Illness anxiety disorder example-Young female with headaches comes in thinking she might have a brain tumor and that is causing her significant stress. Patients are significantly worried that their health is in danger and they fear severe illness/death.
Somatic symptom disorder- Young female with a history of headaches, abdominal pain, diarrhea/constipation presents to the E.R. with abdominal pain. Abdominal USG/CBC/etc. etc. NORMAL. All tests and labs come back NORMAL. The patient continues to have symptoms from different organ systems, usually depression/anxiety is associated here as well but that's only important for psych exams. 😉
