OBJECTIVES Little is known about the longitudinal effects of training programs on family caregivers' health-related quality of life (HRQoL) and depressive symptoms over time. Therefore, the purpose of this study was to examine the effects of a home-based caregiver training program on HRQoL and depressive symptoms for family caregivers of older persons with(More)
BACKGROUND The underlying change of gene network expression of Guillain-Barré syndrome (GBS) remains elusive. We sought to identify GBS-associated gene networks and signaling pathways by analyzing the transcriptional profile of leukocytes in the patients with GBS. METHODS AND FINDINGS Quantitative global gene expression microarray analysis of peripheral(More)
BACKGROUND To compare the neocortical amyloid loads among cognitively normal (CN), amnestic mild cognitive impairment (aMCI), and Alzheimer's disease (AD) subjects with [(18)F]AV-45 positron emission tomography (PET). MATERIALS AND METHODS [(18)F]AV-45 PET was performed in 11 CN, 13 aMCI, and 12 AD subjects to compare the cerebral cortex-to-whole(More)
PPP2R2B, a protein widely expressed in neurons throughout the brain, regulates the protein phosphatase 2A (PP2A) activity for the microtubule-associated protein tau and other substrates. Altered PP2A activity has been implicated in spinocerebellar ataxia 12, Alzheimer's disease (AD), and other tauopathies. Through a case-control study and a reporter assay,(More)
In this study, an MRI-based classification framework was proposed to distinguish the patients with AD and MCI from normal participants by using multiple features and different classifiers. First, we extracted features (volume and shape) from MRI data by using a series of image processing steps. Subsequently, we applied principal component analysis (PCA) to(More)
RATIONALE AND OBJECTIVES The primary objective of the current investigation was to characterize white matter integrity in different subtypes of mild cognitive impairment (MCI) using tract-based spatial statistics of diffusion tensor imaging. MATERIALS AND METHODS The study participants were divided into 4 groups of 30 subjects each as follows: cognitively(More)
Prostaglandin D(2) synthase (PGDS) is the most abundant brain protein in cerebrospinal fluid (CSF) and is tied closely with inflammatory processes. This study investigated whether CSF PGDS levels in patients with acute inflammatory demyelinating polyneuropathy (AIDP) are altered. The results suggest that PGDS concentration is significantly increased in the(More)
To identify subclinical autonomic dysfunction in mild Guillain-Barré syndrome (GBS), a set of autonomic function tests was serially performed for up to 6 months in 5 GBS patients with mild disability at the nadir. Parasympathetic autonomic function tests consisted of Valsalva ratio and R-R interval variation during rest and deep breathing. Sympathetic(More)
PURPOSE In addition to testing blood, cerebrospinal fluid (CSF) has been analyzed in the search for biomarkers. The aim of this study was to identify biomarkers in CSF for neuropsychological symptoms in early-stage late-onset Alzheimer's disease (LOAD). METHODS CSF levels of beta-amyloid 1-42 (Aβ42), F2-isoprostanes (F2-IsoPs) and F4-neuroprostanes(More)
