Aerobic exercise increases hippocampal volume in older women with probable mild cognitive impairment: a 6-month randomised controlled trial
Background: Mild cognitive impairment (MCI) is a well-recognised risk factor for dementia and represents a vital opportunity for intervening. Exercise is a promising strategy for combating cognitive decline by improving brain structure and function. Specifically, aerobic training (AT) improved spatial memory and hippocampal volume in healthy community-dwelling older adults. In older women with probable MCI, […]

FMRI connectivity analysis of acupuncture effects on the whole brain network in mild cognitive impairment patients
The increased risk for the elderly with mild cognitive impairment (MCI) to progress to Alzheimer’s disease makes it an appropriate condition for investigation. While the use of acupuncture as a complementary therapeutic method for treating MCI is popular in certain parts of the world, the underlying mechanism is still elusive. We sought to investigate the […]

Mnemonic strategy training improves memory for object location associations in both healthy elderly and patients with amnestic mild cognitive impairment: a randomized, single-blind study
Objective: To evaluate the efficacy of mnemonic strategy training versus a matched-exposure control condition and to examine the relationship between training-related gains, neuropsychological abilities, and medial temporal lobe volumetrics in patients with amnestic mild cognitive impairment (aMCI) and age-matched healthy controls.; Method: Twenty-three of 45 screened healthy controls and 29 of 42 screened patients with […]

Effects of liraglutide on neurodegeneration, blood flow and cognition in Alzheimer´s disease – protocol for a controlled, randomized double-blinded trial
Introduction: Type 2 diabetes (DM-2) increases the risk of developing Alzheimer´s disease (AD), and patients with AD are more likely to develop DM-2. DM-2 and AD share some pathophysiological features. In AD, amyloid-β (Aβ) is accumulated as extracellular plaques in the gray matter of the brain, while in DM-2 islet amyloid polypeptide (IAPP) is accumulated […]

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 […]

Is high oral dose L-arginine intake effective in leukoaraiosis? Preliminary data, study protocol and expert’s opinion
Background: Leukoraraiosis is worldwide considered as a part of the normal aging process, although it is strongly associated with dementia and other disabilities. The pathogenesis of leukoaraiosis still has not been thoroughly acknowledged, even though chronic ischemia with consequent arteriolosclerosis probably due to endothelial dysfunction has been suggested. Treatment focuses on prevention of lesion formation […]

Mnemonic strategy training partially restores hippocampal activity in patients with mild cognitive impairment
Learning and memory deficits typify patients with mild cognitive impairment (MCI) and are generally attributed to medial temporal lobe dysfunction. Although the hippocampus is perhaps the most commonly studied neuroanatomical structure in these patients, there have been few attempts to identify rehabilitative interventions that facilitate its functioning. Here, we present results from a randomized, controlled, […]

Concord grape juice supplementation and neurocognitive function in human aging
Polyphenol compounds found in berry fruits, in particular flavonoids, have been associated with health benefits including improvement in cognition and neuronal function with aging. Concord grape juice contains polyphenols, including anthocyanins and flavanols, and previous research has shown improvement in a number of human health conditions with grape juice supplementation. In the current study, older […]

Memantine prevents hypoglycemia-induced decrements of the cerebral energy status in healthy subjects
Context: The risk to develop dementia is significantly increased in diabetes mellitus. Memantine, an N-methyl-D-aspartate receptor antagonist, which is clinically applied in dementia, has been shown to exert neuroprotective effects under hypoglycemic conditions in rats.; Objective: We hypothesized that memantine may prevent hypoglycemia-induced decrements in the cerebral high-energy phosphate, i.e. ATP, metabolism to exert its […]

Magnetic resonance imaging and neuropsychological results from a trial of memantine in Alzheimer’s disease
Background: This study was designed to assess changes in brain volume and cognitive abilities in memantine-treated patients with Alzheimer’s disease (AD) by using an exploratory, single-arm, delayed-start design.; Methods: Cholinesterase inhibitor-treated patients with AD (N = 47; Mini-Mental State Examination score range: 15-23) were enrolled in an observational lead-in period (weeks: 1-24), followed by an […]
