Anxiety and Charles Bonnet syndrome. Within Spielberger's anxiety model, trait anxiety is described as a stable personality trait, whereas, state anxiety is a transient experience caused by a specific perceived threat.
When the intensity, duration, and/or frequency of anxiety become distressful and chronic, such that it interferes with a person's functioning, it is often referred to as pathological anxiety. Anxiety disorders represent variant forms of this pathological anxiety. Therefore, the difference between normal anxiety and abnormal anxiety is this: anxiety is considered normal and adaptive when it serves to improve peoples' functioning or wellbeing. In contrast, abnormal anxiety is a chronic condition that impairs peoples' functioning and interferes with their well-being.
