OBJECTIVE To evaluate the safety, tolerability, and amyloid beta (Abeta) response to the gamma-secretase inhibitor LY450139 in Alzheimer disease. DESIGN Multicenter, randomized, double-blind, dose-escalation, placebo-controlled trial. SETTING Community-based clinical research centers. Patients Fifty-one individuals with mild to moderate Alzheimer(More)
Intermittent stimulation of striatal dopaminergic receptors seems to contribute to motor dysfunction in advanced Parkinson's disease (PD). With severe dopaminergic denervation, exogenous levodopa is largely decarboxylated to dopamine in serotonergic terminals. If 5-HT1A autoreceptors regulate dopamine as well as serotonin release, in parkinsonian patients(More)
Preserved cognitive performance is a key feature of successful aging. Several theoretical models have been proposed to explain the putative underlying relationship between brain function and performance. We aimed to review imaging studies of the association between brain functional response and cognitive performance among healthy younger and older adults to(More)
BACKGROUND Apolipoprotein E varepsilon4 (APOE varepsilon4) allele carrier status has been well established as a risk factor for developing Alzheimer's disease. However, the specific influence of APOE varepsilon4 allele status on cognitive and functional rates of decline in mild cognitive impairment (MCI) is poorly understood. We examine the prospective(More)
Reported benefits of various glutamatergic receptor antagonists in Parkinson's disease (PD) prompted an evaluation of the antidyskinetic effect of a putative glutamate release inhibitor in 15 moderately advanced patients. In a 3-week, double-blind, proof-of-concept study, riluzole (200 mg/day) failed to alter parkinsonian or levodopa-induced motor(More)
Stroke is the fourth leading cause of mortality in the United States, yet it is 80% preventable by addressing lifestyle factors including nutrition. Evaluating the impact of nutrition at the food group and dietary pattern level will provide greater insight into the role of nutrition in stroke. For this purpose, a review of the literature was conducted using(More)
Inpatient costs related to mental illness are substantial, though declining as a percentage of overall mental health treatment costs. The public sector has become increasingly involved in funding and providing mental health services. Nationwide Inpatient Sample data for the years 1999-2007 were used to: 1) examine Medicare, Medicaid, and private insurance(More)
OBJECTIVE The objective of this review was to elucidate the relationship between VaD and various nutritional factors based on epidemiological studies. BACKGROUND Vascular dementia (VaD) is the second most common type of dementia. The prevalence of VaD continues to increase as the US population continues to grow and age. Currently, control of potential(More)
BACKGROUND Dementia with Lewy bodies (DLB) is characterized neuropathologically by brainstem and cortical Lewy bodies and Lewy neurites, neuronal loss in brainstem nuclei, and Alzheimer disease (AD) pathology. Previous studies have suggested that spongiform change in the entorhinal cortex may also be a pathologic feature; however, this change has not been(More)
