Understanding anxiety symptoms as aberrant defensive responding along the threat imminence continuum

Summary & key facts

This paper is a review of many studies. The author suggests that common anxiety symptoms come from normal defensive reactions that have become too strong or too frequent. Those defensive reactions change depending on how close a threat seems — for example, early warning leads to worry and vigilance, closer or immediate threat leads to fast bodily arousal and escape actions. Framing anxiety this way may help explain why different anxiety disorders share many symptoms and point researchers toward common brain systems to study. The idea is a framework, not a proven treatment, and the paper calls for more research to test and apply it.

Key facts:

• The author reviewed evidence from animal and human studies and argues that defensive reactions to threat are organized by how imminent, or close, the threat appears in time or space.
• Researchers describe three rough phases of threat: before encounter (early warning), after noticing the threat, and immediate danger. Different kinds of responses tend to show up in each phase.
• Common anxiety symptoms such as excessive worry, high bodily arousal, and avoidance behavior are suggested to be exaggerated versions of normal defensive responses, not completely separate problems.
• The review highlights that many anxiety diagnoses share the same symptoms and likely share core brain and body mechanisms, which could explain why people often have more than one anxiety diagnosis.
• The paper is a conceptual and evidence-based framework. It does not claim to have proved a new treatment. It notes that links between symptoms and specific brain circuits are plausible but need more direct testing.
• Thinking of anxiety as overactive defensive responding could help scientists predict which symptoms will appear in which situations and guide future research on better-targeted treatments.
