Towards a better understanding of the size and burden and cost of brain disorders in Europe: Editorial

This special issue was prepared within the framework of the European College of Neuropsychopharmacology (ECNP) Task Force on “Size and Burden of Mental Disorders in Europe”. The core aim of the Task Force was to describe the prevalence and the burden of treated and untreated mental disorders in all European member states and to highlight needs for further research. Ten state-of-theart epidemiological papers summarize the outcome of this project, making an attempt to provide for the first time ever prevalence estimates for a wide range of mental disorders, as well as for dementia and Parkinson’s disease in 28 European countries. These data also provide input for the European Brain Council (EBC, http://www.ebc-eurobrain. net) Initiative “Cost of Disorders of the Brain in Europe” aiming at estimating the cost of major classes of mental, neurological and neurosurgical disorders and conditions in Europe
