out the comprehensive government plan will be securing sufficient the professional health and social care workforce. However, the number of neurologists to play an important role in the management of dementia will be more and more insufficient. Therefore, the need to supply an adequate number of neurologists in Korea should be discussed.

ABSTRACT

Korea is becoming an aged society at an alarmingly fast rate, which suggests that dementia care may become a major public health problem in Korea. At this point in time, the new policy of national responsibility for dementia care is a well-timed strategy, but it should be assessed based on a careful consideration of several aspects. We must promote a model of dementia care in which all members of society jointly participate. We need to improve the volunteer system in dementia care, and to make various cultural spaces for patients suffering from dementia and their family members. We need to balance financial resources and benefits in cost-reduction plans for dementia treatment. We should implement a careful quality control system for dementia care and educational programs for public dementia care hospitals and nationwide regional dementia centers. These care systems should also incorporate a health policy aiming at primary prevention to reduce the prevalence of dementia in the future. Improving the new policy of national responsibility for dementia care using detailed analyses and systematic approaches will lead to a successful dementia welfare policy.
