Background: Memantine is an approved symptomatic treatment for moderate to severe Alzheimer’s disease that reduces the excitotoxic effects of hyperactive glutamatergic transmission. However, the exact mechanism of the effect of memantine in Alzheimer’s disease patients is poorly understood. Importantly, the default mode network (DMN), which plays a key role in attention, is hypoactive in Alzheimer’s […]
Persons with mild or moderate Alzheimer’s disease use a basic orientation technology to travel to different rooms within a day center

This study assessed whether three patients with Alzheimer’s disease could learn to use a basic orientation technology to reach different rooms within a day center. At each travel instance, the technology provided verbal messages (cues) from the room to reach. For the first two patients, the messages were presented at intervals of about 15s. For […]
Effect of an antioxidant drink on homocysteine levels in Alzheimer’s patients
Morillas-Ruiz, J. M.,
Rubio-Perez, J. M.,
Albaladejo, M. D.,
Zafrilla, P.,
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 […]
Reduced prostaglandin F2 alpha release from blood mononuclear leukocytes after oral supplementation of omega3 fatty acids: the OmegAD study

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 […]
Influence of lithium treatment on GDNF serum and CSF concentrations in patients with early Alzheimer’s disease
Straten, Guido,
Saur, Ralf,
Laske, Christoph,
Gasser, Thomas,
Annas, Peter,
Basun, Hans,
Leyhe, Thomas
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 […]
Improved language performance in Alzheimer disease following brain stimulation
Cotelli, Maria,
Calabria, Marco,
Manenti, Rosa,
Rosini, Sandra,
Zanetti, Orazio,
Cappa, Stefano F.,
Miniussi, Carlo
Objectives: Repetitive transcranial magnetic stimulation (rTMS) has been proposed as a possible treatment for the cognitive deficits associated with Alzheimer disease (AD). The aim of this study was to assess the long-term effects, on cognitive performance, of rTMS applied to the left dorsolateral prefrontal cortex (DLPFC) in AD patients.; Methods: Ten AD patients were randomly […]
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 […]
