What goes on in your brain when you have anxiety?

Anxiety in the brain works as an overactive threat detection system, primarily involving the amygdala (fear center) misinterpreting signals, activating the "fight or flight" response via the hypothalamus and sympathetic nervous system, flooding the body with stress hormones like adrenaline. This heightened state disrupts the prefrontal cortex (logic center) from regulating the response, leading to persistent worry, hypervigilance, and physical symptoms, with chronic anxiety potentially altering brain structure and connectivity.
