What is trait anxity vs state anxiety? How does this cause anxiety illness?
Trait anxiety - individual’s potential to experience state anxiety. This is still not a mental illness but is genetically linked. Having high trait anxiety is usually useful. People with low trait anxiety have a high mortality rate under the age of 25yrs.
State anxiety - the problem with this is that it (1) causes avoidance, so you cannot unlearn the fear you have of that situation so it makes the anxiety worse. (2) Attentional and cognitive bias also occurs whereby the way you perceive the world changes. (3) Negative automatic thoughts is where your brain generates these constantly. This again leads to (4) poor sleep. Each of the factors causes perpetuation of anxiety.
Enough trait anxiety with state anxiety can lead to mental illness of anxiety.
