Document Summary
Anxiety disorders: characterized by unrealistic, unfounded fear and anxiety. Panic disorder, generalized anxiety disorder and social anxiety disorder. Possible causes: has a hereditary component; presence of the short allele of 5-ht is associated w/increase anxiety, the amygdala, cingulate, prefrontal and insular cortex are all associated. Increased activation of the amygdala is associated w/a higher severity of anxiety. Possible causes: the disorder is somewhat heritable; children who get the disorder are likely to have. Possible causes: the first idea was it was biological; but was argued soon after of being learned by introvert- ed and cold parents, now we know, parents are not to blame, and the disorder is biological. Heritable: the disorder can be heritable; can be due to mutations in neural development and commu- nication; concordance rate is higher with the autistic spectrum disorders than the other types. Brain pathology: medical disorders; especially those during prenatal development, have symptoms similar to autism.
