Document Summary
Negative mood state characterized by bodily symptoms of physical tension and apprehension o o. Panic is a severely concentrated form of anxiety (meaning it is different from anxiety) Diathesis-stress model (predisposition to anxiety remains dormant until triggered) This system is activated by signals from the brainstem. These signals are sent due to unexpected events. This system/circuit is distinct from the circuit involved in panic. The panic circuit is called ffs or fight/flight system. This originates in the brain stem and goes through the midbrain (specifically the amygdala) Study showed that teens smoking 20+ cigarettes a day were 15x more likely to develop a panic disorder o. They were 5x more likely to develop gad. Patients with anxiety disorders exhibit overly responsive limbic systems when reacting to new information. The functions that down-regulate the stress response showed to be deficient. Children develop an understanding of their lack of control in their development.
