Abstract: The British Association for Psychopharmacology (BAP) coordinated a meeting of experts to review the evidence on the drug treatment for dementia. The level of evidence (types) was rated using a standard system: Types 1a and 1b (evidence from meta-analysis of randomised controlled trials or at least one controlled trial respectively); types 2a and 2b (one well-designed study or one other type of quasi experimental study respectively); type 3 (non-experimental descriptive studies); and type 4 (expert opinion). There is type 1a evidence for cholinesterase inhibitors (donepezil, rivastigmine and galantamine) for mild to moderate Alzheimer's disease; memantine for moderate to severe Alzheimer's disease; and for the use of bright light therapy and aromatherapy. There is type 1a evidence of no effect of anti inflammatory drugs or statins. There is conflicting evidence regarding oestrogens, with type 2a evidence of a protective effect of oestrogens but 1b evidence of a harmful effect. Type 1a evidence for any effect of B12 and folate will be forthcoming when current trials report. There is type 1b evidence for gingko biloba in producing a modest benefit of cognitive function; cholinesterase inhibitors for the treatment of people with Lewy body disease (particularly neuropsychiatric symptoms); cholinesterase inhibitors and memantine in treatment cognitive impairment associated with vascular dementia; and the effect of metal collating agents (although these should not be prescribed until more data on safety and efficacy are available). There is type 1b evidence to show that neither cholinesterase inhibitors nor vitamin E reduce the risk of developing Alzheimer's disease in people with mild cognitive impairment; and there is no evidence that there is any intervention that can prevent the onset of dementia. There is type 1b evidence for the beneficial effects of adding memantine to cholinesterase inhibitors, and type 2b evidence of positive switching outcomes from one cholinesterase inhibitor to another. There is type 2a evidence for a positive effect of reminiscence therapy, and type 2a evidence that cognitive training does not work. There is type 3 evidence to support the use of psychological interventions in dementia. There is type 2 evidence that a clinical diagnosis of dementia can be made accurately and that brain imaging increases that accuracy.Although the consensus statement dealt largely with medication, the role of dementia care in secondary services (geriatric medicine and old age psychiatry) and primary care, along with health economics, was discussed. There is ample evidence that there are effective treatments for people with dementia, and Alzheimer's disease in particular. Patients, their carers, and clinicians deserve to be optimistic in a field which often attracts therapeutic nihilism.

Abstract: Britain's National Institute for Health and Clinical Excellence (NICE) has recently issued guidance that restricts the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer's disease in the National Health Service. This stance contains lessons for designers of trials, drug regulators, health economists and those developing clinical guidelines for dementia care. The debates that took place around and within NICE were about identifying the benefits of these medicines and the beneficiaries, clarifying the costs of the medication and whom bears them, the methods of weighing benefit against cost, and the consequences of using different approaches to cost-benefit analysis. This article discusses each of these themes and outlines the changes in research and clinical practice and policy making that might flow from NICE's decisions on medication use. Outcome measures that capture changes in dementia syndromes need further development. Cost-benefit analysis needs refinement with better tools than quality-adjusted life-years, and the policy implications of restricting treatments in a progressive neurodegenerative disorder need more careful consideration.

Abstract: BACKGROUND: Timely recognition and diagnosis of dementia is the pre-condition for improving dementia care, but diagnosis often occurs late in the disease process. OBJECTIVE: To compare facilitators and obstacles to the timely recognition of dementia across eight European Union states, in order to implement established policies for earlier diagnosis. METHODS: A modified focus group technique, including a pre and posterior procedure. RESULTS: Twenty-three participants from different disciplines, purposively sampled for professional expertise in dementia research and innovative practice, attended two focus groups. Stigma in ageing and dementia, accompanied by a sense that there is little to offer until later on in the disease, underpinned the widespread reluctance of GPs to recognise dementia at an early stage and were major obstacles to the timely diagnosis of dementia across all eight countries. Dementia care services varied widely across Europe. Countries with the greatest development of dementia health care services were characterised by national guidelines, GPs fulfilling a gatekeeper function, multi-disciplinary memory clinics and innovative programmes that stimulated practice and new services. Dementia-related stigma was perceived as being less prominent in these countries. CONCLUSIONS: Overcome of delays in the timely diagnosis of dementia needs more than specialist services. They should address the processes associated with stigma, age and dementia, especially where these relate to physician practice and diagnostic disclosure. Stigma is perceived as variable across European States, with a promising finding that its impact is relatively small in countries with the widest range of dementia care services.
