Panic Disorder

The Smoke Detector in Overdrive

Your amygdala is like a smoke detector wired to protect your house from fire. In a healthy brain, the detector (amygdala) senses real smoke, the homeowner's brain (prefrontal cortex) checks the kitchen to confirm there is actually a fire, and if it is just burnt toast, the homeowner walks over and resets the alarm. GABA is like the reset button itself—it stops the alarm from blaring. Serotonin is like the homeowner's confidence and judgment that lets them calmly walk to the detector instead of panicking. In Panic Disorder, the detector becomes hypersensitive and fires at dust particles (a racing heartbeat, a memory of past panic). The homeowner is too exhausted from stress to walk over and check, so the alarm keeps screaming. The reset button (GABA) is stuck, and the homeowner has lost their nerve (low serotonin). The result: the alarm wails for ten minutes straight even though there is no fire, and next time the homeowner hears a creak, they expect the alarm to go off again.
