White-matter vascular lesions correlate with alpha EEG sources in mild cognitive impairment.
It is an open issue if vascular and Alzheimer's disease (AD) lesions represent additive factors in the development of mild cognitive impairment (MCI), as a preclinical stage of Alzheimer's disease (AD) at group level. In the present study, we tested the hypothesis that electroencephalographic (EEG) alpha rhythms, which are affected (i.e. decreased in amplitude) by AD processes, are relatively p...
متن کاملWhite matter hyperintensities, executive function and global cognitive performance in vascular mild cognitive impairment.
UNLABELLED Vascular mild cognitive impairment (VaMCI) represents an early symptomatic stage of vascular cognitive impairment and might be associated to fronto-executive dysfunction. METHODS Twenty-six individuals (age: 73.11±7.90 years; 65.4% female; schooling: 9.84±3.61 years) were selected through neuropsychological assessment and neuroimaging. Clinical and neuroimaging data of VaMCI indivi...
متن کاملVascular risk factors and white matter hyperintensities in patients with amnestic mild cognitive impairment.
BACKGROUND Subjects affected by aMCI are considered at high risk for AD. Nevertheless, the role of both vascular risk factors and WMH is matter of debate. PATIENTS AND METHODS We enrolled consecutively 21 aMCI subjects according to Petersen Criteria; the study included routine screening for dementia, neuropsychological evaluation and brain MRI. Six vascular risk factors were assessed and WMH ...
متن کاملThe Correlation of the White Matter Lesions and Lacunar Infarcts in Patients with Vascular Cognitive Impairment
Department of Neurology, Asan Medical Center, University of Ulsan College of Medicine, Seoul; Department of Neurosurgery*, Seoul National University College of Medicine, Seongnam, Korea Background: Cerebral white matter lesions (WMLs) and lacunar infarcts (LIs) are mostly caused by small vessel disease (SVD). Whereas the main pathomechanism behind LIs is SVD, a variety of mechanisms could be re...
متن کاملproton magnetic resonance spectroscopy and cognitive impairment in patients with ischemic white matter lesions
background: the purpose of this study is to investigate the relationship between the cognitive impairment and naa/cr and cho/cr ratios in the proton magnetic resonance spectroscopy (1hmrs), and to assess the importance of 1hmrs in the early diagnosis of cognitive impairment in patients with ischemic white matter lesions (wmls). materials and methods: a total of 45 patients (23males and 22 femal...
