Question

Quizplus · Accepted Answer

Studies have suggested that an overactive autonomic nervous system may be a factor in the development of panic attacks. The limbic system, which includes the amygdala, plays a central role in anxiety disorders but an overstimulated limbic system may actually contribute to chronic anxiety. Environmental factors, such as traumatic experiences or chronic stress, can also be a significant contributor to the onset of anxiety disorders. Option A is false, as studies have shown that if one identical twin has an anxiety disorder, the other twin is significantly more likely to also develop an anxiety disorder. Option D is false, as environmental factors do play a significant role in the development of anxiety disorders.
