Background: There is currently no disease-modifying treatment available to halt or delay the progression of the disease pathology in dementia. An agreed core set of the best-available and most appropriate outcomes for disease modification would facilitate the design of trials and ensure consistency across disease modification trials, as well as making results comparable and meta-analysable in future trials. Objectives: To agree a set of core outcomes for disease modification trials for mild to moderate dementia with the UK dementia research community and patient and public involvement (PPI). Data sources: We included disease modification trials with quantitative outcomes of efficacy from (1) references from related systematic reviews in workstream 1; (2) searches of the Cochrane Dementia and Cognitive Improvement Group study register, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Latin American and Caribbean Health Sciences Literature and PsycINFO on 11 December 2015, and clinical trial registries [International Standard Randomised Controlled Trial Number (ISRCTN) and clinicaltrials.gov] on 22 and 29 January 2016; and (3) hand-searches of reference lists of relevant systematic reviews from database searches. Review methods: The project consisted of four workstreams. (1) We obtained related core outcome sets and work from co-applicants. (2) We systematically reviewed published and ongoing disease modification trials to identify the outcomes used in different domains. We extracted outcomes used in each trial, recording how many used each outcome and with how many participants. We divided outcomes into the domains measured and searched for validation data. (3) We consulted with PPI participants about recommended outcomes. (4) We presented all the synthesised information at a conference attended by the wider body of National Institute for Health Research (NIHR) dementia researchers to reach consensus on a core set of outcomes. Results: We included 149 papers from the 22,918 papers screened, referring to 125 individual trials. Eighty-one outcomes were used across trials, including 72 scales [31 cognitive, 12 activities of daily living (ADLs), 10 global, 16 neuropsychiatric and three quality of life] and nine biological techniques. We consulted with 18 people for PPI. The conference decided that only cognition and biological markers are core measures of disease modification. Cognition should be measured by the Mini Mental State Examination (MMSE) or the Alzheimer’s Disease Assessment Scale – Cognitive subscale (ADAS-Cog), and brain changes through structural magnetic resonance imaging (MRI) in a subset of participants. All other domains are important but not core. We recommend using the Neuropsychiatric Inventory for neuropsychiatric symptoms: the Disability Assessment for Dementia for ADLs, the Dementia Quality of Life Measure for quality of life and the Clinical Dementia Rating scale to measure dementia globally. Limitations: Most of the trials inclu...

“…These studies suggested that the treatment may be beneficial but the differences between patients receiving treatment and those given the placebo were small and often not statistically significant. Another drug which may be effective is propentofylline [24][25][26], which strongly inhibits the potentially neurotoxic actions of activated microglia (free radical formation and transformation into brain macrophages). This drug may inhibit the progressive neurodegenerative process in dementia; however, randomized, double-blind placebocontrolled trials are required to establish whether this drug is effective.…”

Randomized controlled trials of primary and secondary prevention of vascular dementia demonstrate real effects on the cause or progression of disease (disease-modifying treatment). These strategies lead to a reduction in all cerebrovascular risk factors, in particular hypertension. Such treatment may prevent dementia by reducing stroke and possibly by other mechanisms that remain undetermined, such as those involved in neurodegeneration and cell death. Curative treatment of vascular dementia, particularly given recent studies on cholinesterase inhibitors (rivastigmine, donepezil and galantamine) and memantine, is still ineffective. There is insufficient evidence to support widespread use of these drugs in vascular dementia. Particular considerations should be taken into account in clinical trials. Vascular dementia is a heterogeneous disease with different subtypes and mechanisms. Therefore, well-designed, adequately powered trials accounting for this heterogeneity, with better clinical definitions and an assessment and detection of cognitive and global changes specific to vascular dementia, are needed.

Objective:To provide Canadian physicians and allied health care professionals with the evidence they need to help them make treatment decisions in the management of patients with Alzheimer’s disease or other dementias.Options:The full range and quality of diagnostic and therapeutic modalities available to Canadian physicians for the management of dementia.Outcomes:Improvement in the treatment of dementias, leading to reduced suffering, increased functional capacity and decreased economic burden.Evidence and values:The creation of these evidence-based consensus statements involved literature reviews of the subject by the authors; comparison of alternative clinical pathways and description of the methods whereby published data were analyzed; definition of the level of evidence for data in each case; evaluation and revision in a conference setting (involving primary care physicians, neurologists, psychiatrists, geriatricians, psychologists, consumers and other interested parties); insertion of tables showing key variables and data from various studies and tables of data with recommendations; and reassessment by all authors.Benefits, harms, and costs:A rational plan for the therapy of dementias is likely to lead to substantial benefits in both human and economic terms.Recommendations:Treatment decisions should be made taking into account the severity or stage of the disease, the availability of caregivers, the presence of disease affecting other bodily systems and the ability of the subject to pay the cost of the medications. Donepezil is considered to have positive effects upon certain tests of neuropsychological function and may produce some improvement in Alzheimer’s disease of mild to moderate severity as measured by rating scales. Its ability to improve quality of life remains uncertain. No other drug treatments* (apart from symptomatic therapies) are at present approved for the treatment of Alzheimer’s disease.Validation:These recommendations were created by a writing committee, evaluated and revised at a consensus conference and further reviewed and revised by the writing committee prior to publication.
