I address this question using ethnographic fieldwork, interviews and document analysis conducted between September 2010 and March 2014, which examine the relations involved in the emergence of a national dementia research agenda in the UK. Over the last decade in the UK ‘dementia’ has become characterised as the public health crisis of our time. The sense of crisis around the conditions covered by this umbrella term is exacerbated by a global trend toward increased longevity and acute awareness of the limitations of existing treatments. In 2011 the UK Department of Health, in collaboration with national research organisations, announced the launch of an integrated dementia research strategy. Taking a historical and emergent perspective on research into aging, neurodegenerative diseases and the concept of ‘dementia’, this examination demonstrates how the evolving research initiative marks a shift in the process of co-production which exists between science, policy and publics in the UK. Using a detailed examination of linguistic and visual material from the perspective of science policy and practice, the thesis demonstrates how shifts in biotechnology make conditions described under the umbrella of ‘dementias’ differently visible. The scientific narratives which accompany this changing visibility, present dementias as a challenging target for social and scientific intervention. In response to this complexity, the research agenda focuses on the relationships and interactions between the multiple stakeholders involved. A rhetoric-based analysis demonstrates how researchers use such collaborations to try and remake the connections between aging, dementia, science and social responsibility. I argue that this process of breaking and remaking such connections is part of persuasive attempt to embed patients, participants and publics in the conduct of clinical research. This ethnographic description demonstrates how this process of embedded engagement is not without challenge. Researchers feel increasingly exposed to public expectations and frustrations which exist beyond the control of the ‘citadel’ of science (Martin 1998). Thus through cyclical re-workings of narratives of success and failure, hope and possibility, researchers involved in the development of new interventions for dementia diagnosis and treatment attempt to balance the tension between the rhetoric of future potential products and their day-to-day experience of the scientific process. Thus the thesis demonstrates how the development of new interventions is a continual negotiation of uncertainties and anxieties for both researchers and their participants. The thesis contributes to a growing literature on the complexity of biomedical research and knowledge making. 1 Collaborations, Connections and Participation: An ethnographic study of dementia research in the UK Sally A.

  • Evidence of Sustained Benefits of Pimavanserin for Dementia-Related Psychosis 22 July 2021
    Evidence of sustained benefits of pimavanserin for dementia-related psychosis 22 July 2021 Journal of Medicine outlines a clinical trial, conducted in 392 people with psychosis associated with Alzheimer's disease, Parkinson's disease, Lewy body, frontotemporal, or vascular dementia. All participants were given pimavanserin for 12 weeks. Those who met a threshold of symptom improvement were then assigned to pimavanserin or placebo for up to 26 weeks. The trial was stopped early for positive efficacy results. Of the 351 participants, 217 (61.8%) had a sustained initial treatment benefit, of whom 112 were assigned to placebo and 105 to pimavanserin. Relapse occurred in 28/99 (28.3%) of the placebo Credit: CC0 Public Domain group, compared to 12/95 (12.6%) of the pimvanserin group, with pimvanserin more than halving the relapse rate and significantly improving the sustained benefit.

It has been designed to be a practical, informative tool, with an emphasis on alternatives to drug treatment. These best practice principles and supporting materials are intended to be applicable to all professional groups, except in acute general hospital settings. We hope they will be helpful to practitioners in environments where this aspect of clinical practice will increasingly come under scrutiny.

Background In 2011, The Office of the Inspector General (OIG) of the Department of Health and Human Services released a report underscoring the high use of atypical antipsychotic medications for “off-label” indications among nursing home residents. According to this report, 83% of atypical antipsychotic drug claims were for elderly nursing home residents who had not been diagnosed with a condition for which antipsychotic medications were approved by the FDA.1 Nursing home advocates and others expressed concern for the high rates of antipsychotic medication use and urged CMS to do more to address this persistent threat to quality and safety. In early 2012, in response to the OIG report, as well as concerns from advocates and commitment from provider associations and other stakeholders, CMS established the National Partnership to Improve Dementia Care in Nursing Homes. National Partnership The National Partnership seeks to optimize quality of life for residents in America’s nursing homes by improving comprehensive approaches to the psychosocial and behavioral health needs 1 Levinson DR.
