AIMS It is unclear whether the cognitive dysfunction associated with heart failure (HF) is due to HF or comorbid conditions such as ischaemic heart disease (IHD). This study aimed to determine whether, compared with controls with and without IHD, adults with systolic HF show evidence of cognitive impairment and cerebral grey matter (GM) loss. METHODS AND(More)
BACKGROUND Elevated total plasma homocysteine (tHcy) has been associated with cognitive impairment, vascular disease and brain atrophy. METHODS We investigated 150 volunteers to determine if the association between high tHcy and cerebral grey matter volume and cognitive function is independent of cardiovascular disease. RESULTS Participants with high(More)
There has been increasing interest in the influence of diet on cognition in the elderly. This study examined the cross-sectional association between dietary patterns and cognition in a sample of 249 people aged 65-90 years with mild cognitive impairment (MCI). Two dietary patterns; whole and processed food; were identified using factor analysis from a(More)
BACKGROUND Use of potentially harmful medications (PHMs) is common in people with dementia living in Residential Aged Care Facilities (RACFs) and increases the risk of adverse health outcomes. Debate persists as to how PHM use and its association with quality of life should be measured. We designed this study to determine the association of exposure to PHM,(More)
Impaired awareness of cognitive deficits is a common symptom of dementia, but its prognostic importance in people with cognitive impairment-no dementia (CIND) is uncertain. In this study, we examined whether community volunteers with CIND and reduced awareness had worse cognitive performance and cognitive decline over 18 months than CIND participants with(More)
BACKGROUND Residential care is important for older adults, particularly for those with advanced dementia and their families. Education interventions that achieve sustainable improvement in the care of older adults are critical to quality care. There are few systematic data available regarding the educational needs of Residential Care Facility (RCF) staff(More)
—Ant Colony Optimisation (ACO) algorithms use two heuristics to solve computational problems: one long-term (pheromone) and the other short-term (local heuristic). This paper details the development of antennation, a mid-term heuristic based on an analogous process in real ants. This is incorporated into ACO for the Travelling Salesman Problem (TSP).(More)
Transparency and open communication are key to a healthy relationship edical practice these days is influenced to a large extent by clinical practice guidelines. Usually sponsored by professional bodies, these compendia of advice should be produced by groups of experts with broad representation and credibility. These experts are expected to follow clearly(More)
