CHRONIC FEAR ALTERS BRAIN CIRCUITRY AND CONNECTIVITY
Chronic fear disrupts adolescent brain development through several well-documented mechanisms that impact learning, emotional regulation, and social functioning.
Amygdala Hyperactivity: Prolonged fear heightens the activity of the amygdala, the brain’s main fear center. This overactivity makes the adolescent brain more sensitive to threats and increases anxiety. med.stanford+1
Impaired Prefrontal Cortex Regulation: The prefrontal cortex, responsible for decision-making and emotion regulation, develops more slowly under chronic fear. Increased “bottom-up” signals from the amygdala to the prefrontal cortex make it harder for adolescents to think clearly or regulate emotions. med.stanford
Weakening of Fear Extinction Circuits: Typically, the prefrontal cortex helps “turn off” fear responses when danger has passed (fear extinction). In anxious adolescents, poor connectivity between the prefrontal cortex, amygdala, and hippocampus makes it harder to unlearn fear, leading to persistent anxiety. pmc.ncbi.nlm.nih
These are the technical/biological reasons why Trump and his followers act more like impetuous teenagers than responsible adults.
