A randomized pilot clinical trial of the safety of pioglitazone in treatment of patients with Alzheimer disease
Objectives: To evaluate the safety of the peroxisome proliferator-activated receptor gamma agonist pioglitazone in nondiabetic patients with Alzheimer disease (AD) and to explore treatment effect sizes on clinical outcomes.; Design: Double-blind, placebo-controlled randomized controlled trial of 18-month duration.; Setting: Two academic medical center outpatient clinics.; Patients: Nondiabetic patients meeting research criteria for probable AD were […]
Effect of an antioxidant drink on homocysteine levels in Alzheimer’s patients

Parra, S.,
Vidal-Guevara, M. L.
Background: A large body of evidence supports a role of oxidative stress in Alzheimer disease (AD) and in cerebrovascular disease. Blood levels of homocysteine may be increased in AD and hyperhomocysteinemia may contribute to disease pathophysiology by vascular and direct neurotoxic mechanisms. Even in the absence of vitamin deficiency, plasma total homocysteine (tHcy) concentration may […]

Omega-3 fatty acids, e.g., dokosahexaenoic acid (DHA) and eikosapentaenoic acid (EPA), ameliorate inflammatory reactions by various mechanisms, but the role of prostaglandins remains unclear. Our aim was to determine if dietary supplementation with a DHA-rich fish oil influenced the release of PGF(2alpha) from peripheral blood mononuclear cells (PBMC). In the OmegAD study, 174 Alzheimer disease […]

Preclinical and clinical studies gave evidence that lithium could be useful in the treatment of Alzheimer’s disease (AD). One possible mechanism of action might be the induction of neurotrophins. Recently, we found a significant increase of brain-derived neurotrophic factor (BDNF) serum levels in AD patients treated with lithium and a significant decrease of ADAS Cog […]
The prevention of hip fracture with menatetrenone and risedronate plus calcium supplementation in elderly patients with Alzheimer disease: a randomized controlled trial

A high incidence of fractures, particularly of the hip, represents an important problem in patients with Alzheimer disease (AD), who are prone to falls and have osteoporosis. We previously found that vitamin K deficiency and low 25-hydroxyvitamin D (25-OHD) with compensatory hyperparathyroidism cause reduced bone mineral density (BMD) in female patients with AD. This may […]
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 […]

A combination of green tea extract and l-theanine (LGNC-07) has been reported to have beneficial effects on cognition in animal studies. In this randomized, double-blind, placebo-controlled study, the effect of LGNC-07 on memory and attention in subjects with mild cognitive impairment (MCI) was investigated. Ninety-one MCI subjects whose Mini Mental State Examination-K (MMSE-K) scores were […]
Down syndrome and dementia: a randomized, controlled trial of antioxidant supplementation

Head, Elizabeth,
Gillen, Daniel L.
Individuals with Down syndrome over age 40 years are at risk for developing dementia of the Alzheimer type and have evidence for chronic oxidative stress. There is a paucity of treatment trials for dementia in Down syndrome in comparison to Alzheimer disease in the general (non-Down syndrome) population. This 2-year randomized, double-blind, placebo-controlled trial assessed […]
A randomized placebo controlled trial of homocysteine lowering to reduce cognitive decline in older demented people

Choi, K. C.,
Lam, L. C.
Introduction: Whether homocysteine lowering by B vitamins can reduce cognitive decline in Alzheimer disease and vascular dementia patients is unclear.; Methods and Materials: 140 subjects with mild to moderate Alzheimer disease or vascular dementia were randomly assigned to take 1 mg of methylcobalamin and 5 mg of folic acid, or placebo once daily for 24 […]
