Study of the effects of vinpocetin on cognitive functions
Introduction: Chronic cerebral hypoperfusion is a risk factor for the development of certain types of dementia. Mild cognitive impairment is a stage of predementia condition, because the symptoms are similar but not as severe as the symptoms in patients with dementia. Vinpocetine, due to its complex mechanism of action, has an important role in the […]
Reduction of hippocampal hyperactivity improves cognition in amnestic mild cognitive impairment
Elevated hippocampal activation is observed in conditions that confer risk for Alzheimer’s disease, including amnestic mild cognitive impairment (aMCI). Studies in relevant animal models have indicated that overactivity in selective hippocampal circuits contributes to cognitive impairment. Here, we tested the effect of reducing hippocampal activation in aMCI. Under placebo treatment, hippocampal activation in the dentate […]
Donepezil for dementia with Lewy bodies: a randomized, placebo-controlled trial
Objective: Because cholinergic deficits are prominent in dementia with Lewy bodies (DLB), we investigated the effects of a cholinesterase inhibitor, donepezil, in such patients in a randomized, double-blind, placebo-controlled exploratory phase 2 trial.; Methods: One-hundred forty patients with DLB, recruited from 48 specialty centers in Japan, were randomly assigned to receive placebo or 3, 5, […]
