Longitudinal medication usage in Alzheimer disease patients

This study examined in detail patterns of cholinesterase inhibitors (ChEIs) and memantine use and explored the relationship between patient characteristics and such use. Patients with probable Alzheimer disease AD (n=201) were recruited from the Predictors Study in 3 academic AD centers and followed from early disease stages for up to 6 years. Random effects logistic […]

Vitamins B₁₂, B₆, and folic acid for cognition in older men

[Correction Notice: An erratum for this article was reported in Vol 77(8) of Neurology (see record [rid]2011-21984-022[/rid]). In the original article, the daily dose of vitamin B12 used in the trial was reported as 400 μg, but it should have been 500 μg.] Objective: To investigate whether supplementing older men with vitamins B12, B6, and […]

Treatment of vascular risk factors is associated with slower decline in Alzheimer disease

Background: There is growing evidence that vascular risk factors (VRF) contribute to cognitive decline. Whether their treatment can slow down the progression of Alzheimer disease (AD) remains unsettled. The aim of this observational study was to evaluate whether the treatment of VRF is associated with a slower cognitive decline in patients who have AD without […]

Randomized trial of deep brain stimulation for Parkinson disease: thirty-six-month outcomes

Objectives: Our objective was to compare long-term outcomes of deep brain stimulation (DBS) of the globus pallidus interna (GPi) and subthalamic nucleus (STN) for patients with Parkinson disease (PD) in a multicenter randomized controlled trial.; Methods: Patients randomly assigned to GPi (n = 89) or STN DBS (n = 70) were followed for 36 months. […]

The effects of cognitive speed of processing training among older adults with psychometrically- defined mild cognitive impairment

Despite the growing interest in cognitive training programs as a potential non-pharmacological approach to slowing cognitive decline in mild cognitive impairment (MCI), there has been little research on the differential effectiveness of training among subtypes of MCI (i.e., amnestic, single non-amnestic, and multi-domain). The current study examined the longitudinal effects of cognitive speed of processing […]

Adherence to exercise programs and determinants of maintenance in older adults with mild cognitive impairment

After a randomized controlled trial showing that improvement on some aspects of cognitive function was related to adherence to an exercise program, determinants of adherence and maintenance were further studied. Older adults with mild cognitive impairment were contacted 6 mo after the end of exercise programs for a telephone interview addressing patterns of adherence and […]

Hormone levels and cognitive function in postmenopausal midlife women

Gonadal hormones may influence cognitive function. Postmenopausal midlife women in the population-based Melbourne Women’s Midlife Health Project cohort were administered a comprehensive battery of neuropsychological tests on two occasions 2 years apart. Participants (n = 148, mean age 60 years) had undergone natural menopause and were not using hormone therapy. Estrone, total and free estradiol, […]

The effect of HMG-CoA reductase inhibitors on cognition in patients with Alzheimer’s dementia: a prospective withdrawal and rechallenge pilot study

Background: Statins are well-known for their cardiovascular benefits. However, the cognitive effects of statins are not well understood. We hypothesized that individuals with preexisting dementia would be more vulnerable to statin-related cognitive effects.; Objective: The aim of this study was to evaluate the impact on cognition of 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor (statin) discontinuation and rechallenge […]

Relapse risk after discontinuation of risperidone in Alzheimer’s disease

Background: Among patients with Alzheimer’s disease who have had a response to antipsychotic medication for psychosis or agitation-aggression, the risk of a recurrence of symptoms after discontinuation of the medication has not been established.; Methods: Patients with Alzheimer’s disease and psychosis or agitation-aggression received open-label treatment with risperidone for 16 weeks. Those who had a […]

Effectiveness of family meetings for family caregivers on delaying time to nursing home placement of dementia patients: a randomized trial

Background: Interventions relieving the burden of caregiving may postpone or prevent patient institutionalization. The objective of this study was to determine whether a family meetings intervention was superior to usual care in postponing nursing home placement of patients with dementia.; Methods: A randomized multicenter trial was conducted among 192 patients with a clinical diagnosis of […]
