Today's show is about how to diagnose a phobia, with Dr. Kate Baker of the University of Michigan. In two weeks, we will be back with a second episode on treatment of phobias.
This episode may be most helpful for pre-clinical and clinical students, as well as residents early in their training.
In today's episode we cover:
- Specific phobias (like fear of flying, fear of getting an injection)
- Social phobia (also known as social anxiety disorder), which can include things like fear of public speaking
- Agoraphobia
- Fear neurocircuitry
Specific Phobia criteria: - intense anxiety, almost always provoked by stimulus - avoidance / endured with intense anxiety - anxiety out of proportion to actual danger - clinical distress or impairment (social, occupational, etc) - duration over 6 months - not better explained by another disorder
Social phobia: one additional criterion to the specific phobia criteria is: individual fears that he/she will act in a way or show anxiety symptoms that will be negatively evaluated, such as being rejected or embarrassed.
Agoraphobia: The additional criterion to specific phobia is two or more of the following: Fear of: - using public transportation - being in open spaces - being in enclosed spaces - being in a crowd or line - being outside the home alone
Basic steps of neurocircuitry: 1. signal of danger/trauma inputted into brain 2. brain puts context around this information 3. if brain interpretation is of concern, then fight/flight activated.
Key brain structure in the fear response is the amygdala.
