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 […]

Safety and tolerability of rivastigmine transdermal patch compared with rivastigmine capsules in patients switched from donepezil: data from three clinical trials
Objectives: To compare the safety and tolerability of switching patients with mild-to-moderate Alzheimer’s disease from donepezil to either rivastigmine capsule or transdermal patch.; Methods: Three studies investigated the switch from donepezil to rivastigmine; study US13 was a 26-week, single-arm, immediate-switch study; US18 was a 26-week, sequential cohort study (both studies evaluated rivastigmine capsules 3-12 mg/day); […]

Evaluating the cognitive effects of donepezil 23 mg/d in moderate and severe Alzheimer’s disease: analysis of effects of baseline features on treatment response
Background: Treatment of Alzheimer’s disease with acetylcholinesterase inhibitors can result in symptomatic benefits, but patients often show variable responses. The objective of this post hoc analysis was to investigate relationships between easily identifiable baseline characteristics/demographics and cognitive response in patients treated with either donepezil 23 mg/d or 10 mg/d and to identify factors potentially influencing response.; Methods: […]

PRECREST: a phase II prevention and biomarker trial of creatine in at-risk Huntington disease
Objective: To assess the safety and tolerability of high-dose creatine, the feasibility of enrolling premanifest and 50% at-risk subjects in a prevention trial, and the potential of cognitive, imaging, and blood markers.; Methods: Sixty-four eligible consenting participants were randomly allocated (1:1) to 15 g twice daily of creatine monohydrate or placebo for a 6-month double-blind […]

Psychotropic drug consumption at admission and discharge of nursing home residents
Objectives: To quantify transitions of residents into or out of nursing homes (NHs) and to describe psychotropic drug prescription at admission and discharge and with regard to dementia diagnosis.; Design: A descriptive, cross-sectional, noninterventional study.; Setting: The setting included 300 NH in France.; Participants: Participants included 2231 NH residents.; Measurements: Participants reported the number, origin, […]

Individual music therapy for agitation in dementia: an exploratory randomized controlled trial
Objectives: Agitation in nursing home residents with dementia leads to increase in psychotropic medication, decrease in quality of life, and to patient distress and caregiver burden. Music therapy has previously been found effective in treatment of agitation in dementia care but studies have been methodologically insufficient. The aim of this study was to examine the […]

Increased pulse pressure linked to dementia: further results from the Hypertension in the Very Elderly Trial – HYVET
Objectives: High blood pressure (BP) has been associated with increased risk of dementia. Concerns have been raised about lowering BP too far in the very elderly and thereby increasing risk. There is some evidence to suggest a potential ‘J’-shaped relationship between DBP and risk of cognitive impairment. This was investigated using data from the HYpertension […]

A randomized, controlled cross-over trial of dermally-applied lavender (Lavandula angustifolia) oil as a treatment of agitated behaviour in dementia
Background: Lavender essential oil shows evidence of sedative properties in neurophysiological and animal studies but clinical trials of its effectiveness as a treatment of agitation in people with dementia have shown mixed results. Study methods have varied widely, however, making comparisons hazardous. To help remedy previous methodological shortcomings, we delivered high grade lavender oil in […]

The safety, tolerability, pharmacokinetics and cognitive effects of GSK239512, a selective histamine H₃ receptor antagonist in patients with mild to moderate Alzheimer’s disease: a preliminary investigation
Background: The histamine H3 receptor plays a critical role in the negative neuromodulation of neurotransmitters involved in cognitive function. H3 receptor antagonists/inverse agonists have been shown to exert pro-cognitive effects in pre-clinical models. GSK239512 is a potent and selective H₃ receptor antagonist developed for the treatment of cognitive dysfunction in neurodegenerative disorders. In this study […]

Dopamine D₂-agonist rotigotine effects on cortical excitability and central cholinergic transmission in Alzheimer’s disease patients
Dopamine is a neurotransmitter involved in several brain functions ranging from emotions control, movement organization to memory formation. It is also involved in the regulation of mechanisms of synaptic plasticity. However, its role in Alzheimer’s disease (AD) pathogenesis is still puzzling. Several recent line of research instead indicates a clear role for dopamine in both […]
