In Europe, about 3% of the population has a panic attack in a given year while in the United States they affect about 11%. They are more common in females than in males. 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 panic 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 passed down through genes. For the non-phobias, the likelihood of inheriting is 30–40%, and for the phobias, it was 50–60%.
