Effects of donepezil, galantamine and rivastigmine in 938 Italian patients with Alzheimer’s disease: a prospective, observational study
Acetylcholinesterase inhibitors (AChEIs) have been used to improve cognitive status and disability in patients with mild to moderate Alzheimer’s disease (AD). However, while the efficacy of AChEIs (i.e. how they act in randomized controlled trials) in this setting is widely accepted, their effectiveness (i.e. how they behave in the real world) remains controversial. To compare […]

Safety and tolerability of rivastigmine capsule with memantine in patients with probable Alzheimer’s disease: a 26-week, open-label, prospective trial (Study ENA713B US32)
Objective: Rivastigmine, a dual cholinesterase inhibitor (ChEI), is widely approved for the symptomatic treatment of both mild-to-moderate Alzheimer’s disease (AD) and Parkinson’s disease dementia. Orally administered ChEIs may be associated with gastrointestinal (GI) side effects and add-on therapy with memantine, an N-methyl-d-aspartate receptor antagonist, approved for moderate-to-severe AD, may ameliorate such side effects. This was […]

Psychotropic medication use and cognition in institutionalized older adults with mild to moderate dementia
Background: Most studies examining psychotropic medication use on cognition in older persons with dementia include measures of global cognitive function. The present study examined the relationship between different types of psychotropic medication and specific cognitive functions in older people with dementia.; Methods: Two hundred and six institutionalized older adults with dementia (180 women, mean age […]

Long-term follow-up of patients immunized with AN1792: reduced functional decline in antibody responders
Background: Immunization of patients with Alzheimer’s disease (AD) with synthetic amyloid-beta peptide (Abeta(42)) (AN1792) was previously studied in a randomized, double-blind, placebo-controlled phase 2a clinical trial, Study AN1792(QS-21)-201. Treatment was discontinued following reports of encephalitis. One year follow-up revealed that AN1792 antibody responders showed improvements in cognitive measures as assessed by the neuropsychological test battery […]

Effect of tramiprosate in patients with mild-to-moderate Alzheimer’s disease: exploratory analyses of the MRI sub-group of the Alphase study
Objectives: The efficacy, safety and disease-modification of tramiprosate (homotaurine)were investigated in a recently completed large-scale Phase III clinical study in patients with mild to moderate Alzheimer’s disease (AD), the Alphase study. Disease-modification was assessed using longitudinal volumetric MRI (vMRI) measurements of the hippocampus in a subgroup of patients. The present study describes the vMRI, cognitive […]

A randomized double-blind trial of the effects of hormone therapy on delayed verbal recall in older women
We examined whether estradiol and norethindrone hormone therapy (HT) prevented decline in delayed verbal recall in older women with normal to mildly impaired memory functioning. This was a 2-year, randomized, double-blind, placebo-controlled trial of 142 women aged 61-87, randomly assigned to receive 1 mg 17-beta estradiol daily and 0.35 mg norethindrone 3 days/week or daily […]

Vitamins B(12), B(6), and folic acid for cognition in older men
Objective: To investigate whether supplementing older men with vitamins B(12), B(6), and folic acid improves cognitive function.; Methods: The investigators recruited 299 community-representative hypertensive men 75 years and older to a randomized, double-blind controlled clinical trial of folic acid, vitamin B(6), and B(12) supplementation vs placebo over 2 years. The primary outcome of interest was […]

Safety and efficacy of galantamine (Reminyl) in severe Alzheimer’s disease (the SERAD study): a randomised, placebo-controlled, double-blind trial
Background: The efficacy of galantamine has been shown in patients with mild, moderate, and advanced moderate Alzheimer’s disease (AD). Here we report its efficacy in patients with severe AD.; Methods: Between December, 2003, and March, 2007, patients aged 84 (SD 6) years with severe AD (mini-mental state examination [MMSE] score 5-12 points), in a nursing […]

A randomized, placebo-controlled trial of latrepirdine in Huntington disease
Objectives: To evaluate the safety and tolerability of latrepirdine in Huntington disease (HD) and explore its effects on cognition, behavior, and motor symptoms.; Design: Double-blind, randomized, placebo-controlled trial.; Setting: Multicenter outpatient trial.; Participants: Ninety-one participants with mild to moderate HD enrolled at 17 US and UK centers from July 18, 2007, through July 16, 2008.; […]

Efficacy of akatinol memantine in moderate cognitive impairments
A six-month open clinical trial of the efficacy of Akatinol was conducted in 40 patients with moderate cognitive impairments (MCI) using piracetam (20 patients) as reference agent; mean age was 67.7 +/- 7.2 years. Patient status was evaluated using a number of scales, questionnaires, and neuropsychological tests prior to treatment and at three and six […]
