Cognitive and psychiatric effects of vitamin B12 replacement in dementia with low serum B12 levels: a nursing home study
Background: The aim of this study is to determine whether B12 replacement would ameliorate cognitive and psychiatric symptoms in elderly subjects with dementia and low serum B12 levels.; Methods: A test group (n = 28) of nursing home residents with low serum B12 levels (300 pg/mL) were evaluated by blinded raters while the test group […]

Therapeutic conversation to improve mood in nursing home residents with Alzheimer’s disease
Few studies have tested strategies to address the mental health needs of individuals with Alzheimer’s disease (AD). To test a newly developed, empirically based modified counseling approach, 30 nursing home residents with AD were randomly assigned to a modified counseling (Therapeutic Conversation) treatment group or usual care control group. Mini-Mental State Examination mean scores were […]

Depression associated with dementia with Lewy bodies (DLB) and the effect of somatotherapy
Background: Dementia with Lewy bodies (DLB) is a common type of dementia. It is difficult to make an initial diagnosis of DLB because of a variety of early symptoms, including psychosis-like and depressive states. In this study, we examined the characteristic depressive symptoms of the prestage of DLB and the efficacy and safety of somatotherapy […]

A phase 2 multiple ascending dose trial of bapineuzumab in mild to moderate Alzheimer disease
Background: Bapineuzumab, a humanized anti-amyloid-beta (Abeta) monoclonal antibody for the potential treatment of Alzheimer disease (AD), was evaluated in a multiple ascending dose, safety, and efficacy study in mild to moderate AD.; Methods: The study enrolled 234 patients, randomly assigned to IV bapineuzumab or placebo in 4 dose cohorts (0.15, 0.5, 1.0, or 2.0 mg/kg). […]

Vascular care in patients with Alzheimer’s disease with cerebrovascular lesions-a randomized clinical trial
Objectives: To investigate whether vascular care slows dementia progression in patients with Alzheimer’s disease with cerebrovascular lesions on neuroimaging.; Design: Multicenter randomized controlled clinical trial with 2-year follow-up.; Setting: Neurological and geriatric outpatient clinics in 10 Dutch hospitals: three academic, five teaching, and two midsize community hospitals.; Participants: One hundred thirty community-dwelling patients with mild […]

Addenbrooke’s Cognitive Examination validation in Parkinson’s disease
Background: There is a clear need for brief, sensitive and specific cognitive screening instruments in Parkinson’s disease (PD).; Objectives: To study Addenbrooke’s Cognitive Examination (ACE) validity for cognitive assessment of PD patient’s using the Mattis Dementia Rating Scale (MDRS) as reference method. A specific scale for cognitive evaluation in PD, in this instance the Scales […]

Efficacy of a vitamin/nutriceutical formulation for moderate-stage to later-stage Alzheimer’s disease: a placebo-controlled pilot study
Recent studies demonstrated efficacy of a vitamin/ nutriceutical formulation (folate, vitamin B12, alpha-tocopherol, S-adenosyl methionine, N-acetyl cysteine, and acetyl-L-carnitine) for mild to moderate Alzheimer’s disease. Herein, we tested the efficacy of this formulation in a small cohort of 12 institutionalized patients diagnosed with moderate-stage to later-stage Alzheimer’s disease. Participants were randomly separated into treatment of […]

Methodological improvements in quantifying cognitive change in clinical trials: an example with single-dose administration of donepezil
Objectives: Change in cognitive function in response to a pharmacologic challenge can be observed with greater sensitivity by employing cognitive tests with optimal psychometric properties and a statistical approach that more accurately accounts for individual variability in performance. To demonstrate this approach we examined the cognitive effects of a single acute dose administration of an […]

Safety of lumbar puncture procedures in patients with Alzheimer’s disease
Changes in cerebrospinal fluid (CSF) biomarkers are representative of biochemical changes in the brain. Collection of CSF by lumbar puncture (LP) is essential for biomarker analysis, which is important for research in neurodegenerative disorders. However, LP for research purposes has been controversial due to a reported high incidence of severe LP headache when using standard […]

CSF biomarker profile and diagnostic value in vascular dementia
Background and Purpose: The differential diagnosis between vascular dementia (VD) and Alzheimer’s disease (AD) or mixed dementia (MD) is not always easy in clinical practice. The purpose of the present study was to evaluate the cerebrospinal fluid (CSF) biomarkers tau protein in its total (tau(T)) or hyperphosphorylated at threonin-181(tau(P-181)) form and beta amyloid peptide 1-42 […]
