Serotonergic function and treatment of behavioral and psychological symptoms of frontotemporal dementia
Herrmann, Nathan,
Black, Sandra E.,
Chow, Tiffany,
Cappell, Jaclyn,
Tang-Wai, David F.,
Lanctôt, Krista L.
Objectives: The purposes of this study were first, to evaluate the effectiveness of citalopram in treating behavioral disturbances in frontotemporal dementia (FTD) subjects and second, to determine whether an association exists between serotonergic function, as determined by a neuroendocrine challenge, and treatment response.; Design: Single-dose citalopram (30 mg per os) challenge followed by a 6-week […]
Diagnostic and economic evaluation of new biomarkers for Alzheimer’s disease: the research protocol of a prospective cohort study

Background: New research criteria for the diagnosis of Alzheimer’s disease (AD) have recently been developed to enable an early diagnosis of AD pathophysiology by relying on emerging biomarkers. To enable efficient allocation of health care resources, evidence is needed to support decision makers on the adoption of emerging biomarkers in clinical practice. The research goals […]
High-intensity physical activity modulates diet effects on cerebrospinal amyloid-β levels in normal aging and mild cognitive impairment

We previously showed that amyloid-β 1-42 (Aβ(42)) levels in cerebrospinal fluid (CSF) were markedly altered in response to a 4-week dietary intervention in normal aging and mild cognitive impairment (MCI). Here, we re-examined the data to assess whether diet-induced effects on CSF Aβ(42) were modulated by high intensity physical activity (hi-PA). Normal older adults (n […]
Effect of immunotherapy with bapineuzumab on cerebrospinal fluid biomarker levels in patients with mild to moderate Alzheimer disease
Blennow, Kaj,
Zetterberg, Henrik,
Rinne, Juha O.,
Salloway, Stephen,
Wei, Jenny,
Black, Ronald,
Grundman, Michael,
Liu, Enchi
Background: Given the slow and variable clinical course of Alzheimer disease, very large and extended clinical trials are needed to identify a beneficial clinical effect of disease-modifying treatments. Therefore, biomarkers are essential to prove that an anti-β-amyloid (Aβ) drug candidate affects both Aβ metabolism and plaque load as well as downstream pathogenic mechanisms.; Objective: To […]
Safety, tolerability, and antibody response of active Aβ immunotherapy with CAD106 in patients with Alzheimer’s disease: randomised, double-blind, placebo-controlled, first-in-human study

Lundmark, Joens,
Staufenbiel, Matthias,
Orgogozo, Jean-Marc,
Graf, Ana
Background: Immunotherapy targeting the amyloid β (Aβ) peptide is a potential strategy to slow the progression of Alzheimer’s disease. We aimed to assess the safety and tolerability of CAD106, a novel active Aβ immunotherapy for patients with Alzheimer’s disease, designed to induce N-terminal Aβ-specific antibodies without an Aβ-specific T-cell response.; Methods: We did a phase […]
Antioxidants for Alzheimer disease: a randomized clinical trial with cerebrospinal fluid biomarker measures

Quinn, Joseph F.,
Ringman, John M.,
Jicha, Gregory A.,
Cotman, Carl,
Cottrell, Barbara,
Montine, Thomas J.,
Thomas, Ronald G.,
Aisen, Paul
Objective: To evaluate whether antioxidant supplements presumed to target specific cellular compartments affected cerebrospinal fluid (CSF) biomarkers.; Design: Double-blind, placebo-controlled clinical trial.; Setting: Academic medical centers.; Participants: Subjects with mild to moderate Alzheimer disease.; Intervention: Random assignment to treatment for 16 weeks with 800 IU/d of vitamin E (α-tocopherol) plus 500 mg/d of vitamin C […]
Validation of AclarusDx™, a blood-based transcriptomic signature for the diagnosis of Alzheimer’s disease

Einstein, Richard,
Vellas, Bruno
Biomarkers have gained an increased importance in the past years in helping physicians to diagnose Alzheimer’s disease (AD). This study was designed to identify a blood-based, transcriptomic signature that can differentiate AD patients from control subjects. The performance of the signature was then evaluated for robustness in an independent blinded sample population. RNA was extracted […]
Increased CSF APPs-α levels in patients with Alzheimer disease treated with acitretin
Endres, Kristina,

Objective: We investigated induction of α-secretase A disintegrin and metalloprotease 10 (ADAM10) by the synthetic retinoid acitretin (Neotigason; Actavis, München-Riem, Germany) in patients with mild to moderate Alzheimer disease (AD) via measurement of CSF content of α-secretase-derived amyloid precursor protein (APPs-α).; Methods: Twenty-one patients clinically diagnosed with mild to moderate AD received acitretin (30 mg […]
