A phase 2 randomized trial of ELND005, scyllo-inositol, in mild to moderate Alzheimer disease
Objective: This randomized, double-blind, placebo-controlled, dose-ranging phase 2 study explored safety, efficacy, and biomarker effects of ELND005 (an oral amyloid anti-aggregation agent) in mild to moderate Alzheimer disease (AD).; Methods: A total of 353 patients were randomized to ELND005 (250, 1,000, or 2,000 mg) or placebo twice daily for 78 weeks. Coprimary endpoints were the […]

A phase II trial of huperzine A in mild to moderate Alzheimer disease
Objective: Huperzine A is a natural cholinesterase inhibitor derived from the Chinese herb Huperzia serrata that may compare favorably in symptomatic efficacy to cholinesterase inhibitors currently in use for Alzheimer disease (AD).; Methods: We assessed the safety, tolerability, and efficacy of huperzine A in mild to moderate AD in a multicenter trial in which 210 […]

Effects of hormone therapy on depressive symptoms and cognitive functions in women with Alzheimer disease: a 12 month randomized, double-blind, placebo-controlled study of low-dose estradiol and norethisterone
Objective: To elucidate the effects of low-dose 17beta-estradiol and norethisterone (hormone therapy [HT]) versus placebo in women with Alzheimer Disease (AD) on cognition, depressive symptoms, and activities of daily living.; Design: A 12-month randomized, double-blind, placebo-controlled study, stratified by apolipoprotein E (ApoE) genotype (with versus without the epsilon4 allele), duration of education (< or =9 […]

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 […]

Effect of CYP2D6*10 and APOE polymorphisms on the efficacy of donepezil in patients with Alzheimer’s disease
Background: The aim of this study was to evaluate the effect of CYP2D6*10 and APOE polymorphisms on both steady-state plasma concentrations (Cp) and clinical response of donepezil in patients with mild-to-moderate Alzheimer’s disease (AD).; Methods: A total of 110 Chinese AD patients participated in this study. Patients were treated with 5 to 10 mg of […]

Effects of atorfastatin on the cognitive function of patients with vascular cognitive impairment and different apolipoprotein E genotypes
Objective: To study the effect of atorfastatin on the cognitive function of patients with vascular cognitive impairment (VCI) and different apolipoprotein E genotypes.; Methods: The ApoE polymorphism was genotyped by PCR sequencing and the patients were divided into Eepsilon4 carrier (epsilon4+) group (n=24) and epsilon4- group (n=51). All the patients were given 20 mg oral […]

Serotonin transporter triallelic genotype and response to citalopram and risperidone in dementia with behavioral symptoms
The risk/benefit ratio of pharmacotherapy for behavioral symptoms of dementia is questionable: second-generation antipsychotics are poorly tolerated, and the efficacy of alternative treatments, for example, selective serotonin-reuptake inhibitors (SSRIs), is uncertain. Biomarkers of treatment response may improve this risk/benefit ratio. The length polymorphism of the serotonin transporter promoter gene (5-HTTLPR/SLC6A4) may moderate tolerability of SSRIs […]

Cognitive effects of memantine in postmenopausal women at risk of dementia: a pilot study
Background: To determine the effects of memantine on cognition in a normal population of postmenopausal women with putative risk factors for Alzheimer’s disease (AD) using a built-in control for the genetic risk factor for AD (apoE-epsilon4 status).; Methods: A prospective, open-label, 6-month pilot medication trial with memantine and follow-up after discontinuance conducted at the Center […]

Effects of insulin and octreotide on memory and growth hormone in Alzheimer’s disease
Both insulin alone and the somatostatin analogue octreotide alone facilitate memory in patients with Alzheimer’s disease (AD). Since octreotide inhibits endogenous insulin secretion, the cognitive effects of insulin and octreotide may not be independent. This study tested the individual and interactive effects of insulin and octreotide on memory and plasma growth hormone (GH) levels in […]

New insights into clinical trial for Colostrinin in Alzheimer’s disease
Background: The pathomechanism of Alzheimer’s disease (AD) is multifactorial although the most popular hypotheses are centered on the effects of the misfolded, aggregated protein, amyloid beta (Abeta) and on Tau hyperphosphorylation.; Objectives: Double blinded clinical trials were planned to demonstrate the effect of Colostrinin (CLN) on instrumental daily activities of AD patients. The potential molecular […]
