Resonance in thalamocortical networks is critically involved in sculpting oscillatory behavior in large ensembles of neocortical cells. Neocortical oscillations provide critical information about the integrity of thalamocortical circuits and functional connectivity of cortical networks, which seem to be significantly disrupted by the neuronal death and(More)
BACKGROUND Discerning dementia with Lewy bodies (DLB) from Alzheimer's disease (AD) is one of the most common and challenging differential diagnoses at the memory clinic. Although the neuropsychiatric manifestations have been widely reported as one of the main key points in the differential diagnosis between these two diseases, to date no neuropsychiatric(More)
OBJECTIVES To analyse the differences in the clinical features and characteristics of (123)I-labelled 2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl) nortropane ((123)I-FP-CIT) single photon emission CT (SPECT) imaging among patients with vascular parkinsonism (VP) and Parkinson's disease (PD). METHODS We performed a case-control study to compare(More)
Growing evidence suggests that decreased functional connectivity in cortical networks precedes clinical stages of Alzheimer’s disease (AD), although our knowledge about cerebral and biological correlates of this phenomenon is limited. To shed light on this issue, we have investigated whether resting-state oscillatory connectivity patterns in healthy older(More)
PURPOSE The study's objective was to develop diagnostic predictive models using data from two commonly used [(123)I]FP-CIT SPECT assessment methods: region-of-interest (ROI) analysis and whole-brain voxel-based analysis. METHODS We included retrospectively 80 patients with vascular parkinsonism (VP) and 164 patients with Parkinson's disease (PD) who(More)
INTRODUCTION There is a strong association between the e4 allele of apolipoprotein E (APOE) and Alzheimer's disease (AD). This converts this allele into a risk factor for the development of AD. The association between APOE4 and dementia with Lewy bodies (DLB) is under discussion. In DLB, the presence of APOE4 has been related with a greater amount of senile(More)
Functional Neuroimaging has been traditionally used in research for patients with different Parkinsonian syndromes. However, the emergence of commercial radiotracers together with the availability of single photon emission computed tomography (SPECT) and, more recently, positron emission tomography (PET) have made them available for clinical practice.(More)
