BACKGROUND To examine the discriminant validity of the Montreal Cognitive Assessment (MoCA) and the Mini-Mental State Examination (MMSE) in detecting patients with cognitive impairment at higher risk for dementia at a memory clinic setting. METHODS Memory clinic patients were administered the MoCA, MMSE, and a comprehensive formal neuropsychological battery. Mild cognitive impairment (MCI) su...
BACKGROUND AND PURPOSE Individuals with mild cognitive impairment (MCI) are at increased risk of Alzheimer's disease (AD) and probably other forms of dementia. Some subtypes of vascular dementia (VaD) may possess minor neuropathological changes of AD that may contribute to cognitive impairments. It was posited that MCI, identified by criteria described here, might present as a prodrome for VaD ...
OBJECTIVE To examine the long-term outcomes of community-based elderly African Americans by following their transitions from normal cognition to mild cognitive impairment (MCI) to dementia. METHODS Participants were from the community-based Indianapolis Dementia Project. A total of 4,104 African Americans were enrolled in 1992 or 2001 and followed until 2009 with regularly scheduled evaluatio...
BACKGROUND Cerebrovascular disease (CVD) may contribute to mild cognitive impairment (MCI). We sought to determine the relation of white matter hyperintensity (WMH) volume and infarcts in brain MRI to MCI in a community-based sample. METHODS A total of 679 elderly persons without dementia underwent brain MRI. WMH and infarcts were quantified using research methods. WMH was adjusted for total ...
Although both human epidemiologic and animal model studies have suggested that caffeine/coffee protects against Alzheimer's disease, direct human evidence for this premise has been lacking. In the present case-control study, two separate cohorts consisting of 124 total individuals (65-88 years old) were cognitively assessed and a blood sample taken for caffeine/biomarker analysis. Subjects were...
Cerebral spinal fluid (CSF) and structural imaging markers are suggested as biomarkers amended to existing diagnostic criteria of mild cognitive impairment (MCI) and Alzheimer's disease (AD). But there is no clear instruction on which markers should be used at which stage of dementia. This study aimed to first investigate associations of the CSF markers as well as volumes and shapes of the hipp...
این مقاله، در راستای تجمیع پولی ارائه شدهی بارنت (1984)، که تقاضای دو کارگزار مصرفکننده و تولیدکننده را درنظر میگرفت، فرمول جدیدی برای تجمیع روی داراییهای پولی تقاضاشده توسط مصرفکننده و بنگاه، شرکتهای دولتی و دولت ارائه میدهد. برای مدلسازی شرکتهای دولتی، از الگوی حداکثرسازی درآمد فروش بامول استفاده شده است. با حل مدل مشاهده شد که هزینهی استفاده از خدماتِ داراییهای پولی توسط شرکتهای د...
اقتصاددانان کینزی جدید نامتقارنی در زمینه سیاست پولی را به سه گروه تقسیمبندی میکنند: نامتقارنی در ارتباط با جهت اثرگذاری سیاست پولی (مثبت و منفی)، نامتقارنی مربوط به اندازه اثرگذاری سیاست پولی (بزرگ و کوچک) و نامتقارنی نسبت به موقعیت زمانی دورههای رکود و رونقی که سیاست پولی در آن‌ها اجرا می‌شود. پژوهش حاضر با تکیه بر گروه سوم نامتقارنیها به بررسی اثرات نامتقارن شکاف پولی بر تورم در رژیمه...
A new methodology for classification of MR images is proposed using a large data base (more than one thousand patient), for the classification of MCI patients, especially in the case of MCI-C and MCI-NC, using simultaneously all kind of features is proposed. An important goal in this paper is the identification and classification between normal subjects, MCI (Middle Cognitive Impairment) patien...
