A multicenter, double-blind, placebo-controlled trial of the PDE9A inhibitor, PF-04447943, in Alzheimer’s disease

Background: PF-04447943 is a potent, selective phosphodiesterase 9A (PDE9A) inhibitor that elevates guanoscine 3′,5′ – cyclic monophosphate (cGMP) in brain and cerebrospinal fluid. PDE9A inhibition enhances synaptic plasticity and improves memory in preclinical cognition models, and prevents decreases in dendritic spine density in transgenic mice that overexpress amyloid precursor protein (APP) leading to high levels […]

Measuring the experience and perception of suffering

Purpose: assess psychometric properties of scales developed to assess experience and perception of physical, psychological, and existential suffering in older individuals.; Design and Methods: scales were administered to 3 populations of older persons and/or their family caregivers: individuals with Alzheimer’s disease (AD) and their family caregivers (N = 105 dyads), married couples in whom 1 […]

Validation study of the prototype of a disease-specific index measure for health-related quality of life in dementia

Background: Index measures for health-related quality of life (HRQoL) quantify the desirability (utility) of a certain health state. The commonly used generic index measure, e.g. EuroQol: EQ-5D, may underestimate relevant areas of specific diseases, resulting in lower validity. Disease-specific index measures on the other hand combine disease-specificity and quantification of perceived quality on several health […]

Glucose metabolism and PIB binding in carriers of a His163Tyr presenilin 1 mutation

Six young related pre-symptomatic carriers of a His163Tyr mutation in the presenilin 1 gene who will develop early onset familial Alzheimer’s disease (eoFAD), and a control group of 23 non-carriers underwent (18)F-fluorodeoxyglucose positron emission tomography (FDG PET). The mutation carriers were followed-up after 2 years. Multivariate analysis showed clear separation of carriers from non-carriers on […]

Treatment with cholinesterase inhibitors and memantine of patients in the Alzheimer’s Disease Neuroimaging Initiative

Objectives: To assess the clinical characteristics and course of patients with mild cognitive impairment (MCI) and mild Alzheimer disease (AD) treated with cholinesterase inhibitors (ChEIs) and memantine hydrochloride.; Design: Cohort study.; Setting: The 59 recruiting sites for the Alzheimer’s Disease Neuroimaging Initiative (ADNI).; Participants: Outpatients with MCI and AD in ADNI.; Main Outcome Measures: The […]

Cognitive rehabilitation multi-family group intervention for individuals with mild cognitive impairment and their care-partners

There is increasing need for early, pro-active programs that can delay dementia diagnosis and enhance well-being of individuals with mild cognitive impairment (MCI) and their care-partners (i.e., care-dyads). This randomized controlled trial evaluated the efficacy of a combined cognitive rehabilitation and multi-family group treatment (CR-MFG) that was designed to facilitate adoption of newly learned cognitive […]

Memantine for treatment of behavioural disturbances and psychotic symptoms in moderate to moderately severe Alzheimer dementia: a naturalistic study in outpatient services in Austria

We conducted an open, 16-week study on the efficacy of memantine on behavioral disturbances and psychotic symptoms in moderate to moderately severe Alzheimer s disease in daily routine. Fifty-three patients of 20 outpatient centers in Austria were recruited. The Neuropsychiatric Inventory (NPI) was defined as main outcome measure. After 16 weeks the total NPI score […]

Development and validation of the Inventory of Needs in Memory Impairment (BIG-65): illness-related needs in people with cognitive impairment and dementia

Background: There is growing evidence that individuals with cognitive impairment and dementia require systematic assessment of needs for the selection of optimal treatments. Currently no valid instrument is applicable for illness-related need assessment in this growing population.; Method: The purpose of this study was to develop and validate a new instrument (“Bedürfnisinventar bei Gedächtnisstörungen”, BIG-65) […]

Efficacy of a medical food in mild Alzheimer’s disease: A randomized, controlled trial

Objective: To investigate the effect of a medical food on cognitive function in people with mild Alzheimer’s disease (AD).; Methods: A total of 225 drug-naïve AD patients participated in this randomized, double-blind controlled trial. Patients were randomized to active product, Souvenaid, or a control drink, taken once-daily for 12 weeks. Primary outcome measures were the […]

Additional use of Aβ₄₂/Aβ₄₀ ratio with cerebrospinal fluid biomarkers P-tau and Aβ₄₂ increases the level of evidence of Alzheimer’s disease pathophysiological process in routine practice

Background: Cerebrospinal fluid (CSF) biomarkers have recently been included in the criteria for the diagnosis of Alzheimer’s disease (AD). Since interpretation of CSF profile requires the combination of three parameters, biological data are not always conclusive and isolated elevation of phosphorylated tau (P-tau) or reduction of amyloid-β (Aβ)42 alone can be observed. In these cases, […]
