Effects of simvastatin on cholesterol metabolism and Alzheimer disease biomarkers

Preclinical and epidemiologic studies suggest a protective effect of statins on Alzheimer disease (AD). Experimental evidence indicates that some statins can cross the blood-brain barrier, alter brain cholesterol metabolism, and may ultimately decrease the production of amyloid-beta (Abeta) peptide. Despite these promising leads, clinical trials have yielded inconsistent results regarding the benefits of statin treatment […]

An MRI substudy of a donepezil clinical trial in mild cognitive impairment

A magnetic resonance imaging (MRI) study was conducted as part of an intervention study in subjects with amnestic mild cognitive impairment (aMCI) to assess donepezil’s treatment effect on brain atrophy. Adults with aMCI were randomly assigned to double-blind treatment with 10 mg/day donepezil hydrochloride or placebo for 48 weeks. Brain MRI scans were acquired at […]

Donepezil treatment in Alzheimer’s disease patients with and without cerebrovascular lesions: a preliminary report

Aim: Donepezil has not been evaluated in Korean patients with Alzheimer’s disease (AD) for up to 1 year. The objectives of this study were to evaluate the differential efficacy of donepezil in Korean AD patients with and without concomitant cerebrovascular lesions (CVL).; Methods: This study was a 48-week open-label trial of donepezil in patients with […]

Long-term effects of galantamine treatment on brain functional activities as measured by PET in Alzheimer’s disease patients

The effects of galantamine (16 to 24 mg/day) treatment on brain functional activities (blood flow and glucose metabolism) were examined in 18 patients with mild Alzheimer’s disease (AD) in relation to brain acetylcholinesterase (AChE) activity and nicotinic receptors and cognitive function. The study consisted of an initial double-blind phase of three months (short-term) followed by […]

Docosahexaenoic acid supplementation and cognitive decline in Alzheimer disease: a randomized trial

Context: Docosahexaenoic acid (DHA) is the most abundant long-chain polyunsaturated fatty acid in the brain. Epidemiological studies suggest that consumption of DHA is associated with a reduced incidence of Alzheimer disease. Animal studies demonstrate that oral intake of DHA reduces Alzheimer-like brain pathology.; Objective: To determine if supplementation with DHA slows cognitive and functional decline […]

Persistence of the effects of Cerebrolysin on cognition and qEEG slowing in vascular dementia patients: results of a 3-month extension study

The maintenance of the effects of Cerebrolysin, a peptidergic compound with neurotrophic activity, on cognitive performance and qEEG activity was investigated through a 12-week, open-label extension of a 4-week, randomised, placebo-controlled pilot study. Thirty-three out of 41 patients with mild-to-moderate severe probable vascular dementia (VaD) according to NINDS-AIREN participating in the double-blind phase of the […]

Effects of memantine on clinical ratings, fluorodeoxyglucose positron emission tomography measurements, and cerebrospinal fluid assays in patients with moderate to severe Alzheimer dementia: a 24-week, randomized, clinical trial

Most experts consider that memantine has a symptomatic treatment, but clinical trials have not yet provided compelling evidence to support a disease-modifying effect. We investigate the effects of memantine on clinical ratings; fluorodeoxyglucose positron emission tomography (FDG-PET) measurements, which can monitor disease-modifying effect; and cerebrospinal fluid (CSF) assays in patients with moderate to severe probable […]

Postmenopausal hormone therapy and subclinical cerebrovascular disease: the WHIMS-MRI Study

Objective: The Women’s Health Initiative Memory Study (WHIMS) hormone therapy (HT) trials reported that conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA) increases risk for all-cause dementia and global cognitive decline. WHIMS MRI measured subclinical cerebrovascular disease as a possible mechanism to explain cognitive decline reported in WHIMS.; Methods: We contacted 2,345 women […]

Alzheimer’s Disease Anti-inflammatory Prevention Trial: design, methods, and baseline results

Background: The Alzheimer’s Disease Anti-inflammatory Prevention Trial (ADAPT) was designed to address whether non-steroidal anti-inflammatory drugs (NSAIDs) can prevent or delay the onset of Alzheimer’s disease (AD).; Methods: ADAPT was a randomized, double-placebo-controlled, multicenter chemoprevention trial conducted at six U.S. dementia research clinics. At entry, participants were required to test “normal” on a battery of […]

A phase I trial of deep brain stimulation of memory circuits in Alzheimer’s disease

Objective: Alzheimer disease (AD) is characterized by functional impairment in the neural elements and circuits underlying cognitive and memory functions. We hypothesized that fornix/hypothalamus deep brain stimulation (DBS) could modulate neurophysiological activity in these pathological circuits and possibly produce clinical benefits.; Methods: We conducted a phase I trial in 6 patients with mild AD receiving […]
