Purpose: This study examines the daylighting design factors of Korean dementia nursing homes, in order to realize a therapeutic environment based on the therapeutic effect of light in the rapidly aging trend with an huge increase in the population of dementia in Korea. Methods: Through literature reviews, this study aims to theoretically examine the therapeutic light environment for the elderly with dementia, derive daylighting design factors of Korean dementia nursing homes, and analyze their detailed design factors. Results: The result of this study can be summarized into two points. The first one is that the daylighting design factors reflected in dementia nursing homes are derived into six factors: building layout, windows, glazing, shading devices, spaces, and interior finishings that determine the availability of daylight. The second one is that the detailed daylighting design factors are shown as primary and secondary detailed design factors, and the main values to be considered when applying these factors into dementia nursing homes are analyzed as maximizing daylight availability, optimization of the possibility of therapeutic view, and anti-glare. Implications: The daylighting design factors will contribute to maximizing the availability of daylight, optimizing the possibility of view, and minimizing the glare in the living spaces of dementia nursing homes in Korea.

The prevention of cognitive decline and dementia is an increasingly important global public health priority due to an increase in the percentage of the elderly population. Dementia, a severe cognitive disorder, not only negatively impacts the patients' quality of life but also creates a substantial burden for caregivers. This review introduced recent advances regarding the protective effects of dairy product intake against dementia and cognitive decline. Recent epidemiological studies have suggested that specific components of dairy products including bioactive peptides, colostrinin, proline-rich polypeptides, α-lactalbumin, vitamin B₁₂, calcium, and probiotics might promote healthy brain function during aging. Additionally, oleamide and dehydroergosterol in Camembert cheese have been suggested as agents capable of reducing microglial inflammatory responses and neurotoxicity. The intake of neuroprotective and anti-inflammatory compounds in meals is safe and easy, hence nutritional approaches, including dairy product consumption, serve as a promising intervention for the prevention of neurodegenerative disorders.

Background and purpose: The anti-aging standard forest healing program (ASFHP), which uses forest therapy, was reported to be effective in improving psychological, physical, and cognitive functions. However, there are several challenges to directly visiting the forest. This study aimed to investigate the impact of multi-session ASFHP with forest visit on the mental and physical health of the older people with visits to forest facilities and compared them with those of the same program conducted indoors. Methods: Individuals aged over 70 years with concerns about cognitive decline were recruited at dementia relief centers and divided into control and experimental groups. A total of 33 people were administered ASFHP under the supervision of a forest therapy instructor. The control group stayed indoors, while the experimental group visited a forest healing center and repeated the program 20 weeks. Results: The multiple-session ASFHP positively affected cognitive impairment screening test (CIST) total scores (p=0.002), memory (p=0.014), Korean version of the Repeatable Battery for the Assessment of Neuropsychological Status total scores (p<0.001), immediate recall (p=0.001), visuospatial/construction (p<0.001), language (p<0.001), forest healing standard questionnaire total scores (p=0.002), and cognitive function (p=0.019), regardless of location. The forest visits during the ASFHP showed positive effects on orientation (p=0.035), delayed recall (p=0.042), emotional stability (p=0.032), physical activity (p=0.005), and health (p=0.022). The CIST scores of the memory domain were the strongest indicator of the multiple-session ASFHP effects. Conclusions: The 20-week multi-session ASFHP with forest visit showed effects on cognitive improvement and physical and emotional stability compared to indoor education.

Alzheimer's disease is a neurodegenerative disorder associated with a decline in cognitive abilities. Dementia is one of the aged related mental problems and a characteristic symptom of Alzheimer's disease. Nootropic agents like piracetam and cholinesterase inhibitors like $Donepezil^{\circledR}$ are used in situations where there is organic disorder in learning abilities, but the resulting side-effects associated with these agents have limited their utility. Foeniculum (F.) vulgare Linn. is widely used in Indian traditional systems of medicines and also as a house remedy for nervous debility. The present work was undertaken to assess the potential of F. vulgare as a nootropic and anti-cholinesterase agent in mice. Exteroceptive behavioral models such as Elevated plus maze and Passive avoidance paradigm were employed to assess short term and long term memory in mice. To delineate the possible mechanism through which F. vulgare elicits the anti-amnesic effects, its influence on central cholinergic activity was studied by estimating the whole brain acetylcholinesterase activity. Pretreatment of methanolic extract of fruits of F. vulgare Linn. for 8 successive days, ameliorated the amnesic effect of scopolamine (0.4 mg/kg) and aging induced memory deficits in mice. F. vulgare extract significantly decreased transfer latencies of young mice and aged mice, increased step down latency and exhibited significant anti-acetyl cholinesterase effects, when compared to piracetam, scopolamine and control groups of mice. F. vulgare might prove to be a useful memory restorative agent in the treatment of dementia seen in the elderly.

Therapeutic effect of a Kampo medicine, Choto-san, in patients with vascular dementia was demonstrated by a double-blind and placebo-controlled clinical trial. To clarify the therapeutic efficacy of Choto-san, anti-ischemic effect in mice, hypotensive effect in spontaneously hypertensive rats (SHR), anti-oxidative effects in vitro, and N-methyl-D-aspartate (NMDA) receptor-blocking activity using Xenopus oocytes were studied. (1) Pretreatment with Choto-san (0.75-6.O g/kg, P.O.) or a component herb Chotoko (Uncaria genus: 75 - 600 mg/kg, P.O.) prevented ischemia-induced impairment of spatial learning behaviour in mice. Indole alkaloids- and phenolic fractions extracted from Chotoko also improved significantly the learning deficit. (2) Subchronic administration of Choto-san (0.5 g/kg, p.o.) caused a significant hypotensive effects in SHR. (3) Choto-san, Chotoko, and the phenolic constituent, (-) epicatechin, significantly protected the NG108-15 cell injury induced by $H_20_2$ exposure in vitro and also inhibited lipid peroxidation in the brain homogenate. (4) Indole alkaloids, rhynchophylline and isorhynchophylline (1-100 uM), reversibly reduced NMDA-induced current in the receptor-expressed Xenopus oocytes. These results suggest that anti-vascular dementia effects of Choto-san are mainly due to the effect of Chotoko. From these results, it is possible to make a novel dietary supplement through several extraction steps from Chotoko.

We report a case of an 80-year-old Korean man with chronic cerebral paragonimiasis who presented with progressive memory impairment. He suffered from pulmonary paragonimiasis 60 years ago and has been experiencing epilepsy since the age of 45. He began experiencing memory and cognitive deterioration 3 years ago. He visited the neuropsychiatric department of our hospital to check his symptoms and health from a year ago. Contrast-enhanced brain magnetic resonance imaging study revealed calcifications and cystic lesions encompassing the right temporo-occipital region. Encephalomalatic changes were also observed in the right occipital and temporal areas. The anti-Paragonimus specific IgG antibodies in his serum showed a strong positive response. The neuropsychological test results showed a Global Deterioration Scale of 4 and a Clinical Dementia Rating Scale of 1. The chronic cerebral paragonimiasis lesions in the patient's right temporo-occipital region might induce the dementic change.
