BACKGROUND Despite normal CT imaging and neurologic functioning, many individuals report postconcussion symptoms following mild traumatic brain injury (MTBI). This dissociation has been enigmatic for clinicians and investigators. METHODS Diffusion tensor imaging tractography of the corpus callosum was performed in 10 adolescents (14 to 19 years of age)(More)
Deletions of the PAFAH1B1 gene (encoding LIS1) in 17p13.3 result in isolated lissencephaly sequence, and extended deletions including the YWHAE gene (encoding 14-3-3ε) cause Miller-Dieker syndrome. We identified seven unrelated individuals with submicroscopic duplication in 17p13.3 involving the PAFAH1B1 and/or YWHAE genes, and using a 'reverse genomics'(More)
BACKGROUND AND PURPOSE DTI of normal-appearing WM as evaluated by conventional MR imaging in mTBI has the potential to identify important regional abnormalities that relate to PCS. VBA was used to examine WM changes in acute mTBI. MATERIALS AND METHODS WM was assessed between 1 and 6 days postinjury with voxel-based DTI analyses in 10 adolescent patients(More)
OBJECTIVES The aim of this study was to elucidate the frequency of major clinical manifestations in children with mitochondrial disease and establish their clinical course, prognosis, and rates of survival depending on their clinical features. METHODS We performed a retrospective review of the medical records of 400 patients who were referred for(More)
OBJECTIVE The ventrolateral nucleus of the thalamus (VL), based on its connectivity with the cerebellum and motor cortex, has long been considered to be involved with motor functions. We show that the human VL also plays a prominent role in sensory processing. METHODS Structural magnetic resonance imaging and diffusion tensor imaging were used to localize(More)
BACKGROUND AND PURPOSE Although the cerebellum has not attracted the same degree of attention as cortical areas and the hippocampus in traumatic brain injury (TBI) literature, there is limited structural and functional imaging evidence that the cerebellum is also vulnerable to insult. The cerebellum is emerging as part of a frontocerebellar system that,(More)
Compromised memory functioning is one of the commonly reported cognitive sequelae seen following mild traumatic brain injury (mTBI). Diffusion tensor imaging (DTI) has been shown to be sufficiently sensitive at detecting early microstructural pathological alterations after mTBI. Given its location and shape, the cingulate, which is comprised of the(More)
While closed head injury frequently results in damage to the frontal and temporal lobes, damage to deep cortical structures, such as the hippocampus, amygdala, and basal ganglia, has also been reported. Five deep central structures (hippocampus, amygdala, globus pallidus, putamen, and caudate) were examined in 16 children (eight males, eight females; aged(More)
AIM Angelman syndrome is a neurogenetic disorder characterized by severe intellectual disability, absent speech, seizures, and outbursts of laughter. The aim of this study was to utilize diffusion tensor imaging (DTI) to examine alterations in white matter pathways in Angelman syndrome, with an emphasis on correlations with clinical severity.
