Effects of telmisartan on cognition and regional cerebral blood flow in hypertensive patients with Alzheimer’s disease

Aim: Recent studies have shown that some antihypertensive medications are associated with a significant reduction in the incidence of Alzheimer’s disease (AD). However, it remains uncertain whether antihypertensive drugs may have a preventive effect on cognitive decline in patients with AD. We investigated the effects of telmisartan, an angiotensin II type 1 receptor blocker with […]

Mnemonic strategy training partially restores hippocampal activity in patients with mild cognitive impairment

Learning and memory deficits typify patients with mild cognitive impairment (MCI) and are generally attributed to medial temporal lobe dysfunction. Although the hippocampus is perhaps the most commonly studied neuroanatomical structure in these patients, there have been few attempts to identify rehabilitative interventions that facilitate its functioning. Here, we present results from a randomized, controlled, […]

Study protocol: EXERcise and cognition in sedentary adults with early-ONset dementia (EXERCISE-ON)

Background: Although the development of early-onset dementia is a radical and invalidating experience for both patient and family there are hardly any non-pharmacological studies that focus on this group of patients. One type of a non-pharmacological intervention that appears to have a beneficial effect on cognition in older persons without dementia and older persons at […]

Safety and biomarker effects of solanezumab in patients with Alzheimer’s disease

Objectives: To assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of 12 weekly infusions of solanezumab, an anti-β-amyloid (Aβ) antibody, in patients with mild-to-moderate Alzheimer’s disease. Cognitive measures were also obtained.; Methods: In this phase 2, randomized, double-blind, placebo-controlled clinical trial, 52 patients with Alzheimer’s disease received placebo or antibody (100 mg every 4 weeks, 100 […]

Improvement in delusions and hallucinations in patients with dementia with Lewy bodies upon administration of yokukansan, a traditional Japanese medicine

Background: This multicentre open-label trial examined the efficacy and safety of the traditional Japanese medicine, or Kampo medicine, yokukansan (YKS), for behavioural and psychological symptoms of dementia (BPSD) in patients with dementia with Lewy bodies.; Methods: Sixty-three dementia with Lewy bodies patients with probable BPSD (M:W, 30:33; mean age, 78.2±5.8 years) were enrolled and treated […]

Effect of six months of treatment with V0191 in patients with suspected prodromal Alzheimer’s disease

New criteria related to prodromal Alzheimer’s disease (AD) have been proposed to overcome the issue of heterogeneity of patients with mild cognitive impairment (MCI) and to better define patients in early stage AD. Only few therapeutic trials, if any, have been reported using this newly defined population. The objective of this study was to assess […]

Nicotine treatment of mild cognitive impairment: a 6-month double-blind pilot clinical trial

Objective: To preliminarily assess the safety and efficacy of transdermal nicotine therapy on cognitive performance and clinical status in subjects with mild cognitive impairment (MCI).; Methods: Nonsmoking subjects with amnestic MCI were randomized to transdermal nicotine (15 mg per day or placebo) for 6 months. Primary outcome variables were attentional improvement assessed with Connors Continuous […]

Cognitive stimulation in a-MCI: an experimental study

Nowadays, preventing the effects of mental decline is an international priority, but there is little research into cognitive training in mild cognitive impairment (MCI). We present the results of a program aimed at teaching memory strategies and improving metacognitive abilities. This was associated with training to ameliorate caregivers’ assistance. Two groups (A and B) were […]

A 12-week multidomain intervention versus active control to reduce risk of Alzheimer’s disease: study protocol for a randomized controlled trial

Background: Disappointing results from clinical trials of disease-modifying interventions for Alzheimer’s dementia (AD), along with reliable identification of modifiable risk factors in mid life from epidemiological studies, have contributed to calls to invest in risk-reduction interventions. It is also well known that AD-related pathological processes begin more than a decade before the development of clinical […]

Donepezil for dementia with Lewy bodies: a randomized, placebo-controlled trial

Objective: Because cholinergic deficits are prominent in dementia with Lewy bodies (DLB), we investigated the effects of a cholinesterase inhibitor, donepezil, in such patients in a randomized, double-blind, placebo-controlled exploratory phase 2 trial.; Methods: One-hundred forty patients with DLB, recruited from 48 specialty centers in Japan, were randomly assigned to receive placebo or 3, 5, […]
