Focus Group-Led Refinement of an LLM-Enabled Companion Robot for Older People
Loneliness in later life is a public‐health concern, and large language model (LLM)-enabled conversational robots have potential to supplement social connection at scale by facilitating everyday conversations. However, evidence on the development and acceptability of such systems for older people remains scarce. We conducted a two‐round mixed methods study with older community‐dwelling participants, to test whether pipeline refinements—streaming …
Case report: A five−case series of 18−month home use of a conversational companion robot for psychological support in older people with mild cognitive impairment or late−onset psychosis
Although companion robots have demonstrated psychological benefits for older adults, most studies have focused on short-term use or institutional settings. This case series with integrated qualitative analysis describes five cases involving the long-term use of a conversational companion robot (RoBoHoN, Sharp) among community-dwelling women aged 85 to 90 with mild cognitive impairment or late-onset psychosis. After an initial exploratory phase (2…

Prevalence of and factors influencing Hikikomori in Osaka City, Japan: A population-based cross-sectional study
Objectives: Hikikomori is commonly defined as a social condition in which individuals avoid social participation and relationships beyond their family members by confining themselves to a room or their house for 6 months or longer. Hikikomori has been predominantly considered a problem among young people; however, as the population is ageing, hikikomori has also emerged as a social issue among adults. Nevertheless, no comparative studies have exa…
Utilizing portable electroencephalography to screen for pathology of Alzheimer’s disease: A methodological advancement in diagnosis of neurodegenerative diseases
Our findings highlight the potential of portable EEG combined with advanced deep learning techniques as a transformative tool for screening of biomarker-verified AD. This study not only contributes to the neurophysiological understanding of AD but also opens new avenues for the development of accessible and non-invasive diagnostic methods. The proposed approach paves the way for future clinical applications, offering a promising solution to the l…
Case report: Environmental adjustment for visual hallucinations in dementia with Lewy bodies based on photo assessment of the living environment
Phenomenological assessments using photographs of the patient's home could identify the environmental triggers associated with VH in patients with DLB and assist in environmental adjustments
Criteria for detection of possible risk factors for mental health problems in undergraduate university students
Academic staff should detect students who meet these criteria at the earliest and provide mental health support to reduce DUI among undergraduate university students
Predicting postoperative delirium after cardiovascular surgeries from preoperative portable electroencephalography oscillations
This study provides new insights into the objective and biological vulnerability to delirium. The developed algorithm can be applied in general hospitals without advanced equipment and expertise, thereby enabling the reduction of POD occurrences with intensive interventions for high-risk patients
Increased digital media use is associated with sleep problems among university students: A study during the Covid-19 pandemic in Japan
This retrospective cohort study investigates the association between the incidence of sleep problems and changes in digital media use among university students during the COVID-19 pandemic. It used data from annual health check-ups performed at a Japanese university in 2019 and 2020. Students undergoing these check-ups were identified to respond to questions about sleep problems, digital media use, breakfast and exercise habits, and stress. In to…
Case report: Delusional infestation in dementia with Lewy bodies
Delusional infestation may be caused by DLB. Acetylcholinesterase inhibitors (AChEI) may be effective for delusional infestation in DLB, although antipsychotics may also be needed in severe cases
Case Report: Treatment of Delusions of Theft Based on the Assessment of Photos of Patients' Homes
Evaluating patients' homes using photos could detect the environmental context of delusion of theft among patients with AD and assist in the management
Case Report: Usefulness of Biomarkers for Alzheimer's Disease in Two Cases With Very-Late-Onset Schizophrenia-Like Psychosis
The association between primary psychotic disorders emerging in later life and neurodegenerative diseases, including Alzheimer's disease (AD), is controversial. We present two female non-demented cases of psychosis with onset above the age of 60 years. Cases 1 and 2 were aged was 68 and 81 years, respectively. They suffered from persecutory delusions and scored 28 on the Mini-Mental State Examination (MMSE) at the first examination. Although deta…
Impact of Behavioral and Psychological Symptoms on Caregiver Burden in Patients With Dementia With Lewy Bodies
Background/Objective: Behavioral and psychological symptoms of dementia (BPSD) have been reported to affect caregiver burden in patients with dementia with Lewy bodies (DLB). However, the factor structure of BPSD and the factors that affect caregiver burden in DLB remain unknown. This study sought to classify BPSD and to reveal what type of BPSD affects caregiver burden in patients with DLB. Methods: We collected data on neuropsychiatric inventor…
Case Report: De Clerambault's Syndrome in Dementia With Lewy Bodies
Background: Erotomania, also known as de Clerambault's syndrome, is characterized by the delusion that a person has fallen in love with the patient. It occasionally appears secondary to psychiatric disorders and organic brain diseases. However, there have been no reports on cases secondary to dementia with Lewy bodies (DLB). Case Presentation: The patient was an 83-year-old woman who lived alone. Mild cognitive impairment appeared at the age of 8…
Characteristics of Adaptation in Undergraduate University Students Suddenly Exposed to Fully Online Education During the Covid-19 Pandemic
This study aimed to clarify the adaptation features of University students exposed to fully online education during the novel coronavirus disease 2019 (COVID-19) pandemic and to identify accompanying mental health problems and predictors of school adaptation. The pandemic has forced many universities to transition rapidly to delivering online education. However, little is known about the impact of this drastic change on students' school adaptatio…
