The EGOs study

The EGOs study is a study of genetic and environmental factors in obsessive-compulsive disorder, Tourette syndrome and tics. The purpose of the EGOs study is to identify genes and possible environmental factors that increase the risk of developing obsessive-compulsive disorder, Tourette's or tics. Psychiatric disorders are nowadays some of our most common diseases, but we have yet relatively poor knowledge of the reasons why people develop these.

Here at the Department of Medical Epidemiology and Biostatistics (MEB), we run a number of epidemiological studies with a focus on psychiatric disorders. We study environmental and genetic risk factors for autism, anorexia nervosa, ADHD, schizophrenia and bipolar disorder.
EGOs stands for Epidemiology and Genetics of OCD in Sweden and what we want to highlight with this name is that the risk factors for mental disorders are usually not due to a single cause or event but are instead the result of a complex combination of genetic and environmental factors. The basis of our research includes information collected through questionnaires, interviews, medical records and various types of registers which are then combined with biological samples such as blood and saliva. By examining these together, we can study the big picture and learn more about how biology and environment interact.
The EGOs study is a collaboration between Karolinska Institutet and Mount Sinai School of Medicine in New York, USA. It is also Mount Sinai School of Medicine that provides most of the funding of the study.
