Obsessive compulsive and related disorders
The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) now includes a new chapter on obsessive compulsive and related disorders that reflects the growing evidence that several so called obsessive-compulsive spectrum disorders share common clinical and aetiological features and are distinguishable from other anxiety disorders. This hot topic will present recent neurobiological, experimental and clinical data characterizing disorders in this chapter, such as hoarding disorder, body-dysmorphic disorder and obsessive-compulsive disorder.
„Hoarding Disorder: The birth of a new mental disorder“
Hoarding disorder (HD) is a new mental disorder included under an equally new obsessive-compulsive and related disorders section in DSM-5. In this talk, I will summarise the process that led to the birth of the new disorder and describe its diagnostic criteria, accompanying specifiers and differential diagnosis. The differences between hoarding and normative collecting will be briefly outlined. I will then briefly review the growing literature on the epidemiology, risk factors, neural correlates, assessment and emerging treatment strategies for Hoarding Disorder
Professor Mataix-Cols is a clinical psychologist specialised in the study and clinical care of patients with obsessive-compulsive and related disorders. After completing his PhD in 1999, he joined the faculty of the University of Barcelona as a lecturer. In year 2000 he was awarded a Marie Curie Fellowship to conduct post-doctoral research at Imperial College London. From 2002, he was appointed lecturer at the Institute of Psychiatry, King’s College London, where he eventually became a full professor in 2012. At the same time, he developed his clinical activity at the Michael Rutter Centre, Maudsley Hospital. He is now professor of child and adolescent psychiatric science at the Karolinska Institutet, Stockholm, Sweden, where he runs a program of research aimed at understanding the causes of obsessive-compulsive and related disorders across the lifespan and the development of better and more cost-effective treatments for these conditions. He is author of over 170 peer-reviewed publications and recipient of multiple grants and awards from the UK, US, EU, Sweden and Spain. As former advisor to the DSM-5 Obsessive-Compulsive Spectrum Sub-Work Group he was instrumental to the inclusion of Hoarding Disorder as a separate mental disorder in the nomenclature. He is currently associate editor of the Journal of Obsessive-Compulsive and Related Disorders.

Psychobiology of obsessive compulsive disorder
Chair: Norbert Kathmann (Berlin)
The underlying causes and mechanisms of obsessive-compulsive disorder are poorly understood as yet. However, recent advances in brain imaging, genetic, and neurocognitive research promise progress in this field. The talks in this symposium will present cutting-edge research, including structural brain imaging meta- and mega-analyses, longitudinal twin and family studies addressing genetic origins of OCD spectrum disorders, connectivity studies with implications for psychobiological models of OCD, and data analyzing the relationship between psychopathological symptoms and neuropsychological deficits in OCD. Consequences for necessary future research will be discussed.
