Effects of Chinese medicine for tonifying the kidney and resolving phlegm and blood stasis in treating patients with amnestic mild cognitive impairment: a randomized, double-blind and parallel-controlled trial

Background: It is important to detect and prevent Alzheimer disease (AD) at its early stage. Constituting the early stage sign of AD, amnestic mild cognitive impairment (aMCI) has drawn much attention. Studies have shown that donepezil could reduce the AD assessment scale-cognitive subscale (ADAS-Cog) score in MCI patients and improve the patient’s attention and speed […]

The effects of ramipril in individuals at risk for Alzheimer’s disease: results of a pilot clinical trial

Research shows that certain antihypertensives taken during midlife confer Alzheimer’s disease (AD) related benefits in later life. We conducted a clinical trial to evaluate the extent to which the angiotensin converting enzyme inhibitor (ACE-I), ramipril, affects AD biomarkers including cerebrospinal fluid (CSF) amyloid-β (Aβ) levels and ACE activity, arterial function, and cognition in participants with […]

Study of the effects of vinpocetin on cognitive functions

Introduction: Chronic cerebral hypoperfusion is a risk factor for the development of certain types of dementia. Mild cognitive impairment is a stage of predementia condition, because the symptoms are similar but not as severe as the symptoms in patients with dementia. Vinpocetine, due to its complex mechanism of action, has an important role in the […]

Effectiveness of a condensed protocol for disclosing APOE genotype and providing risk education for Alzheimer disease

Purpose: Brief, effective models of patient genetic education are needed for common, complex diseases. Using Alzheimer disease as a model, we compared participants’ risk knowledge and recall in extended versus condensed education protocols.; Methods: A four-site randomized clinical trial enrolled 280 first-degree relatives of individuals with Alzheimer disease (mean age = 58 years, 71% female); […]

Amyloid-β(1-15/16) as a marker for γ-secretase inhibition in Alzheimer’s disease

Amyloid-β (Aβ) producing enzymes are key targets for disease-modifying Alzheimer’s disease (AD) therapies since Aβ trafficking is at the core of AD pathogenesis. Development of such drugs might benefit from the identification of markers indicating in vivo drug effects in the central nervous system. We have previously shown that Aβ(1-15) is produced by concerted β-and […]

Alzheimer’s disease: is pacemaker implantation safe?

Aim: To evaluate the safety of pacemaker implantation in patients with Alzheimer’s disease (AD).; Methods: We reviewed all cases admitted to our institution between January 2008 and June 2009, with symptomatic bradyarrhythmia for whom a permanent pacemaker was implanted. Beginning in June 2009, we prospectively collected data from all patients with the same diagnosis and […]

The impact of different types of assistive devices on gait measures and safety in Huntington’s disease

Background: Gait and balance impairments lead to frequent falls and injuries in individuals with Huntington’s disease (HD). Assistive devices (ADs) such as canes and walkers are often prescribed to prevent falls, but their efficacy is unknown. We systematically examined the effects of different types of ADs on quantitative gait measures during walking in a straight […]

The use of Internet technology for psychoeducation and support with dementia caregivers

A large randomized trial evaluated the benefits of online education, support, and self-care promotion for caregivers of persons with dementia. Anecdotal reports from participants indicated enjoyment of the materials, convenient access from home, and support from professionals and other caregivers. A substantial number of screened caregivers experienced obstacles of access, cost, and time regarding use […]

A proteomics study reveals a predominant change in MaoB expression in platelets of healthy volunteers after high protein meat diet: relationship to the methylation cycle

Studies investigating the impact of high meat intake on cognition have yielded contradictory results as some show improved cognitive performance, whereas others report an increase of risk factors for dementia. However, few studies were designed to directly assess the effect of a high protein (HP) diet on both cognitive performance and corresponding biochemical parameters. A […]

DHEA and cognition in HIV-positive patients with non-major depression

Background: Dihydroepiandrosterone (DHEA) has been investigated for its potential role in improving cognition in a number of patient populations. Treatment options are limited for HIV-associated neurocognitive disorders.; Objective: The authors tested the effect of DHEA administration on the cognitive functioning of HIV-positive subjects with non-major depression.; Method: The neuropsychological testing data for 60 HIV-positive patients […]
