Overview

Professor Louise Allan moved to the University of Exeter as Professor of Geriatric Medicine in June 2018. She has a specialist interest in the Neurology and Psychiatry of Old Age and is a member of the Centre for Research in Ageing and Cognitive Health (REACH), which is a joint venture between the School of Psychology, the University of Exeter Medical School and PenCLAHRC.

Current research themes focus on falls and physical health care in dementia, the effects of delirium upon cognitive decline, and non-Alzheimer’s dementias including post-stroke dementia and Lewy body disease.

Louise completed undergraduate studies at Oxford University and then did house jobs in Oxford and Whitehaven, after which she moved to Newcastle to complete higher medical training as a Geriatrician. She had an Alzheimer’s Society Fellowship for the completion of her doctoral studies on autonomic dysfunction in dementia and then she became a lecturer at Newcastle University (2007-2008) and subsequently a senior lecturer (2008-2018). Clinically, Louise will be working as a Geriatrician in the memory clinic at the Royal Devon and Exeter Hospital.

Research

Research interests

Louise’s research focusses on three themes: Physical health in dementia and Delirium, Vascular Cognitive Impairment and Lewy Body disease.

1. Physical health in dementia

She has previously published work on the risk factors for falls in people with dementia, and is currently leading an NIHR funded Health Technology Assessment Programme to investigate whether it is possible to design a complex intervention to improve the outcome of fall related injuries in dementia (https://research.ncl.ac.uk/difrid/ ).

During her research into dementia delirium has emerged as a significant theme which needs further investigation. The DECIDE study is examining the role of delirium as a potential cause of and exacerbating factor for dementia in a prospective study which we are now undertaking with the CFAS II cohort.

2. Vascular Cognitive Impairment

This work includes the long term follow up of the MRC funded COGFAST cohort, one of the world’s largest and longest running clinicopathological cohort studies of people with cerebrovascular disease. We have reported on the long term incidence and neuropathological features of dementia and depression after stroke, and in particular identified that delayed dementia after stroke is primarily associated with predominantly vascular rather than mixed pathology.

We have also established a Nigerian cohort (COGFAST-Nigeria), which will enable comparisons of Vascular Cognitive Impairment between developed and developing countries, the latter being an increasingly important setting for dementia research due to the expanding and ageing demographics in the developing world.

3. Lewy Body disease

The investigation of Lewy Body disorders is an important focus of research for the DEMANDS group and we host an NIHR Biomedical Research Unit in Lewy Body disease. She is a co-investigator in the DIAMOND-Lewy study, an NIHR funded programme grant which aims to improve the diagnosis and management of Lewy body disorders including Dementia with Lewy bodies and Parkinson’s disease dementia (https://research.ncl.ac.uk/diamondlewy/).

She has an interest in autonomic dysfunction in dementia, and previous work in the MRC funded Lewy Body Disease cohort study has shown that autonomic dysfunction is a particularly common feature of the Lewy body dementias and an important risk factor for falls.

Robalino S, Nyakang'o SB, Beyer FR, Fox C, Allan LM (In Press). Effectiveness of interventions aimed at improving physical and psychological outcomes of fall-related injuries in people with dementia: a narrative systematic review. Syst Rev, 7(1).

BACKGROUND: the annual prevalence of falls in people with dementia ranges from 47 to 90%. Falls are a common reason for hospital admission in people with dementia, and there is limited research evidence regarding the care pathways experienced by this population. In addition to immediate management of an injury, prevention of further falls is likely to be an important part of any successful intervention. This review aims to assess the effectiveness of interventions for improving the physical and psychological wellbeing of people with dementia who have sustained a fall-related injury. METHODS: Systematic review methodologies were employed utilising searches across multiple databases (MEDLINE, CENTRAL, Health Management Information Consortium, EMBASE, CINAHL, Web of Science, Allied and Complementary Medicine Database, and Physiotherapy Evidence Database (PEDro)) and citation chaining. Studies including people with a known diagnosis of dementia living in the community and who present at health services with a fall, with or without injury, were included. Outcomes of interest included mobility, recurrent falls, activities of daily living, length of hospital stay, and post-discharge residence. Results were independently reviewed and quality assessed by two researchers, and data extracted using a customised form. A narrative synthesis was performed due to heterogeneity of the included studies. RESULTS: Seven studies were included. Interventions clustered into three broad categories: multidisciplinary in-hospital post-surgical geriatric assessment; pharmaceuticals; and multifactorial assessment. Multidisciplinary care and early mobilisation showed short-term improvements for some outcomes. Only an annual administration of zoledronic acid showed long-term reduction in recurrent falls. CONCLUSIONS: Due to high heterogeneity across the studies, definitive conclusions could not be reached. Most post-fall interventions were not aimed at patients with dementia and have shown little efficacy regardless of cognitive status. Minor improvements to some quality of life indicators were shown, but these were generally not statistically significant. Conclusions were also limited due to most studies addressing hip fracture; the interventions provided for this type of injury may not be suitable for other types of fractures or soft tissue injuries, or for use in primary care.

Background: People with dementia (PWD) experience ten times as many incident falls as people without dementia. Little is known about how best to deliver services to people with dementia following a fall. We used an integrated, mixed-methods approach to develop a new intervention which combines theory generated via a realist synthesis and data on current provision and pathways, gathered through a prospective observational study as well as qualitative interviews, focus groups and ethnographic observation. This intervention is to be tested in a feasibility study in the UK National Health Service. Methods: People living with dementia in one of three geographical areas will be eligible for the study if they experience a fall requiring healthcare attention and have an informal carer. Potential participants will be identified by community services (primary care, paramedics, telecare), secondary care (ED, facilitated discharge services, rehabilitation outreach teams) and research case registers. Participants will receive a complex multidisciplinary intervention focused on their goals and interests for up to 12 weeks. The intervention will be delivered by occupational therapists, physiotherapists and rehabilitation support workers. Feasibility outcomes will include recruitment and retention, suitability and acceptability of outcome measures and acceptability, feasibility and fidelity of intervention components. PWD outcome measures will include number of falls, Montreal Cognitive Assessment (MOCA), European Quality of Life Instrument (EQ-5D-5L), Quality of Life-Alzheimer's Disease Scale (QOL-AD), Modified Falls Efficacy Scale (MFES) and Goal Attainment Scaling (GAS). PWD outcome measures completed by an informal carer will include Disability Assessment for Dementia (DAD), EQ-5D-5L Proxy, QoL-AD Proxy and a Health Utilisation Questionnaire (HUQ). The carer outcome measure will be the Zarit Burden Interview (ZBI). An embedded process evaluation will explore barriers and facilitators to recruitment and intervention delivery. Discussion: the study results will inform whether and how a larger multicentre RCT should be undertaken. A full RCT would have the potential to show how outcomes can be improved for people with dementia who have fallen. Ethics and dissemination: the National Research Ethics Service Committee Newcastle and North Tyneside 2 approved the feasibility study. Trial registration: International Standard Randomised Controlled Trial Registry. Registration number: ISRCTN41760734. Date of registration: 16/11/2015.

PLAIN ENGLISH SUMMARY: Why did we do this study? it can be difficult for scientists to communicate their research findings to the public. This is partly due to the complexity of translating scientific language into words that the public understand. Further, it may be hard for the public to find out about and locate information about research studies. We aimed to adapt some scientific articles about the links between dementia and stroke into lay summaries to be displayed online for the general public. How did we do it? We collaborated with five people from a volunteer organisation, VOICENorth. They took part in two group discussions about studies reporting on the link between dementia and stroke, and selected four studies to translate into lay summaries and display on a website. We discussed the layout and language of the summaries and made adaptations to make them more understandable to the general public. What did we find? We were able to work with members of the public to translate research findings into lay summaries suitable for a general audience. We made changes to language and layout including the use of 'question and answer' style layouts, the addition of a reference list of scientific terms, and removing certain words. What does this mean? Working with members of the public is a realistic way to create resources that improve the accessibility of research findings to the wider public. ABSTRACT: Background Scientific research is often poorly understood by the general public and difficult for them to access. This presents a major barrier to disseminating and translating research findings. Stroke and dementia are both major public health issues, and research has shown lifestyle measures help to prevent them. This project aimed to select a series of studies from the Newcastle Cognitive Function after Stroke cohort (COGFAST) and create lay summaries comprehensible and accessible to the public. Methods We used a focus group format to collaborate with five members of the public to review COGFAST studies, prioritise those of most interest to the wider public, and modify the language and layout of the selected lay summaries. Focus groups were audio-taped and the team used the data to make iterative amendments, as suggested by members of the public, to the summaries and to a research website. We calculated the Flesch reading ease and Flesch-Kincaid grade level for each summary before and after the changes were made. Results in total, we worked with five members of the public in two focus groups to examine draft lay summaries, created by researchers, relating to eight COGFAST studies. Members of the public prioritised four COGFAST lay summaries according to the importance of the topic to the general public. We made a series of revisions to the summaries including the use of 'question and answer' style layouts, the addition of a glossary, and the exclusion of scientific jargon. Group discussion highlighted that lay summaries should be engaging, concise and comprehensible. We incorporated suggestions from members of the public into the design of a study website to display the summaries. The application of existing quantitative tools to estimate readability resulted in an apparently paradoxical increase in complexity of the lay summaries following the changes made. Conclusion This study supports previous literature demonstrating challenges in creating generic guidelines for researchers to create lay summaries. Existing quantitative metrics to assess readability may be inappropriate for assessing scientific lay summaries. We have shown it is feasible and successful to involve members of the public to create lay summaries to communicate the findings of complex scientific research. Trial registration Not applicable to the lay summary project.
