BACKGROUND AND PURPOSE It is particularly difficult to differentiate dementia with Lewy bodies (DLB) from the related dementias of Alzheimer's disease (AD) and Parkinson's disease dementia (PDD). Few studies have been designed to comparatively analyze detailed neuropsychological assessments of DLB patients and patients with AD and PDD. METHODS THREE GROUPS OF PATIENTS PARTICIPATED IN THIS STU...

OBJECTIVES We hypothesized an impaired renal endocrine and natriuretic response to volume expansion (VE) in humans with pre-clinical systolic dysfunction (PSD) and pre-clinical diastolic dysfunction (PDD). We further hypothesized that exogenous B-type natriuretic peptide (BNP) could rescue an impaired natriuretic response in PSD and PDD. BACKGROUND Recent reports suggest that in early systoli...

IMPORTANCE Epidemiologic data on dementia with Lewy bodies (DLB) and Parkinson disease dementia (PDD) remain limited in the United States and worldwide. These data are essential to guide research and clinical or public health interventions. OBJECTIVE To investigate the incidence of DLB among residents of Olmsted County, Minnesota, and compare it with the incidence of PDD. DESIGN The medical...

Background and objective: Agro-healing (care farming) has developed into a new professional area belonging to the field of social horticulture. programs are horticultural activities that serve as rehabilitation training for therapeutic treatment physical mental disorders, have caught attention scholars in medicine psychology. Developmental disabilities reduce cognitive function; people with dev...

The proportional diierentiation model provides the network operator with thètuning knobs' for adjusting the per-hop QoS ratios between classes, independent of the class loads. This paper applies the proportional model in the diierentiation of queueing delays, and investigates appropriate packet scheduling mechanisms. The second part of this work 2] considers the corresponding loss rate diierent...

OBJECTIVE To quantify visual discrimination, space-motion, and object-form perception in patients with Parkinson disease dementia (PDD), dementia with Lewy bodies (DLB), and Alzheimer disease (AD). METHODS The authors used a cross-sectional study to compare three demented groups matched for overall dementia severity (PDD: n = 24; DLB: n = 20; AD: n = 23) and two age-, sex-, and education-matc...

Parkinson's disease (PD) related dementia (PDD) develops in up to 80% of PD patients. The present study was performed to further unravel the underlying pathophysiological mechanisms by applying a new analysis approach that uses an atlas-based MEG beamformer to provide a detailed anatomical mapping of cortical rhythms and functional interactions. Importantly, we used the phase lag index (PLI) as...

cis- and trans-diamminedichloroplatinum(II) (PDD) produced a DNA cross-linking effect in mouse leukemia L1210 cells, which was demonstrable after subtoxic treatments with the DNA alkaline elution technique. Cross-linking effects developed following treatments with concentrations as low as 1 micron for cis-PDD and 5 micron for trans-PDD, which permitted over 80% survival of colony-forming abilit...

Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis and this is characterized by asymptomatic soft tissue swelling that affects the lateral aspects of the proximal interphalangeal (PIP) joints of the fingers. Although the etiology of PDD is unknown, the possibility of repetitive minor trauma by habitual or compulsive habits of interlacing the fingers or rubbing of the fingers...

BACKGROUND AND PURPOSE Previous studies on the clinical and pathological manifestations of Parkinson's disease dementia (PDD) have reported findings more similar to dementia with Lewy bodies (DLB) than to Alzheimer's disease (AD). The aim of this study was to investigate the neuropsychiatric symptoms of PDD compared to DLB and AD. METHODS We conducted a retrospective case-control study on 125...
