Background: despite rapid population ageing, few studies have investigated frailty in older people in sub-Saharan Africa. We tested a cumulative deficit frailty index in a population of older people from rural South Africa., Methods: analysis of cross-sectional data from the Health and Ageing in Africa: Longitudinal Studies of an INDEPTH Community (HAALSI) study. We used self-reported diagnoses, symptoms, activities of daily living, objective physiological indices and blood tests to calculate a 32-variable cumulative deficit frailty index. We fitted Cox proportional hazards models to test associations between frailty category and all-cause mortality. We tested the discriminant ability of the frailty index to predict one-year mortality alone and in addition to age and sex., Results: in total 3,989 participants were included in the analysis, mean age 61 years (standard deviation 13); 2,175 (54.5%) were women. The median frailty index was 0.13 (interquartile range 0.09-0.19); Using population-specific cutoffs, 557 (14.0%) had moderate frailty and 263 (6.6%) had severe frailty. All-cause mortality risk was related to frailty severity independent of age and sex (hazard ratio per 0.01 increase in frailty index: 1.06 [95% confidence interval 1.04-1.07]). The frailty index alone showed moderate discrimination for one-year mortality: c-statistic 0.68-0.76; combining the frailty index with age and sex improved performance (c-statistic 0.77-0.81)., Conclusion: frailty measured by cumulative deficits is common and predicts mortality in a rural population of older South Africans. The number of measures needed may limit utility in resource-poor settings., (© The Author(s) 2021. Published by Oxford University Press on behalf of the British Geriatrics Society.

Parkinson's disease is a chronic multi-system disease that can cause motor and non-motor symptoms, cognitive changes and variably effective medications. Optimal management of the condition requires a multi-disciplinary team of healthcare professionals to work closely with the patient and their carers. The National Institute for Health and Care Excellence published updated guidelines on managing Parkinson's disease in adults in 2017. Here we discuss the implications of this guidance to current healthcare professionals involved in the care of people with Parkinson's disease. The guidance highlights the importance of clear communication with people with Parkinson's disease. We discuss examples of this, including providing a point of contact with specialist services for people with Parkinson's disease and ensuring information about the risks of impulse control disorders are given to people on dopaminergic therapy. The breadth of services required by people with Parkinson's disease is also described, including the need for access to physiotherapy, occupational therapy and speech and language therapy as well as treatment monitoring services for Clozapine. In addition, we emphasise the continued importance of ensuring people with Parkinson's disease receive their medications on time when in hospital or a care home., (© The Author(s) 2018.

2017 marks 200 years since James Parkinson's published his 'Essay on the Shaking Palsy'. Although now most famous for describing the condition that came to bear his name, Parkinson had a wide range of interests and his influence spread beyond medicine. In this review, we provide a biography of James Parkinson's remarkable life.Parkinson's paper not only comprehensively described the symptoms of Parkinson's disease (PD), but challenged his peers to better understand the pathophysiology of the PD. Key observation over the next 2 centuries, included the recognition of the link between the substantia nigra and PD and the discoveries of dopamine deficiency in patients with PD. We review the subsequent development of pharmacological and surgical therapies. Despite great progress over the last 200 years, Parkinson's hopes for a 'cure if employed early enough' or that 'some remedial process may ere long be discovered by which at least the progression of the disease may be stopped' remain apposite today and we reflect on the challenges ahead for the next century.

Background: Low diagnostic rates are a barrier to improving care for the growing number of people with dementia in sub-Saharan Africa. Many people with dementia are thought to visit traditional healers (THs) and Christian faith healers (FHs) and these groups may have a role in identifying people with dementia. We aimed to explore the practice and attitudes of these healers regarding dementia in rural Tanzania and investigate attitudes of their patients and their patients’ carers., Methods: This was a qualitative study conducted in Hai district, Tanzania. Semi-structured interviews were conducted with a convenience sample of THs and FHs and a purposive-stratified sample of people with dementia and their carers. Interview guides were devised which included case vignettes. Transcripts of interviews were subject to thematic analysis., Findings: Eleven THs, 10 FHs, 18 people with dementia and 17 carers were recruited. Three themes emerged: (i) conceptualisation of dementia by healers as a normal part of the ageing process and no recognition of dementia as a specific condition; (ii) people with dementia and carer reasons for seeking help and experiences of treatment and the role of prayers, plants and witchcraft in diagnosis and treatment; (iii) willingness to collaborate with allopathic healthcare services. FHs and people with dementia expressed concerns about any collaboration with THs., Conclusions: Although THs and FHs do not appear to view dementia as a specific disease, they may provide a means of identifying people with dementia in this setting.

Background: we have previously conducted a community-based prevalence study of dementia in older adults living in the rural Hai district of Tanzania. The aim of this study was to record mortality rates at 4 years post-diagnosis, of those with dementia, mild cognitive impairment (MCI) and no cognitive impairment., Methods: during Phase I of the prevalence study, 1,198 people aged 70 years and over were screened, and a stratified sample of 296 was assessed for the presence of dementia or MCI in Phase II. Seventy-eight people had dementia and 46 had MCI. Four years after diagnosis, we attempted to follow-up all those seen in Phase II and record all deaths., Results: of the 296, follow-up data were available for 287 (97.0%), including 77 with dementia and 45 with MCI. Of the 172 with no cognitive impairment, 165 (95.9%) were followed up and a sample of 89 people selected as representative of the background population. Forty-eight people with dementia (62.3%), 19 with MCI (42.2%) and 11 with no cognitive impairment (12.4%) had died at 4-year follow-up. After adjusting for the effects of age, gender and education, the hazard ratio was 6.33 (95% CI 3.19-12.58) for dementia and 3.57 (95% CI 1.64-7.79) for MCI relative to people with no cognitive impairment. Mortality rates were highest in those with vascular dementia., Conclusion: dementia and MCI were associated with excess mortality relative to those with no cognitive impairment., (© The Author 2015.

Background: simulation-based teaching is increasingly used in medical education, but no studies have evaluated its impact on learning in geriatric medicine. We developed and delivered a simulation teaching session on delirium, falls, elder abuse and breaking bad news. Simulation mannequins, professional role-players and simulated clinical documentation were all incorporated into scenarios. We evaluated the effect of this intervention on student learning and on students' attitudes towards geriatric medicine., Methods: third year Newcastle University MBBS students at Northumbria base unit received the simulation-based teaching session. Students' knowledge was assessed using a three question test mapped to learning outcomes for the elder abuse, delirium and falls stations. Each student undertook the test on three occasions: the day before the teaching session, immediately after the session and ∼1 month later, allowing evaluation of learning over time. Test scores were also compared with those achieved by another cohort of third year MBBS students at a different base unit, who received traditional ward-based and didactic teaching but no simulation teaching., Results: student knowledge improved significantly after the simulation session and this was maintained when reassessed a month later. Students who received the simulation-based training outperformed those who received usual teaching. Student feedback was overwhelmingly positive and the vast majority of students agreed that the session had a positive impact on their perceptions of geriatric medicine., Discussion: our findings demonstrate the efficacy of simulation-based teaching in undergraduate geriatric medicine, its acceptability to students and its positive influence on students' perceptions of the specialty.

Background: the population is ageing globally and developing countries are experiencing the most rapid increase in the number of older persons. By 2045 the United Nations estimate that for the first time in history more people will be over 65, than under 15, years of age. The World Health Organization predicts that deaths from non-communicable diseases will rise by 24% in Africa in the next decade. The aim of this survey was to determine the specialist medical services available for older persons and the undergraduate and postgraduate training systems in place for geriatrics in each African country., Methods: a short survey was developed and sent to representatives from every country. Where appropriate, French and Portuguese translations were available., Results: responses were received from 40/54 countries (74%). Data were obtained via an internet search for a further three countries. Out of 43, 25 countries had no geriatricians. Out of 40, 35 countries had no formal undergraduate training for medical students on geriatrics and 33 of 40 countries reported no national postgraduate training scheme for geriatrics. Having at least one geriatrician in the country was associated with a World Bank upper middle-income status (P = 0.04), but there was no significant association with the population size (P = 0.395)., Conclusion: despite increasing numbers of older people and the increasing burden of chronic disease there are few geriatricians in Africa. Without undergraduate training, even general medical physicians will have limited knowledge of specialist geriatric needs. This is an area that will require development and investment in the future.

Background: the World Health Organization estimates that more than one billion of the world's population are disabled. Disability is associated with increasing age and poverty, yet there are few reliable data regarding disability among the elderly in low-income countries. The aim of this study was to accurately document the prevalence of disability in those aged 70 years and over in a community-based setting in sub-Saharan Africa., Methods: we performed a community-based study of people aged 70 years and over in Hai, Tanzania. Participants underwent disability assessment using the culturally non-specific Barthel index (BI), and also clinical assessment for neurological disorders and memory problems., Results: in 2,232 participants, the age-adjusted prevalence of severe disability (BI<15) was 3.7% (95% CI: 2.9-4.5) and the age-adjusted prevalence of moderate disability (BI: 15-18) was 6.2% [95% confidence interval (CI): 5.2-7.2]. Increasing age, female gender, memory problems and the presence of neurological disorders were all independent predictors of the presence of disability., Conclusion: in this study, the average disability level was lower than seen in most high-income countries. This may reflect increased mortality from disabling disease in low-income countries. Disability is likely to increase as the population of low-income countries ages and disease survival improves.

Background: Parkinson's disease (PD) is the second most common neurodegenerative condition in the UK. Care needs increase as the disease progresses, but there are very few published data in relation to this., Objective: the aim of this study was to elicit the care requirements for a prevalent PD population and compare these to a similarly aged background population., Methods: all people diagnosed with idiopathic PD from within a defined area of north-east England were asked to participate in this study. Those who agreed to participate were assessed using a number of standard rating scales including Hoehn and Yahr stage, Unified Parkinson's Disease Rating Scale (UPDRS), Hospital Anxiety and Depression Scale, Parkinson's Disease Questionaire-39 and Mini-Mental State Examination (MMSE). In addition, participants were asked whether they had experienced hallucinations. Social and demographic information (e.g. age, sex and place of abode) was also recorded., Results: from all cases (n = 161), 135 people (83.8%) agreed to participate. Of these, 19 (14.1%) were living in residential or nursing homes, representing 1.6% of the total nursing/residential home residents in the study area. Participants had a mean age of 74.8 years and disease duration of 5.6 years. Those in care were significantly older and had significantly poorer Hoehn and Yahr, MMSE and UPDRS scores., Conclusion: PD patients in institutional care have poorer cognitive function, are older, have later stage disease and worse functional ability than those living at home.

Parkinson's disease (PD) is said to be less common in Africa than elsewhere in the world, but previous studies have been based on small numbers. Also, the differences may be due to the diagnostic criteria used, case finding methods and different population age structures. Developing countries have few facilities for chronic disease management and non-communicable diseases, although on the increase, tend to play second fiddle to malaria and HIV/AIDS. Previous reports suggest that, at least from anecdotal information, under-diagnosis of PD is common and long-term availability of medication, follow-up, patient education and multidisciplinary input is lacking. Published literature is scarce and there is a lack of recent information. We are currently conducting a door-to-door prevalence study in northern Tanzania in a population of 161,162. We have reviewed previous literature on PD in Africa and illustrate our personal experience of PD and its management in Africa with three cases.

Background: cognitive decline is well recognised in Parkinson's disease (PD) but the best cognitive assessment tool for use in such patients remains unclear. The 30-point Mini-Mental State Examination (MMSE), while quick and straightforward to use, fails to cover a full range of cognitive domains and is recognised to have a ceiling effect. The Cambridge Cognitive Assessment-Revised (CAMCOG-R) is a cognitive screening tool allowing the assessment of a number of different domains of cognition. It has not previously been used specifically on PD subjects., Methods: a prevalent community population of 135 PD patients were assessed cognitively using the MMSE. Those scoring 25 or above on the MMSE were subsequently further assessed using CAMCOG-R. Demographic and disease factors including disease duration, symptom severity, anxiety, depression and the presence of hallucinations were recorded for each participant., Results: 31/135 (23%) demonstrated cognitive impairment on the MMSE (score < 25). Ninety-four of the remaining group (10 were excluded) achieved a median total CAMCOG-R score of 89/104. The results were widely distributed. The subjects scored particularly highly in the cognitive domains of orientation, comprehension and perception but relatively poorly at memory and abstract thinking. Significantly poorer scores (P < 0.05) were seen throughout the cognitive domains with increasing age, increasing PD symptom severity and increasing disease duration, but not with the presence of anxiety, depression or hallucinations in the subjects., Discussion: CAMCOG-R was found to be a viable and useful cognitive screening tool for use in PD. A wide range of cognitive ability was demonstrated in subjects who had been assessed previously by the MMSE as not having significant cognitive impairment. The group performed worse in certain cognitive domains than others and those who were older, with more severe PD symptoms and with symptoms for longer, scored less well.
