Question: Is obsessive compulsive disorder genetic? Dr. Helen Blair Simpson: There is a family history to obesity. The family studies suggest that if someone has OCD, there is a higher likelihood that there is OCD in their family members. So the typical prevalence rate of OCD is about 2%, you know, two out of a 100 in America will have it. But in those family studies, which you find as - again if you start with someone with OCD, their family members, it will be - the prevalence rate will be 10%, so 10 in a 100. So that's some suggestion that there is something going on in the families of OCD. However it gets a little more complicated. It seems like that so many true with some cases of OCD. So there is some families where there seems to be a familial aspect to the OCD, and there are other cases of OCD where there is no family history at all. The best can be determined from the data, it seems that really onset of OCD, meaning people who have the onset of OCD at young age are more likely to have family members with OCD than people who get OCD let's say in their late teens or 20s.
