BACKGROUND Mild cognitive impairment (MCI) and late-life depression are clinical syndromes that often co-occur and may represent an early manifestation of neurodegenerative disease. The present study examined white matter microstructure in patients with MCI with and without a history of major depression compared with healthy controls. METHODS Older adults with MCI and no history of major depr...
BACKGROUND Clinical subtypes of mild cognitive impairment (MCI) may represent different underlying aetiologies. METHODS This European, multicentre, memory clinic based study (DESCRIPA) of non-demented subjects investigated whether MCI subtypes have different brain correlates on MRI and whether the relation between subtypes and brain pathology is modified by age. Using visual rating scales, me...
Background: The value of the mandibulo-canine index (MCI) in gender identification has been proved in some studies in various countries. The goal of our study was to determine the utility of MCI in gender identification in Iran.Methods: This descriptional survey was performed on a group of 18- to 25-year-old Iranian students at the Tehran University of Medical Science. We included 50 males and ...
We analyse the relationship between nominal algebra and nominal rewriting, giving a new and concise presentation of equational deduction in nominal theories. With some new results, we characterise a subclass of equational theories for which nominal rewriting provides a complete and efficient procedure to check nominal algebra equality. This subclass includes specifications of lambda-calculus an...
Background: In this survey the absorbed dose by kidneys, bladder, liver and ovaries with 99mTc-EC (99mTc Ethylene dicysteine) renal scintigraphy was measured and compared with the absorbed dose from 99mTc-DTPA (99mTc - Dietheylne Triamine Penta-Acid), which often is used in renal scintigraphy.Methods: In this applicable study, we used a water phantom with geometrical sizes similar to that o...
BACKGROUND AND OBJECTIVE There are conflicting data relating homocysteine levels to the risk of Alzheimer's disease (AD). We sought to explore whether fasting plasma homocysteine is associated with the risk of mild cognitive impairment (MCI), an intermediate stage to dementia. METHODS Fasting levels of plasma homocysteine were obtained from 678 elderly subjects chosen at random from a cohort ...
There is increasing consensus regarding the importance of operationally defining and measuring functional decline in mild cognitive impairment (MCI). However, few studies have directly examined functional abilities in MCI or its presumed subtypes and, to date, reported findings have been discrepant. Nondemented older adults (n = 120) were administered a comprehensive cognitive battery measuring...
INTRODUCTION Reductions of cerebrospinal fluid (CSF) amyloid-beta (Aβ42) and elevated phosphorylated-tau (p-Tau) reflect in vivo Alzheimer's disease (AD) pathology and show utility in predicting conversion from mild cognitive impairment (MCI) to dementia. We investigated the P50 event-related potential component as a noninvasive biomarker of AD pathology in non-demented elderly. METHODS 36 MC...
