They often begin during puberty or early adulthood. Children and older people are less commonly affected. A meta-analysis was conducted on data collected about twin studies and family studies on the link between genes and<unk> nic disorder. The researchers also examined the possibility of a link to phobias, obsessive-compulsive disorder (OCD), and generalized anxiety disorder. The researchers used a database called MEDLINE to accumulate their data. The results concluded that the aforementioned disorders have a genetic component and are inherited or<unk> ssed down through genes.
