Behavioral variant frontotemporal dementia (bvFTD) erodes complex social-emotional functions as the anterior cingulate cortex (ACC) and frontoinsula (FI) degenerate, but the early vulnerable neuron within these regions has remained uncertain. Previously, we demonstrated selective loss of ACC von Economo neurons (VENs) in bvFTD. Unlike ACC, FI contains a(More)
The"closing-in phenomenon"in figure copying tasks refers to a tendency to copy near the target, or to overlap the target to be copied. The mechanisms underlying the closing-in phenomenon have not been fully elucidated. We posit that closing-in may be related to the patients'compensatory strategies to overcome visuospatial dysfunction or visuospatial working(More)
Patients with right hemisphere injury often omit or misread words on the left side of a page or the beginning letters of single words (neglect dyslexia). Our study involving a large sample of acute right hemisphere stroke investigated (1) the frequency of neglect dyslexia (ND), (2) the association between ND and other types of contralesional hemispatial(More)
Findings and conclusions of this report are those of the authors and do not necessarily reflect the policies of either of these funding sources. one of the nation' s oldest multidisciplinary centers devoted to the study of children and families. Our mission is to cultivate and share knowledge that enhances child development and family well being.(More)
Recent reports have suggested that hemispatial neglect may be a vestibular disorder at the cortical level, based on the similarities of symptoms and neural correlates between the two phenomena. If this is the case, peripheral vestibulopathy may lead to hemispatial neglect. However, the etiology of hemispatial neglect in patients with unilateral peripheral(More)
A family with paramyotonia congenita (PC) is presented. At least 10 family members were affected in an autosomal dominant inheritance pattern. The proband had cold-sensitive muscle stiffness, paradoxical myotonia, and intermittent muscle weakness since childhood. The serum level of creatine kinase was mildly elevated and short exercise test with cooling(More)
Frontotemporal lobar degeneration (FTLD) can be subdivided into frontotemporal dementia (FTD), FTD combined with motor neuron disease (FTD-MND), semantic dementia (SD), and progressive nonfluent aphasia (PNFA). FTLD has been considered a rare disorder, and its' demographic and survival data have rarely been studied in Asian population. A survival analysis(More)
Several genetic and environmental factors place youth offspring of parents with bipolar disorder (BD) at high risk for developing mood and anxiety disorders. Recent studies suggest that anxiety symptoms, even at subclinical levels, have been associated with an increased risk for developing BD. The brain-derived neurotrophic factor (BDNF) gene has been(More)
OBJECTIVES This study examined the effect of osmotic-controlled release oral delivery system-methylphenidate (OROS-MPH) on the adaptive functioning of children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and investigated the relationship between reduced ADHD symptoms and improvements in functioning and factors that are predictive of(More)
The behavioral variant of frontotemporal dementia (bvFTD) slowly undermines emotion, social behavior, personal conduct, and decision making. These deficits occur in concert with focal neurodegeneration that can be quantified with modern structural and functional imaging and neuropathological methods. As a result, studies of bvFTD have helped to clarify(More)
