Our aim in this study was to explore the neural substrates of executive function in frontal and nonfrontal white matter using diffusion tensor imaging (DTI). We studied the relationship between executive dysfunction and DTI measurements on 13 subjects with amnesic mild cognitive impairment (aMCI), 11 subjects with early Alzheimer's disease (AD), and 16(More)
The purpose of this paper is to integrate the technologies of radio frequency identification, global positioning system, global system for mobile communications, and geographic information system (GIS) to construct a stray prevention system for elderly persons suffering from dementia without interfering with their activities of daily livings. We also aim to(More)
BACKGROUND/PURPOSE Behavioral and psychologic symptoms of dementia (BPSD) are major sources of a caregiver's burden and also the most important factor when considering the need for institutionalization of dementia patients. BPSD occur in about 90% of patients with dementia. Studies comparing the BPSD in the major types of dementia using unitary behavioral(More)
The affective meaning of words can be quantified statistically by the 'semantic differential technique'. We studied a total of 55 Chinese adults in two experiments: first, 210 nouns were rated by 32 subjects. Factor analysis on these data yielded three independent semantic dimensions. Semantically unique words were used in electrophysiological experiments(More)
Conventional model-based or statistical analysis methods for functional MRI (fMRI) suffer from the limitation of the assumed paradigm and biased results. Temporal clustering methods, such as fuzzy clustering, can eliminate these problems but are difficult to find activation occupying a small area, sensitive to noise and initial values, and computationally(More)
BACKGROUND Recent schizophrenia research exploring the complicated pathogenesis of schizophrenia has focused on the subjects with at-risk mental states in order to exclude the influence of confounding factors. This study explores 3 sets of auditory-related event potentials in subjects with different risk levels of psychosis. METHODS Subjects were(More)
Epilepsy is a common chronic neurological disorder characterized by recurrent unprovoked seizures. The electroencephalogram (EEG) signals play an important role in the diagnosis of epilepsy. In addition, multi-channel EEG signals have much more discrimination information than a single channel. However, traditional recognition algorithms of EEG signals are(More)
Progranulin is the precursor of granulins, and its downregulation may lead to neurodegeneration. The single-nucleotide polymorphism rs5848 increases the risk of Alzheimer's disease (AD). We explored the association between alleles of rs5848 and the risk of AD in the Taiwanese population. The frequency of the homozygous TT genotype (16.4 vs. 10.0%) increased(More)
An automated method for detecting and eliminating electrocardiograph (ECG) artifacts from electroencephalography (EEG) without an additional synchronous ECG channel is proposed in this paper. Considering the properties of wavelet filters and the relationship between wavelet basis and characteristics of ECG artifacts, the concepts for selecting a suitable(More)
Alzheimer's disease (AD) is the most common neurodegenerative disease and is caused by an accumulation of A beta plaque deposits in the brains. Evidence is increasing that green tea flavonoids can protect cells from A beta-mediated neurotoxicity. However, the underlying mechanism remains unclear. Here, we used a human neuronal cell line MC65 conditional(More)
