Randomized, placebo-controlled, clinical trial of donepezil in vascular dementia: differential effects by hippocampal size
Background and Purpose: We sought to assess the efficacy and safety of donepezil in patients with vascular dementia (VaD) fulfilling National Institute of Neurological Disorders and Stroke-Association Internationale pour la Recherche et l’Enseignement en Neurosciences criteria.; Methods: This international, multicenter, 24-week trial was conducted from March 2003 to August 2005. Patients (N=974; mean age, 73.0 […]

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 […]

Effect of modified huanglian wendan decoction in treating senile patients with mild cognitive impairment of turbid-phlegm blocking orifice syndrome
Objective: To observe the clinical efficacy of modified Huanglian Wendan Decoction (HWD) in treating senile mild cognitive impairment (MCI) of turbid-phlegm blocking orifice syndrome.; Methods: With a block randomized, double-blinded and controlled design adopted, the 64 patients of MCI selected from December 2007 to February 2009 were randomly and equally assigned to two groups. The […]

Clinical curative effect of Shenxiong Bushen Capsule and its effect on the quality of life of patients with Vascular dementia
Objective:; To observe clinical curative effect of Shenxiong Bushen Capsule for the treatment of mild vascular dementia (VaD), and probe the partial mechanism.; Methods: With a block random, double-blinded and controled clinical research method adopted, seventy patients with VaD were randomly assigned to two groups in a ratio of 5:2, including 50 cases in the […]

A 22-week, multicenter, randomized, double-blind controlled trial of Crocus sativus in the treatment of mild-to-moderate Alzheimer’s disease
Rationale: There is increasing evidence to suggest the possible efficacy of Crocus sativus (saffron) in the management of Alzheimer’s disease (AD).; Objective: The purpose of the present investigation was to assess the efficacy of C. sativus in the treatment of patients with mild-to-moderate AD.; Methods: Fifty-four Persian-speaking adults 55 years of age or older who […]

The ACTION study: methodology of a trial to evaluate safety and efficacy of a higher dose rivastigmine transdermal patch in severe Alzheimer’s disease
Background: Two sizes of rivastigmine patch (5 cm(2) and 10 cm(2)) are currently approved in the US and Europe, while a 20 cm(2) rivastigmine patch has also been tested. A 15 cm(2) rivastigmine patch may provide an optimal balance between efficacy and safety. Earlier studies have demonstrated the efficacy of rivastigmine in severe Alzheimer’s disease […]

A randomised clinical trial on a comprehensive geriatric assessment and intensive home follow-up after hospital discharge: the Transitional Care Bridge
Background: Older patients are at high risk for poor outcomes after acute hospital admission. The mortality rate in these patients is approximately 20%, whereas 30% of the survivors decline in their level of activities of daily living (ADL) functioning three months after hospital discharge. Most diseases and geriatric conditions that contribute to poor outcomes could […]

Human Albumin Grifols 5% in plasmapheresis: a new therapy involving beta-amyloid mobilisation in Alzheimer’s disease
Introduction and Aims: Results from a pilot study and its 2-year extension (IG0502) performed on patients with mild or moderate Alzheimer’s disease revealed a tendency towards clinical stabilization after a plasmapheresis program with plasma exchange with therapeutic albumin Human Albumin Grifols 5%. Plasma levels of Alphabeta(40) and Alphabeta(42) presented a saw-tooth pattern associated to plasma […]
