Effect of cognitive training on the expression of brain-derived neurotrophic factor in lymphocytes of mild cognitive impairment patients

To identify biomarkers associated with cognitive stimulation of mild cognitive impairment (MCI) patients, we performed quantitative real-time reverse transcriptase polymerase chain reaction for brain-derived neurotrophic factor (BDNF) mRNA in peripheral lymphocytes of MCI and healthy subjects undergoing a multi-component cognitive training (CT) program. CT determined a significant decrease of BDNF mRNA levels in MCI (fold […]

Evidence for neurocognitive plasticity in at-risk older adults: the experience corps program

Objective: To determine whether Experience Corps (EC), a social service program, would improve age-vulnerable executive functions and increase activity in brain regions in a high-risk group through increased cognitive and physical activity.; Methods: Eight community-dwelling, older female volunteers and nine matched wait-list controls were recruited to serve in the ongoing EC: Baltimore program in three […]

Effect of TTP488 in patients with mild to moderate Alzheimer’s disease

Background: TTP488, an antagonist at the Receptor for Advanced Glycation End products, was evaluated as a potential treatment for patients with mild-to-moderate Alzheimer’s disease (AD). A previous report describes decreased decline in ADAS-cog (delta = 3.1, p = 0.008 at 18 months, ANCOVA with multiple imputation), relative to placebo, following a 5 mg/day dose of TTP488. Acute, reversible cognitive […]

Promoting health in early-stage dementia: evaluation of a 12-week course

This project tested a 12-week health promotion course for older adults with early-stage dementia. In a quasi-experimental design, participants were assigned by site to intervention group or control group and evaluated at two time points. Mini-Mental State Examination scores, Geriatric Depression Scale scores, health behaviors, plus several measures of psychological well-being were used in this […]

Collaborative care management reduces disparities in dementia care quality for caregivers with less education

Objectives: To examine educational gradients in dementia care and whether the effect of a dementia collaborative care management intervention varied according to the educational attainment of the informal caregiver.; Design: Analysis of data from a cluster-randomized controlled trial.; Setting: Eighteen clinics in three healthcare organizations in southern California.; Participants: Dyads of Medicare recipients aged 65 […]

The effects of counseling spouse caregivers of people with Alzheimer disease taking donepezil and of country of residence on rates of admission to nursing homes and mortality

Objective: Does psychosocial intervention for caregivers whose spouses with Alzheimer disease (AD) are taking donepezil delay nursing home (NH) placement or death of patients?; Design: Randomized controlled trial with 2 years of active treatment and up to 8.5 years of follow-up (mean: 5.4 years, SD: 2.4).; Setting: Outpatients of research clinics in Australia, the United […]

Effects of distraction and pictorial illustration on memory for countries in older adults with probable Alzheimer’s disease

Eight participants with probable Alzheimer’s disease (AD) were trained to recall names of countries using the spaced-retrieval memory intervention. Six training sessions were administered on alternate days over a 2-week period. Half of the participants studied a target country alone and the other half studied a target country along with eight distractor countries. Training stimuli […]

Neuropsychological criteria for mild cognitive impairment improves diagnostic precision, biomarker associations, and progression rates

We compared two methods of diagnosing mild cognitive impairment (MCI): conventional Petersen/Winblad criteria as operationalized by the Alzheimer’s Disease Neuroimaging Initiative (ADNI) and an actuarial neuropsychological method put forward by Jak and Bondi designed to balance sensitivity and reliability. 1,150 ADNI participants were diagnosed at baseline as cognitively normal (CN) or MCI via ADNI criteria […]

Yogic meditation reverses NF-κB and IRF-related transcriptome dynamics in leukocytes of family dementia caregivers in a randomized controlled trial

Background: Although yoga and meditation have been used for stress reduction with reported improvement in inflammation, little is known about the biological mechanisms mediating such effects. The present study examined if a yogic meditation might alter the activity of inflammatory and antiviral transcription control pathways that shape immune cell gene expression. Methods: Forty-five family dementia […]

Results of the citalopram to enhance cognition in Huntington disease trial

Background: The objective of this study was to evaluate citalopram for executive functioning in Huntington’s disease (HD).; Methods: The study was randomized, double-blind, and placebo-controlled. Thirty-three adults with HD, cognitive complaints, and no depression (Hamilton Depression [HAM-D] rating scale ≤ 12) were administered citalopram 20 mg or placebo (7 visits, 20 weeks), with practice and […]
