Aim: Determine whether patients with Alzheimer’s disease demonstrating functional and cognitive decline, following 24-48 weeks of open-label treatment with 9.5 mg/24 h (10 cm(2)) rivastigmine patch, benefit from a dose increase in a double-blind (DB) comparative trial of two patch doses.; Methods: Patients meeting prespecified decline criteria were randomized to receive 9.5 or 13.3 mg/24 […]
The Mental Activity and eXercise (MAX) trial: a randomized controlled trial to enhance cognitive function in older adults

Yaffe, Kristine
Importance: The prevalence of cognitive impairment and dementia are projected to rise dramatically during the next 40 years, and strategies for maintaining cognitive function with age are critically needed. Physical or mental activity alone result in relatively small, domain-specific improvements in cognitive function in older adults; combined interventions may have more global effects.; Objective: To […]

Objective: To evaluate whether antioxidant supplements presumed to target specific cellular compartments affected cerebrospinal fluid (CSF) biomarkers.; Design: Double-blind, placebo-controlled clinical trial.; Setting: Academic medical centers.; Participants: Subjects with mild to moderate Alzheimer disease.; Intervention: Random assignment to treatment for 16 weeks with 800 IU/d of vitamin E (α-tocopherol) plus 500 mg/d of vitamin C […]
Pilot randomized controlled study of a histamine receptor inverse agonist in the symptomatic treatment of AD

We performed a clinical trial to evaluate the effects of the histamine subtype-3 receptor inverse agonist MK- 0249 on cognition in AD patients. Mild-to-moderate AD patients were randomized 1:1 to 4 weeks of double-blind daily treatment with oral MK-0249 5-mg or placebo. Pharmacokinetic and PET data suggested that MK-0249 5-mg daily would achieve approximately 85% […]

Background: Approximately 40% of hospitalized older adults have cognitive impairment (CI) and are more prone to hospital-acquired complications. The Institute of Medicine suggests using health information technology to improve the overall safety and quality of the health care system.; Objective: Evaluate the efficacy of a clinical decision support system (CDSS) to improve the quality of […]
Preventing loss of independence through exercise (PLIE): a pilot clinical trial in older adults with dementia
Barnes, D. E.,
Mehling, W.,
Wu, E.,
Beristianos, M.,
Yaffe, K.,
Skultety, K.,
Chesney, M. A.
BACKGROUND: Current dementia medications have small effect sizes, many adverse effects and do not change the disease course. Therefore, it is critically important to study alternative treatment strategies. The goal of this study was to pilot-test a novel, integrative group exercise program for individuals with mild-to-moderate dementia called Preventing Loss of Independence through Exercise (PLIE), […]
Preventing Loss of Independence through Exercise (PLIE): qualitative analysis of a clinical trial in older adults with dementia
Wu, E.,
Barnes, D. E.,
Ackerman, S. L.,
Lee, J.,
Chesney, M.,
Mehling, W. E.
OBJECTIVES: Preventing Loss of Independence through Exercise (PLIE) is a novel, integrative exercise program for individuals with dementia that combines elements of different conventional and complementary exercise modalities (e.g. tai-chi, yoga, Feldenkrais, and dance movement therapy) and focuses on training procedural memory for basic functional movements (e.g., sit-to-stand) while increasing mindful body awareness and facilitating […]

Combination antiretroviral therapy (CART) has greatly reduced medical morbidity and mortality with HIV infection, but high rates of HIV-associated neurocognitive disorders (HAND) continue to be reported. Because large HIV-infected (HIV+) and uninfected (HIV-) groups have not been studied with similar methods in the pre-CART and CART eras, it is unclear whether CART has changed the […]
