Pathways to care for people with dementia: An international multicentre study.

OBJECTIVE: The aim of the present study was to characterize the clinical pathways that people with dementia (PwD) in different countries follow to reach specialized dementia care. METHODS: We recruited 548 consecutive clinical attendees with a standardized diagnosis of dementia, in 19 specialized public centres for dementia care in 15 countries. The WHO "encounter form," a standardized schedule that enables data concerning basic socio-demographic, clinical, and pathways data to be gathered, was completed for each participant. RESULTS: The median time from the appearance of the first symptoms to the first contact with specialist dementia care was 56 weeks. The primary point of access to care was the general practitioners (55.8%). Psychiatrists, geriatricians, and neurologists represented the most important second point of access. In about a third of cases, PwD were prescribed psychotropic drugs (mostly antidepressants and tranquillizers). Psychosocial interventions (such as psychological counselling, psychotherapy, and practical advice) were delivered in less than 3% of situations. The analyses of the "pathways diagram" revealed that the path of PwD to receiving care is complex and diverse across countries and that there are important barriers to clinical care. CONCLUSIONS: The study of pathways followed by PwD to reach specialized care has implications for the subsequent course and the outcome of dementia. Insights into local differences in the clinical presentations and the implementation of currently available dementia care are essential to develop more tailored strategies for these patients, locally, nationally, and internationally.

The natural history of dementia.

This review summarizes studies on the natural history of dementia with a focus on Alzheimer's disease and vascular dementia. Understanding the course of dementia is important not only for patients, caregivers, and health professionals, but also for health policy-makers, who have to plan for national resources needed in the management of an increasing number of dementia cases. From the available published data, the life expectancy of elderly people with dementia is shorter than that of non-demented elderly. Reports on survival after a diagnosis of dementia vary from 3 to 12 years. The wide variation is partly due to the diagnostic criteria used in the studies and the sites where they were conducted (i.e. hospitals, clinics, or homes). There is an apparent difference in survival between Alzheimer's disease patients with onset of illness before 75 years and those after 75 years: the younger patients have a longer life expectancy. However, there are conflicting data on survival (in years) comparing male and female patients and comparing patients of different ethnicities. For vascular dementia, published papers on life expectancy vary between 3 to 5 years. Vascular dementia appears to have a poorer prognosis than Alzheimer's disease. The stages of severity of dementia were compared in a follow-up of a sample of Alzheimer's disease patients in Singapore, and the mean duration of the mild phase (clinical dementia rating 1) was 5.6 years, the moderate phase (clinical dementia rating 2) was 3.5 years, and the severe phase (clinical dementia rating 3) was 3.2 years. At the various phases of the disease, the demand on health-care services and economic cost are different.

Motoric cognitive risk syndrome, physio-cognitive decline syndrome, cognitive frailty and reversibility with dual-task exercise.

INTRODUCTION: Cognitive frailty (CF) is associated with dementia and disability. It was initially proposed in 2013 by the International Institute of Nutrition and Aging and the International Geriatrics Association. Over the years, there have been many emerging definitions e.g., Motoric Cognitive Risk Syndrome (MCR), Physio-cognitive Decline Syndrome (PCDS), reversible CF and potentially reversible CF. OBJECTIVE: Our objective was to determine the demographics including physical, functional, and psychosocial factors for the four CF definitions amongst community-dwelling older adults. In addition, the effect of dual-task exercise on the reversibility of different definitions of CF was also studied. METHODS: Participants were community-dwelling older adults aged ≥60 years recruited between August 2017 and December 2019. Older adults screened to be frail, prefrail or have cognitive impairment were invited to participate in dual-task exercise program called HAPPY (Healthy Ageing Promotion Program for You). Improvement in cognition, frailty, and physical performance after a 3-month dual-task exercise intervention program was compared with controls. RESULTS: The prevalence of CF depending on definition ranged from 8.8% to 28.7% with minimal overlap. The cognitive scores were significantly lower in all the groups predominantly affecting non-memory domains except for reversible CF. Frailty was three to seven times more prevalent in CF. MCR group had higher prevalence of functional limitation, pain and depression. All four groups had significant increase in global cognition scores especially in the attention domain where the control group declined, and reduction in the prevalence of frailty post intervention. MCR and reversible CF were significantly associated with increased odds of cognitive improvement after 3 months of intervention compared with control. CONCLUSION: CF is a novel concept and regardless of the definitions, is a target for reversing frailty, functional limitation and cognitive impairment through dual-task exercise. Long-term prospective studies are needed to evaluate the effectiveness of dual-task interventions in delaying the conversion to dementia and reduction of disability.

Optimizing stroke systems of care by enhancing transitions across care environments.

Stroke affects many aspects of the lives of stroke survivors and their family caregivers. Supporting long-term recovery and rehabilitation are necessary to help stroke survivors adapt to living with the effects of stroke and to help family members adapt to the caregiving role. During recovery and rehabilitation, many elements of the health care continuum are utilized, including emergency response, acute care, inpatient and outpatient rehabilitation, and community and long-term care. With the advent of thrombolytic therapy and the benefits of stroke units, stroke survival and outcomes are improving. As a result, the current emphasis of stroke system improvement is to implement stroke units throughout the developed world. To enhance the patient centeredness of stroke care delivery, an important next phase of stroke system improvement will center on the experiences of stroke survivors and their family caregivers as they move through diverse care environments. The objective of this article was to conduct a scoping review of the literature on stroke transitions to identify the current areas of research emphasis. This article highlights stroke survivors' and family caregivers' experiences with transitions across care environment and some potential strategies to improve those transitions.
