Research Summary

Dr. Leckman is widely recognized as a master clinician with special skills in the evaluation and treatment of Tourette's syndrome (TS) and early onset obsessive-compulsive disorder (OCD). Since the early 1980s, he has seen and evaluated hundreds of individuals with these conditions. In 1999, he edited with Dr. Donald J. Cohen, Tourette's Syndrome: Tics, Obsessions, Compulsions - Developmental Psychopathology and Clinical Care, published by John Wiley & Sons. Given its success, this volume was re-issued in paperback in 2001. More recently, Dr. Leckman edited (along with Davide Martino) a 30-chapter volume, entitled, Tourette Syndrome published in 2014 by Oxford University Press. Dr. Leckman's specific research interests include the interaction of genes and environment in the pathogenesis of TS and OCD. His research on these disorders is well known and multifaceted from phenomenology and natural history, to neurobiology (neuroimaging, neuroendocrinology, neuroimmunology) to genetics, to risk factor research (perinatal factors are important), to treatment studies.

Interdisciplinary research program on TS & OCD

One of Dr. Leckman’s main research interests has been the interaction of genes and environment in the pathogenesis of TS and OCD. His research on these disorders is well known and multifaceted from phenomenology and natural history, to neurobiology (neuroimaging, neuroendocrinology, neuroimmunology) to genetics, to risk factor research (perinatal factors are important), to treatment studies.

Formative Childhood and Peace Building

Most recently, in partnership with colleagues at UNICEF and the Mother-Child Education Foundation based in Turkey, Dr. Leckman has begun to explore the question whether strengthening families and enhancing child development is a path to peace and violence prevention. Related efforts include the Early Childhood Peace Consortium that was launched (September 2013) in New York in at the United Nations and the 15th Ernst Strüngmann Forum that took place in Frankfurt, Germany in October 2013. The deliberations of 40 international experts from a broad range of scientific disciplines are summarized in volume entitled, Formative Childhoods: The Transformative Power of Children and Families, published by the Massachusetts Institute of Technology Press in 2014.
