RESUMO
Objective@#As the elderly population increases, the proportion of neurocognitive disorder is increasing. Accordingly, research on cognitive intervention therapy to prevent neurocognitive disorder is also becoming active. In particular, this study attempted to evaluate changes in cognitive function before and after training and verify their effectiveness by implementing a computerized cognitive training program for patients with mild cognitive impairment. @*Methods@#A computerized cognitive training program was conducted for 15 patients with mild cognitive impairment. It was conducted twice a week, 30 minutes, and 16 times for 8 weeks, and neurocognitive function was evaluated before and after training. The neurocognitive function tests are as follows; Seoul Neuropsychological Screening Battery, Korean version of Montreal Cognitive Assessment (K-MoCA), Clinical Dementia Rating (CDR), Korean Instrumental Activity of Daily Living (K-IADL), Korean Neuropsychiatric Inventory (K-NPI), and Memory Age-associated Complaint Questionnaire (MAC-Q). @*Results@#There was a statistically significant improvement in memory domain after the implementation of the computerized cognitive training program, but no significant changes in attention, language ability, visuospatial function, and frontal lobe exec-utive function. Among the memory areas, the Seoul Verbal Learning Test: Delayed Recall, Rey Complex Figure Test: Delayed Recall, and Rey Complex Figure Test: Recognition are showed significant improvement. In addition, there was a significant im-provement in CDR (sum of box) and K-MoCA scores. There was no statistically significant difference in K-IADL and K-NPI. @*Conclusion@#Computerized cognitive training programs have been effective in improving memory in patients with mild cognitive impairment. In order to verify the effectiveness of dementia prevention, a long-term study of a larger number is needed.The results of this preliminary study will help develop and apply cognitive training contents in the future.
RESUMO
Patients with neurocognitive disorder show behavioral psychological symptoms such as agitation, aggression, depression, and wandering, as well as cognitive decline, which puts a considerable burden on patients and their families. For the treatment of behavioral psychological symptoms, patient-centered, non-pharmacological treatment should be used as a first line approach. This paper describes non-pharmacological interventions tomanage and treat behavioral psychological symptoms in patients with neurocognitive disorder. In order to control behavioral psychological symptoms such as agitation, depression, apathy, insomnia, and wandering, it is important to identify and evaluate factors such as environmental changes and drugs, and then solve such problems. Non-pharmacological interventions include reassurance, encourage, distraction, and environmental change. It is necessary to understand behavior from a patient's point of view and to approach the patient's needs and abilities appropriately. Reminiscence therapy, music therapy, aroma therapy, multisensory stimulation therapy, exercise therapy, light therapy, massage therapy, cognitive intervention therapy, and pet therapy are used as non-pharmacological interventions, and these approaches are known to improve symptoms such as depression, apathy, agitation, aggression, anxiety, wandering, and insomnia. However, the quality of the evidence base for non-pharmacological approaches is generally lower than for pharmacological treatments. Therefore, more extensive and accurate effectiveness verification studies are needed in the future.
RESUMO
Objective@#Many patients suffer from dementia in its most common form, Alzheimer’s disease (AD). In this study, the levels of IL-1β, TGF-β and CRP, which are involved in the inflammatory response in Alzheimer’s disease and its mild cognitive impairment (MCI), were measured and analyzed. @*Methods@#Seventy nine subjects participated in this study (mean age: 75.56 years, female: 54.3%, AD: 26, MCI: 28, normal: 25). The overall cognitive function of the subjects and the severity of the disease stage were assessed using the Mini-Mental State Examination (MMSE-K), the Clinical Dementia Rating (CDR), the Global Deterioration Scale (GDS) and the Geriatric Depression Scale-Korean (GDS-K). @*Results@#It was observed that patients with AD had significantly higher levels of IL-1β and TGF-β than the patients with MCI and normal controls. In addition, the MCI group showed a statistically significantly higher TGF-β concentration than the normal group. @*Conclusion@#These results suggest that IL-1β and TGF-β may be useful biological markers for patients with Alzheimer’s disease.
RESUMO
Objectives@#:The purpose of this study is to compare bleeding tendency of selective serotonin reuptake inhibitor (SSRI) and serotonin norepinephrine reuptake inhibitors (SNRI) using platelet function analyzer (PFA-100) in patients with major depressive disorder. @*Methods@#:This study is a prospective open-label study conducted by a single institution. A total of 41 subjects diagnosed with major depressive disorder under the DSM-5 diagnostic criteria participated in this study.The subjects were classified into SSRI (escitalopram) groups and SNRI (duloxetine) groups, respectively, according to random assignments. The closure time (CT) was measured using a platelet function analyzer (PFA-100) before each antidepressant was administered and after 6 weeks. Paired-sample t-test was conducted within each group to determine whether a specific antidepressant had an effect on closure time. In order to confirm the rela-tive change in platelet function between the two groups, an independent sample t-test was conducted to compare and analyze the change in closure time between the two groups. @*Results@#:There was no significant changes in closure time (CEPI-CT, CADP-CT) before and 6 weeks after drug administration in the SSRI and SNRI groups, and there was no difference in the amount of changes in closure time between the two groups. @*Conclusions@#:Our results showed no difference in bleeding tendency between SSRI and SNRI. This study suggests that further large-scale studies on bleeding tendency for various antidepressants are needed in the future.
RESUMO
Objectives@#:The aim of this study was to compare activities of daily living (ADLs) according to degenerative changes in brain [i.e., medial temporal lobe atrophy (MTA), white matter hyperintensities] and to examine the association between neurocognitive functions and ADLs in Korean patients with dementia due to Alzheimer's disease (AD) and mild cognitive impairment (MCI). @*Methods@#:Participants were 111 elderly subjects diagnosed with AD or MCI in this cross-sectional study. MTA in brain MRI was rated with standardized visual rating scales (Scheltens scale) and the subjects were divided into two groups according to Scheltens scale. ADLs was evaluated with the Korean version of Blessed Dementia Scale-Activity of daily living (BDS-ADL). Neurocognitive function was evaluated with the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease assessment packet (CERAD-K). Independent ttest was performed to compare ADLs with the degree of MTA. Pearson correlation and hierarchical multiple regression analyses were performed to analyze the relationship between ADLs and neurocognitive functions. @*Results@#:The group with high severity of the MTA showed significantly higher BDS-ADL scores (p<0.05). The BDS-ADL score showed the strongest correlation with the word list recognition test among sub-items of the CERAD-K test (r=-0.568). Findings from the hierarchical multiple regression analysis revealed that the scores of MMSE-K and word list recognition test were factors that predict ADLs (F=44.611, p<0.001). @*Conclusions@#:ADLs of AD and MCI patients had significant association with MTA. Our study, which identi-fies factors correlated with ADLs can provide useful information in clinical settings. Further evaluation is need-ed to confirm the association between certain brain structures and ADLs.
RESUMO
Objective@#This study aimed to investigate treatment effects of combination therapy of memantine and acetylcholinesterase inhibitors (AchEIs) compared with AchEIs alone on behavioral and psychological symptoms of dementia (BPSD) in patients with moderate Alzheimer’s dementia (AD). @*Methods@#This was a 12-week, double-blind, randomized, placebo-controlled trial. A total of 148 patients with moderate AD participated in this study. Mini-Mental State Examination, Neuropsychiatric Inventory (NPI), Clinician’s Interview-Based Impression of Change plus caregiver input, Gottfries–Bråne–Steen Scale, and Zarit Burden Interview were used as assessment scales. @*Results@#There were no significant differences in age, sex, or education between AChEIs alone and combination groups. The combination group showed significantly more improvement of NPI-disinhibition score (0.76±2.15) than the AChEIs alone group (-0.14±1.71) after 12 weeks. @*Conclusion@#Our findings suggest that the combination therapy of memantine and AchEIs might be a beneficial option for reducing disinhibition symptoms of patients with moderate AD compared with AchEIs alone. We believe that clinicians need to consider additional memantine treatment when patients with moderate AD complain disinhibition symptom. A larger clinical trial is needed to further determine the efficacy and advantages of such combination therapy of memantine and AchEIs for treating BPSD of patients with moderate AD.

RESUMO
Objectives@#South Korea has established four national dementia plans (NDPs). However, there have been few policy studies focusing on health services to improve the effectiveness of the NDPs. This study aimed to develop measures to raise the efficacy of medical care in NDP. @*Methods@#We classified the implementation policies of the 3rd NDP and the national dementia initiative according to the key objectives of the dementia policy of the Organisation for Economic Co-operation and Development. After investigating the progress, complementary policies were developed by reviewing the existing policy literature and exemplary cases in developed countries. @*Results@#The Community Dementia Reassurance Center should provide integrated services. To promote early screening, private medical services should be engaged. To provide post-diagnostic support, we propose a “Dementia Intensive Support Team” in hospitals. To care for severe cases of behavioral and psychological symptoms of dementia (BPSD), an “Intensive Care Unit for BPSD” is needed. It would be more effective for the various functions of the “Dementia Reassurance Hospital” to be implemented by various private medical institutions, rather than for all the functions to be implemented only by public long-term care hospitals. @*Conclusion@#Rather than carrying out all projects in the public domain, active use of private resources will increase the effectiveness and efficiency of the NDP.
RESUMO
Objectives@#:The aim of this study was to compare the effect of Selective Serotonin Reuptake Inhibitor (SSRI) and Serotonin Norepinephrine Reuptake Inhibitor (SNRI) for mood symptoms, pain, and somatic symptoms in elderly depression patients with pain and somatic symptoms. @*Methods@#:This study is a prospective open-label study conducted by a single institution. A total of 43 subjects diagnosed with major depressive disorder under the DSM-5 diagnostic criteria participated in this study (average age: 72.53, 58.1% women). The subjects were classified as SSRI and SNRI groups. Depressive symptoms, pain, and somatic symptoms were evaluated by Korean version of the Hamilton Depression Rating Scale (K-HDRS), visual analogue scale (VAS) and Patient Health Questionnare-15 (PHQ-15) respectively at baseline and six weeks later. Two-way repeated-measure ANOVA was performed to analyze changes in the KHDRS, VAS, and PHQ-15 scores. @*Results@#:In the SSRI and SNRI groups, K-HDRS, VAS, and PHQ-15 all showed significant improvement after 6 weeks compared to each baseline values. There were no differences in therapeutic effect between the two groups. @*Conclusions@#:We found that SSRI and SNRI both improved somatic symptoms and pain in elderly depression patients. The results of this study are thought to help select antidepressants when administering medication to elderly depression patients who complain pain and somatic symptoms. Further research is needed on the longterm effects of the SSRI and SNRI.
RESUMO
OBJECTIVES@#The aim of this study was to compare severity, neurocognitive functions, and behavioral and psychological symptoms of dementia (BPSD) according to the degree of temporal lobe atrophy (MTA) in Korean patients with dementia due to Alzheimer's disease and mild cognitive impairment due to Alzheimer's disease.@*METHODS@#Participants were 114 elderly subjects diagnosed with Alzheimer's disease or mild cognitive impairment in this cross-sectional study. MTA in brain MRI was rated with standardized visual rating scales (Scheltens scale) and the subjects were divided into two groups according to Scheltens scale. Severity was evaluated with Clinical Dementia Rating (CDR) and Global Deterioration Scale (GDS). Neurocognitive functions was evaluated with the Korean version of Short Blessed Test (SBT-K) and the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease assessment packet (CERAD-K). BPSD was evaluated with the Korean version of the Neuropsychiatric Inventory (K-NPI). Independent t-test was performed to compare severity, neurocognitive functions, and BPSD between two groups.@*RESULTS@#The group with high severity of MTA showed significantly lower scores in CDR, SBT-K, MMSE-KC, modified Boston naming test, word list recognition, and word list memory (p<0.05). There were no differences in K-NPI scores between two groups.@*CONCLUSIONS@#Severity and neurocognitive functions of dementia had significant positive association with MTA, but BPSD had no association with MTA. Evaluating MTA seems to have potential benefit in diagnosing and treating neurocognitive impairments in the elderly. Further evaluation is needed to confirm the association between certain brain structures and BPSD.
RESUMO
OBJECTIVES: The association between thyroid-related hormones and cognitive function has been controversial. The purpose of this study is to compare the levels of thyroid-related hormones in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). Furthermore, we investigated the relationship between thyroid-related hormones and cognitive function. METHODS: From January 2011 to December 2018, we retrospectively reviewed 105 patients who were diagnosed with AD and MCI by visiting a dementia clinic at Ilsan Paik Hospital. Thyroid-related hormones [triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH)] was measured using chemiluminescent immunoassay. An independent sample t-test was performed to analyze the mean value of thyroid-related hormones in patients of AD and MCI. To investigate whether thyroid-related hormones correlate significantly with Global deterioration scale (GDS), Clinical dementia rating (CDR) and scores of each The Korean version of the consortium to establish a registry for Alzheimer's disease items, we conducted a partial correlation analysis with geriatric depression scale-Korean version (GDS-K) scores as covariates. RESULTS: There was no significant difference in the mean serum T3, T4 and TSH levels between patients of the AD and the MCI, but the Construction Praxis Test (CPT) showed a significant positive correlation with the serum TSH concentration (p-value=0.004). CONCLUSIONS: In our study, the positive correlation between serum TSH level and the CPT associated with executive function was found to be helpful in understanding the association between thyroid-related hormones and the pathophysiology of dementia. Prospective studies in regard of the pathophysiology of thyroid-related hormones on cognitive function will be necessary in the future.

OBJECTIVES: The aim of this study is to investigate correlation between degree of white matter hyperintensities (WMH) and neurocognitive function along with behavioral and psychological symptoms of dementia (BPSD) in Korean patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI). METHODS: Participants were 115 elderly subjects diagnosed with Alzheimer's disease or mild cognitive impairment in this retrospective study. WMH in brain MRI were rated with standardized visual rating scales (Fazekas scales) and the subjects were divided into two groups according to Fazekas scale. Cognitive function was evaluated with Korean version of the consortium to establish a registry for Alzheimer's Disease (CERAD-K), and BPSD was evaluated with Korean neuropsychiatric inventory (K-NPI). Independent t-test was performed to analyze the relationship between the degree of WMH and neurocognitive functions & BPSD. RESULTS: Especially, the group with high severity of WMH showed significantly lower language fluency (p < 0.05). In addition, the group with high severity of WMH showed significantly higher score in K-NPI. CONCLUSIONS: There was a significant association between WMH and neurocognitive test related with executive function. Moreover, WMH seems to affect BPSD severity. Evaluation of WMH would provide useful information in clinical settings.

OBJECTIVE: Body composition is measured using bioelectrical impedance analysis (BIA), and correlation between the result of BIA and cognitive function is analyzed. METHODS: A total of 118 elderly (46 male, 72 female) were recruited. They were divided into three groups; normal (n=33), mild cognitive impairment (n=42), and Alzheimer's dementia (n=43) according to the diagnostic criteria. Skeletal muscle mass, body fat mass, and fat-free mass were measured using a BIA device, and were converted to the ratio of body weight. All participants underwent Korean version of Mini-Mental State Examination (MMSE-K). RESULTS: In pearson correlation analysis, skeletal muscle percentage (SMP) and fat-free mass percentage (FFMP) were positively correlated with MMSE-K score (r=0.309, p=0.001; r=0.245, p=0.008), and body fat percentage was negatively correlated (r=−0.258, p=0.005). In multiple regression analysis, SMP (β=2.012, t=4.457, p < 0.001) and FFMP (β=−1.733, t=−3.838, p < 0.001) were selected as the best predictors of changes in MMSE-K score (R2=0.198). CONCLUSION: Reduced skeletal muscle and increased body fat correlate with decreased cognitive function, suggesting the need for prevention of frailty and early diagnosis of cognitive impairment.

The term “particulate Matter (PM)” refers to the mixture of small-sized solid particles and liquid droplets floating in the air, and is referred to as PM₁₀ ( < 10 µm), PM(2.5) ( < 2.5 µm) and PM(1.0). Much PM is an anthropogenic substance generated by transportation or industrial activities, which is transformed into a second toxic substance by chemical reactions in the atmosphere. PM reaches the brain directly through olfactory transport, or through the blood-brain barrier during systemic circulation. PM that enters the local cerebral circulation causes neuroinflammation through microglial cells and endotoxins. According to previous studies, greater PM exposure results in lower brain volume, especially white matter. Among neurodevelopmental disorders, the correlation between the occurrence of autism spectrum disorder and exposure to PM is widely known. Other studies have found that exposure to PM was associated with low cognitive function and increased rate of cognitive aging. PM can also cause pathology of early Alzheimer's disease and increases the risk of Alzheimer's dementia and mild cognitive impairment.

OBJECTIVE: Depressive symptoms are common in Alzheimer's disease (AD) and they might influence the course and prognosis of AD. Depression could appear anytime in the course of the disease, and could either last considerably long or disappear easily. This study is intended to investigate the occurrence of depression in the course of AD and the risk factors of incidence. METHODS: This study targeted 1,272 AD patients without depressive symptoms at the start of this study in Korea. A total of 775 subjects completed the study, and the occurrence of depression was assessed after 12 months. Demographic information of subjects was collected and cognitive functions, overall functions, and depression severity were assessed at the start of this study and after 12 months. RESULTS: Among the 775 subjects, 103 subjects (13.29%) developed depression 12 months later. The MMSE-KC scores showed significant changes in both groups that developed depression and did not. In the univariate analysis, significant differences in the incidence of depression were found in terms of gender, the administration of the antidepressant at the baseline, the SGDS-K score, and the GDS score. The multiple logistic regression analysis showed that the increase in the incidence of depression was associated with a female, in the increase in SGDS-K score and the GDS score. CONCLUSION: The incidence of depression in the subjects who completed the 12-month follow-up observation was 13.29%. Moreover, in the multivariate analysis, a female gender and the severity of dementia, including the overall functions, seemed associated with the occurrence of depression.

OBJECTIVES: The aim of this study was to analyze the relationship between depressive symptoms and sociodemographic factors associated with geriatric depression and insomnia and to examine the effects of these factors on depression. METHODS: The severities of insomnia and depression in elderly aged 60 and older lived in Gwangmyeong city were evaluated and the related sociodemographic factors were investigated. From April 20, 2016 to December 1, 2016, Gwangmyeong city Mental Health Sevices consignment by department of psychiatry of a university-affiliated general hospital conducted surveys and interviews for total 837 elderly peoples lived in Gwangmyeong city by visiting welfare center and wards located in the city. Structured interviews were conducted using Insomnia Severity Index(ISI) and Short form-Geriatric Depression Scale(S-GDS) to examine the relationship between sociodemographic factors and the severities of insomnia and depression. RESULTS: There were significant differences in S-GDS mean scores and age(below 70 years old, 70s, 80s, above 90 years old), type of health care(health insurance, medical aid), type of residency(own, not own) and marital status(single, married, divorced or widowed).There was a significant difference in education level, especially between not educated(and/or) elementary graduates and college graduate(F=3.227, p=0.012). Also, there were significant differences in age, type of health care, type of residency, number of household on divided S-GDS score above and below 10 scores(p 0.05), but was significantly associated with depressive symptoms(p < 0.05). These findings suggest more severe insomnia symptom indicated the higher probability of depression and elderly with depressive symptoms had more severe insomnia. CONCLUSIONS: Geriatric depression has significant relationships with age, type of health care, type of residency, marital status, education and number of households. In addition, insomnia which is main symptom of depression in elderly, has important role in predicting the severity and diagnosis of depression.

OBJECTIVES: Anemia is a common problem in the management of elderly patients. Recent studies reported that anemia was associated with cognitive impairment and Alzheimer's disease. This study was aimed to analyze the differences of hemoglobin levels in Korean patients with Alzheimer's disease(AD) dementia, mild cognitive impairment(MCI), and healthy controls. Furthermore, the study also examined if any association between hemoglobin levels and cognitive functions existed. METHODS: A total of 116 Korean elderly adults were participated in this study(mean age 74.67 years ; 60.3% female). The Korean version of the Mini-Mental State Examination(MMSE-K), Clinical Dementia Rating(CDR) and Global Deterioration Scale(GDS) were applied to all subjects. Hematological and related blood chemistry values were investigated. RESULTS: We found that patients with AD dementia had significantly lower hemoglobin and hematocrit levels than MCI subjects and healthy control group. The hemoglobin levels showed a positive correlation with MMSE-K and negative correlation with CDR, GDS. CONCLUSIONS: Among Korean elderly, low hemoglobin level is associated with a cognitive impairment. This study indicates that AD is associated with anemia, and low hemoglobin levels may contribute to potentially useful clinical markers of AD. The risk factor for dementia needs to be confirmed by prospective longitudinal studies in a larger group of patients.

OBJECTIVES: Alzheimer's disease(AD) is characterized by progressive decline of cognitive function and also by various behavioral psychological symptoms of dementia(BPSD) which causes distress to their caregivers. The purpose of this study was to investigate association between each AD patients' behavioral psychological symptoms and their caregivers' burden. METHODS: Participants were 80 AD patients and their caregivers. We used Korean neuropsychiatric inventory (K-NPI) to assess the symptoms of patients and Korean version of Zarit Burden Interview(ZBI) to evaluate caregivers' burden. RESULTS: The results showed ZBI score, which is the index for caregivers' burden, had a statistically significant positive correlation with the frequency of delusion, hallucination, agitation/aggression, depression, anxiety, disinhibition and irritability, the severity of hallucination, agitation/aggression, anxiety, disinhibition, aberrant motor, and sleep, and the global score(frequency×severity) for delusion, hallucination, agitation/aggression, depression, anxiety, disinhibition, aberrant motor, and sleep. There were significant correlations between each scale for cognitive function(i.e. MMSE-KC, CDR, GDS) and ZBI scale. Correlations between each scale for activity of daily living(i.e. Barthel –ADL, K-ADL) and ZBI scale were also significant. CONCLUSIONS: There were a significant correlation between BPSD and caregiver burden. Caregiver burden was also correlated with cognitive function and activity of daily living. Early detection and preventive treatment of these symptoms in BPSD might make improvement of caregivers' quality of life as well as AD patients'.
