Depression evolves dynamically in old age. Studies of natural history of major depression in older adults suggest that 19–34% recover, 27%–32% remain chronically ill, and approximately 40% experience a fluctuating course. Another way of approaching depression from a longitudinal point of view is by adopting a symptom-based approach, that in addition to the evolution of clinically manifested diagnostic entities, also focuses on transitions involving subclinical/subsyndromal states, although few studies have attempted it. We examined psychosocial, behavioral, and clinical determinants of transitions across states that include no depression, subsyndromal-, and clinical depression.

We used data on 3086 adults aged 60+ from the Swedish National Study on Aging and Care in Kungsholmen, followed for 15 years. Markov-state transition models were used to capture transition patterns, as well as their associated determinants. Death and dropout constituted absorbing states. Depression was diagnosed in accordance with DSM-5; SSD was based on having at least 2 symptoms in the absence of DSM diagnosis. Determinants of transition patterns included index of social connections and support (i.e., psychosocial determinants); smoking, alcohol consumption, and physical activity (behavioral determinants); somatic disease burden and history of depression (clinical determinants).

At baseline, 10% of the study population exhibited clinically relevant levels of depressive symptoms. Over a 15-year period, a total of 11,489 transitions were observed. Preliminary results indicate that behavioral factors (primarily smoking) were mostly associated with transitions from no depression to clinical depression, as well as from clinical depression to death. Mostly the same pattern was seen for clinical determinants, although higher burden of chronic diseases and previous depression also increased the likelihood of transition from no depression to SSD. Notably, of high baseline values of social connection and support were found to: 1) lower the likelihood of transitioning from no depression to either SSD or clinical depression; 2) lower the likelihood of transitioning from SSD to clinical depression; and 3) increase the likelihood of transitioning from clinical depression to no depression.

Clinical and behavioral factors are mostly implicated in lowering the occurrence of depression, whereas psychosocial factors may also be implicated in recovery.

Dementia risk varies along the social gradient, which needs to be considered in risk reduction and prevention strategies. Revealing links of social determinants of health (SDOH) and modifiable health and lifestyle factors for dementia holds clues towards maximizing dementia risk reduction opportunities, especially for vulnerable populations. Therefore, the aim was to investigate associations of SDOH and a dementia risk score in Indigenous Māori and Non-Māori (mainly European descent) in midlife and early late-life.

A subsample of the New Zealand Health, Work and Retirement study completed standardized face-to-face cognitive assessments (adapted ‘Kiwi’ Addenbrooke’s Cognitive Examination/ACE-R) in 2010. We computed the Lifestyle for Brain Health (LIBRA) dementia risk score, comprising 8 risk factors (low/moderate alcohol consumption, heart disease, physical inactivity, chronic kidney disease, diabetes, smoking, hypertension, depression). Higher scores indicate higher dementia risk/poorer lifestyle (range= -1;+9.2). First, we assessed associations of LIBRA and cognition. Second, we performed adjusted regression analysis for area-based (socioeconomic deprivation, health care access, neighbourhood safety) and individual SDOH (education, employment status, net income, social loneliness) with LIBRA stratified for Māori and Non-Māori.

In 918 participants (age: M= 62.9 years, SD= 6.7, range= 48-75; females= 52.8%; Māori= 26.2%), a higher LIBRA score (M= 1.8, SD= 1.6, observed range= -1; +7.4) was associated with lower cognitive functioning (b= -0.30, 95%CI= [-0.48;-0.11], p= .002) and cognitive impairment (OR= 1.41, 95%CI= [1.10;1.81], p= .007), adjusted for age, sex, education, ethnicity and area-based socio- economic deprivation. Higher area-based socio-economic deprivation was associated with higher LIBRA in Māori (b= .10, 95%CI= [0.02;0.18], p= .020), but not in Non-Māori (b= 0.01, 95%CI= [- .03;0.05], p= .677). Employment status and lower neighbourhood safety were associated with higher LIBRA in Non-Māori only. Health care access difficulties and social loneliness were associated with higher LIBRA in both populations, while education and net income were not.

SODH are differentially associated with dementia risk in midlife and early late-life New Zealanders. Area-based socioeconomic deprivation was linked to dementia risk in Indigenous Māori, but not in Non-Māori. This points to systematic inequities in dementia risk, which require equity- focused policy-based public health approaches to risk reduction.

Depression is the most frequent cause of emotional distress in old age and can reduce the quality of life of the elderly. Sarcopenia is a syndrome characterized by the loss of skeletal muscle associated with reduced physical strength/performance. In recent years, some studies have shown correlations between sarcopenia and depression. The aim of the present study is to evaluate the association between depressive symptoms, sarcopenia, functional dependence and comorbidity in the geriatric patient at the first geriatric outpatient evaluation ever performed.

older adults (>=65 years of age) at their first access to the geriatric outpatient clinic of Modena County (Italy) between October 2020 and June 2021 were enrolled in this cross-sectional study. All participants were evaluated validated scales in order to perform a multidimensional geriatric assessment. The symptomatologic diagnosis of depression was performed through the GDS 4-item (cut-off >=2). Frailty was evaluated through the Clinical Frailty Scale (cut-off >=5). The probability of sarcopenia was evaluated through the SARC-F (cutoff >=4). Functional dependence was assessed through the ADL scale and deemed as severe (ADL 0-2), moderate (ADL 3-5), absent (ADL 6). Comorbidity burden was assessed through CIRS.

229 patients (mean age 82.4±7.9 years, 67.6% female) were evaluated. Clinically significant depressive symptoms were found in 173 (75.5%) patients. Probable sarcopenia was reported in 118 (51.5%) patients while 100 (43.7%) and 64 (27.9%) patients were moderately or severely dependent, respectively. At multivariate logistic regression, probable sarcopenia (aOR 2.48, 95%CI 1.09-6.40), moderate functional dependence (aOR 2.62, 95%CI 1.17-5.87) but not severe (aOR 2.72, 95%CI 0.79-9.33) were associated with the presence of depressive symptoms. Conversely, frailty (aOR 0.97, 95%CI 0.39-2.40) was not associated with presence of depressive symptoms, while CIRS (aOR 0.79, 95%CI 0.66-0.96) was found to be protective.

the study showed that a clinically relevant depressive symptomatology is prevalent among older adults and it is associated with higher probability of sarcopenia and moderate, but not severe, functional dependence. On the contrary, there was no association between depressive symptoms and frailty.

The prevalence of depressive symptoms is high among geriatric outpatient and can both be conditioned by and have an impact on the presence of sarcopenia and functional dependence.

Research tends to focus on the issues couples face – i.e., the dyadic relationship between carers and the affected person. This study examined young onset dementia from the broader family systems approach, focusing on the impact on the entire family following a diagnosis.

Public patient involvement was utilised to explore the specific issues of relevance to people with young onset dementia. Participatory workshops with members of the Alzheimer Society of Irelands Dementia Research Advisory Team were held to develop questions for the focus group interviews. Focus group interviews involved people with young onset dementia and their family members. The sample (n = 44) included people with a formal diagnosis of young onset dementia (with various subtypes) living in the community, and their family members including children.

Analysis of the qualitative data uncovered five main themes with related sub-themes including: initial onset of dementia; personal and social impact; behavioural and psychological symptoms of dementia; age-appropriate support and the shifting family roles.

It is clear from the current data that a diagnosis of young onset dementia results in significant challenges for the entire family system. The traditional model of care, which tends to narrow the focus to the person with dementia and primary caregiver, needs to be expanded to include the entire family/caregiving system.

Western countries have a significant cohort of children (≤ 18) and young adults who live with a parent with a life limiting condition. Children and young adults’ perspectives of certain parental illnesses have been well documented. However, the perspectives of children and younger adults of parental young onset dementia tend to be absent from the academic literature. Older adult children have reported on the impact parental young onset dementia, however, there is a necessity for research with younger adult children and children under the age of eighteen in relation to their perspectives of the condition.

Utilizing cultural transmission theory, the current research explored if the social and cultural perspective influences the narratives of children and younger adults of parental young onset dementia.

One-to-one interviews were held with children and younger adults (n = 17: 29·41% male) who currently live with (or have lived with) a parent with a formal diagnosis of young onset dementia (with various subtypes). The participants ranged in age from 14 to 33 years old (x̅ = 21·18 years) with n = 6 eighteen years of age or younger (x̅ = 16·17 years). Participant narratives were analyzed using inductive qualitative thematic analysis.

Detailed thematic analysis of the participant narratives uncovered five main themes (with related subthemes); making sense; lack of representation; threat to the family system; life has completely changed; systemic psycho-social support and education.

It is clear from the current data that the social and cultural perspective can significantly influence the narratives of children and younger adults of parental young onset dementia. Children are faced with more responsibility, shifting roles, changing relationships, and may be forced to postpone educational or employment plans. Furthermore, the social perception of dementia as can act as a barrier to children and young adults accessing and using health and social care providers.

Social health (SH) markers, including marital status, contact frequency, network size, and social support, have been linked with increased cognitive capability. However, the underlying mechanisms remain poorly understood. We aim to investigate whether depression symptoms and inflammatory biomarkers mediate associations between SH and cognitive outcomes.

We used data from waves 1-9 of the English Longitudinal Study of Ageing, involving 7,136 participants aged 50 or older at baseline. First, we examined associations between SH (wave 1) and depression and inflammatory biomarkers (C-reactive protein (CRP) and fibrinogen) (wave 2) using linear regression models. Second, we tested associations between a) SH and b) depression and inflammation with subsequent standardised verbal fluency and memory in wave 3 and change between waves 3-9, indexed using slopes derived from multilevel models. We adjusted for age, sex, socio-economic position, cardiovascular disease, basic and instrumental activities of daily living, health behaviours, and baseline depression symptoms and cognition. We will also conduct causal mediation analysis.

All SH markers, except contact frequency, were associated with lower subsequent depression, but not inflammatory biomarkers. Greater contact frequency (e.g. once-twice a week vs <once per year: β=0.18 [0.01, 0.36]) and less negative support (β=0.02 [0.00, 0.03]) were associated with higher verbal fluency. Larger network size (>6 people vs none: β=0.007SD/year [0.001, 0.012]), less negative (β=0.001SD/year [0.001, 0.002]) and more positive support (β=0.001SD/year [0.000, 0.001]) were linked with slower memory decline, and more positive support predicted slower verbal fluency decline (β=0.001SD/year [0.000, 0.001]). Depression symptoms were associated with lower memory and verbal fluency, and faster memory decline (β=-0.001SD/year [-0.001, -0.000]) and verbal fluency (β=-0.001SD/year [-0.001, -0.000]). CRP was associated with lower verbal fluency (β=-0.02 [-0.04, 0.00]), whereas fibrinogen was linked with faster memory decline (β=-0.001SD/year [-0.003, -0.000]).

Depression symptoms and SH showed associations with subsequent cognitive capability and change. SH was linked with lower depression, but not inflammatory biomarkers. Findings highlight the potential for depression to underpin associations between SH and cognition, a pathway which we will test using causal mediation analysis. We will also examine whether findings replicate in the Swedish National Study of Aging and Care in Kungsholmen.

Reminiscence therapy is the examination of past memories to improve current mood and psychological functioning and is an evidence-based treatment for symptoms of late life psychological distress. Music is sometimes used in such therapy to prompt or enhance the recollection of memories; however, there is limited empirical research on the use and value of using music in reminiscence therapy. This presentation will discuss the findings of two studies exploring the feasibility and use of verbal reminiscence therapy (VRT) and music-assisted reminiscence therapy (MRT) from the perspectives of the older adult and the staff who care for them.

Study one surveyed 110 Australian workers in aged care to explore the extent to which VRT and MRT were used, how such interventions were delivered and viewed, and the benefits. Study two randomly assigned 8 older adults experiencing psychological distress to a single session of VRT or MRT. Pre and post measures of affect, memory experience, and a brief satisfaction interview were collected, along with measures of treatment fidelity.

For staff, simple reminiscence was the most frequently used approach across both VRT and MRT. Staff reported that both VRT and MRT are viewed as successful and regularly used interventions, that occur in spontaneous and creative ways in response to older clients’ needs. Staff reported outcomes such as enhanced social connections, improved affect and mood, and better care practices. Older adults reported that that VRT and MRT were equally acceptable and well tolerated. A pre-post pattern of improvement was observed for affect following VRT, and particularly MRT, suggesting both as promising interventions. MRT resulted in higher scores on memory experience characteristics such as vividness, coherence, and accessibility. The high treatment fidelity achieved in this study indicates that the interventions can be successfully implemented with this population.

VRT and particularly MRT were viewed as successful, feasibility and acceptable interventions by older adults experiencing psychological distress, and direct care staff in Australia. These preliminary findings indicated MRT may provide therapeutic changes above and beyond VRT for older adults, and therefore large-scale clinical trials are warranted.

Treatment of idiopathic normal-pressure hydrocephalus (iNPH) requires collaboration between dementia specialists and neurosurgeons. The role of dementia specialists is to differentiate patients with iNPH from patients with other dementia diseases and to determine if other dementia diseases are comorbid with iNPH. We conducted a nationwide hospital-based questionnaire survey on iNPH in medical centers for dementia (MCDs).

We developed a questionnaire to assess how physicians in MCDs evaluate and treat patients with cognitive impairment due to suspected iNPH and the difficulties these physicians experience in the evaluation and treatment of patients. The questionnaire was sent to all 456 MCDs in Japan.

Questionnaires from 279 MCDs were returned to us (response rate: 61.2%). Patients underwent cognitive tests, evaluation of the triad symptoms of iNPH, and morphological neuroimaging examinations in 96.8, 77.8, and 98.2% of the MCDs, respectively. Patients with suspected iNPH were referred to other hospitals (e.g., hospitals with neurosurgery departments) from 78.9% of MCDs, and cerebrospinal fluid (CSF) tap test was performed in 44 MCDs (15.8%). iNPH guidelines (iNPHGLs) and disproportionately enlarged subarachnoid space hydrocephalus (DESH), a specific morphological finding, were used and known in 39.4% and 38% of MCDs, respectively. Logistic regression analysis with “Refer the patient to other hospitals (e.g., hospitals with neurosurgery departments) when iNPH is suspected.” as the response variable and (a) using the iNPHGLs, (b) knowledge of DESH, (c) confidence regarding DESH, (d) difficulty with performing brain magnetic resonance imaging, (e) knowledge of the methods of CSF tap test, (f) absence of physician who can perform lumbar puncture, and (g) experience of being told by neurosurgeons that referred patients are not indicated for shunt surgery as explanatory variables revealed that the last two factors were significant predictors of patient referral from MCDs to other hospitals.

Sufficient differential or comorbid diagnosis using CSF tap test was performed in a few MCDs. Medical care for patients with iNPH in MCDs may be improved by having dementia specialists perform CSF tap tests and share the eligibility criteria for shunt surgery with neurosurgeons.

Psychotic disorders are not infrequent in late life and involve massive costs to society, affecting individuals and their caregivers. The epidemiology of late-life psychosis remains imprecise and despite its high prevalence, it remains a diagnostic and treatment dilemma. The aim of this article is to review the current literature regarding late-onset psychosis and whether it is recognized as a clinical entity on itself, differing from early-onset psychosis.

Review of the most recent literature regarding late-onset psychosis its clinical and epidemiological particularities. The research was carried out through the PubMed and UptoDate databases, using the terms “late-onset psychosis”, “late-life psychosis”, “dementia” and “elderly”.

Late-life psychotic disorders may originate in an intricate interaction between several biological, psychological, social, and environmental factors. These may include functional status, other physical diseases, hospitalizations, physical activity, and stability of care. Some authors refer that older age, and the presence of suicidal ideation were associated with incident late-life psychosis. Assuming the significant load associated with psychotic disorders in late life, their assessment should identify the potential causes and distinguish predictive factors. Treatment should include a combination of nonpharmacological approaches and psychotropic medications, used cautiously.

Late-life psychosis differs from early-onset psychosis on several characteristics. The treatment must be directed towards the cause and adapted to each individual. Non-pharmacologic interventions are frequently used as first line treatment, and pharmacotherapy must be used carefully. The crescent number of senior population must alert to this entity and the specificity of its approach.

Older adults are at greater risk for developing severe illness from SARS-COV2 infection and may be more vulnerable to negative mental health outcomes as a result of public health guidelines that increase social isolation. We assessed mental health outcomes in older adults with normal cognition (NC), past history of major depressive disorder (i.e., remitted; rMDD), or mild cognitive impairment (MCI) to determine the prevalence of depression, anxiety, general stress, and post-traumatic stress during the COVID-19 pandemic and the impact of diagnosis and sex.

The sample included 108 older adults (37 males, mean age=72.1 years): 71 older adults with normal cognition (NC) based on normal neuropsychological test performance and no psychiatric history, 21 rMDD participants based on DSM5 criteria, and 16 MCI participants based on NIA-AA criteria. Participants completed self-report measures of depression [Patient Health Questionnaire-9 (PHQ-9)], anxiety [Patient-Reported Outcomes Measurement Information System (PROMIS)], general stress [Perceived Stress Scale (PSS)] and post-traumatic stress [Impact of Events Scale Revised (IES-R)] through video- or teleconferencing. Prevalence rates of clinically significant psychiatric symptoms were expressed as the percentage of participants with total scores that exceed the normal cut-offs. Separate MANOVAs were used to examine the effects of diagnosis and sex. Non-normally distributed data (PHQ-9 and PROMIS total scores) were rank-transformed.

Approximately 1/3rd of participants endorsed clinically significant symptoms based on scores exceeding the cut-off for normal: 33.7% on PHQ-9, 31.3% on PROMIS-Anxiety, 35.5% on PSS, 38.3% on IES-R. rMDD participants scored higher on all measures compared to NC participants (p’s < .005) while MCI participants scored higher on the PSS compared to NC (p=.035). Women scored higher on all measures compared to men.

These rates of approximately 1/3rd reporting clinically significant symptoms of depression, anxiety, general stress, and post-traumatic stress are higher than those described in population surveys of older adults but are comparable to prevalence rates of psychiatric symptoms in the general adult population. The effects of diagnosis and sex indicate that older adults with previous depression or current MCI, as well as women overall, are particularly vulnerable to developing clinically significant psychiatric

Motoric cognitive risk syndrome (MCR), which is defined as a pre-dementia syndrome characterized by subjective cognitive complaints and slow gait in older individuals free of dementia and mobility disability, has been associated with increased risks of dementia, functional dependence, and mortality. The aims of this study were to describe the prevalence and distribution of MCR and to explore the clinical profiles associated with MCR in rural-dwelling older adults.

The population-based cross-sectional study included 5,021 dementia- and disability-free participants (age ≥60 years; 56.48% women) in the baseline assessments (March-September 2018) of the Multimodal Interventions to delay Dementia and disability in rural China (MIND-China). The MCR syndrome was diagnosed when the participants had subjective memory complaints and gait speed ≥1 standard deviation (SD) below the age- (<75 and ≥75 years) and sex-specific means. We estimated the age- and sex-specific prevalence of MCR. We used logistic regression models to examine lifestyle and clinical factors associated with MCR while controlling for age, sex, and education.

The overall prevalence of MCR syndrome was 13.58%, with the prevalence being 11.53% in males and 15.16% in females (P<0.001). The prevalence of MCR was increased with age, from 10.43% in people aged 60-69 years and 15.97% in those aged 70-79 years to 21.71% among those aged ≥80 years. The demographic-adjusted odds ratio (95% confidence interval) of MCR was 1.30 (1.08-1.57) for being overweight (body mass index 24-27.9 vs. <24 kg/m2), 1.65 (1.32-2.05) for having obesity (≥28 kg/m2), 1.74 (1.41-2.15) for diabetes, 1.44 (1.20-1.73) for dyslipidemia, 1.59 (1.32-1.91) for having coronary heart disease, 2.17 (1.78-2.65) for having stroke history, 1.52 (1.24-1.86) for having osteoarthritis, and 3.40 (2.70-4.28) for having depressive symptoms. Ever (vs. never) smoking and alcohol consumption were related to odds ratio of 0.65 (0.48-0.86) and 0.71 (0.55-0.91), respectively, for MCR syndrome.

The MCR syndrome affects nearly 1 in 7 Chinese rural older adults, and the MCR prevalence appears to be higher in women than in men. Cardiometabolic risk factors (e.g., overweight/obesity, diabetes, and dyslipidemia), osteoarthritis, coronary heart disease, stroke, and depressive symptoms were associated with increased likelihoods of the MCR syndrome.

Deinstitutionalization of nursing care in European counties relies profoundly on the mobilization of the caregivers and municipal homecare services. Yet, caring for home-dwelling people with dementia (PwD) can be stressful and resource demanding. The LIVE@Home.Path trial tailored, implemented, and evaluated the multicomponent LIVE intervention on informal caregivers’ burden in dyads of home-dwelling PwDs and their families.

From 2019 to 2021, we conducted a 24-month multicenter, multicomponent, stepped-wedge randomized control trial including dyads of people ≥65 years with mild to moderate dementia with minimum 1h/week contact with their informal caregiver. The user-developed Learning, Innovation, Volunteer support, and Empowerment (LIVE) intervention was implemented by municipal coordinators over 6 months periods. In an intention-to-treat analysis, we applied mixed-effect regression models accounting for time and confounding factors to evaluate the effect of the intervention on Relative Stress Scale (RSS), Resource Utilization in Dementia (RUD) and Clinical Global Impression of Change (CGIC).

A total of 280 dyads were included at baseline, mean age of PwD was 82.2 years, 63% female, 43% lived alone, 36% had Alzheimer’s dementia, median MMSE was 20 (range 0-30) and median FAST score 4 (range 1-7). Caregivers were on average 66 years, 64% female, 49% were the PwDs child. At baseline, 80 dyads were randomized to intervention sequence 1 of which 67 received the intervention, corresponding numbers for sequence 2 and 3 were 97/ 57 and 103/50. During the active intervention period, time spent in personal activities of daily living significantly increased with 2.8 hours/months compared to 1.2 hours/months increase in the control period, total score of RSS was stable in the intervention period (0.36 points) (range 0-60), while it increased significantly in the control period (27.0 points), CGIG increased significantly only in the intervention period (0.5 points) (range: -5 worsening, 5 improvement).

Although caregivers reported more care time during the intervention periods, they did not experience more stress which may be related to their increased understanding of dementia. Increase in reported care time might also reflect the increased understanding of dementia, leading to more realistic evaluation of own time contribution.

Residential care facilities (RCFs) provide 24/7 care to older adults with cognitive and/or physical disabilities. RCFs aim to provide person-centred care (PCC) to enhance the quality of life (QoL) of residents. Residents are dependent on their environment to fulfil their needs and wishes, such as drinking alcohol or smoking tobacco. Although alcohol and tobacco use can be experienced as a part of QoL in the final phase of life and the motivation to quit these substances is low, it can cause severe health problems in older adults. In RCFs this may cause a dilemma between the QoL of individual residents and the health and safety problems of all residents. This study aims to explore multiple perspectives on alcohol and tobacco use within the RCF.

A qualitative research design was chosen, and semi-structured interviews were conducted. A various sample was purposively selected in two organizations on two types of units (psychogeriatric units and units providing care for residents with mainly physical disabilities): residents who use alcohol and/or tobacco and those who do not. Subsequently, four of these 16 residents were invited to participate in an in-depth case study. To explore the dynamics of the social environment, both formal and informal caregivers were invited to participate.

Residents are satisfied with their current use and value their autonomy regarding alcohol and tobacco use. Residents acknowledge that their use could cause a nuisance to others. Multiple caregivers are involved in their use and residents experience dependency on these caregivers to smoke tobacco or drink alcohol. There was limited interaction between the residents and their (in)formal caregivers and amongst the caregivers on this topic. Moreover, caregivers tended to act from their own perspectives, based on their professional expertise, knowledge, and attitudes towards residents’ alcohol and tobacco use.

A dilemma arises between protecting residents from the adverse (health) outcomes of alcohol and tobacco use and sustaining their QoL by optimizing their autonomy. Future research could assess how to integrate providing PCC to residents by offering choices and autonomy, while considering the addictive component of these substances, health, and safety risks for all.

Suicidal behaviors represent a serious public health problem in terms of mortality, morbidity and social impact. Suicide in the elderly is a statistical reality little studied in the Latin American context. Method: It´s an observational study where we reviewed the records of the patients seen between January 2018 and December 2019 at the Psychogeriatrics Clinic of the Ramón de la Fuente Muñiz National Institute of Psychiatry; collecting sociodemographic, clinical information and evaluating the suicidal risk by the SAD PERSONS Scale. With the information obtained, we correlated variables with suicidal risk based on the Pearson and Spearman correlation indices.

A total of 404 files were reviewed, finding that in the last 5 years 1.4% of the patients had made a suicide attempt, what was directly related to a history of violence (r=0.256, p=0.011). Suicidal thoughts in the past year (15.4%) and increased suicidal risk were associated with PAS use (r=0.123, p=0.037) (r=0.207, p=0.001) and depressive disorder (r=0.148, p=0.012) (r=0.27, p=0.000).

In the older adult population, some of the clinical and sociodemographic factors associated with suicidal risk described for the general population could continue to be considered risk factors, among them: being male, low level of education, diagnosis of depressive disorder, having medical comorbidities and the use of SPA.

Episodes of lucidity (EL) are clinically and potentially epidemiologically significant events that occur among individuals with advanced dementia. EL are characterized by a spontaneous return of abilities previously thought to have been lost and are predominantly reported near end of life. Audiovisual observation offers a valuable approach to studying EL, providing opportunities to characterize verbal/non-verbal features of EL as well as their surrounding contexts. Approaches to capturing and characterizing audiovisual data and potential verbal/non-verbal indicators of EL near end of life are lacking.

This study determined the acceptability and feasibility of a multi-faceted observational study protocol to characterize potential observable indicators of EL among people with advanced dementia near end of life.

This study incorporated longitudinal audiovisual observation, informant field interviews/case review of potential EL events by informants. We examined enrollment and retention rates, task load and usability ratings from clinician and research staff across data collection and processing tasks, and surveys and qualitative appraisal from participants and staff regarding feasibility and acceptability. The NASA TLX Task Load Index measures workflow assessment to generate a combined score between 0-20, with 0 indicating higher workflow assessment. The modified System Usability Scale (SUS) measures usability with a score of 0-100, with 100 indicating higher usability and a target score ≥68 indicating usability higher than 50% of the average score.

Five eligible individuals were enrolled, yielding a 100% enrollment/retention rate, and 103 observations totaling 280 hours of observation across participants. NASA TLX Task Load Index scores of 2.9 over 4 months, with vast improvement over time indicate study procedures with iterative refinements were feasible. Average modified SUS score for clinician and research staff was 96 and 82.4 respectively, indicating high usability with notable improvement over time. Surveys and qualitative appraisal from participants and staff endorse high rates of acceptability and feasibility. Additionally, the study team identified 9 potential EL across 3 participants. Seven caregivers and two clinicians participated in case reviews to review the corresponding audiovisual data, resulting in 3 endorsed EL.

Treatment-resistant depression (TRD) is not uncommon in older people. Brain stimulation, such as 4-6 weeks of repetitive transcranial magnetic stimulation (rTMS) or theta burst stimulation (TBS) targeting the left dorsolateral prefrontal cortex, has been evidenced as an essential intervention for adult TRD and also documented in the current international treatment guideline. In 2018, Taiwan Food and Drug Administration cleared the rTMS as a treatment option for TRD and now rTMS is still a treatment at their own expense in Taiwan. Additionally, prolonged intermittent TBS (piTBS) protocol has been proven its similar antidepressant efficacy as standard 4-6 weeks rTMS/iTBS in adult TRD, but in a shorter treatment course of 2 weeks. For older adults with depression, 4-6 weeks of treatment course may burden their caregiver due to their limited ambulation and transportation ability. However, hitherto there was no study to investigate the antidepressant efficacy of left-sided prefrontal piTBS in treating older TRD.

A chart review was performed at a single Taiwan hospital from 2018 to 2020. 17-items Hamilton Depression Rating Scale (HDRS-17) was measured before and after the piTBS intervention. Maudsley Staging Method was used for the depression treatment refractoriness.

We identified 23 old adults with TRD (mean [SD] age, 66.0[5.2]; 78% female) who underwent 10-20 sessions of daily piTBS (1800 pulses/session; 10sessions, n=18, 15sessions,n=4, 20session,n=1). On continuous outcomes, mean(SD) HDRS-17 total scores improved from 20.5(6.62) to 11.8(7.7) after receiving piTBS intervention. The mean percent improvement of HDRS-17 was 46.0%±29.4%. Dichotomous outcomes showed response rate of 43.5% and remission rate of 34.8%. No seizures or other serious adverse events were noted, and no premature discontinuation was noted.

This study is the largest study demonstrating the piTBS protocol provides a comparable reduction in depression symptoms in older adults with TRD, similar to the effectiveness in adult TRD and the efficacy of standard sequential bilateral rTMS/iTBS in older TRD in the FOUR-D trial. Regarding desirable efficiency and effectiveness, piTBS may be an optimal form of rTMS in treating older adults with TRD. Further large comparative effectiveness trials with standard iTBS or high-frequency rTMS in this population are warranted.

The 8-Item Informant Interview to Differentiate Aging and Dementia (AD8) was developed as a screening tool for dementia with a cutoff of 2 suggested by the initial study. However, various studies found different cutoff values, and many found a cutoff of 2 might result in a high false positive rate. Furthermore, a higher false positive rate in Taiwan was repeatedly shown when AD8 was self-administered in local government screening programs. This study aimed to test the performance of AD8, define its best cutoff value, review factors that may affect its performance, and reconsider its proper role in clinical practice.

We recruited 118 participant-informant dyads from a university teaching hospital. For each informant, the AD8 was administered first and then the Clinical Dementia Rating to minimize contamination effect. For each participant, two geriatric psychiatrists considered history, physical and mental status examination, laboratory testing, neuropsychological testing, and neuroimaging results to make the final consensus diagnosis based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The receiver operator characteristic curve was used to assess the diagnostic performance of AD8.

There were 59 subjects with normal cognition, 28 with mild neurocognitive disorder, and 31 with major neurocognitive disorder or dementia. To discriminate between dementia and non- dementia, a cutoff of 2 resulted in a sensitivity of 0.903, specificity of 0.598, and area under the curve (AUC) of 0.751. Moving the cutoff to 3 and 4 led to better specificity (0.7126, 0.8621) and greater AUC (0.776, 0.818), albeit some loss in sensitivity (0.8387, 0.7742). The best cutoff score was 4 based on the Youden index. Without considering the mild cognitive impairment group, the optimal cutoff remained at 4, with equal sensitivity and even higher specificity.

Our findings suggest the AD8 may perform better and have a lower false positive rate with a cutoff value higher than 2. A literature review found its performance could be affected by disease prevalence across various healthcare settings, education level, regions, respondents’ personality and understanding of questions, conduct of test, flow of test administration, etc. We will discuss the details and best screening strategies at the IPA Congress.

The Min-Mental State Exam (MMSE) is the most common exam for screening and follow-up of cognitive impairment. One of 30 points is allocated to correct orientation to the weekday (“day orientation”).

The purpose of this study is to assess whether day orientation correlates with the weekday in which the exam was conducted, hypothesis being that orientation would be better on the work day immediately following the weekend (in Israel – Sundays).

All digitally recorded MMSE scores from Shalvata MHC’s were collected. The percentage of correct answers to day orientation was compared between weekdays. Differences between in/correct answers were assessed by Chi-square tests, with Cramer's V for the effect size of the correlations. Differences in total score between groups were assessed by independent t- tests with Cohen's d for effect size (p=0.05)

The cohort consisted of 2,049 MMSE taken by 1,376 patients [average age 80.3 (SD 9.3) 56.4% Female] between 2016 and 2022. Due to very few responses (n=7) on Friday and Saturday, these days were excluded from analyses. Overall, 67.8% of exams were correctly oriented to the day. Correct response rate according to the weekday yielded a significant result (X2 = 20.77, p < .001, Cramer's V = 0.104), with the largest effect difference was found on Sundays (53.4%), and then on Mondays (38.9%). The relative odds ratio (OR) for providing a correct response was found for Sunday (OR=1.55, p=.001), while for other days no significant OR was found. Patients who responded correctly showed higher final total scores in comparison with patients who did not respond correctly across all days. Similar analysis was carried out for orientation to the month, comparing between the first 5 days and last 5 days of the month, but no statistically significant difference for correct answers was found.

MMSE delivered on the first working day of the week may entail a better day orientation, and thus a higher total score. This finding may have significant implications for assessments (as in clinical trials) and thus treatment.

Most frequently felt needs in dementia concern maintaining self-management and participation in meaningful activities. E-health interventions may support these aspects of social health but few have undergone large-scale evaluations. The effectiveness of the FindMyApps intervention, an app selection tool and tablet training, designed to support people to find and use tablet apps that meet their needs and interests, was evaluated.

A non-blinded, single-centre, randomized controlled trial and process evaluation were conducted in the Netherlands between January 2020 and November 2022. Participants were community-dwelling people with mild dementia (MMSE <26 and >17) or mild cognitive impairment, and their informal caregivers. FindMyApps was compared with digital care as usual (normal tablet computer and general advice). Data regarding primary outcomes (self-management and social participation of the person with dementia, sense of competence of the caregiver) and secondary outcomes (including quality of life) were collected with standardized instruments at baseline and after a three months intervention period. ANCOVAs were conducted on post-test outcome measures, corrected for baseline scores, to investigate group differences.

Data collection was completed in November 2022 and analyses are underway. Of 150 dyads randomized, 128 completed the three-month follow-up (64 experimental, 64 control). Results of ANCOVAs investigating the effect and effect size of FindMyApps on the primary and secondary outcomes at three months, will be reported, as well as results of post-hoc analyses that explored the effect on outcomes of: previous tablet experience and education level of participants; observed use of the FindMyApps app; and reported adherence to recommended frequency of tablet use.

Results of this study will indicate whether FindMyApps is an effective intervention for supporting social health of people with mild dementia and MCI. Comparisons with previous studies of FindMyApps and other digital interventions for social health in dementia will be drawn and implications for professionals, concerning implementation of FindMyApps, and for researchers regarding further development, translation and evaluation of FindMyApps discussed. Finally, establishing feasibility and utility of randomized controlled trials in this field, the results of this study will set the bar for future evaluations of eHealth interventions in general.
