Impact of obstructive sleep apnea on cardiac organ damage in patients with acute ischemic stroke.

Background And Purpose: Both obstructive sleep apnea (OSA) and cardiac organ damage have a crucial role in acute ischemic stroke. Our aim is to explore the relationship between OSA and cardiac organ damage in acute stroke patients.

Methods: A total of 130 consecutive patients with acute ischemic stroke were enrolled.

Validation of a Neuro Virtual Reality-based version of the Multiple Errands Test for the assessment of executive functions.

The purpose of this study was to establish ecological validity and initial construct validity of the Virtual Reality (VR) version of the Multiple Errands Test (MET) (Shallice & Burgess, 1991; Fortin et al., 2003) based on the NeuroVR software as an assessment tool for executive functions. In particular, the MET is an assessment of executive functions in daily life, which consists of tasks that abide by certain rules and is performed in a shopping mall-like setting where items need to be bought and information needs to be obtained.

Implementation of the multiple errands test in a NeuroVR-supermarket: a possible approach.

Our goal was to develop a tool for the assessment of executive functions by customizing a virtual reality (VR) version of the Multiple Errands Test (MET) [Shallice & Burgess, 1991; Fortin et al., 2003]. The MET is an assessment of executive functions in daily life which consists of tasks that abide by certain rules.

A NeuroVR based tool for cognitive assessment and rehabilitation of post-stroke patients: two case studies.

Neuropsychological disorders are common in stroke patients, ranging from an isolated impairment to impairment in multiple cognitive functions. The cognitive domains affected are in particular executive functions. These comprise planning, organising, conducting, assessing and controlling actions.

Candidate gene analysis of IP-10 gene in patients with Alzheimer's disease.

Interferon-gamma-inducible Protein-10 (IP-10) is supposed to play a role in Alzheimer's disease (AD) development, as demonstrated by increased levels in cerebrospinal fluid from patients with AD. A mutation scanning of IP-10 exonic region was carried out in 10 patients with AD and 10 age-matched controls, demonstrating the presence of two previously reported single nucleotide polymorphisms (SNPs) in exon 4 (G-->C and T-->C) as well as a novel SNP in exon 2 (C-->T). Exon 4 G-->C and T-->C allelic variants were next evaluated in a population of 279 AD patients and 251 controls, in order to determine whether their presence could influence the susceptibility towards the development of the disease.

Serum MCP-1 levels are increased in mild cognitive impairment and mild Alzheimer's disease.

Upregulation of a number of chemokines, including monocyte chemotactic protein-1 (MCP-1), is associated with Alzheimer's disease (AD) pathological changes. Emerging evidence suggests that inflammatory events precede the clinical development of AD, as cytokine disregulation has been observed also in patients with mild cognitive impairment (MCI). MCP-1 levels were evaluated in serum samples from 48 subjects with MCI, 94 AD patients and 24 age-matched controls.
