BACKGROUND Cholinesterase inhibitors produce small improvements in cognitive and global assessments in Alzheimer's disease. We aimed to determine whether donepezil produces worthwhile improvements in disability, dependency, behavioural and psychological symptoms, carers' psychological wellbeing, or delay in institutionalisation. If so, which patients(More)
BACKGROUND Clinical trials have shown the benefits of cholinesterase inhibitors for the treatment of mild-to-moderate Alzheimer's disease. It is not known whether treatment benefits continue after the progression to moderate-to-severe disease. METHODS We assigned 295 community-dwelling patients who had been treated with donepezil for at least 3 months and(More)
BACKGROUND There are difficulties in obtaining health-related quality of life (HRQL) data from patients with dementia due to variation in their cognitive ability, degree of insight and capacity to make judgments. The use of proxies is one solution. OBJECTIVES To examine the inter-rater agreement of patient and proxy completion of the EuroQol EQ-5D(More)
OBJECTIVES Caregiver burden is a key measure in caregiver research and is frequently used as a baseline measure in intervention studies. Previous research has found numerous factors associated with caregiver burden such as the relationship quality between carer and patient, the patient's cognitive ability, behavioural and psychological symptoms displayed by(More)
BACKGROUND As tau aggregation pathology correlates with clinical dementia in Alzheimer's disease (AD), a tau aggregation inhibitor (TAI) could have therapeutic utility. Methylthioninium (MT) acts as a selective TAI in vitro and reduces tau pathology in transgenic mouse models. OBJECTIVE To determine the minimum safe and effective dose of MT required to(More)
BACKGROUND/AIMS Alzheimer disease (AD) patients commonly suffer from behavioural and psychological symptoms of dementia (BPSD). A genetic component to BPSD development in AD has been demonstrated. This is an investigation of whether the linked polymorphic region and variable number tandem repeat variants of the serotonin transporter (SERT) are associated(More)
BACKGROUND Depression is common in dementia but the evidence base for appropriate drug treatment is sparse and equivocal. We aimed to assess efficacy and safety of two of the most commonly prescribed drugs, sertraline and mirtazapine, compared with placebo. METHODS We undertook the parallel-group, double-blind, placebo-controlled, Health Technology(More)
BACKGROUND Autopsy studies suggest that Wernicke-Korsakoff Syndrome (WKS) is not a rare disorder, particularly in individuals who abuse alcohol. Thiamine has been established as the treatment of choice for over 50 years, but there is uncertainty about appropriate dosage and duration. Current practice guidelines are based on case reports and clinical(More)
The first genome-wide association in Alzheimer's disease (AD) suggested that the GAB2 gene rs2373115 polymorphism may be a strong risk factor in APOE varepsilon4-carriers. We failed to detect an association of rs2373115 with the risk of developing AD in three populations (totalling 1406 controls and 1749 AD cases) whatever the APOE status, even if we(More)
There are measurement difficulties associated with the assessment of health-related quality of life (HRQL) in older people with dementia. The use of proxies is a commonly employed approach to overcome such problems. The research reported in this paper sought to identify, specifically for the EuroQol EQ-5D HRQL instrument, whether construct validity is(More)
