Participatory development of a home-based depression care model with lived experience older Nigerians and their caregivers: A theory of change.

OBJECTIVES: There is a huge treatment gap for late-life depression in sub-Saharan Africa. Building on prior work to scale-up mental healthcare with the aid of the WHO Mental Health Gap Action Programme Intervention Guide electronic version (emhGAP-IG), this study aims to involve older people in the iterative development of innovations to overcome challenges in the detection and clinical management of late-life depression by frontline non-specialist primary healthcare workers (PHCW) in Nigeria. METHODS: There were 43 participants in the study. We conducted formative qualitative research using 15 in-depth key informant interviews with persons who were 60 years or older and had a recent experience of depression. We also conducted two focus group discussions comprising 13 of their caregivers. Through a full day stakeholders workshop comprising 15 participants, we drew on the results of our qualitative explorations to identify the pathway to impact of an intervention package (emhGAP-Age) appropriate for the specific needs of persons with late-life depression in Nigeria. RESULTS: A Theory of Change (ToC) map was produced. It highlights the expected long-term outcomes of emhGAP-Age to include the potential for improvement of the mental health and wellbeing of older people living in Nigeria and the generation of interest among governmental agencies concerned with policy and planning for mental healthcare. Key resources that serve as preconditions were identified to consist of the availability of PHCW who are skilled in the identification and treatment of depression and have interest in and commitment to providing care to older people. Required community resources include support from immediate family, neighbours, and informal groups. Interventions that are appropriate for depression in old age need to incorporate these community resources and address not only the symptoms of the condition but also comorbid physical health problems. CONCLUSIONS: A participatory ToC process led to the identification of the key components of an age-appropriate version of the emhGAP-IG for delivering care to older persons with depression by PHCW in Nigeria.

Physical restraint in older people: a statement from the Early Career Network of the International Psychogeriatric Association.

The International Psychogeriatric Association (IPA) has expressed significant concerns over the use of physical restraints in older people across diverse aged care settings. Following an extensive analysis of the available literature, the IPA's Early Career Network (ECN) has formulated a collection of evidence-based recommendations aimed at guiding the use of physical restraints within various care contexts and demographic groups. Physical restraints not only infringe upon human rights but also raise significant safety concerns that adversely impact the physical, psychological, social, and functional well-being of older adults. Furthermore, their effectiveness in geriatric settings remains inadequate. Given these considerations, the IPA and its ECN firmly assert that the use of physical restraints should only be considered as a final recourse in the care of older people.

New living evidence resource of human and non-human studies for early intervention and research prioritisation in anxiety, depression and psychosis.

In anxiety, depression and psychosis, there has been frustratingly slow progress in developing novel therapies that make a substantial difference in practice, as well as in predicting which treatments will work for whom and in what contexts. To intervene early in the process and deliver optimal care to patients, we need to understand the underlying mechanisms of mental health conditions, develop safe and effective interventions that target these mechanisms, and improve our capabilities in timely diagnosis and reliable prediction of symptom trajectories. Better synthesis of existing evidence is one way to reduce waste and improve efficiency in research towards these ends. Living systematic reviews produce rigorous, up-to-date and informative evidence summaries that are particularly important where research is emerging rapidly, current evidence is uncertain and new findings might change policy or practice. Global Alliance for Living Evidence on aNxiety, depressiOn and pSychosis (GALENOS) aims to tackle the challenges of mental health science research by cataloguing and evaluating the full spectrum of relevant scientific research including both human and preclinical studies. GALENOS will also allow the mental health community-including patients, carers, clinicians, researchers and funders-to better identify the research questions that most urgently need to be answered. By creating open-access datasets and outputs in a state-of-the-art online resource, GALENOS will help identify promising signals early in the research process. This will accelerate translation from discovery science into effective new interventions for anxiety, depression and psychosis, ready to be translated in clinical practice across the world.

Mild anxiety and depression disorders: Unusual reactions to COVID-19 lockdown in caregivers of older adults attending a psychogeriatric clinic in Southwest Nigeria.

BACKGROUND: Many sub-Saharan African countries have fragile healthcare systems and the mental health care of older adults is in a precarious state. The lockdown that accompanied COVID-19 infection was another monumental event. OBJECTIVE: This study examined the effect of the restriction and lockdown on the mental health of the caregivers of older patients attending a psychogeriatric clinic in Ibadan, Nigeria. MATERIALS AND METHODS: We selected 178 dyads of patients and their caregivers. These caregivers were administered a semi-structured questionnaire that collected demographic information and asked questions on effect of COVID-19 on caregiving. In addition, Patient Health Questionnaire-9 and generalised anxiety disorder-7 item scale were administered. Participants were interviewed through telephone. RESULTS: One hundred and seventy-eight patients' caregivers' dyads were interviewed. About 62.4% of the caregivers were children of the patients. More importantly, 97.2% and 93.8% had neither depressive nor anxiety symptoms and the caregivers expressed little worry about COVID-19. There was no significant difference in the mean depressive and anxiety scores in caregivers of patients with and without dementia (F = 0.28, P = 0.60). Caregivers who were lesser than 50 years in age had significantly higher mean score compared with those who were 50 years and above (F = 5.54, P = 0.03). CONCLUSION: The rate of anxiety and depressive symptoms was very low in this cohort as the lockdown during the pandemic produced little distress to caregivers including those caring for patients with dementia and cognitive impairment. This is a deviation from reports of some other countries and cultures which described psychological implications of COVID-19 on caregivers as severe.

Cross-national harmonization of cognitive measures across HRS HCAP (USA) and LASI-DAD (India).

BACKGROUND: As global populations age, cross-national comparisons of cognitive health and dementia risk are increasingly valuable. It remains unclear, however, whether country-level differences in cognitive function are attributable to population differences or bias due to incommensurate measurement. To demonstrate an effective method for cross-national comparison studies, we aimed to statistically harmonize measures of episodic memory and language function across two population-based cohorts of older adults in the United States (HRS HCAP) and India (LASI-DAD). METHODS: Data for 3,496 HRS HCAP (≥65 years) and 3,152 LASI-DAD (≥60 years) participants were statistically harmonized for episodic memory and language performance using confirmatory factor analysis (CFA) methods. Episodic memory and language factor variables were investigated for differential item functioning (DIF) and precision. RESULTS: CFA models estimating episodic memory and language domains based on a priori adjudication of comparable items fit the data well. DIF analyses revealed that four out of ten episodic memory items and five out of twelve language items measured the underlying construct comparably across samples. DIF-modified episodic memory and language factor scores showed comparable patterns of precision across the range of the latent trait for each sample. CONCLUSIONS: Harmonization of cognitive measures will facilitate future investigation of cross-national differences in cognitive performance and differential effects of risk factors, policies, and treatments, reducing study-level measurement and administrative influences. As international aging studies become more widely available, advanced statistical methods such as those described in this study will become increasingly central to making universal generalizations and drawing valid conclusions about cognitive aging of the global population.

Different Cognitive and Functional Outcomes in Attenuated and Full Delirium Syndromes Among Recent Stroke Survivors.

BACKGROUND: Very little is known about the outcomes of poststroke delirium in relation to its symptom spectrum. We investigated the 3-months cognitive and functional outcomes of attenuated (ADS) and full delirium syndromes in Nigerian survivors of first ever stroke. METHODS: A prospective observational study with repeated assessments conducted in the first week of stroke using the confusion assessment method. Full delirium was diagnosed according to criteria in the fifth edition of the diagnostic and statistical manual of mental disorders (DSM-V). ADS was characterised in survivors who were free of full, but had ≥two core features of, delirium. Baseline and follow-up assessments were conducted using the Mini-Mental state examination (MMSE), 10-words list learning and delayed recall test, Animal naming test and Barthel index. RESULTS: Among 150 participants, ADS was present in 32 (21.3%), full delirium in 29 (19.3%). In linear regression analyses adjusting for age, economic status and systemic hypertension, ADS [(Mean difference (MD) = -3.8, 95% C.I = -7.0, -0.7)] and full delirium (MD = -5.6, 95% C.I = -9.0, -2.1) independently predicted poorer global cognitive functioning at follow-up. Significant declines in memory (MD = -1.9, 95% C.I = -2.8, 0.9), executive (MD = -2.2, 95% C.I = -4.1, -0.3) and physical functioning (MD = -2.8, 95% C.I = -5.5, -0.2), as well as a 4-fold increase in the independent odds (O.R) for dementia (O.R = 4.1, 95% C.I = 1.0,16.1) were also recorded in full, but not attenuated, delirium. CONCLUSION: Attenuated and full delirium are associated with graded risk of poststroke cognitive decline. Reconsideration of poststroke delirium as a spectrum, rather than threshold-based categorical diagnosis will improve detection and prioritization of stroke survivors at increased risk of cognitive decline.
