TitleDisrupted Structural and Functional  Brain Pathways for Attention Processing in Attention Deficit/Hyperactivity  Disorder (ADHD)

Abstract:ADHD  manifests in early childhood with symptoms of inattention,  hyperactivity,  impulsivity, or a combination. It affects about 5 - 8% of  school age children and an estimated 60% of those will maintain the disorder  into adulthood; affects cognitive, academic, behavioral, emotional, and social  functioning; and requests annual direct costs conservatively estimated $36 - $54  billion in the U.S. Over the past decades, most neuroimaging research in ADHD  has focused on the impulsive tendencies, implicating dysfunction within  fronto-striatal circuits. The neurobiological foundation of inattention, the  other most significant component of the disorder, has not yet been well  studied.This talk will introduce a  series of studies, which suggest that inappropriate development of the pulvinar  nuclei of thalamus in children with ADHD may induce the disrupted  pulvinar-cortical circuits for attention processing, and further contribute to  the pathophysiological mechanisms of inattention of the disorder. Based on the  findings of this series of studies, future studies can assess the impact of the  treatments on the connectivity and efficiency of the pulvinar-cortical circuits  for attention processing, and suggest effective intervention  strategies.

Biography of Dr. Xiaobo LiDr. Xiaobo Li is the Director for Image  Analysis Section at Gruss Magnetic Resonance Research Center (MRRC),Assistant Professor at Departments of Radiology,  Neuroscience, Psychiatry and Behavioral Sciences,Albert Einstein College of Medicine, Yeshiva  University,NY, USA.She has received a Ph.D in Computer-Aided Geometric Design at  University of Birmingham, UK, 2001-2004. Her current research has a strong focus  on MR brain imaging and application problems.  She has extensive theoretical and  practical experiences in developing and translating mathematical techniques to  quantitatively evaluate the structural and functional organizations in the human  brain using structural MRI, DTI, and fMRI. 

Her Research Interests  include:§Functional MRI analysis – developing and  translating refined quantitative mathematical and statistical methodologies for  functional organization analyses to elucidate the pathophysiological mechanisms  underlying normal brain development, and disorders such as Schizophrenia, ADHD,  Depression, etc.. §Computational Neuroanatomy – developing  refined quantitative mathematical measures of cortical shape development and  geometric shape modeling of brain structures using structural MRI and  DTI§Integrated analyses of brain structure and  function applying structural MRI, fMRI, DTI, PET, EEG/MEG measures and  psychological and psychopharmacological factors.§Clinical Applications:§Functional and anatomical developments of  language processing circuit and default-mode network system during normal brain  maturation and onset of Schizophrenia.§Functional and anatomical impairments in  visual- and auditory-language processing circuit in patients with Schizophrenia,  ADHD, Autism, Depression,  other inheritable mental disorders, and the genetic  high-risk children and adolescents§Pharmacological stimulant effects to the  efficiency of default-mode network system and cognition in ADHD and  Autism
