For environmental impacts, for example, GAD is significantly more prevalent in people who experienced a traumatic event in their life or were bullied, especially if either of these things occurred at a young age (Gliatto, 2000, p.2). Studies have also found that people who have lived through many important events in life are more likely to suffer from the disorder, as they are more worried that another impactful event could happen at any moment (Gliatto, p.1). As for genetics, studies found that GAD, along with panic disorder, was very likely to be transferred between family members (Woodman, …show more content…
