Korea is rapidly becoming an aging society due to lower birth rate and longer life expectancy. As elderly diseases are of a serious concern, the number of patients with dementia has been increasing significantly. For now, it has become a nationwide problem, as dementia is difficult to manage and requires a lot of social costs. To solve this, an IoT device has been devised that efficiently screens Mild Cognitive Impairment(MCI), the early stage of dementia. To design and implement the device, the latest IoT technology is introduced, the optimized Korean Version of Hasegawa Dementia Scale Revised(K-HDS) is utilized, and convenient service scenario with user-friendly design is applied. As a result, the symptoms of MCI have been screened quickly with convenient operation, which lead to the healthier society by the prevention of dementia.

Purpose: The purpose of this study was to evaluate severe periodontitis with tooth loss as a modifiable risk factor for Alzheimer dementia (AD), vascular dementia (VaD), and mixed dementia (MD) using the National Health Insurance Service-National Health Screening Retrospective Cohort database with long-term follow-up over 14 years. Methods: Multivariate Cox hazards regression analysis was applied to a longitudinal retrospective database, which was updated in 2018, to evaluate the association between severe periodontitis with few remaining teeth and dementia after adjusting for potential risk factors, including sociodemographic factors and comorbid diseases. Results: Among 514,866 individuals in South Korea, 237,940 (46.2%) participants satisfying the inclusion criteria were selected. A total of 10,115 age- and sex-matched participants with severe periodontitis and 10,115 periodontally healthy participants were randomly selected and evenly assigned. The results showed that the risks of AD (hazard ratio [HR], 1.08), VaD (HR, 1.24), and MD (HR, 1.16) were significantly higher in patients with severe periodontitis with 1-9 remaining teeth after adjustment for sociodemographic factors, anthropomorphic measurements, lifestyle factors, and comorbidities. Conclusions: Severe periodontitis with few remaining teeth (1-9) may be considered a modifiable risk factor for the development of AD, VaD, and MD in Korean adults.

Purpose: The purpose of this study was to provide a survey of patients with dementia registered and managed by primary health care posts. Method: Computation of 2016 dementia data registered in Health Care Center programs of 14 municipalities in ChoongNam province was analyzed. Data collection was done based on a pretest for dementia prevention and general management of registered dementia patients. Results: Results showed; Screening tests for dementia, 40% of population 60 or over, average number of cases, 174, average number of dementia registrants, 3.1, programs for prevention, approximately 70% special policy measures and 28% cognitive rehabilitation programs, counseling and education operating well overall, average number of dementia registrants/clinic 11.8, with women accounting for 70%, elders with less than 3 years of education, 75%, residence type cohabitation by married couples, 41%, and elders with Alzheimer type dementia, 64%. Conclusion: During early detection of dementia and follow-up examinations, high-risk groups (women, elders) should receive a dementia examination. In management of dementia there is a need to develop various programs including physical, economic, and emotional support not only for patients, but also for families. Health care managers also need systematic education to give them expert knowledge of dementia and management of dementia.

Purpose: The aim of this study was to identify the participation rate of the National Health Screening Program (NHSP) and its influencing factors by cognitive function level in Korean older adults. Methods: This study was a secondary analysis using data from the survey of the Korean Longitudinal Study of Aging in 2016. The data were analyzed using 𝑥² test and multiple logistic regression. Results: The participation rates of the NHSP in the mild cognitive impairment group (79.6%) and the suspected dementia group (58.0%) were lower than the normal cognitive function group (88.1%). The factors influencing NHSP varied by cognitive function level. Especially, in the suspected dementia group, higher participation rates of the NHSP were associated with living in rural areas, enrollment in private health insurance, no depressive symptoms, participation in social activities, and no living with children. Depression and participation in social activities influenced participation in NHSP in all groups. Conclusion: This study suggests that interventions differentiated by cognitive function level are important for increasing the participation in the health screening.

To develop a new anti-dementia acetylcholinesterase (AChE) inhibitor from edible mushrooms, AChE inhibitory activities were determined on water and ethanol extracts of various edible mushrooms from oriental medicine markets and agriculture markets. As a result, the 70% ethanol extract from Pholiota adiposa fruiting body had the highest AChE inhibitory activity of 30.6, and its water extract also had an AChE inhibitory activity of 23.8%. Therefore, we finally selected P. adiposa as a potent anti-dementia AChE inhibitor-containing mushroom. The AChE inhibitor of P. adiposa was maximally extracted when its fruiting body was treated with water for 3hr at $70^{\circ}C$ and 70% ethanol for 12 hr at $70^{\circ}C$, respectively.

Background and Purpose: We developed a new digital cognitive assessment called Seoul Cognitive Status Test (SCST), formerly called Inbrain Cognitive Screening Test. The purpose of this study was to validate the clinical utility of the SCST by comparing its scores of those with subjective cognitive decline (SCD), amnestic mild cognitive impairment (aMCI), and dementia diagnosed by the Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet (CERAD-K). Methods: All participants (n=296) who completed the CERAD-K, SCST, and Instrumental Activities of Daily Living tests were included in this study. Total score, cognitive domain scores, and subtest scores of the SCST were compared among the 3 groups (SCD, aMCI, and dementia). Additionally, correlations between SCST and CERAD-K subtests were examined. Results: Cognitive domain scores and total score of the SCST showed significant differences among the three groups, with scores being the highest in the order of SCD, aMCI, and dementia (p<0.001). Most subtests of the SCST also showed higher scores in the order of SCD, aMCI, and dementia (p<0.001). However, SCD and aMCI groups showed no significant differences in scores of the Phonemic Word Fluency Test (p=0.083) or Korean Trail Making Test-Elderly version Part A (p=0.434). Additionally, there was no significant difference in the score of Place Recognition (p=0.274) of the Word-Place Association Test between aMCI and dementia groups. Conclusions: In conclusion, differences in total score, cognitive domain scores, and subtest scores of the SCST among the 3 groups of participants diagnosed using CERAD-K confirm the clinical utility of the SCST for cognitive assessment.
