Question 1

My patient has both panic episodes and persistent worry - does the fear-vs-anxiety distinction change how I treat them?

Accepted Answer

Fear (amygdala-driven, phasic) and anxiety (BNST-driven, sustained) are biologically distinct responses that respond differently to treatment. Panic attacks map to the acute fear circuit and respond well to interoceptive exposure and benzodiazepines; chronic worry maps to BNST-driven sustained anxiety and responds better to SSRIs and cognitive restructuring. Patients with both need treatment strategies targeting each circuit.

Question 2

What's the clinical difference between amygdala-driven fear and BNST-driven anxiety?

Accepted Answer

Fear (amygdala-driven, phasic) and anxiety (BNST-driven, sustained) are biologically distinct responses that respond differently to treatment. Panic attacks map to the acute fear circuit and respond well to interoceptive exposure and benzodiazepines; chronic worry maps to BNST-driven sustained anxiety and responds better to SSRIs and cognitive restructuring. Patients with both need treatment strategies targeting each circuit.

Question 3

Does it matter whether my patient's problem is phasic panic or sustained worry when I design exposure?

Accepted Answer

Fear (amygdala-driven, phasic) and anxiety (BNST-driven, sustained) are biologically distinct responses that respond differently to treatment. Panic attacks map to the acute fear circuit and respond well to interoceptive exposure and benzodiazepines; chronic worry maps to BNST-driven sustained anxiety and responds better to SSRIs and cognitive restructuring. Patients with both need treatment strategies targeting each circuit.

Question 4

How does the LeDoux two-system framework translate into treatment decisions?

Accepted Answer

Fear (amygdala-driven, phasic) and anxiety (BNST-driven, sustained) are biologically distinct responses that respond differently to treatment. Panic attacks map to the acute fear circuit and respond well to interoceptive exposure and benzodiazepines; chronic worry maps to BNST-driven sustained anxiety and responds better to SSRIs and cognitive restructuring. Patients with both need treatment strategies targeting each circuit.

Question 5

Why does standard exposure work for panic but not as well for chronic worry?

Accepted Answer

Fear (amygdala-driven, phasic) and anxiety (BNST-driven, sustained) are biologically distinct responses that respond differently to treatment. Panic attacks map to the acute fear circuit and respond well to interoceptive exposure and benzodiazepines; chronic worry maps to BNST-driven sustained anxiety and responds better to SSRIs and cognitive restructuring. Patients with both need treatment strategies targeting each circuit.
