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 […]

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 […]

Here we report the first multi-center clinical trial in Alzheimer’s disease (AD) using fluorodeoxyglucose positron emission tomography ([18F]FDG-PET) measures of brain glucose metabolism as the primary outcome. We contrasted effects of 12 months treatment with the PPARγ agonist Rosiglitazone XR versus placebo in 80 mild to moderate AD patients. Secondary objectives included testing for reduction […]
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 […]
Improved visual hallucination by donepezil and occipital glucose metabolism in dementia with Lewy bodies: the Osaki-Tajiri project

Kasuya, Masashi,
Ishii, Hiroshi,
Yamaguchi, Satoshi
Deficits in the cholinergic system are pronounced in dementia with Lewy bodies (DLB) and are more severe in patients with visual hallucinations (VHs). The aim is to identify the occipital glucose metabolism patterns by positron emission tomography (PET) and the changes following donepezil treatment. 13 DLB patients with VHs were enrolled in the study. After […]

To test the effects of the PPAR-γ agonist pioglitazone on cognition, regional cerebral blood flow (rCBF), and plasma levels of Aβ40 and Aβ42, we conducted a 6-month, randomized, open-controlled trial in patients with mild Alzheimer disease (AD) accompanied with type II diabetes mellitus. We randomly assigned 42 patients to either the group treated with 15-30 […]
The prevention of hip fracture with menatetrenone and risedronate plus calcium supplementation in elderly patients with Alzheimer disease: a randomized controlled trial

Matsumoto, Hideo
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 […]
Effects of a 6-month cognitive intervention on brain metabolism in patients with amnestic MCI and mild Alzheimer’s disease

The effect of cognitive intervention on brain metabolism in AD is largely unexplored. Therefore, we aimed to investigate cognitive parameters and 18FDG PET to test for effects of a cognitive intervention in patients with aMCI or mild AD. Patients with aMCI (N = 24) or mild AD (N = 15) were randomly assigned either to […]

Objectives: Magnetic Resonance Spectroscopy (MRS) may provide a precise and reliable assessment of the extent and severity of neural tissue loss caused by various diseases. In particular, the N-Acetyl Aspartate (NAA) and Creatine (Cr) ratio has been found to be an indicator of the degree of neuronal loss in Alzheimer’s disease (AD). Memantine is thought […]
Improved social interaction and increased anterior cingulate metabolism after group reminiscence with reality orientation approach for vascular dementia

Tanaka, Naofumi
A group reminiscence approach (GRA) with reality orientation (RO) is widely used as a psychosocial intervention for dementia. Since clinical effectiveness was reported for the intervention, interest has been directed toward areas of the neuronal network that might be being stimulated. We hypothesized that the frontal lobe associated with social interaction was being stimulated. To […]
