Internet addiction or compulsive use of the internet has become an increasingly prevalent public health concern. The relationship between the clinical phenomenology and modes of brain dysfunction remains unclear. We describe an integrated series of clinical, neurobehavioral, and functional magnetic resonance imaging (fMRI) studies in patients with internet addiction. Based on findings from these studies, there appear to be at least four subtypes of internet addiction, including impulse control subtype, obsessive-compulsive subtype, inhibited (depressed-anxious) subtype, and combined impulse control and obsessive-compulsive subtype. fMRI studies reveal significantly decreased regional brain activation in response to targeted attention and working memory tasks in patients with internet addiction compared to healthy controls. After effective treatment, there appears to be normalization in brain circuitry; however, relapse in symptoms was associated with the reappearance of brain abnormalities. The need for transdisciplinary team interventions including psychiatry, neuropsychology, and innovative brain imaging techniques will be emphasized.
After the webinar, participants will be able to:
1. Describe the critical role of neuropsychology in the elucidation of potential brain mechanisms involved in the pathogenesis of internet addiction across the lifespan.
2. Identify key neuroimaging paradigms that are delineating regional brain abnormalities in internet addiction and their potential significance for enhanced diagnosis and treatment.
3. Discuss novel neurobehavioral and cognitive probes used during functional MRI studies and their role in further elucidating the pathogenesis of internet addiction.
Target Audience: Primary care providers, mental health providers, and direct patient care providers in other disciplines

Dr. David Rosenberg is Chair of the Department of Psychiatry & Behavioral Neurosciences at Wayne State where he also serves as the Director of the Translational Neurosciences Institute and the Miriam Hamburger Endowed Chair of Child Psychiatry. His research has focused on imaging genetic studies of neuropsychiatric disorders and he has led several large NIH consortium grants as lead PI at the lead/coordinating site. He has published extensively and been the recipient of numerous honors and awards including receiving first prize in the neuropsychoparmacology competition at the International Congress of Neuropsychopharmacology, the A.E. Bennett Award from the Society of Biological Psychiatry and the Psychiatric Times Teacher of the Year. He also published the first textbook on pediatric Psychopharmacology now in its third edition. He is frequently sought out by the national media and his research has been featured several times on the NBC Today Show, ABC 20/20, Good Morning America, ABC World News Tonight, CNN, PBS and NPR.
