Due to the 4th industrial revolution and an aged society, many studies are being conducted to apply virtual reality to medical field. Research on dementia is especially active. This paper proposes virtual reality based on cognitive rehabilitation contents using image recognition and clustering method to improve cognitive and physical disabilities caused by dementia. Unlike the existing cognitive rehabilitation system, this paper uses travel photos that reflect the memories of the subjects to be treated. In order to generate automated cognitive rehabilitation contents, we extract face information, food pictures, place information, and time information from photographs, and normalization is performed for clustering. And we present scenarios that can be used as cognitive rehabilitation contents using travel photos in virtual reality space.

The purpose of this study was to identify the characteristics and side effects relevance of physically restrained elderly patients with dementia in the nursing hospitals. The data were collected from nursing care providers working at the 5 nursing hospitals with survey and analyzed 190 data using SPSS 21.0 program. The finding showed that age of '75 to 84' years occupied 58.3%, '17-24' hours of the total restrained time of the day 22.6%, night time 57.4% and no fall down history 54.2%. Age showed relevance with local edema and problem of joint construction(p<.05), specifically '85 and over' years having 25% occurrence in the problem of joint construction. Walking ability showed relevance with pressure ulcer, but in the patients who could walk it showed more frequency than in the patients who could not walk. The total restrained time of the day showed relevance with skin redness, local edema, problem of joint construction(p<.05). Based on this finding, it would be necessary to apply differential care policies according to the characteristics of patients when we care the restrained patients with dementia.

This study developed a occupational therapy convergent activity program to provide dementia patients admitted to the daytime ward, and investigated the program's effect on the hand and cognitive functions and instrumental activities of daily living. A total of 34 dementia patients were divided into two groups: a convergent occupational therapy program and medication were provided for 17 patients, and medication alone was provided for a control group of 17. The intervention was performed for 24 weeks, 8 times per week, 192 times in total. A handgrip strength test was performed to examine hand function before and after the intervention, and the MMSE-K and GDS were performed to evaluate cognitive function. In addition, the K-IADL was used to assess instrumental activities of daily living. With intervention, the experimental group showed significant improvements in hand and cognitive function and instrumental activities of daily living. In contrast, the control group did not show improvements in hand and cognitive function or instrumental activities of daily living. In conclusion, the study showed that a convergent/integrated activity program for occupational therapy has a positive effect on hand and cognitive function as well as instrumental activities of daily living.

Background and Purpose: The SoUth Korea study to PrEvent cognitive impaiRment and protect BRAIN health through lifestyle intervention (SUPERBRAIN) proved the feasibility of multidomain intervention for elderly people. One-quarter of the Korean population over 65 years of age has mild cognitive impairment (MCI). Digital health interventions may be cost-effective and have fewer spatial constraints. We aim to examine the efficacy of a multidomain intervention through both face-to-face interactions and video communication platforms using a tablet personal computer (PC) application in MCI. Methods: Three hundred participants aged 60-85 years, with MCI and at least one modifiable dementia risk factor, will be recruited from 17 centers and randomly assigned in a 1:1 ratio to the multidomain intervention and the waiting-list control groups. Participants will receive the 24-week intervention through the tablet PC SUPERBRAIN application, which encompasses the following five elements: managing metabolic and vascular risk factors, cognitive training, physical exercise, nutritional guidance, and boosting motivation. Participants will attend the interventions at a facility every 1-2 weeks. They will also engage in one or two self-administered cognitive training sessions utilizing the tablet PC application at home each week. They will participate in twice or thrice weekly online exercise sessions at home via the ZOOM platform. The primary outcome will be the change in the total scale index score of the Repeatable Battery for the Assessment of Neuropsychological Status from baseline to study end. Conclusions: This study will inform the effectiveness of a comprehensive multidomain intervention utilizing digital technologies in MCI.

Cognitive impairment is symptoms of dementia, a degenerative brain disease that is drawing attention in a rapidly aging society. This study was conducted to investigate the improvement of cognitive function of Leonurus japonicus on scopolamine-induced memory impairment in mice and the effect and mechanism of memory recovery. In vivo studies were conducted on mice orally pretreated with L. japonicus in doses of 50, 100 and 200 mg/kg (p.o.) and scopolamine (1 mg/kg, i.p.) were injected 30 min before the behavioral task. Antioxidant activity was assessed by 2,2-diphenyl-1-picryl hydrazyl (DPPH) assay and 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay, and acetylcholinesterase (AChE) inhibition activity evaluated by Ellman's method. In behavior studies showed that L. japonicus has an improved the memory of scopolamine-treated mice in Y-maze, passive avoidance and Morris water maze test. In addition, L. japonicus was also exerted free radical scavenging activity and inhibited acetyl cholinesterase activity. These results suggest that L. japonicus improves short-term and long-term memory in scopolamine-induced memory decline model and prevents scopolamine-induced memory impairments through in reduced oxidative stress and acetyl cholinesterase inhibition effect. Thus, L. japonicus is related to functional medicinal materials for prevention and treatment of human dementia patients.

This paper aims to propose a cognitive evaluation model to be utilized in designing game devices and developing relevant software with the purpose of the prevention of dementia of the elderly among various types of serious games for the elderly intending to improve their physical, mental or social capability. Firstly, a serious game for the elderly has been developed based on the guidelines of the areas pertaining to existing hardware, software and contents. Secondly, a pre-experiment of the game targeting specialists has been conducted in order to re-establish a cognitive evaluation model for the developed result. Thirdly, the cognitive evaluation model for the serious game for the elderly that intends to improve their cognitive capacity has been materialized based on the experiment results. Given the fact that the scope of game contents, most of which used to be focused on teenagers, have been gradually expanding to cover wider range of social classes than ever before, it is expected that the results of this study could be utilized as a model that can verify the games and their contents with special purposes based on the cognitive evaluation of the users.
