BACKGROUND Dementia with Lewy bodies is a common form of dementia in the elderly, characterised clinically by fluctuating cognitive impairment, attention deficits, visual hallucinations, parkinsonism, and other neuropsychiatric features. Neuroleptic medication can provoke severe sensitivity reactions in patients with dementia of this type. Many deficits in(More)
OBJECTIVES To assess the effects of rivastigmine on the core domains of Alzheimer's disease. DESIGN Prospective, randomised, multicentre, double blind, placebo controlled, parallel group trial. Patients received either placebo, 1-4 mg/day (lower dose) rivastigmine, or 6-12 mg/day (higher dose) rivastigmine. Doses were increased in one of two fixed dose(More)
Alzheimer's disease (AD) is the most common cause of dementia worldwide. The etiology is multifactorial, and pathophysiology of the disease is complex. Data indicate an exponential rise in the number of cases of AD, emphasizing the need for developing an effective treatment. AD also imposes tremendous emotional and financial burden to the patient's family(More)
The efficacy of a centrally active cholinesterase inhibitor, rivastigmine tartrate (ENA 713; Exelon, in patients with mild to moderately severe Alzheimer's disease was evaluated in a 26-week open-label extension of a 26-week, double-blind, placebo-controlled study. By 52 weeks, patients originally treated with 6-12 mg/day rivastigmine had significantly(More)
Rivastigmine is a carbamate acetylcholinesterase (AChE) inhibitor with central selectivity. Early studies showed that daily doses up to 6 mg/day have some efficacy in patients with dementia of the Alzheimer type (DAT). The present study was designed to assess the safety, tolerability and efficacy of rivastigmine at doses up to 12 mg/day. A total of 114(More)
A clinicopathological study of 206 Indian children with nephrotic syndrome showed a primary renal cause in 195 (96%), of which 77% were boys. In 126 children (96 boys, 30 girls) onset of the disorder occurred before the age of 5 years. Renal biopsy showed minimal lesions in 150 patients (77%); in 85 of these biopsy was done 3 months to 16 years after onset(More)
OBJECTIVE To investigate whether or not a coding polymorphism in the cystatin C gene (CST3) contributes risk for AD. DESIGN A case-control genetic association study of a Caucasian dataset of 309 clinic- and community-based cases and 134 community-based controls. RESULTS The authors find a signficant interaction between the GG genotype of CST3 and(More)
In this study 26 healthy volunteers received scopolamine 0.7 mg subcutaneously on seven occasions at least a week apart. Cognitive efficiency was measured with a test battery before and 60 min following scopolamine on each occasion. Following this, over the seven occasions, a range of oral and intravenous dose regimens were administered including aniracetam(More)
In-vivo metabolic measures with positron emission tomography using (18)F-fluorodeoxyglucose (FDG-PET) have demonstrated hypometabolism in temporal, frontal, and hippocampal areas during the early stages of Alzheimer's disease (AD). Progression of the dementia in AD involves compromised cholinergic functioning. Cholinesterase inhibitors have demonstrated(More)
This study was designed to assess the effects of rivastigmine (Exelon) on the cognitive functioning of patients suffering from dementia with Lewy bodies. This was a prospective, multi-centre, randomised, double-blind, placebo-controlled exploratory study conducted at sites in the UK, Spain and Italy. The treatment period was 20 weeks with a 3-week(More)
