The obesity related gene, FTO, interacts with APOE, and is associated with Alzheimer’s disease risk: a prospective cohort study

The FTO gene has been shown to have a small but robust effect on body mass index (BMI) and to increase the risk for diabetes. Both high BMI and diabetes are vascular risk factors that might play a role in the development of Alzheimer’s disease (AD) and dementia. Thus, our aim was to explore the […]

Antihypertensive agents and risk of Parkinson’s disease, essential tremor and dementia: a population-based prospective study (NEDICES)

Background: Recent interest in antihypertensive agents, especially calcium channel blockers, has been sparked by the notion that these medications may be neuroprotective. A modest literature, with mixed results, has examined whether these medications might lower the odds or risk of Parkinson’s disease (PD) or dementia. There are no data for essential tremor (ET).; Objective: To […]

Atypical antipsychotic use and parkinsonism in dementia: effects of drug, dose, and sex

Background: Differences between atypical antipsychotics in their potential to cause parkinsonism and risk factors for antipsychotic-induced parkinsonism are not well established. There is a particular paucity of information on this in real-world use of these drugs, outside of clinical trial settings.; Objective: We compared the incidence of parkinsonism after new treatment with risperidone, olanzapine, or […]

Visual hallucinations and altered visual information processing in Parkinson disease and dementia with Lewy bodies

Visual hallucinations (VHs) are common in dementia with Lewy bodies (DLB) and Parkinson’s disease with dementia (PDD), while auditory hallucinations are rare. To neurophysiologically investigate the pathophysiology of VHs in these disorders, we studied event-related potentials (ERPs) of DLB, PDD, and Alzheimer’s disease (AD) patients. We compared visual and auditory ERP latencies among PDD patients […]

Visual evoked potentials to pattern, motion and cognitive stimuli in Alzheimer’s disease

The aim of our study was to verify reported visual dysfunctions of patients with Alzheimer disease with the use of several variants of VEPs and visual ERPs and to learn whether these methods can be useful in diagnostics of AD. We tested 15 patients (6 women and 9 men, aged from 58 to 87) with […]

Hospice use and outcomes in nursing home residents with advanced dementia

Objectives: To identify characteristics of nursing home (NH) residents with advanced dementia and their healthcare proxies (HCPs) associated with hospice referral and to examine the association between hospice use and the treatment of pain and dyspnea and unmet needs during the last 7 days of life.; Design: Prospective cohort study.; Setting: Twenty-two Boston-area NHs.; Participants: […]

Cued recall and other cognitive tasks to facilitate dementia recognition in primary care

Objectives: To compare the accuracy of commonly used tasks with that of the Visual Association Test (VAT), a conceptually different test involving cued recall of pictorial stimuli, in the recognition of dementia within primary care.; Design: A cross-sectional diagnostic study of concurrent validity.; Setting: Twenty-nine German primary care practices.; Participants: Four hundred twenty-three individuals in […]

Psychotropic medication use and cognition in institutionalized older adults with mild to moderate dementia

Background: Most studies examining psychotropic medication use on cognition in older persons with dementia include measures of global cognitive function. The present study examined the relationship between different types of psychotropic medication and specific cognitive functions in older people with dementia.; Methods: Two hundred and six institutionalized older adults with dementia (180 women, mean age […]

Combined evaluation of FDG-PET and MRI improves detection and differentiation of dementia

Introduction: Various biomarkers have been reported in recent literature regarding imaging abnormalities in different types of dementia. These biomarkers have helped to significantly improve early detection and also differentiation of various dementia syndromes. In this study, we systematically applied whole-brain and region-of-interest (ROI) based support vector machine classification separately and on combined information from different […]

Quality of life in nursing home residents with advanced dementia

Objectives: To examine quality of life (QOL) in nursing home (NH) residents with advanced dementia and identify correlates of QOL near the end of life.; Design: Cross-sectional data derived from NH records, interviews with residents’ surrogate decision-makers, QOL ratings by NH caregivers, and assessment of residents’ cognitive function.; Setting: Three NHs in Maryland.; Participants: A […]
