Efficacy of PPAR-γ agonist pioglitazone in mild Alzheimer disease

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 […]

Rosiglitazone monotherapy in mild-to-moderate Alzheimer’s disease: results from a randomized, double-blind, placebo-controlled phase III study

Background/aims: A phase II study of the peroxisome proliferator-activated receptor-γ agonist rosiglitazone extended release (RSG XR) in mild-to-moderate Alzheimer’s disease (AD) detected a treatment benefit to cognition in apolipoprotein E(APOE)-ε4-negative subjects. The current phase III study with prospective stratification by APOE genotype was conducted to confirm the efficacy and safety of RSG XR in mild-to-moderate […]

Dopamine D₂-agonist rotigotine effects on cortical excitability and central cholinergic transmission in Alzheimer’s disease patients

Dopamine is a neurotransmitter involved in several brain functions ranging from emotions control, movement organization to memory formation. It is also involved in the regulation of mechanisms of synaptic plasticity. However, its role in Alzheimer’s disease (AD) pathogenesis is still puzzling. Several recent line of research instead indicates a clear role for dopamine in both […]
